PerlIO::via::Bzip2 - PerlIO layer for Bzip2 (de)compression
use PerlIO::via::Bzip2; # or use PerlIO::via::Bzip2 level => 9; # Maximum compression # Read a bzip2 compressed file from disk. open(my $fh, "<:via(Bzip2)", "compressed_file"); my $uncompressed_data = <$fh>; # Compress data on-the-fly to a bzip2 compressed file on disk. open(my $fh, ">:via(Bzip2)", "compressed_file"); print {$fh} $uncompressed_data; # Set compression level PerlIO::via::Bzip2->level(5); open(my $fh, ">:via(Bzip2)", "compressed_file"); print {$fh} $uncompressed_data;
This module implements a PerlIO layer which will let you handle bzip2 compressed files transparently.
level sets or returns the compression level of the bzip2 library. It ranges from 1 (least compression, most efficient memory use) to 9 (best compression, most memory usage).
This parameter can also be set during using library import, using use PerlIO::via::Bzip2 level => $level.
use PerlIO::via::Bzip2 level => $level
Using binmode() on an opened file for compression will pop (remove) the layer.
This module requires Compress::Bzip2 version 1.03.
