Metaruby intends to implement ruby’s internals in ruby itself. Its implementation will use ruby2c to convert itself to C and bootstrap a new ruby binary. Metaruby should be fully compatible w/ Matz’s ruby.

Current Status:

• Ruby2C
  • [DONE] ParseTree can extract AST from Ruby directly.
  • [DONE] Type inference of AST - still needs polymorphic TI.
  • [DONE] Generates C code for minimial subset of ruby.
  • [SOME] Generates C code for maximal subset of ruby.
  • [NONE] Translator can translate interpreter.
• Test Suite and Specification/Documentation
  • [SOME] rubicon audited and ported to BFTS
• Library
  • [DONE] Array - implemented and passing tests
  • [DONE] Comparable - implemented and passing tests
  • [DONE] Enumerable - implemented and passing tests
  • [DONE] Exception - implemented and passing tests
  • [DONE] FalseClass - implemented and passing tests
  • [DONE] FileTest - implemented and passing tests
  • [DONE] Hash - implemented and passing tests
  • [DONE] NilClass - implemented and passing tests
  • [DONE] Range - implemented and passing tests
  • [DONE] String - implemented and passing tests
  • [DONE] Struct - implemented and passing tests
  • [DONE] Time - implemented and passing tests
  • [DONE] TrueClass - implemented and passing tests
  • [SOME] fill out the rest of this list
• GC
  • [NONE] not a damn thing has been done to even look at this yet.
• Parser/Interpreter
  • [NONE] not a damn thing has been done to even look at this yet. We’re hoping the ruby-grammarians project or others will help on this front.
