Question

I get a CSS file:

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;
}

I want to Alphabetize lines between the {…}

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;
}

I map F7 to do it

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

But I need to press F7 over and over again to get the work done.
If the CSS file is big, It’s time-consuming & easily get bored.
I want to get the cmds piped. So that, I only press F7 once!
Any idea? thanks!

Answer 1

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

Explanation:

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

You can of course map this to a keyboard shortcut or make it into a command:

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

" Or:

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

Then you can simply hit F7 or run:

:SortCSSBraceContents
