我的.vimrc配置

termux平台下，通过pkg update && pkg upgrade && pkg install vim来获得vim。可是，当我配置.vimrc时发现如果我每在一个平台使用vim都要敲键盘的话，太浪费时间了。毕竟，人生苦短。于是，我将win10、centos平台下编写的配置写下来；以后就复制粘贴就行了。
在Windows平台下，Full安装默认出现：

source $VIMRUNTIME/vimrc_example.vim

set diffexpr=MyDiff()
function MyDiff()
  let opt = '-a --binary '
  if &diffopt =~ 'icase' | let opt = opt . '-i ' | endif
  if &diffopt =~ 'iwhite' | let opt = opt . '-b ' | endif
  let arg1 = v:fname_in
  if arg1 =~ ' ' | let arg1 = '"' . arg1 . '"' | endif
  let arg1 = substitute(arg1, '!', '!', 'g')
  let arg2 = v:fname_new
  if arg2 =~ ' ' | let arg2 = '"' . arg2 . '"' | endif
  let arg2 = substitute(arg2, '!', '!', 'g')
  let arg3 = v:fname_out
  if arg3 =~ ' ' | let arg3 = '"' . arg3 . '"' | endif
  let arg3 = substitute(arg3, '!', '!', 'g')
  if $VIMRUNTIME =~ ' '
    if &sh =~ '<cmd'
      if empty(&shellxquote)
        let l:shxq_sav = ''
        set shellxquote&
      endif
      let cmd = '"' . $VIMRUNTIME . 'diff"'
    else
      let cmd = substitute($VIMRUNTIME, ' ', '" ', '') . 'diff"'
    endif
  else
    let cmd = $VIMRUNTIME . 'diff'
  endif
  let cmd = substitute(cmd, '!', '!', 'g')
  silent execute '!' . cmd . ' ' . opt . arg1 . ' ' . arg2 . ' > ' . arg3
  if exists('l:shxq_sav')
    let &shellxquote=l:shxq_sav
  endif
endfunction

在linux平台下：

写完配置文件后，就要git了：

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

随后进入 vim:
执行：
PluginInstall

git相关知识，再次写一下：
