1 Parsing simple dice expressions
A simple dice expression can be parsed using
> (simple-roll expression)
For example:
> (define expr "6d6") > (simple-roll expr) '(6 5 3 5 2 2)
2 Parsing full dice expressions
A full dice expression can be parsed using
> (roll expression)
For example:
> (define expr "6d6+1d20-4") > (roll expr) "6d6(6,5,3,5,2,2)+1d20(15)-4" 34
