01. YouCompleteMe下载

在gitHub中下载对应的插件

deng@itcast:~$ git clone --recursive git://github.com/Valloric/YouCompleteMe

如果执行该命令没报错, 就ok了. 但是中途有可能会断掉, 可以 cd 到 YouCompleteMe, 然后反复用如下命令再次进行下载:

deng@itcast:~$ git submodule update --init --recursive

02. YouCompleteMe安装

安装

deng@itcast:~/.vim/bundle/YouCompleteMe$ pwd
/home/deng/.vim/bundle/YouCompleteMe
deng@itcast:~/.vim/bundle/YouCompleteMe$ ./install.py --clang-completer

编译结果如下：

如果报Python相关的错误就执行如下命令

deng@itcast:~$ sudo apt install build-essential cmake python3-dev

03. YouCompleteMe配置

在~/.vimrc文件中添加如下内容

" YouCompleteMe
set runtimepath+=~/.vim/bundle/YouCompleteMe
let g:ycm_collect_identifiers_from_tags_files = 1           " 开启 YCM 基于标签引擎
let g:ycm_collect_identifiers_from_comments_and_strings = 1 " 注释与字符串中的内容也用于补全
let g:syntastic_ignore_files=[".*\.py$"]
let g:ycm_seed_identifiers_with_syntax = 1                  " 语法关键字补全
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_complete_in_strings = 1                           " 在字符串输入中也能补全
let g:ycm_collect_identifiers_from_comments_and_strings = 1 " 注释和字符串中的文字也会被收入补全
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
inoremap <expr> <CR> pumvisible() ? "\<C-y>" : "\<CR>" |            " 回车即选中当前项
nnoremap <c-j> :YcmCompleter GoToDefinitionElseDeclaration<CR>|     " 跳转到定义处
"let g:ycm_min_num_of_chars_for_completion=2                 " 从第2个键入字符就开始罗列匹配项

其中 ~/.vim/bundle/YouCompleteMe 为下载 YouCompleteMeu 的路径.

04. YouCompleteMe的使用

• 默认当键入两个字母之后, 则启动补全. 可以通过该变量调整: g:ycm_min_num_of_chars_for_completion
• 也可以使用原有的``来补全, ycm将其功能增强了.
• 按照本文配置, 可用``跳转到定义处.
• 默认配置``会选择补全内容, 本文的配置将其屏蔽了, 为了不会与snipmate等需要tab的冲突, 选择补全改为了.
