RubyToC has the following modules:

  • Rewriter - massages the sexp into a more consistent form.
  • TypeChecker - type inferencer for the above sexps.
  • RubyToRubyC - converts a ruby (subset) sexp to ruby interals C.
  • RubyToAnsiC - converts a ruby (subset) sexp to ANSI C.

and the following tools:

  • translate.rb - Translates a given file to C.

Changes:

1.0.0.7 / 2009-08-18

  • 1 bug fix:

    • Removed unnecessary require on unified_ruby

  • translate.rb - Translates a given file to C.

“ruby_to_ruby_c”; p RubyParser.new.parse(File.read(“hello.rb”))’
