Lempel-Ziv-Storer-Szymanski via Words compression algorithm.

This module implements the LZSSW compression algorithm, a variant of LZSS. The algorithm maintains a ring buffer and uses bit flags to indicate compressed vs uncompressed data.

The compressor parameters can be tuned for different use cases: - Ring buffer size controls how far back to look for matches - Maximum match length affects compression ratio vs processing time - Common byte value can be optimized for specific data types

Attributes

RING_SIZE_MIN	Minimum ring buffer size.
RING_SIZE_MAX	Maximum ring buffer size.
RING_SIZE_DEF	Default uses maximum size.
MAX_MATCH_LEN_MIN	Minimum match length limit.
MAX_MATCH_LEN_MAX	Maximum match length limit.
MAX_MATCH_LEN_DEF	Default match length.
COMMON_BYTE_DEF	Default byte value used to fill the initial ring buffer.

Functions

compress	Compresses data using the LZSSW algorithm.
decompress	Decompresses LZSSW-compressed data.
main	Command-line interface for LZSSW compression/decompression.
open	Opens an LZSSW compressed file.

Classes

LZSSWCompressor	LZSSW compression implementation.
LZSSWDecompressor	LZSSW decompression implementation.
LZSSWFile	File-like object for reading/writing LZSSW compressed files.

Exceptions

LZSSWException

Exception raised for LZSSW compression/decompression errors.
