【VIM自动补全】NeoComplCache

NeoComplCache这个自动插件简直屌爆了。用vim.org的官方选项来评价，就是：
Life Changing。

安装也很简单：

1. 下载插件，将里面的文件拷贝到~/vim/vimfile里对应的文件夹下。
2. 在.vimrc文件里加入自动启动的命令：

 let g:neocomplcache_enable_at_startup = 1

   或者运行：

:NeoComplCacheEnable 

   命令。

以上两步官方说明十分齐全。

配置：

"使用带force的选项，使一个键只帮一个作用。比较清爽
" open the snippet
imap <silent><C-l> <Plug>(neocomplcache_snippets_force_expand)
smap <silent><C-l> <Plug>(neocomplcache_snippets_force_expand) 

"jump to next placeholder
imap <silent><C-k> <Plug>(neocomplcache_snippets_force_jump)
smap <silent><C-k> <Plug>(neocomplcache_snippets_force_jump)

" <C-h>, <BS>: close popup and delete backword char.
inoremap <expr><C-h> neocomplcache#smart_close_popup()."\<C-h>" 

 

另外：因为冲突的原因，所以需要额外设置shiftwidth选项

set shiftwidth=4

 否则自动生成的模板缩进为8个空格。这不是一般人想要的。

 

修改snippet的模板：

将大括号从原来的行末变成新起一行，左对齐，可以通过修改snippet模板来实现，路径为

autoload\neocomplcache\sources\snippets_complete\c.snip

修改后的文件如下：

snippet     if
abbr        if () {}
    if (${1:/* condition */}) 
    {
        ${0:/* code */}
    }

snippet else
    else 
    {
        ${0}
    }

snippet elseif
    else if (${1:/* condition */}) 
    {
        ${0}
    }

snippet     ifelse
abbr        if () {} else {}
    if (${1:condition}) 
    {
        ${2}
    } 
    else 
    {
        ${3}
    }

snippet     for
abbr        for () {}
    for (${1} = 0; $1 < ${2}; $1++) 
    {
        ${0}
    }
