In the past three years, the Rubinius project has evolved from a hobby attempt to implement Ruby using as much Ruby as possible to a full-featured system boasting an extremely fast VM, advanced garbage collector, and LLVM-based profile-driven JIT with run-time type feedback.

As with the Java Hotspot VM, these features make Rubinius an attractive platform for experimenting with implementing other languages.

The Lua programming language is known to have very fast implementation and Lua has been used from the beginning for data processing tasks. LPEG is an implementation of a Parsing Expression Grammar (PEG) using a stack machine. The performance of LPEG is on par with a parser generated by Lex/Yacc for some tasks.

Pegarus is an implementation of the LPEG ideas on the Rubinius platform. Pegarus is used as the parser to implement Poison, a version of _why’s Potion programming language.

This talk will describe Rubinius as a platform for implementation of languages other than Ruby. Details of implementing Pegarus and Poison will be provided. Both these projects are experimental.

Interested in languages of all types, I currently consider Ruby to be my favorite. My hope with Rubinius is to create the an excellent Ruby implementation that enables us to easily explore and adopt the best features of other programming languages.
