Version 0.1.0 of the RBzip2 gem has been released. It’s released under the BSD license and its source code is available from GitHub. It’s a pure Ruby implementation of the well-known and widely used bzip2 compression/decompression algorithm. It has no external dependencies and will therefore run on any Ruby implementation (and operating system). This first release offers support for decompressing bzip2 compressed data streams, i.e. IOs. The final aim is to provide a feature-rich and human-friendly API to (de)compress data using various ways.
