CGN-CLI (Compressed Game Notation Command Line Interface)

CGN-CLI is a simple command line interface for the CGN (Compressed Game Notation) library I created. It allows you to compress and decompress PGN files using the CGN library. It is designed to be fast, efficient, and flexible. It supports WASM compilation via wasm-pack, and contains 4 different compression algorithms to choose from.

Algorithms (High to Low Compression Ratios --- Low to High Speed)

1. opening-huffman - A Huffman encoding algorithm that uses the huffman-encoding crate to compress the PGN data, but with an additional optimization for compressing common opening moves.
2. dynamic-huffman - A Huffman encoding algorithm that uses the huffman-encoding crate to compress the PGN data, but with a huffman tree that is updated dynamically as the data is compressed.
3. huffman - A Huffman encoding algorithm that uses a huffman-encoding crate to compress the PGN data.
4. bincode - A simple binary encoding algorithm that uses the bincode crate to serialize the PGN data into a binary format.

Installation

Ensure you have Rust installed on your system. Then run the following command:

cargo install cgn-cli
