Re: Including a 480K data file with a module

[Graciliano M. P.]

You should compress the data and than append it with __DATA__ or as a string
saved with Base64 to avoid binary errors.

Here's a simple sample:

  use Compress::Zlib qw(compress uncompress) ;
  use MIME::Base64 qw(encode_base64 decode_base64) ;

  my $uncompressed = 'some sample data' ;

  my $base64 = encode_base64( compress($uncompressed) ) ;

  print "$base64\n" ;

  my $original = uncompress( decode_base64($base64) ) ;

  print "$original\n" ;

Regards,
Graciliano M. P.
