==============================================================================

1. Introduction windows-intro windowLINK

Summary:

A buffer is the in-memory text of a file.

A window is a viewport on a buffer.

A tab page is a collection of windows.

A window is a viewport onto a buffer. You can use multiple windows on one

buffer, or several windows on different buffers.

A buffer is a file loaded into memory for editing. The original file remains

unchanged until you write the buffer to the file.

A buffer can be in one of three states:

active-bufferLINK

active: The buffer is displayed in a window. If there is a file for this

buffer, it has been read into the buffer. The buffer may have been

modified since then and thus be different from the file.

hidden-bufferLINK

hidden: The buffer is not displayed. If there is a file for this buffer, it

has been read into the buffer. Otherwise it's the same as an active

buffer, you just can't see it.

inactive-bufferLINK

inactive: The buffer is not displayed and does not contain anything. Options

for the buffer are remembered if the file was once loaded. It can

contain marks from the viminfo file. But the buffer doesn't

contain text.

In a table:

state displayed loaded ":buffers"

in window shows

active yes yes 'a'

hidden no yes 'h'

inactive no no ' '

Note: All CTRL-W commands can also be executed with :wincmd, for those

places where a Normal mode command can't be used or is inconvenient.

The main Vim window can hold several split windows. There are also tab pages

tab-page, each of which can hold multiple windows.

==============================================================================

2. Starting Vim windows-startingLINK

By default, Vim starts with one window, just like Vi.

The "-o" and "-O" arguments to Vim can be used to open a window for each file

in the argument list. The "-o" argument will split the windows horizontally;

the "-O" argument will split the windows vertically. If both "-o" and "-O"

are given, the last one encountered will be used to determine the split

orientation. For example, this will open three windows, split horizontally:

vim -o file1 file2 file3

"-oN", where N is a decimal number, opens N windows split horizontally. If

there are more file names than windows, only N windows are opened and some

files do not get a window. If there are more windows than file names, the

last few windows will be editing empty buffers. Similarly, "-ON" opens N

windows split vertically, with the same restrictions.

If there are many file names, the windows will become very small. You might

want to set the 'winheight' and/or 'winwidth' options to create a workable

situation.

Buf/Win Enter/Leave autocommands are not executed when opening the new

windows and reading the files, that's only done when they are really entered.

status-lineLINK

A status line will be used to separate windows. The 'laststatus' option tells

when the last window also has a status line:

'laststatus' = 0 never a status line

'laststatus' = 1 status line if there is more than one window

'laststatus' = 2 always a status line

You can change the contents of the status line with the 'statusline' option.

This option can be local to the window, so that you can have a different

status line in each window.

Normally, inversion is used to display the status line. This can be changed

with the 's' character in the 'highlight' option. For example, "sb" sets it to

bold characters. If no highlighting is used for the status line ("sn"), the

'^' character is used for the current window, and '=' for other windows. If

the mouse is supported and enabled with the 'mouse' option, a status line can

be dragged to resize windows.

Note: If you expect your status line to be in reverse video and it isn't,

check if the 'highlight' option contains "si". In version 3.0, this meant to

invert the status line. Now it should be "sr", reverse the status line, as

"si" now stands for italic! If italic is not available on your terminal, the

status line is inverted anyway; you will only see this problem on terminals

that have termcap codes for italics.

==============================================================================

3. Opening and closing a window opening-window E36LINK

CTRL-W s CTRL-W_sLINK

CTRL-W S CTRL-W_SLINK

CTRL-W CTRL-S CTRL-W_CTRL-SLINK

:[N]sp[lit] [++opt] [+cmd] [file] :sp :splitLINK

Split current window in two. The result is two viewports on

the same file.

Make the new window N high (default is to use half the height

of the current window). Reduces the current window height to

create room (and others, if the 'equalalways' option is set,

'eadirection' isn't "hor", and one of them is higher than the

current or the new window).

If [file] is given it will be edited in the new window. If it

is not loaded in any buffer, it will be read. Else the new

window will use the already loaded buffer.

Note: CTRL-S does not work on all terminals and might block

further input, use CTRL-Q to get going again.

Also see ++opt and +cmd.

CTRL-W CTRL-V CTRL-W_CTRL-VLINK

CTRL-W v CTRL-W_vLINK

:[N]vs[plit] [++opt] [+cmd] [file] :vs :vsplitLINK

Like :split, but split vertically. The windows will be

spread out horizontally if

1. a width was not specified,

2. 'equalalways' is set,

3. 'eadirection' isn't "ver", and

4. one of the other windows is wider than the current or new

window.

Note: In other places CTRL-Q does the same as CTRL-V, but here

it doesn't!

CTRL-W n CTRL-W_nLINK

CTRL-W CTRL_N CTRL-W_CTRL-NLINK

:[N]new [++opt] [+cmd] :newLINK

Create a new window and start editing an empty file in it.

Make new window N high (default is to use half the existing

height). Reduces the current window height to create room (and

others, if the 'equalalways' option is set and 'eadirection'

isn't "hor").

Also see ++opt and +cmd.

If 'fileformats' is not empty, the first format given will be

used for the new buffer. If 'fileformats' is empty, the

'fileformat' of the current buffer is used. This can be

overridden with the ++opt argument.

Autocommands are executed in this order:

1. WinLeave for the current window

2. WinEnter for the new window

3. BufLeave for the current buffer

4. BufEnter for the new buffer

This behaves like a ":split" first, and then an ":enew"

command.

:[N]vne[w] [++opt] [+cmd] [file] :vne :vnewLINK

Like :new, but split vertically. If 'equalalways' is set

and 'eadirection' isn't "ver" the windows will be spread out

horizontally, unless a width was specified.

:[N]new [++opt] [+cmd] {file}

:[N]sp[lit] [++opt] [+cmd] {file} :split_fLINK

Create a new window and start editing file {file} in it. This

behaves like a ":split" first, and then an ":e" command.

If [+cmd] is given, execute the command when the file has been

loaded +cmd.

Also see ++opt.

Make new window N high (default is to use half the existing

height). Reduces the current window height to create room

(and others, if the 'equalalways' option is set).

:[N]sv[iew] [++opt] [+cmd] {file} :sv :sview splitviewLINK

Same as ":split", but set 'readonly' option for this buffer.

:[N]sf[ind] [++opt] [+cmd] {file} :sf :sfind splitfindLINK

Same as ":split", but search for {file} in 'path' like in

:find. Doesn't split if {file} is not found.

CTRL-W CTRL-^ CTRL-W_CTRL-^ CTRL-W_^LINK

CTRL-W ^ Does ":split #", split window in two and edit alternate file.

When a count is given, it becomes ":split #N", split window

and edit buffer N.

Note that the 'splitbelow' and 'splitright' options influence where a new

window will appear.

:vert :verticalLINK

:vert[ical] {cmd}

Execute {cmd}. If it contains a command that splits a window,

it will be split vertically.

Doesn't work for :execute and :normal.

:lefta[bove] {cmd} :lefta :leftaboveLINK

:abo[veleft] {cmd} :abo :aboveleftLINK

Execute {cmd}. If it contains a command that splits a window,

it will be opened left (vertical split) or above (horizontal

split) the current window. Overrules 'splitbelow' and

'splitright'.

Doesn't work for :execute and :normal.

:rightb[elow] {cmd} :rightb :rightbelowLINK

:bel[owright] {cmd} :bel :belowrightLINK

Execute {cmd}. If it contains a command that splits a window,

it will be opened right (vertical split) or below (horizontal

split) the current window. Overrules 'splitbelow' and

'splitright'.

Doesn't work for :execute and :normal.

:topleft E442LINK

:to[pleft] {cmd}

Execute {cmd}. If it contains a command that splits a window,

it will appear at the top and occupy the full width of the Vim

window. When the split is vertical the window appears at the

far left and occupies the full height of the Vim window.

Doesn't work for :execute and :normal.

:botrightLINK

:bo[tright] {cmd}

Execute {cmd}. If it contains a command that splits a window,

it will appear at the bottom and occupy the full width of the

Vim window. When the split is vertical the window appears at

the far right and occupies the full height of the Vim window.

Doesn't work for :execute and :normal.

These command modifiers can be combined to make a vertically split window

occupy the full height. Example:

:vertical topleft split tags

Opens a vertically split, full-height window on the "tags" file at the far

left of the Vim window.

Closing a window

----------------

:q[uit]

:{count}q[uit]

CTRL-W q CTRL-W_qLINK

CTRL-W CTRL-Q CTRL-W_CTRL-QLINK

Without {count}: Quit the current window. If {count} is

given quit the {count} window.

When quitting the last window (not counting a help window),

exit Vim.

When 'hidden' is set, and there is only one window for the

current buffer, it becomes hidden. When 'hidden' is not set,

and there is only one window for the current buffer, and the

buffer was changed, the command fails.

(Note: CTRL-Q does not work on all terminals).

If [count] is greater than the last window number the last

window will be closed:

:1quit " quit the first window

:$quit " quit the last window

:9quit " quit the last window

" if there are less than 9 windows opened

:-quit " quit the previews window

:+quit " quit the next window

:+2quit " quit the second next window

:q[uit]!

:{count}q[uit]!

Without {count}: Quit the current window. If {count} is

given quit the {count} window.

If this was the last window for a buffer, any changes to that

buffer are lost. When quitting the last window (not counting

help windows), exit Vim. The contents of the buffer are lost,

even when 'hidden' is set.

:clo[se][!]

:{count}clo[se][!]

CTRL-W c CTRL-W_c :clo :closeLINK

Without {count}: Close the current window. If {count} is

given close the {count} window.

When the 'hidden' option is set, or when the buffer was

changed and the [!] is used, the buffer becomes hidden (unless

there is another window editing it).

When there is only one window in the current tab page and

there is another tab page, this closes the current tab page.

tab-page.

This command fails when: E444LINK

- There is only one window on the screen.

- When 'hidden' is not set, [!] is not used, the buffer has

changes, and there is no other window on this buffer.

Changes to the buffer are not written and won't get lost, so

this is a "safe" command.

CTRL-W CTRL-C CTRL-W_CTRL-CLINK

You might have expected that CTRL-W CTRL-C closes the current

window, but that does not work, because the CTRL-C cancels the

command.

:hideLINK

:hid[e]

:{count}hid[e]

Quit the current window, unless it is the last window on the

screen. For {count} see :quit command.

The buffer becomes hidden (unless there is another window

editing it or 'bufhidden' is "unload", "delete" or "wipe").

If the window is the last one in the current tab page the tab

page is closed. tab-page

The value of 'hidden' is irrelevant for this command. Changes

to the buffer are not written and won't get lost, so this is a

"safe" command.

:hid[e] {cmd} Execute {cmd} with 'hidden' is set. The previous value of

'hidden' is restored after {cmd} has been executed.

Example:

:hide edit Makefile

This will edit "Makefile", and hide the current buffer if it

has any changes.

:on[ly][!]

:{count}on[ly][!]

CTRL-W o CTRL-W_o E445LINK

CTRL-W CTRL-O CTRL-W_CTRL-O :on :onlyLINK

Make the current window the only one on the screen. All other

windows are closed. For {count} see :quit command.

When the 'hidden' option is set, all buffers in closed windows

become hidden.

When 'hidden' is not set, and the 'autowrite' option is set,

modified buffers are written. Otherwise, windows that have

buffers that are modified are not removed, unless the [!] is

given, then they become hidden. But modified buffers are

never abandoned, so changes cannot get lost.

==============================================================================

4. Moving cursor to other windows window-move-cursorLINK

CTRL-W <Down> CTRL-W_<Down>LINK

CTRL-W CTRL-J CTRL-W_CTRL-J CTRL-W_jLINK

CTRL-W j Move cursor to Nth window below current one. Uses the cursor

position to select between alternatives.

CTRL-W <Up> CTRL-W_<Up>LINK

CTRL-W CTRL-K CTRL-W_CTRL-K CTRL-W_kLINK

CTRL-W k Move cursor to Nth window above current one. Uses the cursor

position to select between alternatives.

CTRL-W <Left> CTRL-W_<Left>LINK

CTRL-W CTRL-H CTRL-W_CTRL-HLINK

CTRL-W <BS> CTRL-W_<BS> CTRL-W_hLINK

CTRL-W h Move cursor to Nth window left of current one. Uses the

cursor position to select between alternatives.

CTRL-W <Right> CTRL-W_<Right>LINK

CTRL-W CTRL-L CTRL-W_CTRL-L CTRL-W_lLINK

CTRL-W l Move cursor to Nth window right of current one. Uses the

cursor position to select between alternatives.

CTRL-W w CTRL-W_w CTRL-W_CTRL-WLINK

CTRL-W CTRL-W Without count: move cursor to window below/right of the

current one. If there is no window below or right, go to

top-left window.

With count: go to Nth window (windows are numbered from

top-left to bottom-right). To obtain the window number see

bufwinnr() and winnr(). When N is larger than the number

of windows go to the last window.

CTRL-W_WLINK

CTRL-W W Without count: move cursor to window above/left of current

one. If there is no window above or left, go to bottom-right

window. With count: go to Nth window, like with CTRL-W w.

CTRL-W t CTRL-W_t CTRL-W_CTRL-TLINK

CTRL-W CTRL-T Move cursor to top-left window.

CTRL-W b CTRL-W_b CTRL-W_CTRL-BLINK

CTRL-W CTRL-B Move cursor to bottom-right window.

CTRL-W p CTRL-W_p CTRL-W_CTRL-PLINK

CTRL-W CTRL-P Go to previous (last accessed) window.

CTRL-W_P E441LINK

CTRL-W P Go to preview window. When there is no preview window this is

an error.

{not available when compiled without the +quickfix feature}

If Visual mode is active and the new window is not for the same buffer, the

Visual mode is ended. If the window is on the same buffer, the cursor

position is set to keep the same Visual area selected.

:winc :wincmdLINK

These commands can also be executed with ":wincmd":

:[count]winc[md] {arg}

Like executing CTRL-W [count] {arg}. Example:

:wincmd j

Moves to the window below the current one.

This command is useful when a Normal mode cannot be used (for

the CursorHold autocommand event). Or when a Normal mode

command is inconvenient.

The count can also be a window number. Example:

:exe nr . "wincmd w"

This goes to window "nr".

==============================================================================

5. Moving windows around window-movingLINK

CTRL-W r CTRL-W_r CTRL-W_CTRL-R E443LINK

CTRL-W CTRL-R Rotate windows downwards/rightwards. The first window becomes

the second one, the second one becomes the third one, etc.

The last window becomes the first window. The cursor remains

in the same window.

This only works within the row or column of windows that the

current window is in.

CTRL-W_RLINK

CTRL-W R Rotate windows upwards/leftwards. The second window becomes

the first one, the third one becomes the second one, etc. The

first window becomes the last window. The cursor remains in

the same window.

This only works within the row or column of windows that the

current window is in.

CTRL-W x CTRL-W_x CTRL-W_CTRL-XLINK

CTRL-W CTRL-X Without count: Exchange current window with next one. If there

is no next window, exchange with previous window.

With count: Exchange current window with Nth window (first

window is 1). The cursor is put in the other window.

When vertical and horizontal window splits are mixed, the

exchange is only done in the row or column of windows that the

current window is in.

The following commands can be used to change the window layout. For example,

when there are two vertically split windows, CTRL-W K will change that in

horizontally split windows. CTRL-W H does it the other way around.

CTRL-W_KLINK

CTRL-W K Move the current window to be at the very top, using the full

width of the screen. This works like closing the current

window and then creating another one with ":topleft split",

except that the current window contents is used for the new

window.

CTRL-W_JLINK

CTRL-W J Move the current window to be at the very bottom, using the

full width of the screen. This works like closing the current

window and then creating another one with ":botright split",

except that the current window contents is used for the new

window.

CTRL-W_HLINK

CTRL-W H Move the current window to be at the far left, using the

full height of the screen. This works like closing the

current window and then creating another one with

":vert topleft split", except that the current window contents

is used for the new window.

{not available when compiled without the +vertsplit feature}

CTRL-W_LLINK

CTRL-W L Move the current window to be at the far right, using the full

height of the screen. This works like closing the

current window and then creating another one with

":vert botright split", except that the current window

contents is used for the new window.

{not available when compiled without the +vertsplit feature}

CTRL-W_TLINK

CTRL-W T Move the current window to a new tab page. This fails if

there is only one window in the current tab page.

When a count is specified the new tab page will be opened

before the tab page with this index. Otherwise it comes after

the current tab page.

==============================================================================

6. Window resizing window-resizeLINK

CTRL-W_=LINK

CTRL-W = Make all windows (almost) equally high and wide, but use

'winheight' and 'winwidth' for the current window.

Windows with 'winfixheight' set keep their height and windows

with 'winfixwidth' set keep their width.

:res[ize] -N :res :resize CTRL-W_-LINK

CTRL-W - Decrease current window height by N (default 1).

If used after :vertical: decrease width by N.

:res[ize] +N CTRL-W_+LINK

CTRL-W + Increase current window height by N (default 1).

If used after :vertical: increase width by N.

:res[ize] [N]

CTRL-W CTRL-_ CTRL-W_CTRL-_ CTRL-W__LINK

CTRL-W _ Set current window height to N (default: highest possible).

z{nr}<CR> Set current window height to {nr}.

CTRL-W_<LINK

CTRL-W < Decrease current window width by N (default 1).

CTRL-W_>LINK

CTRL-W > Increase current window width by N (default 1).

:vertical res[ize] [N] :vertical-resize CTRL-W_barLINK

CTRL-W | Set current window width to N (default: widest possible).

You can also resize a window by dragging a status line up or down with the

mouse. Or by dragging a vertical separator line left or right. This only

works if the version of Vim that is being used supports the mouse and the

'mouse' option has been set to enable it.

The option 'winheight' ('wh') is used to set the minimal window height of the

current window. This option is used each time another window becomes the

current window. If the option is '0', it is disabled. Set 'winheight' to a

very large value, e.g., '9999', to make the current window always fill all

available space. Set it to a reasonable value, e.g., '10', to make editing in

the current window comfortable.

The equivalent 'winwidth' ('wiw') option is used to set the minimal width of

the current window.

When the option 'equalalways' ('ea') is set, all the windows are automatically

made the same size after splitting or closing a window. If you don't set this

option, splitting a window will reduce the size of the current window and

leave the other windows the same. When closing a window, the extra lines are

given to the window above it.

The 'eadirection' option limits the direction in which the 'equalalways'

option is applied. The default "both" resizes in both directions. When the

value is "ver" only the heights of windows are equalized. Use this when you

have manually resized a vertically split window and want to keep this width.

Likewise, "hor" causes only the widths of windows to be equalized.

The option 'cmdheight' ('ch') is used to set the height of the command-line.

If you are annoyed by the hit-enter prompt for long messages, set this

option to 2 or 3.

If there is only one window, resizing that window will also change the command

line height. If there are several windows, resizing the current window will

also change the height of the window below it (and sometimes the window above

it).

The minimal height and width of a window is set with 'winminheight' and

'winminwidth'. These are hard values, a window will never become smaller.

7. Argument and buffer list commands buffer-listLINK

args list buffer list meaning

1. :[N]argument [N] 11. :[N]buffer [N] to arg/buf N

2. :[N]next [file ..] 12. :[N]bnext [N] to Nth next arg/buf

3. :[N]Next [N] 13. :[N]bNext [N] to Nth previous arg/buf

6. :last 16. :blast to last arg/buf

7. :all 17. :ball edit all args/buffers

18. :unhide edit all loaded buffers

19. :[N]bmod [N] to Nth modified buf

split & args list split & buffer list meaning

21. :[N]sargument [N] 31. :[N]sbuffer [N] split + to arg/buf N

22. :[N]snext [file ..] 32. :[N]sbnext [N] split + to Nth next arg/buf

23. :[N]sNext [N] 33. :[N]sbNext [N] split + to Nth previous arg/buf

24. :[N]sprevious [N] 34. :[N]sbprevious [N] split + to Nth previous arg/buf

25. :srewind / :sfirst 35. :sbrewind / :sbfirst split + to first arg/buf

26. :slast 36. :sblast split + to last arg/buf

27. :sall 37. :sball edit all args/buffers

38. :sunhide edit all loaded buffers

39. :[N]sbmod [N] split + to Nth modified buf

40. :args list of arguments

41. :buffers list of buffers

The meaning of [N] depends on the command:

[N] is number of buffers to go forward/backward on ?2, ?3, and ?4

[N] is an argument number, defaulting to current argument, for 1 and 21

[N] is a buffer number, defaulting to current buffer, for 11 and 31

[N] is a count for 19 and 39

Note: ":next" is an exception, because it must accept a list of file names

for compatibility with Vi.

The argument list and multiple windows

--------------------------------------

The current position in the argument list can be different for each window.

Remember that when doing ":e file", the position in the argument list stays

the same, but you are not editing the file at that position. To indicate

this, the file message (and the title, if you have one) shows

"(file (N) of M)", where "(N)" is the current position in the file list, and

"M" the number of files in the file list.

All the entries in the argument list are added to the buffer list. Thus, you

can also get to them with the buffer list commands, like ":bnext".

:[N]al[l][!] [N] :al :all :sal :sallLINK

:[N]sal[l][!] [N]

Rearrange the screen to open one window for each argument.

All other windows are closed. When a count is given, this is

the maximum number of windows to open.

With the :tab modifier open a tab page for each argument.

When there are more arguments than 'tabpagemax' further ones

become split windows in the last tab page.

When the 'hidden' option is set, all buffers in closed windows

become hidden.

When 'hidden' is not set, and the 'autowrite' option is set,

modified buffers are written. Otherwise, windows that have

buffers that are modified are not removed, unless the [!] is

given, then they become hidden. But modified buffers are

never abandoned, so changes cannot get lost.

[N] is the maximum number of windows to open. 'winheight'

also limits the number of windows opened ('winwidth' if

:vertical was prepended).

Buf/Win Enter/Leave autocommands are not executed for the new

windows here, that's only done when they are really entered.

:[N]sa[rgument][!] [++opt] [+cmd] [N] :sa :sargumentLINK

Short for ":split | argument [N]": split window and go to Nth

argument. But when there is no such argument, the window is

not split. Also see ++opt and +cmd.

:[N]sn[ext][!] [++opt] [+cmd] [file ..] :sn :snextLINK

Short for ":split | [N]next": split window and go to Nth next

argument. But when there is no next file, the window is not

split. Also see ++opt and +cmd.

:[N]spr[evious][!] [++opt] [+cmd] [N] :spr :spreviousLINK

:[N]sN[ext][!] [++opt] [+cmd] [N] :sN :sNextLINK

Short for ":split | [N]Next": split window and go to Nth

previous argument. But when there is no previous file, the

window is not split. Also see ++opt and +cmd.

:sre :srewindLINK

:sre[wind][!] [++opt] [+cmd]

Short for ":split | rewind": split window and go to first

argument. But when there is no argument list, the window is

not split. Also see ++opt and +cmd.

:sfir :sfirstLINK

:sfir[st] [++opt] [+cmd]

Same as ":srewind".

:sla :slastLINK

:sla[st][!] [++opt] [+cmd]

Short for ":split | last": split window and go to last

argument. But when there is no argument list, the window is

not split. Also see ++opt and +cmd.

:dr :dropLINK

:dr[op] [++opt] [+cmd] {file} ..

Edit the first {file} in a window.

- If the file is already open in a window change to that

window.

- If the file is not open in a window edit the file in the

current window. If the current buffer can't be abandoned,

the window is split first.

The argument-list is set, like with the :next command.

The purpose of this command is that it can be used from a

program that wants Vim to edit another file, e.g., a debugger.

When using the :tab modifier each argument is opened in a

tab page. The last window is used if it's empty.

8. Do a command in all buffers or windows list-repeatLINK

:windoLINK

:windo {cmd} Execute {cmd} in each window.

It works like doing this:

CTRL-W t

:{cmd}

CTRL-W w

:{cmd}

etc.

This only operates in the current tab page.

When an error is detected on one window, further

windows will not be visited.

The last window (or where an error occurred) becomes

the current window.

{cmd} can contain '|' to concatenate several commands.

{cmd} must not open or close windows or reorder them.

{not in Vi} {not available when compiled without the

+listcmds feature}

Also see :tabdo, :argdo and :bufdo.

:bufdoLINK

:bufdo[!] {cmd} Execute {cmd} in each buffer in the buffer list.

It works like doing this:

:bfirst

:{cmd}

:bnext

:{cmd}

etc.

When the current file can't be abandoned and the [!]

is not present, the command fails.

When an error is detected on one buffer, further

buffers will not be visited.

Unlisted buffers are skipped.

The last buffer (or where an error occurred) becomes

the current buffer.

{cmd} can contain '|' to concatenate several commands.

{cmd} must not delete buffers or add buffers to the

buffer list.

Note: While this command is executing, the Syntax

autocommand event is disabled by adding it to

'eventignore'. This considerably speeds up editing

each buffer.

{not in Vi} {not available when compiled without the

+listcmds feature}

Also see :tabdo, :argdo and :windo.

Examples:

:windo set nolist nofoldcolumn | normal zn

This resets the 'list' option and disables folding in all windows.

:bufdo set fileencoding= | update

This resets the 'fileencoding' in each buffer and writes it if this changed

the buffer. The result is that all buffers will use the 'encoding' encoding

(if conversion works properly).

==============================================================================

9. Tag or file name under the cursor window-tagLINK

:sta :stagLINK

:sta[g][!] [tagname]

Does ":tag[!] [tagname]" and splits the window for the found

tag. See also :tag.

CTRL-W ] CTRL-W_] CTRL-W_CTRL-]LINK

CTRL-W CTRL-] Split current window in two. Use identifier under cursor as a

tag and jump to it in the new upper window.

In Visual mode uses the Visually selected text as a tag.

Make new window N high.

CTRL-W_g]LINK

CTRL-W g ] Split current window in two. Use identifier under cursor as a

tag and perform ":tselect" on it in the new upper window.

In Visual mode uses the Visually selected text as a tag.

Make new window N high.

CTRL-W_g_CTRL-]LINK

CTRL-W g CTRL-] Split current window in two. Use identifier under cursor as a

tag and perform ":tjump" on it in the new upper window.

In Visual mode uses the Visually selected text as a tag.

Make new window N high.

CTRL-W f CTRL-W_f CTRL-W_CTRL-FLINK

CTRL-W CTRL-F Split current window in two. Edit file name under cursor.

Like ":split gf", but window isn't split if the file does not

exist.

Uses the 'path' variable as a list of directory names where to

look for the file. Also the path for current file is

used to search for the file name.

If the name is a hypertext link that looks like

"type://machine/path", only "/path" is used.

If a count is given, the count'th matching file is edited.

{not available when the +file_in_path feature was disabled

at compile time}

CTRL-W F CTRL-W_FLINK

Split current window in two. Edit file name under cursor and

jump to the line number following the file name. See gF for

details on how the line number is obtained.

{not available when the +file_in_path feature was disabled

at compile time}

CTRL-W gf CTRL-W_gfLINK

Open a new tab page and edit the file name under the cursor.

Like "tab split" and "gf", but the new tab page isn't created

if the file does not exist.

{not available when the +file_in_path feature was disabled

at compile time}

CTRL-W gF CTRL-W_gFLINK

Open a new tab page and edit the file name under the cursor

and jump to the line number following the file name. Like

"tab split" and "gF", but the new tab page isn't created if

the file does not exist.

{not available when the +file_in_path feature was disabled

at compile time}

Also see CTRL-W_CTRL-I: open window for an included file that includes

the keyword under the cursor.

==============================================================================

10. The preview window preview-windowLINK

The preview window is a special window to show (preview) another file. It is

normally a small window used to show an include file or definition of a

function.

{not available when compiled without the +quickfix feature}

There can be only one preview window (per tab page). It is created with one

of the commands below. The 'previewheight' option can be set to specify the

height of the preview window when it's opened. The 'previewwindow' option is

set in the preview window to be able to recognize it. The 'winfixheight'

option is set to have it keep the same height when opening/closing other

windows.

:pta :ptagLINK

:pta[g][!] [tagname]

Does ":tag[!] [tagname]" and shows the found tag in a

"Preview" window without changing the current buffer or cursor

position. If a "Preview" window already exists, it is re-used

(like a help window is). If a new one is opened,

'previewheight' is used for the height of the window. See

also :tag.

See below for an example. CursorHold-example

Small difference from :tag: When [tagname] is equal to the

already displayed tag, the position in the matching tag list

is not reset. This makes the CursorHold example work after a

:ptnext.

CTRL-W z CTRL-W_zLINK

CTRL-W CTRL-Z CTRL-W_CTRL-Z :pc :pcloseLINK

:pc[lose][!] Close any "Preview" window currently open. When the 'hidden'

option is set, or when the buffer was changed and the [!] is

used, the buffer becomes hidden (unless there is another

window editing it). The command fails if any "Preview" buffer

cannot be closed. See also :close.

:pp :ppopLINK

:[count]pp[op][!]

Does ":[count]pop[!]" in the preview window. See :pop and

:ptag. {not in Vi}

CTRL-W } CTRL-W_}LINK

Use identifier under cursor as a tag and perform a :ptag on

it. Make the new Preview window (if required) N high. If N is

not given, 'previewheight' is used.

CTRL-W g } CTRL-W_g}LINK

Use identifier under cursor as a tag and perform a :ptjump on

it. Make the new Preview window (if required) N high. If N is

not given, 'previewheight' is used.

:ped :peditLINK

:ped[it][!] [++opt] [+cmd] {file}

Edit {file} in the preview window. The preview window is

opened like with :ptag. The current window and cursor

position isn't changed. Useful example:

:pedit +/fputc /usr/include/stdio.h

:ps :psearchLINK

:[range]ps[earch][!] [count] [/]pattern[/]

Works like :ijump but shows the found match in the preview

window. The preview window is opened like with :ptag. The

current window and cursor position isn't changed. Useful

example:

:psearch popen

Like with the :ptag command, you can use this to

automatically show information about the word under the

cursor. This is less clever than using :ptag, but you don't

need a tags file and it will also find matches in system

include files. Example:

:au! CursorHold *.[ch] nested exe "silent! psearch " . expand("<cword>")

Warning: This can be slow.

Example CursorHold-example LINK

:au! CursorHold *.[ch] nested exe "silent! ptag " . expand("<cword>")

This will cause a ":ptag" to be executed for the keyword under the cursor,

when the cursor hasn't moved for the time set with 'updatetime'. The "nested"

makes other autocommands be executed, so that syntax highlighting works in the

preview window. The "silent!" avoids an error message when the tag could not

be found. Also see CursorHold. To disable this again:

:au! CursorHold

A nice addition is to highlight the found tag, avoid the ":ptag" when there

is no word under the cursor, and a few other things:

:au! CursorHold *.[ch] nested call PreviewWord()

:func PreviewWord()

: if &previewwindow " don't do this in the preview window

: return

: endif

: let w = expand("<cword>") " get the word under cursor

: if w =~ '\a' " if the word contains a letter

:

: " Delete any existing highlight before showing another tag

: silent! wincmd P " jump to preview window

: if &previewwindow " if we really get there...

: match none " delete existing highlight

: wincmd p " back to old window

: endif

:

: " Try displaying a matching tag for the word under the cursor

: try

: exe "ptag " . w

: catch

: return

: endtry

:

: silent! wincmd P " jump to preview window

: if &previewwindow " if we really get there...

: if has("folding")

: silent! .foldopen " don't want a closed fold

: endif

: call search("$", "b") " to end of previous line

: let w = substitute(w, '\\', '\\\\', "")

: call search('\<\V' . w . '\>') " position cursor on match

: " Add a match highlight to the word at this position

: hi previewWord term=bold ctermbg=green guibg=green

: exe 'match previewWord "\%' . line(".") . 'l\%' . col(".") . 'c\k*"'

: wincmd p " back to old window

: endif

: endif

:endfun

==============================================================================

11. Using hidden buffers buffer-hiddenLINK

A hidden buffer is not displayed in a window, but is still loaded into memory.

This makes it possible to jump from file to file, without the need to read or

write the file every time you get another buffer in a window.

{not available when compiled without the +listcmds feature}

:buffer-!LINK

If the option 'hidden' ('hid') is set, abandoned buffers are kept for all

commands that start editing another file: ":edit", ":next", ":tag", etc. The

commands that move through the buffer list sometimes make the current buffer

hidden although the 'hidden' option is not set. This happens when a buffer is

modified, but is forced (with '!') to be removed from a window, and

'autowrite' is off or the buffer can't be written.

You can make a hidden buffer not hidden by starting to edit it with any

command. Or by deleting it with the ":bdelete" command.

The 'hidden' is global, it is used for all buffers. The 'bufhidden' option

can be used to make an exception for a specific buffer. It can take these

values:

<empty> Use the value of 'hidden'.

hide Hide this buffer, also when 'hidden' is not set.

unload Don't hide but unload this buffer, also when 'hidden'

is set.

delete Delete the buffer.

hidden-quitLINK

When you try to quit Vim while there is a hidden, modified buffer, you will

get an error message and Vim will make that buffer the current buffer. You

can then decide to write this buffer (":wq") or quit without writing (":q!").

Be careful: there may be more hidden, modified buffers!

A buffer can also be unlisted. This means it exists, but it is not in the

list of buffers. unlisted-buffer

:files[!] :filesLINK

:buffers[!] :buffers :lsLINK

:ls[!] Show all buffers. Example:

1 #h "/test/text" line 1

2u "asdf" line 0

3 %a + "version.c" line 1

When the [!] is included the list will show unlisted buffers

(the term "unlisted" is a bit confusing then...).

Each buffer has a unique number. That number will not change,

so you can always go to a specific buffer with ":buffer N" or

"N CTRL-^", where N is the buffer number.

Indicators (chars in the same column are mutually exclusive):

u an unlisted buffer (only displayed when [!] is used)

unlisted-buffer

% the buffer in the current window

# the alternate buffer for ":e #" and CTRL-^

a an active buffer: it is loaded and visible

h a hidden buffer: It is loaded, but currently not

displayed in a window hidden-buffer

- a buffer with 'modifiable' off

= a readonly buffer

+ a modified buffer

x a buffer with read errors

:bad :baddLINK

:bad[d] [+lnum] {fname}

Add file name {fname} to the buffer list, without loading it.

If "lnum" is specified, the cursor will be positioned at that

line when the buffer is first entered. Note that other

commands after the + will be ignored.

:[N]bd[elete][!] :bd :bdel :bdelete E516LINK

:bd[elete][!] [N]

Unload buffer [N] (default: current buffer) and delete it from

the buffer list. If the buffer was changed, this fails,

unless when [!] is specified, in which case changes are lost.

The file remains unaffected. Any windows for this buffer are

closed. If buffer [N] is the current buffer, another buffer

will be displayed instead. This is the most recent entry in

the jump list that points into a loaded buffer.

Actually, the buffer isn't completely deleted, it is removed

from the buffer list unlisted-buffer and option values,

variables and mappings/abbreviations for the buffer are

cleared. Examples:

:.,$-bdelete " delete buffers from the current one to

" last but one

:%bdelete " delete all buffers

:bdelete[!] {bufname} E93 E94LINK

Like ":bdelete[!] [N]", but buffer given by name. Note that a

buffer whose name is a number cannot be referenced by that

name; use the buffer number instead. Insert a backslash

before a space in a buffer name.

:bdelete[!] N1 N2 ...

Do ":bdelete[!]" for buffer N1, N2, etc. The arguments can be

buffer numbers or buffer names (but not buffer names that are

a number). Insert a backslash before a space in a buffer

name.

:N,Mbdelete[!] Do ":bdelete[!]" for all buffers in the range N to M

inclusive.

:[N]bw[ipeout][!] :bw :bwipe :bwipeout E517LINK

:bw[ipeout][!] {bufname}

:N,Mbw[ipeout][!]

:bw[ipeout][!] N1 N2 ...

Like :bdelete, but really delete the buffer. Everything

related to the buffer is lost. All marks in this buffer

become invalid, option settings are lost, etc. Don't use this

unless you know what you are doing. Examples:

:.+,$bwipeout " wipe out all buffers after the current

" one

:%bwipeout " wipe out all buffers

:[N]bun[load][!] :bun :bunload E515LINK

:bun[load][!] [N]

Unload buffer [N] (default: current buffer). The memory

allocated for this buffer will be freed. The buffer remains

in the buffer list.

If the buffer was changed, this fails, unless when [!] is

specified, in which case the changes are lost.

Any windows for this buffer are closed. If buffer [N] is the

current buffer, another buffer will be displayed instead.

This is the most recent entry in the jump list that points

into a loaded buffer.

:bunload[!] {bufname}

Like ":bunload[!] [N]", but buffer given by name. Note that a

buffer whose name is a number cannot be referenced by that

name; use the buffer number instead. Insert a backslash

before a space in a buffer name.

:N,Mbunload[!] Do ":bunload[!]" for all buffers in the range N to M

inclusive.

:bunload[!] N1 N2 ...

Do ":bunload[!]" for buffer N1, N2, etc. The arguments can be

buffer numbers or buffer names (but not buffer names that are

a number). Insert a backslash before a space in a buffer

name.

:[N]b[uffer][!] [+cmd] [N] :b :bu :buf :buffer E86LINK

Edit buffer [N] from the buffer list. If [N] is not given,

the current buffer remains being edited. See :buffer-! for

[!]. This will also edit a buffer that is not in the buffer

list, without setting the 'buflisted' flag.

Also see +cmd.

:[N]b[uffer][!] [+cmd] {bufname}

Edit buffer for {bufname} from the buffer list. See

:buffer-! for [!]. This will also edit a buffer that is not

in the buffer list, without setting the 'buflisted' flag.

Also see +cmd.

:[N]sb[uffer] [+cmd] [N] :sb :sbufferLINK

Split window and edit buffer [N] from the buffer list. If [N]

is not given, the current buffer is edited. Respects the

"useopen" setting of 'switchbuf' when splitting. This will

also edit a buffer that is not in the buffer list, without

setting the 'buflisted' flag.

Also see +cmd.

:[N]sb[uffer] [+cmd] {bufname}

Split window and edit buffer for {bufname} from the buffer

list. This will also edit a buffer that is not in the buffer

list, without setting the 'buflisted' flag.

Note: If what you want to do is split the buffer, make a copy

under another name, you can do it this way:

:w foobar | sp #

Also see +cmd.

:[N]bn[ext][!] [+cmd] [N] :bn :bnext E87LINK

Go to [N]th next buffer in buffer list. [N] defaults to one.

Wraps around the end of the buffer list.

See :buffer-! for [!].

Also see +cmd.

If you are in a help buffer, this takes you to the next help

buffer (if there is one). Similarly, if you are in a normal

(non-help) buffer, this takes you to the next normal buffer.

This is so that if you have invoked help, it doesn't get in

the way when you're browsing code/text buffers. The next three

commands also work like this.

:sbn :sbnextLINK

:[N]sbn[ext] [+cmd] [N]

Split window and go to [N]th next buffer in buffer list.

Wraps around the end of the buffer list. Uses 'switchbuf'

Also see +cmd.

:[N]bN[ext][!] [+cmd] [N] :bN :bNext :bp :bprevious E88LINK

:[N]bp[revious][!] [+cmd] [N]

Go to [N]th previous buffer in buffer list. [N] defaults to

one. Wraps around the start of the buffer list.

See :buffer-! for [!] and 'switchbuf'.

Also see +cmd.

:[N]sbN[ext] [+cmd] [N] :sbN :sbNext :sbp :sbpreviousLINK

:[N]sbp[revious] [+cmd] [N]

Split window and go to [N]th previous buffer in buffer list.

Wraps around the start of the buffer list.

Uses 'switchbuf'.

Also see +cmd.

:br[ewind][!] [+cmd] :br :brewindLINK

Go to first buffer in buffer list. If the buffer list is

empty, go to the first unlisted buffer.

See :buffer-! for [!].

:bf[irst] [+cmd] :bf :bfirstLINK

Same as :brewind.

Also see +cmd.

:sbr[ewind] [+cmd] :sbr :sbrewindLINK

Split window and go to first buffer in buffer list. If the

buffer list is empty, go to the first unlisted buffer.

Respects the 'switchbuf' option.

Also see +cmd.

:sbf[irst] [+cmd] :sbf :sbfirstLINK

Same as ":sbrewind".

:bl[ast][!] [+cmd] :bl :blastLINK

Go to last buffer in buffer list. If the buffer list is

empty, go to the last unlisted buffer.

See :buffer-! for [!].

:sbl[ast] [+cmd] :sbl :sblastLINK

Split window and go to last buffer in buffer list. If the

buffer list is empty, go to the last unlisted buffer.

Respects 'switchbuf' option.

:[N]bm[odified][!] [+cmd] [N] :bm :bmodified E84LINK

Go to [N]th next modified buffer. Note: this command also

finds unlisted buffers. If there is no modified buffer the

command fails.

:[N]sbm[odified] [+cmd] [N] :sbm :sbmodifiedLINK

Split window and go to [N]th next modified buffer.

Respects 'switchbuf' option.

Note: this command also finds buffers not in the buffer list.

:[N]unh[ide] [N] :unh :unhide :sun :sunhideLINK

:[N]sun[hide] [N]

Rearrange the screen to open one window for each loaded buffer

in the buffer list. When a count is given, this is the

maximum number of windows to open.

:[N]ba[ll] [N] :ba :ball :sba :sballLINK

:[N]sba[ll] [N] Rearrange the screen to open one window for each buffer in

the buffer list. When a count is given, this is the maximum

number of windows to open. 'winheight' also limits the number

of windows opened ('winwidth' if :vertical was prepended).

Buf/Win Enter/Leave autocommands are not executed for the new

windows here, that's only done when they are really entered.

When the :tab modifier is used new windows are opened in a

new tab, up to 'tabpagemax'.

Note: All the commands above that start editing another buffer, keep the

'readonly' flag as it was. This differs from the ":edit" command, which sets

the 'readonly' flag each time the file is read.

==============================================================================

12. Special kinds of buffers special-buffersLINK

Instead of containing the text of a file, buffers can also be used for other

purposes. A few options can be set to change the behavior of a buffer:

'bufhidden' what happens when the buffer is no longer displayed

in a window.

'buftype' what kind of a buffer this is

'swapfile' whether the buffer will have a swap file

'buflisted' buffer shows up in the buffer list

A few useful kinds of a buffer:

quickfix Used to contain the error list or the location list. See

:cwindow and :lwindow. This command sets the 'buftype'

option to "quickfix". You are not supposed to change this!

'swapfile' is off.

help Contains a help file. Will only be created with the :help

command. The flag that indicates a help buffer is internal

and can't be changed. The 'buflisted' option will be reset

for a help buffer.

directory Displays directory contents. Can be used by a file explorer

plugin. The buffer is created with these settings:

:setlocal buftype=nowrite

:setlocal bufhidden=delete

:setlocal noswapfile

The buffer name is the name of the directory and is adjusted

when using the :cd command.

scratch Contains text that can be discarded at any time. It is kept

when closing the window, it must be deleted explicitly.

Settings:

:setlocal buftype=nofile

:setlocal bufhidden=hide

:setlocal noswapfile

The buffer name can be used to identify the buffer, if you

give it a meaningful name.

unlisted-bufferLINK

unlisted The buffer is not in the buffer list. It is not used for

normal editing, but to show a help file, remember a file name

or marks. The ":bdelete" command will also set this option,

thus it doesn't completely delete the buffer. Settings:

:setlocal nobuflisted

vim:tw=78:ts=8:ft=help:norl:
