223 | =head1 NAME | |
224 | ||
225 | App::MusicExpo - script which generates a HTML table of music tags | |
226 | ||
227 | =head1 SYNOPSIS | |
228 | ||
229 | use App::MusicExpo; | |
230 | App::MusicExpo->run; | |
231 | ||
232 | =head1 DESCRIPTION | |
233 | ||
234 | App::MusicExpo creates a HTML table from a list of songs. | |
235 | ||
236 | The default template looks like: | |
237 | ||
238 | | Title | Artist | Album | Genre | Track | Year | Type | | |
239 | |---------+---------+-----------------+---------+-------+------+------| | |
240 | | Cellule | Silence | L'autre endroit | Electro | 01/09 | 2005 | FLAC | | |
241 | ||
242 | where the type is a download link. If you have multiple files with the same | |
243 | basename (such as C<cellule.flac> and C<cellule.ogg>), they will be treated | |
244 | as two versions of the same file, so a row will be created with two download | |
245 | links, one for each format. | |
246 | ||
247 | =head1 OPTIONS | |
248 | ||
249 | =over | |
250 | ||
251 | =item B<--template> I<template> | |
252 | ||
253 | Path to the HTML::Template::Compiled template used for generating the music table. If '' (empty), uses the default format. Is empty by default. | |
254 | ||
255 | =item B<--prefix> I<prefix> | |
256 | ||
257 | Prefix for download links. Defaults to '/music/'. | |
258 | ||
259 | =item B<--cache> I<filename> | |
260 | ||
261 | Path to the cache file. Created if it does not exist. If '' (empty), disables caching. Is empty by default. | |
