Vim自动补全神器–YouCompleteMe

1. 安装必要组件

sudo apt-get install libncurses5-dev libgnome2-dev libgnomeui-dev \

    libgtk2.0-dev libatk1.0-dev libbonoboui2-dev \

    libcairo2-dev libx11-dev libxpm-dev libxt-dev \

    python-dev ruby-dev mercurial checkinstall

2. 升级Vim 到7.4

手动添加PPA(Personal Package Archives)

sudo add-apt-repository ppa:nmi/vim-snapshots

sudo apt-get update

sudo apt-get install vim

3. 安装llvm & clang

到 http://llvm.org/releases/download.html#3.3 下载编译后的二进制文件
http://llvm.org/releases/3.3/clang+llvm-3.3-amd64-Ubuntu-12.04.2.tar.gz
解压到/

tar -zxf clang3.3-amd64-Ubuntu-12.04.2.tar.gz

cd clang+llvm-3.3-amd64-Ubuntu-12.04.2/

cp -r * /

或者sudo apt-get install clang3.3

如果在命令行输入clang,输出clang: error: no input files,说明安装成功

4. 下载 Vundle

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

Vundle可以让Vim自动从github等地方下载插件,而不用每次去vim.org上手动下载

修改.vimrc

set nocompatible              " be iMproved
set nu
set noswapfile
syntax on
set backspace=2
set tabstop=2
set shiftwidth=2
set completeopt=menu
:colorscheme ron
set cindent
set rtp+=~/.vim/bundle/vundle/
call vundle#rc()
Bundle 'gmarik/vundle'
Bundle 'Valloric/YouCompleteMe'
Bundle 'scrooloose/syntastic'
""""""""""syntastic""""""""""""
let g:syntastic_check_on_open = 1
let g:syntastic_cpp_include_dirs = ['/usr/include/']
let g:syntastic_cpp_remove_include_errors = 1
let g:syntastic_cpp_check_header = 1
let g:syntastic_cpp_compiler = 'clang++'
"set error or warning signs
let g:syntastic_error_symbol = 'x'
let g:syntastic_warning_symbol = '!'
"whether to show balloons
let g:syntastic_enable_balloons = 1

""""""""""""YCM""""""""""""""""""""
let g:ycm_global_ycm_extra_conf = '~/.vim/bundle/YouCompleteMe/cpp/ycm/.ycm_extra_conf.py'
let g:ycm_collect_identifiers_from_tags_files = 1
let g:ycm_seed_identifiers_with_syntax = 1
let g:ycm_confirm_extra_conf = 0

然后打开vim

在命令模式下输入

:BundleInstall,就会发现vim自动开始下载插件了

NOTE:

YouCompleteMe插件要下载很久,请稍安勿躁:-)

5. 编译ycm_core & ycm_support_libs

cd ~

mkdir ~/ycm_build

cd ~/ycm_build

cmake -G "Unix Makefiles"  ~/.vim/bundle/YouCompleteMe/cd ~

mkdir ~/ycm_build

cd ~/ycm_build

cmake -G "Unix Makefiles"  ~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp -DEXTERNAL_LIBCLANG_PATH=/lib/libclang.so

make ycm_core

make ycm_support_libs

这里要注意的是-DEXTERNAL_LIBCLANG_PATH这个参数，用于指定libclang.so的位置

6. 配置.ycm_extra_conf.py

~/.vim/bundle/YouCompleteMe/cpp/ycm/.ycm_extra_conf.py

在这个文件的flags尾部添加:

'-isystem',

'/usr/include',

'-isystem',

'/usr/include/c++/'

vim插件：显示树形目录插件NERDTree安装

wget http://www.vim.org/scripts/download_script.php?src_id=17123 -O nerdtree.zip
unzip nerdtree.zip

mkdir -p ~/.vim/{plugin,doc}

cp plugin/NERD_tree.vim ~/.vim/plugin/
cp doc/NERD_tree.txt ~/.vim/doc/

vim ~/.vimrc

然后添加

" NERDTree
map <F10> :NERDTreeToggle<CR>

taglist插件：

1.sudo apt-get install ctags
2.   taglist插件是以vim脚本的形式存在，因此只需要将其下载下来放到相应的目录即可。taglist基于ctags才能发挥作用，因此在使用taglist之前，确保已经安装了ctags。具体安装方法如下：
下载地址(两个可选择任意一个)：
Official site  http://vim-taglist.sourceforge.net/
VIM online  http://www.vim.org/scripts/script.php?script_id=273
下载解压后，将插件脚本文件(.vim)和帮助文件(.txt)分别放入vim常用目录：
$HOME/.vim/ 或
$HOME/vimfiles/ 或
$VIM/vimfiles/
下的
plugin/taglist.vim
doc/taglist.txt
中。
