Autocmd

1. はじめに autocmd-intro

2. autocommandの定義 autocmd-define

:augroup mine | au! BufRead | augroup END

:augroup mine | au! BufRead * | augroup END
:augroup mine | au BufRead * set tw=70 | augroup END

:au! mine BufRead *
:au mine BufRead * set tw=70

:augroup mine | exe "au! BufRead *" | augroup END
:augroup mine | exe "au BufRead * set tw=70" | augroup END

:au BufNewFile,BufRead *.html so <sfile>:h/html.vim

augroup vimrc
  " Remove all vimrc autocommands
  autocmd!
  au BufNewFile,BufRead *.html so <sfile>:h/html.vim
augroup END

:if !exists("autocommands_loaded")
:  let autocommands_loaded = 1
:  au ...
:endif

:set verbose=9

3. autocommandの削除 autocmd! autocmd-remove

4. autocommandのリスト autocmd-list

:verbose autocmd BufEnter
FileExplorer  BufEnter
    *          call s:LocalBrowse(expand("<amatch>"))
        Last set from /usr/share/vim/vim-7.0/plugin/NetrwPlugin.vim

5. イベント autocmd-events E215 E216

:let &ro = &ro

:au ModeChanged [vV\x16]*:* let &l:rnu = mode() =~# '^[vV\x16]'
:au ModeChanged *:[vV\x16]* let &l:rnu = mode() =~# '^[vV\x16]'
:au WinEnter,WinLeave * let &l:rnu = mode() =~# '^[vV\x16]'

autocmd Signal SIGUSR1 call some#func()

-- Query the terminal palette for the RGB value of color 1
-- (red) using OSC 4
vim.api.nvim_create_autocmd('TermResponse', {
  once = true,
  callback = function(args)
    local resp = args.data
    local r, g, b = resp:match("\027%]4;1;rgb:(%w+)/(%w+)/(%w+)")
  end,
})
io.stdout:write("\027]4;1;?\027\\")

:autocmd User MyPlugin echom 'got MyPlugin event'
:doautocmd User MyPlugin

if v:vim_did_enter
  call s:init()
else
  au VimEnter * call s:init()
endif

:autocmd VimLeavePre * call CleanupStuff()

6. パターン autocmd-pattern {aupat}

:autocmd BufRead *.txt,*.info set et

:autocmd BufRead *.txt set et
:autocmd BufRead *.info set et

:autocmd BufRead *.txt                set et

:autocmd BufRead /vim/src/*.c        set cindent

:autocmd BufRead /tmp/*.c        set ts=5

:autocmd BufRead */doc/*.txt        set tw=78

:e $ROOTDIR/main.$EXT

/usr/root/main.py

:autocmd BufRead $VIMRUNTIME/doc/*.txt  set expandtab

:autocmd BufWritePost ~/.config/nvim/init.vim   so <afile>
:autocmd BufRead ~archive/*      set readonly

au BufEnter *.foo  bdel
au BufEnter *.foo  set modified

7. バッファローカル自動コマンド autocmd-buflocal autocmd-buffer-local

:au CursorHold <buffer>  echo 'hold'
:au CursorHold <buffer=33>  echo 'hold'
:au BufNewFile * au CursorHold <buffer=abuf>  echo 'hold'

:au! * <buffer>                     " remove buffer-local autocommands for
                                 " current buffer
:au! * <buffer=33>                     " remove buffer-local autocommands for
                                 " buffer #33
:bufdo :au! CursorHold <buffer>  " remove autocmd for given event for all
                                 " buffers
:au * <buffer>                     " list buffer-local autocommands for
                                 " current buffer

:if exists("#CursorHold#<buffer=12>") | ... | endif
:if exists("#CursorHold#<buffer>") | ... | endif    " for current buffer

:set verbose=6

8. グループ autocmd-groups

:augroup uncompress
:  au!
:  au BufEnter *.gz        %!gunzip
:augroup END

browse edit

9. 自動コマンドの実行 autocmd-execute

:au BufEnter *.cpp so ~/.config/nvim/init_cpp.vim
:au BufEnter *.cpp doau BufEnter x.c

augroup mine
  autocmd!
  autocmd FileType * echo expand('<amatch>')
augroup END
doautoall mine FileType Loaded-Buffer

10. 自動コマンドの使用 autocmd-use

:augroup gzip
:  autocmd!
:  autocmd BufReadPre,FileReadPre        *.gz set bin
:  autocmd BufReadPost,FileReadPost        *.gz '[,']!gunzip
:  autocmd BufReadPost,FileReadPost        *.gz set nobin
:  autocmd BufReadPost,FileReadPost        *.gz execute ":doautocmd BufReadPost " .. expand("%:r")
:  autocmd BufWritePost,FileWritePost        *.gz !mv <afile> <afile>:r
:  autocmd BufWritePost,FileWritePost        *.gz !gzip <afile>:r
:  autocmd FileAppendPre                *.gz !gunzip <afile>
:  autocmd FileAppendPre                *.gz !mv <afile>:r <afile>
:  autocmd FileAppendPost                *.gz !mv <afile> <afile>:r
:  autocmd FileAppendPost                *.gz !gzip <afile>:r
:augroup END

:autocmd FileChangedShell *.c ++nested e!

:autocmd FileWritePre *.gz   set bin|'[,']!gzip
:autocmd FileWritePost *.gz  undo|set nobin

:autocmd BufRead   *                set tw=79 nocin ic infercase fo=2croq
:autocmd BufRead   .letter        set tw=72 fo=2tcrq

:autocmd BufEnter  ?akefile*        set include=^s\=include
:autocmd BufLeave  ?akefile*        set include&

:autocmd BufRead   *.c,*.h        1;/^{

:autocmd BufNewFile  *.h        0r ~/vim/skeleton.h
:autocmd BufNewFile  *.java        0r ~/vim/skeleton.java
