If you are not fimiliar with Vim, you can read this blog first: Getting Started with Vim by Vimtutor.

Install spf13-vim

spf13-vim is a distribution of vim plugins and resources for Vim, GVim and MacVim. We firstly install it as the basic IDE and then do some customizations:

$ sudo yum update
$ sudo yum install git
$ vim --version             # checkout >=7.4
$ curl http://j.mp/spf13-vim3 -L -o - | sh

Useful shortcuts:

• ctrl + e: open/close NERDTree left tool
• ctrl + p: search and open files
• m (inside NERDTree): Open NERDTree Menu
  • a: add file or folder

Customization

For customization, we can create three files:

~/.vimrc.local 
~/.vimrc.before.local  
~/.vimrc.bundles.local

Make tab equal to 2 spaces:

$ vim .vimrc.local
autocmd FileType * setlocal expandtab tabstop=2 shiftwidth=2 softtabstop=2

Select the language you want to support, it will install related plugins:

$ vim .vimrc.before.local    
let g:spf13_bundle_groups=['general', 'writing', 'youcompleteme', 'programming', 'scala', 'php', 'ruby', 'python', 'javascript', 'html', 'misc']
let g:spf13_no_autochdir = 1
let g:ycm_path_to_python_interpreter = '/usr/bin/python'

After configration, we need to run the following command inside vim:

$ vim
:BundleInstall

It will give WARN from youcompleteme plugin, you need to compile it by yourself in next step.

Compile youcompleteme

YouCompleteMe is a powerful code-completion engine for Vim:

$ sudo yum install automake gcc gcc-c++ kernel-devel cmake
$ sudo yum install python-devel python3-devel

# Compiling YCM with semantic support for C-family languages
$ cd ~/.vim/bundle/YouCompleteMe
$ ./install.py --clang-completer

After it completes, do BundleInstall again:

$ Vim

:BundleInstall
