配置自动缩减

set nu

set autoindent
set cindent
set shiftwidth=4
set softtabstop=4
set tabstop=4

具体含义：

命令	含义
nu	添加行号
autoindent	自动缩进
cindent	按照c语言语法缩进
shiftwidth	自动缩进空白字符个数
softtabstop	tab键的一个制表符，如果softtabstop=5,tabstop=4,则tab是1个制表符加1个空格的混合
tabstop	tab键的空格数

添加左分屏

左分屏用来显示当前文件夹下的所有文件。

" NERD tree
let NERDChristmasTree=0
let NERDTreeWinSize=35
let NERDTreeChDirMode=2
let NERDTreeIgnore=['\~$', '\.pyc$', '\.swp$']
let NERDTreeShowBookmarks=1
let NERDTreeWinPos="left"
" Automatically open a NERDTree if no files where specified
autocmd vimenter * if !argc() | NERDTree | endif
" Close vim if the only window left open is a NERDTree
autocmd bufenter * if (winnr("$") == 1 && exists("b:NERDTreeType") && b:NERDTreeType == "primary") | q | endif
" Open a NERDTree
nmap <F5> :NERDTreeToggle<cr>

使用F5来开启和关闭该功能。

添加右分屏

右分屏用来显示当前文件中的函数名，和全局对象名。

" Tagbar
let g:tagbar_width=35
let g:tagbar_autofocus=1
nmap <F6> :TagbarToggle<CR>

添加代码折叠

功能方法有待改善。。。不太好用

" Enable folding
set fdm=indent

" Enable folding with the spacebar
nnoremap <space> za

通过<space>键来展开和折叠代码块。

添加自动补全功能

该功能的使用需要安装YouCompleteMe。使用的是vbundle来管理插件。

set completeopt=longest,menu    "让Vim的补全菜单行为与一般IDE一致(参考VimTip1228)"
set runtimepath+=~/.vim/bundle/YouCompleteMe
autocmd InsertLeave * if pumvisible() == 0|pclose|endif "离开插入模式后自动关闭预览窗口"

let g:ycm_complete_in_comments = 1
let g:ycm_confirm_extra_conf = 0
let g:ycm_key_list_select_completion = ['<c-n>', '<Down>']  " 映射按键, 没有这个会拦截掉tab, 导致其他插>件的tab不能用.
let g:ycm_key_list_previous_completion = ['<c-p>', '<Up>']
let g:ycm_complete_in_comments = 1                          " 在注释输入中也能补全

let g:ycm_global_ycm_extra_conf='~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp/ycm/.ycm_extra_conf.py'
let g:ycm_show_diagnostics_ui = 0                           " 禁用语法检查

nnoremap <F3> :YcmCompleter GoToDefinitionElseDeclaration<CR>|
let g:ycm_min_num_of_chars_for_completion=2
