Need some help: tag sorting

[yvi]

Since denise asked so nicely, I might put up some questions during the next few days.

I apologize if this description is messy - I can be very bad at explaining these things.

One of the bugs I am currently stuck on is http://bugs.dwscoalition.org/show_bug.cgi?id=2012 use a tag list not a tag cloud on the subscription filter interface The goal is to change th tag cloud here: http://www.dreamwidth.org/manage/subscriptions/filters to an alphabetically sorted tag list with usage numbers. Despite my complete inability with javaScript, I managed the 'tag list with usage numbers' part fine. I am, however, stuck on the alphabetically sorted part.

It looks like sorting the tags before they reach that point might be the way to go and htdocs/tools/endpoints/general.bml might be the key to that.

} elsif ( $mode eq 'list_tags' ) {
        $ret{tags} = LJ::Tags::get_usertags( $u, { remote => $remote } );

get_usertags returns a "Hashref; key being tag id, value being a large hashref". It looks like hashes in perl can be sorted - is there a way to sort this hash by name? I imagine this structure looks something like:

hash{id1} = { 'name' => name1,
'usage' => usage1,
...}
hash{id2} = { 'name' => name2,
'usage' => usage2,
...}

and now I need to sort the ids by name.

There is some sorting going on in cgi-bin/LJ/S2/TagPage.pm:

    my $tags = LJ::Tags::get_usertags($u, { remote => $remote });
    foreach my $kwid (keys %{$tags}) {
        # only show tags for display
        next unless $tags->{$kwid}->{display};
        push @taglist, LJ::S2::TagDetail($u, $kwid => $tags->{$kwid});
    }
    @taglist = sort { $a->{name} cmp $b->{name} } @taglist;

But that returns a sorted array.

Any ideas?

EDIT: Okay, looks like I either need to sort the ids by name and then return both the hashref and the array and handle that in the JavaScrript portion or sort in htdocs/js/subfilters.js itself. The relevant code is in function cfUpdateTags( data ), the for ( id in data.tags ) { loop would need to be run through in order of data.tags[id].name.

the end result of sorting a hash was not in fact a hash, but a sorted arrays of the keys.

A sorted list, strictly speaking.

But yes. Because you can't sort hashes - you sort the list of keys. (Either by the key themselves, or by something based on the key, depending on what you want to accomplish.)
