26 ============================================================================== | |
27 1. Introduction *autocmd-intro* | |
28 | |
22 | 29 You can specify commands to be executed automatically when reading or writing |
30 a file, when entering or leaving a buffer or window, and when exiting Vim. | |
31 For example, you can create an autocommand to set the 'cindent' option for | |
32 files matching *.c. You can also use autocommands to implement advanced | |
7 | 33 features, such as editing compressed files (see |gzip-example|). The usual |
34 place to put autocommands is in your .vimrc or .exrc file. | |
35 | |
3371 | 36 *E203* *E204* *E143* *E855* |
7 | 37 WARNING: Using autocommands is very powerful, and may lead to unexpected side |
38 effects. Be careful not to destroy your text. | |
39 - It's a good idea to do some testing on an expendable copy of a file first. | |
40 For example: If you use autocommands to decompress a file when starting to | |
41 edit it, make sure that the autocommands for compressing when writing work | |
42 correctly. | |
43 - Be prepared for an error halfway through (e.g., disk full). Vim will mostly | |
44 be able to undo the changes to the buffer, but you may have to clean up the | |
45 changes to other files by hand (e.g., compress a file that has been | |
46 decompressed). | |
47 - If the BufRead* events allow you to edit a compressed file, the FileRead* | |
48 events should do the same (this makes recovery possible in some rare cases). | |
49 It's a good idea to use the same autocommands for the File* and Buf* events | |
50 when possible. | |
51 | |
52 ============================================================================== | |
53 2. Defining autocommands *autocmd-define* | |
54 | |
55 Note: The ":autocmd" command cannot be followed by another command, since any | |
56 '|' is considered part of the command. | |
57 | |
58 *:au* *:autocmd* | |
59 :au[tocmd] [group] {event} {pat} [nested] {cmd} | |
60 Add {cmd} to the list of commands that Vim will | |
61 execute automatically on {event} for a file matching | |

65 they were given. See |autocmd-nested| for [nested]. |
7 | 66 |
40 | 67 The special pattern <buffer> or <buffer=N> defines a buffer-local autocommand. |
68 See |autocmd-buflocal|. | |
69 | |
7 | 70 Note that special characters (e.g., "%", "<cword>") in the ":autocmd" |
71 arguments are not expanded when the autocommand is defined. These will be | |
72 expanded when the Event is recognized, and the {cmd} is executed. The only | |
73 exception is that "<sfile>" is expanded when the autocmd is defined. Example: | |
74 > | |
75 :au BufNewFile,BufRead *.html so <sfile>:h/html.vim | |
76 | |
77 Here Vim expands <sfile> to the name of the file containing this line. | |
78 | |
79 When your .vimrc file is sourced twice, the autocommands will appear twice. | |
80 To avoid this, put this command in your .vimrc file, before defining | |
81 autocommands: > | |
82 | |
83 :autocmd! " Remove ALL autocommands for the current group. | |
84 | |
85 If you don't want to remove all autocommands, you can instead use a variable | |
86 to ensure that Vim includes the autocommands only once: > | |
87 | |
88 :if !exists("autocommands_loaded") | |
89 : let autocommands_loaded = 1 | |
90 : au ... | |
91 :endif | |
92 | |
93 When the [group] argument is not given, Vim uses the current group (as defined | |
94 with ":augroup"); otherwise, Vim uses the group defined with [group]. Note | |
95 that [group] must have been defined before. You cannot define a new group | |
96 with ":au group ..."; use ":augroup" for that. | |
97 | |
98 While testing autocommands, you might find the 'verbose' option to be useful: > | |
99 :set verbose=9 | |
100 This setting makes Vim echo the autocommands as it executes them. | |
101 | |
102 When defining an autocommand in a script, it will be able to call functions | |
103 local to the script and use mappings local to the script. When the event is | |
104 triggered and the command executed, it will run in the context of the script | |
105 it was defined in. This matters if |<SID>| is used in a command. | |
106 | |
1621 | 107 When executing the commands, the message from one command overwrites a |
7 | 108 previous message. This is different from when executing the commands |
109 manually. Mostly the screen will not scroll up, thus there is no hit-enter | |
110 prompt. When one command outputs two messages this can happen anyway. | |
111 | |
112 ============================================================================== | |
113 3. Removing autocommands *autocmd-remove* | |
114 | |
115 :au[tocmd]! [group] {event} {pat} [nested] {cmd} | |
116 Remove all autocommands associated with {event} and | |
117 {pat}, and add the command {cmd}. See | |
118 |autocmd-nested| for [nested]. | |
119 | |
120 :au[tocmd]! [group] {event} {pat} | |
121 Remove all autocommands associated with {event} and | |
122 {pat}. | |
123 | |
124 :au[tocmd]! [group] * {pat} | |
125 Remove all autocommands associated with {pat} for all | |
126 events. | |
127 | |
128 :au[tocmd]! [group] {event} | |
129 Remove ALL autocommands for {event}. | |
130 | |
131 :au[tocmd]! [group] Remove ALL autocommands. | |
132 | |
133 When the [group] argument is not given, Vim uses the current group (as defined | |
134 with ":augroup"); otherwise, Vim uses the group defined with [group]. | |
135 | |
136 ============================================================================== | |
137 4. Listing autocommands *autocmd-list* | |
138 | |
139 :au[tocmd] [group] {event} {pat} | |
140 Show the autocommands associated with {event} and | |
141 {pat}. | |
142 | |
143 :au[tocmd] [group] * {pat} | |
144 Show the autocommands associated with {pat} for all | |
145 events. | |
146 | |
147 :au[tocmd] [group] {event} | |
148 Show all autocommands for {event}. | |
149 | |
150 :au[tocmd] [group] Show all autocommands. | |
151 | |
152 If you provide the [group] argument, Vim lists only the autocommands for | |
153 [group]; otherwise, Vim lists the autocommands for ALL groups. Note that this | |
154 argument behavior differs from that for defining and removing autocommands. | |
155 | |
40 | 156 In order to list buffer-local autocommands, use a pattern in the form <buffer> |
157 or <buffer=N>. See |autocmd-buflocal|. | |
158 | |
500 | 159 *:autocmd-verbose* |
160 When 'verbose' is non-zero, listing an autocommand will also display where it | |
161 was last defined. Example: > | |
162 | |
163 :verbose autocmd BufEnter | |
164 FileExplorer BufEnter | |
856 | 165 * call s:LocalBrowse(expand("<amatch>")) |
500 | 166 Last set from /usr/share/vim/vim-7.0/plugin/NetrwPlugin.vim |
167 < | |
168 See |:verbose-cmd| for more information. | |
169 | |
7 | 170 ============================================================================== |
171 5. Events *autocmd-events* *E215* *E216* | |
172 | |
579 | 173 You can specify a comma-separated list of event names. No white space can be |
174 used in this list. The command applies to all the events in the list. | |
175 | |
176 For READING FILES there are four kinds of events possible: | |
177 BufNewFile starting to edit a non-existent file | |
178 BufReadPre BufReadPost starting to edit an existing file | |
179 FilterReadPre FilterReadPost read the temp file with filter output | |
180 FileReadPre FileReadPost any other file read | |
181 Vim uses only one of these four kinds when reading a file. The "Pre" and | |
182 "Post" events are both triggered, before and after reading the file. | |
183 | |
184 Note that the autocommands for the *ReadPre events and all the Filter events | |
185 are not allowed to change the current buffer (you will get an error message if | |
186 this happens). This is to prevent the file to be read into the wrong buffer. | |
187 | |
188 Note that the 'modified' flag is reset AFTER executing the BufReadPost | |
189 and BufNewFile autocommands. But when the 'modified' option was set by the | |
190 autocommands, this doesn't happen. | |
191 | |
192 You can use the 'eventignore' option to ignore a number of events or all | |
193 events. | |
7 | 194 *autocommand-events* *{event}* |
195 Vim recognizes the following events. Vim ignores the case of event names | |
196 (e.g., you can use "BUFread" or "bufread" instead of "BufRead"). | |
197 | |

324 | |
325 The alphabetical list of autocommand events: *autocmd-events-abc* | |
326 | |
327 *BufCreate* *BufAdd* | |
328 BufAdd or BufCreate Just after creating a new buffer which is | |
329 added to the buffer list, or adding a buffer | |
330 to the buffer list. | |
331 Also used just after a buffer in the buffer | |
332 list has been renamed. | |
333 The BufCreate event is for historic reasons. | |
334 NOTE: When this autocommand is executed, the | |
335 current buffer "%" may be different from the | |
336 buffer being created "<afile>". | |
337 *BufDelete* | |
338 BufDelete Before deleting a buffer from the buffer list. | |
339 The BufUnload may be called first (if the | |
340 buffer was loaded). | |
341 Also used just before a buffer in the buffer | |
342 list is renamed. | |
343 NOTE: When this autocommand is executed, the | |
344 current buffer "%" may be different from the | |
1621 | 345 buffer being deleted "<afile>" and "<abuf>". |
1919 | 346 Don't change to another buffer, it will cause |
347 problems. | |
579 | 348 *BufEnter* |
349 BufEnter After entering a buffer. Useful for setting | |
350 options for a file type. Also executed when | |
351 starting to edit a buffer, after the | |
352 BufReadPost autocommands. | |
353 *BufFilePost* | |
354 BufFilePost After changing the name of the current buffer | |
355 with the ":file" or ":saveas" command. | |
625 | 356 *BufFilePre* |
579 | 357 BufFilePre Before changing the name of the current buffer |
358 with the ":file" or ":saveas" command. | |
359 *BufHidden* | |
360 BufHidden Just after a buffer has become hidden. That | |
361 is, when there are no longer windows that show | |
362 the buffer, but the buffer is not unloaded or | |
363 deleted. Not used for ":qa" or ":q" when | |
364 exiting Vim. | |
365 NOTE: When this autocommand is executed, the | |
366 current buffer "%" may be different from the | |
367 buffer being unloaded "<afile>". | |
368 *BufLeave* | |
369 BufLeave Before leaving to another buffer. Also when | |
370 leaving or closing the current window and the | |
371 new current window is not for the same buffer. | |
372 Not used for ":qa" or ":q" when exiting Vim. | |
373 *BufNew* | |
374 BufNew Just after creating a new buffer. Also used | |
375 just after a buffer has been renamed. When | |
376 the buffer is added to the buffer list BufAdd | |
377 will be triggered too. | |
378 NOTE: When this autocommand is executed, the | |
379 current buffer "%" may be different from the | |
380 buffer being created "<afile>". | |
7 | 381 *BufNewFile* |
382 BufNewFile When starting to edit a file that doesn't | |
383 exist. Can be used to read in a skeleton | |
384 file. | |
385 *BufRead* *BufReadPost* | |
386 BufRead or BufReadPost When starting to edit a new buffer, after | |
387 reading the file into the buffer, before | |
388 executing the modelines. See |BufWinEnter| | |
389 for when you need to do something after | |
390 processing the modelines. | |
391 This does NOT work for ":r file". Not used | |
392 when the file doesn't exist. Also used after | |
393 successfully recovering a file. | |
3682 | 394 Also triggered for the filetypedetect group |
395 when executing ":filetype detect" and when | |
396 writing an unnamed buffer in a way that the | |
397 buffer gets a name. | |
625 | 398 *BufReadCmd* |
7 | 399 BufReadCmd Before starting to edit a new buffer. Should |
400 read the file into the buffer. |Cmd-event| | |
625 | 401 *BufReadPre* *E200* *E201* |
579 | 402 BufReadPre When starting to edit a new buffer, before |
403 reading the file into the buffer. Not used | |
404 if the file doesn't exist. | |
405 *BufUnload* | |
406 BufUnload Before unloading a buffer. This is when the | |
407 text in the buffer is going to be freed. This | |
408 may be after a BufWritePost and before a | |
409 BufDelete. Also used for all buffers that are | |
410 loaded when Vim is going to exit. | |
411 NOTE: When this autocommand is executed, the | |
412 current buffer "%" may be different from the | |
413 buffer being unloaded "<afile>". | |
1919 | 414 Don't change to another buffer, it will cause |
415 problems. | |

417 event is not triggered. |
579 | 418 *BufWinEnter* |
419 BufWinEnter After a buffer is displayed in a window. This | |
420 can be when the buffer is loaded (after | |
1621 | 421 processing the modelines) or when a hidden |
579 | 422 buffer is displayed in a window (and is no |
1621 | 423 longer hidden). |
424 Does not happen for |:split| without | |
425 arguments, since you keep editing the same | |
426 buffer, or ":split" with a file that's already | |
1668 | 427 open in a window, because it re-uses an |
428 existing buffer. But it does happen for a | |
429 ":split" with the name of the current buffer, | |
430 since it reloads that buffer. | |
579 | 431 *BufWinLeave* |
432 BufWinLeave Before a buffer is removed from a window. | |
433 Not when it's still visible in another window. | |
434 Also triggered when exiting. It's triggered | |
435 before BufUnload or BufHidden. | |
436 NOTE: When this autocommand is executed, the | |
437 current buffer "%" may be different from the | |

440 event is not triggered. |
579 | 441 *BufWipeout* |
442 BufWipeout Before completely deleting a buffer. The | |
443 BufUnload and BufDelete events may be called | |
444 first (if the buffer was loaded and was in the | |
445 buffer list). Also used just before a buffer | |
446 is renamed (also when it's not in the buffer | |
447 list). | |
448 NOTE: When this autocommand is executed, the | |
449 current buffer "%" may be different from the | |
450 buffer being deleted "<afile>". | |
1919 | 451 Don't change to another buffer, it will cause |
452 problems. | |

455 *BufWriteCmd* | |
456 BufWriteCmd Before writing the whole buffer to a file. | |
457 Should do the writing of the file and reset | |
39 | 458 'modified' if successful, unless '+' is in |
459 'cpo' and writing to another file |cpo-+|. | |
460 The buffer contents should not be changed. | |
3082 | 461 When the command resets 'modified' the undo |
462 information is adjusted to mark older undo | |
463 states as 'modified', like |:write| does. | |
39 | 464 |Cmd-event| |
579 | 465 *BufWritePost* |
466 BufWritePost After writing the whole buffer to a file | |
467 (should undo the commands for BufWritePre). | |
468 *CmdwinEnter* | |
469 CmdwinEnter After entering the command-line window. | |
470 Useful for setting options specifically for | |
471 this special type of window. This is | |
472 triggered _instead_ of BufEnter and WinEnter. | |
473 <afile> is set to a single character, | |
474 indicating the type of command-line. | |
475 |cmdwin-char| | |
476 *CmdwinLeave* | |
477 CmdwinLeave Before leaving the command-line window. | |
478 Useful to clean up any global setting done | |
479 with CmdwinEnter. This is triggered _instead_ | |
480 of BufLeave and WinLeave. | |

490 name. | |
491 | |
661 | 492 |
3682 | 493 *CompleteDone* |

501 until the user has pressed a key (i.e. doesn't | |
502 fire every 'updatetime' ms if you leave Vim to | |
503 make some coffee. :) See |CursorHold-example| | |
504 for previewing tags. | |
505 This event is only triggered in Normal mode. | |
1154 | 506 It is not triggered when waiting for a command |
507 argument to be typed, or a movement after an | |
508 operator. | |
610 | 509 While recording the CursorHold event is not |
510 triggered. |q| | |
579 | 511 Note: Interactive commands cannot be used for |
512 this event. There is no hit-enter prompt, | |
513 the screen is updated directly (when needed). | |
514 Note: In the future there will probably be | |
515 another option to set the time. | |
516 Hint: to force an update of the status lines | |
517 use: > | |

527 has been changed, e.g., with "x", "rx" or "p". | |
661 | 528 Not triggered when there is typeahead or when |
529 an operator is pending. | |
667 | 530 For an example see |match-parens|. |
4264 | 531 Careful: This is triggered very often, don't |
532 do anything that the user does not expect or | |
533 that is slow. | |
661 | 534 *CursorMovedI* |
535 CursorMovedI After the cursor was moved in Insert mode. | |
3082 | 536 Not triggered when the popup menu is visible. |
661 | 537 Otherwise the same as CursorMoved. |
579 | 538 *EncodingChanged* |

540 changed. Useful to set up fonts, for example. | |
7 | 541 *FileAppendCmd* |

555 This event is triggered when making the first | |
556 change in a buffer or the first change after | |
823 | 557 'readonly' was set, just before the change is |
558 applied to the text. | |
579 | 559 WARNING: If the autocommand moves the cursor |
560 the effect of the change is undefined. | |
819 | 561 *E788* |

575 command, but also with a |:checktime| command | |
179 | 576 or when Gvim regains input focus. |
7 | 577 This autocommand is triggered for each changed |
578 file. It is not used when 'autoread' is set | |
579 and the buffer was not changed. If a | |
580 FileChangedShell autocommand is present the | |
581 warning message and prompt is not given. | |
179 | 582 The |v:fcs_reason| variable is set to indicate |
583 what happened and |v:fcs_choice| can be used | |
584 to tell Vim what to do next. | |
7 | 585 NOTE: When this autocommand is executed, the |
586 current buffer "%" may be different from the | |
587 buffer that was changed "<afile>". | |

590 buffer. *E246* *E811* |
7 | 591 NOTE: This event never nests, to avoid an |
592 endless loop. This means that while executing | |

760 the reply was sent, and <afile> is the actual | |
761 reply string. | |

806 edited. |v:swapcommand| may contain a command | |
807 to be executed in the opened file. | |
808 The commands should set the |v:swapchoice| | |
809 variable to a string with one character to | |
810 tell Vim what should be done next: | |
579 | 811 'o' open read-only |
812 'e' edit the file anyway | |
813 'r' recover | |
814 'd' delete the swap file | |

860 *TextChangedI* | |
861 TextChangedI After a change was made to the text in the | |

863 Not triggered when the popup menu is visible. | |
864 Otherwise the same as TextChanged. | |
579 | 865 *User* |
866 User Never executed automatically. To be used for | |
867 autocommands that are only executed with | |
868 ":doautocmd". | |
869 *UserGettingBored* | |

579 | 872 *VimEnter* |
873 VimEnter After doing all the startup stuff, including | |
874 loading .vimrc files, executing the "-c cmd" | |
875 arguments, creating all windows and loading | |
876 the buffers in them. | |
877 *VimLeave* | |

916 6. Patterns *autocmd-patterns* *{pat}* | |
917 | |
918 The file pattern {pat} is tested for a match against the file name in one of | |
919 two ways: | |
920 1. When there is no '/' in the pattern, Vim checks for a match against only | |
921 the tail part of the file name (without its leading directory path). | |

|
924 it to a full path and resolving symbolic links). |
7 | 925 |
40 | 926 The special pattern <buffer> or <buffer=N> is used for buffer-local |
927 autocommands |autocmd-buflocal|. This pattern is not matched against the name | |
928 of a buffer. | |
929 | |
7 | 930 Examples: > |
931 :autocmd BufRead *.txt set et | |
932 Set the 'et' option for all text files. > | |
933 | |
934 :autocmd BufRead /vim/src/*.c set cindent | |
935 Set the 'cindent' option for C files in the /vim/src directory. > | |
936 | |
937 :autocmd BufRead /tmp/*.c set ts=5 | |
938 If you have a link from "/tmp/test.c" to "/home/nobody/vim/src/test.c", and | |
939 you start editing "/tmp/test.c", this autocommand will match. | |
940 | |
941 Note: To match part of a path, but not from the root directory, use a '*' as | |
942 the first character. Example: > | |
943 :autocmd BufRead */doc/*.txt set tw=78 | |
944 This autocommand will for example be executed for "/tmp/doc/xx.txt" and | |
945 "/usr/home/piet/doc/yy.txt". The number of directories does not matter here. | |
946 | |
947 | |
948 The file name that the pattern is matched against is after expanding | |
1621 | 949 wildcards. Thus if you issue this command: > |
7 | 950 :e $ROOTDIR/main.$EXT |
951 The argument is first expanded to: > | |
952 /usr/root/main.py | |
953 Before it's matched with the pattern of the autocommand. Careful with this | |
954 when using events like FileReadCmd, the value of <amatch> may not be what you | |
955 expect. | |
956 | |
957 | |
958 Environment variables can be used in a pattern: > | |
959 :autocmd BufRead $VIMRUNTIME/doc/*.txt set expandtab | |
960 And ~ can be used for the home directory (if $HOME is defined): > | |
961 :autocmd BufWritePost ~/.vimrc so ~/.vimrc | |
962 :autocmd BufRead ~archive/* set readonly | |
963 The environment variable is expanded when the autocommand is defined, not when | |
964 the autocommand is executed. This is different from the command! | |
965 | |
966 *file-pattern* | |
967 The pattern is interpreted like mostly used in file names: | |
5294 | 968 * matches any sequence of characters; Unusual: includes path |
5277 | 969 separators |
7 | 970 ? matches any single character |
971 \? matches a '?' | |
972 . matches a '.' | |
973 ~ matches a '~' | |
974 , separates patterns | |
975 \, matches a ',' | |
976 { } like \( \) in a |pattern| | |
977 , inside { }: like \| in a |pattern| | |

980 \\\{n,m\} like \{n,m} in a |pattern| |
7 | 981 \ special meaning like in a |pattern| |
982 [ch] matches 'c' or 'h' | |
983 [^ch] match any character but 'c' and 'h' | |
984 | |
985 Note that for all systems the '/' character is used for path separator (even | |
986 MS-DOS and OS/2). This was done because the backslash is difficult to use | |
987 in a pattern and to make the autocommands portable across different systems. | |
988 | |
40 | 989 *autocmd-changes* |
7 | 990 Matching with the pattern is done when an event is triggered. Changing the |
991 buffer name in one of the autocommands, or even deleting the buffer, does not | |
992 change which autocommands will be executed. Example: > | |
993 | |
994 au BufEnter *.foo bdel | |
995 au BufEnter *.foo set modified | |
996 | |
997 This will delete the current buffer and then set 'modified' in what has become | |
998 the current buffer instead. Vim doesn't take into account that "*.foo" | |
999 doesn't match with that buffer name. It matches "*.foo" with the name of the | |
1000 buffer at the moment the event was triggered. | |
1001 | |
40 | 1002 However, buffer-local autocommands will not be executed for a buffer that has |
1003 been wiped out with |:bwipe|. After deleting the buffer with |:bdel| the | |
1004 buffer actually still exists (it becomes unlisted), thus the autocommands are | |
1005 still executed. | |
1006 | |
7 | 1007 ============================================================================== |
856 | 1008 7. Buffer-local autocommands *autocmd-buflocal* *autocmd-buffer-local* |
1009 *<buffer=N>* *<buffer=abuf>* *E680* | |
40 | 1010 |
1011 Buffer-local autocommands are attached to a specific buffer. They are useful | |
1012 if the buffer does not have a name and when the name does not match a specific | |
1013 pattern. But it also means they must be explicitly added to each buffer. | |
1014 | |
1015 Instead of a pattern buffer-local autocommands use one of these forms: | |
1016 <buffer> current buffer | |
1017 <buffer=99> buffer number 99 | |
1018 <buffer=abuf> using <abuf> (only when executing autocommands) | |
1019 |<abuf>| | |
1020 | |
1021 Examples: > | |
1022 :au CursorHold <buffer> echo 'hold' | |
1023 :au CursorHold <buffer=33> echo 'hold' | |
1024 :au CursorHold <buffer=abuf> echo 'hold' | |
1025 | |
1026 All the commands for autocommands also work with buffer-local autocommands, | |
1027 simply use the special string instead of the pattern. Examples: > | |
856 | 1028 :au! * <buffer> " remove buffer-local autocommands for |
1029 " current buffer | |
1030 :au! * <buffer=33> " remove buffer-local autocommands for | |
1031 " buffer #33 | |
1621 | 1032 :bufdo :au! CursorHold <buffer> " remove autocmd for given event for all |
856 | 1033 " buffers |
1034 :au * <buffer> " list buffer-local autocommands for | |
1035 " current buffer | |
40 | 1036 |
1037 Note that when an autocommand is defined for the current buffer, it is stored | |
1038 with the buffer number. Thus it uses the form "<buffer=12>", where 12 is the | |
1039 number of the current buffer. You will see this when listing autocommands, | |
1040 for example. | |
1041 | |
1042 To test for presence of buffer-local autocommands use the |exists()| function | |
1043 as follows: > | |
1044 :if exists("#CursorHold#<buffer=12>") | ... | endif | |
1045 :if exists("#CursorHold#<buffer>") | ... | endif " for current buffer | |
1046 | |
1047 When a buffer is wiped out its buffer-local autocommands are also gone, of | |
1048 course. Note that when deleting a buffer, e.g., with ":bdel", it is only | |
1049 unlisted, the autocommands are still present. In order to see the removal of | |
1050 buffer-local autocommands: > | |
1051 :set verbose=6 | |
1052 | |
1053 It is not possible to define buffer-local autocommands for a non-existent | |
1054 buffer. | |
1055 | |
1056 ============================================================================== | |
1057 8. Groups *autocmd-groups* | |
7 | 1058 |
1059 Autocommands can be put together in a group. This is useful for removing or | |
1060 executing a group of autocommands. For example, all the autocommands for | |
1061 syntax highlighting are put in the "highlight" group, to be able to execute | |
1062 ":doautoall highlight BufRead" when the GUI starts. | |
1063 | |
1064 When no specific group is selected, Vim uses the default group. The default | |
1065 group does not have a name. You cannot execute the autocommands from the | |
1066 default group separately; you can execute them only by executing autocommands | |
1067 for all groups. | |
1068 | |
1069 Normally, when executing autocommands automatically, Vim uses the autocommands | |
1070 for all groups. The group only matters when executing autocommands with | |
1071 ":doautocmd" or ":doautoall", or when defining or deleting autocommands. | |
1072 | |
1073 The group name can contain any characters except white space. The group name | |
1074 "end" is reserved (also in uppercase). | |
1075 | |
1076 The group name is case sensitive. Note that this is different from the event | |
1077 name! | |
1078 | |
1079 *:aug* *:augroup* | |
1080 :aug[roup] {name} Define the autocmd group name for the | |
1081 following ":autocmd" commands. The name "end" | |
1082 or "END" selects the default group. | |
1083 | |
1084 *:augroup-delete* *E367* | |
1085 :aug[roup]! {name} Delete the autocmd group {name}. Don't use | |
1086 this if there is still an autocommand using | |
1087 this group! This is not checked. | |
1088 | |
1089 To enter autocommands for a specific group, use this method: | |
1090 1. Select the group with ":augroup {name}". | |
1091 2. Delete any old autocommands with ":au!". | |
1092 3. Define the autocommands. | |
1093 4. Go back to the default group with "augroup END". | |
1094 | |
1095 Example: > | |
1096 :augroup uncompress | |
1097 : au! | |
1098 : au BufEnter *.gz %!gunzip | |
1099 :augroup END | |
1100 | |
1101 This prevents having the autocommands defined twice (e.g., after sourcing the | |
1102 .vimrc file again). | |
1103 | |
1104 ============================================================================== | |
40 | 1105 9. Executing autocommands *autocmd-execute* |
7 | 1106 |
1107 Vim can also execute Autocommands non-automatically. This is useful if you | |
1108 have changed autocommands, or when Vim has executed the wrong autocommands | |
1109 (e.g., the file pattern match was wrong). | |
1110 | |
1111 Note that the 'eventignore' option applies here too. Events listed in this | |
1112 option will not cause any commands to be executed. | |
1113 | |
1114 *:do* *:doau* *:doautocmd* *E217* | |
3356 | 1115 :do[autocmd] [<nomodeline>] [group] {event} [fname] |
7 | 1116 Apply the autocommands matching [fname] (default: |
1117 current file name) for {event} to the current buffer. | |
1118 You can use this when the current file name does not | |
1119 match the right pattern, after changing settings, or | |
1120 to execute autocommands for a certain event. | |
1121 It's possible to use this inside an autocommand too, | |
1122 so you can base the autocommands for one extension on | |
1123 another extension. Example: > | |
3224 | 1124 :au BufEnter *.cpp so ~/.vimrc_cpp |
1125 :au BufEnter *.cpp doau BufEnter x.c | |
7 | 1126 < Be careful to avoid endless loops. See |
1127 |autocmd-nested|. | |
1128 | |
1129 When the [group] argument is not given, Vim executes | |
1130 the autocommands for all groups. When the [group] | |
1131 argument is included, Vim executes only the matching | |
1132 autocommands for that group. Note: if you use an | |
1133 undefined group name, Vim gives you an error message. | |
3350 | 1134 *<nomodeline>* |
1135 After applying the autocommands the modelines are | |
1136 processed, so that their settings overrule the | |
1137 settings from autocommands, like what happens when | |
1138 editing a file. This is skipped when the <nomodeline> | |
1139 argument is present. You probably want to use | |
1140 <nomodeline> for events that are not used when loading | |
1141 a buffer, such as |User|. | |
7 | 1142 |
1143 *:doautoa* *:doautoall* | |
3342 | 1144 :doautoa[ll] [<nomodeline>] [group] {event} [fname] |
7 | 1145 Like ":doautocmd", but apply the autocommands to each |

|
1146 loaded buffer. Note that [fname] is used to select |
7 | 1147 the autocommands, not the buffers to which they are |
1148 applied. | |
1149 Careful: Don't use this for autocommands that delete a | |
1150 buffer, change to another buffer or change the | |
1151 contents of a buffer; the result is unpredictable. | |
1152 This command is intended for autocommands that set | |
1153 options, change highlighting, and things like that. | |
1154 | |
1155 ============================================================================== | |
40 | 1156 10. Using autocommands *autocmd-use* |
7 | 1157 |
1158 For WRITING FILES there are four possible sets of events. Vim uses only one | |
1159 of these sets for a write command: | |
1160 | |
1161 BufWriteCmd BufWritePre BufWritePost writing the whole buffer | |
1162 FilterWritePre FilterWritePost writing to filter temp file | |
1163 FileAppendCmd FileAppendPre FileAppendPost appending to a file | |
1164 FileWriteCmd FileWritePre FileWritePost any other file write | |
1165 | |
1166 When there is a matching "*Cmd" autocommand, it is assumed it will do the | |
1167 writing. No further writing is done and the other events are not triggered. | |
1168 |Cmd-event| | |
1169 | |
1170 Note that the *WritePost commands should undo any changes to the buffer that | |
1171 were caused by the *WritePre commands; otherwise, writing the file will have | |
1172 the side effect of changing the buffer. | |
1173 | |
1174 Before executing the autocommands, the buffer from which the lines are to be | |
1175 written temporarily becomes the current buffer. Unless the autocommands | |
1176 change the current buffer or delete the previously current buffer, the | |
1177 previously current buffer is made the current buffer again. | |
1178 | |
1179 The *WritePre and *AppendPre autocommands must not delete the buffer from | |
1180 which the lines are to be written. | |
1181 | |
1182 The '[ and '] marks have a special position: | |
1183 - Before the *ReadPre event the '[ mark is set to the line just above where | |
1184 the new lines will be inserted. | |
1185 - Before the *ReadPost event the '[ mark is set to the first line that was | |
1186 just read, the '] mark to the last line. | |
26 | 1187 - Before executing the *WriteCmd, *WritePre and *AppendPre autocommands the '[ |
1188 mark is set to the first line that will be written, the '] mark to the last | |
1189 line. | |
7 | 1190 Careful: '[ and '] change when using commands that change the buffer. |
1191 | |
1192 In commands which expect a file name, you can use "<afile>" for the file name | |
1193 that is being read |:<afile>| (you can also use "%" for the current file | |
1194 name). "<abuf>" can be used for the buffer number of the currently effective | |
1195 buffer. This also works for buffers that doesn't have a name. But it doesn't | |
1196 work for files without a buffer (e.g., with ":r file"). | |
1197 | |
1198 *gzip-example* | |
1199 Examples for reading and writing compressed files: > | |
1200 :augroup gzip | |
1201 : autocmd! | |
1202 : autocmd BufReadPre,FileReadPre *.gz set bin | |
1203 : autocmd BufReadPost,FileReadPost *.gz '[,']!gunzip | |
1204 : autocmd BufReadPost,FileReadPost *.gz set nobin | |
1205 : autocmd BufReadPost,FileReadPost *.gz execute ":doautocmd BufReadPost " . expand("%:r") | |
1206 : autocmd BufWritePost,FileWritePost *.gz !mv <afile> <afile>:r | |
1207 : autocmd BufWritePost,FileWritePost *.gz !gzip <afile>:r | |
1208 | |
1209 : autocmd FileAppendPre *.gz !gunzip <afile> | |
1210 : autocmd FileAppendPre *.gz !mv <afile>:r <afile> | |
1211 : autocmd FileAppendPost *.gz !mv <afile> <afile>:r | |
1212 : autocmd FileAppendPost *.gz !gzip <afile>:r | |
1213 :augroup END | |
1214 | |
1215 The "gzip" group is used to be able to delete any existing autocommands with | |
1216 ":autocmd!", for when the file is sourced twice. | |
1217 | |
1218 ("<afile>:r" is the file name without the extension, see |:_%:|) | |
1219 | |
1220 The commands executed for the BufNewFile, BufRead/BufReadPost, BufWritePost, | |
1221 FileAppendPost and VimLeave events do not set or reset the changed flag of the | |
1222 buffer. When you decompress the buffer with the BufReadPost autocommands, you | |
1223 can still exit with ":q". When you use ":undo" in BufWritePost to undo the | |
1224 changes made by BufWritePre commands, you can still do ":q" (this also makes | |
1225 "ZZ" work). If you do want the buffer to be marked as modified, set the | |
1226 'modified' option. | |
1227 | |
1228 To execute Normal mode commands from an autocommand, use the ":normal" | |
1229 command. Use with care! If the Normal mode command is not finished, the user | |
1230 needs to type characters (e.g., after ":normal m" you need to type a mark | |
1231 name). | |
1232 | |
1233 If you want the buffer to be unmodified after changing it, reset the | |
1234 'modified' option. This makes it possible to exit the buffer with ":q" | |
1235 instead of ":q!". | |
1236 | |
1237 *autocmd-nested* *E218* | |
1238 By default, autocommands do not nest. If you use ":e" or ":w" in an | |
1239 autocommand, Vim does not execute the BufRead and BufWrite autocommands for | |
1240 those commands. If you do want this, use the "nested" flag for those commands | |
1241 in which you want nesting. For example: > | |
1242 :autocmd FileChangedShell *.c nested e! | |
1243 The nesting is limited to 10 levels to get out of recursive loops. | |
1244 | |
1245 It's possible to use the ":au" command in an autocommand. This can be a | |
1246 self-modifying command! This can be useful for an autocommand that should | |
1247 execute only once. | |
1248 | |
590 | 1249 If you want to skip autocommands for one command, use the |:noautocmd| command |
1250 modifier or the 'eventignore' option. | |
7 | 1251 |
1252 Note: When reading a file (with ":read file" or with a filter command) and the | |
1253 last line in the file does not have an <EOL>, Vim remembers this. At the next | |
1254 write (with ":write file" or with a filter command), if the same line is | |
1255 written again as the last line in a file AND 'binary' is set, Vim does not | |
1256 supply an <EOL>. This makes a filter command on the just read lines write the | |
1257 same file as was read, and makes a write command on just filtered lines write | |
1258 the same file as was read from the filter. For example, another way to write | |
1259 a compressed file: > | |
1260 | |
1261 :autocmd FileWritePre *.gz set bin|'[,']!gzip | |
1262 :autocmd FileWritePost *.gz undo|set nobin | |
1263 < | |
1264 *autocommand-pattern* | |
1265 You can specify multiple patterns, separated by commas. Here are some | |
1266 examples: > | |
1267 | |
1268 :autocmd BufRead * set tw=79 nocin ic infercase fo=2croq | |
1269 :autocmd BufRead .letter set tw=72 fo=2tcrq | |
1270 :autocmd BufEnter .letter set dict=/usr/lib/dict/words | |
1271 :autocmd BufLeave .letter set dict= | |
1272 :autocmd BufRead,BufNewFile *.c,*.h set tw=0 cin noic | |
1273 :autocmd BufEnter *.c,*.h abbr FOR for (i = 0; i < 3; ++i)<CR>{<CR>}<Esc>O | |
1274 :autocmd BufLeave *.c,*.h unabbr FOR | |
1275 | |
1276 For makefiles (makefile, Makefile, imakefile, makefile.unix, etc.): > | |
1277 | |
1278 :autocmd BufEnter ?akefile* set include=^s\=include | |
1279 :autocmd BufLeave ?akefile* set include& | |
1280 | |
1281 To always start editing C files at the first function: > | |
1282 | |
1283 :autocmd BufRead *.c,*.h 1;/^{ | |
1284 | |
1285 Without the "1;" above, the search would start from wherever the file was | |
1286 entered, rather than from the start of the file. | |
1287 | |
1288 *skeleton* *template* | |
1289 To read a skeleton (template) file when opening a new file: > | |
1290 | |
1291 :autocmd BufNewFile *.c 0r ~/vim/skeleton.c | |
1292 :autocmd BufNewFile *.h 0r ~/vim/skeleton.h | |
1293 :autocmd BufNewFile *.java 0r ~/vim/skeleton.java | |
1294 | |
1295 To insert the current date and time in a *.html file when writing it: > | |
1296 | |
1297 :autocmd BufWritePre,FileWritePre *.html ks|call LastMod()|'s | |
1298 :fun LastMod() | |
1299 : if line("$") > 20 | |
1300 : let l = 20 | |
1301 : else | |
1302 : let l = line("$") | |
1303 : endif | |
1304 : exe "1," . l . "g/Last modified: /s/Last modified: .*/Last modified: " . | |
1305 : \ strftime("%Y %b %d") | |
1306 :endfun | |
1307 | |
1308 You need to have a line "Last modified: <date time>" in the first 20 lines | |
1309 of the file for this to work. Vim replaces <date time> (and anything in the | |
1310 same line after it) with the current date and time. Explanation: | |
1311 ks mark current position with mark 's' | |
1312 call LastMod() call the LastMod() function to do the work | |
1313 's return the cursor to the old position | |
1314 The LastMod() function checks if the file is shorter than 20 lines, and then | |
1315 uses the ":g" command to find lines that contain "Last modified: ". For those | |
1316 lines the ":s" command is executed to replace the existing date with the | |
1317 current one. The ":execute" command is used to be able to use an expression | |
1318 for the ":g" and ":s" commands. The date is obtained with the strftime() | |
1319 function. You can change its argument to get another date string. | |
1320 | |
1321 When entering :autocmd on the command-line, completion of events and command | |
1322 names may be done (with <Tab>, CTRL-D, etc.) where appropriate. | |
1323 | |
1324 Vim executes all matching autocommands in the order that you specify them. | |
1325 It is recommended that your first autocommand be used for all files by using | |
1326 "*" as the file pattern. This means that you can define defaults you like | |
1327 here for any settings, and if there is another matching autocommand it will | |
1328 override these. But if there is no other matching autocommand, then at least | |
1329 your default settings are recovered (if entering this file from another for | |
1330 which autocommands did match). Note that "*" will also match files starting | |
1331 with ".", unlike Unix shells. | |
1332 | |
1333 *autocmd-searchpat* | |
1334 Autocommands do not change the current search patterns. Vim saves the current | |
1335 search patterns before executing autocommands then restores them after the | |
1336 autocommands finish. This means that autocommands do not affect the strings | |
1337 highlighted with the 'hlsearch' option. Within autocommands, you can still | |
1338 use search patterns normally, e.g., with the "n" command. | |
1339 If you want an autocommand to set the search pattern, such that it is used | |
1340 after the autocommand finishes, use the ":let @/ =" command. | |
1341 The search-highlighting cannot be switched off with ":nohlsearch" in an | |
1342 autocommand. Use the 'h' flag in the 'viminfo' option to disable search- | |
1343 highlighting when starting Vim. | |
1344 | |
1345 *Cmd-event* | |
1346 When using one of the "*Cmd" events, the matching autocommands are expected to | |
1061 | 1347 do the file reading, writing or sourcing. This can be used when working with |
1348 a special kind of file, for example on a remote system. | |
7 | 1349 CAREFUL: If you use these events in a wrong way, it may have the effect of |
1350 making it impossible to read or write the matching files! Make sure you test | |
1351 your autocommands properly. Best is to use a pattern that will never match a | |
1352 normal file name, for example "ftp://*". | |
1353 | |
1354 When defining a BufReadCmd it will be difficult for Vim to recover a crashed | |
1355 editing session. When recovering from the original file, Vim reads only those | |
1356 parts of a file that are not found in the swap file. Since that is not | |
1357 possible with a BufReadCmd, use the |:preserve| command to make sure the | |
1358 original file isn't needed for recovery. You might want to do this only when | |
1359 you expect the file to be modified. | |
1360 | |
1061 | 1361 For file read and write commands the |v:cmdarg| variable holds the "++enc=" |
1362 and "++ff=" argument that are effective. These should be used for the command | |
1363 that reads/writes the file. The |v:cmdbang| variable is one when "!" was | |
1364 used, zero otherwise. | |

1369 11. Disabling autocommands *autocmd-disable* | |
1370 | |
1371 To disable autocommands for some time use the 'eventignore' option. Note that | |
1372 this may cause unexpected behavior, make sure you restore 'eventignore' | |
1373 afterwards, using a |:try| block with |:finally|. | |
1374 | |
1375 *:noautocmd* *:noa* | |
1376 To disable autocommands for just one command use the ":noautocmd" command | |
1377 modifier. This will set 'eventignore' to "all" for the duration of the | |
1378 following command. Example: > | |
1379 | |
1380 :noautocmd w fname.gz | |
1381 | |
1382 This will write the file without triggering the autocommands defined by the | |
1383 gzip plugin. | |
