ImAKappa / rollang

REPL for DnD rolls

rollang

A DSL and interpreter for DnD rolls. Inspired by Roll20 Dice Reference and Avrae Discord bot

This is just for fun. For actual DnD games, nothing beats real dice :)

Implementation Notes

The interpreter is currently written in Python because that's what I know best at the moment. But I wanna switch to a compiled language soon, so realistically the final interpreter will probably be written in Nim. Although, a functional language might be a better fit, like OCaml or F#.

TODO

• Scanner
• Parser
• Interpreter
• Byte-code interpreter???
• Switch implementation language to one of Nim, OCaml, or F#

Maybe everything should be a function?

The rollang interpreter will execute the file line by line.

Only forward declarations are allowed.

Save your file with a .roll extension, e.g. myfile.roll
