The introductory paper Orthodox Editors introduced some ideas on which this page was build. Here is the abstract of the paper:

This paper tried to introduce a new concept: orthodox editors as a special category of editors. All of them have command line set of commands and respective glue macrolanguage. We have found two such families:

We define the notion of  "orthodox editors" as having the following distinct features:

  1. They have a well-defined command set that is comparable in power to GUI based commands and command line can be used to enter editor commands. For some of them (vi - line ) that comes naturally, from the fact that they were initially designed for typewriters. 
  2. They permit doing any editing task using keyboard  (although mouse can speed up or simplify many of those tasks and is not rejected in the extremist way)
  3. They use a standard scripting language as a macrolanguage (TCL, REXX) or unique for the application (YASL  - yet another scripting language) like in vim 6 as a macrolanguage. It serves as a glue for the command set implemented by the editor. With some reservations we can accept  a unique for the application (YASL  - yet another scripting language) like in VIM. This is definitely less attractive solution as it is difficult to master the language that you use only for a specific application (in this case an editor).  The same consideration is applicable to Emacs. 
  4. They support folding (all command in XEDIT and its derivatives; folding capabilities in VIM )
  5. They distinguish between editing buffer and the windows in which this editing buffer is displayed allowing multiple windows to display the same buffer.
  6. They support regular expressions
  7. They permit processing selected part of the editing buffer or all the buffer via pipe connected to external command (! command in vi)
  8. They support multiple views of the same editing buffer.
  9. They allow piping in output from arbitrary pipe into the current position of cursor, selection, or all buffer as well as exporting a selection or all buffer as an input stream for an arbitrary pipe.  

This article is a modest attempt to create a basic classification useful for further studying this important class of editors. The author argues that this class of editors can serve as viable mid-weight editors for programmers (see a companion paper A Note on Size-based Classification of Text Editors for this further discussion of related ideas).

This article is a modest attempt to create a basic classification useful for further studying this important class of editors. The author argues that this class of editors can serve as viable editors for programmers providing despite Spartan interface rich functionality absent in almost any other editor with possible exception of vi and its derivatives. Despite integrating a macro language they are actually pretty small, mid-weight by some standards (see a companion paper A Note on Size-based Classification of Text Editors for this further discussion of related ideas).

Please note that both subclasses of orthodox editors were pioneers in introducing several important for any modern editor features, features that unfortunately still are absent or poorly implemented in most other editors: 

This paper explores two sets of  deep interconnections that were previously unnoticed in the literature:

Actually the second point was the main reason that I decided to use a superclass term "orthodox editors" that includes as subclasses both XEDIT editors line and VI editors lines. Not only because I like to invent new terms (that goes with Ph.D ;-), but I really see deep similarities between them and their connection to a similar phenomenon that I studied earlier in case of File Managers (see OFM page for details). Those tools are representative of a different approach to GUI interface then Apple GUI or Microsoft GUI (which are converging). Interface that can be called "Orthodox Interface".  And this Spartan interface with ancient-looking, "half-baked" GUI with command line present give users important and unique capabilities that are missing in other similar "pure GUI" Tools. They survived because they are capable of giving advanced users the ability to achieve an extremely high productivity, beating competition. Although some design decisions in those editors were dictated by limitation of old hardware they withstand the test of time and proved to be useful and extremely productive tools for modern environments.

Another interesting for me issue is the value of editors of different sizes (lightweight, mid-weight and heavyweight). My thought on this issue are reflected in another paper  A Note on Size-based Classification of Text Editors  Here is the abstract:

The article presents an attempt to understand correlation between features of text editors and editor size based of tasks each weight category performs better and1 propose size based classification of editors

The concept of "editor weight" is useful for explaining why most programmers use several editors (usually three: standalone lightweight editor like Notepad, midweight editor like Vim, Kedit or SlickEdit and heavyweight editor /IDE type of environments like Microsoft Visual Studio .Net, Emacs, etc). 

That suggests that there are tasks for which one editor of a certain size suit best and perfoming of which with the editor of a different category is less efficient despite the additional power it might provide. This paradox that most programmers use several editors while leading one would be more efficient can be explained by the hypothesis that editors can be classified into three distinct categories and that each category of editors has its own unique set of features In this case one size does not fit all. We will distinguish 

The main idea here that there are tasks that are better, quicker performed by lightweight editors and they're are tasks that are better performed by midweight/heavyweight editors, so those categories of editors develop in different directions.

Most programmers spend  a lot of time editing the code (may as much as 40%). If that's the case, finding the best tool available and, if necessary, spending a few extra dollars for it definitely is a good investment.

[Nov 12, 2018] Vim buffer FAQ

Notable quotes:
"... A buffer is a file loaded into memory for editing. All opened files are associated with a buffer. There are also buffers not associated with any file. ..."
Nov 12, 2018 | vim.wikia.com

Named Buffers

You can use a Named buffer with any of the Delete, Yank, or Put commands. Each of the 26 Named buffers is named by a letter of the alphabet. Each Named buffer can store a different block of text and you can recall each block as needed. Unlike the General-Purpose buffer, vim does not change the contents of a Named buffer unless you issue a command that specifically overwrites that buffer. The vim editor maintains the contents of the Named buffers throughout an editing session.

The vim editor stores text in a Named buffer if you precede a Delete or Yank command with a double quotation mark ( " ) and a buffer name (for example, " kyy yanks a copy of the current line into buffer k ). You can put information from the Work buffer into a Named buffer in two ways. First, if you give the name of the buffer as a lowercase letter, vim overwrites the contents of the buffer when it deletes or yanks text into the buffer. Second, if you use an uppercase letter for the buffer name, vim appends the newly deleted or yanked text to the end of the buffer. This feature enables you to collect blocks of text from various sections of a file and deposit them at one place in the file with a single command. Named buffers are also useful when you are moving a section of a file and do not want to give a Put command immediately after the corresponding Delete command, and when you want to insert a paragraph, sentence, or phrase repeatedly in a document.

If you have one sentence you use throughout a document, you can yank that sentence into a Named buffer and put it wherever you need it by using the following procedure: After entering the first occurrence of the sentence and pressing ESCAPE to return to Command mode, leave the cursor on the line containing the sentence. (The sentence must appear on a line or lines by itself for this procedure to work.) Then yank the sentence into Named buffer a by giving the " ayy command (or " a2yy if the sentence takes up two lines). Now anytime you need the sentence, you can return to Command mode and give the command " ap to put a copy of the sentence below the current line.

This technique provides a quick and easy way to insert text that you use frequently in a document. For example, if you were editing a legal document, you might store the phrase The Plaintiff alleges that the Defendant in a Named buffer to save yourself the trouble of typing it every time you want to use it. Similarly, if you were creating a letter that frequently used a long company name, such as National Standards Institute , you might put it into a Named buffer.

Numbered Buffers

In addition to the 26 Named buffers and 1 General-Purpose buffer, 9 Numbered buffers are available. They are, in one sense, readonly buffers. The vim editor fills them with the nine most recently deleted chunks of text that are at least one line long. The most recently deleted text is held in " 1 , the next most recent in " 2 , and so on. If you delete a block of text and then give other vim commands so that you cannot reclaim the deleted text with an Undo command, you can use " 1p to paste the most recently deleted chunk of text below the location of the cursor. If you have deleted several blocks of text and want to reclaim a specific one, proceed as follows: Paste the contents of the first buffer with "1p . If the first buffer does not hold the text you are looking for, undo the paste operation with u and then give the period ( . ) command to repeat the previous command. The Numbered buffers work in a unique way with the period command: Instead of pasting the contents of buffer " 1 , the period command pastes the contents of the next buffer ( " 2 ). Another u and period would replace the contents of buffer " 2 with that of buffer " 3 , and so on through the nine buffers.

What is a Vim buffer?

A buffer is a file loaded into memory for editing. All opened files are associated with a buffer. There are also buffers not associated with any file.

:help windows-intro

How do I identify a buffer?

Vim buffers are identified using a name and a number. The name of the buffer is the name of the file associated with that buffer. The buffer number is a unique sequential number assigned by Vim. This buffer number will not change in a single Vim session.

:help buffers

How do I create a buffer?

When you open a file using any of the Vim commands, a buffer is automatically created. For example, if you use :edit file to edit a file, a new buffer is automatically created. An empty buffer can be created by entering :new or :vnew .

How do I add a new buffer for a file to the buffer list without opening the file?

You can add a new buffer for a file without opening it, using the ":badd" command. For example,

:badd f1.txt
:badd f2.txt

The above commands will add two new buffers for the files f1.txt and f2.txt to the buffer list.

:help :badd

How do I get a list of all the existing buffers?

You can get a list of all the existing buffers using the ":buffers" or ":ls" or ":files" command. This list is called the 'buffer list'.

To display all the buffers including unlisted buffers, use the ":buffers!" or ":ls!" or ":files!" command.

How do I delete a buffer?

You can delete a buffer using the ":bdelete" command. You can use either the buffer name or the buffer number to specify a buffer. For example,

:bdelete f1.txt
:bdelete 4

The above commands will delete the buffer named "f1.txt" and the fourth buffer in the buffer list. The ":bdelete" command will remove the buffer from the buffer list.

When a buffer is deleted, the buffer becomes an unlisted-buffer and is no longer included in the buffer list. But the buffer name and other information associated with the buffer is still remembered. To completely delete the buffer, use the ":bwipeout" command. This command will remove the buffer completely (i.e. the buffer will not become a unlisted buffer).

How do I delete multiple buffers?

You can delete multiple buffers in several ways:

:3,5bdelete
:bdelete buf1.txt buf2.c buf3.h

In this example, after typing ":bdelete buf", you can press <Ctrl-A> to expand all the buffer names starting with 'buf'.

How do I remove a buffer from a window?

You can remove a buffer displayed in a window in several ways:

  1. Close the window or edit another buffer/file in that window.
  2. Use the ":bunload" command. This command will remove the buffer from the window and unload the buffer contents from memory. The buffer will not be removed from the buffer list.

:help :bunload

How do I edit an existing buffer from the buffer list?

You can edit or jump to a buffer in the buffer list in several ways:

  1. Use the ":buffer" command passing the name of an existing buffer or the buffer number. Note that buffer name completion can be used here by pressing the <Tab> key.
  2. You can enter the buffer number you want to jump/edit and press the Ctrl-^ key.
  3. Use the ":sbuffer" command passing the name of the buffer or the buffer number. Vim will split open a new window and open the specified buffer in that window.
  4. You can enter the buffer number you want to jump/edit and press the Ctrl-W ^ or Ctrl-W Ctrl-^ keys. This will open the specified buffer in a new window.

How do I browse through all the available buffers?

You can browse through the buffers in the buffer list in several ways:

  1. To jump to the first buffer in the buffer list, use the ":bfirst" or ":brewind" command.
  2. To jump to the first buffer in the buffer list in a new window, use the ":sbfirst" or ":sbrewind" command.
  3. To edit the next buffer in the buffer list, use the ":bnext" command., or the abbreviated ":bn"
  4. To open the next buffer in the buffer list in a new window, use the ":sbnext" command.
  5. To edit the previous buffer in the buffer list, use the ":bprevious" or ":bNext" command. or the abbreviated ":bp"
  6. To open the previous buffer in the buffer list in a new window, use the ":sbprevious" or ":sbNext" command.
  7. To open the last buffer in the buffer list, use the ":blast" command.
  8. To open the last buffer in the buffer list in a new window, use the ":sblast" command.

How do I open all the buffers in the buffer list?

You can open all the buffers present in the buffer list using the ":ball" or ":sball" commands.

How do I open all the loaded buffers?

You can open all the loaded buffers in the buffer list using the ":unhide" or ":sunhide" commands. Each buffer will be loaded in a separate new window.

How do I open the next modified buffer?

You can open the next or a specific modified buffer using the ":bmodified" command. You can open the next or a specific modified buffer in a new window using the ":sbmodified" command.

Is there a simpler way for using the buffers under gvim (GUI Vim)?

Yes, use the 'Buffers' menu to list all the buffers. You can select a buffer name to edit the buffer. You can also delete a buffer or browse the buffer list. Click the dashed line at the top of the menu to tear it off so you can always see a list of the buffers.

:help buffers-menu

Is there a Vim script that simplifies using buffers with Vim?

Yes, try the Buffer Explorer , minibufexpl or bufmru plugins.

Is it possible to save and restore the buffer list across Vim sessions?

Yes. To save and restore the buffer list across Vim session, include the '%' flag in the 'viminfo' option. Note that if Vim is invoked with a filename argument, then the buffer list will not be restored from the last session. To use buffer lists across sessions, invoke Vim without passing filename arguments.

We can save different buffer list for different folders, by setting a local 'viminfo' file.

http://www.vim.org/scripts/script.php?script_id=441

The point is to overwrite the global setting by calling local setting after the 'viminfo' setting, for example.

set viminfo='1025,f1,%1024
call SetLocalOptions(".")

How do I remove all the entries from the buffer list?

You can remove all the entries in the buffer list by starting Vim with a file argument. You can also manually remove all the buffers using the ":bdelete" command.

What is a hidden buffer?

A hidden buffer is a buffer with some unsaved modifications and is not displayed in a window. Hidden buffers are useful, if you want to edit multiple buffers without saving the modifications made to a buffer while loading other buffers.

How do I load buffers in a window, which currently has a buffer with unsaved modifications?

By setting the option 'hidden', you can load a buffer in a window that currently has a modified buffer. Vim will remember your modifications to the buffer. When you quit Vim, you will be asked to save the modified buffers. It is important to note that, if you have the 'hidden' option set, and you quit Vim forcibly, for example using ":quit!", then you will lose all your modifications to the hidden buffers.

:help 'hidden'

Is it possible to unload or delete a buffer when it becomes hidden?

By setting the 'bufhidden' option to either 'hide' or 'unload' or 'delete', you can control what happens to a buffer when it becomes hidden. When 'bufhidden' is set to 'delete', the buffer is deleted when it becomes hidden. When 'bufhidden' is set to 'unload', the buffer is unloaded when it becomes hidden. When 'bufhidden' is set to 'hide', the buffer is hidden.

:help 'bufhidden'

How do I execute a command on all the buffers in the buffer list?

You can use the ":bufdo" command to execute a command on all the buffers in the buffer list.

:help :bufdo

When I open an existing buffer from the buffer list, if the buffer is already displayed in one of the existing windows, I want Vim to jump to that window instead of creating a new window for this buffer. How do I do this?

When opening a buffer using one of the split open buffer commands (:sbuffer, :sbnext), Vim will open the specified buffer in a new window. If the buffer is already opened in one of the existing windows, then you will have two windows containing the same buffer. You can change this behavior by setting the 'switchbuf' option to 'useopen'. With this setting, if a buffer is already opened in one of the windows, Vim will jump to that window, instead of creating a new window.

:help 'switchbuf'

What information is stored as part of a buffer?

Every buffer in the buffer list contains information about the last cursor position, marks, jump list, etc.

What is the difference between deleting a buffer and unloading a buffer?

When a buffer is unloaded, it is not removed from the buffer list. Only the file contents associated with the buffer are removed from memory. When a buffer is deleted, it is unloaded and removed from the buffer list. A deleted buffer becomes an 'unlisted' buffer.

Is it possible to configure Vim, by setting some option, to re-use the number of a deleted buffer for a new buffer?

No. Vim will not re-use the buffer number of a deleted buffer for a new buffer. Vim will always assign the next sequential number for a new buffer. The buffer number assignment is implemented this way, so that you can always jump to a buffer using the same buffer number. One method to achieve buffer number reordering is to restart Vim. If you restart Vim, it will re-assign numbers sequentially to all the buffers in the buffer list (assuming you have properly set 'viminfo' to save and restore the buffer list across Vim sessions).

:help buffers

How is a scratch (temporary) buffer created?

In any buffer (for example, after entering :new to create a new buffer), enter the following options to change the current buffer to a scratch buffer:

:setlocal buftype=nofile
:setlocal bufhidden=hide
:setlocal noswapfile

This creates a temporary buffer which is not associated with a file, which does not have an associated swap file, and which will be hidden when its window is closed. On exit, Vim discards any text in a scratch buffer without warning.

Also you can use scratch.vim for creating a scratch buffer.

How do I prevent a buffer from being added to the buffer list?

You can prevent a buffer from being added to the buffer list by resetting the 'buflisted' option.

:set nobuflisted

:help 'buflisted'

How do I determine whether a buffer is modified or not?

There are several ways to find out whether a buffer is modified or not. The simplest way is to look at the status line or the title bar. If the displayed string contains a '+' character, then the buffer is modified. Another way is to check whether the 'modified' option is set or not. If 'modified' is set, then the buffer is modified. To check the value of modified, use

:set modified?

You can also explicitly set the 'modified' option to mark the buffer as modified like this:

:set modified

:help 'modified'

How can I prevent modifications to a buffer?

You can prevent any modification to a buffer by re-setting the 'modifiable' option. To reset this option, use

:set nomodifiable

To again allow modifications to the buffer, use:

:set modifiable

:help 'modifiable'

How do I set options specific to the current buffer?

You can set Vim options which are specific to a buffer using the "setlocal" command. For example,

:setlocal textwidth=70

This will set the 'textwidth' option to 70 only for the current buffer. All other buffers will have the default or the previous 'textwidth' value.

How do I define mappings specific to the current buffer?

You can define mappings specific to the current buffer by using the keyword "<buffer>" in the map command. For example,

:map <buffer> ,w /[.,;]<CR>

:help map-local

How do I define abbreviations specific to the current buffer?

You can define abbreviations specific to the current buffer by using the keyword "<buffer>" in the :abbreviate command. For example,

:abb <buffer> FF for (i = 0; i < ; ++i)

:help abbreviate-local

[Oct 23, 2018] To switch from vertical split to horizontal split fast in Vim

Nov 24, 2013 | stackoverflow.com

ДМИТРИЙ МАЛИКОВ, Nov 24, 2013 at 7:55

How can you switch your current windows from horizontal split to vertical split and vice versa in Vim?

I did that a moment ago by accident but I cannot find the key again.

Mark Rushakoff

Vim mailing list says (re-formatted for better readability):

  • To change two vertically split windows to horizontal split: Ctrl - W t Ctrl - W K
  • Horizontally to vertically: Ctrl - W t Ctrl - W H

Explanations:

  • Ctrl - W t -- makes the first (topleft) window current
  • Ctrl - W K -- moves the current window to full-width at the very top
  • Ctrl - W H -- moves the current window to full-height at far left

Note that the t is lowercase, and the K and H are uppercase.

Also, with only two windows, it seems like you can drop the Ctrl - W t part because if you're already in one of only two windows, what's the point of making it current?

Too much php Aug 13 '09 at 2:17

So if you have two windows split horizontally, and you are in the lower window, you just use ^WL

Alex Hart Dec 7 '12 at 14:10

There are a ton of interesting ^w commands (b, w, etc)

holms Feb 28 '13 at 9:07

somehow doesn't work for me.. =/ –

Lambart Mar 26 at 19:34

Just toggle your NERDTree panel closed before 'rotating' the splits, then toggle it back open. :NERDTreeToggle (I have it mapped to a function key for convenience).

xxx Feb 19 '13 at 20:26

^w followed by capital H , J , K or L will move the current window to the far left , bottom , top or right respectively like normal cursor navigation.

The lower case equivalents move focus instead of moving the window.

respectTheCode, Jul 21 '13 at 9:55

1 Wow, cool! Thanks! :-) – infous Feb 6 at 8:46 it's much better since users use hjkl to move between buffers. – Afshin Mehrabani

In VIM, take a look at the following to see different alternatives for what you might have done:

:help opening-window

For instance:

Ctrl - W s
Ctrl - W o
Ctrl - W v
Ctrl - W o
Ctrl - W s

Anon, Apr 29 at 21:45

The command ^W-o is great! I did not know it. – Masi Aug 13 '09 at 2:20 add a comment | up vote 6 down vote The following ex commands will (re-)split any number of windows:

If there are hidden buffers, issuing these commands will also make the hidden buffers visible.

Mark Oct 22 at 19:31

When you have two or more windows open horizontally or vertically and want to switch them all to the other orientation, you can use the following:

:command! -bang -range -nargs=1 -complete=file MoveAppend <line1>,<line2>write<bang> >> <args> | <line1>,<line2>delete _

greg0ire ,Jan 23, 2013 at 15:27

This is very ugly, but hey, it seems to do in one step exactly what I asked for (I tried). +1, and accepted. I was looking for a native way to do this quickly but since there does not seem to be one, yours will do just fine. Thanks! – greg0ire Jan 23 '13 at 15:27

Ingo Karkat ,Jan 23, 2013 at 16:15

Beauty is in the eye of the beholder. I find this pretty elegant; you only need to type it once (into your .vimrc). – Ingo Karkat Jan 23 '13 at 16:15

greg0ire ,Jan 23, 2013 at 16:21

You're right, "very ugly" shoud have been "very unfamiliar". Your command is very handy, and I think I definitely going to carve it in my .vimrc – greg0ire Jan 23 '13 at 16:21

embedded.kyle ,Jan 23, 2013 at 14:08

By "move a piece of text to a new file" I assume you mean cut that piece of text from the current file and create a new file containing only that text.

Various examples:

The above only copies the text and creates a new file containing that text. You will then need to delete afterward.

This can be done using the same range and the d command:

Or by using dd for the single line case.

If you instead select the text using visual mode, and then hit : while the text is selected, you will see the following on the command line:

:'<,'>

Which indicates the selected text. You can then expand the command to:

:'<,'>w >> old_file

Which will append the text to an existing file. Then delete as above.


One liner:

:2,3 d | new +put! "

The breakdown:

greg0ire, Jan 23, 2013 at 14:09

Your assumption is right. This looks good, I'm going to test. Could you explain 2. a bit more? I'm not very familiar with ranges. EDIT: If I try this on the second line, it writes the first line to the other file, not the second line. – greg0ire Jan 23 '13 at 14:09

embedded.kyle ,Jan 23, 2013 at 14:16

@greg0ire I got that a bit backward, I'll edit to better explain – embedded.kyle Jan 23 '13 at 14:16

greg0ire ,Jan 23, 2013 at 14:18

I added an example to make my question clearer. – greg0ire Jan 23 '13 at 14:18

embedded.kyle ,Jan 23, 2013 at 14:22

@greg0ire I corrected my answer. It's still two steps. The first copies and writes. The second deletes. – embedded.kyle Jan 23 '13 at 14:22

greg0ire ,Jan 23, 2013 at 14:41

Ok, if I understand well, the trick is to use ranges to select and write in the same command. That's very similar to what I did. +1 for the detailed explanation, but I don't think this is more efficient, since the trick with hitting ':' is what I do for the moment. – greg0ire Jan 23 '13 at 14:41

Xyon ,Jan 23, 2013 at 13:32

Select the text in visual mode, then press y to "yank" it into the buffer (copy) or d to "delete" it into the buffer (cut).

Then you can :split <new file name> to split your vim window up, and press p to paste in the yanked text. Write the file as normal.

To close the split again, pass the split you want to close :q .

greg0ire ,Jan 23, 2013 at 13:42

I have 4 steps for the moment: select, write, select, delete. With your method, I have 6 steps: select, delete, split, paste, write, close. I asked for something more efficient :P – greg0ire Jan 23 '13 at 13:42

Xyon ,Jan 23, 2013 at 13:44

Well, if you pass the split :x instead, you can combine writing and closing into one and make it five steps. :P – Xyon Jan 23 '13 at 13:44

greg0ire ,Jan 23, 2013 at 13:46

That's better, but 5 still > 4 :P – greg0ire Jan 23 '13 at 13:46 Based on @embedded.kyle's answer and this Q&A , I ended up with this one liner to append a selection to a file and delete from current file. After selecting some lines with Shift+V , hit : and run:
'<,'>w >> test | normal gvd

The first part appends selected lines. The second command enters normal mode and runs gvd to select the last selection and then deletes.

[Oct 22, 2018] Cut/copy and paste using visual selection

Oct 22, 2018 | vim.wikia.com
Visual selection is a common feature in applications, but Vim's visual selection has several benefits.

To cut-and-paste or copy-and-paste:

  1. Position the cursor at the beginning of the text you want to cut/copy.
  2. Press v to begin character-based visual selection, or V to select whole lines, or Ctrl-v or Ctrl-q to select a block.
  3. Move the cursor to the end of the text to be cut/copied. While selecting text, you can perform searches and other advanced movement.
  4. Press d (delete) to cut, or y (yank) to copy.
  5. Move the cursor to the desired paste location.
  6. Press p to paste after the cursor, or P to paste before.

Visual selection (steps 1-3) can be performed using a mouse.

If you want to change the selected text, press c instead of d or y in step 4. In a visual selection, pressing c performs a change by deleting the selected text and entering insert mode so you can type the new text.

Pasting over a block of text

You can copy a block of text by pressing Ctrl-v (or Ctrl-q if you use Ctrl-v for paste), then moving the cursor to select, and pressing y to yank. Now you can move elsewhere and press p to paste the text after the cursor (or P to paste before). The paste inserts a block (which might, for example, be 4 rows by 3 columns of text).

Instead of inserting the block, it is also possible to replace (paste over) the destination. To do this, move to the target location then press 1vp ( 1v selects an area equal to the original, and p pastes over it).

When a count is used before v , V , or ^V (character, line or block selection), an area equal to the previous area, multiplied by the count, is selected. See the paragraph after :help <LeftRelease> .

Note that this will only work if you actually did something to the previous visual selection, such as a yank, delete, or change operation. It will not work after visually selecting an area and leaving visual mode without taking any actions.

See also Comments

NOTE: after selecting the visual copy mode, you can hold the shift key while selection the region to get a multiple line copy. For example, to copy three lines, press V, then hold down the Shift key while pressing the down arrow key twice. Then do your action on the buffer.

I have struck out the above new comment because I think it is talking about something that may apply to those who have used :behave mswin . To visually select multiple lines, you type V , then press j (or cursor down). You hold down Shift only to type the uppercase V . Do not press Shift after that. If I am wrong, please explain here. JohnBeckett 10:48, October 7, 2010 (UTC)

If you just want to copy (yank) the visually marked text, you do not need to 'y'ank it. Marking it will already copy it.

Using a mouse, you can insert it at another position by clicking the middle mouse button.

This also works in across Vim applications on Windows systems (clipboard is inserted)


This is a really useful thing in Vim. I feel lost without it in any other editor. I have some more points I'd like to add to this tip:


You can replace a set of text in a visual block very easily by selecting a block, press c and then make changes to the first line. Pressing <Esc> twice replaces all the text of the original selection. See :help v_b_c .


On Windows the <mswin.vim> script seems to be getting sourced for many users.

Result: more Windows like behavior (ctrl-v is "paste", instead of visual-block selection). Hunt down your system vimrc and remove sourcing thereof if you don't like that behavior (or substitute <mrswin.vim> in its place, see VimTip63 .

With VimTip588 one can sort lines or blocks based on visual-block selection.


With reference to the earlier post asking how to paste an inner block

  1. Select the inner block to copy usint ctrl-v and highlighting with the hjkl keys
  2. yank the visual region (y)
  3. Select the inner block you want to overwrite (Ctrl-v then hightlight with hjkl keys)
  4. paste the selection P (that is shift P) , this will overwrite keeping the block formation

The "yank" buffers in Vim are not the same as the Windows clipboard (i.e., cut-and-paste) buffers. If you're using the yank, it only puts it in a Vim buffer - that buffer is not accessible to the Windows paste command. You'll want to use the Edit | Copy and Edit | Paste (or their keyboard equivalents) if you're using the Windows GUI, or select with your mouse and use your X-Windows cut-n-paste mouse buttons if you're running UNIX.


Double-quote and star gives one access to windows clippboard or the unix equivalent. as an example if I wanted to yank the current line into the clipboard I would type "*yy

If I wanted to paste the contents of the clippboard into Vim at my current curser location I would type "*p

The double-qoute and start trick work well with visual mode as well. ex: visual select text to copy to clippboard and then type "*y

I find this very useful and I use it all the time but it is a bit slow typing "* all the time so I am thinking about creating a macro to speed it up a bit.


Copy and Paste using the System Clipboard

There are some caveats regarding how the "*y (copy into System Clipboard) command works. We have to be sure that we are using vim-full (sudo aptitude install vim-full on debian-based systems) or a Vim that has X11 support enabled. Only then will the "*y command work.

For our convenience as we are all familiar with using Ctrl+c to copy a block of text in most other GUI applications, we can also map Ctrl+c to "*y so that in Vim Visual Mode, we can simply Ctrl+c to copy the block of text we want into our system buffer. To do that, we simply add this line in our .vimrc file:

map <C-c> "+y<CR>

Restart our shell and we are good. Now whenever we are in Visual Mode, we can Ctrl+c to grab what we want and paste it into another application or another editor in a convenient and intuitive manner.

[Oct 21, 2018] Common visual block selection scenarios

Notable quotes:
"... column oriented ..."
Oct 21, 2018 | stackoverflow.com
You are talking about text selecting and copying, I think that you should give a look to the Vim Visual Mode .

In the visual mode, you are able to select text using Vim commands, then you can do whatever you want with the selection.

Consider the following common scenarios:

You need to select to the next matching parenthesis.

You could do:

You want to select text between quotes:

You want to select a curly brace block (very common on C-style languages):

You want to select the entire file:

Visual block selection is another really useful feature, it allows you to select a rectangular area of text, you just have to press Ctrl - V to start it, and then select the text block you want and perform any type of operation such as yank, delete, paste, edit, etc. It's great to edit column oriented text.

Notable quotes:
"... "send the line I am on (or the test I selected) to the other window" ..."
Oct 21, 2018 | superuser.com

brad ,Nov 24, 2015 at 12:28

I have two files, say a.txt and b.txt , in the same session of vim and I split the screen so I have file a.txt in the upper window and b.txt in the lower window.

I want to move lines here and there from a.txt to b.txt : I select a line with Shift + v , then I move to b.txt in the lower window with Ctrl + w , paste with p , get back to a.txt with Ctrl + w and I can repeat the operation when I get to another line I want to move.

My question: is there a quicker way to say vim "send the line I am on (or the test I selected) to the other window" ?

Anthony Geoghegan ,Nov 24, 2015 at 13:00

I presume that you're deleting the line that you've selected in a.txt . If not, you'd be pasting something else into b.txt . If so, there's no need to select the line first. – Anthony Geoghegan Nov 24 '15 at 13:00

Anthony Geoghegan ,Nov 24, 2015 at 13:17

This sounds like a good use case for a macro. Macros are commands that can be recorded and stored in a Vim register. Each register is identified by a letter from a to z. Recording

From Recording keys for repeated jobs - Vim Tips

To start recording, press q in Normal mode followed by a letter (a to z). That starts recording keystrokes to the specified register. Vim displays "recording" in the status line. Type any Normal mode commands, or enter Insert mode and type text. To stop recording, again press q while in Normal mode.

For this particular macro, I chose the m (for move) register to store it.

I pressed qm to record the following commands:

When I typed q to finish recording the macro, the contents of the m register were:

dd^Wjp^Wk

@romainl, yes, I know this but vim documentation is really huge and, although it doesn't scare me, there is always the possibility to miss something. Moreover, it could also be that you can obtain the effect using the combination of 2 commands and in this case it would be hardly documented – brad Nov 26 '15 at 10:17

[Oct 21, 2018] How to move around buffers in vim?

Oct 21, 2018 | stackoverflow.com

user3721893 ,Jul 23, 2014 at 5:43

I normally work with more than 5 files at a time. I use buffers to open different files. I use commands such as :buf file1, :buf file2 etc. Is there a faster way to move to different files?

eckes ,Jul 23, 2014 at 5:49

What I use:

And have a short look on :he buffer

And the wiki entry on Easier Buffer Switching on the Vim Wiki: http://vim.wikia.com/wiki/Easier_buffer_switching

SO already has a question regarding yours: How do you prefer to switch between buffers in Vim?

romainl ,Jul 23, 2014 at 6:13

A few mappings can make your life a lot easier.

This one lists your buffers and prompts you for a number:

nnoremap gb :buffers<CR>:buffer<Space>

This one lists your buffers in the "wildmenu". Depends on the 'wildcharm' option as well as 'wildmenu' and 'wildmode' :

nnoremap <leader>b :buffer <C-z>

These ones allow you to cycle between all your buffers without much thinking:

nnoremap <PageUp>   :bprevious<CR>
nnoremap <PageDown> :bnext<CR>

Also, don't forget <C-^> which allows you to alternate between two buffers.

mikew ,Jul 23, 2014 at 6:38

Once the buffers are already open, you can just type :b partial_filename to switch

So if :ls shows that i have my ~./vimrc open, then I can just type :b vimr or :b rc to switch to that buffer

Brady Trainor ,Jul 25, 2014 at 22:13

Below I describe some excerpts from sections of my .vimrc . It includes mapping the leader key, setting wilds tab completion, and finally my buffer nav key choices (all mostly inspired by folks on the interweb, including romainl). Edit: Then I ramble on about my shortcuts for windows and tabs.
" easier default keys {{{1

let mapleader=','
nnoremap <leader>2 :@"<CR>

The leader key is a prefix key for mostly user-defined key commands (some plugins also use it). The default is \ , but many people suggest the easier to reach , .

The second line there is a command to @ execute from the " clipboard, in case you'd like to quickly try out various key bindings (without relying on :so % ). (My nmeumonic is that Shift - 2 is @ .)

" wilds {{{1

set wildmenu wildmode=list:full
set wildcharm=<C-z>
set wildignore+=*~ wildignorecase

For built-in completion, wildmenu is probably the part that shows up yellow on your Vim when using tab completion on command-line. wildmode is set to a comma-separated list, each coming up in turn on each tab completion (that is, my list is simply one element, list:full ). list shows rows and columns of candidates. full 's meaning includes maintaining existence of the wildmenu . wildcharm is the way to include Tab presses in your macros. The *~ is for my use in :edit and :find commands.

" nav keys {{{1
" windows, buffers and tabs {{{2
" buffers {{{3

nnoremap <leader>bb :b <C-z><S-Tab>
nnoremap <leader>bh :ls!<CR>:b<Space>
nnoremap <leader>bw :ls!<CR>:bw<Space>
nnoremap <leader>bt :TSelectBuffer<CR>
nnoremap <leader>be :BufExplorer<CR>
nnoremap <leader>bs :BufExplorerHorizontalSplit<CR>
nnoremap <leader>bv :BufExplorerVerticalSplit<CR>
nnoremap <leader>3 :e#<CR>
nmap <C-n> :bn<cr>
nmap <C-p> :bp<cr>

The ,3 is for switching between the "two" last buffers (Easier to reach than built-in Ctrl - 6 ). Nmeuonic is Shift - 3 is # , and # is the register symbol for last buffer. (See :marks .)

,bh is to select from hidden buffers ( ! ).

,bw is to bwipeout buffers by number or name. For instance, you can wipeout several while looking at the list, with ,bw 1 3 4 8 10 <CR> . Note that wipeout is more destructive than :bdelete . They have their pros and cons. For instance, :bdelete leaves the buffer in the hidden list, while :bwipeout removes global marks (see :help marks , and the description of uppercase marks).

I haven't settled on these keybindings, I would sort of prefer that my ,bb was simply ,b (simply defining while leaving the others defined makes Vim pause to see if you'll enter more).

Those shortcuts for :BufExplorer are actually the defaults for that plugin, but I have it written out so I can change them if I want to start using ,b without a hang.

You didn't ask for this:

If you still find Vim buffers a little awkward to use, try to combine the functionality with tabs and windows (until you get more comfortable?).

" windows {{{3

" window nav
nnoremap <leader>w <C-w>
nnoremap <M-h> <C-w>h
nnoremap <M-j> <C-w>j
nnoremap <M-k> <C-w>k
nnoremap <M-l> <C-w>l
" resize window
nnoremap <C-h> <C-w><
nnoremap <C-j> <C-w>+
nnoremap <C-k> <C-w>-
nnoremap <C-l> <C-w>>

Notice how nice ,w is for a prefix. Also, I reserve Ctrl key for resizing, because Alt ( M- ) is hard to realize in all environments, and I don't have a better way to resize. I'm fine using ,w to switch windows.

" tabs {{{3

nnoremap <leader>t :tab
nnoremap <M-n> :tabn<cr>
nnoremap <M-p> :tabp<cr>
nnoremap <C-Tab> :tabn<cr>
nnoremap <C-S-Tab> :tabp<cr>
nnoremap tn :tabe<CR>
nnoremap te :tabe<Space><C-z><S-Tab>
nnoremap tf :tabf<Space>
nnoremap tc :tabc<CR>
nnoremap to :tabo<CR>
nnoremap tm :tabm<CR>
nnoremap ts :tabs<CR>

nnoremap th :tabr<CR>
nnoremap tj :tabn<CR>
nnoremap tk :tabp<CR>
nnoremap tl :tabl<CR>

" or, it may make more sense to use
" nnoremap th :tabp<CR>
" nnoremap tj :tabl<CR>
" nnoremap tk :tabr<CR>
" nnoremap tl :tabn<CR>

In summary of my window and tabs keys, I can navigate both of them with Alt , which is actually pretty easy to reach. In other words:

" (modifier) key choice explanation {{{3
"
"       KEYS        CTRL                  ALT            
"       hjkl        resize windows        switch windows        
"       np          switch buffer         switch tab      
"
" (resize windows is hard to do otherwise, so we use ctrl which works across
" more environments. i can use ',w' for windowcmds o.w.. alt is comfortable
" enough for fast and gui nav in tabs and windows. we use np for navs that 
" are more linear, hjkl for navs that are more planar.) 
"

This way, if the Alt is working, you can actually hold it down while you find your "open" buffer pretty quickly, amongst the tabs and windows.

,

There are many ways to solve. The best is the best that WORKS for YOU. You have lots of fuzzy match plugins that help you navigate. The 2 things that impress me most are

1) CtrlP or Unite's fuzzy buffer search

2) LustyExplorer and/or LustyJuggler

And the simplest :

:map <F5> :ls<CR>:e #

Pressing F5 lists all buffer, just type number.

The NERD tree allows you to explore your filesystem and to open files and directories. It presents the filesystem to you in the form of a tree which you manipulate with the keyboard and/or mouse. It also allows you to perform simple filesystem operations.

The tree can be toggled easily with :NERDTreeToggle which can be mapped to a more suitable key. The keyboard shortcuts in the NERD tree are also easy and intuitive.

  1. Elegant (mini) buffer explorer - This is the multiple file/buffer manager I use. Takes very little screen space. It looks just like most IDEs where you have a top tab-bar with the files you've opened. I've tested some other similar plugins before, and this is my pick.
  2. TagList - Small file explorer, without the "extra" stuff the other file explorers have. Just lets you browse directories and open files with the "enter" key. Note that this has already been noted by previous commenters to your questions.
  3. SuperTab - Already noted by WMR in this post, looks very promising. It's an auto-completion replacement key for Ctrl-P.
  4. Desert256 color Scheme - Readable, dark one.
  5. Moria color scheme - Another good, dark one. Note that it's gVim only.
  6. Enahcned Python syntax - If you're using Python, this is an enhanced syntax version. Works better than the original. I'm not sure, but this might be already included in the newest version. Nonetheless, it's worth adding to your syntax folder if you need it.
  7. Enhanced JavaScript syntax - Same like the above.

For vim I like a little help with completions. Vim has tons of completion modes, but really, I just want vim to complete anything it can, whenver it can.

I hate typing ending quotes, but fortunately this plugin obviates the need for such misery.

Those two are my heavy hitters.

This one may step up to roam my code like an unquiet shade, but I've yet to try it.

Txtfmt (The Vim Highlighter) Screenshots

The Txtfmt plugin gives you a sort of "rich text" highlighting capability, similar to what is provided by RTF editors and word processors. You can use it to add colors (foreground and background) and formatting attributes (all combinations of bold, underline, italic, etc...) to your plain text documents in Vim.

The advantage of this plugin over something like Latex is that with Txtfmt, your highlighting changes are visible "in real time", and as with a word processor, the highlighting is WYSIWYG. Txtfmt embeds special tokens directly in the file to accomplish the highlighting, so the highlighting is unaffected when you move the file around, even from one computer to another. The special tokens are hidden by the syntax; each appears as a single space. For those who have applied Vince Negri's conceal/ownsyntax patch, the tokens can even be made "zero-width".

P to paste the copied or deleted text before the current line

zelk, Mar 9, 2014 at 13:29

To copy two lines, it's even faster just to go yj or yk, especially since you don't double up on one character. Plus, yk is a backwards version that 2yy can't do, and you can put the number of lines to reach backwards in y9j or y2k, etc.. Only difference is that your count has to be n-1 for a total of n lines, but your head can learn that anyway. – zelk Mar 9 '14 at 13:29

DarkWiiPlayer, Apr 13 at 7:26

I know I'm late to the party, but whatever; I have this in my .vimrc:
nnoremap <C-d> :copy .<CR>
vnoremap <C-d> :copy '><CR>

the :copy command just copies the selected line or the range (always whole lines) to below the line number given as its argument.

In normal mode what this does is copy . copy this line to just below this line .

And in visual mode it turns into '<,'> copy '> copy from start of selection to end of selection to the line below end of selection .

yolenoyer, Apr 11 at 16:34

I like to use this mapping:
:nnoremap yp Yp

because it makes it consistent to use alongside the native YP command.

jedi, Feb 11 at 17:20

If you would like to duplicate a line and paste it right away below the current like, just like in Sublime Ctrl + Shift + D, then you can add this to your .vimrc file.

imap <S-C-d> <Esc>Yp

This works perfectly fine for me: imap <S-C-d> <Esc>Ypi insert mode and nmap <S-C-d> <Esc>Yp in normal mode – jedi Apr 14 at 17:48

For someone who doesn't know vi, some answers from above might mislead him with phrases like "paste ... after/before current line ".
It's actually "paste ... after/before cursor ".

yy or Y to copy the line
or
dd to delete the line

then

p to paste the copied or deleted text after the cursor
or
P to paste the copied or deleted text before the cursor

For those starting to learn vi, here is a good introduction to vi by listing side by side vi commands to typical Windows GUI Editor cursor movement and shortcut keys. It lists all the basic commands including yy (copy line) and p (paste after) or P (paste before).

vi (Vim) for Windows Users

pjz, Sep 16, 2008 at 15:04

yy

will yank the current line without deleting it

dd

will delete the current line

p

will put a line grabbed by either of the previous methods

Benoit, Apr 17, 2012 at 15:17

Normal mode: see other answers.

The Ex way:

If you need to move instead of copying, use :m instead of :t .

This can be really powerful if you combine it with :g or :v :

Reference: :help range, :help :t, :help :g, :help :m and :help :v

Benoit, Jun 30, 2012 at 14:17

When you press : in visual mode, it is transformed to '<,'> so it pre-selects the line range the visual selection spanned over. So, in visual mode, :t0 will copy the lines at the beginning. – Benoit Jun 30 '12 at 14:17

Niels Bom, Jul 31, 2012 at 8:21

For the record: when you type a colon (:) you go into command line mode where you can enter Ex commands. vimdoc.sourceforge.net/htmldoc/cmdline.html Ex commands can be really powerful and terse. The yyp solutions are "Normal mode" commands. If you want to copy/move/delete a far-away line or range of lines an Ex command can be a lot faster. – Niels Bom Jul 31 '12 at 8:21

Y is usually remapped to y$ (yank (copy) until end of line (from current cursor position, not beginning of line)) though. With this line in .vimrc : :nnoremap Y y$Aaron Thoma Aug 22 '13 at 23:31

Kwondri, Sep 16, 2008 at 15:37

If you want another way :-)

"ayy this will store the line in buffer a

"ap this will put the contents of buffer a at the cursor.

There are many variations on this.

"a5yy this will store the 5 lines in buffer a

Rook, Jul 14, 2009 at 4:37

Another option would be to go with:
nmap <C-d> mzyyp`z

gives you the advantage of preserving the cursor position.

,Sep 18, 2008 at 20:32

You can also try <C-x><C-l> which will repeat the last line from insert mode and brings you a completion window with all of the lines. It works almost like <C-p>

Jorge Gajon, May 11, 2009 at 6:38

This is very useful, but to avoid having to press many keys I have mapped it to just CTRL-L, this is my map: inoremap ^L ^X^L – Jorge Gajon May 11 '09 at 6:38

cori, Sep 16, 2008 at 15:06

1 gotcha: when you use "p" to put the line, it puts it after the line your cursor is on, so if you want to add the line after the line you're yanking, don't move the cursor down a line before putting the new line.

Ghoti, Jan 31, 2016 at 11:05

or use capital P - put before – Ghoti Jan 31 '16 at 11:05

[Oct 21, 2018] Indent multiple lines quickly in vi

Allain Lalonde, Oct 25, 2008 at 3:27

Should be trivial, and it might even be in the help, but I can't figure out how to navigate it. How do I indent multiple lines quickly in vi?

Greg Hewgill, Oct 25, 2008 at 3:28

Use the > command. To indent 5 lines, 5>> . To mark a block of lines and indent it, Vjj> to indent 3 lines (vim only). To indent a curly-braces block, put your cursor on one of the curly braces and use >% .

If you're copying blocks of text around and need to align the indent of a block in its new location, use ]p instead of just p . This aligns the pasted block with the surrounding text.

Also, the shiftwidth setting allows you to control how many spaces to indent.

akdom, Oct 25, 2008 at 3:31

<shift>-v also works to select a line in Vim. – akdom Oct 25 '08 at 3:31

Michael Ekoka, Feb 15, 2009 at 5:42

When you select a block and use > to indent, it indents then goes back to normal mode. I have this in my .vimrc file:
vnoremap < <gv

vnoremap > >gv

It lets you indent your selection as many time as you want.

sundar, Sep 1, 2009 at 17:14

To indent the selection multiple times, you can simply press . to repeat the previous command. – sundar Sep 1 '09 at 17:14

masukomi, Dec 6, 2013 at 21:24

The problem with . in this situation is that you have to move your fingers. With @mike's solution (same one i use) you've already got your fingers on the indent key and can just keep whacking it to keep indenting rather than switching and doing something else. Using period takes longer because you have to move your hands and it requires more thought because it's a second, different, operation. – masukomi Dec 6 '13 at 21:24

Johan, Jan 20, 2009 at 21:11

A big selection would be:
gg=G

It is really fast, and everything gets indented ;-)

This is not a uni-tasker. It works:

oligofren, Mar 27 at 15:23

This is cumbersome, but is the way to go if you do formatting outside of core VIM (for instance, using vim-prettier instead of the default indenting engine). Using > will otherwise royally scew up the formatting done by Prettier. – oligofren Mar 27 at 15:23

sqqqrly, Jun 15 at 16:30

Funny, I find it anything but cumbersome. This is not a uni-tasker! Learning this method has many uses beyond indenting. – sqqqrly Jun 15 at 16:30

user4052054, Aug 17 at 17:50

I find it better than the accepted answer, as I can see what is happening, the lines I'm selecting and the action I'm doing, and not just type some sort of vim incantation. – user4052054 Aug 17 at 17:50

Sergio, Apr 25 at 7:14

Suppose | represents the position of the cursor in Vim. If the text to be indented is enclosed in a code block like:
int main() {
line1
line2|
line3
}

you can do >i{ which means " indent ( > ) inside ( i ) block ( { ) " and get:

int main() {
    line1
    line2|
    line3
}

Now suppose the lines are contiguous but outside a block, like:

do
line2|
line3
line4
done

To indent lines 2 thru 4 you can visually select the lines and type > . Or even faster you can do >2j to get:

do
    line2|
    line3
    line4
done

Note that >Nj means indent from current line to N lines below. If the number of lines to be indented is large, it could take some seconds for the user to count the proper value of N . To save valuable seconds you can activate the option of relative number with set relativenumber (available since Vim version 7.3).

Sagar Jain, Apr 18, 2014 at 18:41

The master of all commands is
gg=G

This indents the entire file!

And below are some of the simple and elegant commands used to indent lines quickly in Vim or gVim.

To indent the current line
==

To indent the all the lines below the current line

=G

To indent n lines below the current line

n==

For example, to indent 4 lines below the current line

4==

To indent a block of code, go to one of the braces and use command

=%

These are the simplest, yet powerful commands to indent multiple lines.

zundarz, Sep 10, 2015 at 18:41

:help left

In ex mode you can use :left or :le to align lines a specified amount. Specifically, :left will Left align lines in the [range]. It sets the indent in the lines to [indent] (default 0).

:%le3 or :%le 3 or :%left3 or :%left 3 will align the entire file by padding with three spaces.

:5,7 le 3 will align lines 5 through 7 by padding them with 3 spaces.

:le without any value or :le 0 will left align with a padding of 0.

This works in vim and gvim .

Subfuzion, Aug 11, 2017 at 22:02

Awesome, just what I was looking for (a way to insert a specific number of spaces -- 4 spaces for markdown code -- to override my normal indent). In my case I wanted to indent a specific number of lines in visual mode, so shift-v to highlight the lines, then :'<,'>le4 to insert the spaces. Thanks! – Subfuzion Aug 11 '17 at 22:02

Nykakin, Aug 21, 2015 at 13:33

There is one more way that hasn't been mentioned yet - you can use norm i command to insert given text at the beginning of the line. To insert 10 spaces before lines 2-10:
:2,10norm 10i

Remember that there has to be space character at the end of the command - this will be the character we want to have inserted. We can also indent line with any other text, for example to indent every line in file with 5 underscore characters:

:%norm 5i_

Or something even more fancy:

:%norm 2i[ ]

More practical example is commenting Bash/Python/etc code with # character:

:1,20norm i#

To re-indent use x instead of i . For example to remove first 5 characters from every line:

:%norm 5x

Eliethesaiyan, Jun 13, 2016 at 14:18

this starts from the left side of the file...not the the current position of the block – Eliethesaiyan Jun 13 '16 at 14:18

John Sonderson, Jan 31, 2015 at 19:17

Suppose you use 2 spaces to indent your code. Type:
:set shiftwidth=2

Then:

You get the idea.

( Empty lines will not get indented, which I think is kind of nice. )


I found the answer in the (g)vim documentation for indenting blocks:

:help visual-block
/indent

If you want to give a count to the command, do this just before typing the operator character: "v{move-around}3>" (move lines 3 indents to the right).

Michael, Dec 19, 2014 at 20:18

To indent all file by 4:
esc 4G=G

underscore_d, Oct 17, 2015 at 19:35

...what? 'indent by 4 spaces'? No, this jumps to line 4 and then indents everything from there to the end of the file, using the currently selected indent mode (if any). – underscore_d Oct 17 '15 at 19:35

Abhishesh Sharma, Jul 15, 2014 at 9:22

:line_num_start,line_num_end>

Increase the '>' symbol for more tabs

e.g.

14,21>>> for 3 tabs

HoldOffHunger, Dec 5, 2017 at 15:50

There are clearly a lot of ways to solve this, but this is the easiest to implement, as line numbers show by default in vim and it doesn't require math. – HoldOffHunger Dec 5 '17 at 15:50

rohitkadam19, May 7, 2013 at 7:13

5== will indent 5 lines from current cursor position. so you can type any number before ==, it will indent number of lines. This is in command mode.

gg=G will indent whole file from top to bottom.

Kamlesh Karwande, Feb 6, 2014 at 4:04

I dont know why its so difficult to find a simple answer like this one...

I myself had to struggle a lot to know this its its very simple

edit your .vimrc file under home directory add this line

set cindent

in you file where you want to indent properly

in normal/command mode type

10==   (this will indent 10 lines from the current cursor location )
gg=G   (complete file will be properly indented)

How to indent highlighted code in vi immediately by a # of spaces:

Option 1: Indent a block of code in vi to three spaces with Visual Block mode:

  1. Select the block of code you want to indent. Do this using Ctrl+V in normal mode and arrowing down to select text. While it is selected, enter : to give a command to the block of selected text.
  2. The following will appear in the command line: :'<,'>
  3. To set indent to 3 spaces, type le 3 and press enter. This is what appears: :'<,'>le 3
  4. The selected text is immediately indented to 3 spaces.

Option 2: Indent a block of code in vi to three spaces with Visual Line mode:

  1. Open your file in VI.
  2. Put your cursor over some code
  3. Be in normal mode press the following keys:
    Vjjjj:le 3
    

    Interpretation of what you did:

    V means start selecting text.

    jjjj arrows down 4 lines, highlighting 4 lines.

    : tells vi you will enter an instruction for the highlighted text.

    le 3 means indent highlighted text 3 lines.

    The selected code is immediately increased or decreased to three spaces indentation.

Option 3: use Visual Block mode and special insert mode to increase indent:

  1. Open your file in VI.
  2. Put your cursor over some code
  3. Be in normal mode press the following keys:

    Ctrl+V

    jjjj
    

    (press spacebar 5 times)

    Esc Shift+i

    All the highlighted text is indented an additional 5 spaces.

ire_and_curses, Mar 6, 2011 at 17:29

This answer summarises the other answers and comments of this question, and adds extra information based on the Vim documentation and the Vim wiki . For conciseness, this answer doesn't distinguish between Vi and Vim-specific commands.

In the commands below, "re-indent" means "indent lines according to your indentation settings ." shiftwidth is the primary variable that controls indentation.

General Commands

>>   Indent line by shiftwidth spaces
<<   De-indent line by shiftwidth spaces
5>>  Indent 5 lines
5==  Re-indent 5 lines

>%   Increase indent of a braced or bracketed block (place cursor on brace first)
=%   Reindent a braced or bracketed block (cursor on brace)
<%   Decrease indent of a braced or bracketed block (cursor on brace)
]p   Paste text, aligning indentation with surroundings

=i{  Re-indent the 'inner block', i.e. the contents of the block
=a{  Re-indent 'a block', i.e. block and containing braces
=2a{ Re-indent '2 blocks', i.e. this block and containing block

>i{  Increase inner block indent
<i{  Decrease inner block indent

You can replace { with } or B, e.g. =iB is a valid block indent command. Take a look at "Indent a Code Block" for a nice example to try these commands out on.

Also, remember that

.    Repeat last command

, so indentation commands can be easily and conveniently repeated.

Re-indenting complete files

Another common situation is requiring indentation to be fixed throughout a source file:

gg=G  Re-indent entire buffer

You can extend this idea to multiple files:

" Re-indent all your c source code:
:args *.c
:argdo normal gg=G
:wall

Or multiple buffers:

" Re-indent all open buffers:
:bufdo normal gg=G:wall

In Visual Mode

Vjj> Visually mark and then indent 3 lines

In insert mode

These commands apply to the current line:

CTRL-t   insert indent at start of line
CTRL-d   remove indent at start of line
0 CTRL-d remove all indentation from line

Ex commands

These are useful when you want to indent a specific range of lines, without moving your cursor.

:< and :> Given a range, apply indentation e.g.
:4,8>   indent lines 4 to 8, inclusive

Indenting using markers

Another approach is via markers :

ma     Mark top of block to indent as marker 'a'

...move cursor to end location

>'a    Indent from marker 'a' to current location

Variables that govern indentation

You can set these in your .vimrc file .

set expandtab       "Use softtabstop spaces instead of tab characters for indentation
set shiftwidth=4    "Indent by 4 spaces when using >>, <<, == etc.
set softtabstop=4   "Indent by 4 spaces when pressing <TAB>

set autoindent      "Keep indentation from previous line
set smartindent     "Automatically inserts indentation in some cases
set cindent         "Like smartindent, but stricter and more customisable

Vim has intelligent indentation based on filetype. Try adding this to your .vimrc:

if has ("autocmd")
    " File type detection. Indent based on filetype. Recommended.
    filetype plugin indent on
endif

Both this answer and the one above it were great. But I +1'd this because it reminded me of the 'dot' operator, which repeats the last command. This is extremely useful when needing to indent an entire block several shiftspaces (or indentations) without needing to keep pressing >} . Thanks a long – Amit Aug 10 '11 at 13:26

5>> Indent 5 lines : This command indents the fifth line, not 5 lines. Could this be due to my VIM settings, or is your wording incorrect? – Wipqozn Aug 24 '11 at 16:00

ire_and_curses, Aug 24, 2011 at 16:21

@Wipqozn - That's strange. It definitely indents the next five lines for me, tested on Vim 7.2.330. – ire_and_curses Aug 24 '11 at 16:21

Great summary! Also note that the "indent inside block" and "indent all block" (<i{ >a{ etc.) also works with parentheses and brackets: >a( <i] etc. (And while I'm at it, in addition to <>'s, they also work with d,c,y etc.) – aqn Mar 6 '13 at 4:42

I didn't find a method I use in the comments, so I'll share it (I think vim only):
  1. Esc to enter command mode
  2. Move to the first character of the last line you want to ident
  3. ctrl - v to start block select
  4. Move to the first character of the first line you want to ident
  5. shift - i to enter special insert mode
  6. type as many spases/tabs as you need to indent to (2 for example
  7. press Esc and spaces will appear in all lines

This is useful when you don't want to change ident/tab settings in vimrc or to remember them to change it while editing.

To unindent I use the same ctrl - v block select to select spaces and delete it with d .

svec, Oct 25, 2008 at 4:21

Also try this for C-indenting indentation, do :help = for more info:

={

That will auto-indent the current code block you're in.

Or just:

==

to auto-indent the current line.

underscore_d, Oct 17, 2015 at 19:39

John La Rooy, Jul 2, 2013 at 7:24

Using Python a lot, I find myself needing frequently needing to shift blocks by more than one indent. You can do this by using any of the block selection methods, and then just enter the number of indents you wish to jump right before the >

Eg. V5j3> will indent 5 lines 3 times - which is 12 spaces if you use 4 spaces for indents

Juan Lanus, Sep 18, 2012 at 14:12

The beauty of vim's UI is that it's consistent. Editing commands are made up of the command and a cursor move. The cursor moves are always the same:

So, in order to use vim you have to learn to move the cursor and remember a repertoire of commands like, for example, > to indent (and < to "outdent").
Thus, for indenting the lines from the cursor position to the top of the screen you do >H, >G to indent to the bottom of the file.

If, instead of typing >H, you type dH then you are deleting the same block of lines, cH for replacing it, etc.

Some cursor movements fit better with specific commands. In particular, the % command is handy to indent a whole HTML or XML block.
If the file has syntax highlighted ( :syn on ) then setting the cursor in the text of a tag (like, in the "i" of <div> and entering >% will indent up to the closing </div> tag.

This is how vim works: one has to remember only the cursor movements and the commands, and how to mix them.
So my answer to this question would be "go to one end of the block of lines you want to indent, and then type the > command and a movement to the other end of the block" if indent is interpreted as shifting the lines, = if indent is interpreted as in pretty-printing.

aqn, Mar 6, 2013 at 4:38

I would say that vi/vim is mostly consistent. For instance, D does not behave the same as S and Y! :) – aqn Mar 6 '13 at 4:38

Key-Presses for more visual people:
  1. Enter Command Mode:
    Escape
  2. Move around to the start of the area to indent:
    hjkl↑↓←→
  3. Start a block:
    v
  4. Move around to the end of the area to indent:
    hjkl↑↓←→
  5. (Optional) Type the number of indentation levels you want
    0..9
  6. Execute the indentation on the block:
    >

Shane Reustle, Mar 10, 2011 at 22:24

This is great, but it uses spaces and not tabs. Any possible way to fix this? – Shane Reustle Mar 10 '11 at 22:24

Kent Fredric, Mar 16, 2011 at 8:33

If its using spaces instead of tabs, then its probably because you have indentation set to use spaces. =). – Kent Fredric Mar 16 '11 at 8:33

Kent Fredric, Mar 16, 2011 at 8:36

When the 'expandtab' option is off (this is the default) Vim uses <Tab>s as much as possible to make the indent. ( :help :> ) – Kent Fredric Mar 16 '11 at 8:36

Shane Reustle, Dec 2, 2012 at 3:17

The only tab/space related vim setting I've changed is :set tabstop=3. It's actually inserting this every time I use >>: "<tab><space><space>". Same with indenting a block. Any ideas? – Shane Reustle Dec 2 '12 at 3:17

Kent Fredric, Dec 2, 2012 at 17:08

The three settings you want to look at for "spaces vs tabs" are 1. tabstop 2. shiftwidth 3. expandtab. You probably have "shiftwidth=5 noexpandtab", so a "tab" is 3 spaces, and an indentation level is "5" spaces, so it makes up the 5 with 1 tab, and 2 spaces. – Kent Fredric Dec 2 '12 at 17:08

mda, Jun 4, 2012 at 5:12

For me, the MacVim (Visual) solution was, select with mouse and press ">", but after putting the following lines in "~/.vimrc" since I like spaces instead of tabs:
set expandtab
set tabstop=2
set shiftwidth=2

Also it's useful to be able to call MacVim from the command-line (Terminal.app), so since I have the following helper directory "~/bin", where I place a script called "macvim":

#!/usr/bin/env bash
/usr/bin/open -a /Applications/MacPorts/MacVim.app $@

And of course in "~/.bashrc":

export PATH=$PATH:$HOME/bin

Macports messes with "~/.profile" a lot, so the PATH environment variable can get quite long.

>} or >{ indent from current line up to next paragraph

<} or <{ same un-indent

Eric Kigathi, Jan 4, 2012 at 0:41

A quick way to do this using VISUAL MODE uses the same process as commenting a block of code.

This is useful if you would prefer not to change your shiftwidth or use any set directives and is flexible enough to work with TABS or SPACES or any other character.

  1. Position cursor at the beginning on the block
  2. v to switch to -- VISUAL MODE --
  3. Select the text to be indented
  4. Type : to switch to the prompt
  5. Replacing with 3 leading spaces:

    :'<,'>s/^/ /g

  6. Or replacing with leading tabs:

    :'<,'>s/^/\t/g

  7. Brief Explanation:

    '<,'> - Within the Visually Selected Range

    s/^/ /g - Insert 3 spaces at the beginning of every line within the whole range

    (or)

    s/^/\t/g - Insert Tab at the beginning of every line within the whole range

pankaj ukumar, Nov 11, 2009 at 17:33

do this
$vi .vimrc

and add this line

autocmd FileType cpp setlocal expandtab shiftwidth=4 softtabstop=4 cindent

this is only for cpp file you can do this for another file type also just by modifying the filetype...

SteveO, Nov 10, 2010 at 19:16

I like to mark text for indentation:
  1. go to beginning of line of text then type ma (a is the label from the 'm'ark: it could be any letter)
  2. go to end line of text and type mz (again z could be any letter)
  3. :'a,'z> or :'a,'z< will indent or outdent (is this a word?)
  4. Voila! the text is moved (empty lines remain empty with no spaces)

PS: you can use :'a,'z technique to mark a range for any operation (d,y,s///, etc) where you might use lines, numbers, or %

Paul Tomblin, Oct 25, 2008 at 4:08

As well as the offered solutions, I like to do things a paragraph at a time with >}

aqn, Mar 6, 2013 at 4:47

Yup, and this is why one of my big peeves is white spaces on an otherwise empty line: they messes up vim's notion of a "paragraph". – aqn Mar 6 '13 at 4:47

Daniel Spiewak, Oct 25, 2008 at 4:00

In addition to the answer already given and accepted, it is also possible to place a marker and then indent everything from the current cursor to the marker. Thus, enter ma where you want the top of your indented block, cursor down as far as you need and then type >'a (note that " a " can be substituted for any valid marker name). This is sometimes easier than 5>> or vjjj> .

user606723, Mar 17, 2011 at 15:31

This is really useful. I am going to have to look up what all works with this. I know d'a and y'a, what else? – user606723 Mar 17 '11 at 15:31

ziggy, Aug 25, 2014 at 14:14

This is very useful as it avoids the need to count how many lines you want to indent. – ziggy Aug 25 '14 at 14:14

You should use blockwise visual mode ( Ctrl + v ). Then d to delete block, p or P to paste block.

One of the few useful command I learned at the beginning of learning VIM is :1,3 mo 5 This means move text line 1 through 3 to line 5.

Júda Ronén ,Jan 18, 2017 at 21:20

And you can select the lines in visual mode, then press : to get :'<,'> (equivalent to the :1,3 part in your answer), and add mo N . If you want to move a single line, just :mo N . If you are really lazy, you can omit the space (e.g. :mo5 ). Use marks with mo '{a-zA-Z} . – Júda Ronén Jan 18 '17 at 21:20

  1. In VIM, press Ctrl + V to go in Visual Block mode
  2. Select the required columns with your arrow keys and press x to cut them in the buffer.
  3. Move cursor to row 1 column 9 and press P (thats capital P) in command mode.
  4. Press Ctrl + Shift + b to get in and out of it. ( source )

[Oct 21, 2018] What is your most productive shortcut with Vim?

Notable quotes:
"... less productive ..."
"... column oriented ..."
Feb 17, 2013 | stackoverflow.com
I've heard a lot about Vim, both pros and cons. It really seems you should be (as a developer) faster with Vim than with any other editor. I'm using Vim to do some basic stuff and I'm at best 10 times less productive with Vim.

The only two things you should care about when you talk about speed (you may not care enough about them, but you should) are:

  1. Using alternatively left and right hands is the fastest way to use the keyboard.
  2. Never touching the mouse is the second way to be as fast as possible. It takes ages for you to move your hand, grab the mouse, move it, and bring it back to the keyboard (and you often have to look at the keyboard to be sure you returned your hand properly to the right place)

Here are two examples demonstrating why I'm far less productive with Vim.

Copy/Cut & paste. I do it all the time. With all the contemporary editors you press Shift with the left hand, and you move the cursor with your right hand to select text. Then Ctrl + C copies, you move the cursor and Ctrl + V pastes.

With Vim it's horrible:

Another example? Search & replace.

And everything with Vim is like that: it seems I don't know how to handle it the right way.

NB : I've already read the Vim cheat sheet :)

My question is: What is the way you use Vim that makes you more productive than with a contemporary editor?

community wiki 18 revs, 16 users 64%, Dec 22, 2011 at 11:43

Your problem with Vim is that you don't grok vi .

You mention cutting with yy and complain that you almost never want to cut whole lines. In fact programmers, editing source code, very often want to work on whole lines, ranges of lines and blocks of code. However, yy is only one of many way to yank text into the anonymous copy buffer (or "register" as it's called in vi ).

The "Zen" of vi is that you're speaking a language. The initial y is a verb. The statement yy is a synonym for y_ . The y is doubled up to make it easier to type, since it is such a common operation.

This can also be expressed as dd P (delete the current line and paste a copy back into place; leaving a copy in the anonymous register as a side effect). The y and d "verbs" take any movement as their "subject." Thus yW is "yank from here (the cursor) to the end of the current/next (big) word" and y'a is "yank from here to the line containing the mark named ' a '."

If you only understand basic up, down, left, and right cursor movements then vi will be no more productive than a copy of "notepad" for you. (Okay, you'll still have syntax highlighting and the ability to handle files larger than a piddling ~45KB or so; but work with me here).

vi has 26 "marks" and 26 "registers." A mark is set to any cursor location using the m command. Each mark is designated by a single lower case letter. Thus ma sets the ' a ' mark to the current location, and mz sets the ' z ' mark. You can move to the line containing a mark using the ' (single quote) command. Thus 'a moves to the beginning of the line containing the ' a ' mark. You can move to the precise location of any mark using the ` (backquote) command. Thus `z will move directly to the exact location of the ' z ' mark.

Because these are "movements" they can also be used as subjects for other "statements."

So, one way to cut an arbitrary selection of text would be to drop a mark (I usually use ' a ' as my "first" mark, ' z ' as my next mark, ' b ' as another, and ' e ' as yet another (I don't recall ever having interactively used more than four marks in 15 years of using vi ; one creates one's own conventions regarding how marks and registers are used by macros that don't disturb one's interactive context). Then we go to the other end of our desired text; we can start at either end, it doesn't matter. Then we can simply use d`a to cut or y`a to copy. Thus the whole process has a 5 keystrokes overhead (six if we started in "insert" mode and needed to Esc out command mode). Once we've cut or copied then pasting in a copy is a single keystroke: p .

I say that this is one way to cut or copy text. However, it is only one of many. Frequently we can more succinctly describe the range of text without moving our cursor around and dropping a mark. For example if I'm in a paragraph of text I can use { and } movements to the beginning or end of the paragraph respectively. So, to move a paragraph of text I cut it using { d} (3 keystrokes). (If I happen to already be on the first or last line of the paragraph I can then simply use d} or d{ respectively.

The notion of "paragraph" defaults to something which is usually intuitively reasonable. Thus it often works for code as well as prose.

Frequently we know some pattern (regular expression) that marks one end or the other of the text in which we're interested. Searching forwards or backwards are movements in vi . Thus they can also be used as "subjects" in our "statements." So I can use d/foo to cut from the current line to the next line containing the string "foo" and y?bar to copy from the current line to the most recent (previous) line containing "bar." If I don't want whole lines I can still use the search movements (as statements of their own), drop my mark(s) and use the `x commands as described previously.

In addition to "verbs" and "subjects" vi also has "objects" (in the grammatical sense of the term). So far I've only described the use of the anonymous register. However, I can use any of the 26 "named" registers by prefixing the "object" reference with " (the double quote modifier). Thus if I use "add I'm cutting the current line into the ' a ' register and if I use "by/foo then I'm yanking a copy of the text from here to the next line containing "foo" into the ' b ' register. To paste from a register I simply prefix the paste with the same modifier sequence: "ap pastes a copy of the ' a ' register's contents into the text after the cursor and "bP pastes a copy from ' b ' to before the current line.

This notion of "prefixes" also adds the analogs of grammatical "adjectives" and "adverbs' to our text manipulation "language." Most commands (verbs) and movement (verbs or objects, depending on context) can also take numeric prefixes. Thus 3J means "join the next three lines" and d5} means "delete from the current line through the end of the fifth paragraph down from here."

This is all intermediate level vi . None of it is Vim specific and there are far more advanced tricks in vi if you're ready to learn them. If you were to master just these intermediate concepts then you'd probably find that you rarely need to write any macros because the text manipulation language is sufficiently concise and expressive to do most things easily enough using the editor's "native" language.


A sampling of more advanced tricks:

There are a number of : commands, most notably the :% s/foo/bar/g global substitution technique. (That's not advanced but other : commands can be). The whole : set of commands was historically inherited by vi 's previous incarnations as the ed (line editor) and later the ex (extended line editor) utilities. In fact vi is so named because it's the visual interface to ex .

: commands normally operate over lines of text. ed and ex were written in an era when terminal screens were uncommon and many terminals were "teletype" (TTY) devices. So it was common to work from printed copies of the text, using commands through an extremely terse interface (common connection speeds were 110 baud, or, roughly, 11 characters per second -- which is slower than a fast typist; lags were common on multi-user interactive sessions; additionally there was often some motivation to conserve paper).

So the syntax of most : commands includes an address or range of addresses (line number) followed by a command. Naturally one could use literal line numbers: :127,215 s/foo/bar to change the first occurrence of "foo" into "bar" on each line between 127 and 215. One could also use some abbreviations such as . or $ for current and last lines respectively. One could also use relative prefixes + and - to refer to offsets after or before the curent line, respectively. Thus: :.,$j meaning "from the current line to the last line, join them all into one line". :% is synonymous with :1,$ (all the lines).

The :... g and :... v commands bear some explanation as they are incredibly powerful. :... g is a prefix for "globally" applying a subsequent command to all lines which match a pattern (regular expression) while :... v applies such a command to all lines which do NOT match the given pattern ("v" from "conVerse"). As with other ex commands these can be prefixed by addressing/range references. Thus :.,+21g/foo/d means "delete any lines containing the string "foo" from the current one through the next 21 lines" while :.,$v/bar/d means "from here to the end of the file, delete any lines which DON'T contain the string "bar."

It's interesting that the common Unix command grep was actually inspired by this ex command (and is named after the way in which it was documented). The ex command :g/re/p (grep) was the way they documented how to "globally" "print" lines containing a "regular expression" (re). When ed and ex were used, the :p command was one of the first that anyone learned and often the first one used when editing any file. It was how you printed the current contents (usually just one page full at a time using :.,+25p or some such).

Note that :% g/.../d or (its reVerse/conVerse counterpart: :% v/.../d are the most common usage patterns. However there are couple of other ex commands which are worth remembering:

We can use m to move lines around, and j to join lines. For example if you have a list and you want to separate all the stuff matching (or conversely NOT matching some pattern) without deleting them, then you can use something like: :% g/foo/m$ ... and all the "foo" lines will have been moved to the end of the file. (Note the other tip about using the end of your file as a scratch space). This will have preserved the relative order of all the "foo" lines while having extracted them from the rest of the list. (This would be equivalent to doing something like: 1G!GGmap!Ggrep foo<ENTER>1G:1,'a g/foo'/d (copy the file to its own tail, filter the tail through grep, and delete all the stuff from the head).

To join lines usually I can find a pattern for all the lines which need to be joined to their predecessor (all the lines which start with "^ " rather than "^ * " in some bullet list, for example). For that case I'd use: :% g/^ /-1j (for every matching line, go up one line and join them). (BTW: for bullet lists trying to search for the bullet lines and join to the next doesn't work for a couple reasons ... it can join one bullet line to another, and it won't join any bullet line to all of its continuations; it'll only work pairwise on the matches).

Almost needless to mention you can use our old friend s (substitute) with the g and v (global/converse-global) commands. Usually you don't need to do so. However, consider some case where you want to perform a substitution only on lines matching some other pattern. Often you can use a complicated pattern with captures and use back references to preserve the portions of the lines that you DON'T want to change. However, it will often be easier to separate the match from the substitution: :% g/foo/s/bar/zzz/g -- for every line containing "foo" substitute all "bar" with "zzz." (Something like :% s/\(.*foo.*\)bar\(.*\)/\1zzz\2/g would only work for the cases those instances of "bar" which were PRECEDED by "foo" on the same line; it's ungainly enough already, and would have to be mangled further to catch all the cases where "bar" preceded "foo")

The point is that there are more than just p, s, and d lines in the ex command set.

The : addresses can also refer to marks. Thus you can use: :'a,'bg/foo/j to join any line containing the string foo to its subsequent line, if it lies between the lines between the ' a ' and ' b ' marks. (Yes, all of the preceding ex command examples can be limited to subsets of the file's lines by prefixing with these sorts of addressing expressions).

That's pretty obscure (I've only used something like that a few times in the last 15 years). However, I'll freely admit that I've often done things iteratively and interactively that could probably have been done more efficiently if I'd taken the time to think out the correct incantation.

Another very useful vi or ex command is :r to read in the contents of another file. Thus: :r foo inserts the contents of the file named "foo" at the current line.

More powerful is the :r! command. This reads the results of a command. It's the same as suspending the vi session, running a command, redirecting its output to a temporary file, resuming your vi session, and reading in the contents from the temp. file.

Even more powerful are the ! (bang) and :... ! ( ex bang) commands. These also execute external commands and read the results into the current text. However, they also filter selections of our text through the command! This we can sort all the lines in our file using 1G!Gsort ( G is the vi "goto" command; it defaults to going to the last line of the file, but can be prefixed by a line number, such as 1, the first line). This is equivalent to the ex variant :1,$!sort . Writers often use ! with the Unix fmt or fold utilities for reformating or "word wrapping" selections of text. A very common macro is {!}fmt (reformat the current paragraph). Programmers sometimes use it to run their code, or just portions of it, through indent or other code reformatting tools.

Using the :r! and ! commands means that any external utility or filter can be treated as an extension of our editor. I have occasionally used these with scripts that pulled data from a database, or with wget or lynx commands that pulled data off a website, or ssh commands that pulled data from remote systems.

Another useful ex command is :so (short for :source ). This reads the contents of a file as a series of commands. When you start vi it normally, implicitly, performs a :source on ~/.exinitrc file (and Vim usually does this on ~/.vimrc, naturally enough). The use of this is that you can change your editor profile on the fly by simply sourcing in a new set of macros, abbreviations, and editor settings. If you're sneaky you can even use this as a trick for storing sequences of ex editing commands to apply to files on demand.

For example I have a seven line file (36 characters) which runs a file through wc, and inserts a C-style comment at the top of the file containing that word count data. I can apply that "macro" to a file by using a command like: vim +'so mymacro.ex' ./mytarget

(The + command line option to vi and Vim is normally used to start the editing session at a given line number. However it's a little known fact that one can follow the + by any valid ex command/expression, such as a "source" command as I've done here; for a simple example I have scripts which invoke: vi +'/foo/d|wq!' ~/.ssh/known_hosts to remove an entry from my SSH known hosts file non-interactively while I'm re-imaging a set of servers).

Usually it's far easier to write such "macros" using Perl, AWK, sed (which is, in fact, like grep a utility inspired by the ed command).

The @ command is probably the most obscure vi command. In occasionally teaching advanced systems administration courses for close to a decade I've met very few people who've ever used it. @ executes the contents of a register as if it were a vi or ex command.
Example: I often use: :r!locate ... to find some file on my system and read its name into my document. From there I delete any extraneous hits, leaving only the full path to the file I'm interested in. Rather than laboriously Tab -ing through each component of the path (or worse, if I happen to be stuck on a machine without Tab completion support in its copy of vi ) I just use:

  1. 0i:r (to turn the current line into a valid :r command),
  2. "cdd (to delete the line into the "c" register) and
  3. @c execute that command.

That's only 10 keystrokes (and the expression "cdd @c is effectively a finger macro for me, so I can type it almost as quickly as any common six letter word).


A sobering thought

I've only scratched to surface of vi 's power and none of what I've described here is even part of the "improvements" for which vim is named! All of what I've described here should work on any old copy of vi from 20 or 30 years ago.

There are people who have used considerably more of vi 's power than I ever will.

@Wahnfieden -- grok is exactly what I meant: en.wikipedia.org/wiki/Grok (It's apparently even in the OED --- the closest we anglophones have to a canonical lexicon).

Superb answer that utterly redeems a really horrible question. I am going to upvote this question, that normally I would downvote, just so that this answer becomes easier to find. (And I'm an Emacs guy! But this way I'll have somewhere to point new folks who want a good explanation of what vi power users find fun about vi. Then I'll tell them about Emacs and they can decide.) – Brandon Rhodes Mar 29 '10 at 15:26

You are talking about text selecting and copying, I think that you should give a look to the Vim Visual Mode .

In the visual mode, you are able to select text using Vim commands, then you can do whatever you want with the selection.

Consider the following common scenarios:

You need to select to the next matching parenthesis.

You could do:

You want to select text between quotes:

You want to select a curly brace block (very common on C-style languages):

You want to select the entire file:

Visual block selection is another really useful feature, it allows you to select a rectangular area of text, you just have to press Ctrl - V to start it, and then select the text block you want and perform any type of operation such as yank, delete, paste, edit, etc. It's great to edit column oriented text.

finnw, Aug 2, 2009 at 8:49

Every editor has something like this, it's not specific to vim. – finnw Aug 2 '09 at 8:49

guns, Aug 2, 2009 at 9:54

Yes, but it was a specific complaint of the poster. Visual mode is Vim's best method of direct text-selection and manipulation. And since vim's buffer traversal methods are superb, I find text selection in vim fairly pleasurable. – guns Aug 2 '09 at 9:54

Hamish Downer, Mar 16, 2010 at 13:34

I think it is also worth mentioning Ctrl-V to select a block - ie an arbitrary rectangle of text. When you need it it's a lifesaver. – Hamish Downer Mar 16 '10 at 13:34

Also, if you've got a visual selection and want to adjust it, o will hop to the other end. So you can move both the beginning and the end of the selection as much as you like. – Nathan Long Mar 1 '11 at 19:05

Some productivity tips:

Smart movements

Quick editing commands

Combining commands

Most commands accept a amount and direction, for example:

Useful programmer commands

Macro recording

By using very specific commands and movements, VIM can replay those exact actions for the next lines. (e.g. A for append-to-end, b / e to move the cursor to the begin or end of a word respectively)

Example of well built settings

# reset to vim-defaults
if &compatible          # only if not set before:
  set nocompatible      # use vim-defaults instead of vi-defaults (easier, more user friendly)
endif

# display settings

set nowrap              # dont wrap lines
set scrolloff=2         # 2 lines above/below cursor when scrolling
set number              # show line numbers
set showmatch           # show matching bracket (briefly jump)
set showmode            # show mode in status bar (insert/replace/...)
set showcmd             # show typed command in status bar
set ruler               # show cursor position in status bar
set title               # show file in titlebar
set wildmenu            # completion with menu
set wildignore=*.o,*.obj,*.bak,*.exe,*.py[co],*.swp,*~,*.pyc,.svn
set laststatus=2        # use 2 lines for the status bar
set matchtime=2         # show matching bracket for 0.2 seconds
set matchpairs+=<:>     # specially for html

# editor settings
set esckeys             # map missed escape sequences (enables keypad keys)
set ignorecase          # case insensitive searching
set smartcase           # but become case sensitive if you type uppercase characters
set smartindent         # smart auto indenting
set smarttab            # smart tab handling for indenting

set bs=indent,eol,start # Allow backspacing over everything in insert mode

set tabstop=4           # number of spaces a tab counts for
set shiftwidth=4        # spaces for autoindents
#set expandtab           # turn a tabs into spaces

  # Always jump to the last known cursor position. 
  # Don't do it when the position is invalid or when inside

  autocmd BufReadPost * 
    \ if line("'\"") > 0 && line("'\"") <= line("$") | 
    \   exe "normal g`\"" | 
    \ endif 

endif # has("autocmd")

The settings can be stored in ~/.vimrc, or system-wide in /etc/vimrc.local and then by read from the /etc/vimrc file using:

source /etc/vimrc.local

(you'll have to replace the # comment character with " to make it work in VIM, I wanted to give proper syntax highlighting here).

The commands I've listed here are pretty basic, and the main ones I use so far. They already make me quite more productive, without having to know all the fancy stuff.

The Control + R mechanism is very useful :-) In either insert mode or command mode (i.e. on the : line when typing commands), continue with a numbered or named register:

See :help i_CTRL-R and :help c_CTRL-R for more details, and snoop around nearby for more CTRL-R goodness.

Vim Plugins

There are a lot of good answers here, and one amazing one about the zen of vi. One thing I don't see mentioned is that vim is extremely extensible via plugins. There are scripts and plugins to make it do all kinds of crazy things the original author never considered. Here are a few examples of incredibly handy vim plugins:

rails.vim

Rails.vim is a plugin written by tpope. It's an incredible tool for people doing rails development. It does magical context-sensitive things that allow you to easily jump from a method in a controller to the associated view, over to a model, and down to unit tests for that model. It has saved dozens if not hundreds of hours as a rails developer.

gist.vim

This plugin allows you to select a region of text in visual mode and type a quick command to post it to gist.github.com . This allows for easy pastebin access, which is incredibly handy if you're collaborating with someone over IRC or IM.

space.vim

This plugin provides special functionality to the spacebar. It turns the spacebar into something analogous to the period, but instead of repeating actions it repeats motions. This can be very handy for moving quickly through a file in a way you define on the fly.

surround.vim

This plugin gives you the ability to work with text that is delimited in some fashion. It gives you objects which denote things inside of parens, things inside of quotes, etc. It can come in handy for manipulating delimited text.

supertab.vim

This script brings fancy tab completion functionality to vim. The autocomplete stuff is already there in the core of vim, but this brings it to a quick tab rather than multiple different multikey shortcuts. Very handy, and incredibly fun to use. While it's not VS's intellisense, it's a great step and brings a great deal of the functionality you'd like to expect from a tab completion tool.

syntastic.vim

This tool brings external syntax checking commands into vim. I haven't used it personally, but I've heard great things about it and the concept is hard to beat. Checking syntax without having to do it manually is a great time saver and can help you catch syntactic bugs as you introduce them rather than when you finally stop to test.

fugitive.vim

Direct access to git from inside of vim. Again, I haven't used this plugin, but I can see the utility. Unfortunately I'm in a culture where svn is considered "new", so I won't likely see git at work for quite some time.

nerdtree.vim

A tree browser for vim. I started using this recently, and it's really handy. It lets you put a treeview in a vertical split and open files easily. This is great for a project with a lot of source files you frequently jump between.

FuzzyFinderTextmate.vim

This is an unmaintained plugin, but still incredibly useful. It provides the ability to open files using a "fuzzy" descriptive syntax. It means that in a sparse tree of files you need only type enough characters to disambiguate the files you're interested in from the rest of the cruft.

Conclusion

There are a lot of incredible tools available for vim. I'm sure I've only scratched the surface here, and it's well worth searching for tools applicable to your domain. The combination of traditional vi's powerful toolset, vim's improvements on it, and plugins which extend vim even further, it's one of the most powerful ways to edit text ever conceived. Vim is easily as powerful as emacs, eclipse, visual studio, and textmate.

Thanks

Thanks to duwanis for his vim configs from which I have learned much and borrowed most of the plugins listed here.

Tom Morris, Apr 1, 2010 at 8:50

The magical tests-to-class navigation in rails.vim is one of the more general things I wish Vim had that TextMate absolutely nails across all languages: if I am working on Person.scala and I do Cmd+T, usually the first thing in the list is PersonTest.scala. – Tom Morris Apr 1 '10 at 8:50

Gavin Gilmour, Jan 15, 2011 at 13:44

+1 for Syntastic. That, combined with JSLint, has made my Javascript much less error-prone. See superuser.com/questions/247012/ about how to set up JSLint to work with Syntastic. – Nathan Long Mar 1 '11 at 19:07

AlG, Sep 13, 2011 at 17:37

. Repeat last text-changing command

I save a lot of time with this one.

Visual mode was mentioned previously, but block visual mode has saved me a lot of time when editing fixed size columns in text file. (accessed with Ctrl-V).

vdboor, Apr 1, 2010 at 8:34

Additionally, if you use a concise command (e.g. A for append-at-end) to edit the text, vim can repeat that exact same action for the next line you press the . key at. – vdboor Apr 1 '10 at 8:34

gi

Go to last edited location (very useful if you performed some searching and than want go back to edit)

^P and ^N

Complete previous (^P) or next (^N) text.

^O and ^I

Go to previous ( ^O - "O" for old) location or to the next ( ^I - "I" just near to "O" ). When you perform searches, edit files etc., you can navigate through these "jumps" forward and back.

All in Normal mode:

f<char> to move to the next instance of a particular character on the current line, and ; to repeat.

F<char> to move to the previous instance of a particular character on the current line and ; to repeat.

If used intelligently, the above two can make you killer-quick moving around in a line.

* on a word to search for the next instance.

# on a word to search for the previous instance.

Jim Dennis, Mar 14, 2010 at 6:38

Whoa, I didn't know about the * and # (search forward/back for word under cursor) binding. That's kinda cool. The f/F and t/T and ; commands are quick jumps to characters on the current line. f/F put the cursor on the indicated character while t/T puts it just up "to" the character (the character just before or after it according to the direction chosen. ; simply repeats the most recent f/F/t/T jump (in the same direction). – Jim Dennis Mar 14 '10 at 6:38

Adding and Subtracting

a. Adding and Subtracting

CTRL-A ;Add [count] to the number or alphabetic character at or after the cursor. {not in Vi

CTRL-X ;Subtract [count] from the number or alphabetic character at or after the cursor. {not in Vi}

b. Window key unmapping

In window, Ctrl-A already mapped for whole file selection you need to unmap in rc file. mark mswin.vim CTRL-A mapping part as comment or add your rc file with unmap

c. With Macro

The CTRL-A command is very useful in a macro. Example: Use the following steps to make a numbered list.

  1. Create the first list entry, make sure it starts with a number.
  2. qa - start recording into buffer 'a'
  3. Y - yank the entry
  4. p - put a copy of the entry below the first one
  5. CTRL-A - increment the number
  6. q - stop recording
  7. @a - repeat the yank, put and increment times

Last week at work our project inherited a lot of Python code from another project. Unfortunately the code did not fit into our existing architecture - it was all done with global variables and functions, which would not work in a multi-threaded environment.

We had ~80 files that needed to be reworked to be object oriented - all the functions moved into classes, parameters changed, import statements added, etc. We had a list of about 20 types of fix that needed to be done to each file. I would estimate that doing it by hand one person could do maybe 2-4 per day.

So I did the first one by hand and then wrote a vim script to automate the changes. Most of it was a list of vim commands e.g.

" delete an un-needed function "
g/someFunction(/ d

" add wibble parameter to function foo "
%s/foo(/foo( wibble,/

" convert all function calls bar(thing) into method calls thing.bar() "
g/bar(/ normal nmaf(ldi(`aPa.

The last one deserves a bit of explanation:

g/bar(/  executes the following command on every line that contains "bar("
normal   execute the following text as if it was typed in in normal mode
n        goes to the next match of "bar(" (since the :g command leaves the cursor position at the start of the line)
ma       saves the cursor position in mark a
f(       moves forward to the next opening bracket
l        moves right one character, so the cursor is now inside the brackets
di(      delete all the text inside the brackets
`a       go back to the position saved as mark a (i.e. the first character of "bar")
P        paste the deleted text before the current cursor position
a.       go into insert mode and add a "."

For a couple of more complex transformations such as generating all the import statements I embedded some python into the vim script.

After a few hours of working on it I had a script that will do at least 95% of the conversion. I just open a file in vim then run :source fixit.vim and the file is transformed in a blink of the eye.

We still have the work of changing the remaining 5% that was not worth automating and of testing the results, but by spending a day writing this script I estimate we have saved weeks of work.

Of course it would have been possible to automate this with a scripting language like Python or Ruby, but it would have taken far longer to write and would be less flexible - the last example would have been difficult since regex alone would not be able to handle nested brackets, e.g. to convert bar(foo(xxx)) to foo(xxx).bar() . Vim was perfect for the task.

Dave Kirby, Mar 23, 2010 at 17:16

@lpsquiggle: your suggestion would not handle complex expressions with more than one set of brackets. e.g. if bar(foo(xxx)) or wibble(xxx): becomes if foo(xxx)) or wibble(xxx.bar(): which is completely wrong. – Dave Kirby Mar 23 '10 at 17:16

Use the builtin file explorer! The command is :Explore and it allows you to navigate through your source code very very fast. I have these mapping in my .vimrc :
map <silent> <F8>   :Explore<CR>
map <silent> <S-F8> :sp +Explore<CR>

The explorer allows you to make file modifications, too. I'll post some of my favorite keys, pressing <F1> will give you the full list:

I am a member of the American Cryptogram Association. The bimonthly magazine includes over 100 cryptograms of various sorts. Roughly 15 of these are "cryptarithms" - various types of arithmetic problems with letters substituted for the digits. Two or three of these are sudokus, except with letters instead of numbers. When the grid is completed, the nine distinct letters will spell out a word or words, on some line, diagonal, spiral, etc., somewhere in the grid.

Rather than working with pencil, or typing the problems in by hand, I download the problems from the members area of their website.

When working with these sudokus, I use vi, simply because I'm using facilities that vi has that few other editors have. Mostly in converting the lettered grid into a numbered grid, because I find it easier to solve, and then the completed numbered grid back into the lettered grid to find the solution word or words.

The problem is formatted as nine groups of nine letters, with - s representing the blanks, written in two lines. The first step is to format these into nine lines of nine characters each. There's nothing special about this, just inserting eight linebreaks in the appropriate places.

The result will look like this:

T-O-----C
-E-----S-
--AT--N-L
---NASO--
---E-T---
--SPCL---
E-T--OS--
-A-----P-
S-----C-T

So, first step in converting this into numbers is to make a list of the distinct letters. First, I make a copy of the block. I position the cursor at the top of the block, then type :y}}p . : puts me in command mode, y yanks the next movement command. Since } is a move to the end of the next paragraph, y} yanks the paragraph. } then moves the cursor to the end of the paragraph, and p pastes what we had yanked just after the cursor. So y}}p creates a copy of the next paragraph, and ends up with the cursor between the two copies.

Next, I to turn one of those copies into a list of distinct letters. That command is a bit more complex:

:!}tr -cd A-Z | sed 's/\(.\)/\1\n/g' | sort -u | tr -d '\n'

: again puts me in command mode. ! indicates that the content of the next yank should be piped through a command line. } yanks the next paragraph, and the command line then uses the tr command to strip out everything except for upper-case letters, the sed command to print each letter on a single line, and the sort command to sort those lines, removing duplicates, and then tr strips out the newlines, leaving the nine distinct letters in a single line, replacing the nine lines that had made up the paragraph originally. In this case, the letters are: ACELNOPST .

Next step is to make another copy of the grid. And then to use the letters I've just identified to replace each of those letters with a digit from 1 to 9. That's simple: :!}tr ACELNOPST 0-9 . The result is:

8-5-----1
-2-----7-
--08--4-3
---4075--
---2-8---
--7613---
2-8--57--
-0-----6-
7-----1-8

This can then be solved in the usual way, or entered into any sudoku solver you might prefer. The completed solution can then be converted back into letters with :!}tr 1-9 ACELNOPST .

There is power in vi that is matched by very few others. The biggest problem is that only a very few of the vi tutorial books, websites, help-files, etc., do more than barely touch the surface of what is possible.

I find the following trick increasingly useful ... for cases where you want to join lines that match (or that do NOT match) some pattern to the previous line: :% g/foo/-1j or :'a,'z v/bar/-1j for example (where the former is "all lines and matching the pattern" while the latter is "lines between mark a and mark z which fail to match the pattern"). The part after the patter in a g or v ex command can be any other ex commmands, -1j is just a relative line movement and join command. – Jim Dennis Feb 12 '10 at 4:15

I recently discovered q: . It opens the "command window" and shows your most recent ex-mode (command-mode) commands. You can move as usual within the window, and pressing <CR> executes the command. You can edit, etc. too. Priceless when you're messing around with some complex command or regex and you don't want to retype the whole thing, or if the complex thing you want to do was 3 commands back. It's almost like bash's set -o vi, but for vim itself (heh!).

Visual Mode

As several other people have said, visual mode is the answer to your copy/cut & paste problem. Vim gives you 'v', 'V', and C-v. Lower case 'v' in vim is essentially the same as the shift key in notepad. The nice thing is that you don't have to hold it down. You can use any movement technique to navigate efficiently to the starting (or ending) point of your selection. Then hit 'v', and use efficient movement techniques again to navigate to the other end of your selection. Then 'd' or 'y' allows you to cut or copy that selection.

The advantage vim's visual mode has over Jim Dennis's description of cut/copy/paste in vi is that you don't have to get the location exactly right. Sometimes it's more efficient to use a quick movement to get to the general vicinity of where you want to go and then refine that with other movements than to think up a more complex single movement command that gets you exactly where you want to go.

The downside to using visual mode extensively in this manner is that it can become a crutch that you use all the time which prevents you from learning new vi(m) commands that might allow you to do things more efficiently. However, if you are very proactive about learning new aspects of vi(m), then this probably won't affect you much.

I'll also re-emphasize that the visual line and visual block modes give you variations on this same theme that can be very powerful...especially the visual block mode.

On Efficient Use of the Keyboard

I also disagree with your assertion that alternating hands is the fastest way to use the keyboard. It has an element of truth in it. Speaking very generally, repeated use of the same thing is slow. This most significant example of this principle is that consecutive keystrokes typed with the same finger are very slow. Your assertion probably stems from the natural tendency to use the s/finger/hand/ transformation on this pattern. To some extent it's correct, but at the extremely high end of the efficiency spectrum it's incorrect.

Just ask any pianist. Ask them whether it's faster to play a succession of a few notes alternating hands or using consecutive fingers of a single hand in sequence. The fastest way to type 4 keystrokes is not to alternate hands, but to type them with 4 fingers of the same hand in either ascending or descending order (call this a "run"). This should be self-evident once you've considered this possibility.

The more difficult problem is optimizing for this. It's pretty easy to optimize for absolute distance on the keyboard. Vim does that. It's much harder to optimize at the "run" level, but vi(m) with it's modal editing gives you a better chance at being able to do it than any non-modal approach (ahem, emacs) ever could.

On Emacs

Lest the emacs zealots completely disregard my whole post on account of that last parenthetical comment, I feel I must describe the root of the difference between the emacs and vim religions. I've never spoken up in the editor wars and I probably won't do it again, but I've never heard anyone describe the differences this way, so here it goes. The difference is the following tradeoff:

Vim gives you unmatched raw text editing efficiency Emacs gives you unmatched ability to customize and program the editor

The blind vim zealots will claim that vim has a scripting language. But it's an obscure, ad-hoc language that was designed to serve the editor. Emacs has Lisp! Enough said. If you don't appreciate the significance of those last two sentences or have a desire to learn enough about functional programming and Lisp to develop that appreciation, then you should use vim.

The emacs zealots will claim that emacs has viper mode, and so it is a superset of vim. But viper mode isn't standard. My understanding is that viper mode is not used by the majority of emacs users. Since it's not the default, most emacs users probably don't develop a true appreciation for the benefits of the modal paradigm.

In my opinion these differences are orthogonal. I believe the benefits of vim and emacs as I have stated them are both valid. This means that the ultimate editor doesn't exist yet. It's probably true that emacs would be the easiest platform on which to base the ultimate editor. But modal editing is not entrenched in the emacs mindset. The emacs community could move that way in the future, but that doesn't seem very likely.

So if you want raw editing efficiency, use vim. If you want the ultimate environment for scripting and programming your editor use emacs. If you want some of both with an emphasis on programmability, use emacs with viper mode (or program your own mode). If you want the best of both worlds, you're out of luck for now.

What is the way you use Vim that makes you more productive than with a contemporary editor?

Being able to execute complex, repetitive edits with very few keystrokes (often using macros ). Take a look at VimGolf to witness the power of Vim!

After over ten years of almost daily usage, it's hard to imagine using any other editor.

Use \c anywhere in a search to ignore case (overriding your ignorecase or smartcase settings). E.g. /\cfoo or /foo\c will match foo, Foo, fOO, FOO, etc.

Use \C anywhere in a search to force case matching. E.g. /\Cfoo or /foo\C will only match foo.

Odd nobody's mentioned ctags. Download "exuberant ctags" and put it ahead of the crappy preinstalled version you already have in your search path. Cd to the root of whatever you're working on; for example the Android kernel distribution. Type "ctags -R ." to build an index of source files anywhere beneath that dir in a file named "tags". This contains all tags, nomatter the language nor where in the dir, in one file, so cross-language work is easy.

Then open vim in that folder and read :help ctags for some commands. A few I use often:

Automatic indentation:

You'll need 'filetype plugin indent on' in your .vimrc file, and probably appropriate 'shiftwidth' and 'expandtab' settings.

You asked about productive shortcuts, but I think your real question is: Is vim worth it? The answer to this stackoverflow question is -> "Yes"

You must have noticed two things. Vim is powerful, and vim is hard to learn. Much of it's power lies in it's expandability and endless combination of commands. Don't feel overwhelmed. Go slow. One command, one plugin at a time. Don't overdo it.

All that investment you put into vim will pay back a thousand fold. You're going to be inside a text editor for many, many hours before you die. Vim will be your companion.

:! [command] executes an external command while you're in Vim.

But add a dot after the colon, :.! [command], and it'll dump the output of the command into your current window. That's : . !

For example:

:.! ls

I use this a lot for things like adding the current date into a document I'm typing:

:.! date

saffsd, May 6, 2009 at 14:41

An alternative to :.!date is to write "date" on a line and then run !$sh (alternatively having the command followed by a blank line and run !jsh ). This will pipe the line to the "sh" shell and substitute with the output from the command. – hlovdal Jan 25 '10 at 21:11

de Delete everything till the end of the word by pressing . at your heart's desire.

ci(xyz[Esc] -- This is a weird one. Here, the 'i' does not mean insert mode. Instead it means inside the parenthesis. So this sequence cuts the text inside parenthesis you're standing in and replaces it with "xyz". It also works inside square and figure brackets -- just do ci[ or ci{ correspondingly. Naturally, you can do di (if you just want to delete all text without typing anything. You can also do a instead of i if you want to delete the parentheses as well and not just text inside them.

ci" - cuts the text in current quotes

ciw - cuts the current word. This works just like the previous one except that ( is replaced with w .

C - cut the rest of the line and switch to insert mode.

ZZ -- save and close current file (WAY faster than Ctrl-F4 to close the current tab!)

ddp - move current line one row down

xp -- move current character one position to the right

U - uppercase, so viwU upercases the word

~ - switches case, so viw~ will reverse casing of entire word

Ctrl+u / Ctrl+d scroll the page half-a-screen up or down. This seems to be more useful than the usual full-screen paging as it makes it easier to see how the two screens relate. For those who still want to scroll entire screen at a time there's Ctrl+f for Forward and Ctrl+b for Backward. Ctrl+Y and Ctrl+E scroll down or up one line at a time.

Crazy but very useful command is zz -- it scrolls the screen to make this line appear in the middle. This is excellent for putting the piece of code you're working on in the center of your attention. Sibling commands -- zt and zb -- make this line the top or the bottom one on the sreen which is not quite as useful.

% finds and jumps to the matching parenthesis.

de -- delete from cursor to the end of the word (you can also do dE to delete until the next space)

bde -- delete the current word, from left to right delimiter

df[space] -- delete up until and including the next space

dt. -- delete until next dot

dd -- delete this entire line

ye (or yE) -- yanks text from here to the end of the word

ce - cuts through the end of the word

bye -- copies current word (makes me wonder what "hi" does!)

yy -- copies the current line

cc -- cuts the current line, you can also do S instead. There's also lower cap s which cuts current character and switches to insert mode.

viwy or viwc . Yank or change current word. Hit w multiple times to keep selecting each subsequent word, use b to move backwards

vi{ - select all text in figure brackets. va{ - select all text including {}s

vi(p - highlight everything inside the ()s and replace with the pasted text

b and e move the cursor word-by-word, similarly to how Ctrl+Arrows normally do . The definition of word is a little different though, as several consecutive delmiters are treated as one word. If you start at the middle of a word, pressing b will always get you to the beginning of the current word, and each consecutive b will jump to the beginning of the next word. Similarly, and easy to remember, e gets the cursor to the end of the current, and each subsequent, word.

similar to b / e, capital B and E move the cursor word-by-word using only whitespaces as delimiters.

capital D (take a deep breath) Deletes the rest of the line to the right of the cursor, same as Shift+End/Del in normal editors (notice 2 keypresses -- Shift+D -- instead of 3)

All the things you're calling "cut" is "change". eg: C is change until the end of the line. Vim's equivalent of "cut" is "delete", done with d/D. The main difference between change and delete is that delete leaves you in normal mode but change puts you into a sort of insert mode (though you're still in the change command which is handy as the whole change can be repeated with . ). – Laurence Gonsalves Feb 19 '11 at 23:49

One that I rarely find in most Vim tutorials, but it's INCREDIBLY useful (at least to me), is the

g; and g,

to move (forward, backward) through the changelist.

Let me show how I use it. Sometimes I need to copy and paste a piece of code or string, say a hex color code in a CSS file, so I search, jump (not caring where the match is), copy it and then jump back (g;) to where I was editing the code to finally paste it. No need to create marks. Simpler.

Just my 2cents.

Sometimes a setting in your .vimrc will get overridden by a plugin or autocommand. To debug this a useful trick is to use the :verbose command in conjunction with :set. For example, to figure out where cindent got set/unset:
:verbose set cindent?

This will output something like:

cindent
    Last set from /usr/share/vim/vim71/indent/c.vim

This also works with maps and highlights. (Thanks joeytwiddle for pointing this out.) For example:

:verbose nmap U
n  U             <C-R>
        Last set from ~/.vimrc

:verbose highlight Normal
Normal         xxx guifg=#dddddd guibg=#111111 font=Inconsolata Medium 14
        Last set from ~/src/vim-holodark/colors/holodark.vim

Not sure if this counts as dark-corner-ish at all, but I've only just learnt it...
:g/match/y A

will yank (copy) all lines containing "match" into the "a / @a register. (The capitalization as A makes vim append yankings instead of replacing the previous register contents.) I used it a lot recently when making Internet Explorer stylesheets.

tsukimi, May 27, 2012 at 6:17

Sometimes it's better to do what tsukimi said and just filter out lines that don't match your pattern. An abbreviated version of that command though: :v/PATTERN/d Explanation: :v is an abbreviation for :g!, and the :g command applies any ex command to lines. :y[ank] works and so does :normal, but here the most natural thing to do is just :d[elete] . – pandubear Oct 12 '13 at 8:39

Macros can call other macros, and can also call itself.

eg:

...will delete the first word from every line until the end of the file.

This is quite a simple example but it demonstrates a very powerful feature of vim

Kimball Robinson, Apr 16, 2010 at 0:39

I didn't know macros could repeat themselves. Cool. Note: qx starts recording into register x (he uses qq for register q). 0 moves to the start of the line. dw delets a word. j moves down a line. @q will run the macro again (defining a loop). But you forgot to end the recording with a final "q", then actually run the macro by typing @q. – Kimball Robinson Apr 16 '10 at 0:39

Assuming you have Perl and/or Ruby support compiled in, :rubydo and :perldo will run a Ruby or Perl one-liner on every line in a range (defaults to entire buffer), with $_ bound to the text of the current line (minus the newline). Manipulating $_ will change the text of that line.

You can use this to do certain things that are easy to do in a scripting language but not so obvious using Vim builtins. For example to reverse the order of the words in a line:

:perldo $_ = join ' ', reverse split

To insert a random string of 8 characters (A-Z) at the end of every line:

:rubydo $_ += ' ' + (1..8).collect{('A'..'Z').to_a[rand 26]}.join

You are limited to acting on one line at a time and you can't add newlines.

Sujoy, May 6, 2009 at 18:27

Brian Carper, May 6, 2009 at 18:52

Sadly not, it just adds a funky control character to the end of the line. You could then use a Vim search/replace to change all those control characters to real newlines though. – Brian Carper Jul 2 '09 at 17:26

^O and ^I

Go to older/newer position. When you are moving through the file (by searching, moving commands etc.) vim rember these "jumps", so you can repeat these jumps backward (^O - O for old) and forward (^I - just next to I on keyboard). I find it very useful when writing code and performing a lot of searches.

gi

Go to position where Insert mode was stopped last. I find myself often editing and then searching for something. To return to editing place press gi.

gf

put cursor on file name (e.g. include header file), press gf and the file is opened

gF

similar to gf but recognizes format "[file name]:[line number]". Pressing gF will open [file name] and set cursor to [line number].

^P and ^N

Auto complete text while editing (^P - previous match and ^N next match)

^X^L

While editing completes to the same line (useful for programming). You write code and then you recall that you have the same code somewhere in file. Just press ^X^L and the full line completed

^X^F

Complete file names. You write "/etc/pass" Hmm. You forgot the file name. Just press ^X^F and the filename is completed

^Z or :sh

Move temporary to the shell. If you need a quick bashing:

This is a nice trick to reopen the current file with a different encoding:
:e ++enc=cp1250 %:p

Useful when you have to work with legacy encodings. The supported encodings are listed in a table under encoding-values (see help encoding-values ). Similar thing also works for ++ff, so that you can reopen file with Windows/Unix line ends if you get it wrong for the first time (see help ff ).

Typing == will correct the indentation of the current line based on the line above.

Actually, you can do one = sign followed by any movement command. = {movement}

For example, you can use the % movement which moves between matching braces. Position the cursor on the { in the following code:

if (thisA == that) {
//not indented
if (some == other) {
x = y;
}
}

And press =% to instantly get this:

if (thisA == that) {
    //not indented
    if (some == other) {
        x = y;
    }
}

Alternately, you could do =a{ within the code block, rather than positioning yourself right on the { character.

Let's see some pretty little IDE editor do column transposition.
:%s/\(.*\)^I\(.*\)/\2^I\1/

Explanation

\( and \) is how to remember stuff in regex-land. And \1, \2 etc is how to retrieve the remembered stuff.

>>> \(.*\)^I\(.*\)

Remember everything followed by ^I (tab) followed by everything.

>>> \2^I\1

Replace the above stuff with "2nd stuff you remembered" followed by "1st stuff you remembered" - essentially doing a transpose.

Not exactly a dark secret, but I like to put the following mapping into my .vimrc file, so I can hit "-" (minus) anytime to open the file explorer to show files adjacent to the one I just edit . In the file explorer, I can hit another "-" to move up one directory, providing seamless browsing of a complex directory structures (like the ones used by the MVC frameworks nowadays):
map - :Explore<cr>

These may be also useful for somebody. I like to scroll the screen and advance the cursor at the same time:

map <c-j> j<c-e>
map <c-k> k<c-y>

Tab navigation - I love tabs and I need to move easily between them:

map <c-l> :tabnext<enter>
map <c-h> :tabprevious<enter>

Only on Mac OS X: Safari-like tab navigation:

map <S-D-Right> :tabnext<cr>
map <S-D-Left> :tabprevious<cr>

I often use many windows when I work on a project and sometimes I need to resize them. Here's what I use:
map + <C-W>+
map - <C-W>-

These mappings allow to increase and decrease the size of the current window. It's quite simple but it's fast.

Bill Lynch, Apr 8, 2009 at 2:49

There's also Ctrl-W =, which makes the windows equal width. – Bill Lynch Apr 8 '09 at 2:49

joeytwiddle, Jan 29, 2012 at 18:12

Don't forget you can prepend numbers to perform an action multiple times in Vim. So to expand the current window height by 8 lines: 8<C-W>+ – joeytwiddle Jan 29 '12 at 18:12

:r! <command>

pastes the output of an external command into the buffer.

Do some math and get the result directly in the text:

:r! echo $((3 + 5 + 8))

Get the list of files to compile when writing a Makefile:

:r! ls *.c

Don't look up that fact you read on wikipedia, have it directly pasted into the document you are writing:

Not an obscure feature, but very useful and time saving.

If you want to save a session of your open buffers, tabs, markers and other settings, you can issue the following:

You can open your session using:

I use vim for just about any text editing I do, so I often times use copy and paste. The problem is that vim by default will often times distort imported text via paste. The way to stop this is to use
:set paste

before pasting in your data. This will keep it from messing up.

Note that you will have to issue :set nopaste to recover auto-indentation. Alternative ways of pasting pre-formatted text are the clipboard registers ( * and + ), and :r!cat (you will have to end the pasted fragment with ^D).

It is also sometimes helpful to turn on a high contrast color scheme. This can be done with

:color blue

I've noticed that it does not work on all the versions of vim I use but it does on most.

jamessan, Dec 28, 2009 at 8:27

The "distortion" is happening because you have some form of automatic indentation enabled. Using set paste or specifying a key for the pastetoggle option is a common way to work around this, but the same effect can be achieved with set mouse=a as then Vim knows that the flood of text it sees is a paste triggered by the mouse. – jamessan Dec 28 '09 at 8:27

kyrias, Oct 19, 2013 at 12:15

If you have gvim installed you can often (though it depends on what your options your distro compiles vim with) use the X clipboard directly from vim through the * register. For example "*p to paste from the X xlipboard. (It works from terminal vim, too, it's just that you might need the gvim package if they're separate) – kyrias Oct 19 '13 at 12:15

Here's something not obvious. If you have a lot of custom plugins / extensions in your $HOME and you need to work from su / sudo / ... sometimes, then this might be useful.

In your ~/.bashrc:

export VIMINIT=":so $HOME/.vimrc"

In your ~/.vimrc:

if $HOME=='/root'
        if $USER=='root'
                if isdirectory('/home/your_typical_username')
                        let rtuser = 'your_typical_username'
                elseif isdirectory('/home/your_other_username')
                        let rtuser = 'your_other_username'
                endif
        else
                let rtuser = $USER
        endif
        let &runtimepath = substitute(&runtimepath, $HOME, '/home/'.rtuser, 'g')
endif

It will allow your local plugins to load - whatever way you use to change the user.

You might also like to take the *.swp files out of your current path and into ~/vimtmp (this goes into .vimrc):

if ! isdirectory(expand('~/vimtmp'))
   call mkdir(expand('~/vimtmp'))
endif
if isdirectory(expand('~/vimtmp'))
   set directory=~/vimtmp
else
   set directory=.,/var/tmp,/tmp
endif

Also, some mappings I use to make editing easier - makes ctrl+s work like escape and ctrl+h/l switch the tabs:

inoremap <C-s> <ESC>
vnoremap <C-s> <ESC>
noremap <C-l> gt
noremap <C-h> gT

Ctrl-n while in insert mode will auto complete whatever word you're typing based on all the words that are in open buffers. If there is more than one match it will give you a list of possible words that you can cycle through using ctrl-n and ctrl-p.

Ability to run Vim on a client/server based modes.

For example, suppose you're working on a project with a lot of buffers, tabs and other info saved on a session file called session.vim.

You can open your session and create a server by issuing the following command:

vim --servername SAMPLESERVER -S session.vim

Note that you can open regular text files if you want to create a server and it doesn't have to be necessarily a session.

Now, suppose you're in another terminal and need to open another file. If you open it regularly by issuing:

vim new_file.txt

Your file would be opened in a separate Vim buffer, which is hard to do interactions with the files on your session. In order to open new_file.txt in a new tab on your server use this command:

vim --servername SAMPLESERVER --remote-tab-silent new_file.txt

If there's no server running, this file will be opened just like a regular file.

Since providing those flags every time you want to run them is very tedious, you can create a separate alias for creating client and server.

I placed the followings on my bashrc file:

alias vims='vim --servername SAMPLESERVER'
alias vimc='vim --servername SAMPLESERVER --remote-tab-silent'

You can find more information about this at: http://vimdoc.sourceforge.net/htmldoc/remote.html

HOWTO: Auto-complete Ctags when using Vim in Bash. For anyone else who uses Vim and Ctags, I've written a small auto-completer function for Bash. Add the following into your ~/.bash_completion file (create it if it does not exist):

Thanks go to stylishpants for his many fixes and improvements.

_vim_ctags() {
    local cur prev

    COMPREPLY=()
    cur="${COMP_WORDS[COMP_CWORD]}"
    prev="${COMP_WORDS[COMP_CWORD-1]}"

    case "${prev}" in
        -t)
            # Avoid the complaint message when no tags file exists
            if [ ! -r ./tags ]
            then
                return
            fi

            # Escape slashes to avoid confusing awk
            cur=${cur////\\/}

            COMPREPLY=( $(compgen -W "`awk -vORS=" "  "/^${cur}/ { print \\$1 }" tags`" ) )
            ;;
        *)
            _filedir_xspec
            ;;
    esac
}

# Files matching this pattern are excluded
excludelist='*.@(o|O|so|SO|so.!(conf)|SO.!(CONF)|a|A|rpm|RPM|deb|DEB|gif|GIF|jp?(e)g|JP?(E)G|mp3|MP3|mp?(e)g|MP?(E)G|avi|AVI|asf|ASF|ogg|OGG|class|CLASS)'

complete -F _vim_ctags -f -X "${excludelist}" vi vim gvim rvim view rview rgvim rgview gview

Once you restart your Bash session (or create a new one) you can type:

Code:

~$ vim -t MyC<tab key>

and it will auto-complete the tag the same way it does for files and directories:

Code:

MyClass MyClassFactory
~$ vim -t MyC

I find it really useful when I'm jumping into a quick bug fix.

:setlocal autoread

Auto reloads the current buffer..especially useful while viewing log files and it almost serves the functionality of "tail" program in unix from within vim.

Checking for compile errors from within vim. set the makeprg variable depending on the language let's say for perl

:setlocal makeprg = perl\ -c \ %

For PHP

set makeprg=php\ -l\ %
set errorformat=%m\ in\ %f\ on\ line\ %l

Issuing ":make" runs the associated makeprg and displays the compilation errors/warnings in quickfix window and can easily navigate to the corresponding line numbers.

:make will run the makefile in the current directory, parse the compiler output, you can then use :cn and :cp to step through the compiler errors opening each file and seeking to the line number in question.

:syntax on turns on vim's syntax highlighting.

I was sure someone would have posted this already, but here goes.

Take any build system you please; make, mvn, ant, whatever. In the root of the project directory, create a file of the commands you use all the time, like this:

mvn install
mvn clean install
... and so forth

To do a build, put the cursor on the line and type !!sh. I.e. filter that line; write it to a shell and replace with the results.

The build log replaces the line, ready to scroll, search, whatever.

When you're done viewing the log, type u to undo and you're back to your file of commands.

Due to the latency and lack of colors (I love color schemes :) I don't like programming on remote machines in PuTTY . So I developed this trick to work around this problem. I use it on Windows.

You will need

Setting up remote machine

Configure rsync to make your working directory accessible. I use an SSH tunnel and only allow connections from the tunnel:

address = 127.0.0.1
hosts allow = 127.0.0.1
port = 40000
use chroot = false
[bledge_ce]
    path = /home/xplasil/divine/bledge_ce
    read only = false

Then start rsyncd: rsync --daemon --config=rsyncd.conf

Setting up local machine

Install rsync from Cygwin. Start Pageant and load your private key for the remote machine. If you're using SSH tunelling, start PuTTY to create the tunnel. Create a batch file push.bat in your working directory which will upload changed files to the remote machine using rsync:

rsync --blocking-io *.cc *.h SConstruct rsync://localhost:40001/bledge_ce

SConstruct is a build file for scons. Modify the list of files to suit your needs. Replace localhost with the name of remote machine if you don't use SSH tunelling.

Configuring Vim That is now easy. We will use the quickfix feature (:make and error list), but the compilation will run on the remote machine. So we need to set makeprg:

set makeprg=push\ &&\ plink\ -batch\ xplasil@anna.fi.muni.cz\ \"cd\ /home/xplasil/divine/bledge_ce\ &&\ scons\ -j\ 2\"

This will first start the push.bat task to upload the files and then execute the commands on remote machine using SSH ( Plink from the PuTTY suite). The command first changes directory to the working dir and then starts build (I use scons).

The results of build will show conviniently in your local gVim errors list.

I use Vim for everything. When I'm editing an e-mail message, I use:

gqap (or gwap )

extensively to easily and correctly reformat on a paragraph-by-paragraph basis, even with quote leadin characters. In order to achieve this functionality, I also add:

-c 'set fo=tcrq' -c 'set tw=76'

to the command to invoke the editor externally. One noteworthy addition would be to add ' a ' to the fo (formatoptions) parameter. This will automatically reformat the paragraph as you type and navigate the content, but may interfere or cause problems with errant or odd formatting contained in the message.

Just before copying and pasting to stackoverflow:
:retab 1
:% s/^I/ /g
:% s/^/    /

Now copy and paste code.

As requested in the comments:

retab 1. This sets the tab size to one. But it also goes through the code and adds extra tabs and spaces so that the formatting does not move any of the actual text (ie the text looks the same after ratab).

% s/^I/ /g: Note the ^I is tthe result of hitting tab. This searches for all tabs and replaces them with a single space. Since we just did a retab this should not cause the formatting to change but since putting tabs into a website is hit and miss it is good to remove them.

% s/^/ /: Replace the beginning of the line with four spaces. Since you cant actually replace the beginning of the line with anything it inserts four spaces at the beging of the line (this is needed by SO formatting to make the code stand out).

When working on a project where the build process is slow I always build in the background and pipe the output to a file called errors.err (something like make debug 2>&1 | tee errors.err ). This makes it possible for me to continue editing or reviewing the source code during the build process. When it is ready (using pynotify on GTK to inform me that it is complete) I can look at the result in vim using quickfix . Start by issuing :cf[ile] which reads the error file and jumps to the first error. I personally like to use cwindow to get the build result in a separate window.

Yes, but that's like saying yank/paste functions make an editor "a little" more like an IDE. Those are editor functions. Pretty much everything that goes with the editor that concerns editing text and that particular area is an editor function. IDE functions would be, for example, project/files management, connectivity with compiler&linker, error reporting, building automation tools, debugger ... i.e. the stuff that doesn't actually do nothing with editing text. Vim has some functions & plugins so he can gravitate a little more towards being an IDE, but these are not the ones in question. – Rook May 12 '09 at 21:25

Rook, May 12, 2009 at 21:26

After all, an IDE = editor + compiler + debugger + building tools + ... – Rook May 12 '09 at 21:26

Rook, May 12, 2009 at 21:31

Also, just FYI, vim has an option to set invnumber. That way you don't have to "set nu" and "set nonu", i.e. remember two functions - you can just toggle. – Rook May 12 '09 at 21:31

:ls lists all the currently opened buffers. :be opens a file in a new buffer, :bn goes to the next buffer, :bp to the previous, :b filename opens buffer filename (it auto-completes too). buffers are distinct from tabs, which i'm told are more analogous to views. – Nona Urbiz Dec 20 '10 at 8:25

Use the right mouse key to toggle insert mode in gVim with the following settings in ~/.gvimrc :
"

Neither of the following is really diehard, but I find it extremely useful.

Trivial bindings, but I just can't live without. It enables hjkl-style movement in insert mode (using the ctrl key). In normal mode: ctrl-k/j scrolls half a screen up/down and ctrl-l/h goes to the next/previous buffer. The µ and ù mappings are especially for an AZERTY-keyboard and go to the next/previous make error.

imap <c-j> <Down>
imap <c-k> <Up>
imap <c-h> <Left>
imap <c-l> <Right>
nmap <c-j> <c-d>
nmap <c-k> <c-u>
nmap <c-h> <c-left>
nmap <c-l> <c-right>

nmap ù :cp<RETURN>
nmap µ :cn<RETURN>

A small function I wrote to highlight functions, globals, macro's, structs and typedefs. (Might be slow on very large files). Each type gets different highlighting (see ":help group-name" to get an idea of your current colortheme's settings) Usage: save the file with ww (default "\ww"). You need ctags for this.

nmap <Leader>ww :call SaveCtagsHighlight()<CR>

"Based on: http://stackoverflow.com/questions/736701/class-function-names-highlighting-in-vim
function SaveCtagsHighlight()
    write

    let extension = expand("%:e")
    if extension!="c" && extension!="cpp" && extension!="h" && extension!="hpp"
        return
    endif

    silent !ctags --fields=+KS *
    redraw!

    let list = taglist('.*')
    for item in list
        let kind = item.kind

        if     kind == 'member'
            let kw = 'Identifier'
        elseif kind == 'function'
            let kw = 'Function'
        elseif kind == 'macro'
            let kw = 'Macro'
        elseif kind == 'struct'
            let kw = 'Structure'
        elseif kind == 'typedef'
            let kw = 'Typedef'
        else
            continue
        endif

        let name = item.name
        if name != 'operator=' && name != 'operator ='
            exec 'syntax keyword '.kw.' '.name
        endif
    endfor
    echo expand("%")." written, tags updated"
endfunction

I have the habit of writing lots of code and functions and I don't like to write prototypes for them. So I made some function to generate a list of prototypes within a C-style sourcefile. It comes in two flavors: one that removes the formal parameter's name and one that preserves it. I just refresh the entire list every time I need to update the prototypes. It avoids having out of sync prototypes and function definitions. Also needs ctags.

"Usage: in normal mode, where you want the prototypes to be pasted:
":call GenerateProptotypes()
function GeneratePrototypes()
    execute "silent !ctags --fields=+KS ".expand("%")
    redraw!
    let list = taglist('.*')
    let line = line(".")

            let retType = substitute( retType, '^/\^\s*','','' )
            let retType = substitute( retType, '\s*'.name.'.*', '', '' ) 

            if has_key( item, 'signature' )
                let sig = item.signature
                let sig = substitute( sig, '\s*\w\+\s*,',        ',',   'g')

            else

Create a function to execute the current buffer using it's shebang (assuming one is set) and call it with crtl-x.
map <C-X> :call CallInterpreter()<CR>

map macros

I rather often find it useful to on-the-fly define some key mapping just like one would define a macro. The twist here is, that the mapping is recursive and is executed until it fails.

Example:

enum ProcStats
{
        ps_pid,
        ps_comm,
        ps_state,
        ps_ppid,
        ps_pgrp,
:map X /ps_<CR>3xixy<Esc>X

Gives:

enum ProcStats
{
        xypid,
        xycomm,
        xystate,
        xyppid,
        xypgrp,

Just an silly example :).

I am completely aware of all the downsides - it just so happens that I found it rather useful in some occasions. Also it can be interesting to watch it at work ;).

00dani, Aug 2, 2013 at 11:25

Macros are also allowed to be recursive and work in pretty much the same fashion when they are, so it's not particularly necessary to use a mapping for this. – 00dani Aug 2 '13 at 11:25

There are a lot of threads pertaining to how to configure Vim/GVim for Perl development on PerlMonks.org .

My purpose in posting this question is to try to create, as much as possible, an ideal configuration for Perl development using Vim/GVim. Please post your suggestions for .vimrc settings as well as useful plugins.

I will try to merge the recommendations into a set of .vimrc settings and to a list of recommended plugins, ftplugins and syntax files.

.vimrc settings
"Create a command :Tidy to invoke perltidy"
"By default it operates on the whole file, but you can give it a"
"range or visual range as well if you know what you're doing."
command -range=% -nargs=* Tidy <line1>,<line2>!
    \perltidy -your -preferred -default -options <args>

vmap <tab> >gv    "make tab in v mode indent code"
vmap <s-tab> <gv

nmap <tab> I<tab><esc> "make tab in normal mode indent code"
nmap <s-tab> ^i<bs><esc>

let perl_include_pod   = 1    "include pod.vim syntax file with perl.vim"
let perl_extended_vars = 1    "highlight complex expressions such as @{[$x, $y]}"
let perl_sync_dist     = 250  "use more context for highlighting"

set nocompatible "Use Vim defaults"
set backspace=2  "Allow backspacing over everything in insert mode"

set autoindent   "Always set auto-indenting on"
set expandtab    "Insert spaces instead of tabs in insert mode. Use spaces for indents"
set tabstop=4    "Number of spaces that a <Tab> in the file counts for"
set shiftwidth=4 "Number of spaces to use for each step of (auto)indent"

set showmatch    "When a bracket is inserted, briefly jump to the matching one"
syntax plugins ftplugins CPAN modules Debugging tools

I just found out about VimDebug . I have not yet been able to install it on Windows, but looks promising from the description.

The .vimrc settings should be heavily commented. E.g., what does perl_include_pod do? – innaM Oct 15 '09 at 19:06

@Manni: You are welcome. I have been using the same .vimrc for many years and a recent bunch of vim related questions got me curious. I was too lazy to wade through everything that was posted on PerlMonks (and see what was current etc.), so I figured we could put together something here. – Sinan άnόr Oct 15 '09 at 20:02

Telemachus, Jul 8, 2010 at 0:40

Rather than closepairs, I would recommend delimitMate or one of the various autoclose plugins. (There are about three named autoclose, I think.) The closepairs plugin can't handle a single apostrophe inside a string (i.e. print "This isn't so hard, is it?" ), but delimitMate and others can. github.com/Raimondi/delimitMate – Telemachus Jul 8 '10 at 0:40

From chromatic's blog (slightly adapted to be able to use the same mapping from all modes).
vmap, pt :!perltidy<CR> 
nmap, pt :%! perltidy<CR>

hit, pt in normal mode to clean up the whole file, or in visual mode to clean up the selection. You could also add:

imap, pt <ESC>:%! perltidy<CR>

But using commands from input mode is not recommended.

innaM, Oct 21, 2009 at 9:21

I seem to be missing something here: How can I type, ptv without vim running perltidy on the entire file? – innaM Oct 21 '09 at 9:21

Ovid's comment (#3) seems offer a much better solution. – innaM Oct 21 '09 at 9:23

innaM, Oct 21, 2009 at 13:22

Three hours later: turns out that the 'p' in that mapping is a really bad idea. It will bite you when vim's got something to paste. – innaM Oct 21 '09 at 13:22

Ether, Oct 21, 2009 at 15:23

@Manni: select a region first: with the mouse if using gvim, or with visual mode ( v and then use motion commands). – Ether Oct 21 '09 at 15:23

Ether, Oct 21, 2009 at 19:44

@Manni: I just gave it a try: if you type, pt, vim waits for you to type something else (e.g. <cr>) as a signal that the command is ended. Hitting, ptv will immediately format the region. So I would expect that vim recognizes that there is overlap between the mappings, and waits for disambiguation before proceeding. – Ether Oct 21 '09 at 19:44

I have 2.

The first one I know I picked up part of it from someone else, but I can't remember who. Sorry unknown person. Here's how I made "C^N" auto complete work with Perl. Here's my .vimrc commands.

" to use CTRL+N with modules for autocomplete "
set iskeyword+=:
set complete+=k~/.vim_extras/installed_modules.dat

Then I set up a cron to create the installed_modules.dat file. Mine is for my mandriva system. Adjust accordingly.

locate *.pm | grep "perl5" | sed -e "s/\/usr\/lib\/perl5\///" | sed -e "s/5.8.8\///" | sed -e "s/5.8.7\///" | sed -e "s/vendor_perl\///" | sed -e "s/site_perl\///" | sed -e "s/x86_64-linux\///" | sed -e "s/\//::/g" | sed -e "s/\.pm//" >/home/jeremy/.vim_extras/installed_modules.dat

The second one allows me to use gf in Perl. Gf is a shortcut to other files. just place your cursor over the file and type gf and it will open that file.

" To use gf with perl "
set path+=$PWD/**,
set path +=/usr/lib/perl5/*,
set path+=/CompanyCode/*,   " directory containing work code "
autocmd BufRead *.p? set include=^use
autocmd BufRead *.pl set includeexpr=substitute(v:fname,'\\(.*\\)','\\1.pm','i')

By far the most useful are
  1. Perl filetype pluging (ftplugin) - this colour-codes various code elements
  2. Creating a check-syntax-before-saving command "W" preventing you from saving bad code (you can override with the normal 'w').

Installing he plugins are a bit dicky as the version of vim (and linux) put the plugins in different places. Mine are in ~/.vim/after/

my .vimrc below.

set ts=2
set sw=2
set enc=utf-8
set fileencoding=utf-8

[Oct 21, 2018] What is vim recording and how can it be disabled?

Oct 21, 2018 | stackoverflow.com

vehomzzz, Oct 6, 2009 at 20:03

I keep seeing the recording message at the bottom of my gvim 7.2 window.

What is it and how do I turn it off?

Joey Adams, Aug 17, 2010 at 16:26

To turn off vim recording for good, add map q <Nop> to your .vimrc file. – Joey Adams Aug 17 '10 at 16:26

0xc0de, Aug 12, 2016 at 9:04

I can't believe you want to turn recording off! I would show a really annoying popup 'Are you sure?' if one asks to turn it off (or probably would like to give options like the Windows 10 update gives). – 0xc0de Aug 12 '16 at 9:04

yogsototh, Oct 6, 2009 at 20:08

You start recording by q<letter> and you can end it by typing q again.

Recording is a really useful feature of Vim.

It records everything you type. You can then replay it simply by typing @<letter> . Record search, movement, replacement...

One of the best feature of Vim IMHO.

Cascabel, Oct 6, 2009 at 20:13

As seen other places, it's q followed by a register. A really cool (and possibly non-intuitive) part of this is that these are the same registers used by things like delete, yank, and put. This means that you can yank text from the editor into a register, then execute it as a command. – Cascabel Oct 6 '09 at 20:13

Tolga E, Aug 17, 2013 at 3:07

One more thing to note is you can hit any number before the @ to replay the recording that many times like (100@<letter>) will play your actions 100 times – Tolga E Aug 17 '13 at 3:07

anisoptera, Dec 4, 2014 at 9:43

You could add it afterward, by editing the register with put/yank. But I don't know why you'd want to turn recording on or off as part of a macro. ('q' doesn't affect anything when typed in insert mode.) – anisoptera Dec 4 '14 at 9:43

It sounds like you have macro recording turned on. To shut it off, press q .

Refer to " :help recording " for further information.

mitchus, Feb 13, 2015 at 14:16

Typing q starts macro recording, and the recording stops when the user hits q again.

As Joey Adams mentioned, to disable recording, add the following line to .vimrc in your home directory:

map q <Nop>

n611x007, Oct 4, 2015 at 7:16

only answer about "how to turn off" part of the question. Well, it makes recording inaccessible, effectively turning it off - at least noone expects vi to have a separate thread for this code, I guess, including me. – n611x007 Oct 4 '15 at 7:16

JeffH, Oct 6, 2009 at 20:10

As others have said, it's macro recording, and you turn it off with q. Here's a nice article about how-to and why it's useful.

John Millikin, Oct 6, 2009 at 20:06

It means you're in "record macro" mode. This mode is entered by typing q followed by a register name, and can be exited by typing q again.

ephemient, Oct 6, 2009 at 20:08

It's actually entered by typing q followed by any register name, which is 0-9, a-z, A-Z, and ". – ephemient Oct 6 '09 at 20:08

Cascabel, Oct 6, 2009 at 20:08

Actually, it's q{0-9a-zA-Z"} - you can record a macro into any register (named by digit, letter, "). In case you actually want to use it... you execute the contents of a register with @<register>. See :help q and :help @ if you're interested in using it. – Cascabel Oct 6 '09 at 20:08

[Oct 20, 2018] Do commands (bufdo, windo, tabdo, argdo)

Oct 20, 2018 | my.safaribooksonline.com

Vim provides an incredibly powerful (and flexible) set of commands, which allow a set of arbitrary commands to be executed against an entire list. In Vim parlance a "list" could be one of the following: a group of open buffers, tabs, windows, and even Vim's argument list (which I'll explain near the end of this chapter).

For each list type (buffer list, tab list, window list, argument list) Vim provides a command which enables us to carry out actions in bulk (i.e., across multiple items). Let's take a look at each of these commands in turn.

bufdo

As we already know, when you open a file in Vim, you're, in fact, actually opening a buffer that holds a copy of the file you requested. (If you're unsure, I suggest going back and reading Chapter 3 ).

Every buffer we create in Vim is added into an internal buffer list. This internal list is what allows Vim to keep track of the current buffer and facilitates commands such as bn and bp , among others, for navigating back and forth among all open buffers.

If we wanted to execute the same command for each buffer that exists in our buffer list, we would have to use the :bufdo command

. The flow of how this looks internally is something like the following:

At this point, if an error occurs, Vim will stop processing the buffers and return the error. If, on the other hand, Vim manages to process all the buffers, the last one becomes the current buffer within the viewport.

Simple Example

Now that we have an understanding of what a buffer list is, we can look at how the bufdo command works. Let's consider a simple example, in which we have a set of buffers already open within Vim and we've made changes to each of the buffers already.

We want to exit Vim, but as we do, we have to make sure that each buffer is written back to the relevant file it corresponds to, so we don't lose any of our changes. The following command demonstrates how to do this:

:bufdo wq

Effectively, we've told Vim to process each buffer (using the bufdo command), and within each buffer, we want Vim to execute the command wq (meaning we want it to first write the buffer, then close the buffer).

Image Note In the preceding example, you can also achieve the same result with :wa ( :h :wa ), which effectively allows you to write only the buffers that have been changed in some way.

[Oct 19, 2018] Visual Mode

Notable quotes:
"... Vim's Operator Commands ..."
Oct 19, 2018 | my.safaribooksonline.com

Vim's Visual mode allows us to define a selection of text and then operate upon it. This should feel pretty intuitive, since it is the model that most editing software follows. But Vim's take is characteristically different, so we'll start by making sure we grok Visual mode ( Tip 20 ).

Vim has three variants of Visual mode involving working with characters, lines, or rectangular blocks of text. We'll explore ways of switching between these modes as well as some useful tricks for modifying the bounds of a selection ( Tip 21 ).

We'll see that the dot command can be used to repeat Visual mode commands, but that it's especially effective when operating on line-wise regions. When working with character-wise selections, the dot command can sometimes fall short of our expectations. We'll see that in these scenarios, operator commands may be preferable.

Visual-Block mode is rather special in that it allows us to operate on rectangular columns of text. You'll find many uses for this feature, but we'll focus on three tips that demonstrate some of its capabilities.

Visual mode allows us to select a range of text and then operate upon it. However intuitive this might seem, Vim's perspective on selecting text is different from other text editors.

Suppose for a minute that we're not working with Vim but instead filling out a text area on a web page. We've written the word "March," but it should read "April," so using the mouse, we double-click the word to select it. Having highlighted the word, we could hit the backspace key to delete it and then type out the correct month as a replacement.

You probably already know that there's no need to hit the backspace key in this example. With the word "March" selected, we would only have to type the letter "A" and it would replace the selection, preparing the way so that we could type out the rest of the word "April." It's not much, but a keystroke saved is a keystroke earned.

If you expect this behavior to carry over to Vim's Visual mode, you're in for a surprise. The clue is right there in the name: Visual mode is just another mode, which means that each key performs a different function.

Many of the commands that you are familiar with from Normal mode work just the same in Visual mode. We can still use h , j , k , and l as cursor keys. We can use f{char} to jump to a character on the current line and then repeat or reverse the jump with the ; and , commands, respectively. We can even use the search command (and n / N ) to jump to pattern matches. Each time we move our cursor in Visual mode, we change the bounds of the selection.

Some Visual mode commands perform the same basic function as in Normal mode but with a slight twist. For example, the c command is consistent in both modes in that it deletes the specified text and then switches to Insert mode. The difference is in how we specify the range on which to act. From Normal mode, we trigger the change command first and then specify the range as a motion. This, if you'll remember from Tip 12 , is called an operator command. Whereas in Visual mode, we start off by making the selection and then trigger the change command. This inversion of control can be generalized for all operator commands (see Table 2, ​ Vim's Operator Commands ). For most people, the Visual mode approach feels more intuitive.

Let's revisit the simple example where we wanted to change the word "March" to "April." This time, suppose that we have left the confines of the text area on a web page and we're comfortably back inside Vim. We place our cursor somewhere on the word "March" and run viw to visually select the word. Now, we can't just type the word "April" because that would trigger the A command and append the text "pril"! Instead, we'll use the c command to change the selection, deleting the word and dropping us into Insert mode, where we can type out the word "April" in full. This pattern of usage is similar to our original example, except that we use the c key instead of backspace.

Meet Select Mode

In a typical text editing environment, selected text is deleted when we type any printable character. Vim's Visual mode doesn't follow this convention -- but Select mode does. According to Vim's built-in documentation, it "resembles the selection mode in Microsoft Windows" (see Select-mode ). Printable characters cause the selection to be deleted, Vim enters Insert mode, and the typed character is inserted.

We can toggle between Visual and Select modes by pressing <C-g> . The only visible difference is the message at the bottom of screen, which switches between -- VISUAL -- and -- SELECT -- . But if we type any printable character in Select mode, it will replace the selection and switch to Insert mode. Of course, from Visual mode you could just as well use the c key to change the selection.

If you are happy to embrace the modal nature of Vim, then you should find little use for Select mode, which holds the hand of users who want to make Vim behave more like other text editors. I can think of only one place where I consistently use Select mode: when using a plugin that emulates TextMate's snippet functionality, Select mode highlights the active placeholder.

[Oct 19, 2018] Vim faster way to select blocks of text in visual mode - Stack Overflow

Vim: faster way to select blocks of text in visual mode Ask Question up vote 149 down vote favorite 65


Calvin Cheng ,Sep 13, 2011 at 18:52

I have been using vim for quite some time and am aware that selecting blocks of text in visual mode is as simple as SHIFT + V and moving the arrow key up or down line-by-line until I reach the end of the block of text that I want selected.

My question is - is there a faster way in visual mode to select a block of text for example by SHIFT + V followed by specifying the line number in which I want the selection to stop? (via :35 for example, where 35 is the line number I want to select up to - this obviously does not work so my question is to find how if something similar to this can be done...)

user786653 ,Sep 13, 2011 at 19:08

for line selecting I use shortcut: nnoremap <Space> V . When in visual line mode just right-click with mouse to define selection (at least on linux it is so). Anyway, more effective than with keyboard only. – Mikhail V Mar 27 '15 at 16:52

Jay ,Sep 13, 2011 at 19:05

In addition to what others have said, you can also expand your selection using pattern searches.

For example, v/foo will select from your current position to the next instance of "foo." If you actually wanted to expand to the next instance of "foo," on line 35, for example, just press n to expand selection to the next instance, and so on.

update

I don't often do it, but I know that some people use marks extensively to make visual selections. For example, if I'm on line 5 and I want to select to line 35, I might press ma to place mark a on line 5, then :35 to move to line 35. Shift + v to enter linewise visual mode, and finally `a to select back to mark a .

@DanielPark To select the current word, use v i w . If you want to select the current contiguous non-whitespace, use v i Shift + w .

Vim is a language. To really understand Vim, you have to know the language. Many commands are verbs, and vim also has objects and prepositions.
V100G
V100gg

This means "select the current line up to and including line 100."

Text objects are where a lot of the power is at. They introduce more objects with prepositions.

Vap

This means "select around the current paragraph", that is select the current paragraph and the blank line following it.

V2ap

This means "select around the current paragraph and the next paragraph."

}V-2ap

This means "go to the end of the current paragraph and then visually select it and the preceding paragraph."

Understanding Vim as a language will help you to get the best mileage out of it.

After you have selecting down, then you can combine with other commands:

Vapd

With the above command, you can select around a paragraph and delete it. Change the d to a y to copy or to a c to change or to a p to paste over.

Once you get the hang of how all these commands work together, then you will eventually not need to visually select anything. Instead of visually selecting and then deleting a paragraph, you can just delete the paragraph with the dap command.

v puts you in select mode, 35 specifies the line number that you want to G go to.

You could also use v} which will select everything up to the beginning of the next paragraph.

[Oct 19, 2018] Accessing Multiple Files in VIM

Oct 19, 2018 | stackoverflow.com

Léo Léopold Hertz, Apr 19, 2009 at 2:44

The book "Unix in a Nutshell" discusses about accessing multiple files on pages 572-573. There seem to be very useful commands such as ":e", ":e #", ":e new_file", ":n files", ":args", ":prev" and ":n!". The commands confuse me:

":n Edit next file in the list of files."

":args Display list of files to be edited."

":prev Edit previous file in the list of files."

I cannot see no real list when I do ":args". There is only a small text at the corner. I would like to see all files that I accessed with ":e", ie a list of files in the buffer.

Where can I see the list when I do the command ":n files"? What are the commands ":prev" and ":n" supposed to do? I got the error message:

There is only one file to edit.

Rook, Apr 19, 2009 at 3:25

Regarding the last part: If you have only one buffer open, then you cannot toggle through them ('cause there is only one open). – Rook Apr 19 '09 at 3:25

Rook, Apr 19, 2009 at 3:20

I've not read the book in mention, but I'll try to explain how vim handles files.

Vim has buffers. You open every file with:

:e name_of_the_file.txt (loads file in a buffer, i.e. "opens file")

You can also:

:e *.txt

Useful options while doing this are

:set laststatus=2 (to always show the statusline)

:set wildmenu (to ease opening files)

If you have standard vim with netrw plugin, you can:

:e . (for one of vim's file managers, so to say)

To manage buffers:

:ls will give you a list of currently opened buffers (files)

:bnext , and :bprevious (or :bn and :bp ) enable you to cycle through buffers

:bd closes the buffer/file (buffer done)

Other buffer types serve other purposes (yanking/pasting, temporary, vim's internal, ... etc.)

Léo Léopold Hertz 준영 ,Apr 19, 2009 at 3:57

Is the notation of buffer the same as in Emacs? Interestingly, the book defines buffer only for Emacs :( It states "When you open a file in Emacs, the file is put into a Buffer. -- The view of the buffer contents that you have at any point in time is called a window." Are the buffers and windows different to the things in Vim? – Léo Léopold Hertz 준영 Apr 19 '09 at 3:57

Rook ,Apr 19, 2009 at 11:08

Yes, you could say that. There are some differences in types of available buffers, but in principle, that's it. I'm not sure about emacs, he has windows/frames .., while vim has windows/tabs. Regarding vim: a window is only y method of showing what vim has in a buffer. A tab is a method of showing several windows on screen (tabs in vim have only recently been introduced). – Rook Apr 19 '09 at 11:08

Kyle Strand ,Sep 28, 2015 at 17:24

I don't think :e *.txt can be used to open multiple files. :next appears to work, though: stackoverflow.com/a/12304605/1858225Kyle Strand Sep 28 '15 at 17:24

Brian Carper ,Apr 19, 2009 at 4:05

In addition to what Jonathan Leffler said, if you don't invoke Vim with multiple files from the commandline, you can set Vim's argument list after Vim is open via:
:args *.c

Note that the argument list is different from the list of open buffers you get from :ls . Even if you close all open buffers in Vim, the argument list stays the same. :n and :prev may open a brand new buffer in Vim (if a buffer for that file isn't already open), or may take you to an existing buffer.

Similarly you can open multiple buffers in Vim without affecting the argument list (or even if the arg list is empty). :e opens a new buffer but doesn't necessarily affect the argument list. The list of open buffers and the argument list are independent. If you want to iterate through the list of open buffers rather than iterate through the argument list, use :bn and :bp and friends.

Jonathan Leffler ,Apr 19, 2009 at 2:54

For those commands to make sense, you do:
vim *.c

in a directory where there are twenty C files, for example. With a single file, there is no next or previous or significant list of files.

Léo Léopold Hertz 준영 ,Apr 19, 2009 at 3:48

Wow! Very nice example :) Great thanks! – Léo Léopold Hertz 준영 Apr 19 '09 at 3:48

DanM ,Apr 19, 2009 at 4:02

The :n :p :ar :rew :last operate on the command line argument list.

E.g.

> touch aaa.txt bbb.txt ccc.txt
> gvim *.txt

vim opens in aaa.txt

:ar gives a status line

[aaa.txt] bbb.txt ccc.txt

:n moves to bbb.txt

:ar gives the status line

aaa.txt [bbb.txt] ccc.txt

:rew rewinds us back to the start of the command line arg list to aaa.txt

:last sends us to ccc.txt

:e ddd.txt edits a new file ddd.txt

:ar gives the status line

aaa.txt bbb.txt [ccc.txt]

So the command set only operates on the initial command line argument list.

,

To clarify, Vim has the argument list, the buffer list, windows, and tab pages. The argument list is the list of files you invoked vim with (e.g. vim file1 file2); the :n and :p commands work with this. The buffer list is the list of in-memory copies of the files you are editing, just like emacs. Note that all the files loaded at start (in the argument list) are also in the buffer list. Try :help buffer-list for more information on both.

Windows are viewports for buffers. Think of windows as "desks" on which you can put buffers to work on them. Windows can be empty or be displaying buffers that can also be displayed in other windows, which you can use for example to look at two different areas of the same buffer at the same time. Try :help windows for more info.

Tabs are collections of windows. For example, you can have one tab with one window, and another tab with two windows vertically split. Try :help tabpage for more info

Run a command in multiple buffers Edit

Tip 133 Printable Monobook Previous Next

created 2001 · complexity basic · version 6.0


This tip shows how to apply a command multiple times using :argdo (all files in argument list), or :bufdo (all buffers), or :tabdo (all tabs), or :windo (all windows in the current tab). See search and replace in multiple buffers for the common requirement to perform a substitute multiple times.

Bufdo Edit

You may want to perform the same operation on each buffer. For example, you may have recorded a macro to register a and want to apply the macro to each buffer. You could do that by entering:

:bufdo execute "normal! @a" | w

The w will write each buffer to disk (whether the buffer was changed or not). To only write if changed, use:

:bufdo execute "normal! @a" | update

An alternative is to set the 'autowrite' option so changed buffers are automatically saved when switching to another buffer:

:set autowrite
:bufdo normal! @a

Yet another alternative is to set the 'hidden' option so buffers do not need to be saved, then use :wa to save all changes (only changed buffers are written):

:set hidden
:bufdo normal! @a
:wa

TO DO

Refactor following.

The command to do normal commands from the command-line is "normal" and I wanted to run the macro recorded in register a , so that explains the "normal @a".

I also wanted to do this over multiple buffers, which explains the "bufdo".

However, I also wanted to make the changes and then save the file so it moved happily onto the next buffer and everything was saved. This required the use of the | w. Initially I tried:

:bufdo normal @a | w

but that didn't work as the "| w" part was interpreted as a normal command, so that's where the exe command comes from.

Restoring position Edit

The commands bufdo, windo and tabdo are great for operating on all buffers or windows or tabs. However, the commands finish in a different place from where you started.

These versions (Bufdo, Windo and Tabdo) restore the current window or buffer or tab, when the command is finished.

For example, to turn on line numbers everywhere, I use :Windo set nu . Using :windo set nu does the same, but the cursor finishes in a different window.

" Like windo but restore the current window.
function! WinDo(command)
  let currwin=winnr()
  execute 'windo ' . a:command
  execute currwin . 'wincmd w'
endfunction
com! -nargs=+ -complete=command Windo call WinDo(<q-args>)
" Like bufdo but restore the current buffer.
function! BufDo(command)
  let currBuff=bufnr("%")
  execute 'bufdo ' . a:command
  execute 'buffer ' . currBuff
endfunction
com! -nargs=+ -complete=command Bufdo call BufDo(<q-args>)
" Like tabdo but restore the current tab.
function! TabDo(command)
  let currTab=tabpagenr()
  execute 'tabdo ' . a:command
  execute 'tabn ' . currTab
endfunction
com! -nargs=+ -complete=command Tabdo call TabDo(<q-args>)

If you care about the alternate window or buffer as well, you can save these along with the current window or buffer:

" Like windo but restore the current window.
function! WinDo(command)
  let currwin=winnr()
  let curaltwin=winnr('#')
  execute 'windo ' . a:command
  " restore previous/alt window
  execute curaltwin . 'wincmd w'
  " restore current window
  execute currwin . 'wincmd w'
endfunction
com! -nargs=+ -complete=command Windo call WinDo(<q-args>)
References Edit Comments Edit Todo Edit

Tips 1160 and 1161 have some interesting code (although I would never use it). Tip 1160 mentions 'autowrite', and can be used as a 'see also' here. Although perhaps my new examples are sufficient?

Tip 1161 has a WinDo command. Perhaps move anything useful from there to here (or perhaps move all the "Xdo and restore" from here to there?).

Need to explain argdo somewhere, and need a little more on windo and tabdo. Should start this tip with something that does not use 'normal' (which requires the tricky execute when using bar).

If you're like me and don't keep your buffer list very tidy, or just work on multiple things at once in a single Vim, bufdo is rarely useful. If you want to act on a bunch of files, too many to readily open a new tab with a window for each of them, then windo is not very useful either. argdo shines for quickly doing a command on a large batch of files when you're already using Vim with a bunch of buffers unrelated to the task. For example, I recently had to:
cd /doc/directory/of/unnamed/tool
args *.html
argdo 0put ='<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\" \"http://www.w3.org/TR/html1/DTD/html-trad.dtd\">' | w
A tool which will remain unnamed because they ought to know better, distributed their tool with HTML documentation which is broken partially due to the lack of a doctype causing IE8 to parse it in "quirks mode" (even though they specifically targeted this browser version for the tool itself). So, I used the above command to very quickly correct the problem on every html file in their documentation directory in my install location.
Truth be told, in reality I did not use argdo, I instead recorded a macro to do ggP:wnext<CR> and just pressed @@ on each file (because I wanted to check for a doctype on each before adding one). But, were I confident I needed to do this on ALL the files, I would have used argdo as above.
-- Fritzophrenic 15:16, August 12, 2011 (UTC)

Here is something tricky I needed recently:

:bufdo call search('pattern')

I wanted to put the cursor on the next occurrence of pattern in each buffer, but I found that :bufdo normal! n or other search attempts did not work. I thought I had searched before, but I could not make it work without the trick above. Any insight? JohnBeckett 08:15, August 12, 2011 (UTC)

No idea, I would expect this to work. Maybe you've got some autocmd in your .vimrc to restore a search or something when loading a buffer? I note that search history is in the .viminfo file, but that should only be loaded on startup.
It seems to work for me, though for some reason the current buffer jumps the cursor to the line containing the match, but not to the match itself. Probably that's something in my config.
-- Fritzophrenic 15:16, August 12, 2011 (UTC)
Very strange, I just tried it again and there was no problem. Must have been a blunder or some temporary config glitch. Thanks. I'm getting converted to argdo, and I'm planning a rewrite featuring argdo, and mentioning the others. JohnBeckett 10:37, August 13, 2011 (UTC)
Yeah, I almost never used the arglist until I discovered :args and :argl . Now I use it almost exclusively when doing batch edits. Although, I normally use :next and :wnext rather than :argdo . Fritzophrenic 15:33, August 15, 2011 (UTC)
Tip titles Edit

These tips should handle the basics for argdo/bufdo/tabdo/windo (redirects bufdo , tabdo , windo point to this tip, and I would also make argdo ):

Should we rename these, perhaps:

The "files" is not strictly correct since it might be just a buffer with no file. However, for simplicity (and Google searching), using "files" for the title seems best? JohnBeckett 10:37, August 13, 2011 (UTC)

I'm all for simplicity. But what about making the actual tip say "buffers" and make a redirect with "files"? I'm not sure how well Google handles that but obviously the wikia search handles it well. That way we can satisfy both the pedantic and those searching for an answer. -- Fritzophrenic 15:33, August 15, 2011 (UTC)
OK. Tips will be "buffers", and redirects "files". Will do, and will remove these comments. JohnBeckett 03:52, August 16, 2011 (UTC)

Vim provides various commands and options to support editing multiple buffers. This document covers some of the questions asked about using multiple buffers with Vim. You can get more detailed information about Vim buffer support using the :help windows.txt command in Vim. You can also use the help keywords mentioned in this document to read more about a particular command or option. To read more about a particular command or option use the ":help <helpkeyword>" command (replace helpkeyword with the command or option name).

See easier buffer switching if all you want is information on switching between buffers.

What is a Vim buffer?

A buffer is a file loaded into memory for editing. All opened files are associated with a buffer. There are also buffers not associated with any file.

:help windows-intro

How do I identify a buffer?

Vim buffers are identified using a name and a number. The name of the buffer is the name of the file associated with that buffer. The buffer number is a unique sequential number assigned by Vim. This buffer number will not change in a single Vim session.

:help buffers

How do I create a buffer?

When you open a file using any of the Vim commands, a buffer is automatically created. For example, if you use :edit file to edit a file, a new buffer is automatically created. An empty buffer can be created by entering :new or :vnew .

How do I add a new buffer for a file to the buffer list without opening the file?

You can add a new buffer for a file without opening it, using the ":badd" command. For example,

:badd f1.txt
:badd f2.txt

The above commands will add two new buffers for the files f1.txt and f2.txt to the buffer list.

:help :badd

How do I get a list of all the existing buffers?

You can get a list of all the existing buffers using the ":buffers" or ":ls" or ":files" command. This list is called the 'buffer list'.

To display all the buffers including unlisted buffers, use the ":buffers!" or ":ls!" or ":files!" command.

How do I delete a buffer?

You can delete a buffer using the ":bdelete" command. You can use either the buffer name or the buffer number to specify a buffer. For example,

:bdelete f1.txt
:bdelete 4

The above commands will delete the buffer named "f1.txt" and the fourth buffer in the buffer list. The ":bdelete" command will remove the buffer from the buffer list.

When a buffer is deleted, the buffer becomes an unlisted-buffer and is no longer included in the buffer list. But the buffer name and other information associated with the buffer is still remembered. To completely delete the buffer, use the ":bwipeout" command. This command will remove the buffer completely (i.e. the buffer will not become a unlisted buffer).

How do I delete multiple buffers?

You can delete multiple buffers in several ways:

:3,5bdelete
:bdelete buf1.txt buf2.c buf3.h

In this example, after typing ":bdelete buf", you can press <Ctrl-A> to expand all the buffer names starting with 'buf'.

How do I remove a buffer from a window?

You can remove a buffer displayed in a window in several ways:

  1. Close the window or edit another buffer/file in that window.
  2. Use the ":bunload" command. This command will remove the buffer from the window and unload the buffer contents from memory. The buffer will not be removed from the buffer list.

:help :bunload

How do I edit an existing buffer from the buffer list?

You can edit or jump to a buffer in the buffer list in several ways:

  1. Use the ":buffer" command passing the name of an existing buffer or the buffer number. Note that buffer name completion can be used here by pressing the <Tab> key.
  2. You can enter the buffer number you want to jump/edit and press the Ctrl-^ key.
  3. Use the ":sbuffer" command passing the name of the buffer or the buffer number. Vim will split open a new window and open the specified buffer in that window.
  4. You can enter the buffer number you want to jump/edit and press the Ctrl-W ^ or Ctrl-W Ctrl-^ keys. This will open the specified buffer in a new window.

How do I browse through all the available buffers?

You can browse through the buffers in the buffer list in several ways:

  1. To jump to the first buffer in the buffer list, use the ":bfirst" or ":brewind" command.
  2. To jump to the first buffer in the buffer list in a new window, use the ":sbfirst" or ":sbrewind" command.
  3. To edit the next buffer in the buffer list, use the ":bnext" command., or the abbreviated ":bn"
  4. To open the next buffer in the buffer list in a new window, use the ":sbnext" command.
  5. To edit the previous buffer in the buffer list, use the ":bprevious" or ":bNext" command. or the abbreviated ":bp"
  6. To open the previous buffer in the buffer list in a new window, use the ":sbprevious" or ":sbNext" command.
  7. To open the last buffer in the buffer list, use the ":blast" command.
  8. To open the last buffer in the buffer list in a new window, use the ":sblast" command.

How do I open all the buffers in the buffer list?

You can open all the buffers present in the buffer list using the ":ball" or ":sball" commands.

How do I open all the loaded buffers?

You can open all the loaded buffers in the buffer list using the ":unhide" or ":sunhide" commands. Each buffer will be loaded in a separate new window.

How do I open the next modified buffer?

You can open the next or a specific modified buffer using the ":bmodified" command. You can open the next or a specific modified buffer in a new window using the ":sbmodified" command.

Is there a simpler way for using the buffers under gvim (GUI Vim)?

Yes, use the 'Buffers' menu to list all the buffers. You can select a buffer name to edit the buffer. You can also delete a buffer or browse the buffer list. Click the dashed line at the top of the menu to tear it off so you can always see a list of the buffers.

:help buffers-menu

Is there a Vim script that simplifies using buffers with Vim?

Yes, try the Buffer Explorer , minibufexpl or bufmru plugins.

Is it possible to save and restore the buffer list across Vim sessions?

Yes. To save and restore the buffer list across Vim session, include the '%' flag in the 'viminfo' option. Note that if Vim is invoked with a filename argument, then the buffer list will not be restored from the last session. To use buffer lists across sessions, invoke Vim without passing filename arguments.

We can save different buffer list for different folders, by setting a local 'viminfo' file.

http://www.vim.org/scripts/script.php?script_id=441

The point is to overwrite the global setting by calling local setting after the 'viminfo' setting, for example.

set viminfo='1025,f1,%1024
call SetLocalOptions(".")

How do I remove all the entries from the buffer list?

You can remove all the entries in the buffer list by starting Vim with a file argument. You can also manually remove all the buffers using the ":bdelete" command.

What is a hidden buffer?

A hidden buffer is a buffer with some unsaved modifications and is not displayed in a window. Hidden buffers are useful, if you want to edit multiple buffers without saving the modifications made to a buffer while loading other buffers.

How do I load buffers in a window, which currently has a buffer with unsaved modifications?

By setting the option 'hidden', you can load a buffer in a window that currently has a modified buffer. Vim will remember your modifications to the buffer. When you quit Vim, you will be asked to save the modified buffers. It is important to note that, if you have the 'hidden' option set, and you quit Vim forcibly, for example using ":quit!", then you will lose all your modifications to the hidden buffers.

:help 'hidden'

Is it possible to unload or delete a buffer when it becomes hidden?

By setting the 'bufhidden' option to either 'hide' or 'unload' or 'delete', you can control what happens to a buffer when it becomes hidden. When 'bufhidden' is set to 'delete', the buffer is deleted when it becomes hidden. When 'bufhidden' is set to 'unload', the buffer is unloaded when it becomes hidden. When 'bufhidden' is set to 'hide', the buffer is hidden.

:help 'bufhidden'

How do I execute a command on all the buffers in the buffer list?

You can use the ":bufdo" command to execute a command on all the buffers in the buffer list.

:help :bufdo

When I open an existing buffer from the buffer list, if the buffer is already displayed in one of the existing windows, I want Vim to jump to that window instead of creating a new window for this buffer. How do I do this?

When opening a buffer using one of the split open buffer commands (:sbuffer, :sbnext), Vim will open the specified buffer in a new window. If the buffer is already opened in one of the existing windows, then you will have two windows containing the same buffer. You can change this behavior by setting the 'switchbuf' option to 'useopen'. With this setting, if a buffer is already opened in one of the windows, Vim will jump to that window, instead of creating a new window.

:help 'switchbuf'

What information is stored as part of a buffer?

Every buffer in the buffer list contains information about the last cursor position, marks, jump list, etc.

What is the difference between deleting a buffer and unloading a buffer?

When a buffer is unloaded, it is not removed from the buffer list. Only the file contents associated with the buffer are removed from memory. When a buffer is deleted, it is unloaded and removed from the buffer list. A deleted buffer becomes an 'unlisted' buffer.

Is it possible to configure Vim, by setting some option, to re-use the number of a deleted buffer for a new buffer?

No. Vim will not re-use the buffer number of a deleted buffer for a new buffer. Vim will always assign the next sequential number for a new buffer. The buffer number assignment is implemented this way, so that you can always jump to a buffer using the same buffer number. One method to achieve buffer number reordering is to restart Vim. If you restart Vim, it will re-assign numbers sequentially to all the buffers in the buffer list (assuming you have properly set 'viminfo' to save and restore the buffer list across Vim sessions).

:help buffers

How is a scratch (temporary) buffer created?

In any buffer (for example, after entering :new to create a new buffer), enter the following options to change the current buffer to a scratch buffer:

:setlocal buftype=nofile
:setlocal bufhidden=hide
:setlocal noswapfile

This creates a temporary buffer which is not associated with a file, which does not have an associated swap file, and which will be hidden when its window is closed. On exit, Vim discards any text in a scratch buffer without warning.

Also you can use scratch.vim for creating a scratch buffer.

How do I prevent a buffer from being added to the buffer list?

You can prevent a buffer from being added to the buffer list by resetting the 'buflisted' option.

:set nobuflisted

:help 'buflisted'

How do I determine whether a buffer is modified or not?

There are several ways to find out whether a buffer is modified or not. The simplest way is to look at the status line or the title bar. If the displayed string contains a '+' character, then the buffer is modified. Another way is to check whether the 'modified' option is set or not. If 'modified' is set, then the buffer is modified. To check the value of modified, use

:set modified?

You can also explicitly set the 'modified' option to mark the buffer as modified like this:

:set modified

:help 'modified'

How can I prevent modifications to a buffer?

You can prevent any modification to a buffer by re-setting the 'modifiable' option. To reset this option, use

:set nomodifiable

To again allow modifications to the buffer, use:

:set modifiable

:help 'modifiable'

How do I set options specific to the current buffer?

You can set Vim options which are specific to a buffer using the "setlocal" command. For example,

:setlocal textwidth=70

This will set the 'textwidth' option to 70 only for the current buffer. All other buffers will have the default or the previous 'textwidth' value.

How do I define mappings specific to the current buffer?

You can define mappings specific to the current buffer by using the keyword "<buffer>" in the map command. For example,

:map <buffer> ,w /[.,;]<CR>

:help map-local

How do I define abbreviations specific to the current buffer?

You can define abbreviations specific to the current buffer by using the keyword "<buffer>" in the :abbreviate command. For example,

:abb <buffer> FF for (i = 0; i < ; ++i)

:help abbreviate-local

Comments Edit

How does one execute a command in a new buffer? For example, execute :tj from the function you're on, in a new buffer window? This is very useful if you don't want to close the buffer you're on, but want to open a new buffer where the code is located.

You're confusing the terminology. What you're really asking for is not a new buffer, but a new window. You can get a new window in many ways. See :help opening-window for the basic commands. In addition, there are many commands (like :tj ) that also have a duplicate command that automatically splits the window first (like :stj ). -- Fritzophrenic 19:36, September 3, 2010 (UTC)

How can one take all open buffers and merge content into a single Buffer? I will try a small script to walk through the bufferlist yank'ing the data to a single buffer but if anyone has a neater way... then thanks in advance. -- Chumbawumba69 06:22, October 5, 2011 (UTC) (sorry if answered but could not find)

I don't think such an answer would belong in an FAQ, but you can probably accomplish this using the Bufdo command, combined with :yank . -- Fritzophrenic 17:39, October 5, 2011 (UTC)
Try uppercase register to keep appending conent like "Ayy and then put "ap. Try also articles on the wiki about the global command Power_of_g

Regarding the section on "creating" a scratch buffer, do those commands actually create a buffer, or do they simply transform an existing buffer into a scratch buffer? (I believe it's the latter.) -- Joe Sewell ( talk ) 19:59, April 8, 2014 (UTC)

Yes, you're right. I edited the section to clarify. JohnBeckett ( talk ) 11:50, April 9, 2014 (UTC)

[Oct 19, 2018] Vim Editing Multiple Files and Windowing Support Under Linux / UNIX

Dec 06, 2014 | www.cyberciti.biz

How do I open and edit multiple files on a VIM text editor running under Ubuntu Linux / UNIX-like operating systems to improve my productivity?

Vim offers multiple file editing with the help of windows. You can easily open multiple files and edit them using the concept of buffers.

Understanding vim buffer

A buffer is nothing but a file loaded into memory for editing. The original file remains unchanged until you write the buffer to the file using w or other file saving related commands.

Understanding vim window

A window is noting but a viewport onto a buffer. You can use multiple windows on one buffer, or several windows on different buffers. By default, Vim starts with one window, for example open /etc/passwd file, enter:
$ vim /etc/passwd

Open two windows using vim at shell promot

Start vim as follows to open two windows stacked, i.e. split horizontally :
$ vim -o /etc/passwd /etc/hosts
OR
$ vim -o file1.txt resume.txt
Sample outputs:

(Fig.01: split horizontal windows under VIM)

The -O option allows you to open two windows side by side, i.e. split vertically , enter:
$ vim -O /etc/passwd /etc/hosts How do I switch or jump between open windows?

This operation is also known as moving cursor to other windows. You need to use the following keys:

  1. Press CTRL + W + <Left arrow key> to activate left windows
  2. Press CTRL + W + <Right arrow key> to activate right windows
  3. Press CTRL + W + <Up arrow key> to activate to windows above current one
  4. Press CTRL + W + <Down arrow key> to activate to windows down current one
  5. Press CTRL-W + CTRL-W (hit CTRL+W twice) to move quickly between all open windows
How do I edit current buffer?

Use all your regular vim command such as i, w and so on for editing and saving text.

How do I close windows?

Press CTRL+W CTRL-Q to close the current windows. You can also press [ESC]+:q to quit current window.

How do I open new empty window?

Press CTRL+W + n to create a new window and start editing an empty file in it.

<="" in="" window="" current="" split="" i="" do="">

Press CTRL+W+ s to split current window in two.

How do I open exiting file in a new windows?

Press [ESC]+:new /path/to/file. This will create a new window and start editing file /path/to/file in it. For example, open file called /etc/hosts.deny, enter:
:new /etc/hosts.deny
Sample outputs:

(Fig.02: Create a new window and start editing file /etc/hosts.deny in it.)


(Fig.03: Two files opened in a two windows)
How do I resize Window?

You can increase or decrease windows size by N number. For example, increase windows size by 5, press [ESC] + 5 + CTRL + W+ + . To decrease windows size by 5, press [ESC]+ 5 + CTRL+ W + - .

Moving windows cheat sheet
Key combination Action
CTRL-W h move to the window on the left
CTRL-W j move to the window below
CTRL-W k move to the window above
CTRL-W l move to the window on the right
CTRL-W t move to the TOP window
CTRL-W b move to the BOTTOM window
How do I quit all windows?

Type the following command (also known as quit all command):
:qall
If any of the windows contain changes, Vim will not exit. The cursor will automatically be positioned in a window with changes. You can then either use ":write" to save the changes:
:write
or ":quit!" to throw them away:
:quit!

How do save and quit all windows?

To save all changes in all windows and quite , use this command:
:wqall
This writes all modified files and quits Vim. Finally, there is a command that quits Vim and throws away all changes:
:qall!

Opening multiple files with VI/VIM editor

To open multiple files, command would be same as is for a single file; we just add the file name for second file as well.

$ vi file1 file2 file 3

Now to browse to next file, we can use

$ :n

or we can also use

$ :e filename

Run external commands inside the editor

We can run external Linux/Unix commands from inside the vi editor, i.e. without exiting the editor. To issue a command from editor, go back to Command Mode if in Insert mode & we use the BANG i.e. '!' followed by the command that needs to be used. Syntax for running a command is,

$ :! command

An example for this would be

$ :! df -H

Searching for a pattern

To search for a word or pattern in the text file, we use following two commands in command mode,

Both of these commands are used for same purpose, only difference being the direction they search in. An example would be,

$ :/ search pattern (If at beginning of the file)

$ :/ search pattern (If at the end of the file)

Searching & replacing a pattern

We might be required to search & replace a word or a pattern from our text files. So rather than finding the occurrence of word from whole text file & replace it, we can issue a command from the command mode to replace the word automatically. Syntax for using search & replacement is,

$ :s/pattern_to_be_found/New_pattern/g

Suppose we want to find word "alpha" & replace it with word "beta", the command would be

$ :s/alpha/beta/g

If we want to only replace the first occurrence of word "alpha", then the command would be

$ :s/alpha/beta/

Using Set commands

We can also customize the behaviour, the and feel of the vi/vim editor by using the set command. Here is a list of some options that can be use set command to modify the behaviour of vi/vim editor,

Some other commands to modify vi editors are,

$ :colorscheme its used to change the color scheme for the editor. (for VIM editor only)

$ :syntax on will turn on the color syntax for .xml, .html files etc. (for VIM editor only)

[Nov 01, 2017] Vim character info by Tom Ryder

Mar 31, 2013 | sanctum.geek.nz

Posted on Vim will show you the decimal, octal, and hex index of the character under the cursor if you type ga in normal mode. Keying this on an ASCII a character yields the following in the status bar:

<a>  97,  Hex 61,  Octal 141

This information can be useful, but it's worth it to extend it to include some other relevant information, including the Unicode point and name of the character, its HTML entity name (if applicable), and any digraph entry method . This can be done by installing the characterize plugin by Tim Pope .

With this plugin installed, pressing ga over a yields a bit more information:

<a> 97, \141, U+0061 LATIN SMALL LETTER A

This really shines however when inspecting characters that are available as HTML entities, or as Vim digraphs, particularly commonly used characters like an EM DASH:

< -- > 8212, U+2014 EM DASH, ^K-M, &mdash;

Or a COPYRIGHT SYMBOL:

<©> 169, \251, U+00A9 COPYRIGHT SIGN, ^KCo, ^KcO, :copyright:, &copy;

Or as one of the eyes in a look of disapproval:

<ಠ> 3232, U+0CA0 KANNADA LETTER TTHA

Note that ga shows you all the Unicode information for the character, along with any methods to type it as a digraph, and an appropriate HTML entity if applicable.

If you work with multibyte characters a lot, whether for internationalization reasons or for typographical correctness in web pages, this may be very useful to you.

[Nov 01, 2017] Bash prompts by Tom Ryder

Jul 09, 2012 | sanctum.geek.nz

You can tell a lot about a shell user by looking at their prompt. Most shell users will use whatever the system's default prompt is for their entire career. Under many GNU/Linux distributions, this prompt includes the username, the hostname, and the current working directory, along with a $ sigil for regular users, and a # for root .

tom@sanctum:~$

This format works well for most users, and it's so common that it's often used in tutorials to represent the user's prompt in lieu of the single-character standard $ and # . It shows up as the basis for many of the custom prompt setups you'll find online.

Some users may have made the modest steps of perhaps adding some brackets around the prompt, or adding the time or date:

[10:11][tom@sanctum:~]$

Still others make the prompt into a grand multi-line report of their shell's state, or indeed their entire system, full of sound and fury and signifying way too much:

-(23:38:57)-(4 users)-(0.00, 0.02, 0.05)-
-(Linux sanctum 3.2.0-3-amd64 x86_64 GNU/Linux)-
[tom@sanctum:/dev/pts/2:/home/tom]{2}!?[MAIL]$

Then there are the BSD users and other minimalist contrarians who can't abide anything more than a single character cluttering their screens:

$

Getting your prompt to work right isn't simply a cosmetic thing, however. If done right and in a style consistent with how you work, it can provide valuable feedback on how the system is reacting to what you're doing with it, and also provide you with visual cues that could save you a lot of confusion -- or even prevent your making costly mistakes.

I'll be working in Bash. Many of these principles work well for Zsh as well, but Zsh users might want to read Steve Losh's article on his prompt setup first to get an idea of the syntactical differences.

Why is this important?

One of the primary differences between terminals and windowed applications is that there tends to be much less emphasis on showing metadata about the running program and its environment. For the most part, to get information about what's going on, you need to request it with calls like pwd , whoami , readlink , env , jobs , and echo $? .

The habit of keeping metadata out of the terminal like this unless requested may appeal to a sense of minimalism, but like a lot of things in the command line world, it's partly the olden days holding us back. When mainframes and other dinosaurs roamed the earth, terminal screens were small, and a long or complex prompt amounted to a waste of space and cycles (or even paper). In our futuristic 64-bit world, where tiny CRTs are a thing of the past and we think nothing of throwing gigabytes of RAM at a single process, this is much less of a problem.

Customising the prompt doesn't have many "best practices" to it like a lot of things in the shell; there isn't really a right way to do it. Some users will insist it's valuable to have the path to the terminal device before every prompt, which I think is crazy as I almost never need that information, and when I do, I can get it with a call to tty . Others will suggest that including the working directory makes the length of the prompt too variable and distracting, whereas I would struggle to work without it. It's worth the effort to design a prompt that reflects your working style, and includes the information that's consistently important to you on the system.

So, don't feel like you're wasting time setting up your prompt to get it just right, and don't be so readily impressed by people with gargantuan prompts in illegible rainbow colors that they copied off some no-name wiki. If you use Bash a lot, you'll be staring at your prompt for several hours a day. You may as well spend an hour or two to make it useful, or at least easier on the eyes.

The basics

The primary Bash prompt is stored in the variable PS1 . Its main function is to signal to the user that the shell is done with its latest foreground task, and is ready to accept input. PS1 takes the form of a string that can contain escape sequences for certain common prompt elements like usernames and hostnames, and which is evaluated at printing time for escape sequences, variables, and command or function calls within it.

You can inspect your current prompt definition with echo . If you're using GNU/Linux, it will probably look similar to this:

tom@sanctum:~$ echo $PS1
\u@\h:\w\$

PS1 works like any other Bash variable; you can assign it a new value, append to it, and apply substitutions to it. To add the text bash to the start of my prompt, I could do this:

tom@sanctum:~$ PS1=bash-"$PS1"
bash-tom@sanctum:~$

There are other prompts -- PS2 is used for "continued line" prompts, such as when you start writing a for loop and continue another part of it on a new line, or terminate your previous line with a backslash to denote the next line continues on from it. By default this prompt is often a right angle bracket > :

$ for f in a b c; do
>   do echo "$f"
> done

There are a couple more prompt strings which are much more rarely seen. PS3 is used by the select structure in shell scripts; PS4 is used while tracing output with set -x . Ramesh Natarajan breaks this down very well in his article on the Bash prompt . Personally, I only ever modify PS1 , because I see the other prompts so rarely that the defaults work fine for me.

As PS1 is a property of interactive shells, it makes the most sense to put its definitions in $HOME/.bashrc on GNU/Linux or BSD systems. It's likely there's already code in there doing just that. For Mac OS X, you'll likely need to put it into $HOME/.bash_profile instead.

Escapes

Bash will perform some substitutions for you in the first pass of its evaluation of your prompt string, replacing escape sequences with appropriate elements of information that are often useful in prompts. Below are the escape sequences as taken from the Bash man page:

\a     an ASCII bell character (07)
\d     the date in "Weekday Month Date" format (e.g., "Tue May 26")
\D{format}
       the format is passed to strftime(3) and the result is inserted into
       the prompt string; an empty format results in a locale-specific time
       representation. The braces are required
\e     an ASCII escape character (033)
\h     the hostname up to the first `.'
\H     the hostname
\j     the number of jobs currently managed by the shell
\l     the basename of the shell's terminal device name
\n     newline
\r     carriage return
\s     the name of the shell, the basename of $0 (the portion following
       the final slash)
\t     the current time in 24-hour HH:MM:SS format
\T     the current time in 12-hour HH:MM:SS format
\@     the current time in 12-hour am/pm format
\A     the current time in 24-hour HH:MM format
\u     the username of the current user
\v     the version of bash (e.g., 2.00)
\V     the release of bash, version + patch level (e.g., 2.00.0)
\w     the current working directory, with $HOME abbreviated with a tilde
       (uses the value of the PROMPT_DIRTRIM variable)
\W     the basename of the current working directory, with $HOME
       abbreviated with a tilde
\!     the history number of this command
\#     the command number of this command
\$     if the effective UID is 0, a #, otherwise a $
\nnn   the character corresponding to the octal number nnn
\\     a backslash
\[     begin a sequence of non-printing characters, which could be used to
       embed a terminal control sequence into the prompt
\]     end a sequence of non-printing characters

As an example, the default PS1 definition on many GNU/Linux systems uses four of these codes:

\u@\h:\w\$

The \! escape sequence, which expands to the history item number of the current command, is worth a look in particular. Including this in your prompt allows you to quickly refer to other commands you may have entered in your current session by history number with a ! prefix, without having to actually consult history :

$ PS1="(\!)\$"
(6705)$ echo "test"
test
(6706)$ !6705
echo "test"
test

Keep in mind that you can refer to history commands relatively rather than by absolute number. The previous command can be referenced by using !! or !-1 , and the one before that by !-2 , and so on, provided that you have left the histexpand option on.

Also of particular interest are the delimiters \[ and \] . You can use these to delimit sections of "non-printing characters", typically things like terminal control characters to do things like moving the cursor around, starting to print in another color, or changing properties of the terminal emulator such as the title of the window. Placing these non-printing characters within these delimiters prevents the terminal from assuming an actual character has been printed, and hence correctly manages things like the user deleting characters on the command line.

Colors

There are two schools of thought on the use of color in prompts, very much a matter of opinion:

If you agree more with the first opinion than the second, you can probably just skip to the next section of this article.

Printing text in color in terminals is done with escape sequences, prefixed with the \e character as above. Within one escape sequence, the foreground, background, and any styles for the characters that follow can be set.

For example, to include only your username in red text as your prompt, you might use the following PS1 definition:

PS1='\[\e[31m\]\u\[\e[0m\]'

Broken down, the opening sequence works as follows:

The terminating sequence is very similar, except it uses the 0 display attribute to reset the text that follows back to the terminal defaults.

The valid display attributes for 16-color terminals are:

Note that blink may not work on a lot of terminals, often by design, as it tends to be unduly distracting. It'll work on a linux console, though. Also keep in mind that for a lot of terminal emulators, by default "bright" colors are printed in bold.

More than one of these display attributes can be applied in one hit by separating them with semicolons. The below will give you underlined white text on a blue background, after first resetting any existing attributes:

\[\e[0;4;37;44m\]

It's helpful to think of these awkward syntaxes in terms of opening and closing, rather like HTML tags, so that you open before and then reset after all the attributes of a section of styled text. This usually amounts to printing \[\e[0m\] after each such passage.

These sequences are annoying to read and to type, so it helps to put commonly used styles into variables:

color_red='\[\e[31m\]'
color_blue='\[\e[34m\]'
color_reset='\[\e[0m\]'

PS1=${color_red}'\u'${color_reset}'@'${color_blue}'\h'${color_reset}

A more robust method is to use the tput program to print the codes for you, and put the results into variables:

color_red=$(tput setaf 1)
color_blue=$(tput setaf 4)

This may be preferable if you use some esoteric terminal types, as it queries the terminfo or termcap databases to generate the appropriate escapes for your terminal.

The set of eight colors -- or sixteen, depending on how you look at it -- can be extended to 256 colors in most modern terminal emulators with a little extra setup. The escape sequences are not very different, but their range is vastly increased to accommodate the larger palette.

A useful application for prompt color can be a quick visual indication of the privileges available to the current user. The following code changes the prompt to green text for a normal user, red for root , and yellow for any other user attained via sudo :

color_root=$(tput setaf 1)
color_user=$(tput setaf 2)
color_sudo=$(tput setaf 3)
color_reset=$(tput sgr0)

if (( EUID == 0 )); then
    PS1="\\[$color_root\\]$PS1\\[$color_reset\\]"
elif [[ $SUDO_USER ]]; then
    PS1="\\[$color_sudo\\]$PS1\\[$color_reset\\]"
else
    PS1="\\[$color_user\\]$PS1\\[$color_reset\\]"
fi

Otherwise, you could simply use color to make different regions of your prompt more or less visually prominent.

Variables

Provided the promptvars option is enabled, you can reference Bash variables like $? to get the return value of the previous command in your prompt string. Some people find this valuable to show error codes in the prompt when the previous command given fails:

$ shopt -s promptvars
$ PS1='$? \$'
1 $ echo "test"
test
0 $ fail
-bash: fail: command not found
127 $

The usual environment variables like USER and HOME will work too, though it's preferable to use the escape sequences above for those particular variables. Note that it's important to quote the variable references as well, so that they're evaluated at runtime, and not during the assignment itself.

Commands

If the information you want in your prompt isn't covered by any of the escape codes, you can include the output of commands in your prompt as well, using command substitution with the syntax $(command) :

$ PS1='[$(uptime) ]\$ '
[ 01:21:59 up 7 days, 13:04,  7 users, load average: 0.30, 0.40, 0.36 ]$

This requires the promptvars option to be set, the same way variables in the prompt do. Again, note that you need to use single quotes so that the command is run when the prompt is being formed, and not immediately as part of the assignment.

This can include pipes to format the data with tools like awk or cut , if you only need a certain part of the output:

$ PS1='[$(uptime | cut -d: -f5) ]\$ '
[ 0.36, 0.34, 0.34 ]$

For clarity, during prompt setup in .bashrc , it makes sense to use functions instead for reasonably complex commands:

prompt_load() {
    uptime | cut -d: -f5
}
PS1='[$(prompt_load) ]'$PS1

Note that as a normal part of command substitution, trailing newlines are stripped from the output of the command, so here the output of uptime appears on a single line.

A common usage of this pattern is showing metadata about the current directory, particularly if it happens to be a version control repository or working copy; you can use this syntax with functions to show the type of version control system, the current branch, and whether any changes require committing. Working with Git, Mercurial, and Subversion most often, I include the relevant logic as part of my prompt function .

When appended to my PS1 string, $(prompt vcs) gives me prompts that look like the following when I'm in directories running under the appropriate VCS. The exclamation marks denote that there are uncommitted changes in the repositories.

[tom@conan:~/.dotfiles](git:master!)$
[tom@conan:~/Build/tmux](svn:trunk)$
[tom@conan:~/Build/vim](hg:default!)$

In general, where this really shines is adding pieces to your prompt conditionally , to make them collapsible. Certain sections of your prompt therefore only show up if they're relevant. This snippet, for example, prints the number of jobs running in the background of the current interactive shell in curly brackets, but only if the count is non-zero:

prompt_jobs() {
    local jobc
    while read -r _; do
        ((jobc++))
    done < <(jobs -p)
    if ((jobc > 0)); then
        printf '{%d}' "$jobc"
    fi
}

It's important to make sure that none of what your prompt does takes too long to run; an unresponsive prompt can make your terminal sessions feel very clunky.

Note that you can also arrange to run a set of commands before the prompt is evaluated and printed, using the PROMPT_COMMAND . This tends to be a good place to put commands that don't actually print anything, but that do need to be run before or after each command, such as operations working with history :

PROMPT_COMMAND='history -a'
Switching

If you have a very elaborate or perhaps even computationally expensive prompt, it may occasionally be necessary to turn it off to revert to a simpler one. I like to handle this by using functions, one of which sets up my usual prompt and is run by default, and another which changes the prompt to the minimal $ or # character so often used in terminal demonstrations. Something like the below works well:

prompt_on() {
    PS1="$color_prompt"'\u@\h:\w'"$(prompt_jobs)"'\$'"${color_reset}"' '
}
prompt_off() {
    PS1='\$'
}
prompt_on

You can then switch your prompt whenever you need to by typing prompt_on and prompt_off .

This can also be very useful if you want to copy text from your terminal into documentation, or into an IM or email message; it removes your distracting prompt from the text, where it would otherwise almost certainly differ from that of the user following your instructions. This is also occasionally helpful if your prompt does not work on a particular machine, or the machine is suffering a very high load average that means your prompt is too slow to load.

Further reading

Predefined prompt strings are all over the web, but the above will hopefully enable you to dissect what they're actually doing more easily and design your own. To take a look at some examples, the relevant page on the Arch Wiki is a great start. Ramesh Natarajan over at The Geek Stuff has a great article with some examples as well, with the curious theme of making your prompt as well-equipped as Angelina Jolie .

Finally, please feel free to share your prompt setup in the comments (whether you're a Bash user or not). It would be particularly welcome if you explain why certain sections of your prompt are so useful to you for your particular work.

[Nov 01, 2017] Actually using ed by Tom Ryder

Notable quotes:
"... Update 2016: Recent Hacker News discussion has reminded me of my long-standing mistake in asserting that ed(1) is included in every Unix and Unix-like system's base installation. This is not even close to true–many others exclude it–and the claim has been removed, which I should have done years ago. ..."
"... Thanks to A. Pedro Cunha for a couple of fixes to show correct typical output. ..."
Jun 17, 2012 | sanctum.geek.nz

The classic ed editor is a really good example of a sparse, minimal, standard Unix tool that does one thing, and does it well. Because there are so many good screen-oriented editors for Unix, there's seldom very much call for using ed , unless you're working on very old or very limited hardware that won't run anything else.

However, if part of the reason you use vi is because you think it will always be there (it may not be), then you should learn ed too. If your terminal is broken and neither vi nor nano will work, or you break it some other way, your choices may well be between cat and ed . Or even the grand heresy of sed -i

Not a friendly editor

Even more than its uppity grandchild ex / vi , ed has developed a reputation as terse and intimidating to newcomers. When you type ed at the command line, nothing happens, and the only error message presented by default is ? . If you're reading this, it's likely your first and only experience with ed went something like this:

$ ed
help
?
h
Invalid command suffix
?
?
^C
?
exit
?
quit
?
^Z
$ killall ed
$ vi

So, ed is not a terribly intuitive editor. However, it's not nearly as hard to learn as it might seem, especially if you're a veteran vi user and thereby comfortable with the ex command set. With a little practice, you can actually get rather quick with it; there's an elegance to its almost brutal simplicity.

It's also very interesting to learn how ed works and how to use it, not just because it might very well be useful for you one day, but because it occupies an important position in the heritage of the sed stream editor, the ex line editor, the vi visual editor, the grep tool, and many other contexts.

Why is ed so terse?

When ed was developed, the usual method of accessing a Unix system was via a teletype device, on which it wouldn't have been possible to use a screen-oriented editor like vi . Similarly, modems were slow, and memory was precious; using abbreviated commands and terse error messages made a lot of sense, because the user would otherwise be wasting a lot of time waiting for the terminal to react to commands, and didn't have a whole lot of memory to throw around for anything besides the buffer of text itself.

Of course, this is almost a non-issue for most Unix-like systems nowadays, so one of the first things we'll do is make ed a little bit less terse and more user-friendly.

Error messages

Start ed up the usual way:

$ ed

We'll start by deliberately doing something wrong. Type b and press Enter:

b
?

There's that tremendously unhelpful ? again. But if you press h , you can see what went wrong:

h
Unknown command

Of course, since it's the future now, we can spare the terminal cycles to have ed print the error message for us every time. You can set this up by pressing H :

H
b
?
Unknown command

That's a bit more useful, and should make things easier.

Quitting

You can quit ed with q . Go ahead and do that. If you had unsaved changes in a buffer, you could type Q to quit unconditionally. Repeating yourself works too:

q
?
Warning: buffer modified
q
Command prompt

Let's invoke ed again, but this time we'll use the -p option to specify a command prompt :

$ ed -p\*
*

We'll use that from now on, which will make things clearer both for interpreting this tutorial and for remembering whether we're in command mode, or entering text. It might even be a good idea to make it into a function :

$ ed() { command ed -p\* "$@" ; }
Basic text input

We'll start by adding a couple of lines of text to the new buffer. When you start ed with no filename, it starts an empty buffer for you, much like vi does.

Because there are no lines at all at present, press a to start adding some at the editor's current position:

*a
Start typing a few lines.
Anything you want, really.
Just go right ahead.
When you're done, just type a period by itself.
.

That's added four new lines to the buffer, and left the editor on line 4. You can tell that's the case because typing p for print, just by itself, prints the fourth line:

*p
When you're done, just type a period by itself.

A little more useful is n (or pn in some versions), which will show both the line number and the contents of the line:

*n
4       When you're done, just type a period by itself.

So just like in ex , the current line is the default for most commands. You can make this explicit by referring to the current line as . :

*.n
4       When you're done, just type a period by itself.

You can move to a line just by typing its number, which will also print it as a side effect:

*3
Just go right ahead.
*.n
3       Just go right ahead.

Pressing a like you did before will start inserting lines after the current line:

*a
Entering another line.
.
*n
4       Entering another line.

Pressing i will allow you to insert lines before the current line:

*i
A line before the current line.
.
*n
4       A line before the current line.

You can replace a line with c :

*c
I decided I like this line better.
.
*n
4       I decided I like this line better.

You can delete lines with d :

*6d

And join two or more lines together with j :

*1,2j

You can prepend an actual line number to any of these commands to move to that line before running the command on it:

*1c
Here's a replacement line.
.
*1n
1       Here's a replacement line.

For most of these commands, the last line to be changed will become the new current line.

Ranges

You can select the entire buffer with 1,$ or , for short ( % works too):

*,p
Here's a replacement line.
Just go right ahead.
I decided I liked this line better.
Entering another line.

Or a limited range of specific lines:

*2,3p
Just go right ahead.
I decided I liked this line better.

These ranges can include a reference to the current line with . :

*2
Just go right ahead.
*.,4p
Just go right ahead.
I decided I liked this line better.
Entering another line.

They can also include relative line numbers, prefixed with + or - :

*2
*-1,+1p
Here's a replacement line.
Just go right ahead.
I decided I liked this line better.

You can drop a mark on a line with k followed by a lowercase letter such as a , and you're then able to refer to it in ranges as 'a :

*3ka
*'ap
I decided I liked this line better.
Moving and copying

Move a line or range of lines to after a target line with m :

*1,2m$
*,p
I decided I liked this line better.
Entering another line.
Here's a replacement line.
Just go right ahead.

Copy lines to after a target line with t :

*2t4
*,p
I decided I liked this line better.
Entering another line.
Here's a replacement line.
Just go right ahead.
Entering another line.
Regular expressions

You can select lines based on classic regular expressions with the g operator. To print all lines matching the regular expression /re/ :

*g/re/p
Here's a replacement line.

(Hmm, where have I seen that command before?)

You can invert the match to work with lines that don't match the expression with v :

*v/re/p
I decided I liked this line better.
Entering another line.
Just go right ahead.
Entering another line.

Just like numbered line ranges, ranges selected with regular expressions can have other operations applied to them. To move every line containing the expression /re/ to the bottom of the file:

*g/re/m$
*,p
I decided I liked this line better.
Entering another line.
Just go right ahead.
Entering another line.
Here's a replacement line.
Searching

You can move to the next line after the current one matching a regular expression with / . Again, this will print the line's contents as a side effect.

*/like
I decided I like this line better.

You can search backward with ? :

*?Here
Here's a replacement line.
Substituting

You can substitute for the first occurrence per line of an expression within a range of lines with the s command:

*1s/i/j
I decjded I like this line better.

You can substitute for all the matches on each line by adding the /g suffix:

*1s/i/j/g
*p
I decjded I ljke thjs ljne better.
Reading and writing

You can write the current buffer to a file with w , which will also print the total number of bytes written:

*w ed.txt
129

Having done this once, you can omit the filename for the rest of the session:

*w
129

Like most ed commands, w can be prefixed with a range to write only a subset of lines to the file. This would write lines 1 to 4 to the file ed.txt :

*1,4w ed.txt
102

You can use W to append to a file, rather than replace it. This would write lines 3 to 5 to the end of the file ed.txt :

*3,5W
71

You can read in the contents of another file after the current line (or any other line) with r . Again, this will print the number of bytes read.

*r /etc/hosts
205

The output of a command can be included by prefixing it with ! :

*r !ps -e
5571

If you just want to load the contents of a file or the output of a command into the buffer, replacing what's already there, use e , or E if you've got an unmodified buffer and don't care about replacing it:

*E ed.txt
173

If you don't like seeing the byte counts each time, you can start ed with the -s option for "quiet mode".

Familiar syntax

Almost all of the above command sets will actually be familiar to vi users who know a little about ex , or Vimscript in Vim. It will also be familiar to those who have used sed at least occasionally.

Once you get good with ed , it's possible you'll find yourself using it now and then to make quick edits to files, even on systems where your favourite screen-based editor will load promptly. You could even try using ex .

Update 2016: Recent Hacker News discussion has reminded me of my long-standing mistake in asserting that ed(1) is included in every Unix and Unix-like system's base installation. This is not even close to true–many others exclude it–and the claim has been removed, which I should have done years ago.

Thanks to A. Pedro Cunha for a couple of fixes to show correct typical output.

[Nov 01, 2017] Advanced Vim registers by Tom Ryder

Oct 24, 2012 | sanctum.geek.nz

Posted on Registers in Vim are best thought of as scratch spaces for text, some of which are automatically filled by the editor in response to certain actions. Learning how to use registers fluently has a lot of subtle benefits, although it takes some getting used to because the syntax for using them is a little awkward.

If you're reasonably fluent with Vim by now, it's likely you're already familiar with the basic usage of the 26 named registers , corresponding to the letters of the alphabet. These are commonly used for recording macros ; for example, to record a series of keystrokes into register a , you might start recording with qa , and finish with q ; your keystrokes could then be executed with @a .

Similarly, we can store text from the buffer itself rather than commands in these registers, by prepending "a to any command which uses a register, such as the c , d , and y commands:

Like many things in Vim, there's a great deal more functionality to registers for those willing to explore.

Note that here I'll be specifically ignoring the * , + , and ~ registers; that's another post about the generally unpleasant business of making Vim play nice with system clipboards. Instead, I'll be focussing on stuff that only applies within a Vim session. All of this is documented in :help registers .

Capital registers

Yanking and deleting text into registers normally replaces the previous contents of that register. In some cases it would be preferable to append to a register, for example while cherry-picking different lines from the file to be pasted elsewhere. This can be done by simply capitalizing the name of the register as it's referenced:

This works for any context in which an alphabetical register can be used. Similarly, to append to a macro already recorded in register a , we can start recording with qA to add more keystrokes to it.

Viewing register contents

A good way to start getting a feel for how all the other registers work is to view a list of them with their contents during an editing session with :registers . This will show the contents of any register used in the editing session. It might look something like this, a little inscrutable at first:

:registers
--- Registers ---

":   register
"%   advanced-vim-registers.markdown
"/   Frij

The first column contains the name of the register, and the second its contents. The contents of any of these registers can be pasted into the buffer with "ap , where a is the name of any of them. Note that there are considerably more registers than just the named alphabetical ones mentioned above.

Unnamed register

The unnamed register is special in that it's always written to in operations, no matter whether you specified another register or not. Thus if you delete a line with dd , the line's contents are put into the unnamed register; if you delete it with "add , the line's contents are put into both the unnamed register and into register a .

If you need to explicitly reference the contents of this register, you can use " , meaning you'd reference it by tapping " twice: "" . One handy application for this is that you can yank text into the unnamed register and execute it directly as a macro with @" .

Man, and you thought Perl looked like line noise.

Black hole register

Another simple register worth mentioning is the black hole register , referenced with "_ . This register is special in that everything written to it is discarded. It's the /dev/null of the Vim world; you can put your all into it, and it'll never give anything back. A pretty toxic relationship.

This may not seem immediately useful, but it does come in handy when running an operation that you don't want to clobber the existing contents of the unnamed register. For example, if you deleted three lines into the unnamed register with 3dd with the intent of pasting them elsewhere with p , but you wanted to delete another line before doing so, you could do that with "_dd ; line gone, and no harm done.

Numbered registers

The read-only registers 0 through 9 are your "historical record" registers. The register 0 will always contain the most recently yanked text , but never deleted text; this is handy for performing a yank operation, at least one delete operation, and then pasting the text originally yanked with "0p .

The registers 1 through 9 are for deleted text , with "1 referencing the most recently deleted text, "2 the text deleted before that, and so on up to "9 .

The small delete register

This read-only register, referenced by "- , stores any text that you deleted or changed that was less than one line in length, unless you specifically did so into some other named register. So if you just deleted three characters with 3x , you'll find it in here.

Last inserted text register

The read-only register ". contains the text that you last inserted. Don't make the mistake of using this to repeat an insert operation, though; just tap . for that after you leave insert mode, or have the foresight to prepend a number to your insert operation; for example, 6i .

Filename registers

The read-only register "% contains the name of the current buffer's file. Similarly, the "# register contains the name of the alternate buffer's file.

Command registers

The read-only register ": contains the most recently executed : command, such as :w or :help . This is likely only of interest to you if you're wanting to paste your most recent command into your Vim buffer. For everything else, such as repeating or editing previous commands, you will almost certainly want to use the command window .

Search registers

The read-only register / contains the most recent search pattern; this can be handy for inserting the search pattern on the command line, by pressing Ctrl-R and then / -- very useful for performing substitutions using the last search pattern.

Expression register

Here's the black sheep of the bunch. The expression register = is used to treat the results of arbitrary expressions in register context. What that means in actual real words is that you can use it as a calculator, and the result is returned from the register.

Whenever the expression register is referenced, the cursor is put on the command line to input an expression, such as 2+2 , which is ended with a carriage return.

This means in normal mode you can type "=2+2<Enter>p , and 4 will be placed after the cursor; in insert or command mode you can use Ctrl-R then =2+2<Enter> for the same result. If you don't find this syntax as impossibly awkward as I do, then this may well suit you for quick inline calculations personally, I'd drop to a shell and bust out bc for this.

Knowing your registers well isn't as profound a productivity boost as squelching a few of the other Vim anti-patterns , but it can certainly save you some of the annoyance of lost text. Posted in Vim Tagged advanced , black hole , expression , named , numbered , read-only , registers , unnamed Start Vim with splits Posted on September 11, 2012 by Tom Ryder If you want to call Vim to edit more than one file, you can add an option to the command line to open all of the buffers in split windows on startup:

[Oct 31, 2017] Vim filename completion

Oct 31, 2017 | sanctum.geek.nz

Posted on February 1, 2012 by Tom Ryder The autocompletion for filenames in Vim in command mode is very useful, but by default it's a bit confusing for people accustomed to tab completion in Bash because it doesn't quite work the same way. Pressing Tab will complete the filename to the first match, and subsequent presses will not elicit any list of possible completions that might otherwise be expected; for that, by default you need to press Ctrl+D rather than Tab. Tab then tab

Fortunately, this is easily changed by using Vim's wildmenu , in an appropriate mode. Set the following options in your .vimrc :

set wildmenu
set wildmode=longest,list

You should now find that when you complete filenames after commands like :w and :e , the paths expand in a similar manner to the way they do in the shell. If you'd prefer to only press Tab once to get both the longest matching unique string and a list of possible complete matches, that's possible to arrange in both Bash and Vim as well.

Ignoring file types

There are probably certain filetypes in your directories that you'll never want to edit with Vim. There's hence no point in making them options for the autocompletion, and you can exclude them by pattern to make searching for the right file a bit quicker. This is done using the wildignore pattern. I use the following settings:

set wildignore+=*.a,*.o
set wildignore+=*.bmp,*.gif,*.ico,*.jpg,*.png
set wildignore+=.DS_Store,.git,.hg,.svn
set wildignore+=*~,*.swp,*.tmp
Compatibility

For the sake of keeping my .vimrc consistent and compatible on both older and newer machines, I like to wrap these options in a conditional block checking that the wildmenu feature is actually available:

" Wildmenu
if has("wildmenu")
    set wildignore+=*.a,*.o
    set wildignore+=*.bmp,*.gif,*.ico,*.jpg,*.png
    set wildignore+=.DS_Store,.git,.hg,.svn
    set wildignore+=*~,*.swp,*.tmp
    set wildmenu
    set wildmode=longest,list
endif
Insert mode

You can also complete file paths and names in insert mode with Ctrl+X Ctrl+F. It can be handy to map this to Tab if you don't use it for anything else:

inoremap <Tab> <C-X><C-F>

[Oct 31, 2017] Safely editing as root

Oct 31, 2017 | sanctum.geek.nz

Posted on February 2, 2012 by Tom Ryder Certain files on a UNIX-like system, such as /etc/passwd and /etc/sudoers , are integral for managing login and authentication, and it's thus necessary to be very careful while editing them using sudo not to accidentally leave them in a corrupted state, or to allow others to edit them at the same time as you. In the worst case scenario it's possible to lock yourself out of a system or out of root privileges in doing this, and things can only be fixed via physical access to the server or someone who knows the actual root password, which you may not necessarily know as a sudo user.

You should therefore never edit /etc/passwd , /etc/group , or /etc/sudoers by simply invoking them in your editor of choice. A set of simple utilities exist to help you make these edits safely.

vipw and vigr

If you want to safely edit the /etc/passwd file, for which you'll need to have root privileges, you should use the vipw tool. It doesn't require an argument.

# vipw

This will load a temporary copy of the file into your $EDITOR , and allow you to make changes. If all is well after you save and quit, you'll see a message like:

You have modified /etc/passwd.
You may need to modify /etc/shadow for consistency.
Please use the command 'vipw -s' to do so.

If you've made changes which might require changing something in the /etc/shadow file, you should follow these instructions too.

The command to edit groups, vigr , works in much the same way:

# vigr
visudo

The analogous tool for editing the /etc/sudoers file is visudo . This file not only does the necessary lock and file corruption checking as vipw does, it also does some basic checking of the syntax of the file after you save it.

# visudo

If the changes you make to this file work correctly, you'll simply be returned to your prompt. However, if you've made some sort of edit that means sudo won't be able to correctly parse the file, you'll get warned and prompted for an appropriate action:

visudo: >>> /etc/sudoers: syntax error near line 28 <<<
visudo: >>> /etc/sudoers: syntax error near line 29 <<<
visudo: >>> /etc/sudoers: syntax error near line 29 <<<
What now?

If you press ? here and then Enter, you'll get a list of the actions you can take:

Options are:
(e)dit sudoers file again
e(x)it without saving changes to sudoers file
(Q)uit and save changes to sudoers file (DANGER!)

You'll probably want the first one, to edit your changes again and make them work properly, but you may want to hose them and start again via the second option. You should only choose the third if you absolutely know what you're doing.

sudoedit

In general, you can edit root-owned files using sudoedit , or sudo -e , which will operate on temporary copies of the file and overwrite the original if changes are detected:

$ sudo -e /etc/network/interfaces

This has the added bonus of preserving all of your environment variables for the editing session, which may not be the case when invoking an editor and file via sudo . This turns out to be handy for newer versions of sudo which do not preserve the user's $HOME directory by default, meaning that configuration files for your editor, such as .vimrc , might not be read.

[Oct 31, 2017] Faster Vim search/replace by Tom Ryder

Apr 29, 2012 | sanctum.geek.nz

Entering search patterns and replacement strings in Vim can sometimes be a pain, particularly if the search or replacement text is already available in a register or under the cursor. There are a few ways to make working with search and replace in Vim quicker and less cumbersome for some common operations, and thereby save a bit of error-prone typing. Insert contents of a register

As in command mode or insert mode, you can insert the contents of any register by pressing Ctrl+R and then the register key. For example, to directly insert the contents of register a , you can type Ctrl+R and then a while typing a search pattern or replacement string.

Reference contents of a register

Similarly, if you want to use the contents of a register in a pattern or replacement but don't want to directly insert it, you can instead reference the contents of register a with \=@a :

:s/search/\=@a/

Both of the above tips work for both the search and replacement patterns, and for special registers like " (default unnamed register) and / (last searched text) as well as the alphabetical ones.

Insert word under cursor

If you happen to be hovering over a word that you want to use as as a search or replacement string, as a special case of the above you can do so by typing Ctrl+R and then Ctrl+W for a normal word, or Ctrl+R and then Ctrl+A for a space-delimited word.

Empty search string

You can use the previous search as a search pattern or replacement string by including it from the special / register, in the same way as any other register above, by inserting it with Ctrl+R and then / , or representing it with \=@/ . There's a convenient shorthand for this however in just using an empty search string:

:s//replacement/

This will replace all occurences of the previous search string with replacement . It turns out to be a particularly convenient shorthand when searching for words by pressing * or # .

[Oct 31, 2017] Advanced Vim macros by Tom Ryder

Notable quotes:
"... macros are just text ..."
"... Thanks to user bairui for suggesting a safer alternative for yanking macro lines from buffers, which I've changed. He's written a whole blog post replying to this one. It's a good read if you're interested in going in to even more depth about when to use macros in Vim. ..."
Jun 04, 2012 | sanctum.geek.nz

Vim's massive command set in both normal and command mode makes the concept of a macro especially powerful. Most Vim users, if they ever use macros at all, will perhaps quickly record an edit to one line, starting with qq and finishing with q , executing with @q , and otherwise never give the concept much thought.

For slightly more advanced Vim users, macros may be more frequently useful, but they perhaps still believe that macros are a niche Vim function unto themselves, and not really open to the deft manipulation of text that pretty much everything else in Vim is.

As is typical in Vim, the rabbit hole of functionality goes much deeper than most users will ever plumb.

Vanilla Vim macros

Suppose I had a plaintext table loaded into a Vim buffer containing the name, subject matter expertise, birth year, and nationality of a few well-known programmers:

Stallman  Richard GNU 1953  USA
Wall  Larry   Perl  1954  USA
Moolenar  Bram  Vim 1961  Netherlands
Tridgell  Andrew  Samba  1967  Australia
Matsumoto  Yukihiro  Ruby  1965  Japan
Ritchie  Dennis  C  1941  USA
Thompson  Ken  Unix  1943  USA

Actually, that's kind of untidy. Let's start by formatting it a bit, by running it through Unix's column tool.

:%!column -t

Stallman   Richard   GNU    1953  USA
Wall       Larry     Perl   1954  USA
Moolenar   Bram      Vim    1961  Netherlands
Tridgell   Andrew    Samba  1967  Australia
Matsumoto  Yukihiro  Ruby   1965  Japan
Ritchie    Dennis    C      1941  USA
Thompson   Ken       Unix   1943  USA

May as well sort it by surname too:

:%!sort -k1

Matsumoto  Yukihiro  Ruby   1965  Japan
Moolenar   Bram      Vim    1961  Netherlands
Ritchie    Dennis    C      1941  USA
Stallman   Richard   GNU    1953  USA
Thompson   Ken       Unix   1943  USA
Tridgell   Andrew    Samba  1967  Australia
Wall       Larry     Perl   1954  USA

That's better.

Now, suppose we've got the task of replacing the fourth column of this table with the approximate age of the person, which we can get naturally enough by sutracting their birth year from the current year. This is a little awkward to do in pure ex, so we'll record a macro for doing it on one line.

Experimenting a bit, we find that the following works well:

03wdei^R=2012-^R"^M^[0j

Broken down, this does the following:

So we record it into a macro a (to stand for "age", no other reason) as we fix up the first line:

qa03wdei^R=2012-^R"^M^[0jq

Matsumoto  Yukihiro  Ruby   47  Japan
Moolenar   Bram      Vim    1961  Netherlands
Ritchie    Dennis    C      1941  USA
Stallman   Richard   GNU    1953  USA
Thompson   Ken       Unix   1943  USA
Tridgell   Andrew    Samba  1967  Australia
Wall       Larry     Perl   1954  USA

This now means that for each line, we can run the macro by just tapping @a a few times:

Matsumoto  Yukihiro  Ruby   47  Japan
Moolenar   Bram      Vim    51  Netherlands
Ritchie    Dennis    C      71  USA
Stallman   Richard   GNU    59  USA
Thompson   Ken       Unix   69  USA
Tridgell   Andrew    Samba  45  Australia
Wall       Larry     Perl   58  USA

That's all pretty stock-standard macro stuff that you'll likely have learned in other tutorials. The only thing that's slightly voodoo (and certainly not vi-compatible) is the arithmetic done with the special = register. You can read about that in :help @= , if you're curious.

Repeating Vim macros

As a first very simple hint, if you're running a macro several times, don't forget that you can prepend a count to it; in our case, 6@a would have fixed up all the remaining lines. To take advantage of this, it's good practice to compose your macros so that they make sense when run multiple times; in the example above, note that the end of the macro is moving down onto the next line, ready to run the macro again if appropriate.

Similarly, if you've already run a macro once, you can run the same one again by just tapping the @ key twice, @@ . This repeats the last run macro. Again, you can prepend a count to this, @a5@@ .

The true nature of Vim macros

The registers that hold macros are the same registers that you probably use more frequently for operations like deleting, yanking, and pasting. Running a macro is simply instructing Vim to take the contents of a register and execute them as keystrokes, as if you were actually typing them. Thinking about macros this way has a couple of interesting consequences.

First of all, it means you needn't restrict yourself to the single-keystroke vi commands for Vim when you compose macros. You can include ex commands as well, for example to run a substitution during a macro:

qb:s/foo/bar/g^Mq
@b

Secondly, and more interestingly, all of the operations that you can apply to registers in general work with what we normally call macros, with the old standards, delete, yank, and paste. You can test this with the example macro demonstrated above, by typing "ap , which will dump the raw text straight into the buffer. Also like other registers, it'll show up in the output of the :registers command.

All this means is that like everything else in Vim, macros are just text , and all of Vim's clever tools can be used to work with them.

Editing Vim macros in a buffer

If you've used macros even a little bit you'll be very familiar with how frustrating they are to record. For some reason, as soon as you press qa to start recording a macro into register a , your normal fluency with Vim commands goes out the window and you keep making mistakes that will make the macro unsuitable to apply.

So, don't compose macros on the fly. Just stop doing it. I recommend that if a macro is more than three keystrokes, you should compose it directly in a scratch Vim buffer so that you can test it iteratively.

Here's an example using the macro above; suppose I realise partway through writing it that I made a mistake in typing 2011 instead of 2012. I finish recording the rest of the macro anyway, and dump the broken keystrokes into a new scratch buffer:

:enew
"ap

This gives me the contents of the macro in plain text in the buffer:

qa03wdei^R=2011-^R"^M^[0jq

So now all I have to do is change that bad year to 2012, and then yank the whole thing back into register a :

^"ay$

Now I can test it directly with @a on the appropriate file, and if it's still wrong, I just jump back to my scratch buffer and keep fixing it up until it works.

One potential snag here is that you have to enter keystrokes like Ctrl+R as literal characters, but once you know you can enter any keystroke in Vim literally in insert or command mode by prefixing it with Ctrl+V, that isn't really a problem. So to enter a literal Ctrl+R in insert mode, you type Ctrl+V, then Ctrl+R.

Running a Vim macro on a set of lines

It's occasionally handy to be able to run a macro that you've got ready on a specific subset of lines of the file, or perhaps just for every line. Fortunately, there's a way to do this, too.

Using the :normal command, you're able to run macros from the ex command line:

:normal @a

All it takes is prefixing this with any sort of range definition to allow you to run a macro on any set of lines that you're able to define.

Run the macro on each line of the whole buffer:

:% normal @a

Between lines 10 and 20:

:10,20 normal @a

On the lines in the current visual selection:

:'<,'> normal @a

On the lines containing the pattern vim:

:g/vim/ normal @a

When you get confident using this, :norm is a nice abbreviation to use.

Moving a Vim macro into a function

For really useful macros of your own devising, it's occasionally handy to put it into a function for use in scripts or keystroke mappings. Here again the :normal command comes in handy.

Suppose I wanted to keep the age calculation macro defined above for later use on spreadsheets of this kind. I'd start by dumping it into a new buffer:

:enew
"ap

The macro appears as raw text:

03wdei^R=2012-^R"^M^[0j

I prefix it with a :normal call, and wrap a function definition around it:

function! CalculateAge()
    normal 03wdei^R=2012-^R"^M^[0j 
endfunction

Then all I need to do is include that in a file that gets loaded during Vim's startup, possibly just .vimrc . I can call it directly from ex:

:call CalculateAge()

But given that I wanted it to be a quick-access macro, maybe it's better to bind it to \a , or whatever your chosen <leader> character is:

nnoremap <leader>a :call CalculateAge()<CR>
Saving a Vim macro

If you want to have a macro always available to you, that is, always loaded into the appropriate register at startup, that can be done in your .vimrc file with a call to let to fill the register with the literal characters required:

let @a='03wdei^R=2012-^R"^M^[0j'
Appending extra keystrokes to a Vim macro

If you just want to tack extra keystrokes onto an existing macro and don't care to edit it in a Vim buffer, you can do that by recording into it with its capital letter equivalent. So, if you wanted to add more keystrokes into the register b , start recording with qB , and finish with the usual q .

Recursive Vim macros

If you're crazy enough to need this, and I never have, there's an excellent Vim Tip for it. But personally, I think if you need recursion in your text processing then it's time to bust out a real programming language and not Vimscript to solve your problem.

If the issue for which you think you need recursion is running a macro on every line of a buffer with an arbitrary number of lines, then you don't need recursion; just record a one-line version of the macro and call it with :% normal @a to run it on every line.

Vim macro gotchas

Here are a few gotchas which will save you some frustration if you know about them ahead of time:

Thanks to user bairui for suggesting a safer alternative for yanking macro lines from buffers, which I've changed. He's written a whole blog post replying to this one. It's a good read if you're interested in going in to even more depth about when to use macros in Vim.

[Oct 31, 2017] Local .vimrc files by Tom Ryder

May 26, 2012 | sanctum.geek.nz

If you can, it's a good idea to set up your .vimrc file using conditionals so that it's compatible on all of the systems with which you need to work. Using one .vimrc file enables you to include it as part of a centralized set of dotfiles that you can keep under version control .

However, if on a particular machine there's a special case which means you need to load some Vim directives for that machine, you can achieve this by way of a local Vim file kept in .vimrc.local , only on one particular machine, and detecting its existence before attempting to load it in your master .vimrc file with the following stanza:

if filereadable(glob("~/.vimrc.local")) 
    source ~/.vimrc.local
endif

As an example, on one of the nameservers that I manage, I wanted to make sure that the correct filetype was loaded when editing zone files ending in .nz or .au for New Zealand and Australian domains. The following line in .vimrc.local did the trick:

autocmd BufNewFile,BufRead *.au,*.nz set filetype=bindzone

If the .vimrc.local file doesn't exist on any particular machine, Vim will simply not attempt to load it on startup.

Besides machine-specific code, this kind of setup may be advisable if you keep secret or potentially sensitive information in your .vimrc file that you wouldn't want published to a public version control tracker like GitHub, such as API keys, usernames, machine hostnames, or network paths.

[Oct 31, 2017] Vim eval feature by Tom Ryder

Jul 19, 2012 | sanctum.geek.nz

Using your .vimrc file on many machines with different versions and feature sets for Vim is generally not too much of a problem if you apply a little care in making a gracefully degrading .vimrc . In most cases, using the output of vim --version and checking the help files will tell you what features to check in order to determine which parts of your .vimrc configuration to load, and which to ignore.

There's one particular feature that's less obvious, though, and that's eval . Vim's help describes it like this in :help +eval :

N  *+eval*      expression evaluation |eval.txt|

The eval.txt document, in turn, describes the syntax for various features fundamental to Vimscript, including variables, functions, lists, and dictionaries.

All this makes eval perhaps the most central feature of Vim. Without it, Vim doesn't have much of its programmable nature, and remains not much more than classic vi . If your particular build of Vim doesn't include it, then Vimscript essentially does not work as a programming language, and elementary calls like function and let will throw errors:

E319: Sorry, the command is not available in this version: function
E319: Sorry, the command is not available in this version: let

If you're getting this kind of error, you're probably using a very stripped-down version of Vim that doesn't include eval . If you just want to prevent the error by ignoring a block of code if the feature is unavailable, you can do this with has() :

if has("eval")
    ...
endif

Vim will still be perfectly functional as a vi -style editor without +eval , but if you're going to need any Vimscript at all, you should recompile Vim with a --with-features value for the ./configure line that does include it, such as normal , big , or huge , or install a more fully-featured packaged version. For example, on Debian-like systems, the vim-tiny package that is included in the netinst system does not include eval , but the vim and vim-runtime packages do.

Inspecting Vim's source, in particular the ex_docmd.c file, gives some indication of how fundamental this feature is, applying the C function ex_ni which simply prints the "not available" error shown above to a large number of control structures and statements if the FEAT_EVAL constant is not defined:

#ifndef FEAT_EVAL
# define ex_scriptnames     ex_ni
# define ex_finish      ex_ni
# define ex_echo        ex_ni
# define ex_echohl      ex_ni
# define ex_execute     ex_ni
# define ex_call        ex_ni
# define ex_if          ex_ni
# define ex_endif       ex_ni
# define ex_else        ex_ni
# define ex_while       ex_ni
# define ex_continue        ex_ni
# define ex_break       ex_ni
# define ex_endwhile        ex_ni
# define ex_throw       ex_ni
# define ex_try         ex_ni
# define ex_catch       ex_ni
# define ex_finally     ex_ni
# define ex_endtry      ex_ni
# define ex_endfunction     ex_ni
# define ex_let         ex_ni
# define ex_unlet       ex_ni
# define ex_lockvar     ex_ni
# define ex_unlockvar       ex_ni
# define ex_function        ex_ni
# define ex_delfunction     ex_ni
# define ex_return      ex_ni
# define ex_oldfiles        ex_ni

[Oct 31, 2017] Vim misconceptions by Tom Ryder

Jul 19, 2012 | sanctum.geek.nz

Vim isn't the best tool for every task, and there's no reason you shouldn't stick to your GUI IDE if you know it like the back of your hand and are highly productive in it. The very basic best practices for text editing in general apply just as well to more familiar editing interfaces as they do to Vim, so nobody should be telling you that Vim is right for everyone and everything and that you're wrong not to use it.

However, because Vim and vi -like editors in general have a lot of trouble shaking off the connotations of their serverside, terminal-only, mouseless past, there are a few persistent objections to even trying Vim that seem to keep cropping up. If you're someone curious about Vim but you heard it was useless for any of the following reasons, or if you're an experienced user looking to convince a hesitant neophyte to try Vim, the following list might clear a few things up.

Vim takes too long to learn

If you want analogues to all of the features in your IDE, that would likely take some time, just as it would in any other new editor. However, if all you need to start is to be able to enter text, move around, and load and save files, you just need to know:

To do pretty much everything Windows Notepad would let you do, on top of that you'd only need to learn:

From that point, you only get faster as you learn how to do new things. So saying that Vim takes weeks to learn is a bit disingenuous when the essentials can easily be mastered with a few minutes' practice.

Granted, the arrow keys are a bit of an anti-pattern , but you can worry about that later.

Vim has no GUI

Vim has a GUI version called Gvim for both Windows and Unix. For Mac OS X, the MacVim port is preferred. For experienced users the GUI's only real advantage over the terminal version is a wider color palette, but it has a toolbar and other GUI elements which some new users may find useful.

Vim doesn't have spell checking

Vim allows spell checking with system dictionaries, using :set spell and :set spelllang . Misspelt and unknown words are highlighted appropriately.

Vim doesn't have syntax highlighting

Vim has support for syntax highlighting that can be turned on with :syntax enable , for a very wide variety of programming languages, markup languages, and configuration file syntaxes.

Vim only allows eight colours

This is a limitation of terminal emulators rather than of Vim itself, but most modern GUI terminal emulators allow 256 colours anyway with a little extra setup. The GUI version, Gvim, has full color support with the familiar rrggbb color definitions.

Vim doesn't have class/function folding

Vim does in fact have support for folding , based on both code structure and manually defined boundaries. See :help folding for details.

Vim doesn't have autocompletion

Vim allows basic completion using words already in the current buffer, and also more advanced omnicompletion using language dictionaries for constants, variables, classes, and functions.

Vim doesn't have a file browser

Vim has had the Netrw plugin bundled for some time, which provides a pretty capable filesystem browser.

Vim can't do network editing

Again, the bundled Netrw plugin handles this. Editing files over FTP and SCP links is pretty transparent. You can open a file on a remote server by entering the following, which will prompt for your username and password:

:e ftp://ftp.example.com/index.html

When you're done editing, you just enter :w to save the file, and it's automatically uploaded for you. You can record your FTP credentials in a .netrc file to save having to type in usernames and passwords all the time. URIs with scp:// work the same way; with a good public key infrastructure set up, you can use Vim quite freely as a network-transparent editor.

Vim doesn't have tabs or windows

The model Vim uses for tabs and windows is rather different from most GUI editors, but both are supported and have been for some time.

Vim has too many modes

It has three major modes: normal mode, insert mode, and command mode. There's a fourth that's Vim-specific, called visual mode, for selecting text.

Most editors are modal in at least some respect; when you bring up a dialog box, or enter a prefix key to another command, you're effectively changing modes. The only real difference is that context shifts in Vim are at first less obvious; the screen doesn't look too different between normal, insert, and command mode.

The showmode option helps to distinguish between insert and normal mode, a common frustration for beginners. This gets easier when you get into the habit of staying out of insert mode when not actually entering text.

Vim doesn't work with the mouse

Vim works fine with the mouse , in both Gvim and xterm -like terminal emulators, if you really want it. You can change the position of the cursor, scroll through the document, and select text as normal. Setting the below generally does the trick:

:set mouse=a

However, even a little experience in Vim may show you that you don't need the mouse as much as you think. Careful use of the keyboard allows much more speed and precision, and it's quite easy to run a complex editing session without even moving from the keyboard's "home row", let alone all the way over to the mouse.

Vim doesn't do Unicode

Vim supports Unicode encodings with the encoding option. It's likely you'll only need to put the below in your .vimrc file and then never really think about encoding in your editor again:

:set encoding=utf-8
Vim isn't being developed or maintained

The original author of Vim, and its current maintainer and release manager, is Bram Moolenaar . At the time of writing, he is working for Google, and is paid to spend some of his time developing Vim. The development mailing list for Vim is very active, and patches are submitted and applied to the publically accessible Mercurial repository on a regular basis. Vim is not a dead project.

Vim is closed source

Vim isn't proprietary or closed source, and never has been. It uses its own GPL-compatible license called the Vim license .

The original vi used to be proprietary because Bill Joy based the code on the classic UNIX text editor ed , but its source code has now been released under a BSD-style license.

[Oct 31, 2017] Vim annoyances by Tom Ryder

Notable quotes:
"... Several of these fixes were inspired by Steve Losh's .vimrc file . Thanks also to commenters Alpha Chen and Rob Hoelz for suggestions. ..."
Aug 02, 2012 | sanctum.geek.nz

Like any highly interactive application, Vim has a few annoyances even for experienced users. Most of these consist of the editor doing something unexpected, particularly with motions or the behavior of regular expressions and registers. This is often due to vi and Vim being such venerable editors; their defaults sometimes make less sense decades after their creation.

Fortunately, Vim being the configurable editor that it is, many of the more common annoyances can be easily worked around. Bear in mind that not all of these are necessarily problems; if you actually prefer the way something behaves, you should stick with it.

Cursor jumps around while joining lines

If you want to keep the cursor in place when you join lines with J , you can do this, dropping a mark before the operation to which you return afterwards:

nnoremap J mzJ`z
Jumping lands on top or bottom of screen

If you'd like to center the window automatically around the cursor after jumping to a location with motions like n (next search pattern occurrence) or } (end of next paragraph), you can arrange that by remapping to add a zz after the motion:

nnoremap n nzz
nnoremap } }zz

If you don't need the jump to land you in the exact middle of the screen, but just don't want it to land right at the edge, you could also use scrolloff :

set scrolloff=10

Note that this also starts scrolling the window with single-line movements like j and k at this boundary, too, which you may not want.

Skipping lines when wrap is set

By default, the j and k keys don't move by row ; they move by line . This means that if you have the wrap option set, you might skip across several rows to reach the same point in an adjacent line.

This can be frustrating if you prefer the more intuitive behavior of moving up to the character immediately above the current one. If you don't like this behavior, you can fix it by mapping j to gj , and k to gk , which moves by rows rather than lines:

nnoremap j gj
nnoremap k gk

If you think you might need the default behavior at some point, you might want to include reverse mappings so you can move linewise with gj and gk :

nnoremap gj j
nnoremap gk k
Wrapping breaks words

By default, setting wrap displays lines by breaking words if necessary. You can force it to preserve words instead by only breaking at certain characters:

set linebreak

You can define the characters at which Vim should be allowed to break lines with the breakat option. By default this includes spaces and tabs.

Backup files are a nuisance

If you're developing with a version control system, you might find the in-place backups Vim keeps for saved files with the ~ suffix more annoying than useful. You can turn them off completely with nobackup :

set nobackup

Alternatively, you can set a single directory for them to keep them out of the way with backupdir :

set backupdir=~/.vim/backup
Swap files are a nuisance

Swap files can be similarly annoying, and unnecessary on systems with a lot of memory. If you don't need them, you can turn them off completely:

set noswapfile

If you do find the swap files useful but want to prevent them cluttering your current directory, you can set a directory for them with directory :

set directory=~/.vim/swap
Accidentally hitting unwanted keys in normal mode

Some of the keys in normal mode bring up functions that aren't terribly useful to a lot of people, and tend to accidentally get hit when Caps Lock is on, or when aiming for another key. Common nuisance keys are:

The simplest way to deal with these is to remap them to <nop> so that they don't do anything:

nnoremap <F1> <nop>
nnoremap Q <nop>
nnoremap K <nop>
Startup message is irritating

If you don't like the startup message that appears when you open Vim without a filename, you can remove it by adding the I flag to shortmess :

set shortmess+=I
Can't backspace past start of operation

If you're in insert mode, by default you can't use backspace to delete text past the start of the insert operation; that is, you can't backspace over where you first pressed insert. This is old vi behavior, and if you don't like it, you can make backspace work everywhere instead:

set backspace=indent,eol,start
Flashing screen is annoying

If you don't require the error feedback, you can turn off the flashing screen for the "visual bell":

set visualbell t_vb=
Don't know what mode I'm in

If you lose track of the current mode, you can get a convenient --INSERT-- indicator at the bottom of the screen with:

set showmode

If you're having this problem a lot, however, you might want to take stock of how much time you're spending in insert mode when you're not actively typing; it's good Vim practice to stay out of it otherwise, even when you stop to think.

Keep making typos of common commands

If you're fat-fingering :wq and similar commands a lot due to a sticky shift key, take a look at the Vim command typos fix. Also, don't forget about ZZ and ZQ as quicker alternatives to :wq and :q! .

Don't want case sensitive patterns

If you don't care for case-sensitive searches and substitutions, you can turn it off completely:

set ignorecase

You might find the slightly cleverer behavior of smartcase is better, though. This option only applies case sensitivity if at least one of the letters in the pattern is uppercase; otherwise, case is ignored.

set smartcase
Doesn't replace all occurrences

The default behavior for the substitute operation, :s/pattern/replacement/ , is to replace only the first occurrence of the pattern. To make it replace all occurrences on the appropriate lines, you add the g suffix. If you find that you never need to substitute for only the first occurrence of a pattern in a line, you can add that flag to the patterns by default:

set gdefault

If you do happen to need to replace only the first occurrence one day, you can get the default behavior back by adding the g suffix to your pattern; its meaning is reversed by this option.

Can't move into blank space in visual block mode

If you need to define a block in visual block mode with bounds outside the actual text (that is, past the end of lines), you can allow this with:

set virtualedit=block

This will let you move around the screen freely while in visual block mode to define your selections. As an example, this can make selecting the contents of the last column in a formatted table much easier.

Filename completion on command line is confusing

If you're used to the behavior of shell autocomplete functions for completing filenames, you can emulate it in Vim's command mode:

set wildmode=longest,list

With this set, the first Tab press (or whatever your wildchar is set to) will expand a filename or command in command mode to the longest common string it can, and a second press will display a list of all possible completions above the command line.

Yanking lines is inconsistent

D deletes from the cursor to the end of the line; C changes from the cursor to the end of the line. For some reason, however, Y yanks the entire line, both before and after the cursor. If this inconsistency bothers you, you can fix it with a remapping:

nnoremap Y y$
New splits appear in unintuitive places

If your language of choice is read from left to right, you may find it annoying that by default Vim places new vertical splits to the left of the current pane, and horizontal splits above the current pane. You can fix both:

set splitbelow
set splitright
Caps Lock sends Vim crazy

Caps Lock in normal mode makes Vim go haywire. This isn't really Vim's fault; Caps Lock is generally a pretty useless key. It's often useful for Vim users to remap it , so that it sends the same signal as a more useful key; Control and Escape are common choices. You might even find this reduces strain on your hands.

Several of these fixes were inspired by Steve Losh's .vimrc file . Thanks also to commenters Alpha Chen and Rob Hoelz for suggestions.

[Oct 31, 2017] Shell from vi by Tom Ryder

Feb 18, 2017 | sanctum.geek.nz

A good sign of a philosophically sound interactive Unix tool is the facilities it offers for interacting with the filesystem and the shell: specifically, how easily can you run file operations and/or shell commands with reference to data within the tool? The more straightforward this is, the more likely the tool will fit neatly into a terminal-driven Unix workflow.

If all else fails, you could always suspend the task with Ctrl+Z to drop to a shell, but it's helpful if the tool shows more deference to the shell than that; it means you can use and (even more importantly) write tools to manipulate the data in the program in whatever languages you choose, rather than being forced to use any kind of heretical internal scripting language, or worse, an over-engineered API.

vi is a good example of a tool that interacts openly and easily with the Unix shell, allowing you to pass open buffers as streams of text transparently to classic filter and text processing tools. In the case of Vim, it's particularly useful to get to know these, because in many cases they allow you to avoid painful Vimscript, and to do things your way, without having to learn an ad-hoc language or to rely on plugins. This was touched on briefly in the "Editing" article of the Unix as IDE series.

Choosing your shell

By default, vi will use the value of your SHELL environment variable as the shell in which your commands will be run. In most cases, this is probably what you want, but it might pay to check before you start:

:set shell?

If you're using Bash, and this prints /bin/bash , you're good to go, and you'll be able to use Bash-specific features or builtins such as [[ comfortably in your command lines if you wish.

Running commands

You can run a shell command from vi with the ! ex command. This is inherited from the same behaviour in ed . A good example would be to read a manual page in the same terminal window without exiting or suspending vi :

:!man grep

Or to build your project:

:!make

You'll find that exclamation point prefix ! shows up in the context of running external commands pretty consistently in vi .

You will probably need to press Enter afterwards to return to vi . This is to allow you to read any output remaining on your screen.

Of course, that's not the only way to do it; you may prefer to drop to a forked shell with :sh , or suspend vi with ^Z to get back to the original shell, resuming it later with fg .

You can refer to the current buffer's filename in the command with % , but be aware that this may cause escaping problems for files with special characters in their names:

:!gcc % -o foo

If you want a literal % , you will need to escape it with a backslash:

:!grep \% .vimrc

The same applies for the # character, for the alternate buffer .

:!gcc # -o bar
:!grep \# .vimrc

And for the ! character, which expands to the previous command:

:!echo !
:!echo \!

You can try to work around special characters for these expansions by single-quoting them:

:!gcc '%' -o foo
:!gcc '#' -o bar

But that's still imperfect for files with apostrophes in their names. In Vim (but not vi ) you can do this:

:exe "!gcc " . shellescape(expand("%")) . " -o foo"

The Vim help for this is at :help :! .

Reading the output of commands into a buffer

Also inherited from ed is reading the output of commands into a buffer, which is done by giving a command starting with ! as the argument to :r :

:r !grep vim .vimrc

This will insert the output of the command after the current line position in the buffer; it works in the same way as reading in a file directly.

You can add a line number prefix to :r to place the output after that line number:

:5r !grep vim .vimrc

To put the output at the very start of the file, a line number of 0 works:

:0r !grep vim .vimrc

And for the very end of the file, you'd use $ :

:$r !grep vim .vimrc

Note that redirections work fine, too, if you want to prevent stderr from being written to your buffer in the case of errors:

:$r !grep vim .vimrc 2>>vim_errorlog
Writing buffer text into a command

To run a command with standard input coming from text in your buffer, but without deleting it or writing the output back into your buffer, you can provide a ! command as an argument to :w . Again, this behaviour is inherited from ed .

By default, the whole buffer is written to the command; you might initially expect that only the current line would be written, but this makes sense if you consider the usual behaviour of w when writing directly to a file.

Given a file with a first column full of numbers:

304 Donald Trump
227 Hillary Clinton
3   Colin Powell
1   Spotted Eagle
1   Ron Paul
1   John Kasich
1   Bernie Sanders

We could calculate and view (but not save) the sum of the first column with awk(1) , to see the expected value of 538 printed to the terminal:

:w !awk '{sum+=$1}END{print sum}'

We could limit the operation to the faithless electoral votes by specifying a line range:

:3,$w !awk '{sum+=$1}END{print sum}'

You can also give a range of just . , if you only want to write out the current line.

In Vim, if you're using visual mode, pressing : while you have some text selected will automatically add the '<,'> range marks for you, and you can write out the rest of the command:

:'<,'>w !grep Bernie

Note that this writes every line of your selection to the command, not merely the characters you have selected. It's more intuitive to use visual line mode (Shift+V) if you take this approach.

Filtering text

If you want to replace text in your buffer by filtering it through a command, you can do this by providing a range to the ! command:

:1,2!tr '[:lower:]' '[:upper:]'

This example would capitalise the letters in the first two lines of the buffer, passing them as input to the command and replacing them with the command's output.

Note that the number of lines passed as input need not match the number of lines of output. The length of the buffer can change. Note also that by default any stderr is included; you may want to redirect that away.

You can specify the entire file for such a filter with % :

:%!tr '[:lower:]' '[:upper:]'

As before, the current line must be explicitly specified with . if you want to use only that as input, otherwise you'll just be running the command with no buffer interaction at all, per the first heading of this article:

:.!tr '[:lower:]' '[:upper:]'

You can also use ! as a motion rather than an ex command on a range of lines, by pressing ! in normal mode and then a motion ( w , 3w , } , etc) to select all the lines you want to pass through the filter. Doubling it ( !! ) filters the current line, in a similar way to the yy and dd shortcuts, and you can provide a numeric prefix (e.g. 3!! ) to specify a number of lines from the current line.

This is an example of a general approach that will work with any POSIX-compliant version of vi . In Vim, you have the gU command available to coerce text to uppercase, but this is not available in vanilla vi ; the best you have is the tilde command ~ to toggle the case of the character under the cursor. tr(1) , however, is specified by POSIX–including the locale-aware transformation–so you are much more likely to find it works on any modern Unix system.

If you end up needing such a command during editing a lot, you could make a generic command for your private bindir , say named upp for uppercase, that forces all of its standard input to uppercase:

#!/bin/sh
tr '[:lower:]' '[:upper:]'

Once saved somewhere in $PATH and made executable, this would allow you simply to write the following to apply the filter to the entire buffer:

:%!upp

The main takeaway from this is that the scripts you use with your editor don't have to be in shell. You might prefer Awk :

#!/usr/bin/awk -f
{ print toupper($0) }

Or Perl :

#!/usr/bin/env perl
print uc while <>;

Or Python, or Ruby, or Rust , or

Incidentally, this "filtering" feature is where vi 's heritage from ed ends as far as external commands are concerned. In POSIX ed , there isn't a way to filter buffer text through a command in one hit. It's not too hard to emulate it with a temporary file, though, using all the syntax learned above:

*1,2w !upp > tmp
*1,2d
*0r tmp
*!rm tmp

[Oct 31, 2017] Vim search highlighting by Tom Ryder

Jan 21, 201 | sanctum.geek.nz

Being able to search by regular expression is a pretty fundamental thing in a text editor. Vim takes it to the next level by making entering a search into a motion all on its own, and even a few weeks' Vim experience and you'll probably catch yourself using the search to navigate your buffers.

One of the things I most commonly see recommended in threads and discussions about useful Vim features includes turning on two kinds of search highlighting: first, highlighting the search result on which you'll land as you type it, and secondly, once you've pressed Enter to run your search, highlighting all of the matches. You turn these on like this:

:set incsearch
:set hlsearch

This ends up being great for editing code in particular, because if you search for variable or function names, you can see at a glance where they're declared, defined, or used in your code. Couple that with the quick forward and backward search that you can do with the * and # keys, and you have a very convenient way to flick through successive uses of an identifier.

The only snag, really, is that it doesn't turn itself off, and it gets visually distracting when you've moved on from whatever task prompted the search, and because you might search to move around, you don't always actually want the highlighting to stay there. Text editors following a Windows model would probably clear away the highlighting as soon as you close the search box, or insert some text. This isn't the case with Vim, which can be good or bad, but most people I've spoken to about this feature seem to find it annoying.

Bram Moolenar, the author of Vim, addressed this very topic in a Google Tech Talk he gave about effective text editing . You can turn off the highlighting temporarily by typing:

:nohlsearch

This is different from :set nohlsearch in that it doesn't permanently disable the highlighting. It'll turn it on next time you search. I find this is kind of a pain to type, so I alias it to Ctrl+L in my .vimrc file, so that in addition to its default behaviour of clearing the screen it clears the search highlighting as well:

nnoremap <C-l> :nohlsearch<CR><C-l>

Additionally, I like to set leader keys to quickly turn the highlighting option on and off completely if for some particular project it's just thoroughly unhelpful. In this example, typing \i and \h will toggle the incsearch and hlsearch settings on and off, respectively. I'm assuming you're using the backslash key as your <leader> here.

nnoremap <leader>i :set incsearch!<CR>
nnoremap <leader>h :set hlsearch!<CR>

Finally, I find that while I'm in insert mode, I usually don't want to see the highlighting, so I define events to turn the highlighting off temporarily in the current buffer while I'm inserting text:

autocmd InsertEnter * :setlocal nohlsearch
autocmd InsertLeave * :setlocal hlsearch

I find these shortcuts make the search highlighting behaviour much less annoying. Interestingly, according to Vim's help, you can't simply add an event hook to run :nohlsearch when you enter Insert mode (from :help nohlsearch ):

This command doesn't work in an autocommand, because the highlighting state is saved and restored when executing autocommands. Same thing for when invoking a user function.

You can work around this by setting the search pattern to empty instead, as suggested by this Stack Overflow answer , but I don't really like doing that because I often like to recurse through more search results with n and N after leaving insert mode.

Jan 22, 2012 | sanctum.geek.nz

Posted on If you've moved to Vim from an editor like Notepad++ or TextMate, you'll be used to working with the idea of tabs in a text editor in a certain way. Specifically, a tab represents an open file; while the tab's there, you've got an open file, as soon as you close it, it goes away. This one-to-one correspondence is pretty straightforward and is analogous to using tabs in a web browser; while the page is open, there's a tab there, and you have one page per tab, and one tab per page.

Vim has a system for tabs as well, but it works in a completely different way from how text editors and browsers do. Beginners with Vim are often frustrated by this because the model for tabs is used so consistently in pretty much every other program they're accustomed to, and they might end up spending a lot of fruitless time trying to force Vim to follow the same model through its configuration.

I think a good way to understand the differences in concept and usage between Vim's three levels of view abstraction -- buffers windows , and tabs -- is to learn how to use each from the ground up. So let's start with buffers.

Buffers

A buffer in Vim is probably best thought of for most users as an open instance of a file , that may not necessarily be visible on the current screen. There's probably a more accurate technical definition as a buffer need not actually correspond to a file on your disk, but it'll work for our purposes.

When you open a single file in Vim, that file gets put into a buffer, and it's the only buffer there on startup. If this buffer is unmodified (or if you're using hidden ), and you open another file with :edit , that buffer goes into the background and you start working with the new file. The previous buffer only goes away when you explicitly delete it with a call to :quit or :bdelete , and even then it's still recoverable unless you do :bwipe .

By default, a buffer can only be in the background like this if it's unmodified. You can remove this restriction if you like with the :set hidden option.

You can get a quick list of the buffers open in a Vim session with :ls . This all means that when most people think of tabs in more familiar text editors, the idea of a buffer in Vim is actually closest to what they're thinking.

Windows

A window in Vim is a viewport onto a single buffer . When you open a new window with :split or :vsplit , you can include a filename in the call. This opens the file in a new buffer, and then opens a new window as a view onto it. A buffer can be viewed in multiple windows within a single Vim session; you could have a hundred windows editing the same buffer if you wanted to.

Windows in Vim

Vim Session with multiple windows open, both horizontally and vertically. Tabs

Finally, a tab in Vim is a collection of one or more windows . The best way to think of tabs, therefore, is as enabling you to group windows usefully. For example, if you were working on code for both a client program and a server program, you could have the files for the client program open in the first tab, perhaps in three or four windows, and the files for the server program open in another, which could be, say, seven windows. You can then flick back and forth between the tabs using :tabn and :tabp .

Tab usage in Vim

Two tabs open in Vim, each with multiple windows. Move between two tabs with :tabn and :tabp.

This model of buffers, windows, and tabs is quite a bit more intricate than in other editors, and the terms are sometimes confusing. However, if you know a bit about how they're supposed to work, you get a great deal more control over the layout of your editing sessions as a result. Personally, I find I rarely need tabs as with a monitor of sufficient size it suffices to keep two or three windows open at a time when working on sets of files, but on the odd occasion I do need tabs, I do find them tremendously useful.

Thanks to Hacker News users anonymous and m0shen for pointing out potential confusion with the :set hidden option and the :bdelete command.

[Oct 31, 2017] Vim command window by Tom Ryder

Feb 05, 2012 | sanctum.geek.nz

The command line in Vim for ex commands can be edited with a few of the GNU Readline key combinations that may be familiar to Bash or Emacs users, so it's reasonably easy to edit it, for example to type in complex search patterns and replacements.

However, if you want the full facility of Vim editing for your commands, it can be helpful to use Vim's command line window, which will allow you to enter commands and edit previous ones with the usual normal and insert mode.

You can open the command line window from normal mode in one of four ways:

Note that this doesn't work while you're recording macros, since pressing q stops the recording.

The window is always immediately above the status bar, and its height can be set via the cmdwinheight option.

Command line window

Once the command line window is opened with q: , you can browse through it and press Enter on any line to issue the same command again. You can also edit it beforehand, perhaps to fix a mistyped command. The window will close when this is done, but you can close it with Ctrl+W, C the same as any other window if you change your mind.

Vim command line window

Note that you can't move to another window while this one is open, nor can you load another buffer into it.

Search window

Similar to the above, if you open the command window with q/ or q? , it shows a history of your searches, and pressing enter on any line will issue the same again, in the appropriate direction.

[Oct 31, 2017] Vim anti-patterns by Tom Ryder

Feb 07, 2012 | sanctum.geek.nz

The benefits of getting to grips with Vim are immense in terms of editing speed and maintaining your "flow" when you're on a roll, whether writing code, poetry, or prose, but because the learning curve is so steep for a text editor, it's very easy to retain habits from your time learning the editor that stick with you well into mastery. Because Vim makes you so fast and fluent, it's especially hard to root these out because you might not even notice them, but it's worth it. Here I'll list some of the more common ones. Moving one line at a time

If you have to move more than a couple of lines, moving one line at a time by holding down j or k is inefficient. There are many more ways to move vertically in Vim. I find that the two most useful are moving by paragraph and by screenful, but this depends on how far and how precisely you have to move.

If you happen to know precisely where you want to go, navigating by searching is the way to go, searching forward with / and backward with ? .

It's always useful to jump back to where you were, as well, which is easily enough done with two backticks, or gi to go to the last place you inserted text. If you like, you can even go back and forth through your entire change list of positions with g; and g, .

Moving one character at a time

Similarly, moving one character at a time with h and l is often a waste when you have t and f :

Moving wordwise with w , W , b , B , e , and E is better, too. Again, searching to navigate is good here, and don't forget you can yank , delete or change forward or backward to a search result:

y/search<Enter>
y?search<Enter>
d/search<Enter>
d?search<Enter>
c/search<Enter>
c?search<Enter>
Searching for the word under the cursor

Don't bother typing it, or yanking/pasting it; just use * or # . It's dizzying how much faster this feels when you use it enough for it to become automatic.

Deleting, then inserting

Deleting text with intent to replace it by entering insert mode immediately afterward isn't necessary:

d2wi

It's quicker and tidier to use c for change:

c2w

This has the added benefit of making the entire operation repeatable with the . command.

Using the arrow keys

Vim lets you use the arrow keys to move around in both insert and normal mode, but once you're used to using hjkl to navigate, moving to the arrow keys to move around in text feels clumsy; you should be able to spend the vast majority of a Vim session with your hands firmly centered around home row . Similarly, while the Home and End keys work the same way they do in most editors, there's no particular reason to use them when functional equivalents are closer to home in ^ and $ .

So wean yourself off the arrow keys, by the simple expedient of disabling them entirely, at least temporarily:

noremap <Up> <nop>
noremap <Down> <nop>
noremap <Left> <nop>
noremap <Right> <nop>

The benefits of sticking to home row aren't simply in speed; it feels nicer to be able to rest your wrists in front of the keyboard and not have to move them too far, and for some people it has even helped prevent repetitive strain injury .

Moving in insert mode

There's an additional benefit to the above in that it will ease you into thinking less about insert mode as a mode in which you move around; that's what normal mode is for. You should, in general, spend as little time in insert mode as possible. When you want to move, you'll get in the habit of leaving insert mode, and moving around far more efficiently in normal mode instead. This distinction also helps to keep your insert operations more atomic , and hence more useful to repeat.

Moving to Escape

The Escape key on modern keyboards is a lot further from home row than it was on Bill Joy's keyboard back when he designed vi. Hitting Escape is usually unnecessary; Ctrl+[ is a lot closer, and more comfortable. It doesn't take long using this combination instead to make reaching for Escape as you did when you were a newbie feel very awkward. You might also consider mapping the otherwise pretty useless Caps Lock key to be another Escape key in your operating system, or even mapping uncommon key combinations like jj to Escape. I feel this is a bit drastic, but it works well for a lot of people:

inoremap jj <Esc>
Moving to the start or end of the line, then inserting

Just use I and A . Again, these make the action repeatable for other lines which might need the same operation.

Entering insert mode, then opening a new line

Just use o and O to open a new line below and above respectively, and enter insert mode on it at the same time.

Entering insert mode to delete text

This is a pretty obvious contradiction. Instead, delete the text by moving to it and using d with an appropriate motion or text object. Again, this is repeatable, and means you're not holding down Backspace. In general, if you're holding down a key in Vim, there's probably a faster way.

Repeating commands or searches

Just type @: for commands or n / N for searches; Vim doesn't forget what your last search was as soon as you stop flicking through results. If it wasn't your most recent command or search but it's definitely in your history, just type q: or q/ , find it in the list , and hit Enter.

Repeating substitutions

Just type & to repeat the last substitution on the current line. You can repeat it on all lines by typing g& .

Repeating macro calls

Just type @@ .

These are really only just a few of the common traps to avoid to increase your speed and general efficiency with the editor without requiring plugins or substantial remappings. Check out the Vim Tips wiki for some other really helpful examples.

[Oct 31, 2017] Debugging Vim setup by Tom Ryder

Oct 31, 2017 | sanctum.geek.nz

While Vim's core is very stable, problems can come about when extending the editor with plugins, particularly if there are a high number of them or if they're buggy or not very well written. While Vim offers a number of ways to keep scripts' behaviours isolated from one another, it may happen that you find Vim behaving in an unexpected way that you can't quite pin down. There are a few very good approaches to figuring this out. List your scripts

First of all, it helps to get a handle on what exactly you've got loaded during your Vim sessions. You can do this with the :scriptnames command:

:scriptnames
1: /usr/share/vim/vimrc
2: /usr/share/vim/vim73/debian.vim
3: ~/.vimrc
4: ~/.dotfiles/vim/autoload/pathogen.vim
...

This list appears in the order in which the files were loaded, which might give you a starting point for figuring out where the problem lies.

Update your plugins

Check the documentation, release logs, known problems, and in particular the website of your chosen plugins to see if there are any recent updates to them. If they're hosted on GitHub, pull down the most recent versions.

Start with no plugins

You can start Vim with no plugins, in a pristine state that doesn't source any vimrc files from your system or home directories, to figure out if the behaviour you're observing still occurs with no plugins at all installed. This is done by calling Vim with the -u and -U options, which normally specify the path to a custom location for vimrc and gvimrc files respectively, with the special parameter of NONE :

$ vim -u NONE -U NONE

Vim will open and you'll see the usual blue tildes for opening a line and Vim's opening splash screen, having completely ignored your laborious setup.

This done, you can source plugins individually until you notice the problem starts happening, by a process of elimination:

:so plugin/fugitive.vim
:so plugin/unimpaired.vim
:so plugin/badplugin.vim
Profile startup time

If Vim was compiled with the +startuptime feature, you can also pass the --startuptime flag to it with a filename argument, and it will save a verbose log of its startup procedure to that file for you to inspect:

$ vim +q --startuptime startuptime.txt
$ vim startuptime.txt

There's way more information in here than you're ever likely to need, but in the case of a buggy setup or unacceptably slow startup time, it's very useful for diagnosing the bottleneck in your setup.

Best code editors for Linux

Brief: Looking for best programming editors in Linux? Here's a list of best code editors for Linux. The best part is that all of them are open source code editors.

If you ask the old school Linux users, their answer would be Vi, Vim, Emacs, Nano etc. But I am not talking about them. I am going to talk about new age, cutting edge, great looking, sleek and yet powerful, feature-rich best open source code editors for Linux that would enhance your programming experience.

Best modern Open Source editors for Linux

I use Ubuntu as my main desktop and hence I have provided installation instructions for Ubuntu based distributions. But this doesn't make this list as best code editors for Ubuntu because the list is apt for any Linux distribution. Just to add, the list is not in any particular priority order.

1. Brackets

Brackets is one of the best open source code editors

Brackets is an open source code editor from Adobe . Brackets focuses exclusively on the needs of web designers with built-in support for HTML, CSS and JavaScript. It is lightweight and yet powerful. It provides you with inline editing and live preview. There are plenty of plugins available to further enhance your experience with Brackets.

Some of the main features of Brackets code editor are:

You can get the source code as well as binaries for Linux, OS X and Windows on its website.

Get Brackets

2. Atom

Atom is considered to be an excellent code editor for Linux

Atom is another modern and sleek looking open source editor for programmers. Atom is developed by Github and promoted as a "hackable text editor for the 21st century". The looks of Atom resembles a lot like Sublime Text editor, a hugely popular but closed source text editors among programmers.

Some of the main features of Atom code editor are:

Atom has recently released .deb and .rpm packages so that one can easily install Atom in Debian and Fedora based Linux distributions. Of course, its source code is available as well.

Get Atom

3. Light Table

Light Table is the next generation open source code editor for Linux

Flaunted as "the next generation code editor", Light Table is another modern looking, underrated yet feature-rich open source code editor which is more of an IDE than a mere text editor.

There are numerous extensions available to enhance its capabilities. Inline evaluation is what you would love in it. You have to use it to believe how useful Light Table actually is.

Some of the main features of Light Table are:

If you are using Ubuntu-based Linux distribution, then installing Light Table is easier for you. However, officially, Light Table doesn't provide any packages. You have to build it yourself.

Get Light Table

4. Visual Studio Code

Microsoft Visual Studio Code has been deemed as the best code editor for web development

Visual Studio Code is a popular code editor from Microsoft. Now don't push the panic button just yet. Visual Studio Code is completely open source.

In fact, Visual Studio Code was among the first few 'peace offering' from Microsoft to Linux and Open Source world. Microsoft has open sourced a number of its tools after that. Of course, that doesn't include Microsoft Office.

Visual Studio Code is an excellent code editor, especially for web development. It is lightweight as well. Some of the other main features are:

You can download packages for Ubuntu and Fedora from its website:

Get Visual Studio Code

What's your pick?

No, we are not limited to just four code editors in Linux. The list was about modern editors for programmers. Of course, you have plenty of other options such as Notepad++ alternative Notepadqq or SciTE and many more. So, among these four, which one is your favorite code editor for Linux? 47 comments

[Aug 01, 2014] Comparison Linux Text Editors

Slashdot

jrepin writes: Mayank Sharma of Linux Voices tests and compares five text editors for Linux, none of which are named Emacs or Vim. The contenders are Gedit, Kate, Sublime Text, UltraEdit, and jEdit. Why use a fancy text editor? Sharma says, "They can highlight syntax and auto-indent code just as effortlessly as they can spellcheck documents. You can use them to record macros and manage code snippets just as easily as you can copy/paste plain text. Some simple text editors even exceed their design goals thanks to plugins that infuse them with capabilities to rival text-centric apps from other genres. They can take on the duties of a source code editor and even an Integrated Development Environment."

I used Xedit as well, as well as EDIT and EDGAR before it. Having learned programming on the IBM Mainframes, what else would I have used? I later picked up an editor with no name for DOS, just E.EXE. It was one of IBM's internal company programming editors never released to the public.

In 1993 I lost my copy of E, and I was unable to obtain a new copy. It was better than Xedit, and still used REXX as a scripting language.

In 1995, I picked up a copy of UltraEdit for Windows 95. It didn't do everything that my old E.EXE did, but I was pretty pleased with it, once I learned how to use it properly. The new versions of UltraEdit make E and Xedit pale by comparison. Yes, it is a whole new way of working. I hated getting away from the command line. I used to think that if you weren't doing it from the command line, you weren't a real programmer. However, I have learned that I can be much more efficient than I used to be by learning new ways of doing things.

UltraEdit has scripting language support that is very, very powerful. REXX is good, but UltraEdit uses JavaScript. It seems JavaScript is an important language to learn these days anyway. It can only help your resume to have it listed as a language that you are proficient in.

How painful was it for me to make the switch? Hey, I jumped from using DOS/DESQview, a Unix (not Linux) Server with XWindows, to Windows 95 and a Novell Server (because of the company I was working for), I was already complaining a lot.

It may be painful at first to have to get used to a new way of doing things, but rest assured, after you've had a few months under your belt learning all there is to UE and its powerful scripting language, the features, the ability to run your scripts on files from the command prompt, the ability to run command line utilities and pipe them through to be filtered into your editor and worked with... I could go on and on about the features that you will discover only after digging into it extensively, but let me tell you it will all be well worth it.

Yeah, I probably told a bit about my age telling you what I started out working with as editors, but I don't care. If someone like me can make the switch and learn to love it, you can too.

When it comes to editors that can handle the unicode properly, there is no better editor on the market. It is hands down the most powerful text editor available today, and it's on the Windows platform.

Personally, I've moved up to using UEStudio. It has all the features of UltraEdit, but adds quite a few extras to make it a full-fledged IDE instead of just the most powerful editor on the planet. Imagine an Integrated Development Environment that has an editor like that built in!

I often knock off a 20 line KEXX macro to handle some special case (like editting Wireshark telegrams that meet certain weird column-based criteria); how easy is it to do something comparative in UE?
It will be just as easy, once you learn JavaScript as well as you know KEXX. If it is simple enough to create a Macro instead of a script, you can "record" the macro, then play it back to finish your editing. I probably record and replay macros 10X as much as writing scripts, but scripts have their place for the real power.

Ah, yes. E, EOS2, EPM....

I contracted at IBM from 1990-1992. The funny thing was, I used Kedit before going to IBM, and by the time I was at IBM, I was using MultiEdit . I original started with Jim Wylie's Personal Editor (remember EWS?), but it was DOS 1.x, so it didn't support subdirectories; plus, putting PE.PRO in every damn subdirectory was a pain. I started with Kedit to basically be a PE that knew about subdirectories. From there, I went to IBM, but since IBM at the time was OS/2 1.x, with a single penalty box, I switched back to Kedit for OS/2 so I could run native, and haven't looked back.

I'm considering MultiEdit again (a friend loves it), but I'm scoping out UE first. Reviews seem kinder to UE than ME. Most of what I do these days is C++, XML, Perl, and Ruby. I've downloaded the UE demo, and have played with it a bit. It's... different. I've been reading some hyper critical reviews of UE (http://fileforum.betanews.com/detail/UltraEdit/976352095/1?all_reviews), but I've read several other glowing reviews, so I'm trying to do a fair Kedit/UE comparison.

I expect that whichever way I go, it will be painful enough that I want to select an editor that I can stick with for another 15 years before going through this again.

Kedit is considered Eastern Orthodox, UE seems more Western Orthodox (http://www.softpanorama.org/Editors/eoe.shtml).

I definitely miss the command line. The F10 in UE brings up a command window, but it's not the same.

Probably true. It certainly seems more verbose.

Compare

Code: Select all
UltraEdit.document[index].top();
UltraEdit.document[index].write("// Script Name: ");

to
Code: Select all
'top'
'text // Script Name: '

I remember using Desq (pre-DesqView) with X. Thankfully, I skipped Win9x and went straight to OS/2. One of the reasons I stuck with Kedit was that whether I was using DOS, OS/2, or eventually Windows NT, there was always a Kedit version. These days, DOS is pretty much a memory, as is OS/2, so compatibility with those platforms is no longer important.

I do see that UE has build in support for FTP, which is nice. Also telnet.

Thanks. I already do a lot of that by having Kedit macros that call DOSQ and run Take Command scripts which pipe stuff back to Kedit. I work on a lot of apps that generate tons of log data (300MB is not uncommon, spread over ~100 files), so what I typically do is flag certain log conditions, tag them with a unique id (say bdh, my initials), and then have Kedit grab the 300MB file, and using ALL to see the filtered lines, expanding as required to see the state. That sort of thing is beyond most of the other editors I've looked at.
rhapdog wrote:Yeah, I probably told a bit about my age telling you what I started out working with as editors, but I don't care. If someone like me can make the switch and learn to love it, you can too.
I think any of us with Kedit 3 digit serial numbers are probably of an age.

Not to be contrary, but have you looked at MultiEdit? It also claims to be the most powerful. I've got no dog in the race yet, I'm planning on kicking the tires of both (and maybe a dark horse called Zeus someone's mentioned: http://www.zeusedit.com/features.html). Zeus appears to be a next gen version of Brief, from back in the day. The only reason I even found it is that looking for a ME to UE comparison, the only thing close was this forum entry: http://www.zeusedit.com/zforum/viewtopic.php?t=200, which of course claims Zeus is better than either, but at least points out things about ME and UE I'll want to check).

Thanks for the help. My problem is that almost all of my peers are of the Visual Studio generation. The idea of a standalone editor is foreign to most of them. Although some do use Notepad++ or VIM, there's no one other than me using anything else. The idea of a commercial editor is foreign to them, and anything derived from an IBM mainframe is before most of them were born. Suffice to say, talking about XEdit features really shows the generational divide. I wasn't sure if anyone had taken the plunge from Kedit to UE, but the fact that you've done it, and recommend it, is probably the best recommendation I can think of for me to invest in UE and give it a fair shake.

If you want to do this long term, consider a lifetime license. That's the best way to go. Stay current. IDM is a strong company and isn't going anywhere. With the number of users they have world-wide, you will have support for your product for life.

These "bad" reviews are obviously from people who did not properly study or learn to use their editor. I will guarantee those complaining about slow startup didn't check to see that it was because of a slow network share, an antivirus monitoring program that was a bit haywire, or some other issue on their system. Those complaining about too many toolbars and getting lost in the options never studied about UE's Environments, where you can choose what to see and what not to see. I could debunk every criticism, but won't take time to do it here.

billdehaan wrote:Not to be contrary, but have you looked at MultiEdit? It also claims to be the most powerful.

Yes. I have. It just can't do everything that UltraEdit does. It is also considerably more expensive. For my money, UE is the best deal. They may "claim" to be the most powerful, but when I state that UE is the most powerful, it isn't just a claim from IDM, it is a claim by the People's Choice Awards, Shareware Industry, numerous magazine publications, and numerous 3rd party reviews.

If you Google for "Most powerful text editor for Windows", you will find many reviews that have a "list" of most powerful editors. I have seen "10 most powerful", "15 most powerful", "5 most powerful", etc., but have not once seen MultiEdit in a most powerful list. UE, in each of those, was stated to be the most powerful (at least the ones I looked at when I Googled this morning.)

I read that just now. Zeus is laughable compared to UE. This is also an old post, and some of the things stated about UE were either in ignorance, or have been fixed since then. Not one negative he listed is currently true of UE.

This is not true. When it comes to new releases, there can be advantages to each direction. Yes, UE gets the features added first. Then with that widespread release, bugs are invariably reported (as any program as complicated as UE will have) and subsequently fixed. When these bugs are squashed, and the product is refined even further, then a few new features are usually added to UES that never made it into UE, because UES is supposed to have more features.

The time frame can be a couple of weeks, or a month, sometimes as long as 2 months. This is not a make or break time period to wait on the features to migrate over to UES, especially considering that once you get those features, they will be stable and you won't have to patch it later after being frustrated by the bug you found.

The real way you need to evaluate it is do you need to "compile" your programs from projects. If you're coworkers are using Visual Studio, and you're working from the same compiler that they are, then you'll find that once you get UES up and running, it will offer you features to handle multiple project files to allow them to interact in ways you can't do with UE.

Seriously, take a good look at the UE/UES comparison before you make a final decision.
http://www.ultraedit.com/products/uestu ... ences.html

If you are going to make an investment, and take time to learn a product after you do, then you should seriously consider UES. If I were doing stuff that others were designing in Visual Studio, then I would be using UES. I'm actually using UES for Delphi 2010 replacement, and also for a number of PHP site projects. It works with the frameworks flawlessly.

Also, as far as "going back", I read recently that someone requested their lifetime license for UES be "downgraded" to UE, because they no longer needed the UES features. They were able to do so. To get the lifetime license for UES, after you have UE, you still have to pay again, although you get a loyalty discount. Something to consider. I can't imagine you doing that kind of programming and not being able to use the full power of UES, but I can see you regretting not going that route should you settle for the smaller package.

An excerpt from http://www.softpanorama.org/Articles/or ... tors.shtml
I would like to stress that an editor is probably the most important tool for programmers, therefore one needs to choose it wisely. A popular consideration that easy to learn editor (for example Pico or Notepad) is the best does not withstand any critique. An editor is too important tool for programmers to settle for the basic capabilities and it's a big disadvantage to select a mediocre or even primitive solution just because it's simple to learn. Any professional programmer needs a professional editor.

The main problem that I see is that people tent to stick to whatever editor they got used to first and even became emotionally attached to the "first choice".

The author argues that programmable editors are worth studying like programming languages and a powerful editor is huge advantage from the point of view of reaching high productively (and avoiding many typical frustrations).


That is good advice for anyone.

...Well, just one day of testing showed me that at least the speed complaint didn't apply to me. I've not seen the "crashes every day" problem either, of course. I already know from Sturgeon's Law that 90% of the complaints are just bellyaching, that's why we have tryout periods.

I can already see how people could be overwhelmed by UE. It took me a bit of time to find how to set the environment to "Programmer". As always, it's obvious to those familiar with the product, but there are staggering number of pulldowns, menu options, and etc. in UE.

As I said, I used ME back in the late 1980s, with the DOS version. Back then, it was quite competitive, which means absolutely nothing today. I noted that their price is higher (ME: $199, Zeus: $99, UE: $59-$89+). Obviously, I'd prefer cheaper, but I'm not going to disqualify based on price. Adjusting for inflation, ME today at $199 is cheaper than Kedit was at $125 in 1985. The time investment I'm going to put into whichever editor I end up choosing will certainly exceed $100 over the years.

Of course, power is in the eye of the beholder. What's keenly important to web developers may not matter a bit to someone doing embedded assembler, and vice versa. A co-worker told me he considers EditPlus to be the most powerful editor. When I asked him what scripting features he said, he answer "I'm not sure if it has any. If it does, I might have just removed the menu item for it, since I don't use macros". Lots of people claim Eclipse is the best of breed, but when I played with it, I found I couldn't even remap the keyboard. I was asked "Why would you want to do that?".

Certainly the comparison is out of date. Looking at Zeus, I'm not about to rule it out without further checking. Especially since both Zeus and UE use javascript for a (of one of the) scripting language, it should be an easy comparison.

Oh, I agree fully. I still remember when I got my August 1985 issue of "Computer Language" magazine (they of the Jolt awards), where they devoted the cover story to comparing all of the editors on DOS at the time (Brief, Qedit, Kedit, all the various Unix and big-iron ports, etc). Just checking my Kedit macros directory, I see I've written 40,383 lines of macros over the years. The idea of just using any editor "as-is" just off the rack is anathema to me, although fairly common.

I think that's why so many people love Notepad++. Not to take anything from it, it's a terrific out of the box editor. But even with the plugins, the extensibility is pretty limited. If it does what you need already, it's great. If it doesn't, you're stuck.

To me, when it doesn't do what I want out of the box, that's where the real issue is. That's when I can judge how long it takes me to be able to get it to do what I need. A non-scriptable editor may be very powerful, but I notice most people who use them end up adjusting their work habits to confirm to the editor, rather than the other way around.

Usually, when someone shows me a cool feature from their editor and asks if my "20th century" Kedit can do that, the usual answer is "not yet, but give me an hour". But with unicode, and things like Kedit's line-only orientation (as opposed to keyword), that's increasingly become "no". That's why I'm seeing if UE is extensible enough to make it back into the "not yet, let me write a script" column.

I was thinking about that. With a little modification, you may be able to convert your KEXX macros into REXX, then run them from a REXX Interpreter like Regina as a Tool from within UltraEdit. Certainly not all macros will be able to be converted, but most should, I would think. Some may not require converting at all, if it doesn't use the KEXX specific subset.

Something to think about.

I actually use a number of PHP scripts and run them against my current document at times, because that is something I code in often. You could implement any number of scripting languages in this way, but you'll miss out on the UltraEdit application object that has been included in UltraEdit's version of JavaScript. It allows you to perform some of UltraEdit's functionality without having to reinvent the wheel, which is nice.

billdehaan wrote:Just checking my Kedit macros directory, I see I've written 40,383 lines of macros over the years.

Yeah, I'd definitely see if some of that can be converted to REXX and run through Regina. No sense in wasting it. If you could do that, you'd probably have something serious to share with the community.

LE - Lukyanov Editor

Great light-weight Windows style editor from Alexander Lukyanov.

LE has many block operations with stream and rectangular blocks, can edit both unix and dos style files (LF/CRLF), is binary clean, has hex mode, can edit text with multi-byte character encoding, has full undo/redo, can edit files and mmap-able devices in mmap shared mode (only replace), has tunable syntax highlighting, tunable color scheme (can use default colors), tunable key map. It is slightly similar to Norton Editor, but has more features.

AEditor – Freecode

AEditor is a programmer's editor for Windows, Unix, and Mac OS X that relies on the fox toolkit. It can do syntax coloring of Ruby and C++ files. It's easy to change the color theme. Most things are customizable. It is written in Ruby and is carefully unit-tested (it has 421 tests). It is written in only ~5500 lines of code, so it should be easy to grasp and extend.

[Nov 23, 2012] Highly programmable non-Emacs editor?

December 24, 2003 | http://www.fogcreek.com/
Junkster

I'm an editor junkie. I've used dozens of them. I'm currently using with EditPlus for Windows, but it's still not my perfect editor. These days, it should be easy enough to have a more componetized editor: a simple visual display component, plus ways of shooting text to Perl or Python (or your favorite language) to do fancy grunt work. Instead, text editor authors tend to take a GUI-heavy approach, building everything into one, monolithic application. I have seen two alternatives. One is Emacs. I don't want to get into a flame way about Emacs. I've used it. But it's more a lifestyle than a text editor. And then there's Wily, which is a clone of an editor for Plan9 called ACME. Wily looks interesting, but it is a UNIX-only program--no Windows version. And, okay, someone is going to mention vi. Yes, I've used vi. I've written tens of thousands of lines of code with vi. But in the end both vi and Emacs strike me as editors from another era. The cleanliness that comes from an editor like EditPlus or BBEdit (a Mac editor), is something I don't want to lose.

Junkster

Extreme programmability is important for several reasons. The first is that it offers up a lot of options, letting you do things that the author hadn't thought of. For example, I often use non-mainstream programming languages that would benefit from being syntax colored in non-standard ways (certain types of lines colors a specific way, rather than just keywords). I'd also like to be able to extend an editor to context-sensitive tab completion; build custom, interactive project management systems, etc. All of this stuff is business as usual in Emacs. But Emacs is a relic of the past otherwise.

Text munging is easy. We have entire programming languages devoted to it. An editor just needs to be a thin interface with hooks to routines written in such a language. It shouldn't be a monlithic application. I'm surprised that no one has followed this road, other than Stallman's Emacs.

Mac

Visual slickedit is a good alternative. But slick-c is a crappy hacked scripting language. I have written dozen of functions to do things that I want similiar in emacs and vim, but slick-c just can't live up with any other scripting languages that I have used (lisp, perl, python, js).

And the source code that came with vslick are not horrible mess. Good luck trying to learn and understand those source code - it's like I haven't had enough reading my peer's code...

Just my $0.02

And the source code that came with vslick are JUST horrible mess.

BTW, the API provided by slick-c is very inconsistent (I'm not saying elisp is WAY better, but at least it's still managable...)

christopher baus (www.baus.net) Wednesday,

I used to be a emacs bigot, but I'm over it. I still write code nearly every day in Emacs on Unix, and VC++ on Windows, but having seen a demonstration of XCode, I've decided to move my Unix development over to the Mac.

What I think is interesting is that emacs it is completely unique approach to application development, and it worth learning just for the alternative look at software applications. I has certainly influenced Gosling's (who used to work on emacs), NeWS and Java -- not to mention autocad which orginally had a lisp based scripting language. Lisp had a VM and garbage collection a million years ago.

Emacs is powerful enough that it is still useful 25+ years after it was orginally written. But I'm not a student anymore, and I don't have time to endlessly tune my .emacs and custom makefiles. Plus I've grown so used to modern IDEs that emacs + gud is painful.

What I think might be interesting is a editor or platform built with emacs as the model, but assuming a modern windowing environment. Maybe we have it in .NET, but it doesn't seem quite the same.

Junkster

Yes, I've used UltraEdit. It's essentially the same as EditPad Pro and EditPlus. But they're all very closed systems (in the extensibility sense, not the open source sense). An editor can just be shell and use Perl, for example, to do the real grunt work.

I have also tried vim, which I consider to vi plus some much needed extensions. It still comes across as dated and clunky under Windows. The interface in a typical Windows editor is so invisible compared to vim and Emacs.

Phillip J. Eby

jEdit. It's scriptable with Jython and BeanShell. It has syntax highlighting for a bazillion languages, and it has a flurry of plugins available for every imaginable want or need. I use the XML plugin, the LaTeX plugin, the project management plugin, and there are many many many more available out there. It's hugely configurable, lots of GUI options. Extremely extensible, cross platform, and of course it's FLOSS.

It's written in Java, and startup takes a while on older machnes; 20-30 seconds on an old 400Mhz machine. My newer machines start it in 10 or 15. But I've never had any performance issues once it's loaded, even on slower machines.

Oh yeah, the syntax highlighting also configures lots of nifty features like autoindenting, block comment, bracket matching (tag matching in XML mode), code folding, and suchlike features. It's a *very* complete programmer's editor, and should not be confused with Eclipse (which is a generic IDE/tool platform with some editing capabilities, and whose plugins are heavily slanted towards Java development).

Oops, forgot to include the URL: http://www.jedit.org/

Slartibartfast

Interesting that nobody mentioned Multi-Edit. http://www.multiedit.com/

Their kernel is Delphi, then everything else is built using CMAC, their scripting language. Their community is very active, and a new version was just released.

I just played a bit with jEdit on my WinXP notebook. Can someone please explain to me why the font rendering sucks like a typical Java application? No AA. My XEmacs looks nice on Win XP. It's also a bit embarrassing that you have to reload the entire app to change the text font. (XEmacs is a fork of Emacs, not the X11 version)

There seems to be no viable alternative to Emacs or Vim...

C Rose

jEdit does offer anti-aliasing of text, and you enable it via Utilities -> Global options... -> Text Area. Choose Smooth text and Fractional font metrics (depending upon system spec.).

jEdit is an excellent modern editor. Emacs suffers from massive complexity -- there's so much to remember. The modal design of vi/m is just weird.

Pakter

I have JEdit installed, and it's not bad at all. JEdit had the same plugins as Eclipse, and more. But I don't feel "at home" with it. Like Junkster, I use mostly EditPlus. As Junkster probably knows, you can do a lot with EditPlus, though it's not extensible in the usual sense. At home, I also use ConText, which is similar to EditPlus, just a little less powerful.

Bored Bystander

I also use Multi-Edit and have ever since its DOS days. ME is a great value ($80-$120 or so depending on upgrade or new purchase) since it includes features like file differencing and a generalized compiler interface to act as a sort of self contained IDE to host command line tools.

The only drawback I've ever seen to ME is that you have to customize its key command mappings quite a bit in order to get reasonable behavior (ctrl-F for search, F3 for search again, Ctrl-F4 for close window, etc). ME has very strange notions about common shortcuts. And I have not found a way to make these definitions portable to a new system. (Or, I just don't know the MultiEdit configuration system as well as I "should".) So every time I move ME to a new PC I have to spend about 1/2 hour re-customizing it.

But you're wrong Aaron. If you are a software developer than you really can improve your productivity significantly by learning your editor thoroughly.

As a professional developer I spend much/most of my day in my editor (vim). It's my paintbrush with which I create beautiful worlds. I'm just not going to blithely pick up and use any old brush.

I'm not exactly sure I understand the chain of creative or physiological process that occurs when I write software but I do know, for me, that vim is part of it.

Subject: Re: How many other editors in use

Editors are like OS's, personal preferences to some extent. I agree with several of
the comments above that knowing your editor well is a major plus.
Consider your "needs" and what you might like to do, how extensible it should be,
and pick one.

Building on past knowledge is surely an advantage but looking at new
editors can be enlightening. I found one, Manfield's KEdit, many tears back and
embraced it :)

It isn't free, has some quirks, and the company is dropping support. It is quite nice, has a neat extensible macro language, several sites that provide sample macros, and people who use it who are extremely helpful.

The Editors Group is interesting but doesn't provide the "gee, I'd like to see only code that begins to the left of this column" or "what data is unique in these columns." Maybe an Editors Concepts group is needed. But, to address the initial thread start, if you have a question on Joe or whatever, ASK!

I've posted notifications here of KEdit's changes as well as questions and been
happily surprised. YMMV!

I think the reason most questions are about vim is because other editors
don't provide so many "hidden" tricks" or offer so much functionality.
I use vim and occasionally emacs, but in different contexts: I prefer
vim for config file editing but emacs for email and longer works. But
in GUI environments I mostly enjoy jedit, a java editor that works
equally well on every platform I use - that's handy. I carry my macros
and config files on a USB key and can instantly work the way I like to
on any machine I use. I also find it easier to customize than emacs,
whose lisp I've never really gotten the hang of.

But if I don't post any questions about jedit here it's because it's been pretty easy to figure out and I haven't got any questions to ask. Still, I think a comp.editors.vim group would be appropriate, since the emacites have a separate group.

For the record, I, too, like switching around my editors from time to time, but mostly because it's fun to learn new software. I've used jed, and joe as well: they're fun for what they are. Joe is actually good on usenet because it defaults to hard wrapping, something I want on usenet but don't want on longer works. (yeah yeah yeah, vim and emacs can do that too. I get it, I get it).

Cheers.

Newsgroups: comp.editors From: DMcCunney <dennis.mccun...@gmail.com> Date: Sat, 18 Apr 2009 09:58:39 -0700 (PDT) Local: Sat, Apr 18 2009 11:58 am Subject: Re: How many other editors in use Print | Individual message | Show original | Report this message | Find messages by this author Coming late to this party...

I think which editor you use depends upon where you start and what you grow accustomed to.

For instance, the first editor I used was back in the late 70's at a bank. It was a product called ACEP, intended to replace TSO/SPF on IBM mainframes running OS/VS1 and OS/MVS (now zOS). It was accessed through 3270 terminals or compatibles. 3270s were "block-mode" terminals, not character mode, and had a completely different idea of full-screen editing than what most people think of. On a 3270, you moved the cursor around the screen, made changes, pressed the Submit key, and the entire *screen* was sent to the host. ACEP's developers developed under Unix, and it had features inspired by Unix. When my shop replaced ACEP with "real" TSO/SPF, I thought it a step backward.

This was back when the IBM PC was first becoming popular in corporate environments, and Lotus 1,2,3 was forcing everyone to upgrade theier 256KB PCs to a full 640KB of RAM to accomodate huge Lotus spreadsheets. So the second editor I learned was WordStar. Back then, WordStar was probably the second editor you learned, because the one you preferred might not be available on the machine you had to use, but WordStar probably was.

The third editor I learned was vi, because I left the bank and found myself working for a small Unix systems house. This was the early 80s, and Vim wasn't around -- vi was the original Bill Joy product, running under AT&T System V. Vi was a rude shock, until I started to grasp the design concepts, whereupon it made sense. (And I found a set of macros that made the arrow keys work in insert mode, which eased a lot of the pain...)

Vi and WordStar shared.a design concept: they were keyboard independent. If you had a qwerty keyboard with a Control key, you could use them. It made sense, because a lot of odd things got used as terminals on early Unix systems, some of which didn't *have* arrow keys or F-keys, and there was almost as much variation in the early CP/ M systems on which WordStar originated.

As I started using PCs more, back in the MS-DOS days, I kept some WordStar fluency because many PC editors either used the WordStar command set or could be told to. For that matter, I loaded a WordStar emulation package in Gnu Emacs on *nix boxes to avoid retraining my fingers, and wrote a WordStar emulation macro package for the MicroEMACS editor I ran on the PC.

In the process, I got interested in editor design and implementation, and collected them. I have a hundred or so here for various platforms, and am aware of many more. (Like, someone actually wrote a partial vi clone for the Commodore 64...)

Which I use depends on what I'm doing. My standard editor on the PC under Windows XP is Don Ho's Notepad++, with a tabbed interface and based on Neil Hodgson's Scintilla edit control, which provides code folding and syntax highlighting for a large number of languages. http://http://notepad-plus.sourceforge.net/uk/site.htm

On Solaris, I use vi. On some flavors of Linux, I use Vim, but I might as well be using vi - I have no need for and have never used most of the fancy features Vim implements.

There are a number of other things in the mix. For instance, I have an old Fujitsu Lifebook running Puppy Linux. Puppy is intended for lower end hardware (and thre are people reporting running it on P200s with 64MB of RAM). The Puppy devs make a point of a small distribtion (the ISO is about 100MB), and do various things to save space. For instance, Albrecht Kliene's e3 editor is bundled and linked as vi for console usage. e3 partially emulates vi, emacs, WordStar, Pico, and Nedit. Which personality it assumes depends upon which name it was called by. http://www.sourcefiles.org/Editors/Console/e3-2.7.0.tar.gz - tarball with source and binaries for DOS, Windows, Linux, and *BSD

The standard GUI editor on Puppy is Geany, a cross-platform editor based on Scintilla, with tabbed interface, code folding, and syntax highlighting. http://www.geany.org/Main/HomePage

There are a few things I'm looking at in the background but don't use regularly. One is IBM's open source Eclipse IDE. Eclipse is written in Java, and will run on anything with a current Sun JVM. While intended for Java development, it can be used for a large number of other languages, and is extensible through plugins. Eclipse seems to have largely killed off the commercial IDE market. MS Visual Studio is still out there for the Windows only folks, and Embarcadero Technologies (formerly Codegear, formerly Borland's compiler and tools division) still offers things like C++ Builder and Delphi, but they seem to be catering to an existing market which is too deeply embedded to make switching easy. Everyone else just opts for the free, open source product. :-) http://www.eclipse.org

Another interesting direction is ActiveState's Komodo Edit, which is an open source component of their commercial Komodo IDE. Komodo is built on the Mozilla code base, using the Gecko rendering engine to display the editor on the screen. Because it's based on Mozilla code, it's cross platform, and it can be be customized with themes and extensions. Komodo incorporates Scintilla, so code folding and syntax highlighting are part of the package. http://www.activestate.com/products/komodo_edit/

There are over 1,000 different text editors out there for various platforms, based on a variety of paradigms and intended uses. I don't believe in a "one-size-fits-all" editor, and use what best suits what I'm doing at the moment. I roll my eyes at emacs vs vi Holy Wars.

Folks interested in exploring a bit should visit http://TextEditors.org, a wiki devoted to the topic. If you know of something not listed, or have updates/corrections for stuff that is listed, please add them.

DMcCunney

I wish the new Lisp version John Graham et al are working on would move beyond the experimental and "in flux" stage already, and continue to make an interpreter that can somehow make use of all the useful Python libraries

Like he points out himself; Lisp isn't much in use, cause except for command shell scripts, its tough to use for real world stuff, cause there's not much in the way of libraries... I don't know about the interpreter / compiler situation

I liked Dr. Nikolai Bezroukov's commentary in his commentary on editors on his Softpanorama website. He talked about macro languages for text editors, and was less than thrilled with Emacs using a dialect of Lisp, because he felt the language ought to have some use ouside of the editor, and what other use of Lisp did the majority of Emacs users make? Eric S. Raymond was going on a while back about what Emacs got wrong, and how much better Python would be for the purpose. When I said "So rewrite Gnu Emacs to use Python instead of Lisp." the response was "Don't tempt me..."

I have to agree. I have Gnu Emacs here, but the only use I made of elisp was years back, learning enough to hack my .emacsrc to properly support the various special keys on the machine I was running it on. I've had no cause to touch it since.

[May 9, 2008] What is a folding editor

Most folding capabilities in editors such as GNU Emacs and most folding editors such as Origami and fe, are inspired by the Inmos Transputer Development System. After several years, folding/outlining capabilities in text editors are not as exotic as they used to be, but they are still far from being well known. This document explains what "folding" is all about.

A folding editor extends the principle of tree structured directories to editing text files. This allows the simultaneous display of large amounts of text by folding sections of text away behind a descriptive heading. This results in a tree structure very similar to a subdirectory structure of, for example, UNIX. By suitable structuring of a text it should be possible, in most circumstances, to ensure that no display exceeds a single screen at any time. To access text that is folded away, you open the fold, in which case the contents are displayed in context of the surrounding text. The advantage of this system is that it eliminates the need for seemingly endless paging through long files to find the section of interest, allowing you to move down the tree structure, following the (hopefully) descriptive headers to locate the text you require.

[May 9, 2008] Code Browser - A Folding Text Editor

Code Browser supports only the marker-based folding. See Introduction to Folding page for the explanation.

Code Browser is a folding text editor for Linux and Windows, designed to hierarchically structure any kind of text file and especially source code. It makes navigation through source code faster and easier.

Code Browser is especially designed to keep a good overview of the code of large projects, but is also useful for a simple css file. Ideal if you are fed up of having to scroll through thousands of lines of code.

See the Introduction to Folding page if you want more information on text folding and the way it is implemented in Code Browser.

It supports syntax highlighting for all major languages and custom syntax highlighting can also be added.

Although Code Browser was initially designed to edit programs, it can also be used for different tasks such as plain text outlining or understanding existing source code. I've added a page with tips on alternative uses.

freshmeat.net Project details for Cooledit

Cooledit is a text editor for the X Window System. It contains a built-in Python interpreter for macro programming, and it includes a rich set of utilities and features. It has multiple edit windows and a beautiful, intuitive user interface that requires no tutoring to learn to use. It can be used as a programmer's IDE and has syntax highlighting for a large number of programming languages. It contains an interactive graphical debugger for C/C++ programs.

Code Browser

Code Browser is a folding and outlining editor for Linux and Windows.

The editor is between a traditional text editor, a smalltalk class browser and a web browser like mozilla. It displays a structured text file (marker-based folding) hierarchically using multiple panes.

It is especially designed to keep a good overview of the code of large projects. Ideal if you are fed up of having to scroll through thousands of lines of code.

See the Introduction to Folding page if you want more information on text folding and the way it is implemented in Code Browser.

It supports syntax highlighting for all major languages and custom highlighting can also be added. For other editor's features, see Features.

ConText Editor

A very interesting Windows editor. Flexible customizable syntax highlighting. Well organized features

This syntax highlighting editor supports numerous programming languages including C/C++, Delphi, Pascal, Java, JavaScript, Visual Basic, Perl, HTML, SQL, FoxPro, 80x86 assembler, Python, PHP, Tcl/Tk, etc (you can customize the syntax highlighting). Other features include code templates, customizable help files for each file type, export to HTML/RTF, file conversion (DOS, Unix, MAC), bookmarks, commenting, uncommenting code, capturing the output from console applications, etc. It's a Windows editor.

CUTE User-friendly Text Editor

CUTE is a text editor that is extensible using Python. It supports projects, syntax highlighting of various programming languages (C, C++, C#, Java, Python, JavaScript) as well as HTML (etc), multiple documents (tabbed or child frame), ctags, auto-completion, search and replace with regular expressions, bookmarks, undo/redo, has an integrated file browser, themes, key macros, etc. Binaries (executables) are available for Linux. The source code is released under the GPL and can be compiled for Windows

Linux.com Some Linux apps are small wonders

13K in size for the editor that's something from DOS era :-). It is written in NASM assemblerThat's a great achivement and it refreshing to see that not all useful software is bloatware !!!

e3 text editor

The e3 console text editor takes minimalism to the max - the binary is a minuscule 13KB in size! So why use this instead of [insert the name of your favorite editor here]? If you're anything like me, you'll find a lot of your editing tasks are very short -- little more than tweaks. e3 starts instantly and has all the basic features you could want, including find/replace, block cut/copy/paste, and undo. For complex tasks I use a more feature-packed program, but for a quick change to /etc/fstab or something similar, this little editor wins every time.

e3 also does its best to be ubiquitous. It works on a whole host of operating systems, and perhaps best of all, it supports keyboard mappings that emulate WordStar, Pico, emacs, vi, and Nedit. You can hardly fail to feel at home with it.

Exuberant Ctags Version 5.5.2 [17 September 2003]

[Sept 12, 2003] The Right Size for an Editor

Eric Raymonds view on the subject. IMHO he did not understand the real tradeoffs that make vi a great editor for so many years, but he at least is able to site right people ;-). With all due respect to RMS, Emacs is definitely anti-Unix type of editor :-).

Is Emacs an Argument against the Unix Tradition?

The traditional Unix view of the world, however, is so attached to minimalism that it isn't very good at distinguishing between the adhocity-trap problems of vi and the optional complexity of Emacs.

The reason that vi and emacs never caught on among old-school Unix programmers is that they are ugly. This complaint may be "old Unix" speaking, but had it not been for the singular taste of old Unix, "new Unix" would not exist.
-- Doug McIlroy

Attacks on Emacs by vi users - along with attacks on vi by the hard-core old-school types still attached to ed - are episodes in a larger argument, a contest between the exuberance of wealth and the virtues of austerity. This argument correlates with the tension between the old-school and new-school styles of Unix.

The "singular taste of old Unix" was partly a consequence of poverty in exactly the same way that Japanese minimalism was - one learns to do more with less most effectively when having more is not an option. But Emacs (and new-school Unix, reinvented on powerful PCs and fast networks) is a child of wealth.

As, in a different way, was old-school Unix. Bell Labs had enough resources so that Ken was not confined by demands to have a product yesterday. Recall Pascal's apology for writing a long letter because he didn't have enough time to write a short one.
-- Doug McIlroy

Ever since, Unix programmers have maintained a tradition that exalts the elegant over the excessive.

The vastness of Emacs, on the other hand, did not originate under Unix, but was invented by Richard M. Stallman within a very different culture that flourished at the MIT Artificial Intelligence Lab in the 1970s. The MIT AI lab was one of the wealthiest corners of computer-science academia; people learned to treat computing resources as cheap, anticipating an attitude that would not be viable elsewhere until fifteen years later. Stallman was unconcerned with minimalism; he sought the maximum power and scope for his code.

The central tension in the Unix tradition has always been between doing more with less and doing more with more. It recurs in a lot of different contexts, often as a struggle between designs that have the quality of clean minimalism and others that choose expressive range and power even at the cost of high complexity. For both sides, the arguments for or against Emacs have exemplified this tension since it was first ported to Unix in the early 1980s.

Programs that are both as useful and as large as Emacs make Unix programmers uncomfortable precisely because they force us to face the tension. They suggest that old-school Unix minimalism is valuable as a discipline, but that we may have fallen into the error of dogmatism.

There are two ways Unix programmers can address this problem. One is to deny that large is actually large. The other is to develop a way of thinking about complexity that is not a dogma.

Our thought experiment with replacing Lisp and the extension libraries gives us a new perspective on the oft-heard charge that Emacs is bloated because its extension library is so large. Perhaps this is as unfair as charging that /bin/sh is bloated because the collection of all shellscripts on a system is large. Emacs could be considered a virtual machine or framework around a collection of small, sharp tools (the modes) that happen to be written in Lisp .

On this view, the main difference between the shell and Emacs is that Unix distributors don't ship all the world's shellscripts along with the shell. Objecting to Emacs because having a general-purpose language in it feels like bloat is approximately as silly as refusing to use shellscripts because shell has conditionals and for loops. Just as one doesn't have to learn shell to use shellscripts, one doesn't have to learn Lisp to use Emacs. If Emacs has a design problem, it's not so much the Lisp interpreter (the framework part) as the fact that the mode library is an untidy heap of historical accretions - but that's a source of complexity users can ignore, because they won't be affected by what they don't use.

This mode of argument is very comforting. It can be applied to other tool-integration frameworks, such as the (uncomfortably large) GNOME and KDE desktop projects. There is some force to it. And yet, we should be suspicious of any 'perspective' that offers to resolve all our doubts so neatly; it might be a rationalization, not a rationale.

Therefore, let's avoid the possibility of falling into denial and accept that Emacs is both useful and large - that it is an argument against Unix minimalism. What does our analysis of the kinds of complexity in it, and the motives for it, suggest beyond that? And is there reason to believe that those lessons generalize?

9.5. Fold2Web

Developer: Bernhard Lang <lang@tu-harburg.d400.de>
Version: V0.8
Hardware: MSDOS
Languages: All (must allow comment lines)
Formatter: LaTeX
Availability: Anonymous ftp from:

Readme: In distribution

Description:

The idea behind the Fold2Web tool is the following: A programmer can write his program source with a folding editor and later map the folded source files automatically to WEB-files. The generated WEB-files can then be modified by inserting required documentations.

The advantage by starting program developement with original sources is to get short design cycles during the compile/debug steps. By using a folding editor the global structuring information can be already captured in folds during this developement phase. Fold information is typically stored in comment lines and thus will not affect the
efficiency of the compile/debug design cycle.

Some folding editors and a folding mode for the emacs are available (e.g. see our FUE folding editor for MSDOS machines which is a modified micro emacs. Pick it at kirk in directory /pub/fold2web).

After reaching a stable version of a program source its time to convert the source file to a WEB-file and do the program documentation. Fold2Web is written to convert folded source text of any programming language to nuweb files. The folded structure is kept by mapping folds to scraps. Fold markers which differ between languages due to different ways of specifying comments can be configured for each language.

Good results can also achived when given but poor documented program sources have to be modified. Such sources can be folded using a folding editor to extract the global structures. This offers a global view tothe program structures and help to understand its functionality. Furthermore the program code is not affected, only comment lines are
inserted. Once folded the program source can be automatically translated to a WEB document using the above tool.

Fe User Guide

A few words on the design of fe

After working with Origami for many years, both as user and developer, I have decided to implement a new folding editor: fe. There are a few basic design decisions which make it different from Origami:

Origami is partially written in its extension language. While being more of a hack in the beginning, it has changed to a full programming language. As such, it takes time to be learnt. Code written in it is not well usable by most people who don't know it. The conclusion for fe is not to support any extension language, neither a homebrew one or a standardised language, like scheme. Instead, fe is implemented as a library of basic editor primitives. Its is easy to write your own editor by using that library. fe can be modified easy without having to learn a new programming language. The editor also stays small and elegant this way, while Origami has to offer zillions hooks for extension functions.

Origami implements folds as double-linked n-trees, with nodes being single lines or folds. This allows quick manipulation of folds or lines. But region oriented functions become hard to implement and are mostly not too quick any more. fe uses a gap buffer to store text, folds are represented as meta-characters in the flat buffer. This means basic fold primitives are slower than in Origami, but more complex and region oriented functions are faster. During development of the first prototype of fe, I found many functions in Origami not to be as canonical as they should be after I implemented them in fe. From my past experience, the performance of typical personal computers to have increased by a factor of 10 every 5 years in the last decade, so the circumstances for editor design have clearly changed over time.

Folding has its merits, because it adds a structure to flat files. But, it also means that by bad structure design and badly commented folds the file will get harder to understand, not easier. This can happen up to the point where you want all folds to be gone to see what the file contains. If you need to keep many folds open during development to see their contents, you are probably preparing that situation at least for others. Although in general I don't like programs forcing me to do something, fe makes an exception here for two reasons: If the structure is obvious, you want the editor to close folds for you automatically. If it is not, you want to recognize that before it is too late. For that reason, fe closes all folds when you leave them. If you want to transport code from one fold to another, just split the current display and edit the file at two places. If both places are sufficient far away from each other, that's what you even had to do if you could leave folds open. \"}}}

Folding has its merits, because it adds a structure to flat files. But, it also means that by bad structure design and badly commented folds the file will get harder to understand, not easier. This can happen up to the point where you want all folds to be gone to see what the file contains. If you need to keep many folds open during development to see their contents, you are probably preparing that situation at least for others. Although in general I don't like programs forcing me to do something, fe makes an exception here for two reasons: If the structure is obvious, you want the editor to close folds for you automatically. If it is not, you want to recognize that before it is too late. For that reason, fe closes all folds when you leave them. If you want to transport code from one fold to another, just split the current display and edit the file at two places. If both places are sufficient far away from each other, that's what you even had to do if you could leave folds open.

History

Salon 21st The Xy files BY AMY VIRSHUP |

FOR THE REST OF THE WORLD, XYWRITE IS HISTORY --
BUT TO ITS DEVOTEES, THE ANTIQUATED WORD PROCESSOR STILL RULES.

Not long ago, a writer friend and I were talking software (there's a sentence I never thought I'd write) -- specifically whether we were Luddites for resisting a Windows 98 upgrade. Well, she said, she hardly felt out-of-date, since most of her publishing-world friends were still using XyWrite. I was stunned. I hadn't even heard the name in years, and suddenly I'd learned that, in a world in which six months is a generation, there lingered a dedicated cadre of loyalists to a program that hasn't been upgraded since 1993, that still runs best in DOS, that isn't compatible with most printers, and that has all but vanished as a commercial product. It was like finding out that a cargo cult was operating down the hall from my apartment.

For those of you unfamiliar with XyWrite -- the "GOD of word processors," as one poster to alt.folklore.computers recently put it -- the program was an offshoot of ATEX, which in the '80s was the standard in newspaper and magazine editorial hardware and software. It was created in 1982 by an ATEX programmer named David Erickson, who'd bought a PC and was unhappy with the word processor that came with it. So Erickson decided to write his own, and not long after he and another employee left ATEX to set up shop as XyQuest.

XyWrite was fast, it could do things no other word processor at the time could (like open two windows simultaneously), and because of the nature of the underlying programming language, XPL, it could be endlessly customized. The screen was a blank page with a command line at the top (hitting F5 would take you there), and when you wanted XyWrite to do something, you simply typed in an English-language command (such as "print" to print a file) or used one of your own custom keystrokes to carry out the task. It was defiantly not a "what you see is what you get" program, but it was extremely transparent, with all the formatting information easily viewable. And it was an instant hit among professional writers and editors, many of whom, um, borrowed their copies from their employers on a single 5 1/4-inch floppy -- mine, I confess, came from New York magazine, circa 1984.

Nancy Friedman was editorial director at Banana Republic when the clothing retailer started using XyWrite (version 2). "I loved it," says Friedman. "All of a sudden I was using this program that thought the way a writer thinks. All other word processing programs were created for secretaries -- they're all about creating standard one page documents. This one really expected that I was doing sophisticated editing and writing."

High-profile devotees included television's Brit Hume, John Judis of the New Republic and high-tech guru Esther Dyson. Critics called it the "Porsche 911 Carrera" or the "velociraptor" of word processors. And as much as they admired the software, users also loved the scrappy, down-home nature of the company: Erickson would sometimes answer tech support calls himself, and XyQuest was headquarted in decidedly unglamorous Billerica, Mass. "I was always so happy driving through Billerica knowing they were working to update XyWrite," remembers one writer who had occasion to pass through town in XyWrite's heyday. "It sounds so dopey, but that's how it was."

But XyQuest's marketing was never as good as its software, and it lacked the resources to compete with the big boys -- like WordPerfect, which the XyWrite faithful held in contempt. Then, in early 1990, IBM stepped in. The computer giant announced it was hooking up with XyQuest to create a new product, called Signature, based on the XyWrite model, and it looked like XyWrite was about to join the commercial mainstream. Instead, IBM delayed the product for a year and a half -- then, with boxes printed and diskettes ready to go, decided it was getting out of the software business altogether. A reconstituted XyQuest tried to sell the program on its own (renamed XyWrite 4), simply slapping stickers over the IBM logos on the boxes, says Tim Baehr, then a XyQuest programmer. But "sales just got lower and lower. We were bleeding money."
