NAME
Normalize::Text::Music_Fields - normalize names of people's and (musical) works.
SYNOPSIS
$name = $obj->Normalize::Text::Music_Fields::normalize_person($name);
$work = $obj->Normalize::Text::Music_Fields::normalize_piece($work);
# $obj should have methods `name_for_field_normalization', 'shorted_person'
DESCRIPTION
Databases of names and of works-per-name are taken from plain-text
files (optionally in mail-header format). Names are stored in *.lst files.
Works are stored in .comp files named after the shortened name
of the composer.
The directories of these files are looked in the environment variable
MUSIC_FIELDS_PATH (if defined, split the same way as PATH), or in
$ENV{HOME}/.music_fields, and - (and - is replaced by the directory
named as the module file with .pm dropped). At runtime, one can
replace the list by calling function Normalize::Text::Music_Fields::set_path()
with the list of directories as the argument.
(Since parsed files are cached, replacing the directory list should be done
as early as possible.)
Files may be managed with utility subroutines provided with the module:
# Translate from one-per-line to mail-header format:
perl -wple "BEGIN {print q(# format = mail-header)} s/#\s*normalized\s*$//; $_ = qq(Title: $_) unless /^\s*(#|$)/; $_ = qq(\n$_) if $p and not /^##/; $_ .= qq(\n) unless $p = /^##/" Normalize::Text::Music_Fields-G_Gershwin.comp >Music_Fields-G_Gershwin.comp-mail
# (inverse transformation:) Dump pieces listed in mail-header format

# Minimal consistency check of persons database.
perl -MNormalize::Text::Music_Fields -wle "BEGIN{binmode $_, ':encoding(cp866)' for \*STDIN, \*STDOUT, \*STDERR} print Normalize::Text::Music_Fields->check_persons"
# Minimal testing code:
perl -MNormalize::Text::Music_Fields -e Normalize::Text::Music_Fields::test_normalize_piece
It may be easier to type these examples if one uses manage_M_N_F.pm, which
exports the mentioned subroutines to the main namespace (available in
examples directory of a distribution of MP3::Tag). E.g., the last
example becomes:
perl -Mmanage_M_N_F -e test_normalize_piece
