My text editors are especially configured for source code such as C/C++/shell editing. I prefer to use spaces instead of tab. And my favourite tab size is 4.

Some vimrc parameters and the comments are listed here. Details and the updated configuration files please refer to the git repository.

The .vimrc:

set number " show line number

set backup " keep a backup file
set backupdir=~/.vibackup " keep all backup files in one central dir
set backupcopy=yes

set tabstop=4
set shiftwidth=4
set expandtab

set autoindent " always set autoindenting on
set cindent " indent c code
syntax on

set incsearch " do incremental searching
set hlsearch " high light the search content

set history=50 " keep 50 lines of command line history
set ruler " show the cursor position all the time
set showcmd " display incomplete commands
