| 24 ============================================================================== | |
| 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. | |

| 40 | 93 The special pattern <buffer> or <buffer=N> defines a buffer-local autocommand. |
| 94 See |autocmd-buflocal|. | |
| 95 | |
| 23164 | 96 If the `:autocmd` is in Vim9 script (a script that starts with `:vim9script` |
| 97 and in a `:def` function) then {cmd} will be executed as in Vim9 | |
| 22958 | 98 script. Thus this depends on where the autocmd is defined, not where it is |

| 129 > | |

| 131 | |

| 145 If you don't want to remove all autocommands, you can instead use a variable | |
| 146 to ensure that Vim includes the autocommands only once: > | |
| 147 | |
| 148 :if !exists("autocommands_loaded") | |
| 149 : let autocommands_loaded = 1 | |
| 150 : au ... | |
| 151 :endif | |
| 152 | |
| 153 When the [group] argument is not given, Vim uses the current group (as defined | |
| 154 with ":augroup"); otherwise, Vim uses the group defined with [group]. Note | |
| 155 that [group] must have been defined before. You cannot define a new group | |
| 156 with ":au group ..."; use ":augroup" for that. | |
| 157 | |
| 158 While testing autocommands, you might find the 'verbose' option to be useful: > | |
| 159 :set verbose=9 | |
| 160 This setting makes Vim echo the autocommands as it executes them. | |
| 161 | |
| 162 When defining an autocommand in a script, it will be able to call functions | |
| 163 local to the script and use mappings local to the script. When the event is | |
| 164 triggered and the command executed, it will run in the context of the script | |
| 165 it was defined in. This matters if |<SID>| is used in a command. | |
| 166 | |
| 1621 | 167 When executing the commands, the message from one command overwrites a |
| 7 | 168 previous message. This is different from when executing the commands |
| 169 manually. Mostly the screen will not scroll up, thus there is no hit-enter | |
| 170 prompt. When one command outputs two messages this can happen anyway. | |

202 group, it breaks plugins, syntax highlighting, etc. |
| 7 | 203 |
| 204 When the [group] argument is not given, Vim uses the current group (as defined | |
| 205 with ":augroup"); otherwise, Vim uses the group defined with [group]. | |
| 206 | |
| 207 ============================================================================== | |
| 208 4. Listing autocommands *autocmd-list* | |
| 209 | |
| 27162 | 210 :au[tocmd] [group] {event} {aupat} |
| 7 | 211 Show the autocommands associated with {event} and |
| 27162 | 212 {aupat}. |
| 7 | 213 |
| 27162 | 214 :au[tocmd] [group] * {aupat} |
| 215 Show the autocommands associated with {aupat} for all | |
| 7 | 216 events. |
| 217 | |
| 218 :au[tocmd] [group] {event} | |
| 219 Show all autocommands for {event}. | |
| 220 | |
| 221 :au[tocmd] [group] Show all autocommands. | |
| 222 | |
| 223 If you provide the [group] argument, Vim lists only the autocommands for | |
| 224 [group]; otherwise, Vim lists the autocommands for ALL groups. Note that this | |
| 225 argument behavior differs from that for defining and removing autocommands. | |
| 226 | |
| 40 | 227 In order to list buffer-local autocommands, use a pattern in the form <buffer> |
| 228 or <buffer=N>. See |autocmd-buflocal|. | |

| 500 | 233 *:autocmd-verbose* |
| 234 When 'verbose' is non-zero, listing an autocommand will also display where it | |
| 235 was last defined. Example: > | |
| 236 | |
| 237 :verbose autocmd BufEnter | |
| 238 FileExplorer BufEnter | |
| 856 | 239 * call s:LocalBrowse(expand("<amatch>")) |
| 500 | 240 Last set from /usr/share/vim/vim-7.0/plugin/NetrwPlugin.vim |
| 241 < | |
| 242 See |:verbose-cmd| for more information. | |
| 243 | |
| 7 | 244 ============================================================================== |
| 245 5. Events *autocmd-events* *E215* *E216* | |
| 246 | |
| 579 | 247 You can specify a comma-separated list of event names. No white space can be |
| 248 used in this list. The command applies to all the events in the list. | |
| 249 | |
| 250 For READING FILES there are four kinds of events possible: | |
| 251 BufNewFile starting to edit a non-existent file | |
| 252 BufReadPre BufReadPost starting to edit an existing file | |
| 253 FilterReadPre FilterReadPost read the temp file with filter output | |
| 254 FileReadPre FileReadPost any other file read | |
| 255 Vim uses only one of these four kinds when reading a file. The "Pre" and | |
| 256 "Post" events are both triggered, before and after reading the file. | |
| 257 | |
| 258 Note that the autocommands for the *ReadPre events and all the Filter events | |
| 259 are not allowed to change the current buffer (you will get an error message if | |
| 260 this happens). This is to prevent the file to be read into the wrong buffer. | |
| 261 | |
| 262 Note that the 'modified' flag is reset AFTER executing the BufReadPost | |
| 263 and BufNewFile autocommands. But when the 'modified' option was set by the | |
| 264 autocommands, this doesn't happen. | |
| 265 | |
| 266 You can use the 'eventignore' option to ignore a number of events or all | |
| 267 events. | |
| 7 | 268 *autocommand-events* *{event}* |
| 269 Vim recognizes the following events. Vim ignores the case of event names | |
| 270 (e.g., you can use "BUFread" or "bufread" instead of "BufRead"). | |
| 271 | |
| 579 | 272 First an overview by function with a short explanation. Then the list |
| 843 | 273 alphabetically with full explanations |autocmd-events-abc|. |

451 during startup. |
| 579 | 452 The BufCreate event is for historic reasons. |
| 453 NOTE: When this autocommand is executed, the | |
| 454 current buffer "%" may be different from the | |
| 455 buffer being created "<afile>". | |
| 456 *BufDelete* | |
| 457 BufDelete Before deleting a buffer from the buffer list. | |
| 458 The BufUnload may be called first (if the | |
| 459 buffer was loaded). | |
| 460 Also used just before a buffer in the buffer | |
| 461 list is renamed. | |
| 462 NOTE: When this autocommand is executed, the | |
| 463 current buffer "%" may be different from the | |
| 1621 | 464 buffer being deleted "<afile>" and "<abuf>". |
| 1919 | 465 Don't change to another buffer, it will cause |
| 466 problems. | |
| 579 | 467 *BufEnter* |
| 468 BufEnter After entering a buffer. Useful for setting | |
| 469 options for a file type. Also executed when | |
| 470 starting to edit a buffer, after the | |
| 471 BufReadPost autocommands. | |
| 472 *BufFilePost* | |
| 473 BufFilePost After changing the name of the current buffer | |
| 474 with the ":file" or ":saveas" command. | |
| 625 | 475 *BufFilePre* |
| 579 | 476 BufFilePre Before changing the name of the current buffer |
| 477 with the ":file" or ":saveas" command. | |
| 478 *BufHidden* | |
| 17261 | 479 BufHidden Just before a buffer becomes hidden. That is, |
| 480 when there are no longer windows that show | |
| 579 | 481 the buffer, but the buffer is not unloaded or |
| 482 deleted. Not used for ":qa" or ":q" when | |
| 483 exiting Vim. | |
| 484 NOTE: When this autocommand is executed, the | |
| 485 current buffer "%" may be different from the | |
| 486 buffer being unloaded "<afile>". | |
| 487 *BufLeave* | |
| 488 BufLeave Before leaving to another buffer. Also when | |
| 489 leaving or closing the current window and the | |
| 490 new current window is not for the same buffer. | |
| 491 Not used for ":qa" or ":q" when exiting Vim. | |
| 492 *BufNew* | |
| 493 BufNew Just after creating a new buffer. Also used | |
| 494 just after a buffer has been renamed. When | |
| 495 the buffer is added to the buffer list BufAdd | |
| 496 will be triggered too. | |
| 497 NOTE: When this autocommand is executed, the | |
| 498 current buffer "%" may be different from the | |
| 499 buffer being created "<afile>". | |
| 7 | 500 *BufNewFile* |
| 501 BufNewFile When starting to edit a file that doesn't | |
| 502 exist. Can be used to read in a skeleton | |
| 503 file. | |
| 504 *BufRead* *BufReadPost* | |
| 505 BufRead or BufReadPost When starting to edit a new buffer, after | |
| 506 reading the file into the buffer, before | |
| 507 executing the modelines. See |BufWinEnter| | |
| 508 for when you need to do something after | |
| 509 processing the modelines. | |
| 28517 | 510 Also triggered: |
| 511 - when writing an unnamed buffer in a way that | |
| 512 the buffer gets a name | |
| 513 - after successfully recovering a file | |
| 514 - for the filetypedetect group when executing | |
| 515 ":filetype detect" | |
| 516 Not triggered: | |
| 517 - for the `:read file` command | |
| 518 - when the file doesn't exist | |
| 625 | 519 *BufReadCmd* |
| 7 | 520 BufReadCmd Before starting to edit a new buffer. Should |
| 521 read the file into the buffer. |Cmd-event| | |
| 625 | 522 *BufReadPre* *E200* *E201* |
| 579 | 523 BufReadPre When starting to edit a new buffer, before |
| 524 reading the file into the buffer. Not used | |
| 525 if the file doesn't exist. | |
| 526 *BufUnload* | |
| 527 BufUnload Before unloading a buffer. This is when the | |
| 528 text in the buffer is going to be freed. This | |
| 529 may be after a BufWritePost and before a | |
| 530 BufDelete. Also used for all buffers that are | |
| 531 loaded when Vim is going to exit. | |
| 532 NOTE: When this autocommand is executed, the | |
| 533 current buffer "%" may be different from the | |
| 534 buffer being unloaded "<afile>". | |

538 event is not triggered. |
| 579 | 539 *BufWinEnter* |
| 540 BufWinEnter After a buffer is displayed in a window. This | |
| 541 can be when the buffer is loaded (after | |
| 1621 | 542 processing the modelines) or when a hidden |
| 579 | 543 buffer is displayed in a window (and is no |
| 1621 | 544 longer hidden). |
| 545 Does not happen for |:split| without | |
| 546 arguments, since you keep editing the same | |
| 547 buffer, or ":split" with a file that's already | |
| 1668 | 548 open in a window, because it re-uses an |
| 549 existing buffer. But it does happen for a | |
| 550 ":split" with the name of the current buffer, | |
| 551 since it reloads that buffer. | |

| 558 Also triggered when exiting. It's triggered | |
| 559 before BufUnload or BufHidden. | |

| 579 | 565 *BufWipeout* |
| 566 BufWipeout Before completely deleting a buffer. The | |
| 567 BufUnload and BufDelete events may be called | |
| 568 first (if the buffer was loaded and was in the | |
| 569 buffer list). Also used just before a buffer | |
| 570 is renamed (also when it's not in the buffer | |
| 571 list). | |
| 572 NOTE: When this autocommand is executed, the | |
| 573 current buffer "%" may be different from the | |
| 574 buffer being deleted "<afile>". | |
| 1919 | 575 Don't change to another buffer, it will cause |
| 576 problems. | |
| 7 | 577 *BufWrite* *BufWritePre* |
| 578 BufWrite or BufWritePre Before writing the whole buffer to a file. | |
| 579 *BufWriteCmd* | |
| 580 BufWriteCmd Before writing the whole buffer to a file. | |
| 581 Should do the writing of the file and reset | |
| 39 | 582 'modified' if successful, unless '+' is in |
| 583 'cpo' and writing to another file |cpo-+|. | |
| 584 The buffer contents should not be changed. | |
| 3082 | 585 When the command resets 'modified' the undo |
| 586 information is adjusted to mark older undo | |
| 587 states as 'modified', like |:write| does. | |
| 39 | 588 |Cmd-event| |
| 579 | 589 *BufWritePost* |
| 590 BufWritePost After writing the whole buffer to a file | |
| 591 (should undo the commands for BufWritePre). | |
| 6154 | 592 *CmdUndefined* |
| 593 CmdUndefined When a user command is used but it isn't | |
| 594 defined. Useful for defining a command only | |
| 595 when it's used. The pattern is matched | |
| 596 against the command name. Both <amatch> and | |
| 597 <afile> are set to the name of the command. | |
| 598 NOTE: Autocompletion won't work until the | |
| 599 command is defined. An alternative is to | |
| 600 always define the user command and have it | |
| 601 invoke an autoloaded function. See |autoload|. | |

691 CompleteDonePre if you need it. |
| 6909 | 692 The |v:completed_item| variable contains |
| 693 information about the completed item. | |
| 3682 | 694 |
| 579 | 695 *CursorHold* |
| 696 CursorHold When the user doesn't press a key for the time | |
| 22441 | 697 specified with 'updatetime'. Not triggered |
| 579 | 698 until the user has pressed a key (i.e. doesn't |
| 699 fire every 'updatetime' ms if you leave Vim to | |
| 700 make some coffee. :) See |CursorHold-example| | |
| 701 for previewing tags. | |
| 702 This event is only triggered in Normal mode. | |
| 1154 | 703 It is not triggered when waiting for a command |
| 704 argument to be typed, or a movement after an | |
| 705 operator. | |
| 610 | 706 While recording the CursorHold event is not |
| 707 triggered. |q| | |
| 6259 | 708 *<CursorHold>* |
| 709 Internally the autocommand is triggered by the | |
| 710 <CursorHold> key. In an expression mapping | |
| 711 |getchar()| may see this character. | |
| 712 | |
| 579 | 713 Note: Interactive commands cannot be used for |
| 714 this event. There is no hit-enter prompt, | |
| 715 the screen is updated directly (when needed). | |
| 716 Note: In the future there will probably be | |
| 717 another option to set the time. | |
| 718 Hint: to force an update of the status lines | |
| 719 use: > | |
| 720 :let &ro = &ro | |
| 18972 | 721 < {only on Amiga, Unix, Win32 and all GUI |
| 579 | 722 versions} |

727 |insert_expand|. |
| 661 | 728 |
| 729 *CursorMoved* | |
| 4911 | 730 CursorMoved After the cursor was moved in Normal or Visual |
| 731 mode. Also when the text of the cursor line | |
| 732 has been changed, e.g., with "x", "rx" or "p". | |
| 28246 | 733 Not always triggered when there is typeahead, |
| 734 while executing commands in a script file, | |
| 735 when an operator is pending or when moving to | |
| 25161 | 736 another window while remaining at the same |
| 737 cursor position. | |
| 667 | 738 For an example see |match-parens|. |
| 16023 | 739 Note: This can not be skipped with |
| 740 `:noautocmd`. | |
| 4264 | 741 Careful: This is triggered very often, don't |
| 742 do anything that the user does not expect or | |
| 743 that is slow. | |
| 661 | 744 *CursorMovedI* |
| 745 CursorMovedI After the cursor was moved in Insert mode. | |
| 3082 | 746 Not triggered when the popup menu is visible. |
| 661 | 747 Otherwise the same as CursorMoved. |
| 28517 | 748 *DiffUpdated* |
| 749 DiffUpdated After diffs have been updated. Depending on | |
| 750 what kind of diff is being used (internal or | |
| 751 external) this can be triggered on every | |
| 752 change or when doing |:diffupdate|. | |
| 753 *DirChangedPre* | |
| 754 DirChangedPre The working directory is going to be changed, | |
| 755 as with |DirChanged|. The pattern is like | |
| 756 with |DirChanged|. The new directory can be | |
| 757 found in v:event.directory. | |
| 758 *DirChanged* | |
| 759 DirChanged The working directory has changed in response | |
| 760 to the |:cd| or |:tcd| or |:lcd| commands, or | |
| 761 as a result of the 'autochdir' option. | |
| 762 The pattern can be: | |
| 763 "window" to trigger on `:lcd` | |
| 764 "tabpage" to trigger on `:tcd` | |
| 765 "global" to trigger on `:cd` | |
| 766 "auto" to trigger on 'autochdir'. | |
| 767 "drop" to trigger on editing a file | |
| 768 <afile> is set to the new directory name. | |
| 579 | 769 *EncodingChanged* |
| 770 EncodingChanged Fires off after the 'encoding' option has been | |
| 771 changed. Useful to set up fonts, for example. | |
| 28517 | 772 *ExitPre* |
| 773 ExitPre When using `:quit`, `:wq` in a way it makes | |
| 774 Vim exit, or using `:qall`, just after | |
| 775 |QuitPre|. Can be used to close any | |
| 776 non-essential window. Exiting may still be | |
| 777 cancelled if there is a modified buffer that | |
| 778 isn't automatically saved, use |VimLeavePre| | |
| 779 for really exiting. | |
| 7 | 780 *FileAppendCmd* |
| 781 FileAppendCmd Before appending to a file. Should do the | |
| 26 | 782 appending to the file. Use the '[ and '] |
| 25973 | 783 marks for the range of lines. |Cmd-event| |
| 579 | 784 *FileAppendPost* |
| 785 FileAppendPost After appending to a file. | |
| 786 *FileAppendPre* | |
| 787 FileAppendPre Before appending to a file. Use the '[ and '] | |
| 788 marks for the range of lines. | |
| 789 *FileChangedRO* | |
| 790 FileChangedRO Before making the first change to a read-only | |
| 791 file. Can be used to check-out the file from | |
| 792 a source control system. Not triggered when | |
| 793 the change was caused by an autocommand. | |
| 794 This event is triggered when making the first | |
| 795 change in a buffer or the first change after | |
| 823 | 796 'readonly' was set, just before the change is |
| 797 applied to the text. | |
| 579 | 798 WARNING: If the autocommand moves the cursor |
| 799 the effect of the change is undefined. | |
| 819 | 800 *E788* |
| 801 It is not allowed to change to another buffer | |
| 802 here. You can reload the buffer but not edit | |
| 803 another one. | |

806 may fail and the change will be aborted. |
| 7 | 807 *FileChangedShell* |
| 808 FileChangedShell When Vim notices that the modification time of | |
| 809 a file has changed since editing started. | |
| 810 Also when the file attributes of the file | |
| 5908 | 811 change or when the size of the file changes. |
| 812 |timestamp| | |
| 7 | 813 Mostly triggered after executing a shell |
| 814 command, but also with a |:checktime| command | |
| 11473 | 815 or when gvim regains input focus. |
| 7 | 816 This autocommand is triggered for each changed |
| 817 file. It is not used when 'autoread' is set | |
| 818 and the buffer was not changed. If a | |
| 819 FileChangedShell autocommand is present the | |
| 820 warning message and prompt is not given. | |
| 179 | 821 The |v:fcs_reason| variable is set to indicate |
| 822 what happened and |v:fcs_choice| can be used | |
| 823 to tell Vim what to do next. | |
| 7 | 824 NOTE: When this autocommand is executed, the |
| 825 current buffer "%" may be different from the | |
| 11347 | 826 buffer that was changed, which is in "<afile>". |
| 7 | 827 NOTE: The commands must not change the current |
| 828 buffer, jump to another buffer or delete a | |

829 buffer. *E246* *E811* |
| 7 | 830 NOTE: This event never nests, to avoid an |
| 831 endless loop. This means that while executing | |
| 832 commands for the FileChangedShell event no | |
| 833 other FileChangedShell event will be | |
| 834 triggered. | |
| 766 | 835 *FileChangedShellPost* |
| 836 FileChangedShellPost After handling a file that was changed outside | |
| 837 of Vim. Can be used to update the statusline. | |
| 579 | 838 *FileEncoding* |
| 839 FileEncoding Obsolete. It still works and is equivalent | |
| 840 to |EncodingChanged|. | |
| 841 *FileReadCmd* | |
| 842 FileReadCmd Before reading a file with a ":read" command. | |
| 843 Should do the reading of the file. |Cmd-event| | |
| 844 *FileReadPost* | |
| 845 FileReadPost After reading a file with a ":read" command. | |
| 846 Note that Vim sets the '[ and '] marks to the | |
| 847 first and last line of the read. This can be | |
| 848 used to operate on the lines just read. | |
| 849 *FileReadPre* | |
| 850 FileReadPre Before reading a file with a ":read" command. | |
| 851 *FileType* | |
| 1154 | 852 FileType When the 'filetype' option has been set. The |
| 853 pattern is matched against the filetype. | |
| 579 | 854 <afile> can be used for the name of the file |

| 579 | 858 See |filetypes|. |
| 859 *FileWriteCmd* | |
| 860 FileWriteCmd Before writing to a file, when not writing the | |
| 861 whole buffer. Should do the writing to the | |
| 862 file. Should not change the buffer. Use the | |
| 863 '[ and '] marks for the range of lines. | |
| 864 |Cmd-event| | |
| 865 *FileWritePost* | |

| 869 FileWritePre Before writing to a file, when not writing the | |
| 870 whole buffer. Use the '[ and '] marks for the | |
| 871 range of lines. | |
| 872 *FilterReadPost* | |
| 873 FilterReadPost After reading a file from a filter command. | |
| 874 Vim checks the pattern against the name of | |
| 875 the current buffer as with FilterReadPre. | |
| 876 Not triggered when 'shelltemp' is off. | |
| 877 *FilterReadPre* *E135* | |
| 878 FilterReadPre Before reading a file from a filter command. | |
| 879 Vim checks the pattern against the name of | |
| 880 the current buffer, not the name of the | |
| 881 temporary file that is the output of the | |
| 882 filter command. | |
| 883 Not triggered when 'shelltemp' is off. | |
| 884 *FilterWritePost* | |
| 885 FilterWritePost After writing a file for a filter command or | |
| 15334 | 886 making a diff with an external diff (see |
| 25973 | 887 |DiffUpdated| for internal diff). |
| 579 | 888 Vim checks the pattern against the name of |

| 15334 | 893 making a diff with an external diff. |
| 579 | 894 Vim checks the pattern against the name of |
| 895 the current buffer, not the name of the | |
| 896 temporary file that is the output of the | |
| 897 filter command. | |
| 898 Not triggered when 'shelltemp' is off. | |
| 7 | 899 *FocusGained* |
| 900 FocusGained When Vim got input focus. Only for the GUI | |
| 901 version and a few console versions where this | |
| 902 can be detected. | |
| 903 *FocusLost* | |
| 904 FocusLost When Vim lost input focus. Only for the GUI | |
| 905 version and a few console versions where this | |
| 11 | 906 can be detected. May also happen when a |
| 907 dialog pops up. | |
| 7 | 908 *FuncUndefined* |
| 909 FuncUndefined When a user function is used but it isn't | |
| 910 defined. Useful for defining a function only | |
| 1154 | 911 when it's used. The pattern is matched |
| 912 against the function name. Both <amatch> and | |
| 913 <afile> are set to the name of the function. | |
| 23305 | 914 Not triggered when compiling a |Vim9| |
| 915 function. | |
| 6154 | 916 NOTE: When writing Vim scripts a better |
| 917 alternative is to use an autoloaded function. | |
| 161 | 918 See |autoload-functions|. |
| 579 | 919 *GUIEnter* |
| 920 GUIEnter After starting the GUI successfully, and after | |
| 921 opening the window. It is triggered before | |
| 922 VimEnter when using gvim. Can be used to | |
| 923 position the window from a .gvimrc file: > | |
| 924 :autocmd GUIEnter * winpos 100 50 | |
| 1154 | 925 < *GUIFailed* |
| 926 GUIFailed After starting the GUI failed. Vim may | |
| 927 continue to run in the terminal, if possible | |
| 928 (only on Unix and alikes, when connecting the | |
| 929 X server fails). You may want to quit Vim: > | |
| 930 :autocmd GUIFailed * qall | |
| 579 | 931 < *InsertChange* |
| 932 InsertChange When typing <Insert> while in Insert or | |
| 933 Replace mode. The |v:insertmode| variable | |
| 934 indicates the new mode. | |
| 935 Be careful not to move the cursor or do | |
| 936 anything else that the user does not expect. | |
| 2845 | 937 *InsertCharPre* |
| 938 InsertCharPre When a character is typed in Insert mode, | |
| 939 before inserting the char. | |
| 940 The |v:char| variable indicates the char typed | |
| 941 and can be changed during the event to insert | |
| 942 a different character. When |v:char| is set | |
| 943 to more than one character this text is | |
| 944 inserted literally. | |
| 945 It is not allowed to change the text |textlock|. | |
| 946 The event is not triggered when 'paste' is | |
| 13437 | 947 set. {only with the +eval feature} |
| 579 | 948 *InsertEnter* |
| 1154 | 949 InsertEnter Just before starting Insert mode. Also for |
| 950 Replace mode and Virtual Replace mode. The | |
| 579 | 951 |v:insertmode| variable indicates the mode. |
| 4448 | 952 Be careful not to do anything else that the |
| 953 user does not expect. | |
| 954 The cursor is restored afterwards. If you do | |
| 955 not want that set |v:char| to a non-empty | |
| 956 string. | |

| 1061 | 1128 *SourceCmd* |
| 1129 SourceCmd When sourcing a Vim script. |:source| | |
| 1130 <afile> is the name of the file being sourced. | |
| 1131 The autocommand must source this file. | |
| 1132 |Cmd-event| | |
| 650 | 1133 *SpellFileMissing* |
| 1134 SpellFileMissing When trying to load a spell checking file and | |
| 1061 | 1135 it can't be found. The pattern is matched |
| 1136 against the language. <amatch> is the | |
| 1137 language, 'encoding' also matters. See | |
| 650 | 1138 |spell-SpellFileMissing|. |
| 579 | 1139 *StdinReadPost* |
| 1140 StdinReadPost After reading from the stdin into the buffer, | |
| 1141 before executing the modelines. Only used | |
| 1142 when the "-" argument was used when Vim was | |
| 1143 started |--|. | |
| 1144 *StdinReadPre* | |
| 1145 StdinReadPre Before reading from stdin into the buffer. | |
| 1146 Only used when the "-" argument was used when | |
| 1147 Vim was started |--|. | |
| 1148 *SwapExists* | |
| 1149 SwapExists Detected an existing swap file when starting | |
| 1150 to edit a file. Only when it is possible to | |
| 1151 select a way to handle the situation, when Vim | |
| 1152 would ask the user what to do. | |
| 1153 The |v:swapname| variable holds the name of | |
| 590 | 1154 the swap file found, <afile> the file being |
| 1155 edited. |v:swapcommand| may contain a command | |
| 1156 to be executed in the opened file. | |
| 1157 The commands should set the |v:swapchoice| | |
| 1158 variable to a string with one character to | |
| 1159 tell Vim what should be done next: | |
| 579 | 1160 'o' open read-only |
| 1161 'e' edit the file anyway | |
| 1162 'r' recover | |
| 1163 'd' delete the swap file | |
| 1164 'q' quit, don't edit the file | |
| 1165 'a' abort, like hitting CTRL-C | |
| 1166 When set to an empty string the user will be | |
| 1167 asked, as if there was no SwapExists autocmd. | |
| 1919 | 1168 *E812* |
| 1169 It is not allowed to change to another buffer, | |
| 1170 change a buffer name or change directory | |
| 1171 here. | |
| 13437 | 1172 {only available with the +eval feature} |
| 579 | 1173 *Syntax* |
| 1154 | 1174 Syntax When the 'syntax' option has been set. The |
| 1175 pattern is matched against the syntax name. | |
| 579 | 1176 <afile> can be used for the name of the file |
| 1177 where this option was set, and <amatch> for | |
| 1178 the new value of 'syntax'. | |
| 1179 See |:syn-on|. | |

1415 The {aupat} argument of `:autocmd` can be a comma-separated list. This works as |
| 27162 | 1416 if the command was given with each pattern separately. Thus this command: > |
| 6741 | 1417 :autocmd BufRead *.txt,*.info set et |
| 1418 Is equivalent to: > | |
| 1419 :autocmd BufRead *.txt set et | |
| 1420 :autocmd BufRead *.info set et | |
| 1421 | |
| 27162 | 1422 The file pattern {aupat} is tested for a match against the file name in one of |
| 7 | 1423 two ways: |
| 1424 1. When there is no '/' in the pattern, Vim checks for a match against only | |
| 1425 the tail part of the file name (without its leading directory path). | |

1428 it to a full path and resolving symbolic links). |
| 7 | 1429 |
| 40 | 1430 The special pattern <buffer> or <buffer=N> is used for buffer-local |
| 1431 autocommands |autocmd-buflocal|. This pattern is not matched against the name | |
| 1432 of a buffer. | |
| 1433 | |
| 7 | 1434 Examples: > |
| 1435 :autocmd BufRead *.txt set et | |
| 1436 Set the 'et' option for all text files. > | |
| 1437 | |
| 1438 :autocmd BufRead /vim/src/*.c set cindent | |
| 1439 Set the 'cindent' option for C files in the /vim/src directory. > | |
| 1440 | |
| 1441 :autocmd BufRead /tmp/*.c set ts=5 | |
| 1442 If you have a link from "/tmp/test.c" to "/home/nobody/vim/src/test.c", and | |
| 1443 you start editing "/tmp/test.c", this autocommand will match. | |
| 1444 | |
| 1445 Note: To match part of a path, but not from the root directory, use a '*' as | |
| 1446 the first character. Example: > | |
| 1447 :autocmd BufRead */doc/*.txt set tw=78 | |
| 1448 This autocommand will for example be executed for "/tmp/doc/xx.txt" and | |
| 1449 "/usr/home/piet/doc/yy.txt". The number of directories does not matter here. | |
| 1450 | |
| 1451 | |
| 1452 The file name that the pattern is matched against is after expanding | |
| 1621 | 1453 wildcards. Thus if you issue this command: > |
| 7 | 1454 :e $ROOTDIR/main.$EXT |
| 1455 The argument is first expanded to: > | |
| 1456 /usr/root/main.py | |
| 1457 Before it's matched with the pattern of the autocommand. Careful with this | |
| 1458 when using events like FileReadCmd, the value of <amatch> may not be what you | |
| 1459 expect. | |
| 1460 | |
| 1461 | |
| 1462 Environment variables can be used in a pattern: > | |
| 1463 :autocmd BufRead $VIMRUNTIME/doc/*.txt set expandtab | |
| 1464 And ~ can be used for the home directory (if $HOME is defined): > | |
| 1465 :autocmd BufWritePost ~/.vimrc so ~/.vimrc | |
| 1466 :autocmd BufRead ~archive/* set readonly | |
| 1467 The environment variable is expanded when the autocommand is defined, not when | |
| 1468 the autocommand is executed. This is different from the command! | |
| 1469 | |
| 1470 *file-pattern* | |
| 1471 The pattern is interpreted like mostly used in file names: | |
| 5294 | 1472 * matches any sequence of characters; Unusual: includes path |
| 5277 | 1473 separators |
| 7 | 1474 ? matches any single character |
| 1475 \? matches a '?' | |
| 1476 . matches a '.' | |
| 1477 ~ matches a '~' | |
| 1478 , separates patterns | |
| 1479 \, matches a ',' | |
| 1480 { } like \( \) in a |pattern| | |
| 1481 , inside { }: like \| in a |pattern| | |

| 40 | 1496 *autocmd-changes* |
| 7 | 1497 Matching with the pattern is done when an event is triggered. Changing the |
| 1498 buffer name in one of the autocommands, or even deleting the buffer, does not | |
| 1499 change which autocommands will be executed. Example: > | |
| 1500 | |
| 1501 au BufEnter *.foo bdel | |
| 1502 au BufEnter *.foo set modified | |
| 1503 | |
| 1504 This will delete the current buffer and then set 'modified' in what has become | |
| 1505 the current buffer instead. Vim doesn't take into account that "*.foo" | |
| 1506 doesn't match with that buffer name. It matches "*.foo" with the name of the | |
| 1507 buffer at the moment the event was triggered. | |
| 1508 | |
| 40 | 1509 However, buffer-local autocommands will not be executed for a buffer that has |
| 1510 been wiped out with |:bwipe|. After deleting the buffer with |:bdel| the | |
| 1511 buffer actually still exists (it becomes unlisted), thus the autocommands are | |
| 1512 still executed. | |
| 1513 | |
| 7 | 1514 ============================================================================== |
| 856 | 1515 7. Buffer-local autocommands *autocmd-buflocal* *autocmd-buffer-local* |
| 1516 *<buffer=N>* *<buffer=abuf>* *E680* | |
| 40 | 1517 |
| 1518 Buffer-local autocommands are attached to a specific buffer. They are useful | |
| 1519 if the buffer does not have a name and when the name does not match a specific | |
| 1520 pattern. But it also means they must be explicitly added to each buffer. | |
| 1521 | |
| 1522 Instead of a pattern buffer-local autocommands use one of these forms: | |
| 1523 <buffer> current buffer | |
| 1524 <buffer=99> buffer number 99 | |
| 1525 <buffer=abuf> using <abuf> (only when executing autocommands) | |
| 1526 |<abuf>| | |
| 1527 | |
| 1528 Examples: > | |
| 1529 :au CursorHold <buffer> echo 'hold' | |
| 1530 :au CursorHold <buffer=33> echo 'hold' | |

1531 :au BufNewFile * au CursorHold <buffer=abuf> echo 'hold' |
| 40 | 1532 |
| 1533 All the commands for autocommands also work with buffer-local autocommands, | |
| 1534 simply use the special string instead of the pattern. Examples: > | |
| 856 | 1535 :au! * <buffer> " remove buffer-local autocommands for |
| 1536 " current buffer | |
| 1537 :au! * <buffer=33> " remove buffer-local autocommands for | |
| 1538 " buffer #33 | |
| 1621 | 1539 :bufdo :au! CursorHold <buffer> " remove autocmd for given event for all |
| 856 | 1540 " buffers |
| 1541 :au * <buffer> " list buffer-local autocommands for | |
| 1542 " current buffer | |
| 40 | 1543 |
| 1544 Note that when an autocommand is defined for the current buffer, it is stored | |
| 1545 with the buffer number. Thus it uses the form "<buffer=12>", where 12 is the | |
| 1546 number of the current buffer. You will see this when listing autocommands, | |
| 1547 for example. | |
| 1548 | |
| 1549 To test for presence of buffer-local autocommands use the |exists()| function | |
| 1550 as follows: > | |
| 1551 :if exists("#CursorHold#<buffer=12>") | ... | endif | |
| 1552 :if exists("#CursorHold#<buffer>") | ... | endif " for current buffer | |
| 1553 | |
| 1554 When a buffer is wiped out its buffer-local autocommands are also gone, of | |
| 1555 course. Note that when deleting a buffer, e.g., with ":bdel", it is only | |
| 1556 unlisted, the autocommands are still present. In order to see the removal of | |
| 1557 buffer-local autocommands: > | |
| 1558 :set verbose=6 | |
| 1559 | |
| 1560 It is not possible to define buffer-local autocommands for a non-existent | |
| 1561 buffer. | |
| 1562 | |
| 1563 ============================================================================== | |
| 1564 8. Groups *autocmd-groups* | |
| 7 | 1565 |
| 1566 Autocommands can be put together in a group. This is useful for removing or | |
| 1567 executing a group of autocommands. For example, all the autocommands for | |
| 1568 syntax highlighting are put in the "highlight" group, to be able to execute | |
| 1569 ":doautoall highlight BufRead" when the GUI starts. | |
| 1570 | |
| 1571 When no specific group is selected, Vim uses the default group. The default | |
| 1572 group does not have a name. You cannot execute the autocommands from the | |
| 1573 default group separately; you can execute them only by executing autocommands | |
| 1574 for all groups. | |
| 1575 | |
| 1576 Normally, when executing autocommands automatically, Vim uses the autocommands | |
| 1577 for all groups. The group only matters when executing autocommands with | |
| 1578 ":doautocmd" or ":doautoall", or when defining or deleting autocommands. | |
| 1579 | |
| 1580 The group name can contain any characters except white space. The group name | |
| 1581 "end" is reserved (also in uppercase). | |
| 1582 | |
| 1583 The group name is case sensitive. Note that this is different from the event | |
| 1584 name! | |
| 1585 | |
| 1586 *:aug* *:augroup* | |
| 1587 :aug[roup] {name} Define the autocmd group name for the | |
| 1588 following ":autocmd" commands. The name "end" | |
| 1589 or "END" selects the default group. | |

1597 this group! You will get a warning if doing |
| 21676 | 1598 it anyway. When the group is the current |
| 1599 group you will get error E936. | |
| 7 | 1600 |
| 1601 To enter autocommands for a specific group, use this method: | |
| 1602 1. Select the group with ":augroup {name}". | |
| 1603 2. Delete any old autocommands with ":au!". | |
| 1604 3. Define the autocommands. | |
| 1605 4. Go back to the default group with "augroup END". | |
| 1606 | |
| 1607 Example: > | |
| 1608 :augroup uncompress | |
| 1609 : au! | |
| 1610 : au BufEnter *.gz %!gunzip | |
| 1611 :augroup END | |
| 1612 | |
| 1613 This prevents having the autocommands defined twice (e.g., after sourcing the | |
| 1614 .vimrc file again). | |
| 1615 | |
| 25880 | 1616 *FileExplorer* |
| 1617 There is one group that is recognized by Vim: FileExplorer. If this group | |
| 1618 exists Vim assumes that editing a directory is possible and will trigger a | |
| 1619 plugin that lists the files in that directory. This is used by the |netrw| | |
| 1620 plugin. This allows you to do: > | |
| 1621 browse edit | |
| 1622 | |
| 7 | 1623 ============================================================================== |
| 40 | 1624 9. Executing autocommands *autocmd-execute* |
| 7 | 1625 |
| 1626 Vim can also execute Autocommands non-automatically. This is useful if you | |
| 1627 have changed autocommands, or when Vim has executed the wrong autocommands | |
| 1628 (e.g., the file pattern match was wrong). | |
| 1629 | |
| 1630 Note that the 'eventignore' option applies here too. Events listed in this | |
| 1631 option will not cause any commands to be executed. | |
| 1632 | |
| 16944 | 1633 *:do* *:doau* *:doaut* *:doautocmd* *E217* |
| 3356 | 1634 :do[autocmd] [<nomodeline>] [group] {event} [fname] |
| 7 | 1635 Apply the autocommands matching [fname] (default: |
| 1636 current file name) for {event} to the current buffer. | |
| 1637 You can use this when the current file name does not | |
| 1638 match the right pattern, after changing settings, or | |
| 1639 to execute autocommands for a certain event. | |
| 1640 It's possible to use this inside an autocommand too, | |
| 1641 so you can base the autocommands for one extension on | |
| 1642 another extension. Example: > | |
| 3224 | 1643 :au BufEnter *.cpp so ~/.vimrc_cpp |
| 1644 :au BufEnter *.cpp doau BufEnter x.c | |
| 7 | 1645 < Be careful to avoid endless loops. See |
| 1646 |autocmd-nested|. | |
| 1647 | |
| 1648 When the [group] argument is not given, Vim executes | |
| 1649 the autocommands for all groups. When the [group] | |
| 1650 argument is included, Vim executes only the matching | |
| 1651 autocommands for that group. Note: if you use an | |
| 1652 undefined group name, Vim gives you an error message. | |
| 3350 | 1653 *<nomodeline>* |
| 1654 After applying the autocommands the modelines are | |
| 1655 processed, so that their settings overrule the | |
| 1656 settings from autocommands, like what happens when | |
| 1657 editing a file. This is skipped when the <nomodeline> | |
| 1658 argument is present. You probably want to use | |
| 1659 <nomodeline> for events that are not used when loading | |
| 1660 a buffer, such as |User|. | |

1662 matching autocommands were executed. |
| 7 | 1663 |
| 1664 *:doautoa* *:doautoall* | |
| 3342 | 1665 :doautoa[ll] [<nomodeline>] [group] {event} [fname] |
| 7 | 1666 Like ":doautocmd", but apply the autocommands to each |
| 24278 | 1667 loaded buffer. The current buffer is done last. |
| 1668 | |
| 1669 Note that [fname] is used to select the autocommands, | |
| 24569 | 1670 not the buffers to which they are applied. Example: > |
| 1671 augroup mine | |
| 1672 autocmd! | |
| 1673 autocmd FileType * echo expand('<amatch>') | |
| 1674 augroup END | |
| 1675 doautoall mine FileType Loaded-Buffer | |
| 1676 < Sourcing this script, you'll see as many | |
| 1677 "Loaded-Buffer" echoed as there are loaded buffers. | |
| 24278 | 1678 |
| 7 | 1679 Careful: Don't use this for autocommands that delete a |
| 1680 buffer, change to another buffer or change the | |
| 1681 contents of a buffer; the result is unpredictable. | |
| 1682 This command is intended for autocommands that set | |
| 1683 options, change highlighting, and things like that. | |
| 1684 | |
| 1685 ============================================================================== | |
| 40 | 1686 10. Using autocommands *autocmd-use* |
| 7 | 1687 |
| 1688 For WRITING FILES there are four possible sets of events. Vim uses only one | |
| 1689 of these sets for a write command: | |
| 1690 | |
| 1691 BufWriteCmd BufWritePre BufWritePost writing the whole buffer | |
| 1692 FilterWritePre FilterWritePost writing to filter temp file | |
| 1693 FileAppendCmd FileAppendPre FileAppendPost appending to a file | |
| 1694 FileWriteCmd FileWritePre FileWritePost any other file write | |
| 1695 | |
| 1696 When there is a matching "*Cmd" autocommand, it is assumed it will do the | |
| 1697 writing. No further writing is done and the other events are not triggered. | |
| 1698 |Cmd-event| | |
| 1699 | |
| 1700 Note that the *WritePost commands should undo any changes to the buffer that | |
| 1701 were caused by the *WritePre commands; otherwise, writing the file will have | |
| 1702 the side effect of changing the buffer. | |
| 1703 | |
| 1704 Before executing the autocommands, the buffer from which the lines are to be | |
| 1705 written temporarily becomes the current buffer. Unless the autocommands | |
| 1706 change the current buffer or delete the previously current buffer, the | |
| 1707 previously current buffer is made the current buffer again. | |
| 1708 | |
| 1709 The *WritePre and *AppendPre autocommands must not delete the buffer from | |
| 1710 which the lines are to be written. | |
| 1711 | |
| 1712 The '[ and '] marks have a special position: | |
| 1713 - Before the *ReadPre event the '[ mark is set to the line just above where | |
| 1714 the new lines will be inserted. | |
| 1715 - Before the *ReadPost event the '[ mark is set to the first line that was | |
| 1716 just read, the '] mark to the last line. | |
| 26 | 1717 - Before executing the *WriteCmd, *WritePre and *AppendPre autocommands the '[ |
| 1718 mark is set to the first line that will be written, the '] mark to the last | |
| 1719 line. | |
| 7 | 1720 Careful: '[ and '] change when using commands that change the buffer. |
| 1721 | |
| 1722 In commands which expect a file name, you can use "<afile>" for the file name | |
| 1723 that is being read |:<afile>| (you can also use "%" for the current file | |
| 1724 name). "<abuf>" can be used for the buffer number of the currently effective | |
| 14123 | 1725 buffer. This also works for buffers that don't have a name. But it doesn't |
| 7 | 1726 work for files without a buffer (e.g., with ":r file"). |
| 1727 | |
| 1728 *gzip-example* | |
| 1729 Examples for reading and writing compressed files: > | |
| 1730 :augroup gzip | |
| 1731 : autocmd! | |
| 1732 : autocmd BufReadPre,FileReadPre *.gz set bin | |
| 1733 : autocmd BufReadPost,FileReadPost *.gz '[,']!gunzip | |
| 1734 : autocmd BufReadPost,FileReadPost *.gz set nobin | |
| 27903 | 1735 : autocmd BufReadPost,FileReadPost *.gz execute ":doautocmd BufReadPost " .. expand("%:r") |
| 7 | 1736 : autocmd BufWritePost,FileWritePost *.gz !mv <afile> <afile>:r |
| 1737 : autocmd BufWritePost,FileWritePost *.gz !gzip <afile>:r | |
| 1738 | |
| 1739 : autocmd FileAppendPre *.gz !gunzip <afile> | |
| 1740 : autocmd FileAppendPre *.gz !mv <afile>:r <afile> | |
| 1741 : autocmd FileAppendPost *.gz !mv <afile> <afile>:r | |
| 1742 : autocmd FileAppendPost *.gz !gzip <afile>:r | |
| 1743 :augroup END | |
| 1744 | |
| 1745 The "gzip" group is used to be able to delete any existing autocommands with | |
| 1746 ":autocmd!", for when the file is sourced twice. | |
| 1747 | |
| 1748 ("<afile>:r" is the file name without the extension, see |:_%:|) | |
| 1749 | |
| 1750 The commands executed for the BufNewFile, BufRead/BufReadPost, BufWritePost, | |
| 1751 FileAppendPost and VimLeave events do not set or reset the changed flag of the | |
| 1752 buffer. When you decompress the buffer with the BufReadPost autocommands, you | |
| 1753 can still exit with ":q". When you use ":undo" in BufWritePost to undo the | |
| 1754 changes made by BufWritePre commands, you can still do ":q" (this also makes | |
| 1755 "ZZ" work). If you do want the buffer to be marked as modified, set the | |
| 1756 'modified' option. | |
| 1757 | |
| 1758 To execute Normal mode commands from an autocommand, use the ":normal" | |
| 1759 command. Use with care! If the Normal mode command is not finished, the user | |
| 1760 needs to type characters (e.g., after ":normal m" you need to type a mark | |
| 1761 name). | |
| 1762 | |
| 1763 If you want the buffer to be unmodified after changing it, reset the | |
| 1764 'modified' option. This makes it possible to exit the buffer with ":q" | |
| 1765 instead of ":q!". | |
| 1766 | |
| 1767 *autocmd-nested* *E218* | |
| 16023 | 1768 By default, autocommands do not nest. For example, if you use ":e" or ":w" in |
| 1769 an autocommand, Vim does not execute the BufRead and BufWrite autocommands for | |
| 7 | 1770 those commands. If you do want this, use the "nested" flag for those commands |
| 1771 in which you want nesting. For example: > | |

patch 8.1.1113: making an autocommand trigger once is not so easy

1772 :autocmd FileChangedShell *.c ++nested e! |
| 7 | 1773 The nesting is limited to 10 levels to get out of recursive loops. |
| 1774 | |
| 1775 It's possible to use the ":au" command in an autocommand. This can be a | |
| 1776 self-modifying command! This can be useful for an autocommand that should | |
| 1777 execute only once. | |
| 1778 | |
| 590 | 1779 If you want to skip autocommands for one command, use the |:noautocmd| command |
| 1780 modifier or the 'eventignore' option. | |
| 7 | 1781 |
| 1782 Note: When reading a file (with ":read file" or with a filter command) and the | |
| 1783 last line in the file does not have an <EOL>, Vim remembers this. At the next | |
| 1784 write (with ":write file" or with a filter command), if the same line is | |
| 1785 written again as the last line in a file AND 'binary' is set, Vim does not | |
| 1786 supply an <EOL>. This makes a filter command on the just read lines write the | |
| 1787 same file as was read, and makes a write command on just filtered lines write | |
| 1788 the same file as was read from the filter. For example, another way to write | |
| 1789 a compressed file: > | |
| 1790 | |
| 1791 :autocmd FileWritePre *.gz set bin|'[,']!gzip | |
| 1792 :autocmd FileWritePost *.gz undo|set nobin | |
| 1793 < | |
| 1794 *autocommand-pattern* | |
| 1795 You can specify multiple patterns, separated by commas. Here are some | |
| 1796 examples: > | |
| 1797 | |
| 1798 :autocmd BufRead * set tw=79 nocin ic infercase fo=2croq | |
| 1799 :autocmd BufRead .letter set tw=72 fo=2tcrq | |
| 1800 :autocmd BufEnter .letter set dict=/usr/lib/dict/words | |
| 1801 :autocmd BufLeave .letter set dict= | |
| 1802 :autocmd BufRead,BufNewFile *.c,*.h set tw=0 cin noic | |
| 1803 :autocmd BufEnter *.c,*.h abbr FOR for (i = 0; i < 3; ++i)<CR>{<CR>}<Esc>O | |
| 1804 :autocmd BufLeave *.c,*.h unabbr FOR | |
| 1805 | |
| 1806 For makefiles (makefile, Makefile, imakefile, makefile.unix, etc.): > | |
| 1807 | |
| 1808 :autocmd BufEnter ?akefile* set include=^s\=include | |
| 1809 :autocmd BufLeave ?akefile* set include& | |
| 1810 | |
| 1811 To always start editing C files at the first function: > | |
| 1812 | |
| 1813 :autocmd BufRead *.c,*.h 1;/^{ | |
| 1814 | |
| 1815 Without the "1;" above, the search would start from wherever the file was | |
| 1816 entered, rather than from the start of the file. | |
| 1817 | |
| 1818 *skeleton* *template* | |
| 1819 To read a skeleton (template) file when opening a new file: > | |
| 1820 | |
| 1821 :autocmd BufNewFile *.c 0r ~/vim/skeleton.c | |
| 1822 :autocmd BufNewFile *.h 0r ~/vim/skeleton.h | |
| 1823 :autocmd BufNewFile *.java 0r ~/vim/skeleton.java | |
| 1824 | |
| 1825 To insert the current date and time in a *.html file when writing it: > | |
| 1826 | |
| 1827 :autocmd BufWritePre,FileWritePre *.html ks|call LastMod()|'s | |
| 1828 :fun LastMod() | |
| 1829 : if line("$") > 20 | |
| 1830 : let l = 20 | |
| 1831 : else | |
| 1832 : let l = line("$") | |
| 1833 : endif | |
| 27903 | 1834 : exe "1," .. l .. "g/Last modified: /s/Last modified: .*/Last modified: " .. |
| 7 | 1835 : \ strftime("%Y %b %d") |
| 1836 :endfun | |
| 1837 | |
| 1838 You need to have a line "Last modified: <date time>" in the first 20 lines | |
| 1839 of the file for this to work. Vim replaces <date time> (and anything in the | |
| 1840 same line after it) with the current date and time. Explanation: | |
| 1841 ks mark current position with mark 's' | |
| 1842 call LastMod() call the LastMod() function to do the work | |
| 1843 's return the cursor to the old position | |
| 1844 The LastMod() function checks if the file is shorter than 20 lines, and then | |
| 1845 uses the ":g" command to find lines that contain "Last modified: ". For those | |
| 1846 lines the ":s" command is executed to replace the existing date with the | |
| 1847 current one. The ":execute" command is used to be able to use an expression | |
| 1848 for the ":g" and ":s" commands. The date is obtained with the strftime() | |
| 1849 function. You can change its argument to get another date string. | |
| 1850 | |
| 1851 When entering :autocmd on the command-line, completion of events and command | |
| 1852 names may be done (with <Tab>, CTRL-D, etc.) where appropriate. | |
| 1853 | |
| 1854 Vim executes all matching autocommands in the order that you specify them. | |
| 1855 It is recommended that your first autocommand be used for all files by using | |
| 1856 "*" as the file pattern. This means that you can define defaults you like | |
| 1857 here for any settings, and if there is another matching autocommand it will | |
| 1858 override these. But if there is no other matching autocommand, then at least | |
| 1859 your default settings are recovered (if entering this file from another for | |
| 1860 which autocommands did match). Note that "*" will also match files starting | |
| 1861 with ".", unlike Unix shells. | |
| 1862 | |
| 1863 *autocmd-searchpat* | |
| 1864 Autocommands do not change the current search patterns. Vim saves the current | |
| 1865 search patterns before executing autocommands then restores them after the | |
| 1866 autocommands finish. This means that autocommands do not affect the strings | |
| 1867 highlighted with the 'hlsearch' option. Within autocommands, you can still | |
| 1868 use search patterns normally, e.g., with the "n" command. | |
| 1869 If you want an autocommand to set the search pattern, such that it is used | |
| 1870 after the autocommand finishes, use the ":let @/ =" command. | |
| 1871 The search-highlighting cannot be switched off with ":nohlsearch" in an | |
| 1872 autocommand. Use the 'h' flag in the 'viminfo' option to disable search- | |
| 1873 highlighting when starting Vim. | |
| 1874 | |
| 1875 *Cmd-event* | |
| 1876 When using one of the "*Cmd" events, the matching autocommands are expected to | |
| 1061 | 1877 do the file reading, writing or sourcing. This can be used when working with |
| 1878 a special kind of file, for example on a remote system. | |
| 7 | 1879 CAREFUL: If you use these events in a wrong way, it may have the effect of |
| 1880 making it impossible to read or write the matching files! Make sure you test | |
| 1881 your autocommands properly. Best is to use a pattern that will never match a | |
| 1882 normal file name, for example "ftp://*". | |
| 1883 | |
| 1884 When defining a BufReadCmd it will be difficult for Vim to recover a crashed | |
| 1885 editing session. When recovering from the original file, Vim reads only those | |
| 1886 parts of a file that are not found in the swap file. Since that is not | |
| 1887 possible with a BufReadCmd, use the |:preserve| command to make sure the | |
| 1888 original file isn't needed for recovery. You might want to do this only when | |
| 1889 you expect the file to be modified. | |
| 1890 | |
| 1061 | 1891 For file read and write commands the |v:cmdarg| variable holds the "++enc=" |
| 1892 and "++ff=" argument that are effective. These should be used for the command | |
| 1893 that reads/writes the file. The |v:cmdbang| variable is one when "!" was | |
| 1894 used, zero otherwise. | |

| 1899 11. Disabling autocommands *autocmd-disable* | |
| 1900 | |
| 1901 To disable autocommands for some time use the 'eventignore' option. Note that | |
| 1902 this may cause unexpected behavior, make sure you restore 'eventignore' | |
| 1903 afterwards, using a |:try| block with |:finally|. | |
| 1904 | |
| 1905 *:noautocmd* *:noa* | |
| 1906 To disable autocommands for just one command use the ":noautocmd" command | |
| 1907 modifier. This will set 'eventignore' to "all" for the duration of the | |
| 1908 following command. Example: > | |
| 1909 | |
| 1910 :noautocmd w fname.gz | |
| 1911 | |
| 1912 This will write the file without triggering the autocommands defined by the | |
| 1913 gzip plugin. | |
| 1914 | |
| 16023 | 1915 Note that some autocommands are not triggered right away, but only later. |
| 1916 This specifically applies to |CursorMoved| and |TextChanged|. | |
