25 1. Introduction *autocmd-intro* | |
26 | |
22 | 27 You can specify commands to be executed automatically when reading or writing |
28 a file, when entering or leaving a buffer or window, and when exiting Vim. | |
29 For example, you can create an autocommand to set the 'cindent' option for | |
30 files matching *.c. You can also use autocommands to implement advanced | |
7 | 31 features, such as editing compressed files (see |gzip-example|). The usual |
32 place to put autocommands is in your .vimrc or .exrc file. | |
33 | |
13231 | 34 *E203* *E204* *E143* *E855* *E937* *E952* |
7 | 35 WARNING: Using autocommands is very powerful, and may lead to unexpected side |
36 effects. Be careful not to destroy your text. | |
37 - It's a good idea to do some testing on an expendable copy of a file first. | |
38 For example: If you use autocommands to decompress a file when starting to | |
39 edit it, make sure that the autocommands for compressing when writing work | |
40 correctly. | |
41 - Be prepared for an error halfway through (e.g., disk full). Vim will mostly | |
42 be able to undo the changes to the buffer, but you may have to clean up the | |
43 changes to other files by hand (e.g., compress a file that has been | |
44 decompressed). | |
45 - If the BufRead* events allow you to edit a compressed file, the FileRead* | |
46 events should do the same (this makes recovery possible in some rare cases). | |
47 It's a good idea to use the same autocommands for the File* and Buf* events | |
48 when possible. | |
49 | |
50 ============================================================================== | |
51 2. Defining autocommands *autocmd-define* | |
52 | |
53 *:au* *:autocmd* | |
27162 | 54 :au[tocmd] [group] {event} {aupat} [++once] [++nested] {cmd} |
7 | 55 Add {cmd} to the list of commands that Vim will |
56 execute automatically on {event} for a file matching | |
27162 | 57 {aupat} |autocmd-patterns|. |

40 | 71 The special pattern <buffer> or <buffer=N> defines a buffer-local autocommand. |
72 See |autocmd-buflocal|. | |
73 | |
23164 | 74 If the `:autocmd` is in Vim9 script (a script that starts with `:vim9script` |
75 and in a `:def` function) then {cmd} will be executed as in Vim9 | |
22958 | 76 script. Thus this depends on where the autocmd is defined, not where it is |
77 triggered. | |
78 | |
25619 | 79 {cmd} can be a block, like with `:command`, see |:command-repl|. Example: > |

7 | 98 Note that special characters (e.g., "%", "<cword>") in the ":autocmd" |
99 arguments are not expanded when the autocommand is defined. These will be | |
100 expanded when the Event is recognized, and the {cmd} is executed. The only | |
101 exception is that "<sfile>" is expanded when the autocmd is defined. Example: | |
102 > | |
103 :au BufNewFile,BufRead *.html so <sfile>:h/html.vim | |
104 | |
105 Here Vim expands <sfile> to the name of the file containing this line. | |

116 augroup END |
7 | 117 |
118 If you don't want to remove all autocommands, you can instead use a variable | |
119 to ensure that Vim includes the autocommands only once: > | |
120 | |
121 :if !exists("autocommands_loaded") | |
122 : let autocommands_loaded = 1 | |
123 : au ... | |
124 :endif | |
125 | |
126 When the [group] argument is not given, Vim uses the current group (as defined | |
127 with ":augroup"); otherwise, Vim uses the group defined with [group]. Note | |
128 that [group] must have been defined before. You cannot define a new group | |
129 with ":au group ..."; use ":augroup" for that. | |
130 | |
131 While testing autocommands, you might find the 'verbose' option to be useful: > | |
132 :set verbose=9 | |
133 This setting makes Vim echo the autocommands as it executes them. | |
134 | |
135 When defining an autocommand in a script, it will be able to call functions | |
136 local to the script and use mappings local to the script. When the event is | |
137 triggered and the command executed, it will run in the context of the script | |
138 it was defined in. This matters if |<SID>| is used in a command. | |
139 | |
1621 | 140 When executing the commands, the message from one command overwrites a |
7 | 141 previous message. This is different from when executing the commands |
142 manually. Mostly the screen will not scroll up, thus there is no hit-enter | |
143 prompt. When one command outputs two messages this can happen anyway. | |

7 | 173 |
174 When the [group] argument is not given, Vim uses the current group (as defined | |
175 with ":augroup"); otherwise, Vim uses the group defined with [group]. | |
176 | |
177 ============================================================================== | |
178 4. Listing autocommands *autocmd-list* | |
179 | |
27162 | 180 :au[tocmd] [group] {event} {aupat} |
7 | 181 Show the autocommands associated with {event} and |
27162 | 182 {aupat}. |
7 | 183 |
27162 | 184 :au[tocmd] [group] * {aupat} |
185 Show the autocommands associated with {aupat} for all | |
7 | 186 events. |
187 | |
188 :au[tocmd] [group] {event} | |
189 Show all autocommands for {event}. | |
190 | |
191 :au[tocmd] [group] Show all autocommands. | |
192 | |
193 If you provide the [group] argument, Vim lists only the autocommands for | |
194 [group]; otherwise, Vim lists the autocommands for ALL groups. Note that this | |
195 argument behavior differs from that for defining and removing autocommands. | |
196 | |
40 | 197 In order to list buffer-local autocommands, use a pattern in the form <buffer> |
198 or <buffer=N>. See |autocmd-buflocal|. | |
199 | |
500 | 200 *:autocmd-verbose* |
201 When 'verbose' is non-zero, listing an autocommand will also display where it | |
202 was last defined. Example: > | |
203 | |
204 :verbose autocmd BufEnter | |
205 FileExplorer BufEnter | |
856 | 206 * call s:LocalBrowse(expand("<amatch>")) |
500 | 207 Last set from /usr/share/vim/vim-7.0/plugin/NetrwPlugin.vim |
208 < | |
209 See |:verbose-cmd| for more information. | |
210 | |
7 | 211 ============================================================================== |
212 5. Events *autocmd-events* *E215* *E216* | |
213 | |
579 | 214 You can specify a comma-separated list of event names. No white space can be |
215 used in this list. The command applies to all the events in the list. | |
216 | |
217 For READING FILES there are four kinds of events possible: | |
218 BufNewFile starting to edit a non-existent file | |
219 BufReadPre BufReadPost starting to edit an existing file | |
220 FilterReadPre FilterReadPost read the temp file with filter output | |
221 FileReadPre FileReadPost any other file read | |
222 Vim uses only one of these four kinds when reading a file. The "Pre" and | |
223 "Post" events are both triggered, before and after reading the file. | |
224 | |
225 Note that the autocommands for the *ReadPre events and all the Filter events | |
226 are not allowed to change the current buffer (you will get an error message if | |
227 this happens). This is to prevent the file to be read into the wrong buffer. | |
228 | |
229 Note that the 'modified' flag is reset AFTER executing the BufReadPost | |
230 and BufNewFile autocommands. But when the 'modified' option was set by the | |
231 autocommands, this doesn't happen. | |
232 | |
233 You can use the 'eventignore' option to ignore a number of events or all | |
234 events. | |
7 | 235 *autocommand-events* *{event}* |
236 Vim recognizes the following events. Vim ignores the case of event names | |
237 (e.g., you can use "BUFread" or "bufread" instead of "BufRead"). | |
238 | |
579 | 239 First an overview by function with a short explanation. Then the list |
843 | 240 alphabetically with full explanations |autocmd-events-abc|. |

246 |BufReadPre| starting to edit a new buffer, before reading the file | |

417 during startup. |
579 | 418 The BufCreate event is for historic reasons. |
419 NOTE: When this autocommand is executed, the | |
420 current buffer "%" may be different from the | |
421 buffer being created "<afile>". | |
422 *BufDelete* | |
423 BufDelete Before deleting a buffer from the buffer list. | |
424 The BufUnload may be called first (if the | |
425 buffer was loaded). | |
426 Also used just before a buffer in the buffer | |
427 list is renamed. | |
428 NOTE: When this autocommand is executed, the | |
429 current buffer "%" may be different from the | |
1621 | 430 buffer being deleted "<afile>" and "<abuf>". |
1919 | 431 Don't change to another buffer, it will cause |
432 problems. | |
579 | 433 *BufEnter* |
434 BufEnter After entering a buffer. Useful for setting | |
435 options for a file type. Also executed when | |
436 starting to edit a buffer, after the | |
437 BufReadPost autocommands. | |
438 *BufFilePost* | |
439 BufFilePost After changing the name of the current buffer | |
440 with the ":file" or ":saveas" command. | |
625 | 441 *BufFilePre* |
579 | 442 BufFilePre Before changing the name of the current buffer |
443 with the ":file" or ":saveas" command. | |
444 *BufHidden* | |
17261 | 445 BufHidden Just before a buffer becomes hidden. That is, |
446 when there are no longer windows that show | |
579 | 447 the buffer, but the buffer is not unloaded or |
448 deleted. Not used for ":qa" or ":q" when | |
449 exiting Vim. | |
450 NOTE: When this autocommand is executed, the | |
451 current buffer "%" may be different from the | |
452 buffer being unloaded "<afile>". | |
453 *BufLeave* | |
454 BufLeave Before leaving to another buffer. Also when | |
455 leaving or closing the current window and the | |
456 new current window is not for the same buffer. | |
457 Not used for ":qa" or ":q" when exiting Vim. | |
458 *BufNew* | |
459 BufNew Just after creating a new buffer. Also used | |
460 just after a buffer has been renamed. When | |
461 the buffer is added to the buffer list BufAdd | |
462 will be triggered too. | |
463 NOTE: When this autocommand is executed, the | |
464 current buffer "%" may be different from the | |
465 buffer being created "<afile>". | |
7 | 466 *BufNewFile* |
467 BufNewFile When starting to edit a file that doesn't | |
468 exist. Can be used to read in a skeleton | |
469 file. | |
470 *BufRead* *BufReadPost* | |
471 BufRead or BufReadPost When starting to edit a new buffer, after | |
472 reading the file into the buffer, before | |
473 executing the modelines. See |BufWinEnter| | |
474 for when you need to do something after | |
475 processing the modelines. | |
476 This does NOT work for ":r file". Not used | |
477 when the file doesn't exist. Also used after | |
478 successfully recovering a file. | |
3682 | 479 Also triggered for the filetypedetect group |
480 when executing ":filetype detect" and when | |
481 writing an unnamed buffer in a way that the | |
482 buffer gets a name. | |
625 | 483 *BufReadCmd* |
7 | 484 BufReadCmd Before starting to edit a new buffer. Should |
485 read the file into the buffer. |Cmd-event| | |
625 | 486 *BufReadPre* *E200* *E201* |
579 | 487 BufReadPre When starting to edit a new buffer, before |
488 reading the file into the buffer. Not used | |
489 if the file doesn't exist. | |
490 *BufUnload* | |
491 BufUnload Before unloading a buffer. This is when the | |
492 text in the buffer is going to be freed. This | |
493 may be after a BufWritePost and before a | |
494 BufDelete. Also used for all buffers that are | |
495 loaded when Vim is going to exit. | |
496 NOTE: When this autocommand is executed, the | |
497 current buffer "%" may be different from the | |
498 buffer being unloaded "<afile>". | |

502 event is not triggered. |
579 | 503 *BufWinEnter* |
504 BufWinEnter After a buffer is displayed in a window. This | |
505 can be when the buffer is loaded (after | |
1621 | 506 processing the modelines) or when a hidden |
579 | 507 buffer is displayed in a window (and is no |
1621 | 508 longer hidden). |
509 Does not happen for |:split| without | |
510 arguments, since you keep editing the same | |
511 buffer, or ":split" with a file that's already | |
1668 | 512 open in a window, because it re-uses an |
513 existing buffer. But it does happen for a | |
514 ":split" with the name of the current buffer, | |
515 since it reloads that buffer. | |

528 event is not triggered. |
579 | 529 *BufWipeout* |
530 BufWipeout Before completely deleting a buffer. The | |
531 BufUnload and BufDelete events may be called | |
532 first (if the buffer was loaded and was in the | |
533 buffer list). Also used just before a buffer | |
534 is renamed (also when it's not in the buffer | |
535 list). | |
536 NOTE: When this autocommand is executed, the | |
537 current buffer "%" may be different from the | |
538 buffer being deleted "<afile>". | |
1919 | 539 Don't change to another buffer, it will cause |
540 problems. | |
7 | 541 *BufWrite* *BufWritePre* |
542 BufWrite or BufWritePre Before writing the whole buffer to a file. | |
543 *BufWriteCmd* | |
544 BufWriteCmd Before writing the whole buffer to a file. | |
545 Should do the writing of the file and reset | |
39 | 546 'modified' if successful, unless '+' is in |
547 'cpo' and writing to another file |cpo-+|. | |
548 The buffer contents should not be changed. | |
3082 | 549 When the command resets 'modified' the undo |
550 information is adjusted to mark older undo | |
551 states as 'modified', like |:write| does. | |
39 | 552 |Cmd-event| |
579 | 553 *BufWritePost* |
554 BufWritePost After writing the whole buffer to a file | |
555 (should undo the commands for BufWritePre). | |
6154 | 556 *CmdUndefined* |
557 CmdUndefined When a user command is used but it isn't | |
558 defined. Useful for defining a command only | |
559 when it's used. The pattern is matched | |
560 against the command name. Both <amatch> and | |
561 <afile> are set to the name of the command. | |
562 NOTE: Autocompletion won't work until the | |
563 command is defined. An alternative is to | |
564 always define the user command and have it | |
565 invoke an autoloaded function. See |autoload|. | |

661 fire every 'updatetime' ms if you leave Vim to | |
662 make some coffee. :) See |CursorHold-example| | |
663 for previewing tags. | |
664 This event is only triggered in Normal mode. | |
1154 | 665 It is not triggered when waiting for a command |
666 argument to be typed, or a movement after an | |
667 operator. | |

669 triggered. |q| | |

671 Internally the autocommand is triggered by the | |
672 <CursorHold> key. In an expression mapping | |
673 |getchar()| may see this character. | |
674 | |
579 | 675 Note: Interactive commands cannot be used for |
676 this event. There is no hit-enter prompt, | |
677 the screen is updated directly (when needed). | |
678 Note: In the future there will probably be | |
679 another option to set the time. | |
680 Hint: to force an update of the status lines | |
681 use: > | |

699 cursor position. | |
667 | 700 For an example see |match-parens|. |
16023 | 701 Note: This can not be skipped with |
702 `:noautocmd`. | |
4264 | 703 Careful: This is triggered very often, don't |
704 do anything that the user does not expect or | |
705 that is slow. | |

724 file. Can be used to check-out the file from | |
725 a source control system. Not triggered when | |
726 the change was caused by an autocommand. | |
727 This event is triggered when making the first | |
728 change in a buffer or the first change after | |
823 | 729 'readonly' was set, just before the change is |
730 applied to the text. | |
579 | 731 WARNING: If the autocommand moves the cursor |

766 cancelled if there is a modified buffer that | |
767 isn't automatically saved, use |VimLeavePre| | |
768 for really exiting. | |
7 | 769 *FileChangedShell* |
770 FileChangedShell When Vim notices that the modification time of | |
771 a file has changed since editing started. | |
772 Also when the file attributes of the file | |
5908 | 773 change or when the size of the file changes. |
774 |timestamp| | |
7 | 775 Mostly triggered after executing a shell |
776 command, but also with a |:checktime| command | |
11473 | 777 or when gvim regains input focus. |
7 | 778 This autocommand is triggered for each changed |
779 file. It is not used when 'autoread' is set | |
780 and the buffer was not changed. If a | |
781 FileChangedShell autocommand is present the | |
782 warning message and prompt is not given. | |
179 | 783 The |v:fcs_reason| variable is set to indicate |
784 what happened and |v:fcs_choice| can be used | |
785 to tell Vim what to do next. | |
7 | 786 NOTE: When this autocommand is executed, the |
787 current buffer "%" may be different from the | |
11347 | 788 buffer that was changed, which is in "<afile>". |
7 | 789 NOTE: The commands must not change the current |
790 buffer, jump to another buffer or delete a | |

791 buffer. *E246* *E811* |
7 | 792 NOTE: This event never nests, to avoid an |
793 endless loop. This means that while executing | |
794 commands for the FileChangedShell event no | |
795 other FileChangedShell event will be | |
796 triggered. | |
766 | 797 *FileChangedShellPost* |
798 FileChangedShellPost After handling a file that was changed outside | |
799 of Vim. Can be used to update the statusline. | |
579 | 800 *FileEncoding* |
801 FileEncoding Obsolete. It still works and is equivalent | |
802 to |EncodingChanged|. | |
803 *FileReadCmd* | |
804 FileReadCmd Before reading a file with a ":read" command. | |
805 Should do the reading of the file. |Cmd-event| | |
806 *FileReadPost* | |
807 FileReadPost After reading a file with a ":read" command. | |
808 Note that Vim sets the '[ and '] marks to the | |
809 first and last line of the read. This can be | |
810 used to operate on the lines just read. | |
811 *FileReadPre* | |
812 FileReadPre Before reading a file with a ":read" command. | |
813 *FileType* | |
1154 | 814 FileType When the 'filetype' option has been set. The |
815 pattern is matched against the filetype. | |
579 | 816 <afile> can be used for the name of the file |

821 *FileWriteCmd* | |
822 FileWriteCmd Before writing to a file, when not writing the | |
823 whole buffer. Should do the writing to the | |
824 file. Should not change the buffer. Use the | |
825 '[ and '] marks for the range of lines. | |
826 |Cmd-event| | |
827 *FileWritePost* | |
828 FileWritePost After writing to a file, when not writing the | |

830 *FileWritePre* | |
831 FileWritePre Before writing to a file, when not writing the | |
832 whole buffer. Use the '[ and '] marks for the | |
833 range of lines. | |
834 *FilterReadPost* | |
835 FilterReadPost After reading a file from a filter command. | |
836 Vim checks the pattern against the name of | |
837 the current buffer as with FilterReadPre. | |
838 Not triggered when 'shelltemp' is off. | |
839 *FilterReadPre* *E135* | |
840 FilterReadPre Before reading a file from a filter command. | |
841 Vim checks the pattern against the name of | |
842 the current buffer, not the name of the | |
843 temporary file that is the output of the | |
844 filter command. | |
845 Not triggered when 'shelltemp' is off. | |
846 *FilterWritePost* | |
847 FilterWritePost After writing a file for a filter command or | |
15334 | 848 making a diff with an external diff (see |

859 filter command. | |
860 Not triggered when 'shelltemp' is off. | |
7 | 861 *FocusGained* |
862 FocusGained When Vim got input focus. Only for the GUI | |
863 version and a few console versions where this | |
864 can be detected. | |
865 *FocusLost* | |
866 FocusLost When Vim lost input focus. Only for the GUI | |
867 version and a few console versions where this | |
11 | 868 can be detected. May also happen when a |
869 dialog pops up. | |
7 | 870 *FuncUndefined* |
871 FuncUndefined When a user function is used but it isn't | |
872 defined. Useful for defining a function only | |
1154 | 873 when it's used. The pattern is matched |
874 against the function name. Both <amatch> and | |
875 <afile> are set to the name of the function. | |
23305 | 876 Not triggered when compiling a |Vim9| |
877 function. | |
6154 | 878 NOTE: When writing Vim scripts a better |
879 alternative is to use an autoloaded function. | |
161 | 880 See |autoload-functions|. |
579 | 881 *GUIEnter* |
882 GUIEnter After starting the GUI successfully, and after | |
883 opening the window. It is triggered before | |
884 VimEnter when using gvim. Can be used to | |
885 position the window from a .gvimrc file: > | |
886 :autocmd GUIEnter * winpos 100 50 | |
1154 | 887 < *GUIFailed* |
888 GUIFailed After starting the GUI failed. Vim may | |
889 continue to run in the terminal, if possible | |
890 (only on Unix and alikes, when connecting the | |
891 X server fails). You may want to quit Vim: > | |
892 :autocmd GUIFailed * qall | |
579 | 893 < *InsertChange* |
894 InsertChange When typing <Insert> while in Insert or | |
895 Replace mode. The |v:insertmode| variable | |
896 indicates the new mode. | |
897 Be careful not to move the cursor or do | |
898 anything else that the user does not expect. | |
2845 | 899 *InsertCharPre* |
900 InsertCharPre When a character is typed in Insert mode, | |
901 before inserting the char. | |
902 The |v:char| variable indicates the char typed | |
903 and can be changed during the event to insert | |
904 a different character. When |v:char| is set | |
905 to more than one character this text is | |
906 inserted literally. | |
907 It is not allowed to change the text |textlock|. | |
908 The event is not triggered when 'paste' is | |
13437 | 909 set. {only with the +eval feature} |
579 | 910 *InsertEnter* |
1154 | 911 InsertEnter Just before starting Insert mode. Also for |
912 Replace mode and Virtual Replace mode. The | |
579 | 913 |v:insertmode| variable indicates the mode. |
4448 | 914 Be careful not to do anything else that the |
915 user does not expect. | |
916 The cursor is restored afterwards. If you do | |
917 not want that set |v:char| to a non-empty | |
918 string. | |

1344 The {aupat} argument of `:autocmd` can be a comma-separated list. This works as |
27162 | 1345 if the command was given with each pattern separately. Thus this command: > |
6741 | 1346 :autocmd BufRead *.txt,*.info set et |
1347 Is equivalent to: > | |
1348 :autocmd BufRead *.txt set et | |
1349 :autocmd BufRead *.info set et | |
1350 | |
27162 | 1351 The file pattern {aupat} is tested for a match against the file name in one of |
7 | 1352 two ways: |
1353 1. When there is no '/' in the pattern, Vim checks for a match against only | |
1354 the tail part of the file name (without its leading directory path). | |

1357 it to a full path and resolving symbolic links). |
7 | 1358 |
40 | 1359 The special pattern <buffer> or <buffer=N> is used for buffer-local |
1360 autocommands |autocmd-buflocal|. This pattern is not matched against the name | |
1361 of a buffer. | |
1362 | |
7 | 1363 Examples: > |
1364 :autocmd BufRead *.txt set et | |
1365 Set the 'et' option for all text files. > | |
1366 | |
1367 :autocmd BufRead /vim/src/*.c set cindent | |
1368 Set the 'cindent' option for C files in the /vim/src directory. > | |
1369 | |
1370 :autocmd BufRead /tmp/*.c set ts=5 | |
1371 If you have a link from "/tmp/test.c" to "/home/nobody/vim/src/test.c", and | |
1372 you start editing "/tmp/test.c", this autocommand will match. | |
1373 | |
1374 Note: To match part of a path, but not from the root directory, use a '*' as | |
1375 the first character. Example: > | |
1376 :autocmd BufRead */doc/*.txt set tw=78 | |
1377 This autocommand will for example be executed for "/tmp/doc/xx.txt" and | |
1378 "/usr/home/piet/doc/yy.txt". The number of directories does not matter here. | |
1379 | |
1380 | |
1381 The file name that the pattern is matched against is after expanding | |
1621 | 1382 wildcards. Thus if you issue this command: > |
7 | 1383 :e $ROOTDIR/main.$EXT |
1384 The argument is first expanded to: > | |
1385 /usr/root/main.py | |
1386 Before it's matched with the pattern of the autocommand. Careful with this | |
1387 when using events like FileReadCmd, the value of <amatch> may not be what you | |
1388 expect. | |
1389 | |
1390 | |
1391 Environment variables can be used in a pattern: > | |
1392 :autocmd BufRead $VIMRUNTIME/doc/*.txt set expandtab | |
1393 And ~ can be used for the home directory (if $HOME is defined): > | |
1394 :autocmd BufWritePost ~/.vimrc so ~/.vimrc | |
1395 :autocmd BufRead ~archive/* set readonly | |
1396 The environment variable is expanded when the autocommand is defined, not when | |
1397 the autocommand is executed. This is different from the command! | |
1398 | |
1399 *file-pattern* | |
1400 The pattern is interpreted like mostly used in file names: | |
5294 | 1401 * matches any sequence of characters; Unusual: includes path |
5277 | 1402 separators |
7 | 1403 ? matches any single character |
1404 \? matches a '?' | |
1405 . matches a '.' | |
1406 ~ matches a '~' | |
1407 , separates patterns | |
1408 \, matches a ',' | |
1409 { } like \( \) in a |pattern| | |
1410 , inside { }: like \| in a |pattern| | |

40 | 1425 *autocmd-changes* |
7 | 1426 Matching with the pattern is done when an event is triggered. Changing the |
1427 buffer name in one of the autocommands, or even deleting the buffer, does not | |
1428 change which autocommands will be executed. Example: > | |
1429 | |
1430 au BufEnter *.foo bdel | |
1431 au BufEnter *.foo set modified | |
1432 | |
1433 This will delete the current buffer and then set 'modified' in what has become | |
1434 the current buffer instead. Vim doesn't take into account that "*.foo" | |
1435 doesn't match with that buffer name. It matches "*.foo" with the name of the | |
1436 buffer at the moment the event was triggered. | |
1437 | |
40 | 1438 However, buffer-local autocommands will not be executed for a buffer that has |
1439 been wiped out with |:bwipe|. After deleting the buffer with |:bdel| the | |
1440 buffer actually still exists (it becomes unlisted), thus the autocommands are | |
1441 still executed. | |
1442 | |
7 | 1443 ============================================================================== |
856 | 1444 7. Buffer-local autocommands *autocmd-buflocal* *autocmd-buffer-local* |
1445 *<buffer=N>* *<buffer=abuf>* *E680* | |
40 | 1446 |
1447 Buffer-local autocommands are attached to a specific buffer. They are useful | |
1448 if the buffer does not have a name and when the name does not match a specific | |
1449 pattern. But it also means they must be explicitly added to each buffer. | |
1450 | |
1451 Instead of a pattern buffer-local autocommands use one of these forms: | |
1452 <buffer> current buffer | |
1453 <buffer=99> buffer number 99 | |
1454 <buffer=abuf> using <abuf> (only when executing autocommands) | |
1455 |<abuf>| | |
1456 | |
1457 Examples: > | |
1458 :au CursorHold <buffer> echo 'hold' | |
1459 :au CursorHold <buffer=33> echo 'hold' | |

|
1460 :au BufNewFile * au CursorHold <buffer=abuf> echo 'hold' |
40 | 1461 |
1462 All the commands for autocommands also work with buffer-local autocommands, | |
1463 simply use the special string instead of the pattern. Examples: > | |
856 | 1464 :au! * <buffer> " remove buffer-local autocommands for |
1465 " current buffer | |
1466 :au! * <buffer=33> " remove buffer-local autocommands for | |
1467 " buffer #33 | |
1621 | 1468 :bufdo :au! CursorHold <buffer> " remove autocmd for given event for all |
856 | 1469 " buffers |
1470 :au * <buffer> " list buffer-local autocommands for | |
1471 " current buffer | |
40 | 1472 |
1473 Note that when an autocommand is defined for the current buffer, it is stored | |
1474 with the buffer number. Thus it uses the form "<buffer=12>", where 12 is the | |
1475 number of the current buffer. You will see this when listing autocommands, | |
1476 for example. | |
1477 | |
1478 To test for presence of buffer-local autocommands use the |exists()| function | |
1479 as follows: > | |
1480 :if exists("#CursorHold#<buffer=12>") | ... | endif | |
1481 :if exists("#CursorHold#<buffer>") | ... | endif " for current buffer | |
1482 | |
1483 When a buffer is wiped out its buffer-local autocommands are also gone, of | |
1484 course. Note that when deleting a buffer, e.g., with ":bdel", it is only | |
1485 unlisted, the autocommands are still present. In order to see the removal of | |
1486 buffer-local autocommands: > | |
1487 :set verbose=6 | |
1488 | |
1489 It is not possible to define buffer-local autocommands for a non-existent | |
1490 buffer. | |
1491 | |
1492 ============================================================================== | |
1493 8. Groups *autocmd-groups* | |
7 | 1494 |
1495 Autocommands can be put together in a group. This is useful for removing or | |
1496 executing a group of autocommands. For example, all the autocommands for | |
1497 syntax highlighting are put in the "highlight" group, to be able to execute | |
1498 ":doautoall highlight BufRead" when the GUI starts. | |
1499 | |
1500 When no specific group is selected, Vim uses the default group. The default | |
1501 group does not have a name. You cannot execute the autocommands from the | |
1502 default group separately; you can execute them only by executing autocommands | |
1503 for all groups. | |
1504 | |
1505 Normally, when executing autocommands automatically, Vim uses the autocommands | |
1506 for all groups. The group only matters when executing autocommands with | |
1507 ":doautocmd" or ":doautoall", or when defining or deleting autocommands. | |
1508 | |
1509 The group name can contain any characters except white space. The group name | |
1510 "end" is reserved (also in uppercase). | |
1511 | |
1512 The group name is case sensitive. Note that this is different from the event | |
1513 name! | |
1514 | |
1515 *:aug* *:augroup* | |
1516 :aug[roup] {name} Define the autocmd group name for the | |
1517 following ":autocmd" commands. The name "end" | |
1518 or "END" selects the default group. | |

1526 this group! You will get a warning if doing |
21676 | 1527 it anyway. When the group is the current |
1528 group you will get error E936. | |
7 | 1529 |
1530 To enter autocommands for a specific group, use this method: | |
1531 1. Select the group with ":augroup {name}". | |
1532 2. Delete any old autocommands with ":au!". | |
1533 3. Define the autocommands. | |
1534 4. Go back to the default group with "augroup END". | |
1535 | |
1536 Example: > | |
1537 :augroup uncompress | |
1538 : au! | |
1539 : au BufEnter *.gz %!gunzip | |
1540 :augroup END | |
1541 | |
1542 This prevents having the autocommands defined twice (e.g., after sourcing the | |
1543 .vimrc file again). | |
1544 | |
25880 | 1545 *FileExplorer* |
1546 There is one group that is recognized by Vim: FileExplorer. If this group | |
1547 exists Vim assumes that editing a directory is possible and will trigger a | |
1548 plugin that lists the files in that directory. This is used by the |netrw| | |
1549 plugin. This allows you to do: > | |
1550 browse edit | |
1551 | |
7 | 1552 ============================================================================== |
40 | 1553 9. Executing autocommands *autocmd-execute* |
7 | 1554 |
1555 Vim can also execute Autocommands non-automatically. This is useful if you | |
1556 have changed autocommands, or when Vim has executed the wrong autocommands | |
1557 (e.g., the file pattern match was wrong). | |
1558 | |
1559 Note that the 'eventignore' option applies here too. Events listed in this | |
1560 option will not cause any commands to be executed. | |
1561 | |
16944 | 1562 *:do* *:doau* *:doaut* *:doautocmd* *E217* |
3356 | 1563 :do[autocmd] [<nomodeline>] [group] {event} [fname] |
7 | 1564 Apply the autocommands matching [fname] (default: |
1565 current file name) for {event} to the current buffer. | |
1566 You can use this when the current file name does not | |
1567 match the right pattern, after changing settings, or | |
1568 to execute autocommands for a certain event. | |
1569 It's possible to use this inside an autocommand too, | |
1570 so you can base the autocommands for one extension on | |
1571 another extension. Example: > | |
3224 | 1572 :au BufEnter *.cpp so ~/.vimrc_cpp |
1573 :au BufEnter *.cpp doau BufEnter x.c | |
7 | 1574 < Be careful to avoid endless loops. See |
1575 |autocmd-nested|. | |
1576 | |
1577 When the [group] argument is not given, Vim executes | |
1578 the autocommands for all groups. When the [group] | |
1579 argument is included, Vim executes only the matching | |
1580 autocommands for that group. Note: if you use an | |
1581 undefined group name, Vim gives you an error message. | |
3350 | 1582 *<nomodeline>* |
1583 After applying the autocommands the modelines are | |
1584 processed, so that their settings overrule the | |
1585 settings from autocommands, like what happens when | |
1586 editing a file. This is skipped when the <nomodeline> | |
1587 argument is present. You probably want to use | |
1588 <nomodeline> for events that are not used when loading | |
1589 a buffer, such as |User|. | |

1591 matching autocommands were executed. |
7 | 1592 |
1593 *:doautoa* *:doautoall* | |
3342 | 1594 :doautoa[ll] [<nomodeline>] [group] {event} [fname] |
7 | 1595 Like ":doautocmd", but apply the autocommands to each |
24278 | 1596 loaded buffer. The current buffer is done last. |
1597 | |
1598 Note that [fname] is used to select the autocommands, | |
24569 | 1599 not the buffers to which they are applied. Example: > |
1600 augroup mine | |
1601 autocmd! | |
1602 autocmd FileType * echo expand('<amatch>') | |
1603 augroup END | |
1604 doautoall mine FileType Loaded-Buffer | |
1605 < Sourcing this script, you'll see as many | |
1606 "Loaded-Buffer" echoed as there are loaded buffers. | |
24278 | 1607 |
7 | 1608 Careful: Don't use this for autocommands that delete a |
1609 buffer, change to another buffer or change the | |
1610 contents of a buffer; the result is unpredictable. | |
1611 This command is intended for autocommands that set | |
1612 options, change highlighting, and things like that. | |
1613 | |
1614 ============================================================================== | |
40 | 1615 10. Using autocommands *autocmd-use* |
7 | 1616 |
1617 For WRITING FILES there are four possible sets of events. Vim uses only one | |
1618 of these sets for a write command: | |
1619 | |
1620 BufWriteCmd BufWritePre BufWritePost writing the whole buffer | |
1621 FilterWritePre FilterWritePost writing to filter temp file | |
1622 FileAppendCmd FileAppendPre FileAppendPost appending to a file | |
1623 FileWriteCmd FileWritePre FileWritePost any other file write | |
1624 | |
1625 When there is a matching "*Cmd" autocommand, it is assumed it will do the | |
1626 writing. No further writing is done and the other events are not triggered. | |
1627 |Cmd-event| | |
1628 | |
1629 Note that the *WritePost commands should undo any changes to the buffer that | |
1630 were caused by the *WritePre commands; otherwise, writing the file will have | |
1631 the side effect of changing the buffer. | |
1632 | |
1633 Before executing the autocommands, the buffer from which the lines are to be | |
1634 written temporarily becomes the current buffer. Unless the autocommands | |
1635 change the current buffer or delete the previously current buffer, the | |
1636 previously current buffer is made the current buffer again. | |
1637 | |
1638 The *WritePre and *AppendPre autocommands must not delete the buffer from | |
1639 which the lines are to be written. | |
1640 | |
1641 The '[ and '] marks have a special position: | |
1642 - Before the *ReadPre event the '[ mark is set to the line just above where | |
1643 the new lines will be inserted. | |
1644 - Before the *ReadPost event the '[ mark is set to the first line that was | |
1645 just read, the '] mark to the last line. | |
26 | 1646 - Before executing the *WriteCmd, *WritePre and *AppendPre autocommands the '[ |
1647 mark is set to the first line that will be written, the '] mark to the last | |
1648 line. | |
7 | 1649 Careful: '[ and '] change when using commands that change the buffer. |
1650 | |
1651 In commands which expect a file name, you can use "<afile>" for the file name | |
1652 that is being read |:<afile>| (you can also use "%" for the current file | |
1653 name). "<abuf>" can be used for the buffer number of the currently effective | |
14123 | 1654 buffer. This also works for buffers that don't have a name. But it doesn't |
7 | 1655 work for files without a buffer (e.g., with ":r file"). |
1656 | |
1657 *gzip-example* | |
1658 Examples for reading and writing compressed files: > | |
1659 :augroup gzip | |
1660 : autocmd! | |
1661 : autocmd BufReadPre,FileReadPre *.gz set bin | |
1662 : autocmd BufReadPost,FileReadPost *.gz '[,']!gunzip | |
1663 : autocmd BufReadPost,FileReadPost *.gz set nobin | |
27903 | 1664 : autocmd BufReadPost,FileReadPost *.gz execute ":doautocmd BufReadPost " .. expand("%:r") |
7 | 1665 : autocmd BufWritePost,FileWritePost *.gz !mv <afile> <afile>:r |
1666 : autocmd BufWritePost,FileWritePost *.gz !gzip <afile>:r | |
1667 | |
1668 : autocmd FileAppendPre *.gz !gunzip <afile> | |
1669 : autocmd FileAppendPre *.gz !mv <afile>:r <afile> | |
1670 : autocmd FileAppendPost *.gz !mv <afile> <afile>:r | |
1671 : autocmd FileAppendPost *.gz !gzip <afile>:r | |
1672 :augroup END | |
1673 | |
1674 The "gzip" group is used to be able to delete any existing autocommands with | |
1675 ":autocmd!", for when the file is sourced twice. | |
1676 | |
1677 ("<afile>:r" is the file name without the extension, see |:_%:|) | |
1678 | |
1679 The commands executed for the BufNewFile, BufRead/BufReadPost, BufWritePost, | |
1680 FileAppendPost and VimLeave events do not set or reset the changed flag of the | |
1681 buffer. When you decompress the buffer with the BufReadPost autocommands, you | |
1682 can still exit with ":q". When you use ":undo" in BufWritePost to undo the | |
1683 changes made by BufWritePre commands, you can still do ":q" (this also makes | |
1684 "ZZ" work). If you do want the buffer to be marked as modified, set the | |
1685 'modified' option. | |
1686 | |
1687 To execute Normal mode commands from an autocommand, use the ":normal" | |
1688 command. Use with care! If the Normal mode command is not finished, the user | |
1689 needs to type characters (e.g., after ":normal m" you need to type a mark | |
1690 name). | |
1691 | |
1692 If you want the buffer to be unmodified after changing it, reset the | |
1693 'modified' option. This makes it possible to exit the buffer with ":q" | |
1694 instead of ":q!". | |
1695 | |
1696 *autocmd-nested* *E218* | |
16023 | 1697 By default, autocommands do not nest. For example, if you use ":e" or ":w" in |
1698 an autocommand, Vim does not execute the BufRead and BufWrite autocommands for | |
7 | 1699 those commands. If you do want this, use the "nested" flag for those commands |
1700 in which you want nesting. For example: > | |

|
1701 :autocmd FileChangedShell *.c ++nested e! |
7 | 1702 The nesting is limited to 10 levels to get out of recursive loops. |
1703 | |
1704 It's possible to use the ":au" command in an autocommand. This can be a | |
1705 self-modifying command! This can be useful for an autocommand that should | |
1706 execute only once. | |
1707 | |
590 | 1708 If you want to skip autocommands for one command, use the |:noautocmd| command |
1709 modifier or the 'eventignore' option. | |
7 | 1710 |
1711 Note: When reading a file (with ":read file" or with a filter command) and the | |
1712 last line in the file does not have an <EOL>, Vim remembers this. At the next | |
1713 write (with ":write file" or with a filter command), if the same line is | |
1714 written again as the last line in a file AND 'binary' is set, Vim does not | |
1715 supply an <EOL>. This makes a filter command on the just read lines write the | |
1716 same file as was read, and makes a write command on just filtered lines write | |
1717 the same file as was read from the filter. For example, another way to write | |
1718 a compressed file: > | |
1719 | |
1720 :autocmd FileWritePre *.gz set bin|'[,']!gzip | |
1721 :autocmd FileWritePost *.gz undo|set nobin | |
1722 < | |
1723 *autocommand-pattern* | |
1724 You can specify multiple patterns, separated by commas. Here are some | |
1725 examples: > | |
1726 | |
1727 :autocmd BufRead * set tw=79 nocin ic infercase fo=2croq | |
1728 :autocmd BufRead .letter set tw=72 fo=2tcrq | |
1729 :autocmd BufEnter .letter set dict=/usr/lib/dict/words | |
1730 :autocmd BufLeave .letter set dict= | |
1731 :autocmd BufRead,BufNewFile *.c,*.h set tw=0 cin noic | |
1732 :autocmd BufEnter *.c,*.h abbr FOR for (i = 0; i < 3; ++i)<CR>{<CR>}<Esc>O | |
1733 :autocmd BufLeave *.c,*.h unabbr FOR | |
1734 | |
1735 For makefiles (makefile, Makefile, imakefile, makefile.unix, etc.): > | |
1736 | |
1737 :autocmd BufEnter ?akefile* set include=^s\=include | |
1738 :autocmd BufLeave ?akefile* set include& | |
1739 | |
1740 To always start editing C files at the first function: > | |
1741 | |
1742 :autocmd BufRead *.c,*.h 1;/^{ | |
1743 | |
1744 Without the "1;" above, the search would start from wherever the file was | |
1745 entered, rather than from the start of the file. | |
1746 | |
1747 *skeleton* *template* | |
1748 To read a skeleton (template) file when opening a new file: > | |
1749 | |
1750 :autocmd BufNewFile *.c 0r ~/vim/skeleton.c | |
1751 :autocmd BufNewFile *.h 0r ~/vim/skeleton.h | |
1752 :autocmd BufNewFile *.java 0r ~/vim/skeleton.java | |
1753 | |
1754 To insert the current date and time in a *.html file when writing it: > | |
1755 | |
1756 :autocmd BufWritePre,FileWritePre *.html ks|call LastMod()|'s | |
1757 :fun LastMod() | |
1758 : if line("$") > 20 | |
1759 : let l = 20 | |
1760 : else | |
1761 : let l = line("$") | |
1762 : endif | |
27903 | 1763 : exe "1," .. l .. "g/Last modified: /s/Last modified: .*/Last modified: " .. |
7 | 1764 : \ strftime("%Y %b %d") |
1765 :endfun | |
1766 | |
1767 You need to have a line "Last modified: <date time>" in the first 20 lines | |
1768 of the file for this to work. Vim replaces <date time> (and anything in the | |
1769 same line after it) with the current date and time. Explanation: | |
1770 ks mark current position with mark 's' | |
1771 call LastMod() call the LastMod() function to do the work | |
1772 's return the cursor to the old position | |
1773 The LastMod() function checks if the file is shorter than 20 lines, and then | |
1774 uses the ":g" command to find lines that contain "Last modified: ". For those | |
1775 lines the ":s" command is executed to replace the existing date with the | |
1776 current one. The ":execute" command is used to be able to use an expression | |
1777 for the ":g" and ":s" commands. The date is obtained with the strftime() | |
1778 function. You can change its argument to get another date string. | |
1779 | |
1780 When entering :autocmd on the command-line, completion of events and command | |
1781 names may be done (with <Tab>, CTRL-D, etc.) where appropriate. | |
1782 | |
1783 Vim executes all matching autocommands in the order that you specify them. | |
1784 It is recommended that your first autocommand be used for all files by using | |
1785 "*" as the file pattern. This means that you can define defaults you like | |
1786 here for any settings, and if there is another matching autocommand it will | |
1787 override these. But if there is no other matching autocommand, then at least | |
1788 your default settings are recovered (if entering this file from another for | |
1789 which autocommands did match). Note that "*" will also match files starting | |
1790 with ".", unlike Unix shells. | |
1791 | |
1792 *autocmd-searchpat* | |
1793 Autocommands do not change the current search patterns. Vim saves the current | |
1794 search patterns before executing autocommands then restores them after the | |
1795 autocommands finish. This means that autocommands do not affect the strings | |
1796 highlighted with the 'hlsearch' option. Within autocommands, you can still | |
1797 use search patterns normally, e.g., with the "n" command. | |
1798 If you want an autocommand to set the search pattern, such that it is used | |
1799 after the autocommand finishes, use the ":let @/ =" command. | |
1800 The search-highlighting cannot be switched off with ":nohlsearch" in an | |
1801 autocommand. Use the 'h' flag in the 'viminfo' option to disable search- | |
1802 highlighting when starting Vim. | |
1803 | |
1804 *Cmd-event* | |
1805 When using one of the "*Cmd" events, the matching autocommands are expected to | |
1061 | 1806 do the file reading, writing or sourcing. This can be used when working with |
1807 a special kind of file, for example on a remote system. | |
7 | 1808 CAREFUL: If you use these events in a wrong way, it may have the effect of |
1809 making it impossible to read or write the matching files! Make sure you test | |
1810 your autocommands properly. Best is to use a pattern that will never match a | |
1811 normal file name, for example "ftp://*". | |
1812 | |
1813 When defining a BufReadCmd it will be difficult for Vim to recover a crashed | |
1814 editing session. When recovering from the original file, Vim reads only those | |
1815 parts of a file that are not found in the swap file. Since that is not | |
1816 possible with a BufReadCmd, use the |:preserve| command to make sure the | |
1817 original file isn't needed for recovery. You might want to do this only when | |
1818 you expect the file to be modified. | |
1819 | |
1061 | 1820 For file read and write commands the |v:cmdarg| variable holds the "++enc=" |
1821 and "++ff=" argument that are effective. These should be used for the command | |
1822 that reads/writes the file. The |v:cmdbang| variable is one when "!" was | |
1823 used, zero otherwise. | |

1828 11. Disabling autocommands *autocmd-disable* | |
1829 | |
1830 To disable autocommands for some time use the 'eventignore' option. Note that | |
1831 this may cause unexpected behavior, make sure you restore 'eventignore' | |
1832 afterwards, using a |:try| block with |:finally|. | |
1833 | |
1834 *:noautocmd* *:noa* | |
1835 To disable autocommands for just one command use the ":noautocmd" command | |
1836 modifier. This will set 'eventignore' to "all" for the duration of the | |
1837 following command. Example: > | |
1838 | |
1839 :noautocmd w fname.gz | |
1840 | |
1841 This will write the file without triggering the autocommands defined by the | |
1842 gzip plugin. | |
1843 | |
16023 | 1844 Note that some autocommands are not triggered right away, but only later. |
1845 This specifically applies to |CursorMoved| and |TextChanged|. | |
