如何在Vim中对CSS文件进行字母排序

我得到一个CSS文件：

div#header h1 {
    z-index: 101;
    color: #000;
    position: relative;
    line-height: 24px;
    margin-right: 48px;
    border-bottom: 1px solid #dedede;
    font-size: 18px;
}

div#header h2 {
    z-index: 101;
    color: #000;
    position: relative;
    line-height: 24px;
    margin-right: 48px;
    border-bottom: 1px solid #dedede;
    font-size: 18px;
}

我想要将{…}

div#header h1 {
    border-bottom: 1px solid #dedede;
    color: #000;
    font-size: 18px;
    line-height: 24px;
    margin-right: 48px;
    position: relative;
    z-index: 101;
}

div#header h2 {
    border-bottom: 1px solid #dedede;
    color: #000;
    font-size: 18px;
    line-height: 24px;
    margin-right: 48px;
    position: relative;
    z-index: 101;
}

我映射F7来做

nmap <F7> /{/+1<CR>vi{:sort<CR>

但是我需要一次又一次地按F7来完成工作。
如果CSS文件很大，这是耗时的很容易觉得无聊。
我想得到cmds管道。所以，我只按F7一次！
任何想法？谢谢！

:g#\({\n\)\@<=#.,/}/sort

说明：

g        " Work over the whole file running .,/}/sort on each line that matches
         " the pattern \({\n\)\@<=
#...#... " Delimiters: first bit is search pattern,second bit is what
         " to do on each matching line
\(       " Grouping,containing:
  {\n    " Open brace followed by new line
\)       " End of grouping
\@<=     " Negative look-behind,so match after the new-line,but make sure that
         " the match point is preceded by an open brace and a new-line

.,/}/    " From this line to the next closing brace...
sort     " Sort the lines

您当然可以将其映射到键盘快捷方式或将其转换为命令：

:nmap <F7> :g#\({\n\)\@<=#.,/}/sort<CR>

" Or:

:command! SortCSSBraceContents :g#\({\n\)\@<=#.,/}/sort

那么你可以简单地点击F7或运行：

:SortCSSBraceContents
