Synopsis

:- use_module(list_util, [take/3]).
?- take(2, [hello, world, etc], Words).
Words = [hello, world].

Description

Prolog code works with lots of lists. This is a collection of predicates that I've found useful from time to time across projects.

Some of these predicates are inspired by functions in Haskell's Data.List library. Prolog's reversible predicates allow us to get by with fewer definitions than Haskell needs.

See list_util.pl documentation below for details about each exported predicate.

Installation

Using SWI-Prolog 6.3 or later:

?- pack_install(list_util).

This module uses semantic versioning.
