在用户自己的目录下有个.vimrc就是vim的配置文件，在这里可以随时添加扩展
我一直使用的配置如下,在win下也可使用：
set nobomb
set fileencodings=utf-8,gb2312,gbk,gb18030
set termencoding=utf-8
set encoding=utf-8
set fileformats=unix
set softtabstop=4
set expandtab
set shiftwidth=4
set guifont=15
set nocompatible " Use Vim defaults (much better!)
set bs=indent,eol,start " allow backspacing over everything in insert mode
"set ai " always set autoindenting on
"set backup " keep a backup file
set viminfo='20,"50 " read/write a .viminfo file, don't store more
" than 50 lines of registers
set history=50 " keep 50 lines of
" command line history
set ruler " show the cursor position all the time
" Only do this part when compiled with support for autocommands
if has("autocmd")
augroup redhat
autocmd!
" In text files, always limit the width of text to 78 characters
autocmd BufRead *.txt set tw=78
" When editing a file, always jump to the last cursor position
autocmd BufReadPost *
if line("'"") > 0 && line ("'"") <= line("$") |
exe "normal! g'"" |
endif
" don't write swapfile on most commonly used directories for NFS mounts or USB sticks
autocmd BufNewFile,BufReadPre /media/*,/mnt/* set directory=~/tmp,/var/tmp,/tmp
" start with spec file template
autocmd BufNewFile *.spec 0r /usr/share/vim/vimfiles/template.spec
augroup END
endif
if has("cscope") && filereadable("/usr/bin/cscope")
set csprg=/usr/bin/cscope
set csto=0
set cst
set nocsverb
" add any database in current directory
if filereadable("cscope.out")
cs add cscope.out
" else add database pointed to by environment
elseif $CSCOPE_DB != ""
cs add $CSCOPE_DB
endif
set csverb
endif
" Switch syntax highlighting on, when the terminal has colors
" Also switch on highlighting the last used search pattern.
if &t_Co > 2 || has("gui_running")
syntax on
set hlsearch
set cursorline
hi cursorline guibg=#333333
hi CursorColumn guibg=#333333
endif
filetype plugin on
if &term=="xterm"
set t_Co=8
set t_Sb=^[[4%dm
set t_Sf=^[[3%dm
endif
" Don't wake up system with blinking cursor:
