A project to create a Befunge93/98 interpreter and debugger using C#

BefungeSharp - The Premier Funge-98 IDE for Windows

BefungeSharp is a Funge-98 IDE that aims to have the best Befunge code editor, a fully compliant interpreter, and useful debugging features like edit and continue, all while being very easy to use!

=========================

Be sure to read the "4 Minute Intro" if you are unfamiliar with Befunge.

If you are running on Windows 10, you will likely need to turn on "Legacy Command Prompt", and possibly run the program in compatability mode. Expect some graphical glitches as the console refresh timing is different on newer computers.

Why does this need to exist?

This project fills the void for Windows users who want to quickly get started with Funge-98 (not just Befunge-93,) without complex compilation, and, most of all, want to see the IP dance around FungeSpace. In addition, the Funge specific editor makes writing Funge code much more enjoyable than using Notepad. No other Funge tool combines these features.
