This repository contains a simple Cython wrapper for the finite state entropy codec by Yann Collet based on asymmetric numeral systems by Jarek Duda).

The wrapper implements only the basic compress & decompress functions from the original codec. Both functions operate on bytes objects:
import pyfse
x = bytes([x % 3 for x in range(100)])
y = pyfse.compress(x)
X = pyfse.decompress(y)
x == XThere is also a simple demo script to show a text coding example:
