インサートモード時の が use しているファイルの中を検索するからウザイ

vim perl

CPAN モジュールをわんさかインストールしているので、 が非常に重い。
インストールされいてる CPAN モジュールから辞書ファイルを自動生成しているので、辞書ファイルからだけ補完されれば良い。

help cpt を見ると・・・

						*'complete'* *'cpt'* *E535*
'complete' 'cpt'	string	(default: ".,w,b,u,t,i")
			local to buffer
			{not in Vi}
	This option specifies how keyword completion |ins-completion| works
	when CTRL-P or CTRL-N are used.  It is also used for whole-line
	completion |i_CTRL-X_CTRL-L|.  It indicates the type of completion
	and the places to scan.  It is a comma separated list of flags:
	.	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 "]"

	Unloaded buffers are not loaded, thus their autocmds |:autocmd| are
	not executed, this may lead to unexpected completions from some files
	(gzipped files for example).  Unloaded buffers are not scanned for
	whole-line completion.

	The default is ".,w,b,u,t,i", which means to scan:
	   1. the current buffer
	   2. buffers in other windows
	   3. other loaded buffers
	   4. unloaded buffers
	   5. tags
	   6. included files

	As you can see, CTRL-N and CTRL-P can be used to do any 'iskeyword'-
	based expansion (e.g., dictionary |i_CTRL-X_CTRL-K|, included patterns
	|i_CTRL-X_CTRL-I|, tags |i_CTRL-X_CTRL-]| and normal expansions).

って事で、下記を追加。

autocmd FileType perl set complete-=i

ruby とか組んでいる際には便利なんだけどねー。
