使用 tagbar 插件：
  -- 首先安装：brew install ctags
  -- go get -u github.com/jstemmer/gotags
  -- gotags 安装完之后，需要将编译后的 gotags 路径加入到 PATH 路径下，比如在 $GOPATH/bin 下
  -- 加入如下内容到 .vimrc.before.local 中：
    let g:tagbar_type_go = {
    \ 'ctagstype' : 'go',
    \ 'kinds'     : [
        \ 'p:package',
        \ 'i:imports:1',
        \ 'c:constants',
        \ 'v:variables',
        \ 't:types',
        \ 'n:interfaces',
        \ 'w:fields',
        \ 'e:embedded',
        \ 'm:methods',
        \ 'r:constructor',
        \ 'f:functions'
    \ ],
    \ 'sro' : '.',
    \ 'kind2scope' : {
        \ 't' : 'ctype',
        \ 'n' : 'ntype'
    \ },
    \ 'scope2kind' : {
        \ 'ctype' : 't',
        \ 'ntype' : 'n'
    \ },
    \ 'ctagsbin'  : 'gotags',
    \ 'ctagsargs' : '-sort -silent'
    \ }
    

如果出现下面的错误：
neocomplete does not work this version of Vim.
It requires Vim 7.3.885 or above and "if_lua" enabled Vim.
