DESCRIPTION

Extendable module for working with Music Tags. Music::Tag Is powered by various plugins that collect data about a song based on whatever information has already been discovered.

The motivation behind this was to provide a convenient method for fixing broken tags in music files. This developed into a universal interface to various music file tagging schemes and a convenient way to augment this from online databases.

Several plugin modules to find information about a music file and write it back into the tag are available. These modules will use available information (REQUIRED DATA VALUES and USED DATA VALUES) and set various data values back to the tag.

EXECUTABLE SCRIPT

An executable script, musictag is included. This script allows quick tagging of MP3 files and access to the plugins. To learn more, use:

musictag --help 
musictag --longhelp

METHODS

new()

Takes a filename, an optional hashref of options, and an optional first plugin and returns a new Music::Tag object. For example:

my $info = Music::Tag->new($filename, { quiet => 1 }, 'MP3' ) ;

If no plugin is listed, then it will automatically add the appropriate file plugin based on the extension. It does this by using the Music::Tag::Auto plugin. If no plugin is appropriate, it will return.

Options are global (apply to all plugins) and default (can be overridden by a plugin).

Plugin specific options can be applied here, if you wish. They will be ignored by plugins that don't know what to do with them. See the POD for each of the plugins for more details on options a particular plugin accepts.

Current global options include:

verbose

Default is false. Setting this to true causes plugin to generate a lot of noise.

quiet

Default is false. Setting this to true prevents the plugin from giving status messages. This default may be changed in the future, so always set it.

autoplugin

Option is a hash reference mapping file extensions to plugins. Technically, this option is for the Music::Tag::Auto plugin. Default is:

{   mp3   => 'MP3',
    m4a   => 'M4A',
    m4p   => 'M4A',
    mp4   => 'M4A',
    m4b   => 'M4A',
    '3gp' => 'M4A',
    ogg   => 'OGG',
    flac  => 'FLAC'   }

optionfile

Array reference of files to load options from. Default is:

[   '/etc/musictag.conf',   
    $ENV{HOME} . '/.musictag.conf'  ]

Note that this is only used if the 'load_options' method is called.

Option file is a pure perl config file using Config::Options.

ANSIColor

Default false. Set to true to enable color status messages.

LevenshteinXS

Default true. Set to true to use Text::LevenshteinXS to allow approximate matching with Amazon and MusicBrainz Plugins. Will reset to false if module is missing.

Levenshtein

Default true. Same as LevenshteinXS, but with Text::Levenshtein. Will not use if Text::Levenshtein can be loaded. Will reset to false if module is missing.

Unaccent

Default true. When true, allows accent-neutral matching with Text::Unaccent::PurePerl. Will reset to false if module is missing.

Inflect

Default false. When true, uses Lingua::EN::Inflect to perform approximate matches. Will reset to false if module is missing.

available_plugins()

Class method. Returns list of available plugins. For example:

foreach (Music::Tag->available_plugins) {
    if ($_ eq 'Amazon') {
        print "Amazon is available!\n";
        $info->add_plugin('Amazon', { locale => 'uk' });
    }
}

This method can also be used to check for a particular plugin, by passing an option. For example:

if (Music::Tag->avaialble_plugins('Amazon') {
    print "Amazon is available!\n";
    $info->add_plugin('Amazon', { locale => 'uk' });
}

default_options()

Class method. Returns default options as a Config::Options object.

LoadOptions()

Load options stated in optionfile from file. Default locations are /etc/musictag.conf and ~/.musictag.conf. Can be called as class method or object method. If called as a class method the default values for all future Music::Tag objects are changed.

add_plugin()

Takes a plugin name and optional set of options. Returns reference to a new plugin object. For example:

    my $plugin = $info->add_plugin('MusicBrainz', 
								   { preferred_country => 'UK' });

$options is a hashref that can be used to override the global options for a plugin.

First option can be a string such as "MP3" in which case Music::Tag::MP3->new($self, $options) is called, an object name such as "Music::Tag::Custom::MyPlugin" in which case Music::Tag::MP3->new($self, $options) is called, or an object, which is added to the list.

Current plugins include MP3, OGG, FLAC, M4A, Amazon, File, MusicBrainz, and LyricsFetcher.

Additional plugins can be created and may be available on CPAN. See Music::Tag::Generic for base class for plugins.

Options can also be included in the string, as in Amazon;locale=us;trust_title=1. This was added to make calling from musictag easier.

plugin()

my $plugin = $item->plugin('MP3')->strip_tag();

The plugin method takes a regular expression as a string value and returns the first plugin whose package name matches the regular expression. Used to access package methods directly. Please see "PLUGINS" section for more details on standard plugin methods.

get_tag()

get_tag applies all active plugins to the current Music::Tag object in the order that the plugin was added. Specifically, it runs through the list of plugins and performs the get_tag() method on each. For example:

$info->get_tag();

set_tag()

set_tag writes info back to disk for all Music::Tag plugins, or submits info if appropriate. Specifically, it runs through the list of plugins and performs the set_tag() method on each. For example:

$info->set_tag();

strip_tag()

strip_tag removes info from on disc tag for all plugins. Specifically, it performs the strip_tag method on all plugins in the order added. For example:

$info->strip_tag();

close()

Closes active filehandles on all plugins. Should be called before object destroyed or frozen. For example:

$info->close();

changed()

Returns true if changed. Optional value $new sets changed set to True of $new is true. A "change" is any data-value additions or changes done by MusicBrainz, Amazon, File, or Lyrics plugins. For example:

# Check if there is a change:
$ischanged = $info->changed();

# Force there to be a change
$info->changed(1);

data()

Returns a reference to the hash which stores all data about a track and optionally sets it. This is useful if you want to freeze and recreate a track, or use a shared data object in a threaded environment. For example;

use Data::Dumper;
my $bighash = $info->data();
print Dumper($bighash);

Please note that some values, specifically date values, will be objects.

options()

This method is used to access or change the options. When called with no options, returns a reference to the options hash. When called with one string option returns the value for that key. When called with one hash value, merges hash with current options. When called with 2 options, the first is a key and the second is a value and the key gets set to the value. This method is for global options. For example:

# Get value for "verbose" option
my $verbose = $info->options('verbose');

# or...
my $verbose = $info->options->{verbose};

# Set value for "verbose" option
$info->options('verbose', 0);

# or...
$info->options->{verbose} = 0;

setfileinfo

Sets the mtime and bytes attributes for you from filename. This may be moved to the File plugin in the future.

sha1()

Returns a sha1 digest of the file size in little endian then the first 16K of the music file. Should be fairly unique.

datamethods()

Returns an array reference of all data methods supported. Optionally takes a method which is added. Data methods should be all lower case and not conflict with existing methods. Data method additions are global, and not tied to an object. Array reference should be considered read only. For example:

# Print supported data methods:
my $all_methods = Music::Tag->datamethods();
foreach (@{$all_methods}) {
    print '$info->'. $_ . " is supported\n";
}

# Add is_hairband data method:
Music::Tag->datamethods('is_hairband');

used_datamethods()

Returns an array reference of all data methods that have values set. For example:

my $info = Music::Tag->new($filename);
$info->get_tag();
foreach (@{$info->used_datamethods}) {
    print $_ , ': ', $info->$_, "\n";
}

wav_out($fh)

Pipes audio data as a wav file to filehandle $fh. Returns true on success, false on failure, undefined if no plugin supports this.

This is currently experimental.

Data Access Methods

These methods are used to access the Music::Tag data values. Not all methods are supported by all plugins. In fact, no single plugin supports all methods (yet). Each of these is an accessor function. If you pass it a value, it will set the variable. It always returns the value of the variable.

There are three distinct ways of calling these methods: Traditional, PBP, and using the "get_data", "set_data", and "has_data" methods.

Damian Conway in his book "Perl Best Practices" states that data access methods should be called with separate methods for getting and setting values. This can be configured by passing pbp => 1 to the use option, e.g.

use Music::Tag ( pbp => 1 );

Once set, data can be accessed by adding get_ as a suffix to the method, written to by adding set__ as a suffix, and checked by adding has_ as a suffix. For example:

  use Music::Tag ( pbp => 1 );

  use feature qw(say);

  my $info = Music::Tag->new($filename);
 
  # Read basic info

  $info->get_tag();

  if ($info->has_artist()) {
      say 'Performer is ', $info->get_artist();
  }
 
  $info->set_artist('Throwing Muses');

  if ($info->has_artist()) {
      say 'Performer is now: ', $info->get_artist();
      # Will print 'Throwing Muses'
  }

  $info->set_tag();
  $info->close();

To force Traditional, add traditional => 1 as an option, e.g.

use Music::Tag (traditional => 1);

You can have pbp and traditional set to get both, if you want. Please note that calling it more than once in the same program, or set of programs, will have the affect of reading the methods. For example

use Music::Tag (traditional => 1);
use Music::Tag (pbp => 1);

# is the same as

use Music::Tag (traditional =>1, pbp=>1)

When using the traditional methods, an undefined function will return undef. This means that in list context, it will be true even when empty. This also means that the following code works:

my %important = (
	artist		=> $info->artist,
	album		=> $info->album,
	filename	=> $info->filename,
);

The best way to determine if a method is defined, is to use the predicate method (e.g. has_album). This is defined if either traditional or pbp is set to true.

The final way to access data is to use the "get_data", "set_data", and "has_data" methods. These will work even if pbp and traditional are both set to 0. This is how plugins should access data methods.

   'Description'   => A short description of the picture
   '_Data'         => The binary data for the picture.
   'filename'      => A filename for the picture.  Data overrides '_Data' and will
                      be returned as _Data if queried.  Filename is calculated as relative
                      to the path of the music file as stated in 'filename' or root if no
                      filename for music file available.
}

Note hashref MAY be generated each call. Do not modify and assume data-value in object will be modified! Passing a value will modify the data-value as expected. In other words:

# This works:
$info->picture( { filename => 'cover.jpg' } ) ;

# This may not:
my $pic = $info->picture;
$pic->{filename} = 'back_cover.jpg';

picture_filename, get_picture_filename, set_picture_filename, has_picture_filename

The recorddate in seconds since epoch. See notes in releaseepoch for format.

recordtime, get_recordtime, set_recordtime, has_recordtime

The time and date track was recoded. See notes in releasetime for format.

releasedate, get_releasedate, set_releasedate, has_releasedate

The release date in the form YYYY-MM-DD. The day or month values may be left off. Please keep this in mind if you are parsing this data.

Because of bugs in my own code, I have added 2 sanity checks. Will not set the time and return if either of the following are true:

1) Time is set as 0000-00-00
2) Time is set as 1900-00-00

All times should be GMT.

releasedt, get_releasedt, set_releasedt, has_releasedt

The DateTime object used internally.

releaseepoch, get_releaseepoch, set_releaseepoch, has_releaseepoch

The release date of an album in terms "UNIX time", or seconds since the SYSTEM epoch (usually Midnight, January 1, 1970 GMT). This can be negative or > 32 bits, so please use caution before assuming this value is a valid UNIX date. This value will update releasedate and vice-versa. Since this accurate to the second and releasedate only to the day, setting releasedate will always set this to 12:00 PM GMT the same day.

Please note that this has some limitations. In 32bit Linux, the only supported dates are Dec 1901 to Jan 2038. In windows, dates before 1970 will not work. Refer to the docs for Time::Local for more details.

releasetime, get_releasetime, set_releasetime, has_releasetime

Like releasedate, but adds the time. Format should be YYYY-MM-DD HH::MM::SS. Like releasedate, all entries but year are optional.

All times should be GMT.

secs, get_secs, set_secs, has_secs

The number of seconds in the recording.

title, get_title, set_title, has_title

The name of the song.

totaldiscs, get_totaldiscs, set_totaldiscs, has_totaldiscs

The total number of discs, if a multi volume set.

totaltracks, get_totaltracks, set_totaltracks, has_totaltracks

The total number of tracks on the album.

track, get_track, set_track, has_track

The track number

tracktags, get_tracktags, set_tracktags, has_tracktags

A array reference or comma separated list of tags in plain text for the track.

tracknum, get_tracknum, set_tracknum, has_tracknum

The track number and optionally the total number of tracks, separated by a slash. Setting it sets the track and totaltracks values (and vice-versa).

upc, get_upc, set_upc, has_upc

The Universal Product Code on the package of a product. Returns same value as ean without initial 0 if ean has an initial 0. If set and ean is not set, sets ean and adds initial 0. It is possible for ean and upc to be different if ean does not have an initial 0.

url, get_url, set_url, has_url

A URL associated with the track (often a link to the details page on Amazon).

year, get_year, set_year, has_year

The year a track was released. Returns year set in releasedate if available. Does not set releasedate.

Non Standard Data Access Methods

These methods are not currently used by any standard plugin. They may be used in the future, or by other plugins (such as a SQL plugin). Included here to standardize expansion methods.

albumid, artistid, songid, get_albumid, get_artistid, get_songid, set_albumid, set_artistid, set_songid, has_albumid, has_artistid, has_songid: These three values can be used by a database plugin. They should be GUIDs like the MusicBrainz IDs. I recommend using the same value as mb_albumid, mb_artistid, and mb_trackid by default when possible.
ipod, ipod_dbid, ipod_location, ipod_trackid, get_ipod, get_ipod_dbid, get_ipod_location, get_ipod_trackid, set_ipod, set_ipod_dbid, set_ipod_location, set_ipod_trackid, has_ipod, has_ipod_dbid, has_ipod_location, has_ipod_trackid: Suggested values for an iPod plugin.
user, get_user, set_user, has_user: Used for user data. Reserved. Please do not use this in any Music::Tag plugin published on CPAN.

MP3 File information

frequency, get_frequency, set_frequency, has_frequency: The frequency of the recording (in Hz).
frames, get_frames, set_frames, has_frames: Number of frames for an MP3 file.
framesize, get_framesize, set_framesize, has_framesize: Average framesize for an MP3 file.
path, get_path, set_path, has_path: Path of file, but not set by filename so could be used for a relative path.
stereo, get_stereo, set_stereo, has_stereo: File is stereo.
vbr, get_vbr, set_vbr, has_vbr: File has a variable bitrate.
pregap, postgap, gaplessdata, samplecount, appleid, get_pregap, get_postgap, get_gaplessdata, get_samplecount, get_appleid, set_pregap, set_postgap, set_gaplessdata, set_samplecount, set_appleid, has_pregap, has_postgap, has_gaplessdata, has_samplecount, has_appleid: Used to store gapless data. Some of this is supported by Music::Tag::MP3 as an optional value requiring a patched MP3::Info.
codec, get_codec, set_codec, has_codec: Codec used for encoding file

Semi-internal methods for use by plugins.

status

Semi-internal method for printing status.

error

Semi-internal method for printing errors.

get_data()

Calls the data access method for an attribute. This is the recommended way to access data from a plugin, as the user may have elected to have PBP attribute methods, or not...

Example:

# Get the album artist
$info->get_data('albumartist');

set_data()

Calls the data writer method for an attribute.

Example:

# Set the album artist
$info->set_data('albumartist','Sarah Slean');

has_data()

Calls the data predicate method for an attribute.

Example:

# Does it have an album artist?
if ( not $info->has_data('albumartist')) {
    $info->set_data('albumartist','Sarah Slean');
}

PLUGINS

See Music::Tag::Generic for base class for plugins.

BUGS

No method for evaluating an album as a whole, only track-by-track method. Several plugins do not support all data values. Has not been tested in a threaded environment.
