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

| 7 | 81 Note that special characters (e.g., "%", "<cword>") in the ":autocmd" |
| 82 arguments are not expanded when the autocommand is defined. These will be | |
| 83 expanded when the Event is recognized, and the {cmd} is executed. The only | |
| 84 exception is that "<sfile>" is expanded when the autocmd is defined. Example: | |
| 85 > | |
| 86 :au BufNewFile,BufRead *.html so <sfile>:h/html.vim | |
| 87 | |
| 88 Here Vim expands <sfile> to the name of the file containing this line. | |

99 augroup END |
| 7 | 100 |
| 101 If you don't want to remove all autocommands, you can instead use a variable | |
| 102 to ensure that Vim includes the autocommands only once: > | |
| 103 | |
| 104 :if !exists("autocommands_loaded") | |
| 105 : let autocommands_loaded = 1 | |
| 106 : au ... | |
| 107 :endif | |
| 108 | |
| 109 When the [group] argument is not given, Vim uses the current group (as defined | |
| 110 with ":augroup"); otherwise, Vim uses the group defined with [group]. Note | |
| 111 that [group] must have been defined before. You cannot define a new group | |
| 112 with ":au group ..."; use ":augroup" for that. | |
| 113 | |
| 114 While testing autocommands, you might find the 'verbose' option to be useful: > | |
| 115 :set verbose=9 | |
| 116 This setting makes Vim echo the autocommands as it executes them. | |
| 117 | |
| 118 When defining an autocommand in a script, it will be able to call functions | |
| 119 local to the script and use mappings local to the script. When the event is | |
| 120 triggered and the command executed, it will run in the context of the script | |
| 121 it was defined in. This matters if |<SID>| is used in a command. | |
| 122 | |
| 1621 | 123 When executing the commands, the message from one command overwrites a |
| 7 | 124 previous message. This is different from when executing the commands |
| 125 manually. Mostly the screen will not scroll up, thus there is no hit-enter | |
| 126 prompt. When one command outputs two messages this can happen anyway. | |
| 127 | |
| 128 ============================================================================== | |
| 129 3. Removing autocommands *autocmd-remove* | |
| 130 | |
| 131 :au[tocmd]! [group] {event} {pat} [nested] {cmd} | |
| 132 Remove all autocommands associated with {event} and | |
| 133 {pat}, and add the command {cmd}. See | |
| 134 |autocmd-nested| for [nested]. | |
| 135 | |
| 136 :au[tocmd]! [group] {event} {pat} | |
| 137 Remove all autocommands associated with {event} and | |
| 138 {pat}. | |
| 139 | |
| 140 :au[tocmd]! [group] * {pat} | |
| 141 Remove all autocommands associated with {pat} for all | |
| 142 events. | |
| 143 | |
| 144 :au[tocmd]! [group] {event} | |
| 145 Remove ALL autocommands for {event}. | |

154 group, it breaks plugins, syntax highlighting, etc. |
| 7 | 155 |
| 156 When the [group] argument is not given, Vim uses the current group (as defined | |
| 157 with ":augroup"); otherwise, Vim uses the group defined with [group]. | |
| 158 | |
| 159 ============================================================================== | |
| 160 4. Listing autocommands *autocmd-list* | |
| 161 | |
| 162 :au[tocmd] [group] {event} {pat} | |
| 163 Show the autocommands associated with {event} and | |
| 164 {pat}. | |
| 165 | |
| 166 :au[tocmd] [group] * {pat} | |
| 167 Show the autocommands associated with {pat} for all | |
| 168 events. | |
| 169 | |
| 170 :au[tocmd] [group] {event} | |
| 171 Show all autocommands for {event}. | |
| 172 | |
| 173 :au[tocmd] [group] Show all autocommands. | |
| 174 | |
| 175 If you provide the [group] argument, Vim lists only the autocommands for | |
| 176 [group]; otherwise, Vim lists the autocommands for ALL groups. Note that this | |
| 177 argument behavior differs from that for defining and removing autocommands. | |
| 178 | |
| 40 | 179 In order to list buffer-local autocommands, use a pattern in the form <buffer> |
| 180 or <buffer=N>. See |autocmd-buflocal|. | |
| 181 | |
| 500 | 182 *:autocmd-verbose* |
| 183 When 'verbose' is non-zero, listing an autocommand will also display where it | |
| 184 was last defined. Example: > | |
| 185 | |
| 186 :verbose autocmd BufEnter | |
| 187 FileExplorer BufEnter | |
| 856 | 188 * call s:LocalBrowse(expand("<amatch>")) |
| 500 | 189 Last set from /usr/share/vim/vim-7.0/plugin/NetrwPlugin.vim |
| 190 < | |
| 191 See |:verbose-cmd| for more information. | |
| 192 | |
| 7 | 193 ============================================================================== |
| 194 5. Events *autocmd-events* *E215* *E216* | |
| 195 | |
| 579 | 196 You can specify a comma-separated list of event names. No white space can be |
| 197 used in this list. The command applies to all the events in the list. | |
| 198 | |
| 199 For READING FILES there are four kinds of events possible: | |
| 200 BufNewFile starting to edit a non-existent file | |
| 201 BufReadPre BufReadPost starting to edit an existing file | |
| 202 FilterReadPre FilterReadPost read the temp file with filter output | |
| 203 FileReadPre FileReadPost any other file read | |
| 204 Vim uses only one of these four kinds when reading a file. The "Pre" and | |
| 205 "Post" events are both triggered, before and after reading the file. | |
| 206 | |
| 207 Note that the autocommands for the *ReadPre events and all the Filter events | |
| 208 are not allowed to change the current buffer (you will get an error message if | |
| 209 this happens). This is to prevent the file to be read into the wrong buffer. | |
| 210 | |
| 211 Note that the 'modified' flag is reset AFTER executing the BufReadPost | |
| 212 and BufNewFile autocommands. But when the 'modified' option was set by the | |
| 213 autocommands, this doesn't happen. | |
| 214 | |
| 215 You can use the 'eventignore' option to ignore a number of events or all | |
| 216 events. | |
| 7 | 217 *autocommand-events* *{event}* |
| 218 Vim recognizes the following events. Vim ignores the case of event names | |
| 219 (e.g., you can use "BUFread" or "bufread" instead of "BufRead"). | |
| 220 | |

| 367 | |
| 368 The alphabetical list of autocommand events: *autocmd-events-abc* | |
| 369 | |
| 370 *BufCreate* *BufAdd* | |
| 371 BufAdd or BufCreate Just after creating a new buffer which is | |
| 372 added to the buffer list, or adding a buffer | |
| 373 to the buffer list. | |
| 374 Also used just after a buffer in the buffer | |
| 375 list has been renamed. | |
| 376 The BufCreate event is for historic reasons. | |
| 377 NOTE: When this autocommand is executed, the | |
| 378 current buffer "%" may be different from the | |
| 379 buffer being created "<afile>". | |
| 380 *BufDelete* | |
| 381 BufDelete Before deleting a buffer from the buffer list. | |
| 382 The BufUnload may be called first (if the | |
| 383 buffer was loaded). | |
| 384 Also used just before a buffer in the buffer | |
| 385 list is renamed. | |
| 386 NOTE: When this autocommand is executed, the | |
| 387 current buffer "%" may be different from the | |
| 1621 | 388 buffer being deleted "<afile>" and "<abuf>". |
| 1919 | 389 Don't change to another buffer, it will cause |
| 390 problems. | |
| 579 | 391 *BufEnter* |
| 392 BufEnter After entering a buffer. Useful for setting | |
| 393 options for a file type. Also executed when | |
| 394 starting to edit a buffer, after the | |
| 395 BufReadPost autocommands. | |
| 396 *BufFilePost* | |
| 397 BufFilePost After changing the name of the current buffer | |
| 398 with the ":file" or ":saveas" command. | |
| 625 | 399 *BufFilePre* |
| 579 | 400 BufFilePre Before changing the name of the current buffer |
| 401 with the ":file" or ":saveas" command. | |
| 402 *BufHidden* | |
| 403 BufHidden Just after a buffer has become hidden. That | |
| 404 is, when there are no longer windows that show | |
| 405 the buffer, but the buffer is not unloaded or | |
| 406 deleted. Not used for ":qa" or ":q" when | |
| 407 exiting Vim. | |
| 408 NOTE: When this autocommand is executed, the | |
| 409 current buffer "%" may be different from the | |
| 410 buffer being unloaded "<afile>". | |
| 411 *BufLeave* | |
| 412 BufLeave Before leaving to another buffer. Also when | |
| 413 leaving or closing the current window and the | |
| 414 new current window is not for the same buffer. | |
| 415 Not used for ":qa" or ":q" when exiting Vim. | |
| 416 *BufNew* | |
| 417 BufNew Just after creating a new buffer. Also used | |
| 418 just after a buffer has been renamed. When | |
| 419 the buffer is added to the buffer list BufAdd | |
| 420 will be triggered too. | |
| 421 NOTE: When this autocommand is executed, the | |
| 422 current buffer "%" may be different from the | |
| 423 buffer being created "<afile>". | |
| 7 | 424 *BufNewFile* |
| 425 BufNewFile When starting to edit a file that doesn't | |
| 426 exist. Can be used to read in a skeleton | |
| 427 file. | |
| 428 *BufRead* *BufReadPost* | |
| 429 BufRead or BufReadPost When starting to edit a new buffer, after | |
| 430 reading the file into the buffer, before | |
| 431 executing the modelines. See |BufWinEnter| | |
| 432 for when you need to do something after | |
| 433 processing the modelines. | |
| 434 This does NOT work for ":r file". Not used | |
| 435 when the file doesn't exist. Also used after | |
| 436 successfully recovering a file. | |
| 3682 | 437 Also triggered for the filetypedetect group |
| 438 when executing ":filetype detect" and when | |
| 439 writing an unnamed buffer in a way that the | |
| 440 buffer gets a name. | |
| 625 | 441 *BufReadCmd* |
| 7 | 442 BufReadCmd Before starting to edit a new buffer. Should |
| 443 read the file into the buffer. |Cmd-event| | |
| 625 | 444 *BufReadPre* *E200* *E201* |
| 579 | 445 BufReadPre When starting to edit a new buffer, before |
| 446 reading the file into the buffer. Not used | |
| 447 if the file doesn't exist. | |
| 448 *BufUnload* | |
| 449 BufUnload Before unloading a buffer. This is when the | |
| 450 text in the buffer is going to be freed. This | |
| 451 may be after a BufWritePost and before a | |
| 452 BufDelete. Also used for all buffers that are | |
| 453 loaded when Vim is going to exit. | |
| 454 NOTE: When this autocommand is executed, the | |
| 455 current buffer "%" may be different from the | |
| 456 buffer being unloaded "<afile>". | |

460 event is not triggered. |
| 579 | 461 *BufWinEnter* |
| 462 BufWinEnter After a buffer is displayed in a window. This | |
| 463 can be when the buffer is loaded (after | |
| 1621 | 464 processing the modelines) or when a hidden |
| 579 | 465 buffer is displayed in a window (and is no |
| 1621 | 466 longer hidden). |
| 467 Does not happen for |:split| without | |
| 468 arguments, since you keep editing the same | |
| 469 buffer, or ":split" with a file that's already | |
| 1668 | 470 open in a window, because it re-uses an |
| 471 existing buffer. But it does happen for a | |
| 472 ":split" with the name of the current buffer, | |
| 473 since it reloads that buffer. | |

| 479 Not when it's still visible in another window. | |
| 480 Also triggered when exiting. It's triggered | |
| 481 before BufUnload or BufHidden. | |
| 482 NOTE: When this autocommand is executed, the | |

| 484 buffer being unloaded "<afile>". | |

486 event is not triggered. |
| 579 | 487 *BufWipeout* |
| 488 BufWipeout Before completely deleting a buffer. The | |
| 489 BufUnload and BufDelete events may be called | |
| 490 first (if the buffer was loaded and was in the | |
| 491 buffer list). Also used just before a buffer | |
| 492 is renamed (also when it's not in the buffer | |
| 493 list). | |
| 494 NOTE: When this autocommand is executed, the | |
| 495 current buffer "%" may be different from the | |
| 496 buffer being deleted "<afile>". | |
| 1919 | 497 Don't change to another buffer, it will cause |
| 498 problems. | |
| 7 | 499 *BufWrite* *BufWritePre* |
| 500 BufWrite or BufWritePre Before writing the whole buffer to a file. | |
| 501 *BufWriteCmd* | |
| 502 BufWriteCmd Before writing the whole buffer to a file. | |
| 503 Should do the writing of the file and reset | |
| 39 | 504 'modified' if successful, unless '+' is in |
| 505 'cpo' and writing to another file |cpo-+|. | |
| 506 The buffer contents should not be changed. | |
| 3082 | 507 When the command resets 'modified' the undo |
| 508 information is adjusted to mark older undo | |
| 509 states as 'modified', like |:write| does. | |
| 39 | 510 |Cmd-event| |
| 579 | 511 *BufWritePost* |
| 512 BufWritePost After writing the whole buffer to a file | |
| 513 (should undo the commands for BufWritePre). | |
| 6154 | 514 *CmdUndefined* |
| 515 CmdUndefined When a user command is used but it isn't | |
| 516 defined. Useful for defining a command only | |
| 517 when it's used. The pattern is matched | |
| 518 against the command name. Both <amatch> and | |
| 519 <afile> are set to the name of the command. | |
| 520 NOTE: Autocompletion won't work until the | |
| 521 command is defined. An alternative is to | |
| 522 always define the user command and have it | |
| 523 invoke an autoloaded function. See |autoload|. | |

| 577 CompleteDone After Insert mode completion is done. Either | |
| 578 when something was completed or abandoning | |
| 579 completion. |ins-completion| | |
| 6909 | 580 The |v:completed_item| variable contains |
| 581 information about the completed item. | |
| 3682 | 582 |
| 579 | 583 *CursorHold* |
| 584 CursorHold When the user doesn't press a key for the time | |
| 585 specified with 'updatetime'. Not re-triggered | |
| 586 until the user has pressed a key (i.e. doesn't | |
| 587 fire every 'updatetime' ms if you leave Vim to | |
| 588 make some coffee. :) See |CursorHold-example| | |
| 589 for previewing tags. | |
| 590 This event is only triggered in Normal mode. | |
| 1154 | 591 It is not triggered when waiting for a command |
| 592 argument to be typed, or a movement after an | |
| 593 operator. | |
| 610 | 594 While recording the CursorHold event is not |
| 595 triggered. |q| | |
| 6259 | 596 *<CursorHold>* |
| 597 Internally the autocommand is triggered by the | |
| 598 <CursorHold> key. In an expression mapping | |
| 599 |getchar()| may see this character. | |
| 600 | |
| 579 | 601 Note: Interactive commands cannot be used for |
| 602 this event. There is no hit-enter prompt, | |
| 603 the screen is updated directly (when needed). | |
| 604 Note: In the future there will probably be | |
| 605 another option to set the time. | |
| 606 Hint: to force an update of the status lines | |
| 607 use: > | |
| 608 :let &ro = &ro | |
| 609 < {only on Amiga, Unix, Win32, MSDOS and all GUI | |
| 610 versions} | |
| 661 | 611 *CursorHoldI* |
| 612 CursorHoldI Just like CursorHold, but in Insert mode. | |

| 645 file. Can be used to check-out the file from | |
| 646 a source control system. Not triggered when | |
| 647 the change was caused by an autocommand. | |
| 648 This event is triggered when making the first | |
| 649 change in a buffer or the first change after | |
| 823 | 650 'readonly' was set, just before the change is |
| 651 applied to the text. | |
| 579 | 652 WARNING: If the autocommand moves the cursor |
| 653 the effect of the change is undefined. | |
| 819 | 654 *E788* |
| 655 It is not allowed to change to another buffer | |
| 656 here. You can reload the buffer but not edit | |

| 681 cancelled if there is a modified buffer that | |
| 682 isn't automatically saved, use |VimLeavePre| | |
| 683 for really exiting. | |
| 7 | 684 *FileChangedShell* |
| 685 FileChangedShell When Vim notices that the modification time of | |
| 686 a file has changed since editing started. | |
| 687 Also when the file attributes of the file | |
| 5908 | 688 change or when the size of the file changes. |
| 689 |timestamp| | |
| 7 | 690 Mostly triggered after executing a shell |
| 691 command, but also with a |:checktime| command | |
| 11473 | 692 or when gvim regains input focus. |
| 7 | 693 This autocommand is triggered for each changed |
| 694 file. It is not used when 'autoread' is set | |
| 695 and the buffer was not changed. If a | |
| 696 FileChangedShell autocommand is present the | |
| 697 warning message and prompt is not given. | |
| 179 | 698 The |v:fcs_reason| variable is set to indicate |
| 699 what happened and |v:fcs_choice| can be used | |
| 700 to tell Vim what to do next. | |
| 7 | 701 NOTE: When this autocommand is executed, the |
| 702 current buffer "%" may be different from the | |
| 11347 | 703 buffer that was changed, which is in "<afile>". |

706 buffer. *E246* *E811* |
| 7 | 707 NOTE: This event never nests, to avoid an |
| 708 endless loop. This means that while executing | |
| 709 commands for the FileChangedShell event no | |
| 710 other FileChangedShell event will be | |
| 711 triggered. | |
| 766 | 712 *FileChangedShellPost* |
| 713 FileChangedShellPost After handling a file that was changed outside | |
| 714 of Vim. Can be used to update the statusline. | |

| 716 FileEncoding Obsolete. It still works and is equivalent | |
| 717 to |EncodingChanged|. | |
| 718 *FileReadCmd* | |
| 719 FileReadCmd Before reading a file with a ":read" command. | |
| 720 Should do the reading of the file. |Cmd-event| | |
| 721 *FileReadPost* | |
| 722 FileReadPost After reading a file with a ":read" command. | |
| 723 Note that Vim sets the '[ and '] marks to the | |
| 724 first and last line of the read. This can be | |
| 725 used to operate on the lines just read. | |

| 768 *FilterWritePre* | |
| 769 FilterWritePre Before writing a file for a filter command or | |
| 15334 | 770 making a diff with an external diff. |
| 579 | 771 Vim checks the pattern against the name of |

| 784 dialog pops up. | |
| 7 | 785 *FuncUndefined* |
| 786 FuncUndefined When a user function is used but it isn't | |
| 787 defined. Useful for defining a function only | |
| 1154 | 788 when it's used. The pattern is matched |
| 789 against the function name. Both <amatch> and | |
| 790 <afile> are set to the name of the function. | |
| 6154 | 791 NOTE: When writing Vim scripts a better |
| 792 alternative is to use an autoloaded function. | |
| 161 | 793 See |autoload-functions|. |
| 579 | 794 *GUIEnter* |
| 795 GUIEnter After starting the GUI successfully, and after | |
| 796 opening the window. It is triggered before | |
| 797 VimEnter when using gvim. Can be used to | |
| 798 position the window from a .gvimrc file: > | |
| 799 :autocmd GUIEnter * winpos 100 50 | |

| 805 :autocmd GUIFailed * qall | |
| 579 | 806 < *InsertChange* |
| 807 InsertChange When typing <Insert> while in Insert or | |
| 808 Replace mode. The |v:insertmode| variable | |

| 814 before inserting the char. | |
| 815 The |v:char| variable indicates the char typed | |
| 816 and can be changed during the event to insert | |
| 817 a different character. When |v:char| is set | |
| 818 to more than one character this text is | |
| 819 inserted literally. | |
| 820 It is not allowed to change the text |textlock|. | |
| 821 The event is not triggered when 'paste' is | |
| 13437 | 822 set. {only with the +eval feature} |
| 579 | 823 *InsertEnter* |
| 1154 | 824 InsertEnter Just before starting Insert mode. Also for |
| 825 Replace mode and Virtual Replace mode. The | |
| 579 | 826 |v:insertmode| variable indicates the mode. |
| 4448 | 827 Be careful not to do anything else that the |
| 828 user does not expect. | |
| 829 The cursor is restored afterwards. If you do | |
| 830 not want that set |v:char| to a non-empty | |
| 831 string. | |
| 579 | 832 *InsertLeave* |
| 833 InsertLeave When leaving Insert mode. Also when using | |
| 834 CTRL-O |i_CTRL-O|. But not for |i_CTRL-C|. | |

| 906 RemoteReply When a reply from a Vim that functions as | |

| 908 pattern is matched against the {serverid}. | |
| 579 | 909 <amatch> is equal to the {serverid} from which |
| 910 the reply was sent, and <afile> is the actual | |
| 911 reply string. | |
| 912 Note that even if an autocommand is defined, | |
| 913 the reply should be read with |remote_read()| | |
| 914 to consume it. | |
| 915 *SessionLoadPost* | |
| 916 SessionLoadPost After loading the session file created using | |
| 917 the |:mksession| command. | |

| 1061 | 935 *SourceCmd* |
| 936 SourceCmd When sourcing a Vim script. |:source| | |

| 938 The autocommand must source this file. | |
| 939 |Cmd-event| | |
| 650 | 940 *SpellFileMissing* |
| 941 SpellFileMissing When trying to load a spell checking file and | |
| 1061 | 942 it can't be found. The pattern is matched |
| 943 against the language. <amatch> is the | |
| 944 language, 'encoding' also matters. See | |
| 650 | 945 |spell-SpellFileMissing|. |
| 579 | 946 *StdinReadPost* |
| 947 StdinReadPost After reading from the stdin into the buffer, | |
| 948 before executing the modelines. Only used | |
| 949 when the "-" argument was used when Vim was | |
| 950 started |--|. | |
| 951 *StdinReadPre* | |
| 952 StdinReadPre Before reading from stdin into the buffer. | |
| 953 Only used when the "-" argument was used when | |
| 954 Vim was started |--|. | |
| 955 *SwapExists* | |
| 956 SwapExists Detected an existing swap file when starting | |
| 957 to edit a file. Only when it is possible to | |
| 958 select a way to handle the situation, when Vim | |
| 959 would ask the user what to do. | |
| 960 The |v:swapname| variable holds the name of | |
| 590 | 961 the swap file found, <afile> the file being |
| 962 edited. |v:swapcommand| may contain a command | |
| 963 to be executed in the opened file. | |
| 964 The commands should set the |v:swapchoice| | |
| 965 variable to a string with one character to | |
| 966 tell Vim what should be done next: | |
| 579 | 967 'o' open read-only |
| 968 'e' edit the file anyway | |
| 969 'r' recover | |
| 970 'd' delete the swap file | |
| 971 'q' quit, don't edit the file | |
| 972 'a' abort, like hitting CTRL-C | |
| 973 When set to an empty string the user will be | |
| 974 asked, as if there was no SwapExists autocmd. | |
| 1919 | 975 *E812* |
| 976 It is not allowed to change to another buffer, | |
| 977 change a buffer name or change directory | |
| 978 here. | |
| 13437 | 979 {only available with the +eval feature} |
| 579 | 980 *Syntax* |
| 1154 | 981 Syntax When the 'syntax' option has been set. The |
| 982 pattern is matched against the syntax name. | |
| 579 | 983 <afile> can be used for the name of the file |
| 984 where this option was set, and <amatch> for | |
| 985 the new value of 'syntax'. | |
| 986 See |:syn-on|. | |

| 1129 6. Patterns *autocmd-patterns* *{pat}* | |
| 1130 | |
| 6741 | 1131 The {pat} argument can be a comma separated list. This works as if the |
| 1132 command was given with each pattern separately. Thus this command: > | |
| 1133 :autocmd BufRead *.txt,*.info set et | |
| 1134 Is equivalent to: > | |
| 1135 :autocmd BufRead *.txt set et | |
| 1136 :autocmd BufRead *.info set et | |
| 1137 | |
| 7 | 1138 The file pattern {pat} is tested for a match against the file name in one of |
| 1139 two ways: | |
| 1140 1. When there is no '/' in the pattern, Vim checks for a match against only | |
| 1141 the tail part of the file name (without its leading directory path). | |

1144 it to a full path and resolving symbolic links). |
| 7 | 1145 |
| 40 | 1146 The special pattern <buffer> or <buffer=N> is used for buffer-local |
| 1147 autocommands |autocmd-buflocal|. This pattern is not matched against the name | |
| 1148 of a buffer. | |
| 1149 | |
| 7 | 1150 Examples: > |
| 1151 :autocmd BufRead *.txt set et | |
| 1152 Set the 'et' option for all text files. > | |
| 1153 | |
| 1154 :autocmd BufRead /vim/src/*.c set cindent | |
| 1155 Set the 'cindent' option for C files in the /vim/src directory. > | |
| 1156 | |
| 1157 :autocmd BufRead /tmp/*.c set ts=5 | |
| 1158 If you have a link from "/tmp/test.c" to "/home/nobody/vim/src/test.c", and | |
| 1159 you start editing "/tmp/test.c", this autocommand will match. | |
| 1160 | |
| 1161 Note: To match part of a path, but not from the root directory, use a '*' as | |
| 1162 the first character. Example: > | |
| 1163 :autocmd BufRead */doc/*.txt set tw=78 | |
| 1164 This autocommand will for example be executed for "/tmp/doc/xx.txt" and | |
| 1165 "/usr/home/piet/doc/yy.txt". The number of directories does not matter here. | |
| 1166 | |
| 1167 | |
| 1168 The file name that the pattern is matched against is after expanding | |
| 1621 | 1169 wildcards. Thus if you issue this command: > |
| 7 | 1170 :e $ROOTDIR/main.$EXT |
| 1171 The argument is first expanded to: > | |
| 1172 /usr/root/main.py | |
| 1173 Before it's matched with the pattern of the autocommand. Careful with this | |
| 1174 when using events like FileReadCmd, the value of <amatch> may not be what you | |
| 1175 expect. | |
| 1176 | |
| 1177 | |
| 1178 Environment variables can be used in a pattern: > | |
| 1179 :autocmd BufRead $VIMRUNTIME/doc/*.txt set expandtab | |
| 1180 And ~ can be used for the home directory (if $HOME is defined): > | |
| 1181 :autocmd BufWritePost ~/.vimrc so ~/.vimrc | |
| 1182 :autocmd BufRead ~archive/* set readonly | |
| 1183 The environment variable is expanded when the autocommand is defined, not when | |
| 1184 the autocommand is executed. This is different from the command! | |
| 1185 | |
| 1186 *file-pattern* | |
| 1187 The pattern is interpreted like mostly used in file names: | |
| 5294 | 1188 * matches any sequence of characters; Unusual: includes path |
| 5277 | 1189 separators |
| 7 | 1190 ? matches any single character |
| 1191 \? matches a '?' | |
| 1192 . matches a '.' | |
| 1193 ~ matches a '~' | |
| 1194 , separates patterns | |
| 1195 \, matches a ',' | |
| 1196 { } like \( \) in a |pattern| | |
| 1197 , inside { }: like \| in a |pattern| | |

| 1205 Note that for all systems the '/' character is used for path separator (even | |
| 1206 MS-DOS and OS/2). This was done because the backslash is difficult to use | |
| 1207 in a pattern and to make the autocommands portable across different systems. | |

| 40 | 1212 *autocmd-changes* |
| 7 | 1213 Matching with the pattern is done when an event is triggered. Changing the |
| 1214 buffer name in one of the autocommands, or even deleting the buffer, does not | |
| 1215 change which autocommands will be executed. Example: > | |
| 1216 | |
| 1217 au BufEnter *.foo bdel | |
| 1218 au BufEnter *.foo set modified | |
| 1219 | |
| 1220 This will delete the current buffer and then set 'modified' in what has become | |
| 1221 the current buffer instead. Vim doesn't take into account that "*.foo" | |
| 1222 doesn't match with that buffer name. It matches "*.foo" with the name of the | |
| 1223 buffer at the moment the event was triggered. | |
| 1224 | |
| 40 | 1225 However, buffer-local autocommands will not be executed for a buffer that has |
| 1226 been wiped out with |:bwipe|. After deleting the buffer with |:bdel| the | |
| 1227 buffer actually still exists (it becomes unlisted), thus the autocommands are | |
| 1228 still executed. | |
| 1229 | |
| 7 | 1230 ============================================================================== |
| 856 | 1231 7. Buffer-local autocommands *autocmd-buflocal* *autocmd-buffer-local* |
| 1232 *<buffer=N>* *<buffer=abuf>* *E680* | |
| 40 | 1233 |
| 1234 Buffer-local autocommands are attached to a specific buffer. They are useful | |
| 1235 if the buffer does not have a name and when the name does not match a specific | |
| 1236 pattern. But it also means they must be explicitly added to each buffer. | |
| 1237 | |
| 1238 Instead of a pattern buffer-local autocommands use one of these forms: | |
| 1239 <buffer> current buffer | |
| 1240 <buffer=99> buffer number 99 | |
| 1241 <buffer=abuf> using <abuf> (only when executing autocommands) | |
| 1242 |<abuf>| | |
| 1243 | |
| 1244 Examples: > | |
| 1245 :au CursorHold <buffer> echo 'hold' | |
| 1246 :au CursorHold <buffer=33> echo 'hold' | |

1247 :au BufNewFile * au CursorHold <buffer=abuf> echo 'hold' |
| 40 | 1248 |
| 1249 All the commands for autocommands also work with buffer-local autocommands, | |
| 1250 simply use the special string instead of the pattern. Examples: > | |
| 856 | 1251 :au! * <buffer> " remove buffer-local autocommands for |
| 1252 " current buffer | |
| 1253 :au! * <buffer=33> " remove buffer-local autocommands for | |
| 1254 " buffer #33 | |
| 1621 | 1255 :bufdo :au! CursorHold <buffer> " remove autocmd for given event for all |
| 856 | 1256 " buffers |
| 1257 :au * <buffer> " list buffer-local autocommands for | |
| 1258 " current buffer | |
| 40 | 1259 |
| 1260 Note that when an autocommand is defined for the current buffer, it is stored | |
| 1261 with the buffer number. Thus it uses the form "<buffer=12>", where 12 is the | |
| 1262 number of the current buffer. You will see this when listing autocommands, | |
| 1263 for example. | |
| 1264 | |
| 1265 To test for presence of buffer-local autocommands use the |exists()| function | |
| 1266 as follows: > | |
| 1267 :if exists("#CursorHold#<buffer=12>") | ... | endif | |
| 1268 :if exists("#CursorHold#<buffer>") | ... | endif " for current buffer | |
| 1269 | |
| 1270 When a buffer is wiped out its buffer-local autocommands are also gone, of | |
| 1271 course. Note that when deleting a buffer, e.g., with ":bdel", it is only | |
| 1272 unlisted, the autocommands are still present. In order to see the removal of | |
| 1273 buffer-local autocommands: > | |
| 1274 :set verbose=6 | |
| 1275 | |
| 1276 It is not possible to define buffer-local autocommands for a non-existent | |
| 1277 buffer. | |
| 1278 | |
| 1279 ============================================================================== | |
| 1280 8. Groups *autocmd-groups* | |
| 7 | 1281 |
| 1282 Autocommands can be put together in a group. This is useful for removing or | |
| 1283 executing a group of autocommands. For example, all the autocommands for | |
| 1284 syntax highlighting are put in the "highlight" group, to be able to execute | |
| 1285 ":doautoall highlight BufRead" when the GUI starts. | |
| 1286 | |
| 1287 When no specific group is selected, Vim uses the default group. The default | |
| 1288 group does not have a name. You cannot execute the autocommands from the | |
| 1289 default group separately; you can execute them only by executing autocommands | |
| 1290 for all groups. | |
| 1291 | |
| 1292 Normally, when executing autocommands automatically, Vim uses the autocommands | |
| 1293 for all groups. The group only matters when executing autocommands with | |
| 1294 ":doautocmd" or ":doautoall", or when defining or deleting autocommands. | |
| 1295 | |
| 1296 The group name can contain any characters except white space. The group name | |
| 1297 "end" is reserved (also in uppercase). | |
| 1298 | |
| 1299 The group name is case sensitive. Note that this is different from the event | |
| 1300 name! | |
| 1301 | |
| 1302 *:aug* *:augroup* | |
| 1303 :aug[roup] {name} Define the autocmd group name for the | |
| 1304 following ":autocmd" commands. The name "end" | |
| 1305 or "END" selects the default group. | |

1315 you will get error E936. |

| 1317 To enter autocommands for a specific group, use this method: | |
| 1318 1. Select the group with ":augroup {name}". | |
| 1319 2. Delete any old autocommands with ":au!". | |
| 1320 3. Define the autocommands. | |
| 1321 4. Go back to the default group with "augroup END". | |
| 1322 | |
| 1323 Example: > | |
| 1324 :augroup uncompress | |
| 1325 : au! | |
| 1326 : au BufEnter *.gz %!gunzip | |
| 1327 :augroup END | |
| 1328 | |
| 1329 This prevents having the autocommands defined twice (e.g., after sourcing the | |
| 1330 .vimrc file again). | |
| 1331 | |
| 1332 ============================================================================== | |
| 40 | 1333 9. Executing autocommands *autocmd-execute* |
| 7 | 1334 |
| 1335 Vim can also execute Autocommands non-automatically. This is useful if you | |
| 1336 have changed autocommands, or when Vim has executed the wrong autocommands | |
| 1337 (e.g., the file pattern match was wrong). | |
| 1338 | |
| 1339 Note that the 'eventignore' option applies here too. Events listed in this | |
| 1340 option will not cause any commands to be executed. | |
| 1341 | |
| 1342 *:do* *:doau* *:doautocmd* *E217* | |
| 3356 | 1343 :do[autocmd] [<nomodeline>] [group] {event} [fname] |
| 7 | 1344 Apply the autocommands matching [fname] (default: |
| 1345 current file name) for {event} to the current buffer. | |
| 1346 You can use this when the current file name does not | |
| 1347 match the right pattern, after changing settings, or | |
| 1348 to execute autocommands for a certain event. | |
| 1349 It's possible to use this inside an autocommand too, | |
| 1350 so you can base the autocommands for one extension on | |
| 1351 another extension. Example: > | |
| 3224 | 1352 :au BufEnter *.cpp so ~/.vimrc_cpp |
| 1353 :au BufEnter *.cpp doau BufEnter x.c | |
| 7 | 1354 < Be careful to avoid endless loops. See |
| 1355 |autocmd-nested|. | |
| 1356 | |
| 1357 When the [group] argument is not given, Vim executes | |
| 1358 the autocommands for all groups. When the [group] | |
| 1359 argument is included, Vim executes only the matching | |
| 1360 autocommands for that group. Note: if you use an | |
| 1361 undefined group name, Vim gives you an error message. | |
| 3350 | 1362 *<nomodeline>* |
| 1363 After applying the autocommands the modelines are | |
| 1364 processed, so that their settings overrule the | |
| 1365 settings from autocommands, like what happens when | |
| 1366 editing a file. This is skipped when the <nomodeline> | |
| 1367 argument is present. You probably want to use | |
| 1368 <nomodeline> for events that are not used when loading | |
| 1369 a buffer, such as |User|. | |

1376 loaded buffer. Note that [fname] is used to select |
| 7 | 1377 the autocommands, not the buffers to which they are |
| 1378 applied. | |
| 1379 Careful: Don't use this for autocommands that delete a | |
| 1380 buffer, change to another buffer or change the | |
| 1381 contents of a buffer; the result is unpredictable. | |
| 1382 This command is intended for autocommands that set | |
| 1383 options, change highlighting, and things like that. | |
| 1384 | |
| 1385 ============================================================================== | |
| 40 | 1386 10. Using autocommands *autocmd-use* |
| 7 | 1387 |
| 1388 For WRITING FILES there are four possible sets of events. Vim uses only one | |
| 1389 of these sets for a write command: | |
| 1390 | |
| 1391 BufWriteCmd BufWritePre BufWritePost writing the whole buffer | |
| 1392 FilterWritePre FilterWritePost writing to filter temp file | |
| 1393 FileAppendCmd FileAppendPre FileAppendPost appending to a file | |
| 1394 FileWriteCmd FileWritePre FileWritePost any other file write | |
| 1395 | |
| 1396 When there is a matching "*Cmd" autocommand, it is assumed it will do the | |
| 1397 writing. No further writing is done and the other events are not triggered. | |
| 1398 |Cmd-event| | |
| 1399 | |
| 1400 Note that the *WritePost commands should undo any changes to the buffer that | |
| 1401 were caused by the *WritePre commands; otherwise, writing the file will have | |
| 1402 the side effect of changing the buffer. | |
| 1403 | |
| 1404 Before executing the autocommands, the buffer from which the lines are to be | |
| 1405 written temporarily becomes the current buffer. Unless the autocommands | |
| 1406 change the current buffer or delete the previously current buffer, the | |
| 1407 previously current buffer is made the current buffer again. | |
| 1408 | |
| 1409 The *WritePre and *AppendPre autocommands must not delete the buffer from | |
| 1410 which the lines are to be written. | |
| 1411 | |
| 1412 The '[ and '] marks have a special position: | |
| 1413 - Before the *ReadPre event the '[ mark is set to the line just above where | |
| 1414 the new lines will be inserted. | |
| 1415 - Before the *ReadPost event the '[ mark is set to the first line that was | |
| 1416 just read, the '] mark to the last line. | |
| 26 | 1417 - Before executing the *WriteCmd, *WritePre and *AppendPre autocommands the '[ |
| 1418 mark is set to the first line that will be written, the '] mark to the last | |
| 1419 line. | |
| 7 | 1420 Careful: '[ and '] change when using commands that change the buffer. |
| 1421 | |
| 1422 In commands which expect a file name, you can use "<afile>" for the file name | |
| 1423 that is being read |:<afile>| (you can also use "%" for the current file | |
| 1424 name). "<abuf>" can be used for the buffer number of the currently effective | |
| 14123 | 1425 buffer. This also works for buffers that don't have a name. But it doesn't |
| 7 | 1426 work for files without a buffer (e.g., with ":r file"). |
| 1427 | |
| 1428 *gzip-example* | |
| 1429 Examples for reading and writing compressed files: > | |
| 1430 :augroup gzip | |
| 1431 : autocmd! | |
| 1432 : autocmd BufReadPre,FileReadPre *.gz set bin | |
| 1433 : autocmd BufReadPost,FileReadPost *.gz '[,']!gunzip | |
| 1434 : autocmd BufReadPost,FileReadPost *.gz set nobin | |
| 1435 : autocmd BufReadPost,FileReadPost *.gz execute ":doautocmd BufReadPost " . expand("%:r") | |
| 1436 : autocmd BufWritePost,FileWritePost *.gz !mv <afile> <afile>:r | |
| 1437 : autocmd BufWritePost,FileWritePost *.gz !gzip <afile>:r | |
| 1438 | |
| 1439 : autocmd FileAppendPre *.gz !gunzip <afile> | |
| 1440 : autocmd FileAppendPre *.gz !mv <afile>:r <afile> | |
| 1441 : autocmd FileAppendPost *.gz !mv <afile> <afile>:r | |
| 1442 : autocmd FileAppendPost *.gz !gzip <afile>:r | |
| 1443 :augroup END | |
| 1444 | |
| 1445 The "gzip" group is used to be able to delete any existing autocommands with | |
| 1446 ":autocmd!", for when the file is sourced twice. | |
| 1447 | |
| 1448 ("<afile>:r" is the file name without the extension, see |:_%:|) | |
| 1449 | |
| 1450 The commands executed for the BufNewFile, BufRead/BufReadPost, BufWritePost, | |
| 1451 FileAppendPost and VimLeave events do not set or reset the changed flag of the | |
| 1452 buffer. When you decompress the buffer with the BufReadPost autocommands, you | |
| 1453 can still exit with ":q". When you use ":undo" in BufWritePost to undo the | |
| 1454 changes made by BufWritePre commands, you can still do ":q" (this also makes | |
| 1455 "ZZ" work). If you do want the buffer to be marked as modified, set the | |
| 1456 'modified' option. | |
| 1457 | |
| 1458 To execute Normal mode commands from an autocommand, use the ":normal" | |
| 1459 command. Use with care! If the Normal mode command is not finished, the user | |
| 1460 needs to type characters (e.g., after ":normal m" you need to type a mark | |
| 1461 name). | |
| 1462 | |
| 1463 If you want the buffer to be unmodified after changing it, reset the | |
| 1464 'modified' option. This makes it possible to exit the buffer with ":q" | |
| 1465 instead of ":q!". | |
| 1466 | |
| 1467 *autocmd-nested* *E218* | |
| 1468 By default, autocommands do not nest. If you use ":e" or ":w" in an | |
| 1469 autocommand, Vim does not execute the BufRead and BufWrite autocommands for | |
| 1470 those commands. If you do want this, use the "nested" flag for those commands | |
| 1471 in which you want nesting. For example: > | |
| 1472 :autocmd FileChangedShell *.c nested e! | |
| 1473 The nesting is limited to 10 levels to get out of recursive loops. | |
| 1474 | |
| 1475 It's possible to use the ":au" command in an autocommand. This can be a | |
| 1476 self-modifying command! This can be useful for an autocommand that should | |
| 1477 execute only once. | |
| 1478 | |
| 590 | 1479 If you want to skip autocommands for one command, use the |:noautocmd| command |
| 1480 modifier or the 'eventignore' option. | |
| 7 | 1481 |
| 1482 Note: When reading a file (with ":read file" or with a filter command) and the | |
| 1483 last line in the file does not have an <EOL>, Vim remembers this. At the next | |
| 1484 write (with ":write file" or with a filter command), if the same line is | |
| 1485 written again as the last line in a file AND 'binary' is set, Vim does not | |
| 1486 supply an <EOL>. This makes a filter command on the just read lines write the | |
| 1487 same file as was read, and makes a write command on just filtered lines write | |
| 1488 the same file as was read from the filter. For example, another way to write | |
| 1489 a compressed file: > | |
| 1490 | |
| 1491 :autocmd FileWritePre *.gz set bin|'[,']!gzip | |
| 1492 :autocmd FileWritePost *.gz undo|set nobin | |
| 1493 < | |
| 1494 *autocommand-pattern* | |
| 1495 You can specify multiple patterns, separated by commas. Here are some | |
| 1496 examples: > | |
| 1497 | |
| 1498 :autocmd BufRead * set tw=79 nocin ic infercase fo=2croq | |
| 1499 :autocmd BufRead .letter set tw=72 fo=2tcrq | |
| 1500 :autocmd BufEnter .letter set dict=/usr/lib/dict/words | |
| 1501 :autocmd BufLeave .letter set dict= | |
| 1502 :autocmd BufRead,BufNewFile *.c,*.h set tw=0 cin noic | |
| 1503 :autocmd BufEnter *.c,*.h abbr FOR for (i = 0; i < 3; ++i)<CR>{<CR>}<Esc>O | |
| 1504 :autocmd BufLeave *.c,*.h unabbr FOR | |
| 1505 | |
| 1506 For makefiles (makefile, Makefile, imakefile, makefile.unix, etc.): > | |
| 1507 | |
| 1508 :autocmd BufEnter ?akefile* set include=^s\=include | |
| 1509 :autocmd BufLeave ?akefile* set include& | |
| 1510 | |
| 1511 To always start editing C files at the first function: > | |
| 1512 | |
| 1513 :autocmd BufRead *.c,*.h 1;/^{ | |
| 1514 | |
| 1515 Without the "1;" above, the search would start from wherever the file was | |
| 1516 entered, rather than from the start of the file. | |
| 1517 | |
| 1518 *skeleton* *template* | |
| 1519 To read a skeleton (template) file when opening a new file: > | |
| 1520 | |
| 1521 :autocmd BufNewFile *.c 0r ~/vim/skeleton.c | |
| 1522 :autocmd BufNewFile *.h 0r ~/vim/skeleton.h | |
| 1523 :autocmd BufNewFile *.java 0r ~/vim/skeleton.java | |
| 1524 | |
| 1525 To insert the current date and time in a *.html file when writing it: > | |
| 1526 | |
| 1527 :autocmd BufWritePre,FileWritePre *.html ks|call LastMod()|'s | |
| 1528 :fun LastMod() | |
| 1529 : if line("$") > 20 | |
| 1530 : let l = 20 | |
| 1531 : else | |
| 1532 : let l = line("$") | |
| 1533 : endif | |
| 1534 : exe "1," . l . "g/Last modified: /s/Last modified: .*/Last modified: " . | |
| 1535 : \ strftime("%Y %b %d") | |
| 1536 :endfun | |
| 1537 | |
| 1538 You need to have a line "Last modified: <date time>" in the first 20 lines | |
| 1539 of the file for this to work. Vim replaces <date time> (and anything in the | |
| 1540 same line after it) with the current date and time. Explanation: | |
| 1541 ks mark current position with mark 's' | |
| 1542 call LastMod() call the LastMod() function to do the work | |
| 1543 's return the cursor to the old position | |
| 1544 The LastMod() function checks if the file is shorter than 20 lines, and then | |
| 1545 uses the ":g" command to find lines that contain "Last modified: ". For those | |
| 1546 lines the ":s" command is executed to replace the existing date with the | |
| 1547 current one. The ":execute" command is used to be able to use an expression | |
| 1548 for the ":g" and ":s" commands. The date is obtained with the strftime() | |
| 1549 function. You can change its argument to get another date string. | |
| 1550 | |
| 1551 When entering :autocmd on the command-line, completion of events and command | |
| 1552 names may be done (with <Tab>, CTRL-D, etc.) where appropriate. | |
| 1553 | |
| 1554 Vim executes all matching autocommands in the order that you specify them. | |
| 1555 It is recommended that your first autocommand be used for all files by using | |
| 1556 "*" as the file pattern. This means that you can define defaults you like | |
| 1557 here for any settings, and if there is another matching autocommand it will | |
| 1558 override these. But if there is no other matching autocommand, then at least | |
| 1559 your default settings are recovered (if entering this file from another for | |
| 1560 which autocommands did match). Note that "*" will also match files starting | |
| 1561 with ".", unlike Unix shells. | |
| 1562 | |
| 1563 *autocmd-searchpat* | |
| 1564 Autocommands do not change the current search patterns. Vim saves the current | |
| 1565 search patterns before executing autocommands then restores them after the | |
| 1566 autocommands finish. This means that autocommands do not affect the strings | |
| 1567 highlighted with the 'hlsearch' option. Within autocommands, you can still | |
| 1568 use search patterns normally, e.g., with the "n" command. | |
| 1569 If you want an autocommand to set the search pattern, such that it is used | |
| 1570 after the autocommand finishes, use the ":let @/ =" command. | |
| 1571 The search-highlighting cannot be switched off with ":nohlsearch" in an | |
| 1572 autocommand. Use the 'h' flag in the 'viminfo' option to disable search- | |
| 1573 highlighting when starting Vim. | |
| 1574 | |
| 1575 *Cmd-event* | |
| 1576 When using one of the "*Cmd" events, the matching autocommands are expected to | |
| 1061 | 1577 do the file reading, writing or sourcing. This can be used when working with |
| 1578 a special kind of file, for example on a remote system. | |
| 7 | 1579 CAREFUL: If you use these events in a wrong way, it may have the effect of |
| 1580 making it impossible to read or write the matching files! Make sure you test | |
| 1581 your autocommands properly. Best is to use a pattern that will never match a | |
| 1582 normal file name, for example "ftp://*". | |
| 1583 | |
| 1584 When defining a BufReadCmd it will be difficult for Vim to recover a crashed | |
| 1585 editing session. When recovering from the original file, Vim reads only those | |
| 1586 parts of a file that are not found in the swap file. Since that is not | |
| 1587 possible with a BufReadCmd, use the |:preserve| command to make sure the | |
| 1588 original file isn't needed for recovery. You might want to do this only when | |
| 1589 you expect the file to be modified. | |
| 1590 | |
| 1061 | 1591 For file read and write commands the |v:cmdarg| variable holds the "++enc=" |
| 1592 and "++ff=" argument that are effective. These should be used for the command | |
| 1593 that reads/writes the file. The |v:cmdbang| variable is one when "!" was | |
| 1594 used, zero otherwise. | |

| 1599 11. Disabling autocommands *autocmd-disable* | |
| 1600 | |
| 1601 To disable autocommands for some time use the 'eventignore' option. Note that | |
| 1602 this may cause unexpected behavior, make sure you restore 'eventignore' | |
| 1603 afterwards, using a |:try| block with |:finally|. | |
| 1604 | |
| 1605 *:noautocmd* *:noa* | |
| 1606 To disable autocommands for just one command use the ":noautocmd" command | |
| 1607 modifier. This will set 'eventignore' to "all" for the duration of the | |
| 1608 following command. Example: > | |
| 1609 | |
| 1610 :noautocmd w fname.gz | |
| 1611 | |
| 1612 This will write the file without triggering the autocommands defined by the | |
| 1613 gzip plugin. | |
