自動命令組

• 自動命令組適用於組織，但它們也可用於除錯。將它們視為可以隨意啟用/禁用的小名稱空間。

例

augroup MyGroup
    " Clear the autocmds of the current group to prevent them from piling
    " up each time you reload your vimrc.
    autocmd!

    " These autocmds are fired after the filetype of a buffer is defined to
    " 'foo'. Don't forget to use 'setlocal' (for options) and '<buffer>'
    " (for mappings) to prevent your settings to leak in other buffers with
    " a different filetype.
    autocmd FileType foo setlocal bar=baz
    autocmd FileType foo nnoremap <buffer> <key> :command<CR>

    " This autocmd calls 'MyFunction()' everytime Vim tries to create/edit
    " a buffer tied to a file in /'path/to/project/**/'.
    autocmd BufNew,BufEnter /path/to/project/**/* call MyFunction()
augroup END
