NAME ^

MP3::Tag::File - Module for reading / writing files

SYNOPSIS ^

  my $mp3 = MP3::Tag->new($filename);

  ($title, $artist, $no, $album, $year) = $mp3->parse_filename();

see MP3::Tag

DESCRIPTION ^

MP3::Tag::File is designed to be called from the MP3::Tag module.

It offers possibilities to read/write data from files via read(), write(), truncate(), seek(), tell(), open(), close(); one can find the filename via the filename() method.

parse_filename()
  ($title, $artist, $no, $album, $year) = $mp3->parse_filename($what, $filename);

parse_filename() tries to extract information about artist, title, track number, album and year from the filename. (For backward compatibility it may be also called by deprecated name read_filename().)

This is likely to fail for a lot of filenames, especially the album will be often wrongly guessed, as the name of the parent directory is taken as album name.

$what and $filename are optional. $what maybe title, track, artist, album or year. If $what is defined parse_filename() will return only this element.

If $filename is defined this filename will be used and not the real filename which was set by MP3::Tag with MP3::Tag->new($filename). Otherwise the actual filename is used (subject to configuration variable decode_encoding_filename).

Following formats will be hopefully recognized:

- album name/artist name - song name.mp3

- album_name/artist_name-song_name.mp3

- album.name/artist.name_song.name.mp3

- album name/(artist name) song name.mp3

- album name/01. artist name - song name.mp3

- album name/artist name - 01 - song.name.mp3

If artist or title end in (NUMBER) with 4-digit NUMBER, it is considered the year.

title()
 $title = $mp3->title($filename);

Returns the title, guessed from the filename. See also parse_filename(). (For backward compatibility, can be called by deprecated name song().)

$filename is optional and will be used instead of the real filename if defined.

artist()
 $artist = $mp3->artist($filename);

Returns the artist name, guessed from the filename. See also parse_filename()

$filename is optional and will be used instead of the real filename if defined.

track()
 $track = $mp3->track($filename);

Returns the track number, guessed from the filename. See also parse_filename()

$filename is optional and will be used instead of the real filename if defined.

year()
 $year = $mp3->year($filename);

Returns the year, guessed from the filename. See also parse_filename()

$filename is optional and will be used instead of the real filename if defined.

album()
 $album = $mp3->album($filename);

Returns the album name, guessed from the filename. See also parse_filename() The album name is guessed from the parent directory, so it is very likely to fail.

$filename is optional and will be used instead of the real filename if defined.

comment()
 $comment = $mp3->comment($filename);   # Always undef
genre()
 $genre = $mp3->genre($filename);       # Always undef
