MP3::Tag::File(3pm)					User Contributed Perl Documentation				       MP3::Tag::File(3pm)

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 perl v5.14.2 2009-11-28 MP3::Tag::File(3pm)
