A Ruby VM implemented in JavaScript
RubyScript is a YARV-to-JavaScript compiler which aims to be able to run Ruby in the browser. Although at the moment we're mostly focused on running it on Node.js.
You need:
ruby 1.9.2p180
Then run:
$ cat test.rb
p 123
$ bin/rubyscript-node test.rb
123
lib/rubyscript/yarv/compiler.rb
Uses RubyVM::InstructionSequence
to compile Ruby to YARV bytecode to
JavaScript (which depends on the runtime files described below).
lib/rubyscript/base.js
This defines the object-system of Ruby in JavaScript, including objects, classes, modules, inheritence, singleton classes, mixins and simple lookup.
lib/rubyscript/yarv/base.js
Extends the base with (mostly) YARV specific, rather important, methods.
lib/rubyscript/core.js
Extends the base with core methods (Kernel, Fixnum etc...)
lib/rubyscript/yarv/runner.js
Runs compiled YARV bytecode.
bin/rubyscript
Hooks everything together
