Topaz is an implementation of the Ruby programming language, written in Python, using the RPython VM toolchain. Its goals are simplicity of implementation and performance.
You'll need to have a few dependencies installed. You can get them with pip install -r requirements.txt. Finally make sure you have checkout (use tag version release-2.4.0) of PyPy and have it on your PYTHONPATH.
To run the tests:
$ py.testTo translate run:
$ /path/to/pypy/src/rpython/bin/rpython -Ojit targettopaz.pyThis will compile Topaz with a JIT, it'll take 5-10 minutes.
To run Topaz directly on top of Python you can do:
$ python -m topaz /path/to/file.rb
