Java-based Befunge Interpreter

Just an attempt at implementing the Befunge-93 spec and Funge-98 spec in java. See https://github.com/catseye/Funge-98/blob/master/doc/funge98.markdown for the spec

1.1 - Support for Befunge '93 spec as per https://esolangs.org/wiki/Befunge.

1.0 - Initial snapshot

Run gradle build and then gradle shadowJar to create the jar file for the release. It'll be located under build/libs

java -jar jbefunge-1.0-SNAPSHOT-all.jar -f hello.bf will execute a befunge 93 file with a tick rate of 1 tick per second. This can be adjusted with the -t argument.

JBefunge supports a debug mode with -d true or --debug true where output is buffered and displayed after the program finishes execution. during this time you will see the cursor moving as a 0 through the application.

Additionally there is -p or --printTrace which will show the operations as they occur so you can track the flow of your program.

I have not extensively tested this interpreter. There may be bugs and errors. Use at your own risk.

Ideally, I'd like to say getting Funge-98 working will be as easy as Befunge-93. I've moved the Funge-98 work to the 2.0 branch. 1.x will be Befunge-93 specs. Personally, I'm enjoying the work on the 93 spec right now and will likely add some stuff to it before the re-write for 98 spec support.

• Make the API friendlier for embedding (in case anyone would want to do that?)
• Add some extensions (Maybe an off-shoot from 1.x? Odd versions 93 spec, even 98?)
  • Would likely be version 3.x using x to enable extensions
• Improve debugging
• Change default values to something more meaningful

• Implement...

• Add Extension commands via x
  • For example xo"txt.olleh""!dlrow ,olleh"xw to write hello, world! to a file hello.txt
• GUI Support? Seems to be all the rage these days...
