Description

A dice expression parser in C to use for rolling dices in RPGs etc.

Here's a grammar for a dice expression.

s      ::= expr
expr   ::= INTEGER | ('-'|'+') expr | expr '-' expr | expr '+' expr |
           [INTEGER] ('d'|'D') INTEGER ignore
ignore ::= ('<' | '>' [INTEGER])*

Example expression:

3d6< + 3d4>2 + d2 - 1

Roll d6 three times, discard smallest value, plus roll d4 three times, discard two largest values, plus roll d2 once, minus 1.
