Sort Markdown file by headings

Sort Markdown file by headings

[Guido Milanese]

[-- Attachment #1.1: Type: text/plain, Size: 1377 bytes --]

I was wondering if it is possible to sort a whole markdown file using 
headings as keys for sorting, and I found two onle-line scripts, the former 
in Perl and the latter in (g)awk (see 
http://stackoverflow.com/questions/25351917/sort-markdown-file-by-heading).

They are easy to manage (the Perl script seems to me to be a little better) 
but limited to the first heading level. For my person use I wrote a script 
that supports 2 levels (could be easily adapted to a 3rd level, however). I 
would like to know if the script looks useful to others: if so, I will 
clean the code, write a short documentation and publish it. The script 
assumes a markdown headings syntax using '#' , not  '====='  , but can be 
adapted if requested.

Thanks for this great group, I am learning a lot.

It certainly sounds useful but it is hard to tell without looking at the
code or some documentation. I'm happy to have a look at the code if you
post it to a pastebin like gist for example.

One way might be to use the Voom outliner plugin for Vim, which understands
Markdown and sort the headings manually in the outline pane if there are
not too many. Too bad that sorting non-ASCII letters correctly using Lua
probably is a pain if possible at all, or one could sort the output of the
`make_sections` function inside a filter.

Someone helped me to make a proper script which will handle 3 levels:


#!/usr/bin/env perl

local $/;
my $text = <>;
my ($start, @chapters) = split/^#(?=[^#])/m, $text;
print $start;
for (sort @chapters) {
    my ($level1, @subchapters) = split/^##(?=[^#])/m;
    print "#$level1";
        for (sort @subchapters) {
        my ($level2, @subsubchapters) = split/^###(?=[^#])/m;
        print "##$level2";
        print map {"###$_"} sort @subsubchapters; 
        }
}
