A toy implementation of a simple gzip-like LZSS text compressor written in Nim. This project is part of the compressor course at the Paris-East Marne-la-Vallée university.

Test and build

Building this project requires Nim and Nimble version 0.19.0 or later.

  • nimble build produces a binary named gziplike
  • nimble test runs the included unit tests
