Dark compressor

git clone --recursive https://github.com/kvark/dark cd dark make

Dark aims to be a practical lossless universal data compressor. By combining the security of Rust with the state of art BWT implementation and compression techniques, Dark aims to be the trust-worthy tool for your day-to-day compression needs.

It requires rust-compress, and is developed in cooperation with this wonderful library.

Current status

The compressor can successfully pack and unpack any data in linear time, including the self executable. The following areas are being worked on:

• SACA optimization (BWT forward speed)
• Range/Binary coder optimization (pack/unpack speed)
• BWT-DC model improvements (compression ratio)

Base line

The latest C-version of Dark-0.51 is replicated 1-to-1 here as the Dark compression model. It narrows down book1 to just 214445 bytes. Source of Dark-0.51 is also included in "etc/dark-c/", it was adopted to be multi-platform and include verbose logging.
