Ctrl-n完成需要很长时间才能“扫描包含的文件”

#1 楼

默认情况下，当您按下C-n或C-p时，Vim会在各种来源中查找要填充完成菜单的候选者。

这些来源可以使用本地缓冲区'complete'选项进行配置。

此选项的值是一个用逗号分隔的标志列表。每个标志在:h 'cpt中都有其自己的含义：

.   scan the current buffer ('wrapscan' is ignored)
w   scan buffers from other windows
b   scan other loaded buffers that are in the buffer list
u   scan the unloaded buffers that are in the buffer list
U   scan the buffers that are not in the buffer list
k   scan the files given with the 'dictionary' option
kspell  use the currently active spell checking |spell|
k{dict} scan the file {dict}.  Several "k" flags can be given, patterns are valid too.  For example:  
        :set cpt=k/usr/dict/*,k~/spanish
s   scan the files given with the 'thesaurus' option
s{tsr}  scan the file {tsr}.  Several "s" flags can be given, patterns are valid too.
i   scan current and included files
d   scan current and included files for defined name or macro |i_CTRL-X_CTRL-D|
]   tag completion
t   same as "]"

默认情况下，其值为.,w,b,u,t,i，表示：

   1. the current buffer
   2. buffers in other windows
   3. other loaded buffers
   4. unloaded buffers
   5. tags
   6. included files

如果发现扫描包含的文件花费太多时间，则可以尝试从i选项中删除'cpt'标志。

如果要将其从全局值中删除，要影响默认情况下的所有缓冲区，您可以在vimrc中进行写：在perl内的一个autocmd： br />

setglobal complete-=i

要查看vimrc选项的当前全局值和局部值以及它们的最后设置位置，可以使用以下命令：

augroup PerlSettings
    autocmd!
    autocmd FileType perl setlocal complete-=i
augroup END

或更短：

setlocal complete-=i

如果唯一感兴趣的源是当前缓冲区，那么可以使用~/.vim/after/ftplugin/perl.vim代替'complete'。有关更多信息，请参见C-n。
