Cardinal is a Ruby compiler for Parrot Virtual Machine.
The parser is fairly complete. The standard library exists, but still needs filling out.
Cardinal's parser is very very slow. You can precompile to PIR with –target=pir and run the result with Parrot directly to skip the parsing phase. (You may need cardinal.pbc in the same directory for this to work.)
Get a copy of Cardinal (read only):
git clone git://github.com/parrot/cardinal.git
After obtaining the source code, run:
To run some tests run:
rake test:all rake test:[name]
You might get all rake tasks with:
You can also build cardinal with Winxed (which comes with Parrot)
winxed setup.winxed build
winxed setup.winxed test
Note that some of them will probably fail, as Cardinal is not yet complete
If you want to install Cardinal to your Parrot install directory, run:
winxed setup.winxed install
The compiler will be available as parrot-cardinal
Follow the documentations to start developing cardinal.
