Ubuntu 16.04 vim YouCompleteMe自動補全的安裝設定與使用

1 下載

git clone --recursive git://github.com/Valloric/YouCompleteMe

如果執行該命令沒報錯, 就ok了. 但是中途有可能會斷掉, 可以 cd 到 YouCompleteMe, 然後反復用如下命令再次進行下載:

git submodule update --init --recursive

又一回我是反復執行了很多次這個命令才下載全了的.

2 安裝

cd ~/.vim/bundle/YouCompleteMe
./install.py --clang-completer  # 不需要sudo

成功的log如下:

3 設定

.vimrc中加入:

" YouCompleteMe
set runtimepath+=~/.vim/bundle/YouCompleteMe
let g:ycm_collect_identifiers_from_tags_files = 1           " 開啟 YCM 基於標籤引擎
let g:ycm_collect_identifiers_from_comments_and_strings = 1 " 注釋與字串中的內容也用於補全
let g:syntastic_ignore_files=[".*.py$"]
let g:ycm_seed_identifiers_with_syntax = 1                  " 語法關鍵字補全
let g:ycm_complete_in_comments = 1
let g:ycm_confirm_extra_conf = 0
let g:ycm_key_list_select_completion = ['<c-n>', '<Down>']  " 對映按鍵, 沒有這個會攔截掉tab, 導致其他外掛的tab不能用.
let g:ycm_key_list_previous_completion = ['<c-p>', '<Up>']
let g:ycm_complete_in_comments = 1                          " 在註釋輸入中也能補全
let g:ycm_complete_in_strings = 1                           " 在字串輸入中也能補全
let g:ycm_collect_identifiers_from_comments_and_strings = 1 " 注釋和字串中的文字也會被收入補全
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                           " 禁用語法檢查
inoremap <expr> <CR> pumvisible() ? "<C-y>" : "<CR>" |            " 回車即選中當前項
nnoremap <c-j> :YcmCompleter GoToDefinitionElseDeclaration<CR>|     " 跳轉到定義處
"let g:ycm_min_num_of_chars_for_completion=2                 " 從第2個鍵入字元就開始羅列匹配項

其中 ~/.vim/bundle/YouCompleteMe 為下載 YouCompleteMeu 的路徑.

4 使用

預設當鍵入兩個字母之後, 則啟動補全. 可以通過該變數調整: g:ycm_min_num_of_chars_for_completion
也可以使用原有的<c-x><c-o>來補全, ycm將其功能增強了.
按照本文設定, 可用<c-j>跳轉到定義處.
預設設定<TAB>會選擇補全內容, 本文的設定將其遮蔽了, 為了不會與snipmate等需要tab的衝突, 選擇補全改為了.
