=head1 NAME
Encode::Arabic::Parkinson - Dil Parkinson's transliteration of Arabic
=head1 REVISION
$Revision: 179 $ $Date: 2007-01-14 01:23:25 +0100 (Sun, 14 Jan 2007) $
=head1 SYNOPSIS
use Encode::Arabic::Parkinson; # imports just like 'use Encode' would, plus more
while ($line = <>) { # Dil Parkinson's mapping into the Arabic script
print encode 'utf8', decode 'parkinson', $line;
}
# shell filter of data, e.g. in *n*x systems instead of viewing the Arabic script proper
% perl -MEncode::Arabic::Parkinson -pe '$_ = encode "parkinson", decode "utf8", $_'
# employing the modes of conversion for filtering and trimming
Encode::Arabic::enmode 'parkinson', 'nosukuun', 'LWE xml';
Encode::Arabic::Parkinson->demode(undef, undef, 'strip _');
$decode = "AiqoraLo hRvaA Ol_n~a_S~a bi___OnotibaAhI.";
$encode = encode 'parkinson', decode 'parkinson', $decode;
# $encode eq "AiqraL hRvaA Aln~aS~a biAntibaAhI."
=head1 DESCRIPTION
Dil Parkinson's notation is a one-to-one transliteration of the Arabic script for Modern Standard
Arabic, using lower ASCII characters to encode the graphemes of the original script.
=head2 IMPLEMENTATION
Similar to that in L<Encode::Arabic::Buckwalter|Encode::Arabic::Buckwalter>.
=head2 EXPORTS & MODES
The module exports as if C<use Encode> also appeared in the package. The other C<import> options are
just delegated to L<Encode|Encode> and imports performed properly.
The B<conversion modes> of this module allow to override the setting of the C<:xml> option, in addition to
filtering out diacritical marks and stripping off I<kashida>. The modes and aliases relate like this:
our %Encode::Arabic::Parkinson::modemap = (
'default' => 0, 'undef' => 0,
'fullvocalize' => 0, 'full' => 0,
'nowasla' => 4,
'vocalize' => 3, 'nosukuun' => 3,
'novocalize' => 2, 'novowels' => 2, 'none' => 2,
'noshadda' => 1, 'noneplus' => 1,
);
=over
=item enmode (I<$obj,> $mode, $xml, $kshd)
=item demode (I<$obj,> $mode, $xml, $kshd)
These methods can be invoked directly or through the respective functions of L<Encode::Arabic|Encode::Arabic>. The
meaning of the extra parameters follows from the L<examples of usage|/SYNOPSIS>.
