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