每日vim插件--强大的自动补全neocomplete.vim和supertab

vim

#neocomplete.vim

今天介绍两个个必备的vim插件，自动补全插件——neocomplete.vim和superTab。

neocomplete.vim是来自shougo的作品。该插件维护了当前buffer的一个关键词列表，从而提供强大的关键词补全功能。

该插件是他前作neocomplcache的升级版，速度更快，功能更强大。不过该插件需要if_lua的支持。

mac下安装：

brew install macvim --with-cscope --with-lua --HEAD

或者不用macvim（真的不用么？赶紧试试吧）：

brew install vim --with-lua

不需要过多的介绍,看作者给的图：

文件补全

Include filename completion.

Omni 补全

vimshell补全

Vim 补全

作者还给出了推荐配置，每个配置都有对应的英文注释，我就不一一翻译了：

没有特殊需求，直接copy就用即可。没有复杂的配置，用起来还是非常简单的。

还有一个比较出名的补全插件是YouCompleteMe.大家也可以去看下，应该是现在用的最广泛的补全插件了。我很早就试用过，还是neocomplete要更顺手更快些，总感觉neocomplete要更智能些。

#superTab

说到补全还有个不得不说，那就是tab键，必须用tab来进行补全那才是补全啊。其实neocomplete的推荐配置已经配置成了自动提示补全文字，并且支持tab选择，但是还是无法shift-tab回退选择。superTab就是为增强tab而生，当然可以做到这点。

superTab 和neocomplete一样，几乎不用自己折腾什么配置，也不用过多的介绍，一句话就可以说完它的功能。

bar
baz
b*<Tab> (*为光标所在位置)

按示例在光标处按下tab，就会展开推荐补全bar和baz，按tab即可进行循环选择。

可以配置supertab的默认补全类型（对vim补全不了解的同学自己补下omni补全相关知识，需要我介绍可以回复下）：

let g:SuperTabDefaultCompletionType = "<c-x><c-u>"

示例把supertab修改为了用户补全，默认是<c-p>.

今天就介绍到这里。
