Lzsslib is an small library for inflating and deflating LZSS (Lempel, Ziv, Storer, Szymanski) buffers.

The LZSS format is originally described in a paper titled "Data Compression via Textual Substitution" published in Journal of the ACM, 29(4):928-951, 1982 by J.A. Storer and T.G. Szymanski.

Installing

Install and update using pip:

$ pip install -U lzsslib

Usage

The following example shows how to decompress a file using default options.

from pathlib import Path
from lzsslib.decompress import LzssDecompressor

# Create a decompressor object with default options
decomp = LzssDecompressor()

# Open an input and output files
fin = Path('input.lzss').open(mode='rb')
fout = Path('output.bin').open(mode='wb')

# Read the input, decompress and write
while (buffer := fin.read(1024)):
    out = decomp.decompress(buffer, remaining_size)
    fout.write(out)

# Ensure output is written and close
fout.flush()
fin.close()
fout.close()
