我在.
vimrc中有这个删除尾部空格：
function! RemoveTrailingWhitespace()
for lineno in range(a:firstline,a:lastline)
let line = getline(lineno)
let cleanLine = substitute(line,'\(\s\|\)\+$','','e')
call setline(lineno,cleanLine)
endfor
endfunction
command -range RemoveTrailingWhitespace <line1>,<line2>call RemoveTrailingWhitespace()
command -range RT <line1>,<line2>call RemoveTrailingWhitespace()
这允许我调用：’<,'> RT来删除视觉上选定的行范围的尾随空格.当我只调用：RT时,它只在当前行上运行.我想要的是将命令应用于整个缓冲区.怎么能实现这一目标？
如果不指定范围,则带有范围的命令将应用于当前行.如果要在整个缓冲区上执行此操作,请使用：％RT或：1,$RT
原文链接：https://www.f2er.com/bash/384202.html将整个缓冲区作为默认范围可以做的是：
command -range=% RT <line1>,<line2>call RemoveTrailingWhitespace()
详情：
:h command-range
然后你看到：
Possible attributes are:
-range Range allowed,default is current line
-range=% Range allowed,default is whole file (1,$)
-range=N A count (default N) which is specified in the line
number position (like |:split|); allows for zero line
number.
-count=N A count (default N) which is specified either in the line
number position,or as an initial argument (like |:Next|).
Specifying -count (without a default) acts like -count=0
如果你有范围信息,为什么不在命令中调用vim-build：[range]来进行替换？那么你可以保存那些线getline,setline,也就是循环.
