193 | =head1 NAME | |
194 | ||
195 | App::MusicExpo - script which generates a HTML table of music tags | |
196 | ||
197 | =head1 SYNOPSIS | |
198 | ||
199 | use App::MusicExpo; | |
200 | App::MusicExpo->run; | |
201 | ||
202 | =head1 DESCRIPTION | |
203 | ||
204 | App::MusicExpo creates a HTML table from a list of songs. | |
205 | ||
206 | The default template looks like: | |
207 | ||
208 | | Title | Artist | Album | Genre | Track | Year | Type | | |
209 | |---------+---------+-----------------+---------+-------+------+------| | |
210 | | Cellule | Silence | L'autre endroit | Electro | 01/09 | 2005 | FLAC | | |
211 | ||
212 | where the type is a download link. If you have multiple files with the same | |
213 | basename (such as C<cellule.flac> and C<cellule.ogg>), they will be treated | |
214 | as two versions of the same file, so a row will be created with two download | |
215 | links, one for each format. | |
216 | ||
217 | =head1 OPTIONS | |
218 | ||
219 | =over | |
220 | ||
221 | =item B<--template> I<template> | |
222 | ||
223 | Path to the HTML::Template::Compiled template used for generating the music table. If '' (empty), uses the default format. Is empty by default. | |
224 | ||
225 | =item B<--prefix> I<prefix> | |
226 | ||
227 | Prefix for download links. Defaults to '/music/'. | |
228 | ||
229 | =item B<--cache> I<filename> | |
230 | ||
231 | Path to the cache file. Created if it does not exist. If '' (empty), disables caching. Is empty by default. | |
