Compress::unLZMA - Interface to LZMA decompression library
use Compress::unLZMA qw(uncompress uncompressfile); my $data = uncompressfile('foo.lzma'); my $data = uncompress($content);
LZMA is default and general compression method of 7z format in 7-Zip program. LZMA provides high compression ratio and very fast decompression.
This module is based on the LZMA SDK which provides a cross-platform implementation of the LZMA decompression algorithm in ANSI C.
From SDK lzma.txt file:
LZMA decompression code was ported from original C++ sources to C. Also it was simplified and optimized for code size. But it is fully compatible with LZMA from 7-Zip.
- $data = uncompress($content)
Uncompress $data. if successful, it returns the uncompressed data. Otherwise it returns undef and $@ contains the error message.
The source buffer can be either be a scalar or a scalar reference.
- $data = uncompressfile($file)
Uncompress the file $file. if successful, it returns the uncompressed data. Otherwise it returns undef and $@ contains the error message.
This version only implements in-memory decompression (patches are welcomed).
There is no way to recognize a valid LZMA encoded file with the SDK. So, in some cases, you can crash your script if you try to uncompress a non valid LZMA encoded file.
