vim安装YouCompleteMe 插件

 

 

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, required

filetype off                  " required



" set the runtime path to include Vundle and initialize

set 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, required

Plugin 'gmarik/vundle'



" The following are examples of different formats supported.

" Keep Plugin commands between here and filetype plugin indent on.

" scripts on GitHub repos

Plugin '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.html

Plugin 'L9'

Plugin 'FuzzyFinder'

Plugin 'file:///home/gmarik/path/to/plugin'

" ...



filetype plugin indent on     " required

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
