pylzss

library0.3.8pypypiunverified

pylzss is a Python library designed for decoding and encoding data compressed with the LZSS algorithm. It provides efficient handling of LZSS-compressed streams, often found in embedded systems or older file formats. The current version is 0.3.8, with recent releases focusing on bug fixes, build system improvements, and wider platform support.

LzssDecoder

✗ from pylzss.include import LzssDecoder

LzssEncoder

✓ from pylzss import LzssEncoder

This quickstart demonstrates how to use `pylzss` to compress and decompress a byte string. It initializes an `LzssEncoder` to compress the `original_data` and then uses an `LzssDecoder` to reconstruct it, verifying that the decoded data matches the original.

from pylzss import LzssEncoder, LzssDecoder # Example data original_data = b"A Python library for decoding/encoding LZSS-compressed data. " * 5 # Encode the data encoder = LzssEncoder() encoded_data = encoder.encode(original_data) print(f"Original size: {len(original_data)} bytes") print(f"Encoded size: {len(encoded_data)} bytes") # Decode the data decoder = LzssDecoder() decoded_data = decoder.decode(encoded_data) print(f"Decoded size: {len(decoding_data)} bytes") assert original_data == decoded_data print("Encoding and decoding successful!")

Debug

Known issues

breakingVersion 0.3.5 was pulled from PyPI due to critical issues. Attempting to install or use it will lead to unexpected behavior or installation failures.

fix

Always use `pylzss` version 0.3.6 or newer. If you have 0.3.5 installed, upgrade immediately with `pip install --upgrade pylzss`.

affects: 0.3.5

breakingVersion 0.3.3 was incorrectly versioned and never properly released to PyPI. It should be avoided as it may cause installation problems or contain critical bugs.

fix

Do not attempt to use or install `pylzss==0.3.3`. Use `pylzss==0.3.4` or any newer version.

affects: 0.3.3

gotchaVersions of `pylzss` older than 0.3.1 can raise a `SystemError` when used with Python 3.10 or newer due to API changes in Python's C extension handling.

fix

Ensure you are using `pylzss` version 0.3.1 or newer. Upgrade with `pip install --upgrade pylzss` if you are on an older version and Python 3.10+.

affects: <0.3.1
