About

BriefLZ is a small and fast open source implementation of a Lempel-Ziv style compression algorithm. The main focus is on speed, but the ratios achieved are quite good compared to similar algorithms.

Usage

The include file brieflz.h contains documentation in the form of doxygen comments. A configuration file is included, so you can simply run doxygen to generate documentation in HTML format.

If you wish to compile BriefLZ on 16-bit systems, make sure to adjust the constants BLZ_HASH_BITS and BLOCK_SIZE.

When using BriefLZ as a shared library (dll on Windows), define BLZ_DLL. When building BriefLZ as a shared library, define both BLZ_DLLand BLZ_DLL_EXPORTS.

The example folder contains a simple command-line program, blzpack, that can compress and decompress a file using BriefLZ. For convenience, the example comes with makefiles for GCC and MSVC.

BriefLZ uses CMake to generate build systems. To create one for the tools on your platform, and build BriefLZ, use something along the lines of:

mkdir build
cd build
cmake ..
cmake --build .

You can also simply compile the source files and link them into your project. CMake just provides an easy way to build and test across various platforms and toolsets.
