The parser is a C extension named melbourne. It is basically the parser from MRI wrapped up in a way that can be used in Rubinius. The parser converts Ruby source code to an internal parse tree of nodes. The parse tree is processed by calling a Ruby method for each node. The processor is in lib/melbourne/processor.rb. The methods in the processor create Ruby objects that are nodes in an abstract syntax tree (AST). The AST is processed to generate bytecode.
