NAME

App::Brl2Brl - Convert between braille display tables defined in Liblouis.

VERSION

Version 0.04

SYNOPSIS

This module is useful if you have a text coded for one braille character set and need to convert it to another, e.g. you have a text in North American ASCII or Eurobraille and you need it in Unicode braille.

use App::Brl2Brl;

my $brl_obj = App::Brl2Brl->new({ # to read in the specified files and store the characters/dots in hashes
  path => '/usr/share/liblouis/tables', # path to liblouis tables
  from_table_file => 'en-us-brf.dis', # or another display table
  to_table_file => 'unicode.dis', # or another display table
  warn => 1, # if you want to be warned if a char isn't defined in table
});
my $out = $brl_obj->switch_brl_char_map('ABC123'); # switch from BRF to Unicode braille
print "$out\n";

Or you may do:

use App::Brl2Brl;

my $table_path = '/usr/share/liblouis/tables/';
my $from_table_file = 'en-us-brf.dis';
my $to_table_file = 'unicode.dis';

my %from_table = parse_dis( "$table_path/$from_table_file" );
my %to_table = parse_dis( "$table_path/$to_table_file" );
while( <> ){
  my $out = Conv( \%from_table, \%to_table, $_);
  print "$out\n";
};
