A Warren's Abstract Machine for Symfony 2.3

Original java version by Stefan Büttcher.
PHP port, PhpUnit tests and bundle for Symfony2.3 by Florent Genette.

Version 1.5

What ?

A Warren Abstract Machine (WAM) is a virtual machine (like a JVM for Java) for Prolog. This library is intended to run on PHP 5.4 and preferably on Symfony 2.3. Prolog is a logic language which solve problems with an inference engine.

This bundle uses my standalone prolog library trismegiste/wam-prolog


$ composer.phar require trismegiste/prolog dev-master

CLI with symfony 2.3

Open a command line interface and type :

php app/console wam:prolog:console

Service for symfony 2.3

You can read PrologGuiController.php. Here is an example :

$machine = $this->get('prolog.wam');
$compiler = new Prolog\PrologCompiler($machine);
$code = $compiler->compile($prog);
$result = $machine->runQuery($query);
