This PDDL 3.0 file parser converts PDDL files to Logtalk/Prolog friendly syntax. For example:

PDDL         Prolog
(on ?x ?y)   on(?x, ?y)
Syntax sugar: op(200, fy, ?).
Usage: The PDDL parser can be loaded from its directory by typing: ?- logtalk_load(loader). Or from any directory by typing: ?- logtalk_load(pddl_parser(loader)).

For whole example check the "pddl.lgt" file for usage and example output.

Validation: The provided unit tests are based on a collection of problemset files from International Planning Competition 2008. in order to run all unit tests from the parser's directory type: ?- logtalk_load(tester). Some of the unit tests fail in some Prolog compilers due to limitations to the maximum arity of a term.
