Rc/Funge-98

This website is the official website of Rc/Funge-98 and is back after a long absence. I am the original author of Rc/Funge-98, which was one of the first fully-compliant Funge-98 implementations.

After a long diversion into other hobbies, I have decided to once again work on my Rc/Funge-98 system.

• The 1.x source has undergone a major rewrite of the underlying Rc/Funge engine that will allow for some exciting new capabilites. This new version will be titled Rc/Funge-98 V2 which will be considered a different project than the 1.x branch. Only the 2.x branch will receive new fingerprints or major upgrades. Capabilites of the new Rc/Funge-98 V2 will be posted shortly

• Funge-98 and Funge-93 modes
• Supports Unefunge, Befunge, and Trefunge
• Concurrent Funge, 't' command is implemented
• 'i', 'o', and '=' commands implemented
• Can map funge space to screen, with command tracing
• Full command tracing with stack output
• Fixed memory model for speed
• Dynamic memory model for large dimensions
• Mini-Funge for user definable A-Z functions

Rc/Funge-98 defined fingerprints

Official specification for RCS-defined fingerprints

Addendum to TRDS

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.
• Remote/Funge - A new fingerprint FRPC has been added that allows a funge program to contact and execute funge procedures on remote funge servers.

Official Funge-98 Specification
Funge-98 was originally defined by Chris Pressey of Cat's Eye Technologies. As of this time the Cat's Eye Technologies website has gone dark and the original Funge-98 website is no more. Below is a copy of the original specification published by Cat's Eye Technologies:

Here also is Cat's Eye's original diagnostics

Funge-98 tutorial

Here is my beginning work on a tutorial for Funge-98. As I write each part of the tutorial, it will be posted here, so check back often
