152 | =head1 NAME | |
153 | ||
154 | App::MusicExpo - script which generates a HTML table of music tags | |
155 | ||
156 | =head1 SYNOPSIS | |
157 | ||
158 | use App::MusicExpo; | |
159 | App::MusicExpo->run; | |
160 | ||
161 | =head1 DESCRIPTION | |
162 | ||
163 | App::MusicExpo creates a HTML table from a list of songs. | |
164 | ||
165 | The default template looks like: | |
166 | ||
167 | | Title | Artist | Album | Genre | Track | Year | Type | | |
168 | |---------+---------+-----------------+---------+-------+------+------| | |
169 | | Cellule | Silence | L'autre endroit | Electro | 01/09 | 2005 | FLAC | | |
170 | ||
171 | where the type is a download link. If you have multiple files with the same | |
172 | basename (such as C<cellule.flac> and C<cellule.ogg>), they will be treated | |
173 | as two versions of the same file, so a row will be created with two download | |
174 | links, one for each format. | |
175 | ||
176 | =head1 OPTIONS | |
177 | ||
178 | =over | |
179 | ||
180 | =item B<--template> I<template> | |
181 | ||
182 | Path to the HTML::Template::Compiled template used for generating the music table. If '' (empty), uses the default format. Is empty by default. | |
183 | ||
184 | =item B<--prefix> I<prefix> | |
185 | ||
186 | Prefix for download links. Defaults to '/music/'. | |
187 | ||
188 | =item B<--cache> I<filename> | |
189 | ||
190 | Path to the cache file. Created if it does not exist. If '' (empty), disables caching. Is empty by default. | |
