NAME

6       Language::Prolog::Types::Factory - Perl extension to construct Prolog
7       types
8

SYNOPSIS

10         use Language::Prolog::Types::Factory;
11         print prolog_functor("hello",2,3,4);
12         print prolog_list(3,4,5);
13
14         etc.

ABSTRACT

17       Factory module for Prolog terms.
18
19       Implements a pluggable interface that lets the constructor functions be
20       changed to use different implementations for the actual prolog terms.
21
22       This module should be rarely used, only when interfacing Perl with a
23       different Prolog system if the default representations for Prolog terms
24       are not adecuate.
25

DESCRIPTION

27       This module implements a set of constructor functions for Prolog terms.
28
29       Internally the module use a factory object implementing "new_nil",
30       "new_list", "new_ulist", "new_functor" and "new_variable". Look at
31       Language::Prolog::Types::Internal for a real implementation of the
32       factory interface.
33
34       There is also some intelligency added to the consructors to
35       automatically promote types to others more adecuate. i.e. a '.'/2
36       functor to a list or [] to nil.
37
38       Constructor functions are reexported from Language::Prolog::Types and
39       you should use that module instead of this one.
40
41   EXPORT
42       prolog_nil()
43           returns nil term.
44
45       prolog_list(@terms)
46           returns a prolog list containing terms <@terms>.
47
48       prolog_ulist(@terms, $tail)
49           returns an unfinished list with terms @terms and tail $tail.
50
51       prolog_functor($name, @terms)
52           returns a functor with name $name and arguments @terms.
53
54       prolog_variable($name) =item prolog_var($name)
55           return a new varaible with name $name
56
57       prolog_atom($atom)
58           Is not a contructor but converts any perl construct $atom to an
59           atom.
60
61       prolog_string($string)
62           returns a prolog list formed by the ASCII values of $string.
