This is a simple plugin to add ids to all headings, based on their text. It works as a postprocessing filter, allowing it to work on mdwn, wiki, html, rst and any other format that produces html. The code is available here:
#!/usr/bin/perl

package IkiWiki::Plugin::headinganchors;
use warnings;
use strict;
use IkiWiki 2.00;
sub import { #{{{
hook(type => "sanitize", id => "headinganchors", call => \&headinganchors);
} # }}}
sub text_to_anchor {
my $str = shift;
$str =~ s/^\s+//;
$str =~ s/\s+$//;
$str = lc($str);
$str =~ s/[&\?"\'\.,\(\)!]//mig;
$str =~ s/[^a-z]/_/mig;
return $str;
}
sub headinganchors (@) { #{{{
my %params=@_;
my $content=$params{content};
$content=~s{<h([0-9])>([^>]*)</h([0-9])>}{'<h'.$1.' id="'.text_to_anchor($2).'">'.$2.'</h'.$3.'>'}gie;
