| 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. | |
| 49 | |

| 7 | 86 Note that special characters (e.g., "%", "<cword>") in the ":autocmd" |
| 87 arguments are not expanded when the autocommand is defined. These will be | |
| 88 expanded when the Event is recognized, and the {cmd} is executed. The only | |
| 89 exception is that "<sfile>" is expanded when the autocmd is defined. Example: | |
| 90 > | |
| 91 :au BufNewFile,BufRead *.html so <sfile>:h/html.vim | |
| 92 | |
| 93 Here Vim expands <sfile> to the name of the file containing this line. | |

104 augroup END |
| 7 | 105 |
| 106 If you don't want to remove all autocommands, you can instead use a variable | |
| 107 to ensure that Vim includes the autocommands only once: > | |
| 108 | |
| 109 :if !exists("autocommands_loaded") | |
| 110 : let autocommands_loaded = 1 | |
| 111 : au ... | |
| 112 :endif | |
| 113 | |
| 114 When the [group] argument is not given, Vim uses the current group (as defined | |
| 115 with ":augroup"); otherwise, Vim uses the group defined with [group]. Note | |
| 116 that [group] must have been defined before. You cannot define a new group | |
| 117 with ":au group ..."; use ":augroup" for that. | |
| 118 | |
| 119 While testing autocommands, you might find the 'verbose' option to be useful: > | |
| 120 :set verbose=9 | |
| 121 This setting makes Vim echo the autocommands as it executes them. | |
| 122 | |
| 123 When defining an autocommand in a script, it will be able to call functions | |
| 124 local to the script and use mappings local to the script. When the event is | |
| 125 triggered and the command executed, it will run in the context of the script | |
| 126 it was defined in. This matters if |<SID>| is used in a command. | |
| 127 | |
| 1621 | 128 When executing the commands, the message from one command overwrites a |
| 7 | 129 previous message. This is different from when executing the commands |
| 130 manually. Mostly the screen will not scroll up, thus there is no hit-enter | |
| 131 prompt. When one command outputs two messages this can happen anyway. | |

160 group, it breaks plugins, syntax highlighting, etc. |
| 7 | 161 |
| 162 When the [group] argument is not given, Vim uses the current group (as defined | |
| 163 with ":augroup"); otherwise, Vim uses the group defined with [group]. | |
| 164 | |
| 165 ============================================================================== | |
| 166 4. Listing autocommands *autocmd-list* | |
| 167 | |
| 168 :au[tocmd] [group] {event} {pat} | |
| 169 Show the autocommands associated with {event} and | |
| 170 {pat}. | |
| 171 | |
| 172 :au[tocmd] [group] * {pat} | |
| 173 Show the autocommands associated with {pat} for all | |
| 174 events. | |
| 175 | |
| 176 :au[tocmd] [group] {event} | |
| 177 Show all autocommands for {event}. | |
| 178 | |
| 179 :au[tocmd] [group] Show all autocommands. | |
| 180 | |
| 181 If you provide the [group] argument, Vim lists only the autocommands for | |
| 182 [group]; otherwise, Vim lists the autocommands for ALL groups. Note that this | |
| 183 argument behavior differs from that for defining and removing autocommands. | |
| 184 | |
| 40 | 185 In order to list buffer-local autocommands, use a pattern in the form <buffer> |
| 186 or <buffer=N>. See |autocmd-buflocal|. | |
| 187 | |
| 500 | 188 *:autocmd-verbose* |
| 189 When 'verbose' is non-zero, listing an autocommand will also display where it | |
| 190 was last defined. Example: > | |
| 191 | |
| 192 :verbose autocmd BufEnter | |
| 193 FileExplorer BufEnter | |
| 856 | 194 * call s:LocalBrowse(expand("<amatch>")) |
| 500 | 195 Last set from /usr/share/vim/vim-7.0/plugin/NetrwPlugin.vim |
| 196 < | |
| 197 See |:verbose-cmd| for more information. | |
| 198 | |
| 7 | 199 ============================================================================== |
| 200 5. Events *autocmd-events* *E215* *E216* | |
| 201 | |
| 579 | 202 You can specify a comma-separated list of event names. No white space can be |
| 203 used in this list. The command applies to all the events in the list. | |
| 204 | |
| 205 For READING FILES there are four kinds of events possible: | |
| 206 BufNewFile starting to edit a non-existent file | |
| 207 BufReadPre BufReadPost starting to edit an existing file | |
| 208 FilterReadPre FilterReadPost read the temp file with filter output | |
| 209 FileReadPre FileReadPost any other file read | |
| 210 Vim uses only one of these four kinds when reading a file. The "Pre" and | |
| 211 "Post" events are both triggered, before and after reading the file. | |
| 212 | |
| 213 Note that the autocommands for the *ReadPre events and all the Filter events | |
| 214 are not allowed to change the current buffer (you will get an error message if | |
| 215 this happens). This is to prevent the file to be read into the wrong buffer. | |
| 216 | |
| 217 Note that the 'modified' flag is reset AFTER executing the BufReadPost | |
| 218 and BufNewFile autocommands. But when the 'modified' option was set by the | |
| 219 autocommands, this doesn't happen. | |
| 220 | |
| 221 You can use the 'eventignore' option to ignore a number of events or all | |
| 222 events. | |
| 7 | 223 *autocommand-events* *{event}* |
| 224 Vim recognizes the following events. Vim ignores the case of event names | |
| 225 (e.g., you can use "BUFread" or "bufread" instead of "BufRead"). | |
| 226 | |
| 579 | 227 First an overview by function with a short explanation. Then the list |
| 843 | 228 alphabetically with full explanations |autocmd-events-abc|. |

| 232 Reading | |
| 233 |BufNewFile| starting to edit a file that doesn't exist | |
| 234 |BufReadPre| starting to edit a new buffer, before reading the file | |
| 235 |BufRead| starting to edit a new buffer, after reading the file | |
| 236 |BufReadPost| starting to edit a new buffer, after reading the file | |

| 374 | |
| 375 The alphabetical list of autocommand events: *autocmd-events-abc* | |
| 376 | |
| 377 *BufCreate* *BufAdd* | |
| 378 BufAdd or BufCreate Just after creating a new buffer which is | |
| 379 added to the buffer list, or adding a buffer | |
| 380 to the buffer list. | |
| 381 Also used just after a buffer in the buffer | |
| 382 list has been renamed. | |
| 383 The BufCreate event is for historic reasons. | |
| 384 NOTE: When this autocommand is executed, the | |
| 385 current buffer "%" may be different from the | |
| 386 buffer being created "<afile>". | |
| 387 *BufDelete* | |
| 388 BufDelete Before deleting a buffer from the buffer list. | |
| 389 The BufUnload may be called first (if the | |
| 390 buffer was loaded). | |
| 391 Also used just before a buffer in the buffer | |
| 392 list is renamed. | |
| 393 NOTE: When this autocommand is executed, the | |
| 394 current buffer "%" may be different from the | |
| 1621 | 395 buffer being deleted "<afile>" and "<abuf>". |
| 1919 | 396 Don't change to another buffer, it will cause |
| 397 problems. | |
| 579 | 398 *BufEnter* |
| 399 BufEnter After entering a buffer. Useful for setting | |
| 400 options for a file type. Also executed when | |
| 401 starting to edit a buffer, after the | |
| 402 BufReadPost autocommands. | |
| 403 *BufFilePost* | |
| 404 BufFilePost After changing the name of the current buffer | |
| 405 with the ":file" or ":saveas" command. | |
| 625 | 406 *BufFilePre* |
| 579 | 407 BufFilePre Before changing the name of the current buffer |
| 408 with the ":file" or ":saveas" command. | |
| 409 *BufHidden* | |
| 410 BufHidden Just after a buffer has become hidden. That | |
| 411 is, when there are no longer windows that show | |
| 412 the buffer, but the buffer is not unloaded or | |
| 413 deleted. Not used for ":qa" or ":q" when | |
| 414 exiting Vim. | |
| 415 NOTE: When this autocommand is executed, the | |
| 416 current buffer "%" may be different from the | |
| 417 buffer being unloaded "<afile>". | |
| 418 *BufLeave* | |
| 419 BufLeave Before leaving to another buffer. Also when | |
| 420 leaving or closing the current window and the | |
| 421 new current window is not for the same buffer. | |
| 422 Not used for ":qa" or ":q" when exiting Vim. | |
| 423 *BufNew* | |
| 424 BufNew Just after creating a new buffer. Also used | |
| 425 just after a buffer has been renamed. When | |
| 426 the buffer is added to the buffer list BufAdd | |
| 427 will be triggered too. | |
| 428 NOTE: When this autocommand is executed, the | |
| 429 current buffer "%" may be different from the | |
| 430 buffer being created "<afile>". | |
| 7 | 431 *BufNewFile* |
| 432 BufNewFile When starting to edit a file that doesn't | |
| 433 exist. Can be used to read in a skeleton | |
| 434 file. | |
| 435 *BufRead* *BufReadPost* | |
| 436 BufRead or BufReadPost When starting to edit a new buffer, after | |
| 437 reading the file into the buffer, before | |
| 438 executing the modelines. See |BufWinEnter| | |
| 439 for when you need to do something after | |
| 440 processing the modelines. | |
| 441 This does NOT work for ":r file". Not used | |
| 442 when the file doesn't exist. Also used after | |
| 443 successfully recovering a file. | |
| 3682 | 444 Also triggered for the filetypedetect group |
| 445 when executing ":filetype detect" and when | |
| 446 writing an unnamed buffer in a way that the | |
| 447 buffer gets a name. | |
| 625 | 448 *BufReadCmd* |
| 7 | 449 BufReadCmd Before starting to edit a new buffer. Should |
| 450 read the file into the buffer. |Cmd-event| | |
| 625 | 451 *BufReadPre* *E200* *E201* |
| 579 | 452 BufReadPre When starting to edit a new buffer, before |
| 453 reading the file into the buffer. Not used | |
| 454 if the file doesn't exist. | |
| 455 *BufUnload* | |
| 456 BufUnload Before unloading a buffer. This is when the | |
| 457 text in the buffer is going to be freed. This | |
| 458 may be after a BufWritePost and before a | |
| 459 BufDelete. Also used for all buffers that are | |
| 460 loaded when Vim is going to exit. | |
| 461 NOTE: When this autocommand is executed, the | |
| 462 current buffer "%" may be different from the | |
| 463 buffer being unloaded "<afile>". | |

467 event is not triggered. |
| 579 | 468 *BufWinEnter* |
| 469 BufWinEnter After a buffer is displayed in a window. This | |
| 470 can be when the buffer is loaded (after | |
| 1621 | 471 processing the modelines) or when a hidden |
| 579 | 472 buffer is displayed in a window (and is no |
| 1621 | 473 longer hidden). |
| 474 Does not happen for |:split| without | |
| 475 arguments, since you keep editing the same | |
| 476 buffer, or ":split" with a file that's already | |
| 1668 | 477 open in a window, because it re-uses an |
| 478 existing buffer. But it does happen for a | |
| 479 ":split" with the name of the current buffer, | |
| 480 since it reloads that buffer. | |

| 486 Not when it's still visible in another window. | |
| 487 Also triggered when exiting. It's triggered | |
| 488 before BufUnload or BufHidden. | |

493 event is not triggered. |
| 579 | 494 *BufWipeout* |
| 495 BufWipeout Before completely deleting a buffer. The | |
| 496 BufUnload and BufDelete events may be called | |
| 497 first (if the buffer was loaded and was in the | |
| 498 buffer list). Also used just before a buffer | |
| 499 is renamed (also when it's not in the buffer | |
| 500 list). | |
| 501 NOTE: When this autocommand is executed, the | |
| 502 current buffer "%" may be different from the | |
| 503 buffer being deleted "<afile>". | |
| 1919 | 504 Don't change to another buffer, it will cause |
| 505 problems. | |
| 7 | 506 *BufWrite* *BufWritePre* |
| 507 BufWrite or BufWritePre Before writing the whole buffer to a file. | |
| 508 *BufWriteCmd* | |
| 509 BufWriteCmd Before writing the whole buffer to a file. | |
| 510 Should do the writing of the file and reset | |
| 39 | 511 'modified' if successful, unless '+' is in |
| 512 'cpo' and writing to another file |cpo-+|. | |
| 513 The buffer contents should not be changed. | |
| 3082 | 514 When the command resets 'modified' the undo |
| 515 information is adjusted to mark older undo | |
| 516 states as 'modified', like |:write| does. | |
| 39 | 517 |Cmd-event| |
| 579 | 518 *BufWritePost* |
| 519 BufWritePost After writing the whole buffer to a file | |
| 520 (should undo the commands for BufWritePre). | |
| 6154 | 521 *CmdUndefined* |
| 522 CmdUndefined When a user command is used but it isn't | |
| 523 defined. Useful for defining a command only | |
| 524 when it's used. The pattern is matched | |
| 525 against the command name. Both <amatch> and | |
| 526 <afile> are set to the name of the command. | |
| 527 NOTE: Autocompletion won't work until the | |
| 528 command is defined. An alternative is to | |
| 529 always define the user command and have it | |
| 530 invoke an autoloaded function. See |autoload|. | |

597 It is not allowed to change the text |textlock|. |
| 3682 | 598 *CompleteDone* |
| 599 CompleteDone After Insert mode completion is done. Either | |
| 600 when something was completed or abandoning | |
| 601 completion. |ins-completion| | |
| 6909 | 602 The |v:completed_item| variable contains |
| 603 information about the completed item. | |
| 3682 | 604 |
| 579 | 605 *CursorHold* |
| 606 CursorHold When the user doesn't press a key for the time | |
| 607 specified with 'updatetime'. Not re-triggered | |
| 608 until the user has pressed a key (i.e. doesn't | |
| 609 fire every 'updatetime' ms if you leave Vim to | |
| 610 make some coffee. :) See |CursorHold-example| | |
| 611 for previewing tags. | |
| 612 This event is only triggered in Normal mode. | |
| 1154 | 613 It is not triggered when waiting for a command |
| 614 argument to be typed, or a movement after an | |
| 615 operator. | |
| 610 | 616 While recording the CursorHold event is not |
| 617 triggered. |q| | |
| 6259 | 618 *<CursorHold>* |
| 619 Internally the autocommand is triggered by the | |
| 620 <CursorHold> key. In an expression mapping | |
| 621 |getchar()| may see this character. | |
| 622 | |
| 579 | 623 Note: Interactive commands cannot be used for |
| 624 this event. There is no hit-enter prompt, | |
| 625 the screen is updated directly (when needed). | |
| 626 Note: In the future there will probably be | |
| 627 another option to set the time. | |
| 628 Hint: to force an update of the status lines | |
| 629 use: > | |
| 630 :let &ro = &ro | |
| 631 < {only on Amiga, Unix, Win32, MSDOS and all GUI | |
| 632 versions} | |
| 661 | 633 *CursorHoldI* |
| 634 CursorHoldI Just like CursorHold, but in Insert mode. | |

| 4911 | 640 CursorMoved After the cursor was moved in Normal or Visual |
| 641 mode. Also when the text of the cursor line | |
| 642 has been changed, e.g., with "x", "rx" or "p". | |
| 661 | 643 Not triggered when there is typeahead or when |
| 644 an operator is pending. | |
| 667 | 645 For an example see |match-parens|. |
| 16023 | 646 Note: This can not be skipped with |
| 647 `:noautocmd`. | |
| 4264 | 648 Careful: This is triggered very often, don't |
| 649 do anything that the user does not expect or | |
| 650 that is slow. | |

| 666 marks for the range of lines. | |
| 667 *FileChangedRO* | |
| 668 FileChangedRO Before making the first change to a read-only | |
| 669 file. Can be used to check-out the file from | |
| 670 a source control system. Not triggered when | |
| 671 the change was caused by an autocommand. | |
| 672 This event is triggered when making the first | |
| 673 change in a buffer or the first change after | |
| 823 | 674 'readonly' was set, just before the change is |
| 675 applied to the text. | |
| 579 | 676 WARNING: If the autocommand moves the cursor |
| 677 the effect of the change is undefined. | |
| 819 | 678 *E788* |
| 679 It is not allowed to change to another buffer | |
| 680 here. You can reload the buffer but not edit | |
| 681 another one. | |

| 707 isn't automatically saved, use |VimLeavePre| | |
| 708 for really exiting. | |
| 7 | 709 *FileChangedShell* |
| 710 FileChangedShell When Vim notices that the modification time of | |
| 711 a file has changed since editing started. | |
| 712 Also when the file attributes of the file | |
| 5908 | 713 change or when the size of the file changes. |
| 714 |timestamp| | |
| 7 | 715 Mostly triggered after executing a shell |
| 716 command, but also with a |:checktime| command | |
| 11473 | 717 or when gvim regains input focus. |
| 7 | 718 This autocommand is triggered for each changed |
| 719 file. It is not used when 'autoread' is set | |
| 720 and the buffer was not changed. If a | |
| 721 FileChangedShell autocommand is present the | |
| 722 warning message and prompt is not given. | |
| 179 | 723 The |v:fcs_reason| variable is set to indicate |
| 724 what happened and |v:fcs_choice| can be used | |
| 725 to tell Vim what to do next. | |
| 7 | 726 NOTE: When this autocommand is executed, the |
| 727 current buffer "%" may be different from the | |
| 11347 | 728 buffer that was changed, which is in "<afile>". |
| 7 | 729 NOTE: The commands must not change the current |
| 730 buffer, jump to another buffer or delete a | |

| 733 endless loop. This means that while executing | |
| 734 commands for the FileChangedShell event no | |
| 735 other FileChangedShell event will be | |
| 736 triggered. | |
| 766 | 737 *FileChangedShellPost* |
| 738 FileChangedShellPost After handling a file that was changed outside | |
| 739 of Vim. Can be used to update the statusline. | |
| 579 | 740 *FileEncoding* |
| 741 FileEncoding Obsolete. It still works and is equivalent | |
| 742 to |EncodingChanged|. | |
| 743 *FileReadCmd* | |
| 744 FileReadCmd Before reading a file with a ":read" command. | |
| 745 Should do the reading of the file. |Cmd-event| | |
| 746 *FileReadPost* | |
| 747 FileReadPost After reading a file with a ":read" command. | |

| 750 used to operate on the lines just read. | |

| 761 *FileWriteCmd* | |
| 762 FileWriteCmd Before writing to a file, when not writing the | |
| 763 whole buffer. Should do the writing to the | |
| 764 file. Should not change the buffer. Use the | |
| 765 '[ and '] marks for the range of lines. | |
| 766 |Cmd-event| | |

| 771 FileWritePre Before writing to a file, when not writing the | |
| 772 whole buffer. Use the '[ and '] marks for the | |
| 773 range of lines. | |
| 774 *FilterReadPost* | |
| 775 FilterReadPost After reading a file from a filter command. | |
| 776 Vim checks the pattern against the name of | |
| 777 the current buffer as with FilterReadPre. | |
| 778 Not triggered when 'shelltemp' is off. | |
| 779 *FilterReadPre* *E135* | |
| 780 FilterReadPre Before reading a file from a filter command. | |
| 781 Vim checks the pattern against the name of | |
| 782 the current buffer, not the name of the | |
| 783 temporary file that is the output of the | |
| 784 filter command. | |
| 785 Not triggered when 'shelltemp' is off. | |
| 786 *FilterWritePost* | |
| 787 FilterWritePost After writing a file for a filter command or | |
| 15334 | 788 making a diff with an external diff (see |
| 789 DiffUpdated for internal diff). | |
| 579 | 790 Vim checks the pattern against the name of |
| 791 the current buffer as with FilterWritePre. | |
| 792 Not triggered when 'shelltemp' is off. | |
| 793 *FilterWritePre* | |
| 794 FilterWritePre Before writing a file for a filter command or | |
| 15334 | 795 making a diff with an external diff. |
| 579 | 796 Vim checks the pattern against the name of |
| 797 the current buffer, not the name of the | |
| 798 temporary file that is the output of the | |
| 799 filter command. | |
| 800 Not triggered when 'shelltemp' is off. | |
| 7 | 801 *FocusGained* |
| 802 FocusGained When Vim got input focus. Only for the GUI | |
| 803 version and a few console versions where this | |
| 804 can be detected. | |
| 805 *FocusLost* | |
| 806 FocusLost When Vim lost input focus. Only for the GUI | |
| 807 version and a few console versions where this | |
| 11 | 808 can be detected. May also happen when a |
| 809 dialog pops up. | |
| 7 | 810 *FuncUndefined* |
| 811 FuncUndefined When a user function is used but it isn't | |
| 812 defined. Useful for defining a function only | |
| 1154 | 813 when it's used. The pattern is matched |
| 814 against the function name. Both <amatch> and | |
| 815 <afile> are set to the name of the function. | |
| 6154 | 816 NOTE: When writing Vim scripts a better |
| 817 alternative is to use an autoloaded function. | |
| 161 | 818 See |autoload-functions|. |
| 579 | 819 *GUIEnter* |
| 820 GUIEnter After starting the GUI successfully, and after | |
| 821 opening the window. It is triggered before | |
| 822 VimEnter when using gvim. Can be used to | |
| 823 position the window from a .gvimrc file: > | |
| 824 :autocmd GUIEnter * winpos 100 50 | |
| 1154 | 825 < *GUIFailed* |
| 826 GUIFailed After starting the GUI failed. Vim may | |
| 827 continue to run in the terminal, if possible | |
| 828 (only on Unix and alikes, when connecting the | |
| 829 X server fails). You may want to quit Vim: > | |
| 830 :autocmd GUIFailed * qall | |
| 579 | 831 < *InsertChange* |
| 832 InsertChange When typing <Insert> while in Insert or | |
| 833 Replace mode. The |v:insertmode| variable | |
| 834 indicates the new mode. | |
| 835 Be careful not to move the cursor or do | |
| 836 anything else that the user does not expect. | |
| 2845 | 837 *InsertCharPre* |
| 838 InsertCharPre When a character is typed in Insert mode, | |
| 839 before inserting the char. | |
| 840 The |v:char| variable indicates the char typed | |
| 841 and can be changed during the event to insert | |
| 842 a different character. When |v:char| is set | |
| 843 to more than one character this text is | |
| 844 inserted literally. | |
| 845 It is not allowed to change the text |textlock|. | |
| 846 The event is not triggered when 'paste' is | |
| 13437 | 847 set. {only with the +eval feature} |
| 579 | 848 *InsertEnter* |
| 1154 | 849 InsertEnter Just before starting Insert mode. Also for |
| 850 Replace mode and Virtual Replace mode. The | |
| 579 | 851 |v:insertmode| variable indicates the mode. |
| 4448 | 852 Be careful not to do anything else that the |
| 853 user does not expect. | |
| 854 The cursor is restored afterwards. If you do | |
| 855 not want that set |v:char| to a non-empty | |
| 856 string. | |
| 579 | 857 *InsertLeave* |
| 858 InsertLeave When leaving Insert mode. Also when using | |
| 859 CTRL-O |i_CTRL-O|. But not for |i_CTRL-C|. | |
| 860 *MenuPopup* | |
| 861 MenuPopup Just before showing the popup menu (under the | |
| 862 right mouse button). Useful for adjusting the | |
| 863 menu for what is under the cursor or mouse | |
| 864 pointer. | |

| 993 StdinReadPre Before reading from stdin into the buffer. | |
| 994 Only used when the "-" argument was used when | |
| 995 Vim was started |--|. | |
| 996 *SwapExists* | |
| 997 SwapExists Detected an existing swap file when starting | |
| 998 to edit a file. Only when it is possible to | |
| 999 select a way to handle the situation, when Vim | |
| 1000 would ask the user what to do. | |
| 1001 The |v:swapname| variable holds the name of | |
| 590 | 1002 the swap file found, <afile> the file being |
| 1003 edited. |v:swapcommand| may contain a command | |
| 1004 to be executed in the opened file. | |
| 1005 The commands should set the |v:swapchoice| | |
| 1006 variable to a string with one character to | |
| 1007 tell Vim what should be done next: | |
| 579 | 1008 'o' open read-only |
| 1009 'e' edit the file anyway | |
| 1010 'r' recover | |
| 1011 'd' delete the swap file | |
| 1012 'q' quit, don't edit the file | |
| 1013 'a' abort, like hitting CTRL-C | |
| 1014 When set to an empty string the user will be | |
| 1015 asked, as if there was no SwapExists autocmd. | |
| 1919 | 1016 *E812* |
| 1017 It is not allowed to change to another buffer, | |
| 1018 change a buffer name or change directory | |
| 1019 here. | |
| 13437 | 1020 {only available with the +eval feature} |
| 579 | 1021 *Syntax* |
| 1154 | 1022 Syntax When the 'syntax' option has been set. The |
| 1023 pattern is matched against the syntax name. | |
| 579 | 1024 <afile> can be used for the name of the file |
| 1025 where this option was set, and <amatch> for | |
| 1026 the new value of 'syntax'. | |
| 1027 See |:syn-on|. | |

| 1152 If the window is for another buffer, Vim | |

| 1172 6. Patterns *autocmd-patterns* *{pat}* | |
| 1173 | |
| 6741 | 1174 The {pat} argument can be a comma separated list. This works as if the |
| 1175 command was given with each pattern separately. Thus this command: > | |
| 1176 :autocmd BufRead *.txt,*.info set et | |
| 1177 Is equivalent to: > | |
| 1178 :autocmd BufRead *.txt set et | |
| 1179 :autocmd BufRead *.info set et | |
| 1180 | |
| 7 | 1181 The file pattern {pat} is tested for a match against the file name in one of |
| 1182 two ways: | |
| 1183 1. When there is no '/' in the pattern, Vim checks for a match against only | |
| 1184 the tail part of the file name (without its leading directory path). | |

1187 it to a full path and resolving symbolic links). |
| 7 | 1188 |
| 40 | 1189 The special pattern <buffer> or <buffer=N> is used for buffer-local |
| 1190 autocommands |autocmd-buflocal|. This pattern is not matched against the name | |
| 1191 of a buffer. | |
| 1192 | |
| 7 | 1193 Examples: > |
| 1194 :autocmd BufRead *.txt set et | |
| 1195 Set the 'et' option for all text files. > | |
| 1196 | |
| 1197 :autocmd BufRead /vim/src/*.c set cindent | |
| 1198 Set the 'cindent' option for C files in the /vim/src directory. > | |
| 1199 | |
| 1200 :autocmd BufRead /tmp/*.c set ts=5 | |
| 1201 If you have a link from "/tmp/test.c" to "/home/nobody/vim/src/test.c", and | |
| 1202 you start editing "/tmp/test.c", this autocommand will match. | |
| 1203 | |
| 1204 Note: To match part of a path, but not from the root directory, use a '*' as | |
| 1205 the first character. Example: > | |
| 1206 :autocmd BufRead */doc/*.txt set tw=78 | |
| 1207 This autocommand will for example be executed for "/tmp/doc/xx.txt" and | |
| 1208 "/usr/home/piet/doc/yy.txt". The number of directories does not matter here. | |
| 1209 | |
| 1210 | |
| 1211 The file name that the pattern is matched against is after expanding | |
| 1621 | 1212 wildcards. Thus if you issue this command: > |
| 7 | 1213 :e $ROOTDIR/main.$EXT |
| 1214 The argument is first expanded to: > | |
| 1215 /usr/root/main.py | |
| 1216 Before it's matched with the pattern of the autocommand. Careful with this | |
| 1217 when using events like FileReadCmd, the value of <amatch> may not be what you | |
| 1218 expect. | |
| 1219 | |
| 1220 | |
| 1221 Environment variables can be used in a pattern: > | |
| 1222 :autocmd BufRead $VIMRUNTIME/doc/*.txt set expandtab | |
| 1223 And ~ can be used for the home directory (if $HOME is defined): > | |
| 1224 :autocmd BufWritePost ~/.vimrc so ~/.vimrc | |
| 1225 :autocmd BufRead ~archive/* set readonly | |
| 1226 The environment variable is expanded when the autocommand is defined, not when | |
| 1227 the autocommand is executed. This is different from the command! | |
| 1228 | |
| 1229 *file-pattern* | |
| 1230 The pattern is interpreted like mostly used in file names: | |
| 5294 | 1231 * matches any sequence of characters; Unusual: includes path |
| 5277 | 1232 separators |
| 7 | 1233 ? matches any single character |
| 1234 \? matches a '?' | |
| 1235 . matches a '.' | |
| 1236 ~ matches a '~' | |
| 1237 , separates patterns | |
| 1238 \, matches a ',' | |
| 1239 { } like \( \) in a |pattern| | |
| 1240 , inside { }: like \| in a |pattern| | |

| 1250 in a pattern and to make the autocommands portable across different systems. | |

| 40 | 1255 *autocmd-changes* |
| 7 | 1256 Matching with the pattern is done when an event is triggered. Changing the |
| 1257 buffer name in one of the autocommands, or even deleting the buffer, does not | |
| 1258 change which autocommands will be executed. Example: > | |
| 1259 | |
| 1260 au BufEnter *.foo bdel | |
| 1261 au BufEnter *.foo set modified | |
| 1262 | |
| 1263 This will delete the current buffer and then set 'modified' in what has become | |
| 1264 the current buffer instead. Vim doesn't take into account that "*.foo" | |
| 1265 doesn't match with that buffer name. It matches "*.foo" with the name of the | |
| 1266 buffer at the moment the event was triggered. | |
| 1267 | |
| 40 | 1268 However, buffer-local autocommands will not be executed for a buffer that has |
| 1269 been wiped out with |:bwipe|. After deleting the buffer with |:bdel| the | |
| 1270 buffer actually still exists (it becomes unlisted), thus the autocommands are | |
| 1271 still executed. | |
| 1272 | |
| 7 | 1273 ============================================================================== |
| 856 | 1274 7. Buffer-local autocommands *autocmd-buflocal* *autocmd-buffer-local* |
| 1275 *<buffer=N>* *<buffer=abuf>* *E680* | |
| 40 | 1276 |
| 1277 Buffer-local autocommands are attached to a specific buffer. They are useful | |
| 1278 if the buffer does not have a name and when the name does not match a specific | |
| 1279 pattern. But it also means they must be explicitly added to each buffer. | |
| 1280 | |
| 1281 Instead of a pattern buffer-local autocommands use one of these forms: | |
| 1282 <buffer> current buffer | |
| 1283 <buffer=99> buffer number 99 | |
| 1284 <buffer=abuf> using <abuf> (only when executing autocommands) | |
| 1285 |<abuf>| | |
| 1286 | |
| 1287 Examples: > | |
| 1288 :au CursorHold <buffer> echo 'hold' | |
| 1289 :au CursorHold <buffer=33> echo 'hold' | |

1290 :au BufNewFile * au CursorHold <buffer=abuf> echo 'hold' |
| 40 | 1291 |
| 1292 All the commands for autocommands also work with buffer-local autocommands, | |
| 1293 simply use the special string instead of the pattern. Examples: > | |
| 856 | 1294 :au! * <buffer> " remove buffer-local autocommands for |
| 1295 " current buffer | |
| 1296 :au! * <buffer=33> " remove buffer-local autocommands for | |
| 1297 " buffer #33 | |
| 1621 | 1298 :bufdo :au! CursorHold <buffer> " remove autocmd for given event for all |
| 856 | 1299 " buffers |
| 1300 :au * <buffer> " list buffer-local autocommands for | |
| 1301 " current buffer | |
| 40 | 1302 |
| 1303 Note that when an autocommand is defined for the current buffer, it is stored | |
| 1304 with the buffer number. Thus it uses the form "<buffer=12>", where 12 is the | |
| 1305 number of the current buffer. You will see this when listing autocommands, | |
| 1306 for example. | |
| 1307 | |
| 1308 To test for presence of buffer-local autocommands use the |exists()| function | |
| 1309 as follows: > | |
| 1310 :if exists("#CursorHold#<buffer=12>") | ... | endif | |
| 1311 :if exists("#CursorHold#<buffer>") | ... | endif " for current buffer | |
| 1312 | |
| 1313 When a buffer is wiped out its buffer-local autocommands are also gone, of | |
| 1314 course. Note that when deleting a buffer, e.g., with ":bdel", it is only | |
| 1315 unlisted, the autocommands are still present. In order to see the removal of | |
| 1316 buffer-local autocommands: > | |
| 1317 :set verbose=6 | |
| 1318 | |
| 1319 It is not possible to define buffer-local autocommands for a non-existent | |
| 1320 buffer. | |
| 1321 | |
| 1322 ============================================================================== | |
| 1323 8. Groups *autocmd-groups* | |
| 7 | 1324 |
| 1325 Autocommands can be put together in a group. This is useful for removing or | |
| 1326 executing a group of autocommands. For example, all the autocommands for | |
| 1327 syntax highlighting are put in the "highlight" group, to be able to execute | |
| 1328 ":doautoall highlight BufRead" when the GUI starts. | |
| 1329 | |
| 1330 When no specific group is selected, Vim uses the default group. The default | |
| 1331 group does not have a name. You cannot execute the autocommands from the | |
| 1332 default group separately; you can execute them only by executing autocommands | |
| 1333 for all groups. | |
| 1334 | |
| 1335 Normally, when executing autocommands automatically, Vim uses the autocommands | |
| 1336 for all groups. The group only matters when executing autocommands with | |
| 1337 ":doautocmd" or ":doautoall", or when defining or deleting autocommands. | |
| 1338 | |
| 1339 The group name can contain any characters except white space. The group name | |
| 1340 "end" is reserved (also in uppercase). | |
| 1341 | |
| 1342 The group name is case sensitive. Note that this is different from the event | |
| 1343 name! | |
| 1344 | |
| 1345 *:aug* *:augroup* | |
| 1346 :aug[roup] {name} Define the autocmd group name for the | |
| 1347 following ":autocmd" commands. The name "end" | |
| 1348 or "END" selects the default group. | |

1358 you will get error E936. |
| 7 | 1359 |
| 1360 To enter autocommands for a specific group, use this method: | |
| 1361 1. Select the group with ":augroup {name}". | |
| 1362 2. Delete any old autocommands with ":au!". | |
| 1363 3. Define the autocommands. | |
| 1364 4. Go back to the default group with "augroup END". | |
| 1365 | |
| 1366 Example: > | |
| 1367 :augroup uncompress | |
| 1368 : au! | |
| 1369 : au BufEnter *.gz %!gunzip | |
| 1370 :augroup END | |
| 1371 | |
| 1372 This prevents having the autocommands defined twice (e.g., after sourcing the | |
| 1373 .vimrc file again). | |
| 1374 | |
| 1375 ============================================================================== | |
| 40 | 1376 9. Executing autocommands *autocmd-execute* |
| 7 | 1377 |
| 1378 Vim can also execute Autocommands non-automatically. This is useful if you | |
| 1379 have changed autocommands, or when Vim has executed the wrong autocommands | |
| 1380 (e.g., the file pattern match was wrong). | |
| 1381 | |
| 1382 Note that the 'eventignore' option applies here too. Events listed in this | |
| 1383 option will not cause any commands to be executed. | |
| 1384 | |
| 16944 | 1385 *:do* *:doau* *:doaut* *:doautocmd* *E217* |
| 3356 | 1386 :do[autocmd] [<nomodeline>] [group] {event} [fname] |
| 7 | 1387 Apply the autocommands matching [fname] (default: |
| 1388 current file name) for {event} to the current buffer. | |
| 1389 You can use this when the current file name does not | |
| 1390 match the right pattern, after changing settings, or | |
| 1391 to execute autocommands for a certain event. | |
| 1392 It's possible to use this inside an autocommand too, | |
| 1393 so you can base the autocommands for one extension on | |
| 1394 another extension. Example: > | |
| 3224 | 1395 :au BufEnter *.cpp so ~/.vimrc_cpp |
| 1396 :au BufEnter *.cpp doau BufEnter x.c | |
| 7 | 1397 < Be careful to avoid endless loops. See |
| 1398 |autocmd-nested|. | |
| 1399 | |
| 1400 When the [group] argument is not given, Vim executes | |
| 1401 the autocommands for all groups. When the [group] | |
| 1402 argument is included, Vim executes only the matching | |
| 1403 autocommands for that group. Note: if you use an | |
| 1404 undefined group name, Vim gives you an error message. | |
| 3350 | 1405 *<nomodeline>* |
| 1406 After applying the autocommands the modelines are | |
| 1407 processed, so that their settings overrule the | |
| 1408 settings from autocommands, like what happens when | |
| 1409 editing a file. This is skipped when the <nomodeline> | |
| 1410 argument is present. You probably want to use | |
| 1411 <nomodeline> for events that are not used when loading | |
| 1412 a buffer, such as |User|. | |

1419 loaded buffer. Note that [fname] is used to select |
| 7 | 1420 the autocommands, not the buffers to which they are |
| 1421 applied. | |
| 1422 Careful: Don't use this for autocommands that delete a | |
| 1423 buffer, change to another buffer or change the | |
| 1424 contents of a buffer; the result is unpredictable. | |
| 1425 This command is intended for autocommands that set | |
| 1426 options, change highlighting, and things like that. | |
| 1427 | |
| 1428 ============================================================================== | |
| 40 | 1429 10. Using autocommands *autocmd-use* |
| 7 | 1430 |
| 1431 For WRITING FILES there are four possible sets of events. Vim uses only one | |
| 1432 of these sets for a write command: | |
| 1433 | |
| 1434 BufWriteCmd BufWritePre BufWritePost writing the whole buffer | |
| 1435 FilterWritePre FilterWritePost writing to filter temp file | |
| 1436 FileAppendCmd FileAppendPre FileAppendPost appending to a file | |
| 1437 FileWriteCmd FileWritePre FileWritePost any other file write | |
| 1438 | |
| 1439 When there is a matching "*Cmd" autocommand, it is assumed it will do the | |
| 1440 writing. No further writing is done and the other events are not triggered. | |
| 1441 |Cmd-event| | |
| 1442 | |
| 1443 Note that the *WritePost commands should undo any changes to the buffer that | |
| 1444 were caused by the *WritePre commands; otherwise, writing the file will have | |
| 1445 the side effect of changing the buffer. | |
| 1446 | |
| 1447 Before executing the autocommands, the buffer from which the lines are to be | |
| 1448 written temporarily becomes the current buffer. Unless the autocommands | |
| 1449 change the current buffer or delete the previously current buffer, the | |
| 1450 previously current buffer is made the current buffer again. | |
| 1451 | |
| 1452 The *WritePre and *AppendPre autocommands must not delete the buffer from | |
| 1453 which the lines are to be written. | |
| 1454 | |
| 1455 The '[ and '] marks have a special position: | |
| 1456 - Before the *ReadPre event the '[ mark is set to the line just above where | |
| 1457 the new lines will be inserted. | |
| 1458 - Before the *ReadPost event the '[ mark is set to the first line that was | |
| 1459 just read, the '] mark to the last line. | |
| 26 | 1460 - Before executing the *WriteCmd, *WritePre and *AppendPre autocommands the '[ |
| 1461 mark is set to the first line that will be written, the '] mark to the last | |
| 1462 line. | |
| 7 | 1463 Careful: '[ and '] change when using commands that change the buffer. |
| 1464 | |
| 1465 In commands which expect a file name, you can use "<afile>" for the file name | |
| 1466 that is being read |:<afile>| (you can also use "%" for the current file | |
| 1467 name). "<abuf>" can be used for the buffer number of the currently effective | |
| 14123 | 1468 buffer. This also works for buffers that don't have a name. But it doesn't |
| 7 | 1469 work for files without a buffer (e.g., with ":r file"). |
| 1470 | |
| 1471 *gzip-example* | |
| 1472 Examples for reading and writing compressed files: > | |
| 1473 :augroup gzip | |
| 1474 : autocmd! | |
| 1475 : autocmd BufReadPre,FileReadPre *.gz set bin | |
| 1476 : autocmd BufReadPost,FileReadPost *.gz '[,']!gunzip | |
| 1477 : autocmd BufReadPost,FileReadPost *.gz set nobin | |
| 1478 : autocmd BufReadPost,FileReadPost *.gz execute ":doautocmd BufReadPost " . expand("%:r") | |
| 1479 : autocmd BufWritePost,FileWritePost *.gz !mv <afile> <afile>:r | |
| 1480 : autocmd BufWritePost,FileWritePost *.gz !gzip <afile>:r | |
| 1481 | |
| 1482 : autocmd FileAppendPre *.gz !gunzip <afile> | |
| 1483 : autocmd FileAppendPre *.gz !mv <afile>:r <afile> | |
| 1484 : autocmd FileAppendPost *.gz !mv <afile> <afile>:r | |
| 1485 : autocmd FileAppendPost *.gz !gzip <afile>:r | |
| 1486 :augroup END | |
| 1487 | |
| 1488 The "gzip" group is used to be able to delete any existing autocommands with | |
| 1489 ":autocmd!", for when the file is sourced twice. | |
| 1490 | |
| 1491 ("<afile>:r" is the file name without the extension, see |:_%:|) | |
| 1492 | |
| 1493 The commands executed for the BufNewFile, BufRead/BufReadPost, BufWritePost, | |
| 1494 FileAppendPost and VimLeave events do not set or reset the changed flag of the | |
| 1495 buffer. When you decompress the buffer with the BufReadPost autocommands, you | |
| 1496 can still exit with ":q". When you use ":undo" in BufWritePost to undo the | |
| 1497 changes made by BufWritePre commands, you can still do ":q" (this also makes | |
| 1498 "ZZ" work). If you do want the buffer to be marked as modified, set the | |
| 1499 'modified' option. | |
| 1500 | |
| 1501 To execute Normal mode commands from an autocommand, use the ":normal" | |
| 1502 command. Use with care! If the Normal mode command is not finished, the user | |
| 1503 needs to type characters (e.g., after ":normal m" you need to type a mark | |
| 1504 name). | |
| 1505 | |
| 1506 If you want the buffer to be unmodified after changing it, reset the | |
| 1507 'modified' option. This makes it possible to exit the buffer with ":q" | |
| 1508 instead of ":q!". | |
| 1509 | |
| 1510 *autocmd-nested* *E218* | |
| 16023 | 1511 By default, autocommands do not nest. For example, if you use ":e" or ":w" in |
| 1512 an autocommand, Vim does not execute the BufRead and BufWrite autocommands for | |
| 7 | 1513 those commands. If you do want this, use the "nested" flag for those commands |
| 1514 in which you want nesting. For example: > | |

1515 :autocmd FileChangedShell *.c ++nested e! |
| 7 | 1516 The nesting is limited to 10 levels to get out of recursive loops. |
| 1517 | |
| 1518 It's possible to use the ":au" command in an autocommand. This can be a | |
| 1519 self-modifying command! This can be useful for an autocommand that should | |
| 1520 execute only once. | |
| 1521 | |
| 590 | 1522 If you want to skip autocommands for one command, use the |:noautocmd| command |
| 1523 modifier or the 'eventignore' option. | |
| 7 | 1524 |
| 1525 Note: When reading a file (with ":read file" or with a filter command) and the | |
| 1526 last line in the file does not have an <EOL>, Vim remembers this. At the next | |
| 1527 write (with ":write file" or with a filter command), if the same line is | |
| 1528 written again as the last line in a file AND 'binary' is set, Vim does not | |
| 1529 supply an <EOL>. This makes a filter command on the just read lines write the | |
| 1530 same file as was read, and makes a write command on just filtered lines write | |
| 1531 the same file as was read from the filter. For example, another way to write | |
| 1532 a compressed file: > | |
| 1533 | |
| 1534 :autocmd FileWritePre *.gz set bin|'[,']!gzip | |
| 1535 :autocmd FileWritePost *.gz undo|set nobin | |
| 1536 < | |
| 1537 *autocommand-pattern* | |
| 1538 You can specify multiple patterns, separated by commas. Here are some | |
| 1539 examples: > | |
| 1540 | |
| 1541 :autocmd BufRead * set tw=79 nocin ic infercase fo=2croq | |
| 1542 :autocmd BufRead .letter set tw=72 fo=2tcrq | |
| 1543 :autocmd BufEnter .letter set dict=/usr/lib/dict/words | |
| 1544 :autocmd BufLeave .letter set dict= | |
| 1545 :autocmd BufRead,BufNewFile *.c,*.h set tw=0 cin noic | |
| 1546 :autocmd BufEnter *.c,*.h abbr FOR for (i = 0; i < 3; ++i)<CR>{<CR>}<Esc>O | |
| 1547 :autocmd BufLeave *.c,*.h unabbr FOR | |
| 1548 | |
| 1549 For makefiles (makefile, Makefile, imakefile, makefile.unix, etc.): > | |
| 1550 | |
| 1551 :autocmd BufEnter ?akefile* set include=^s\=include | |
| 1552 :autocmd BufLeave ?akefile* set include& | |
| 1553 | |
| 1554 To always start editing C files at the first function: > | |
| 1555 | |
| 1556 :autocmd BufRead *.c,*.h 1;/^{ | |
| 1557 | |
| 1558 Without the "1;" above, the search would start from wherever the file was | |
| 1559 entered, rather than from the start of the file. | |
| 1560 | |
| 1561 *skeleton* *template* | |
| 1562 To read a skeleton (template) file when opening a new file: > | |
| 1563 | |
| 1564 :autocmd BufNewFile *.c 0r ~/vim/skeleton.c | |
| 1565 :autocmd BufNewFile *.h 0r ~/vim/skeleton.h | |
| 1566 :autocmd BufNewFile *.java 0r ~/vim/skeleton.java | |
| 1567 | |
| 1568 To insert the current date and time in a *.html file when writing it: > | |
| 1569 | |
| 1570 :autocmd BufWritePre,FileWritePre *.html ks|call LastMod()|'s | |
| 1571 :fun LastMod() | |
| 1572 : if line("$") > 20 | |
| 1573 : let l = 20 | |
| 1574 : else | |
| 1575 : let l = line("$") | |
| 1576 : endif | |
| 1577 : exe "1," . l . "g/Last modified: /s/Last modified: .*/Last modified: " . | |
| 1578 : \ strftime("%Y %b %d") | |
| 1579 :endfun | |
| 1580 | |
| 1581 You need to have a line "Last modified: <date time>" in the first 20 lines | |
| 1582 of the file for this to work. Vim replaces <date time> (and anything in the | |
| 1583 same line after it) with the current date and time. Explanation: | |
| 1584 ks mark current position with mark 's' | |
| 1585 call LastMod() call the LastMod() function to do the work | |
| 1586 's return the cursor to the old position | |
| 1587 The LastMod() function checks if the file is shorter than 20 lines, and then | |
| 1588 uses the ":g" command to find lines that contain "Last modified: ". For those | |
| 1589 lines the ":s" command is executed to replace the existing date with the | |
| 1590 current one. The ":execute" command is used to be able to use an expression | |
| 1591 for the ":g" and ":s" commands. The date is obtained with the strftime() | |
| 1592 function. You can change its argument to get another date string. | |
| 1593 | |
| 1594 When entering :autocmd on the command-line, completion of events and command | |
| 1595 names may be done (with <Tab>, CTRL-D, etc.) where appropriate. | |
| 1596 | |
| 1597 Vim executes all matching autocommands in the order that you specify them. | |
| 1598 It is recommended that your first autocommand be used for all files by using | |
| 1599 "*" as the file pattern. This means that you can define defaults you like | |
| 1600 here for any settings, and if there is another matching autocommand it will | |
| 1601 override these. But if there is no other matching autocommand, then at least | |
| 1602 your default settings are recovered (if entering this file from another for | |
| 1603 which autocommands did match). Note that "*" will also match files starting | |
| 1604 with ".", unlike Unix shells. | |
| 1605 | |
| 1606 *autocmd-searchpat* | |
| 1607 Autocommands do not change the current search patterns. Vim saves the current | |
| 1608 search patterns before executing autocommands then restores them after the | |
| 1609 autocommands finish. This means that autocommands do not affect the strings | |
| 1610 highlighted with the 'hlsearch' option. Within autocommands, you can still | |
| 1611 use search patterns normally, e.g., with the "n" command. | |
| 1612 If you want an autocommand to set the search pattern, such that it is used | |
| 1613 after the autocommand finishes, use the ":let @/ =" command. | |
| 1614 The search-highlighting cannot be switched off with ":nohlsearch" in an | |
| 1615 autocommand. Use the 'h' flag in the 'viminfo' option to disable search- | |
| 1616 highlighting when starting Vim. | |
| 1617 | |
| 1618 *Cmd-event* | |
| 1619 When using one of the "*Cmd" events, the matching autocommands are expected to | |
| 1061 | 1620 do the file reading, writing or sourcing. This can be used when working with |
| 1621 a special kind of file, for example on a remote system. | |
| 7 | 1622 CAREFUL: If you use these events in a wrong way, it may have the effect of |
| 1623 making it impossible to read or write the matching files! Make sure you test | |
| 1624 your autocommands properly. Best is to use a pattern that will never match a | |
| 1625 normal file name, for example "ftp://*". | |
| 1626 | |
| 1627 When defining a BufReadCmd it will be difficult for Vim to recover a crashed | |
| 1628 editing session. When recovering from the original file, Vim reads only those | |
| 1629 parts of a file that are not found in the swap file. Since that is not | |
| 1630 possible with a BufReadCmd, use the |:preserve| command to make sure the | |
| 1631 original file isn't needed for recovery. You might want to do this only when | |
| 1632 you expect the file to be modified. | |
| 1633 | |
| 1061 | 1634 For file read and write commands the |v:cmdarg| variable holds the "++enc=" |
| 1635 and "++ff=" argument that are effective. These should be used for the command | |
| 1636 that reads/writes the file. The |v:cmdbang| variable is one when "!" was | |
| 1637 used, zero otherwise. | |

| 1642 11. Disabling autocommands *autocmd-disable* | |
| 1643 | |
| 1644 To disable autocommands for some time use the 'eventignore' option. Note that | |
| 1645 this may cause unexpected behavior, make sure you restore 'eventignore' | |
| 1646 afterwards, using a |:try| block with |:finally|. | |
| 1647 | |
| 1648 *:noautocmd* *:noa* | |
| 1649 To disable autocommands for just one command use the ":noautocmd" command | |
| 1650 modifier. This will set 'eventignore' to "all" for the duration of the | |
| 1651 following command. Example: > | |
| 1652 | |
| 1653 :noautocmd w fname.gz | |
| 1654 | |
| 1655 This will write the file without triggering the autocommands defined by the | |
| 1656 gzip plugin. | |
| 1657 | |
| 16023 | 1658 Note that some autocommands are not triggered right away, but only later. |
| 1659 This specifically applies to |CursorMoved| and |TextChanged|. | |
