NAME

Soar::Production - REPRESENT SOAR PRODUCTIONS

VERSION

version 0.03

SYNOPSIS

use Soar::Production qw(prods_from prods_from_file);
my $prods = prods_from_file( '/path/to/file' );
for my $prod (@$prods){
    print $prod->name . "\n";
}
my $prod =
'sp{myName
    (state <s>)
    -->
    (<s> ^foo bar)
}';
my $prod = Soar::Production->new($prod);

DESCRIPTION

This is a module for storing, manipulating, and querying Soar productions. There isn't much functionality implemented, yet. Currently there are functions for

NAME

Soar::Production- Store and manipulate Soar productions

METHODS

new

Argument: text of a Soar production. Creates a new production object using the input text.

name

Optional argument: name to assign production. Sets the name of the current production if an argument is given. Returns the name of the production.

EXPORTED FUNCTIONS

The following functions may be exported:

prods_from_file

A shortcut for prods_from(file = $arg)>.

prods_from

This method extracts productions from a given text. It returns a reference to an array containing production objects. Note that all comments are removed as a preprocessing step to detecting and extracting productions. It takes a set of named arguments: file- the name of a file to read. text- the text to read. You must choose to export this function via the use function:

use Soar::Production qw(prods_from);

TODO

state_name

Set/get name of matched state

superstate_name

Set/get name of matched state's superstate

type

Does this production match a state or an impasse?

validate

Check this production against a datamap.

check semantic correctness

Soar::Production::Parser does not check semantic correctness. The following are good things to check:

  • everything matched in RHS must be in LHS
  • no empty RHS
  • Only allowable non-operator preference is REJECT
  • Check for existence of RHS function
  • not connected
  • disconnect from goal or impasses (no 'state' or 'impasse' keyword)
