Spingus

A simple, fast, and robust PDDL parser

Spingus has three goals:

  • Robust - Is tested on commenly used PDDL domains and problems
  • Fast - Optimised and benchmarked to be as fast as possible
  • Simple - Avoids rarely used PDDL syntax in favor of easy of use

Example

use spingus::problem::objects::Object;
let input = "(define (problem prob)
                  (:objects o1)
                  (:init (p o1))
                  (:goal (not (p o3)))
             )";
let problem = spingus::problem::parse(&input);
assert_eq!(problem.name, Some("prob"));
assert_eq!(problem.domain, None);
assert_eq!(problem.objects, Some(vec![Object { name: "o1", type_name: None }]));
//...
