ReFunge is a mostly spec-compliant Funge-98 interpreter written in C#. It can be used as a library or as a standalone program.

Also included in this repository is ReFunge Editor, a simple editor and debugger for Funge-98 programs. It lets you view Funge-Space, IP and stack data, and other useful variables during execution.

• Support for the core Funge-98 language
• File I/O and concurrency are supported
• Currently supported fingerprints:
  • All those defined in the official specification, except for PERL and TURT
  • LONG, FPSP, FPDP, CPLI, 3DSP, BASE
  • More to come!
• Supports arbitrary n-dimensional Euclidean Funges (with Lahey-space wrapping).
• ReFunge Editor:
  • Load and debug Befunge-98 programs
  • View Funge-space, IP, stack, output, and other variables
  • Step through the program or execute it at a set speed (up to 100 instructions per frame)
  • Edit the program, even during execution.
    • Note: Rewinding the program to its initial state is not yet supported.
  • Rotate the Funge-space to view it from different angles!
    • Ctrl-U and Ctrl-O rotate around the axis perpendicular to the screen (Befunge or higher)
    • Ctrl-J and Ctrl-L rotate around the axis going down (Trefunge or higher)
    • Ctrl-I and Ctrl-K rotate around the axis going right (Trefunge or higher)

Breakpoints are planned for the future.

Will be added soon.
