vim复制代码包含注释时格式会乱掉(转)

乱码问题
一般来说只需要正确设置vim的编码识别序列就很少会遇到乱码问题：
set fileencodings=ucs-bom,utf-8,utf-16,gbk,big5,gb18030,latin1

每次复制代码时，如果代码里有 // 这样的注释就容易让格式乱掉，通过下面的设置就可以避免这种情况。

粘贴代码时取消自动缩进
VIM在粘贴代码时会自动缩进，把代码搞得一团糟糕，甚至可能因为某行的一个注释造成后面的代码全部被注释掉，我知道有同学这个时候会用vi去打开文件再粘贴上去（鄙人以前就是这样），其实需要先设置一下
set paste
然后再进入插入模式粘贴，代码就不会被自动缩进。可是敲代码的时候需要自动缩进，又得改回来:
set nopaste
最方便的方法就是在.vimrc中加一句：
set pastetoggle=<F9>
以后在插入模式下，只要按F9键就可以切换自动缩进。
