=head1 NAME
Blosxom Plug-in: allmusic
=head1 SYNOPSIS
Displays a list of albums that link through to the appropriate allmusic.com page.
=head1 USAGE
Fill $album_file (by default "amg" in your blosxom dir) with a list of album codes from allmusic.com.
The required codes can be found by going to an album's page, and extracting the
"sql" variable from the URI. For example, for the the URI http://www.allmusic.com/cg/amg.dll?p=amg&uid=MISS70310181612&sql=A3krsa9ugu23k
add a line reading "A3krsa9ugu23k" to your $album_file. Add one code per line.
Alternatively, you can try inputting album titles. If the title corresponds to only one album, it'll probably work. If not, then it probably won\'t.
Prefix title searches with "T " and amg codes with "C ". You can include comments after a \"\#\". Thus your file might look like:
C A3krsa9ugu23k
C A3aq5g4sztv8z#helicopter helicopter
T the soft bulletin
In your template, add $allmusic::display to print the list of albums. The plugin
will display the corresponding album for each line in your $album_file. The
text descriptions can be styled in your stylesheet. They use class
"albumtitle" and "albumartist".
As this plugin uses some horrible hacks to parse the amg site, it may go wrong
on some albums. It may go wrong if AMG change their site. Any enhancements to my awful perl
will be greatfully accepted.
=head1 CONFIGURATION
Set $album_file to the location of the list of AMG codes.
Set $album_dir to a location where album info can be cached. Clear this out to
force the plugin to reparse the AMG site.
Set $imgsize to the height/width of the images. There is only one number, as I
think it is a good assumption that all album images are square.
=head1 BUGS
Probably lots! This is a first version, so it probably isn't very robust.
Please send any bug reports to bpb@lysozyme.net or as writebacks to my weblog:
