Rc/Funge-98 V2

Rc/Funge-98 V2 consists of a major restructuring of the underlying Rc/Funge engine. This restructuring allows for some exciting new capabilities for Rc/Funge-98:

  • Funge/Multiverse - With this new capability Rc/Funge-98 is capable of running more than just a single Funge VM, or universe and allows for any number of universes to exist and run together. A new fingerprint, MVRS, has been added that allows data to be copied from one universe to another and even allows IPs to travel from one universe to another.
    Funge/Multiverse allows each VM to be completeley self-contained! One VM can be running Befunge while another is running Unefunge and yet another running Trefunge. Each VM can also be running its own language variant, one can be running Funge/98 while another runs Funge/93 and yet another runs some other language variant.
  • Object/Funge - A new fingerprint, FOBJ has been added to allow for semi-object-oriented funge. Each object is its own VM and may contain any number of method handlers. Methods executed on a Funge object take just 1 tick from the perspective of the calling IP.
  • Mini-Funge has been scrapped and replaced with an all new dynamic fingerprint engine. Now fingerprints have the full power of the Rc/Funge VM at their fingertips. All commands are now available to fingerprints, including i, o, =, t, fingerprint loading and more.
