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, ?).

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


API documentation
-----------------

Open the [../../apis/library_index.html#pddl_parser](../../apis/library_index.html#pddl_parser)
link in a web browser.


Loading
-------

To load all entities in this library, load the `loader.lgt` file:

	?- logtalk_load(pddl_parser(loader)).


Testing
-------

The provided unit tests are based on a collection of problem set
files from International Planning Competition 2008. In order to
run all unit tests from the parser's directory type:

	?- logtalk_load(tester).

Or from any directory by typing:

	?- logtalk_load(pddl_parser(tester)).

Some of the unit tests fail in some Prolog compilers due to
limitations to the maximum arity of a term.
