24==============================================================================
251. Command-line editing					*cmdline-editing*
26
27Normally characters are inserted in front of the cursor position.  You can
28move around in the command-line with the left and right cursor keys.  With the
29<Insert> key, you can toggle between inserting and overstriking characters.
30{Vi: can only alter the last character in the line}
31
32Note that if your keyboard does not have working cursor keys or any of the
33other special keys, you can use ":cnoremap" to define another key for them.
34For example, to define tcsh style editing keys:		*tcsh-style*  >
35	:cnoremap <C-A> <Home>
36	:cnoremap <C-F> <Right>
37	:cnoremap <C-B> <Left>
38	:cnoremap <Esc>b <S-Left>
39	:cnoremap <Esc>f <S-Right>
40(<> notation |<>|; type all this literally)
41
42							*cmdline-too-long*
43When the command line is getting longer than what fits on the screen, only the
44part that fits will be shown.  The cursor can only move in this visible part,
45thus you cannot edit beyond that.
46
47						*cmdline-history* *history*
48The command-lines that you enter are remembered in a history table.  You can
49recall them with the up and down cursor keys.  There are actually five
50history tables:
51- one for ':' commands
52- one for search strings
53- one for expressions
54- one for input lines, typed for the |input()| function.
55- one for debug mode commands
56These are completely separate.  Each history can only be accessed when
57entering the same type of line.
58Use the 'history' option to set the number of lines that are remembered
59(default: 50).
60Notes:
61- When you enter a command-line that is exactly the same as an older one, the
62  old one is removed (to avoid repeated commands moving older commands out of
63  the history).
64- Only commands that are typed are remembered.  Ones that completely come from
65  mappings are not put in the history.
66- All searches are put in the search history, including the ones that come
67  from commands like "*" and "#".  But for a mapping, only the last search is
68  remembered (to avoid that long mappings trash the history).
69{Vi: no history}
70{not available when compiled without the |+cmdline_hist| feature}
71
72There is an automatic completion of names on the command-line; see
73|cmdline-completion|.
74
75							*c_CTRL-V*
76CTRL-V		Insert next non-digit literally.  Up to three digits form the
77		decimal value of a single byte.  The non-digit and the three
78		digits are not considered for mapping.  This works the same
79		way as in Insert mode (see above, |i_CTRL-V|).
80		Note: Under Windows CTRL-V is often mapped to paste text.
81		Use CTRL-Q instead then.
82							*c_CTRL-Q*
83CTRL-Q		Same as CTRL-V.  But with some terminals it is used for
84		control flow, it doesn't work then.
85
86							*c_<Left>* *c_Left*
87<Left>		cursor left
88							*c_<Right>* *c_Right*
89<Right>		cursor right
90							*c_<S-Left>*
91<S-Left> or <C-Left>					*c_<C-Left>*
92		cursor one WORD left
93							*c_<S-Right>*
94<S-Right> or <C-Right>					*c_<C-Right>*
95		cursor one WORD right
96CTRL-B or <Home>				*c_CTRL-B* *c_<Home>* *c_Home*
97		cursor to beginning of command-line
98CTRL-E or <End>					*c_CTRL-E* *c_<End>* *c_End*
99		cursor to end of command-line
100
101							*c_<LeftMouse>*
102<LeftMouse>	Move the cursor to the position of the mouse click.
103
104							*c_<MiddleMouse>*
105<MiddleMouse>	Paste the contents of the clipboard (for X11 the primary
106		selection).  This is similar to using CTRL-R *, but no CR
107		characters are inserted between lines.
108
109CTRL-H						*c_<BS>* *c_CTRL-H* *c_BS*
110<BS>		Delete the character in front of the cursor (see |:fixdel| if
111		your <BS> key does not do what you want).
112							*c_<Del>* *c_Del*
113<Del>		Delete the character under the cursor (at end of line:
114		character before the cursor) (see |:fixdel| if your <Del>
115		key does not do what you want).
116							*c_CTRL-W*
117CTRL-W		Delete the |word| before the cursor.  This depends on the
118		'iskeyword' option.
119							*c_CTRL-U*
120CTRL-U		Remove all characters between the cursor position and
121		the beginning of the line.  Previous versions of vim
122		deleted all characters on the line.  If that is the
123		preferred behavior, add the following to your .vimrc: >
124			:cnoremap <C-U> <C-E><C-U>
125<
126						*c_<Insert>* *c_Insert*
127<Insert>	Toggle between insert and overstrike.  {not in Vi}
128
129{char1} <BS> {char2}	or				*c_digraph*
130CTRL-K {char1} {char2}					*c_CTRL-K*
131		enter digraph (see |digraphs|).  When {char1} is a special
132		key, the code for that key is inserted in <> form.  {not in Vi}
133
134CTRL-R {0-9a-z"%#:-=.}					*c_CTRL-R* *c_<C-R>*
135		Insert the contents of a numbered or named register.  Between
136		typing CTRL-R and the second character '"' will be displayed
137		to indicate that you are expected to enter the name of a
138		register.
139		The text is inserted as if you typed it, but mappings and
140		abbreviations are not used.  Command-line completion through
141		'wildchar' is not triggered though.  And characters that end
142		the command line are inserted literally (<Esc>, <CR>, <NL>,
143		<C-C>).  A <BS> or CTRL-W could still end the command line
144		though, and remaining characters will then be interpreted in
145		another mode, which might not be what you intended.
146		Special registers:
147			'"'	the unnamed register, containing the text of
148				the last delete or yank
149			'%'	the current file name
150			'#'	the alternate file name
151			'*'	the clipboard contents (X11: primary selection)
152			'+'	the clipboard contents
153			'/'	the last search pattern
154			':'	the last command-line
155			'-'	the last small (less than a line) delete
156			'.'	the last inserted text
157							*c_CTRL-R_=*
158			'='	the expression register: you are prompted to
159				enter an expression (see |expression|)
160				(doesn't work at the expression prompt; some
161				things such as changing the buffer or current
162				window are not allowed to avoid side effects)
163				When the result is a |List| the items are used
164				as lines.  They can have line breaks inside
165				too.
166				When the result is a Float it's automatically
167				converted to a String.
168		See |registers| about registers.  {not in Vi}
169		Implementation detail: When using the |expression| register
170		and invoking setcmdpos(), this sets the position before
171		inserting the resulting string.  Use CTRL-R CTRL-R to set the
172		position afterwards.
173
174CTRL-R CTRL-F				*c_CTRL-R_CTRL-F* *c_<C-R>_<C-F>*
175CTRL-R CTRL-P				*c_CTRL-R_CTRL-P* *c_<C-R>_<C-P>*
176CTRL-R CTRL-W				*c_CTRL-R_CTRL-W* *c_<C-R>_<C-W>*
177CTRL-R CTRL-A				*c_CTRL-R_CTRL-A* *c_<C-R>_<C-A>*
178CTRL-R CTRL-L				*c_CTRL-R_CTRL-L* *c_<C-R>_<C-L>*
179		Insert the object under the cursor:
180			CTRL-F	the Filename under the cursor
181			CTRL-P	the Filename under the cursor, expanded with
182				'path' as in |gf|
183			CTRL-W	the Word under the cursor
184			CTRL-A	the WORD under the cursor; see |WORD|
185			CTRL-L	the line under the cursor
186
187		When 'incsearch' is set the cursor position at the end of the
188		currently displayed match is used.  With CTRL-W the part of
189		the word that was already typed is not inserted again.
190
191		{not in Vi}
192		CTRL-F and CTRL-P: {only when |+file_in_path| feature is
193		included}
194
195					*c_CTRL-R_CTRL-R* *c_<C-R>_<C-R>*
196					*c_CTRL-R_CTRL-O* *c_<C-R>_<C-O>*
197CTRL-R CTRL-R {0-9a-z"%#:-=. CTRL-F CTRL-P CTRL-W CTRL-A CTRL-L}
198CTRL-R CTRL-O {0-9a-z"%#:-=. CTRL-F CTRL-P CTRL-W CTRL-A CTRL-L}
199		Insert register or object under the cursor.  Works like
200		|c_CTRL-R| but inserts the text literally.  For example, if
201		register a contains "xy^Hz" (where ^H is a backspace),
202		"CTRL-R a" will insert "xz" while "CTRL-R CTRL-R a" will
203		insert "xy^Hz".
204
205CTRL-\ e {expr}						*c_CTRL-\_e*
206		Evaluate {expr} and replace the whole command line with the
207		result.  You will be prompted for the expression, type <Enter>
208		to finish it.  It's most useful in mappings though.  See
209		|expression|.
210		See |c_CTRL-R_=| for inserting the result of an expression.
211		Useful functions are |getcmdtype()|, |getcmdline()| and
212		|getcmdpos()|.
213		The cursor position is unchanged, except when the cursor was
214		at the end of the line, then it stays at the end.
215		|setcmdpos()| can be used to set the cursor position.
216		The |sandbox| is used for evaluating the expression to avoid
217		nasty side effects.
218		Example: >
219			:cmap <F7> <C-\>eAppendSome()<CR>
220			:func AppendSome()
221			   :let cmd = getcmdline() . " Some()"
222			   :" place the cursor on the )
223			   :call setcmdpos(strlen(cmd))
224			   :return cmd
225			:endfunc
226<		This doesn't work recursively, thus not when already editing
227		an expression.  But it is possible to use in a mapping.
228
229							*c_CTRL-Y*
230CTRL-Y		When there is a modeless selection, copy the selection into
231		the clipboard. |modeless-selection|
232		If there is no selection CTRL-Y is inserted as a character.
233
234CTRL-M or CTRL-J		*c_CTRL-M* *c_CTRL-J* *c_<NL>* *c_<CR>* *c_CR*
235<CR> or <NL>	start entered command
236
237CTRL-[						*c_CTRL-[* *c_<Esc>* *c_Esc*
238<Esc>		When typed and 'x' not present in 'cpoptions', quit
239		Command-line mode without executing.  In macros or when 'x'
240		present in 'cpoptions', start entered command.
241		Note: If your <Esc> key is hard to hit on your keyboard, train
242		yourself to use CTRL-[.
243							*c_CTRL-C*
244CTRL-C		quit command-line without executing
245
246							*c_<Up>* *c_Up*
247<Up>		recall older command-line from history, whose beginning
248		matches the current command-line (see below).
249		{not available when compiled without the |+cmdline_hist|
250		feature}
251							*c_<Down>* *c_Down*
252<Down>		recall more recent command-line from history, whose beginning
253		matches the current command-line (see below).
254		{not available when compiled without the |+cmdline_hist|
255		feature}
256
257							*c_<S-Up>* *c_<PageUp>*
258<S-Up> or <PageUp>
259		recall older command-line from history
260		{not available when compiled without the |+cmdline_hist|
261		feature}
262						*c_<S-Down>* *c_<PageDown>*
263<S-Down> or <PageDown>
264		recall more recent command-line from history
265		{not available when compiled without the |+cmdline_hist|
266		feature}
267
268CTRL-D		command-line completion (see |cmdline-completion|)
269'wildchar' option
270		command-line completion (see |cmdline-completion|)
271CTRL-N		command-line completion (see |cmdline-completion|)
272CTRL-P		command-line completion (see |cmdline-completion|)
273CTRL-A		command-line completion (see |cmdline-completion|)
274CTRL-L		command-line completion (see |cmdline-completion|)
275
276							*c_CTRL-_*
277CTRL-_		a - switch between Hebrew and English keyboard mode, which is
278		private to the command-line and not related to hkmap.
279		This is useful when Hebrew text entry is required in the
280		command-line, searches, abbreviations, etc.  Applies only if
281		Vim is compiled with the |+rightleft| feature and the
282		'allowrevins' option is set.
283		See |rileft.txt|.
284
285		b - switch between Farsi and English keyboard mode, which is
286		private to the command-line and not related to fkmap.  In
287		Farsi keyboard mode the characters are inserted in reverse
288		insert manner.  This is useful when Farsi text entry is
289		required in the command-line, searches, abbreviations, etc.
290		Applies only if Vim is compiled with the |+farsi| feature.
291		See |farsi.txt|.
292
293							*c_CTRL-^*
294CTRL-^		Toggle the use of language |:lmap| mappings and/or Input
295		Method.
296		When typing a pattern for a search command and 'imsearch' is
297		not -1, VAL is the value of 'imsearch', otherwise VAL is the
298		value of 'iminsert'.
299		When language mappings are defined:
300		- If VAL is 1 (langmap mappings used) it becomes 0 (no langmap
301		  mappings used).
302		- If VAL was not 1 it becomes 1, thus langmap mappings are
303		  enabled.
304		When no language mappings are defined:
305		- If VAL is 2 (Input Method is used) it becomes 0 (no input
306		  method used)
307		- If VAL has another value it becomes 2, thus the Input Method
308		  is enabled.
309		These language mappings are normally used to type characters
310		that are different from what the keyboard produces.  The
311		'keymap' option can be used to install a whole number of them.
312		When entering a command line, langmap mappings are switched
313		off, since you are expected to type a command.  After
314		switching it on with CTRL-^, the new state is not used again
315		for the next command or Search pattern.
316		{not in Vi}
317
318						*c_CTRL-]*
319CTRL-]		Trigger abbreviation, without inserting a character.  {not in
320		Vi}
321
322For Emacs-style editing on the command-line see |emacs-keys|.
323
324The <Up> and <Down> keys take the current command-line as a search string.
325The beginning of the next/previous command-lines are compared with this
326string.  The first line that matches is the new command-line.  When typing
327these two keys repeatedly, the same string is used again.  For example, this
328can be used to find the previous substitute command: Type ":s" and then <Up>.
329The same could be done by typing <S-Up> a number of times until the desired
330command-line is shown.  (Note: the shifted arrow keys do not work on all
331terminals)
332
333							*:his* *:history*
334:his[tory]	Print the history of last entered commands.
335		{not in Vi}
336		{not available when compiled without the |+cmdline_hist|
337		feature}
338
339:his[tory] [{name}] [{first}][, [{last}]]
340		List the contents of history {name} which can be:
341		c[md]	 or :		command-line history
342		s[earch] or / or ?	search string history
343		e[xpr]	 or =		expression register history
344		i[nput]	 or @		input line history
345		d[ebug]	 or >		debug command history
346		a[ll]			all of the above
347		{not in Vi}
348
349		If the numbers {first} and/or {last} are given, the respective
350		range of entries from a history is listed.  These numbers can
351		be specified in the following form:
352							*:history-indexing*
353		A positive number represents the absolute index of an entry
354		as it is given in the first column of a :history listing.
355		This number remains fixed even if other entries are deleted.
356
357		A negative number means the relative position of an entry,
358		counted from the newest entry (which has index -1) backwards.
359
360		Examples:
361		List entries 6 to 12 from the search history: >
362			:history / 6,12
363<
364		List the penultimate entry from all histories: >
365			:history all -2
366<
367		List the most recent two entries from all histories: >
368			:history all -2,
369
370:keepp[atterns] {command}			*:keepp* *:keeppatterns*
371		Execute {command}, without adding anything to the search
372		history
373
374==============================================================================
3752. Command-line completion				*cmdline-completion*
376
377When editing the command-line, a few commands can be used to complete the
378word before the cursor.  This is available for:
379
380- Command names: At the start of the command-line.
381- Tags: Only after the ":tag" command.
382- File names: Only after a command that accepts a file name or a setting for
383  an option that can be set to a file name.  This is called file name
384  completion.
385- Shell command names: After ":!cmd", ":r !cmd" and ":w !cmd".  $PATH is used.
386- Options: Only after the ":set" command.
387- Mappings: Only after a ":map" or similar command.
388- Variable and function names: Only after a ":if", ":call" or similar command.
389
390When Vim was compiled without the |+cmdline_compl| feature only file names,
391directories and help items can be completed.  The number of help item matches
392is limited (currently to 300) to avoid a long delay when there are very many
393matches.
394
395These are the commands that can be used:
396
397							*c_CTRL-D*
398CTRL-D		List names that match the pattern in front of the cursor.
399		When showing file names, directories are highlighted (see
400		'highlight' option).  Names where 'suffixes' matches are moved
401		to the end.
402		The 'wildoptions' option can be set to "tagfile" to list the
403		file of matching tags.
404					*c_CTRL-I* *c_wildchar* *c_<Tab>*
405'wildchar' option
406		A match is done on the pattern in front of the cursor.  The
407		match (if there are several, the first match) is inserted
408		in place of the pattern.  (Note: does not work inside a
409		macro, because <Tab> or <Esc> are mostly used as 'wildchar',
410		and these have a special meaning in some macros.) When typed
411		again and there were multiple matches, the next
412		match is inserted.  After the last match, the first is used
413		again (wrap around).
414		The behavior can be changed with the 'wildmode' option.
415							*c_<S-Tab>*
416<S-Tab>		Like 'wildchar' or <Tab>, but begin with the last match and
417		then go to the previous match.
418		<S-Tab> does not work everywhere.
419							*c_CTRL-N*
420CTRL-N		After using 'wildchar' which got multiple matches, go to next
421		match.  Otherwise recall more recent command-line from history.
422							*c_CTRL-P*
423CTRL-P		After using 'wildchar' which got multiple matches, go to
424		previous match.  Otherwise recall older command-line from
425		history.
426							*c_CTRL-A*
427CTRL-A		All names that match the pattern in front of the cursor are
428		inserted.
429							*c_CTRL-L*
430CTRL-L		A match is done on the pattern in front of the cursor.  If
431		there is one match, it is inserted in place of the pattern.
432		If there are multiple matches the longest common part is
433		inserted in place of the pattern.  If the result is shorter
434		than the pattern, no completion is done.
435							*/_CTRL-L*
436		When 'incsearch' is set, entering a search pattern for "/" or
437		"?" and the current match is displayed then CTRL-L will add
438		one character from the end of the current match.  If
439		'ignorecase' and 'smartcase' are set and the command line has
440		no uppercase characters, the added character is converted to
441		lowercase.
442	                                            *c_CTRL-G* */_CTRL-G*
443CTRL-G		When 'incsearch' is set, entering a search pattern for "/" or
444		"?" and the current match is displayed then CTRL-G will move
445		to the next match (does not take |search-offset| into account)
446		Use CTRL-T to move to the previous match.  Hint: on a regular
447		keyboard T is above G.
448	                                            *c_CTRL-T* */_CTRL-T*
449CTRL-T		When 'incsearch' is set, entering a search pattern for "/" or
450		"?" and the current match is displayed then CTRL-T will move
451		to the previous match (does not take |search-offset| into
452		account).
453		Use CTRL-G to move to the next match.  Hint: on a regular
454		keyboard T is above G.
455
456The 'wildchar' option defaults to <Tab> (CTRL-E when in Vi compatible mode; in
457a previous version <Esc> was used).  In the pattern standard wildcards '*' and
458'?' are accepted when matching file names.  '*' matches any string, '?'
459matches exactly one character.
460
461When repeating 'wildchar' or CTRL-N you cycle through the matches, eventually
462ending up back to what was typed.  If the first match is not what you wanted,
463you can use <S-Tab> or CTRL-P to go straight back to what you typed.
464
465The 'wildignorecase' option can be set to ignore case in filenames.
466
467The 'wildmenu' option can be set to show the matches just above the command
468line.
469
470If you like tcsh's autolist completion, you can use this mapping:
471	:cnoremap X <C-L><C-D>
472(Where X is the command key to use, <C-L> is CTRL-L and <C-D> is CTRL-D)
473This will find the longest match and then list all matching files.
474
475If you like tcsh's autolist completion, you can use the 'wildmode' option to
476emulate it.  For example, this mimics autolist=ambiguous:
477	:set wildmode=longest,list
478This will find the longest match with the first 'wildchar', then list all
479matching files with the next.
480
481							*suffixes*
482For file name completion you can use the 'suffixes' option to set a priority
483between files with almost the same name.  If there are multiple matches,
484those files with an extension that is in the 'suffixes' option are ignored.
485The default is ".bak,~,.o,.h,.info,.swp,.obj", which means that files ending
486in ".bak", "~", ".o", ".h", ".info", ".swp" and ".obj" are sometimes ignored.
487
488An empty entry, two consecutive commas, match a file name that does not
489contain a ".", thus has no suffix.  This is useful to ignore "prog" and prefer
490"prog.c".
491
492Examples:
493
494  pattern:	files:				match:	~
495   test*	test.c test.h test.o		test.c
496   test*	test.h test.o			test.h and test.o
497   test*	test.i test.h test.c		test.i and test.c
498
499It is impossible to ignore suffixes with two dots.
500
501If there is more than one matching file (after ignoring the ones matching
502the 'suffixes' option) the first file name is inserted.  You can see that
503there is only one match when you type 'wildchar' twice and the completed
504match stays the same.  You can get to the other matches by entering
505'wildchar', CTRL-N or CTRL-P.  All files are included, also the ones with
506extensions matching the 'suffixes' option.
507
508To completely ignore files with some extension use 'wildignore'.
509
510To match only files that end at the end of the typed text append a "$".  For
511example, to match only files that end in ".c": >
512	:e *.c$
513This will not match a file ending in ".cpp".  Without the "$" it does match.
514
515The old value of an option can be obtained by hitting 'wildchar' just after
516the '='.  For example, typing 'wildchar' after ":set dir=" will insert the
517current value of 'dir'.  This overrules file name completion for the options
518that take a file name.
519
520If you would like using <S-Tab> for CTRL-P in an xterm, put this command in
521your .cshrc: >
522	xmodmap -e "keysym Tab = Tab Find"
523And this in your .vimrc: >
524	:cmap <Esc>[1~ <C-P>
525
526==============================================================================
5273. Ex command-lines					*cmdline-lines*
528
529The Ex commands have a few specialties:
530
531							*:quote* *:comment*
532'"' at the start of a line causes the whole line to be ignored.  '"'
533after a command causes the rest of the line to be ignored.  This can be used
534to add comments.  Example: >
535	:set ai		"set 'autoindent' option
536It is not possible to add a comment to a shell command ":!cmd" or to the
537":map" command and a few others (mainly commands that expect expressions)
538that see the '"' as part of their argument:
539
540    :argdo
541    :autocmd
542    :bufdo
543    :cexpr (and the like)
544    :cdo (and the like)
545    :command
546    :cscope (and the like)
547    :debug
548    :display
549    :echo (and the like)
550    :elseif
551    :execute
552    :folddoopen
553    :folddoclosed
554    :for
555    :grep (and the like)
556    :help (and the like)
557    :if
558    :let
559    :make
560    :map (and the like including :abbrev commands)
561    :menu (and the like)
562    :mkspell
563    :normal
564    :ownsyntax
565    :popup
566    :promptfind (and the like)
567    :registers
568    :return
569    :sort
570    :syntax
571    :tabdo
572    :tearoff
573    :vimgrep (and the like)
574    :while
575    :windo
576
577							*:bar* *:\bar*
578'|' can be used to separate commands, so you can give multiple commands in one
579line.  If you want to use '|' in an argument, precede it with '\'.
580
581These commands see the '|' as their argument, and can therefore not be
582followed by another Vim command:
583    :argdo
584    :autocmd
585    :bufdo
586    :cdo
587    :cfdo
588    :command
589    :cscope
590    :debug
591    :folddoopen
592    :folddoclosed
593    :function
594    :global
595    :help
596    :helpfind
597    :lcscope
598    :ldo
599    :lfdo
600    :make
601    :normal
602    :perl
603    :perldo
604    :promptfind
605    :promptrepl
606    :pyfile
607    :python
608    :registers
609    :read !
610    :scscope
611    :sign
612    :tcl
613    :tcldo
614    :tclfile
615    :vglobal
616    :windo
617    :write !
618    :[range]!
619    a user defined command without the "-bar" argument |:command|
620
621Note that this is confusing (inherited from Vi): With ":g" the '|' is included
622in the command, with ":s" it is not.
623
624To be able to use another command anyway, use the ":execute" command.
625Example (append the output of "ls" and jump to the first line): >
626	:execute 'r !ls' | '[
627
628There is one exception: When the 'b' flag is present in 'cpoptions', with the
629":map" and ":abbr" commands and friends CTRL-V needs to be used instead of
630'\'.  You can also use "<Bar>" instead.  See also |map_bar|.
631
632Examples: >
633	:!ls | wc		view the output of two commands
634	:r !ls | wc		insert the same output in the text
635	:%g/foo/p|>		moves all matching lines one shiftwidth
636	:%s/foo/bar/|>		moves one line one shiftwidth
637	:map q 10^V|		map "q" to "10|"
638	:map q 10\| map \ l	map "q" to "10\" and map "\" to "l"
639					(when 'b' is present in 'cpoptions')
640
641You can also use <NL> to separate commands in the same way as with '|'.  To
642insert a <NL> use CTRL-V CTRL-J.  "^@" will be shown.  Using '|' is the
643preferred method.  But for external commands a <NL> must be used, because a
644'|' is included in the external command.  To avoid the special meaning of <NL>
645it must be preceded with a backslash.  Example: >
646	:r !date<NL>-join
647This reads the current date into the file and joins it with the previous line.
648
649Note that when the command before the '|' generates an error, the following
650commands will not be executed.
651
652
653Because of Vi compatibility the following strange commands are supported: >
654	:|			print current line (like ":p")
655	:3|			print line 3 (like ":3p")
656	:3			goto line 3
657
658A colon is allowed between the range and the command name.  It is ignored
659(this is Vi compatible).  For example: >
660	:1,$:s/pat/string
661
662When the character '%' or '#' is used where a file name is expected, they are
663expanded to the current and alternate file name (see the chapter "editing
664files" |:_%| |:_#|).
665
666Embedded spaces in file names are allowed on the Amiga if one file name is
667expected as argument.  Trailing spaces will be ignored, unless escaped with a
668backslash or CTRL-V.  Note that the ":next" command uses spaces to separate
669file names.  Escape the spaces to include them in a file name.  Example: >
670	:next foo\ bar goes\ to school\
671starts editing the three files "foo bar", "goes to" and "school ".
672
673When you want to use the special characters '"' or '|' in a command, or want
674to use '%' or '#' in a file name, precede them with a backslash.  The
675backslash is not required in a range and in the ":substitute" command.
676See also |`=|.
677
678							*:_!*
679The '!' (bang) character after an Ex command makes the command behave in a
680different way.  The '!' should be placed immediately after the command, without
681any blanks in between.  If you insert blanks the '!' will be seen as an
682argument for the command, which has a different meaning.  For example:
683	:w! name	write the current buffer to file "name", overwriting
684			any existing file
685	:w !name	send the current buffer as standard input to command
686			"name"
687
688==============================================================================
6894. Ex command-line ranges	*cmdline-ranges* *[range]* *E16*
690
691Some Ex commands accept a line range in front of them.  This is noted as
692[range].  It consists of one or more line specifiers, separated with ',' or
693';'.
694
695The basics are explained in section |10.3| of the user manual.
696
697						*:,* *:;*
698When separated with ';' the cursor position will be set to that line
699before interpreting the next line specifier.  This doesn't happen for ','.
700Examples: >
701   4,/this line/
702<	from line 4 till match with "this line" after the cursor line. >
703   5;/that line/
704<	from line 5 till match with "that line" after line 5.
705
706The default line specifier for most commands is the cursor position, but the
707commands ":write" and ":global" have the whole file (1,$) as default.
708
709If more line specifiers are given than required for the command, the first
710one(s) will be ignored.
711
712Line numbers may be specified with:		*:range* *E14* *{address}*
713	{number}	an absolute line number
714	.		the current line			  *:.*
715	$		the last line in the file		  *:$*
716	%		equal to 1,$ (the entire file)		  *:%*
717	't		position of mark t (lowercase)		  *:'*
718	'T		position of mark T (uppercase); when the mark is in
719			another file it cannot be used in a range
720	/{pattern}[/]	the next line where {pattern} matches	  *:/*
721	?{pattern}[?]	the previous line where {pattern} matches *:?*
722	\/		the next line where the previously used search
723			pattern matches
724	\?		the previous line where the previously used search
725			pattern matches
726	\&		the next line where the previously used substitute
727			pattern matches
728
729Each may be followed (several times) by '+' or '-' and an optional number.
730This number is added or subtracted from the preceding line number.  If the
731number is omitted, 1 is used.
732
733The "/" and "?" after {pattern} are required to separate the pattern from
734anything that follows.
735
736The "/" and "?" may be preceded with another address.  The search starts from
737there.  The difference from using ';' is that the cursor isn't moved.
738Examples: >
739	/pat1//pat2/	Find line containing "pat2" after line containing
740			"pat1", without moving the cursor.
741	7;/pat2/	Find line containing "pat2", after line 7, leaving
742			the cursor in line 7.
743
744The {number} must be between 0 and the number of lines in the file.  When
745using a 0 (zero) this is interpreted as a 1 by most commands.  Commands that
746use it as a count do use it as a zero (|:tag|, |:pop|, etc).  Some commands
747interpret the zero as "before the first line" (|:read|, search pattern, etc).
748
749Examples: >
750	.+3		three lines below the cursor
751	/that/+1	the line below the next line containing "that"
752	.,$		from current line until end of file
753	0;/that		the first line containing "that", also matches in the
754			first line.
755	1;/that		the first line after line 1 containing "that"
756
757Some commands allow for a count after the command.  This count is used as the
758number of lines to be used, starting with the line given in the last line
759specifier (the default is the cursor line).  The commands that accept a count
760are the ones that use a range but do not have a file name argument (because
761a file name can also be a number).
762
763Examples: >
764	:s/x/X/g 5	substitute 'x' by 'X' in the current line and four
765			following lines
766	:23d 4		delete lines 23, 24, 25 and 26
767
768
769Folds and Range
770
771When folds are active the line numbers are rounded off to include the whole
772closed fold.  See |fold-behavior|.
773
774
775Reverse Range						*E493*
776
777A range should have the lower line number first.  If this is not the case, Vim
778will ask you if it should swap the line numbers.
779	Backwards range given, OK to swap ~
780This is not done within the global command ":g".
781
782You can use ":silent" before a command to avoid the question, the range will
783always be swapped then.
784
785
786Count and Range						*N:*
787
788When giving a count before entering ":", this is translated into:
789		:.,.+(count - 1)
790In words: The 'count' lines at and after the cursor.  Example: To delete
791three lines: >
792		3:d<CR>		is translated into: .,.+2d<CR>
793<
794
795Visual Mode and Range					*v_:*
796
797{Visual}:	Starts a command-line with the Visual selected lines as a
798		range.  The code `:'<,'>` is used for this range, which makes
799		it possible to select a similar line from the command-line
800		history for repeating a command on different Visually selected
801		lines.
802		When Visual mode was already ended, a short way to use the
803		Visual area for a range is `:*`.  This requires that "*" does
804		not appear in 'cpo', see |cpo-star|.  Otherwise you will have
805		to type `:'<,'>`
806
807
808==============================================================================
8095. Ex command-line flags				*ex-flags*
810
811These flags are supported by a selection of Ex commands.  They print the line
812that the cursor ends up after executing the command:
813
814	l	output like for |:list|
815	#	add line number
816	p	output like for |:print|
817
818The flags can be combined, thus "l#" uses both a line number and |:list| style
819output.
820
821==============================================================================
8226. Ex special characters				*cmdline-special*
823
824Note: These are special characters in the executed command line.  If you want
825to insert special things while typing you can use the CTRL-R command.  For
826example, "%" stands for the current file name, while CTRL-R % inserts the
827current file name right away.  See |c_CTRL-R|.
828
829Note:  If you want to avoid the effects of special characters in a Vim script
830you may want to use |fnameescape()|.  Also see |`=|.
831
832
833In Ex commands, at places where a file name can be used, the following
834characters have a special meaning.  These can also be used in the expression
835function |expand()|.
836	%	Is replaced with the current file name.		  *:_%* *c_%*
837	#	Is replaced with the alternate file name.	  *:_#* *c_#*
838		This is remembered for every window.
839	#n	(where n is a number) is replaced with		  *:_#0* *:_#n*
840		the file name of buffer n.  "#0" is the same as "#".     *c_#n*
841	##	Is replaced with all names in the argument list	  *:_##* *c_##*
842		concatenated, separated by spaces.  Each space in a name
843		is preceded with a backslash.
844	#<n	(where n is a number > 0) is replaced with old	  *:_#<* *c_#<*
845		file name n.  See |:oldfiles| or |v:oldfiles| to get the
846		number.							*E809*
847		{only when compiled with the |+eval| and |+viminfo| features}
848
849Note that these, except "#<n", give the file name as it was typed.  If an
850absolute path is needed (when using the file name from a different directory),
851you need to add ":p".  See |filename-modifiers|.
852
853The "#<n" item returns an absolute path, but it will start with "~/" for files
854below your home directory.
855
856Note that backslashes are inserted before spaces, so that the command will
857correctly interpret the file name.  But this doesn't happen for shell
858commands.  For those you probably have to use quotes (this fails for files
859that contain a quote and wildcards): >
860	:!ls "%"
861	:r !spell "%"
862
863To avoid the special meaning of '%' and '#' insert a backslash before it.
864Detail: The special meaning is always escaped when there is a backslash before
865it, no matter how many backslashes.
866	you type:		result	~
867	   #			alternate.file
868	   \#			#
869	   \\#			\#
870Also see |`=|.
871
872			       *:<cword>* *<cword>* *:<cWORD>* *<cWORD>*
873			       *:<cexpr>* *<cexpr>* *:<cfile>* *<cfile>*
874			       *:<afile>* *<afile>* *:<abuf>* *<abuf>*
875			       *:<amatch>* *<amatch>*
876			       *:<sfile>* *<sfile>* *:<slnum>* *<slnum>*
877			       *:<sflnum>* *<sflnum>* *E499* *E500*
878Note: these are typed literally, they are not special keys!
879	<cword>    is replaced with the word under the cursor (like |star|)
880	<cWORD>    is replaced with the WORD under the cursor (see |WORD|)
881	<cexpr>    is replaced with the word under the cursor, including more
882		   to form a C expression.  E.g., when the cursor is on "arg"
883		   of "ptr->arg" then the result is "ptr->arg"; when the
884		   cursor is on "]" of "list[idx]" then the result is
885		   "list[idx]".  This is used for |v:beval_text|.
886	<cfile>    is replaced with the path name under the cursor (like what
887		   |gf| uses)
888	<afile>    When executing autocommands, is replaced with the file name
889		   of the buffer being manipulated, or the file for a read or
890		   write.  *E495*
891	<abuf>     When executing autocommands, is replaced with the currently
892		   effective buffer number (for ":r file" and ":so file" it is
893		   the current buffer, the file being read/sourced is not in a
894		   buffer).  *E496*
895	<amatch>   When executing autocommands, is replaced with the match for
896		   which this autocommand was executed.  *E497*
897		   It differs from <afile> only when the file name isn't used
898		   to match with (for FileType, Syntax and SpellFileMissing
899		   events).
900	<sfile>    When executing a ":source" command, is replaced with the
901		   file name of the sourced file.  *E498*
902		   When executing a function, is replaced with:
903		   "function {function-name}[{lnum}]"
904		   function call nesting is indicated like this:
905		   "function {function-name1}[{lnum}]..{function-name2}[{lnum}]"
906		   Note that filename-modifiers are useless when <sfile> is
907		   used inside a function.
908	<slnum>	   When executing a ":source" command, is replaced with the
909		   line number.  *E842*
910		   When executing a function it's the line number relative to
911		   the start of the function.
912	<sflnum>   When executing a script, is replaced with the line number.
913		   It differs from <slnum> in that <sflnum> is replaced with
914		   the script line number in any situation.  *E961*
915
916							 *filename-modifiers*
917*:_%:* *::8* *::p* *::.* *::~* *::h* *::t* *::r* *::e* *::s* *::gs* *::S*
918     *%:8* *%:p* *%:.* *%:~* *%:h* *%:t* *%:r* *%:e* *%:s* *%:gs* *%:S*
919The file name modifiers can be used after "%", "#", "#n", "<cfile>", "<sfile>",
920"<afile>" or "<abuf>".  They are also used with the |fnamemodify()| function.
921These are not available when Vim has been compiled without the |+modify_fname|
922feature.
923These modifiers can be given, in this order:
924	:p	Make file name a full path.  Must be the first modifier.  Also
925		changes "~/" (and "~user/" for Unix and VMS) to the path for
926		the home directory.  If the name is a directory a path
927		separator is added at the end.  For a file name that does not
928		exist and does not have an absolute path the result is
929		unpredictable.  On MS-Windows an 8.3 filename is expanded to
930		the long name.
931	:8	Converts the path to 8.3 short format (currently only on
932		MS-Windows).  Will act on as much of a path that is an
933		existing path.
934	:~	Reduce file name to be relative to the home directory, if
935		possible.  File name is unmodified if it is not below the home
936		directory.
937	:.	Reduce file name to be relative to current directory, if
938		possible.  File name is unmodified if it is not below the
939		current directory, but on MS-Windows the drive is removed if
940		it is the current drive.
941		For maximum shortness, use ":~:.".
942	:h	Head of the file name (the last component and any separators
943		removed).  Cannot be used with :e, :r or :t.
944		Can be repeated to remove several components at the end.
945		When the file name ends in a path separator, only the path
946		separator is removed.  Thus ":p:h" on a directory name results
947		on the directory name itself (without trailing slash).
948		When the file name is an absolute path (starts with "/" for
949		Unix; "x:\" for MS-DOS, WIN32, OS/2; "drive:" for Amiga), that
950		part is not removed.  When there is no head (path is relative
951		to current directory) the result is empty.
952	:t	Tail of the file name (last component of the name).  Must
953		precede any :r or :e.
954	:r	Root of the file name (the last extension removed).  When
955		there is only an extension (file name that starts with '.',
956		e.g., ".vimrc"), it is not removed.  Can be repeated to remove
957		several extensions (last one first).
958	:e	Extension of the file name.  Only makes sense when used alone.
959		When there is no extension the result is empty.
960		When there is only an extension (file name that starts with
961		'.'), the result is empty.  Can be repeated to include more
962		extensions.  If there are not enough extensions (but at least
963		one) as much as possible are included.
964	:s?pat?sub?
965		Substitute the first occurrence of "pat" with "sub".  This
966		works like the |:s| command.  "pat" is a regular expression.
967		Any character can be used for '?', but it must not occur in
968		"pat" or "sub".
969		After this, the previous modifiers can be used again.  For
970		example ":p", to make a full path after the substitution.
971	:gs?pat?sub?
972		Substitute all occurrences of "pat" with "sub".  Otherwise
973		this works like ":s".
974	:S	Escape special characters for use with a shell command (see
975		|shellescape()|). Must be the last one. Examples: >
976		    :!dir <cfile>:S
977		    :call system('chmod +w -- ' . expand('%:S'))
978
979Examples, when the file name is "src/version.c", current dir
980"/home/mool/vim": >
981  :p			/home/mool/vim/src/version.c
982  :p:.				       src/version.c
983  :p:~				 ~/vim/src/version.c
984  :h				       src
985  :p:h			/home/mool/vim/src
986  :p:h:h		/home/mool/vim
987  :t					   version.c
988  :p:t					   version.c
989  :r				       src/version
990  :p:r			/home/mool/vim/src/version
991  :t:r					   version
992  :e						   c
993  :s?version?main?		       src/main.c
994  :s?version?main?:p	/home/mool/vim/src/main.c
995  :p:gs?/?\\?		\home\mool\vim\src\version.c
996
997Examples, when the file name is "src/version.c.gz": >
998  :p			/home/mool/vim/src/version.c.gz
999  :e						     gz
1000  :e:e						   c.gz
1001  :e:e:e					   c.gz

1006  :r:r:r			       src/version
1007<
1008					*extension-removal* *:_%<*
1009If a "<" is appended to "%", "#", "#n" or "CTRL-V p" the extension of the file
1010name is removed (everything after and including the last '.' in the file
1011name).  This is included for backwards compatibility with version 3.0, the
1012":r" form is preferred.  Examples: >
1013
1014	%		current file name
1015	%<		current file name without extension
1016	#		alternate file name for current window
1017	#<		idem, without extension
1018	#31		alternate file number 31
1019	#31<		idem, without extension
1020	<cword>		word under the cursor
1021	<cWORD>		WORD under the cursor (see |WORD|)
1022	<cfile>		path name under the cursor
1023	<cfile><	idem, without extension
1024
1025Note: Where a file name is expected wildcards expansion is done.  On Unix the
1026shell is used for this, unless it can be done internally (for speed).
1027Unless in |restricted-mode|, backticks work also, like in >
1028	:n `echo *.c`
1029But expansion is only done if there are any wildcards before expanding the
1030'%', '#', etc..  This avoids expanding wildcards inside a file name.  If you
1031want to expand the result of <cfile>, add a wildcard character to it.
1032Examples: (alternate file name is "?readme?")
1033	command		expands to  ~
1034	:e #		:e ?readme?
1035	:e `ls #`	:e {files matching "?readme?"}
1036	:e #.*		:e {files matching "?readme?.*"}
1037	:cd <cfile>	:cd {file name under cursor}
1038	:cd <cfile>*	:cd {file name under cursor plus "*" and then expanded}
1039Also see |`=|.
1040
1041When the expanded argument contains a "!" and it is used for a shell command
1042(":!cmd", ":r !cmd" or ":w !cmd"), the "!" is escaped with a backslash to
1043avoid it being expanded into a previously used command.  When the 'shell'
1044option contains "sh", this is done twice, to avoid the shell trying to expand
1045the "!".
1046
1047							*filename-backslash*
1048For filesystems that use a backslash as directory separator (MS-DOS, Windows,
1049OS/2), it's a bit difficult to recognize a backslash that is used to escape
1050the special meaning of the next character.  The general rule is: If the
1051backslash is followed by a normal file name character, it does not have a
1052special meaning.  Therefore "\file\foo" is a valid file name, you don't have
1053to type the backslash twice.
1054
1055An exception is the '$' sign.  It is a valid character in a file name.  But
1056to avoid a file name like "$home" to be interpreted as an environment variable,
1057it needs to be preceded by a backslash.  Therefore you need to use "/\$home"
1058for the file "$home" in the root directory.  A few examples:
1059
1060	FILE NAME	INTERPRETED AS	~
1061	$home		expanded to value of environment var $home
1062	\$home		file "$home" in current directory
1063	/\$home		file "$home" in root directory
1064	\\$home		file "\\", followed by expanded $home
1065

10697. Command-line window				*cmdline-window* *cmdwin*
1070							*command-line-window*
1071In the command-line window the command line can be edited just like editing
1072text in any window.  It is a special kind of window, because you cannot leave
1073it in a normal way.
1074{not available when compiled without the |+cmdline_hist| or |+vertsplit|
1075feature}
1076
1077
1078OPEN						*c_CTRL-F* *q:* *q/* *q?*
1079
1080There are two ways to open the command-line window:
10811. From Command-line mode, use the key specified with the 'cedit' option.
1082   The default is CTRL-F when 'compatible' is not set.
10832. From Normal mode, use the "q:", "q/" or "q?" command.
1084   This starts editing an Ex command-line ("q:") or search string ("q/" or
1085   "q?").  Note that this is not possible while recording is in progress (the
1086   "q" stops recording then).
1087
1088When the window opens it is filled with the command-line history.  The last
1089line contains the command as typed so far.  The left column will show a
1090character that indicates the type of command-line being edited, see
1091|cmdwin-char|.
1092
1093Vim will be in Normal mode when the editor is opened, except when 'insertmode'
1094is set.
1095
1096The height of the window is specified with 'cmdwinheight' (or smaller if there
1097is no room).  The window is always full width and is positioned just above the
1098command-line.
1099
1100
1101EDIT
1102
1103You can now use commands to move around and edit the text in the window.  Both
1104in Normal mode and Insert mode.
1105
1106It is possible to use ":", "/" and other commands that use the command-line,
1107but it's not possible to open another command-line window then.  There is no
1108nesting.
1109							*E11*
1110The command-line window is not a normal window.  It is not possible to move to
1111another window or edit another buffer.  All commands that would do this are
1112disabled in the command-line window.  Of course it _is_ possible to execute
1113any command that you entered in the command-line window.  Other text edits are
1114discarded when closing the window.
1115
1116
1117CLOSE							*E199*
1118
1119There are several ways to leave the command-line window:
1120
1121<CR>		Execute the command-line under the cursor.  Works both in
1122		Insert and in Normal mode.
1123CTRL-C		Continue in Command-line mode.  The command-line under the
1124		cursor is used as the command-line.  Works both in Insert and
1125		in Normal mode.  There is no redraw, thus the window will
1126		remain visible.
1127:quit		Discard the command line and go back to Normal mode.
1128		":close", ":exit", ":xit" and CTRL-\ CTRL-N also work.
1129:qall		Quit Vim, unless there are changes in some buffer.
1130:qall!		Quit Vim, discarding changes to any buffer.
1131
1132Once the command-line window is closed the old window sizes are restored.  The
1133executed command applies to the window and buffer where the command-line was
1134started from.  This works as if the command-line window was not there, except
1135that there will be an extra screen redraw.
1136The buffer used for the command-line window is deleted.  Any changes to lines
1137other than the one that is executed with <CR> are lost.
1138
1139If you would like to execute the command under the cursor and then have the
1140command-line window open again, you may find this mapping useful: >
1141
1142	:autocmd CmdwinEnter * map <buffer> <F5> <CR>q:
1143
1144
1145VARIOUS
1146
1147The command-line window cannot be used:
1148- when there already is a command-line window (no nesting)
1149- for entering an encryption key or when using inputsecret()
1150- when Vim was not compiled with the |+vertsplit| feature
1151
1152Some options are set when the command-line window is opened:
1153'filetype'	"vim", when editing an Ex command-line; this starts Vim syntax
1154		highlighting if it was enabled
1155'rightleft'	off
1156'modifiable'	on
1157'buftype'	"nofile"
1158'swapfile'	off
1159
1160It is allowed to write the buffer contents to a file.  This is an easy way to
1161save the command-line history and read it back later.
1162
1163If the 'wildchar' option is set to <Tab>, and the command-line window is used
1164for an Ex command, then two mappings will be added to use <Tab> for completion
1165in the command-line window, like this: >
1166	:imap <buffer> <Tab> <C-X><C-V>
1167	:nmap <buffer> <Tab> a<C-X><C-V>
1168Note that hitting <Tab> in Normal mode will do completion on the next
1169character.  That way it works at the end of the line.
1170If you don't want these mappings, disable them with: >
1171	au CmdwinEnter [:>] iunmap <Tab>
1172	au CmdwinEnter [:>] nunmap <Tab>
1173You could put these lines in your vimrc file.
1174
1175While in the command-line window you cannot use the mouse to put the cursor in
1176another window, or drag statuslines of other windows.  You can drag the
1177statusline of the command-line window itself and the statusline above it.
1178Thus you can resize the command-line window, but not others.
1179
1180The |getcmdwintype()| function returns the type of the command-line being
1181edited as described in |cmdwin-char|.
1182
1183
1184AUTOCOMMANDS
1185
1186Two autocommand events are used: |CmdwinEnter| and |CmdwinLeave|.  Since this
1187window is of a special type, the WinEnter, WinLeave, BufEnter and BufLeave
1188events are not triggered.  You can use the Cmdwin events to do settings
1189specifically for the command-line window.  Be careful not to cause side
1190effects!
1191Example: >
1192	:au CmdwinEnter :  let b:cpt_save = &cpt | set cpt=.
1193	:au CmdwinLeave :  let &cpt = b:cpt_save
1194This sets 'complete' to use completion in the current window for |i_CTRL-N|.
1195Another example: >
1196	:au CmdwinEnter [/?]  startinsert
1197This will make Vim start in Insert mode in the command-line window.
1198
1199						*cmdwin-char*
1200The character used for the pattern indicates the type of command-line:
1201	:	normal Ex command
1202	>	debug mode command |debug-mode|
1203	/	forward search string
1204	?	backward search string
1205	=	expression for "= |expr-register|
1206	@	string for |input()|
1207	-	text for |:insert| or |:append|
