要安装YouCompleteMe ,vim须支持python。看是否支持,可以在vim中:version 查看, 如果python前有+号,就是支持,减号就是不支持。
如果不支持,需要以编译安装方式重新安装vim。
编译配置选项:
./configure --with-features=huge --enable-pythoninterp --enable-python3interp --enable-luainterp --enable-multibyte --enable-sniff --enable-fontset
在我的机器上装有python2.7.5 和 python3.3, 但加了enable-python3interp参数依然没有支持py3,不知何故,先不管,YouCompleteMe 只要求有py2.6以上。
安装vundle插件
git clone https://github.com/gmarik/vundle.git ~/.vim/bundle/vundle
在.vimrc中配置
set nocompatible " be iMproved, requiredfiletype off " required" set the runtime path to include Vundle and initializeset rtp+=~/.vim/bundle/vundle/call vundle#rc()" alternatively, pass a path where Vundle should install plugins"let path = '~/some/path/here'"call vundle#rc(path)" let Vundle manage Vundle, requiredPlugin 'gmarik/vundle'" The following are examples of different formats supported." Keep Plugin commands between here and filetype plugin indent on." scripts on GitHub reposPlugin 'tpope/vim-fugitive'Plugin 'Lokaltog/vim-easymotion'Plugin 'tpope/vim-rails.git'" The sparkup vim script is in a subdirectory of this repo called vim." Pass the path to set the runtimepath properly.Plugin 'rstacruz/sparkup', { 'rtp': 'vim/'}" scripts from http://vim-scripts.org/vim/scripts.htmlPlugin 'L9'Plugin 'FuzzyFinder'" scripts not on GitHubPlugin 'git://git.wincent.com/command-t.git'" git repos on your local machine (i.e. when working on your own plugin)Plugin 'file:///home/gmarik/path/to/plugin'" ...filetype plugin indent on " requiredBundle 'Valloric/YouCompleteMe'
保存退出,打开vim,输入 :BundleInstall 进行自动安装
进程如下,+号表示已经安装,>表示正在安装。

结束时有个错误,这是正常的,因为ycm需要手工编译出库文件
Done! With errors; press l to view log
ycm_client_support.[so|pyd|dll] and ycm_core.[so|pyd|dll] not detected; you need to compile YCM before using it. Read the docs!到 .vim/bundle/YouCompleteMe 下跑
./install.sh --clang-completer
参数是为了支持c/c++ 的补全。
安装完成后进行一些简单的配置就可以使用。
YouCompleteMe 的补全配置文件在/bundle/YouCompleteMe/cpp/ycm/.ycm_extra_conf.py,这是个隐藏文件。
默认会使用这个文件,也可以把这个文件copy到工程的根目录中作修改,打开工程文件时会优先使用当前目录下的配置文件。
如果找不到,会根据配置中的ycm_global_ycm_extra_conf 进行查找。
在.vimrc 中添加
let mapleader = "," " 这个leader就映射为逗号“,”
let g:ycm_global_ycm_extra_conf = '~/.vim/bundle/YouCompleteMe/cpp/ycm/.ycm_extra_conf.py' “配置默认的ycm_extra_conf.py
nnoremap <leader>jd :YcmCompleter GoToDefinitionElseDeclaration<CR> “按,jd 会跳转到定义let g:ycm_confirm_extra_conf=0 “打开vim时不再询问是否加载ycm_extra_conf.py配置let g:ycm_collect_identifiers_from_tag_files = 1 "使用ctags生成的tags文件
