打造linux下的source insight--YouCompleteMe安裝

1.安裝前準備

sudo apt-get install build-essential cmake

sudo apt-get install python-dev

sudo apt-get install git

2.Vundle的安裝

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

3.修改.vimrc檔案,以下是我的修改方案

runtime! debian.vim

"設定編碼

set encoding=utf-8

set fencs=utf-8,ucs-bom,shift-jis,gb18030,gbk,gb2312,cp936

set fileencodings=utf-8,ucs-bom,chinese

"語言設定

set langmenu=zh_CN.UTF-8

"顯示行号

set nu!

"設定文法高亮

syntax enable

syntax on

"設定配色方案

"colorscheme torte

"可以在buffer的任何地方使用滑鼠

set mouse=a

set selection=exclusive

set selectmode=mouse,key

"高亮顯示比對的括号

set showmatch

"去掉vi一緻性

set nocompatible

"設定縮進

set tabstop=4

set softtabstop=4

set shiftwidth=4

set autoindent

set cindent

if &term=="xterm"

    set t_Co=8

    set t_Sb=^[[4%dm

    set t_Sf=^[[3%dm

endif

set nocompatible

filetype off

set rtp+=~/.vim/bundle/Vundle.vim

call vundle#rc()

Bundle 'gmarik/vundle'

Bundle 'taglist.vim'

Bundle 'Valloric/YouCompleteMe'

Bundle 'Valloric/ListToggle'

Bundle 'scrooloose/syntastic'

filetype plugin indent on

""""""""""""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

"Settings for tagslist

let Tlist_Use_Right_Window = 1 "讓taglist視窗出現在Vim的右邊

let Tlist_File_Fold_Auto_Close = 1

"當同時顯示多個檔案中的tag時，設定為1，可使taglist隻顯示目前檔案tag，其它檔案的tag都被折疊起來。

let Tlist_Show_One_File = 1 "隻顯示一個檔案中的tag，預設為顯示多個

let Tlist_Sort_Type ='name' "Tag的排序規則，以名字排序。預設是以在檔案中出現的順序排序

let Tlist_GainFocus_On_ToggleOpen = 1 "Taglist視窗打開時，立刻切換為有焦點狀态

let Tlist_Exit_OnlyWindow = 1 "如果taglist視窗是最後一個視窗，則退出vim

let Tlist_WinWidth = 32 "設定窗體寬度為32，可以根據自己喜好設定

4.插件安裝

打開vim，并運作:PluginInstall

5.安裝YouCompleteMe插件

cd ~/.vim/bundle/YouCompleteMe/

./install.sh --clang-completer

6.如果~/.vim/bundle/YouCompleteMe/cpp/ycm/.ycm_extra_conf.py找不到檔案

需要自己建立目錄和相關檔案，.ycm_extra_conf.py如下

import os

import ycm_core

# These are the compilation flags that will be used in case there's no

# compilation database set (by default, one is not set).

# CHANGE THIS LIST OF FLAGS. YES, THIS IS THE DROID YOU HAVE BEEN LOOKING FOR.

# source code needs it.

# language to use when compiling headers. So it will guess. Badly. So C++

# headers will be compiled as C headers. You don't want that so ALWAYS specify

# a "-std=<something>".

# For a C project, you would set this to something like 'c99' instead of

# 'c++11'.

'-std=c++11',

# ...and the same thing goes for the magic -x option which specifies the

# language that the files to be compiled are written in. This is mostly

# relevant for c++ headers.

# For a C project, you would set this to 'c' instead of 'c++'.

'-x',

'c',

'-isystem',

'../BoostParts',

'-isystem',

# This path will only work on OS X, but extra paths that don't exist are not

# harmful

# Set this to the absolute path to the folder (NOT the file!) containing the

# compile_commands.json file to use that instead of 'flags'. See here for

# more details: http://clang.llvm.org/docs/JSONCompilationDatabase.html

#

# You can get CMake to generate this file for you by adding:

#   set( CMAKE_EXPORT_COMPILE_COMMANDS 1 )

# to your CMakeLists.txt file.

#

# Most projects will NOT need to set this to anything; you can just change the

# 'flags' list of compilation flags. Notice that YCM itself uses that approach.
