NAME

mp3lintrc - configuration file for mp3lint

CONTENTS

SYNOPSIS

/etc/mp3lintrc, $HOME/.mp3lintrc

DESCRIPTION

mp3lint can be configured using the file .mp3lintrc in your home directory.

The config file .mp3lintrc is actually a fragment of perl, so you can put any valid perl code in there. Don’t worry if you don’t know perl, you don’t need to write any actual code. The best thing to do is work your way through, altering the existing statements. Make sure every (non-blank) line ends with a semicolon (;).

.mp3lintrc is automatically created the first time you run mp3lint.

If you use MP3::Archive(3) with any other tool than mp3lint, eg some of the tools in mp3-archive-tools(1), you will have a configuration in .mp3archiverc that you may wish to share with mp3lint. To do this, either delete the non mp3lint-specific parts of .mp3lintrc (the first half, up to the comment about mp3lint) and replace them with:



 require "$ENV{HOME}/.mp3archiverc"



or do it the other way round, and replace all the contents of .mp3archiverc with:



 require "$ENV{HOME}/.mp3lintrc";



MP3::Archive will ignore any variables it doesn’t know about. For more details, see MP3::Archive::Config(3).

FORMATS

Formats are used to define valid filenames and to specify where the artistname, albumname, etc are located.

Formats are regular expressions (see perlretut(1) and perlre(1)), but with ARTIST, ALBUM, TRACK, TRKNUM and EXT as placeholders for the artist, album, track name (song title), track number and file extension respectively.

If you don’t know about regular expressions, don’t worry, treat them like regular strings, but put a backslash (\) before any characters other than letters, numbers and spaces (especially forward slash (/) and period (.)).

There are two types of formats.

Variables beginning with $formats_ are lists of permissible formats for parsing a filename, each of which are regular expressions (see perlretut(1) and perlre(1) for details). The formats are references to arrays, which essentially you can have as many as you want, separated by commas, and they must start and end with [ and ] respectively. The individual formats should be quoted with single quotes ().

Variables beginning with $format_ are single formats that are ordinary strings, not regular expressions, and are used when creating filenames. They don’t have [ and ] round them, but still should be quoted with single quotes (), and there should be only one of them, not a list.

    Examples

These are from the default setup.



 $formats_album=[TRKNUM - ARTIST - ALBUM - TRACK\.EXT,
                 ARTIST - ALBUM - TRKNUM - TRACK\.EXT];



This defines two acceptable formats for album tracks. The first one would match eg:



 01 - Talk Talk - Spirit Of Eden - The Rainbow.mp3



and the second one would match eg:



 DJ Shadow - Endtroducing - 07 - Stem-Long Stem.mp3

 $formats_track=[ARTIST - TRACK\.EXT];



This defines one acceptable format for non-album tracks. This would match eg:



 Radiohead - Paranoid Android (Live at the 10 Spot).ogg

 $format_write_album=TRKNUM - ARTIST - ALBUM - TRACK.EXT;



This can be though of as the reverse of $formats_album. It defines the format to be used when creating a file, so in this example, given TRKNUM 02, ARTIST Dead Can Dance, ALBUM Aion, TRACK Saltarello, and EXT wav, it would produce the filename:



 02 - Dead Can Dance - Aion - Saltarello.wav



CONFIGURATION VARIABLES

Start with the default .mp3lintrc, which will be created for you when you run mp3lint. Work your way through top to bottom. The file is parsed as perl code, but you should be able to get by without knowing any perl. Lines which start with # are comments, and can be ignored. Non-blank lines should end with ;. The last line of the file should be 1;
$formats_album This specifies acceptable formats for album tracks.

Default:



 $formats_album= [TRKNUM - ARTIST - ALBUM - TRACK\.EXT>, ARTIST - ALBUM - TRKNUM - TRACK\.EXT];



See FORMATS for details.

$formats_track This specifies acceptable formats for non-album tracks.

Default:



 $formats_track=[ARTIST - TRACK\.EXT];



See FORMATS for details.

$formats_album_dir This specifies how to extract info from the directory of an album track.

Default:



 $formats_album_dir= [ARTIST - ALBUM$,ARTIST\/ALBUM$];



This would match



 Spiritualised - Lazer Guided Melodies



or



 Spiritualised/Pure Phase



both at the end of the pathname (The $ means match the end of the line).

$formats_track_dir This specifies how to extract info from the directory of a non-album track.

Default:



 $formats_track_dir= [ARTIST$];



This specifies the last portion of the pathname is the artist.

$formats_album_m3u, $formats_track_m3u Specifies the format of m3u playlist filenames for album and non-album tracks.

Default:



 $formats_album_m3u= [ARTIST - ALBUM\.EXT];

 $formats_track_m3u = [ARTIST\.EXT];



$format_default This is how to treat files that aren’t in any of the defined pathnames (see $paths_track and $paths_album below). It can be either album, to treat them as album tracks, track to treat them as non-album tracks, or anything else (eg skip) to ignore them.

Default:

$format_default=skip;

$format_delimiter_album, $format_delimiter_track These specify the delimiters for album and non-album tracks. This allows extra checks, eg to make sure there are the right number of fields (eg, if the delimiter is ‘-’ and you have a track named Stem - Long Stem, so the file is called



 07 - DJ Shadow - Entroducing - Stem - Long Stem.mp3



then the extra dash will cause you problems, but specifying a delimiter will allow mp3lint to determine there are too many fields.

Default:



 $format_delimiter_album=  - ;

 $format_delimiter_track=  - ;



$paths_album, $paths_track These are used to determine from its pathname whether a file should be treated as part of an album. They are regular expressions, so the same warnings about quoting apply as to formats. This also means that they are substring matches, so the defaults below match any pathname that contains a component containing album or track. Although there is only one path each in the default, they can be lists of multiple paths (or portions of paths) to match.

Default:



 $paths_album=[album];

 $paths_track=[track];



This means that any pathname containing album or track will be treated accordingly (eg /music/groovy-albums/).

$archive_root $archive_root is currently only used to define the $path_write_* variables (below), but its use may be expanded in the future.

Default:



 $archive_root="$ENV{HOME}/music";



On any sane unix system, $ENV{HOME} expands to your home directory.

$path_write_album, $path_write_track $path_write_album and $path_write_track are used to determine the canonical pathname for files, for tools like movemusic(1).

The defaults are defined relative to $archive_root (see above).

Defaults:



 $path_write_album="$archive_root/cut/albums/";
 $path_write_track="$archive_root/tracks/";



$format_write_album, $format_write_track, $format_write_album_m3u, $format_write_track_m3u, $format_write_album_dir, $format_write_track_dir These variables are analogous to the $formats_* variables above, but they are used for constructing filenames rather than parsing them to extract information. They are not regular expressions, they are ordinary strings, and there is only one of each rather than a list (array). The same magic variables (TRKNUM, ARTIST, ALBUM, TRACK) are used and are replaced with the actual data.

Defaults:



 $format_write_album=TRKNUM - ARTIST - ALBUM - TRACK.EXT;
 $format_write_track=ARTIST - TRACK.EXT;
 $format_write_album_m3u=ARTIST - ALBUM.EXT;
 $format_write_track_m3u=ARTIST.EXT;
 $format_write_album_dir="/ARTIST/ALBUM/";
 $format_write_track_dir="/ARTIST/";



Variables below this point are specific to mp3lint, not shared with MP3::Archive.

$lint_extensions These are the filename extensions mp3lint looks for. There is not much point adding entries without implementing corresponding tools, unless you have weird extensions for your files you want it to find, but if you wanted to completely ignore a certain type of file, you could remove it from the list.

Default:



 $lint_extensions= ["mp3","mp2","wav","ogg","m3u","flac","au"];



$lint_various If the pathname contains this, no warning is issued if the filename and directory name disagree on the artist. This allows for multi-artist compilations.

Default:



 $lint_various=\/Various\/;



$lint_fix Whether to attempt to fix problems as we find them. Currently only fixes permissions. This can also be enabled with the -f flag to mp3lint.

Default:



 $lint_fix=0;



ie no.

$lint_skip A series of regular expressions (see perlretut(1) and perlre(1)) of messages to skip printing. This can be used to permanently suppress messages you don’t want to see. For a more complex system of suppressing messages on a per-file basis, see mp3lintskip(1).

The default skip messages suppress the most pedantic of the error messages. To enable all messages, change the line in your .mp3lintrc that mentions $lint_skip to:



 $lint_skip=[];



Default:



 $lint_skip=["^filename:caps:", "^filename:the:", "^filename:disc:"];



$lint_case Controls filename capitalisation style (in filename:caps test).

This variable only applies if Text::Autoformat is installed.

Default:



 $lint_case="highlight";



Available values:
highlight Capitalises everything except unimportant words. This is the default.
title Capitalises every word.
sentence Capitalises the first word.
upper Uppercases everything.
lower Lowercases everything.

$lint_perms_file, $lint_perms_dir Specifies the correct permissions for files and directories. For more details, see the section in mp3lint-tools(1) on the tool filesys, test perms.

Default:



 $lint_perms_file=0644;

 $lint_perms_dir=0755;



The default allows any user to play your music, but only you to write to it.

$lint_minbitrate_mp3 Minimum bitrate for mp3 files. You may wish to allow a little leeway, to allow for VBR files that average just under the target. This is why the default is 120kbps not 128kbps.

Default:



 $lint_minbitrate_mp3=120;



$lint_minbitrate_ogg Minimum bitrate for ogg vorbis files. The default average bitrate of files created by oggenc is 110kbps, so we allow a leeway of 10kbps in the default.

Default:



 $lint_minbitrate_ogg=100;



$lint_minsamplerate The minimum sample rate in Hz. The default is 44100, which is CD quality.

Default:



 $lint_minsamplerate=44100;



$lint_minbitsize The minimum bit size of the sample. Most decent sounding samples are at least 16 bit.

Default:



 $lint_minbitsize=16;



$lint_allow_wav Whether to check wav files or just complain about their presence. This is useful if your only use for wav files is as part of the ripping process, so if mp3lint finds one it probably means your ripper died and left wavs lying about.

Default:



 $lint_allow_wav=1;



This means to check wav files as normal.

$lint_maxbadframes_mp3info, $lint_maxbadframes_mp3check Maximum bad frames accepted before we complain. May be useful because sometimes we get false errors from mp3info or mp3check due to iffy handling of ID3v2 tags. Different values can be set for mp3info and mp3check. The default allows no bad frames.

Default:



 $lint_maxbadframes_mp3check=0;

 $lint_maxbadframes_mp3info=0;



ENVIRONMENT

$MP3LINTRC If set, uses this instead of $HOME/.mp3lintrc
$HOME Used to find .mp3lintrc

BUGS

None known. Please report any found to ianb@nessie.mcc.ac.uk

I am especially interested in how well the code for filename formats works for other people’s filenames.
