Vim使用Vundle安裝代碼補全插件（YouCompleteMe）

安裝 Vundle

它的使用方法很簡單，安裝一個插件只須要在 ~/.vimrc 按照規則中添加 Plugin 的名稱，某些須要添加路徑，以後在 Vim 中使用:PluginInstall既能夠自動化安裝。

一、先新建目錄

mkdir ~/.vim/bundle/Vundle.vim

二、git 克隆 Vundle 工程到本地

git clone https://github.com/gmarik/Vundle.vim.git ~/.vim/bundle/Vundle.vim

 三、修改 ~/.vimrc 配置 Plugins。在 ~/.vimrc 文件中添加以下內容並保存

set nocompatible " be iMproved, required
filetype off " required

" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim call vundle#begin() " alternatively, pass a path where Vundle should install plugins "call vundle#begin('~/some/path/here')

" let Vundle manage Vundle, required
Plugin 'VundleVim/Vundle.vim'

" The following are examples of different formats supported. " Keep Plugin commands between vundle#begin/end.

" All of your Plugins must be added before the following line
call vundle#end() " required
filetype plugin indent on " required " To ignore plugin indent changes, instead use: "filetype plugin on " " Brief help " :PluginList - lists configured plugins " :PluginInstall - installs plugins; append `!` to update or just :PluginUpdate " :PluginSearch foo - searches for foo; append `!` to refresh local cache " :PluginClean - confirms removal of unused plugins; append `!` to auto-approve removal " " see :h vundle for more details or wiki for FAQ " Put your non-Plugin stuff after this line

四、進入 vim 運行命令

:PluginInstall

Vundle 命令

# 安裝插件 :BundleInstall # 更新插件 :BundleUpdate # 清除不須要的插件 :BundleClean # 列出當前的插件 :BundleList # 搜索插件 :BundleSearch

注意

插件配置不要在 call vundle#end() 以前，否則插件沒法生效
若是配置錯誤，須要從新配置後，在vim中運行命令 :PluginInstall

使用 Vundle 安裝 YouCompleteMe

在 ~/.vimrc 中添加以下內容 位置在call vundle#begin()和call vundle#end()之間

Bundle 'Valloric/YouCompleteMe'

在vim中運行如下命令就會自行安裝，安裝時間有點長，請耐心等待

:BundleInstall

安裝完成後須要編譯 YouCompleteMe

編譯過程須要CMake，沒有安裝CMake可以使用如下命令進行安裝

sudo apt install cmake

而後切換到如下目錄

cd ~/.vim/bundle/YouCompleteMe

最後輸入如下命令便可（默認支持python）

./install.sh

配置 YouCompleteMe

在 ~/.vimrc 中添加配置

" 自動補全配置
set completeopt=longest,menu "讓Vim的補全菜單行爲與通常IDE一致(參考VimTip1228)
autocmd InsertLeave * if pumvisible() == 0|pclose|endif "離開插入模式後自動關閉預覽窗口
inoremap <expr> <CR> pumvisible() ? "\<C-y>" : "\<CR>" "回車即選中當前項 "上下左右鍵的行爲 會顯示其餘信息
inoremap <expr> <Down> pumvisible() ? "\<C-n>" : "\<Down>" inoremap <expr> <Up> pumvisible() ? "\<C-p>" : "\<Up>" inoremap <expr> <PageDown> pumvisible() ? "\<PageDown>\<C-p>\<C-n>" : "\<PageDown>" inoremap <expr> <PageUp> pumvisible() ? "\<PageUp>\<C-p>\<C-n>" : "\<PageUp>"

"youcompleteme 默認tab s-tab 和自動補全衝突 "let g:ycm_key_list_select_completion=['<c-n>']
let g:ycm_key_list_select_completion = ['<Down>'] "let g:ycm_key_list_previous_completion=['<c-p>']
let g:ycm_key_list_previous_completion = ['<Up>'] let g:ycm_confirm_extra_conf=0 "關閉加載.ycm_extra_conf.py提示
 let g:ycm_collect_identifiers_from_tags_files=1 " 開啓 YCM 基於標籤引擎
let g:ycm_min_num_of_chars_for_completion=2 " 從第2個鍵入字符就開始羅列匹配項
let g:ycm_cache_omnifunc=0 " 禁止緩存匹配項,每次都從新生成匹配項
let g:ycm_seed_identifiers_with_syntax=1 " 語法關鍵字補全
nnoremap <F5> :YcmForceCompileAndDiagnostics<CR> "force recomile with syntastic "nnoremap <leader>lo :lopen<CR> "open locationlist "nnoremap <leader>lc :lclose<CR> "close locationlist inoremap <leader><leader> <C-x><C-o>
"在註釋輸入中也能補全
let g:ycm_complete_in_comments = 1
"在字符串輸入中也能補全
let g:ycm_complete_in_strings = 1
"註釋和字符串中的文字也會被收入補全
let g:ycm_collect_identifiers_from_comments_and_strings = 0 nnoremap <leader>jd :YcmCompleter GoToDefinitionElseDeclaration<CR> " 跳轉到定義處

到此，YouCompleteMe 已安裝成功。
