VIM的正则表达式

把行首的标号加1

%s/^[0-9]\+\./\=printf("%d\.",submatch(0)+1)/gc

 

从当前行开始

.,$s/^[0-9]\+\./\=printf("%d\.",submatch(0)+1)/gc

从当前行，每一行第一个

.,$s/[0-9]\+\./\=printf("%d\.",submatch(0)+1)/c

配合命令

/^[0-9]\.\+

函数

:nmap <F4> :call AddUnderline()<CR>:function AddUnderline():   let k = search('==\+\|--\+'):   if k > 0:       let chkType = getline(k):       call setpos('.',[0,(k-1),1,0]):       let col = virtcol("$"):       if chkType[0] == '=':           call setline(k, repeat('=', (col-1))):       elseif chkType[0] == '-':           call setline(k, repeat('-', (col-1))):       endif:       call setpos('.',[0,k,1,0]):   endif:endfunction
