Rbfunge is a Befunge-93 interpreter for Ruby (although I may implement Befunge-98 support later). Right now it’s not so perfect, but I’ll keep working on it.
To installl rbfunge:
% gem install rbfunge
Once rbfunge is installed, you can use it to interpret your Befunge-93 code.
Load a file via the command line:
% rbfunge test.bf

0.1.0 - Initial release. Pretty unstable.
