(Almost) standard compliant Befunge-93 embeddable runtime. A CLI frontend is also available. Read more about Befunge here.

Features:

• No dependencies but Go stdlib.
• Unicode support.
• Improved error handling.
• Deterministic randomness.
• Not turing complete. Eat that, Starlark.

Using the default options, this implementation is almost completely identical to the reference implementation.

Get started:

go install jo-m.ch/go/gobef93/cmd/gobef93@latest
gobef93 -help
gobef93 examples/hello_world.bf
gobef93 -allow_unicode examples/hello_wörld.bf

Check main.go for example usage.

• Allow to step
• Time travel mode
• Better traceability and debugging tools
• Implement remaining options (see TODOs in pkg/bef93/prog.go)
