I really like this pack because it allows me an extra level of specific checking/safety on top of the already existing types in swi-prolog. As mentioned, this works very well with mavis. This makes programming in prolog even more enjoyable.

This pack is a great way to define algebraic datatypes. Once defined, these types are automatically supported by must_be/2, library(mavis), etc.

This package provides library(typedef), a small library for processing type declarations.

See library(typedef) module header for more information.

Quick test

This is a small test file that you can use to check if it works.

:- use_module(library(typedef)).

:- type maybe(A) ---> nothing; just(A).
:- type natural == nonneg.

%% test(+A:natural, +B:maybe(natural)) is det.
test(A,B) :-
        must_be(natural,A),
        must_be(maybe(natural),B).
