A Warren's Abstract Machine for Symfony 2.3
-------------------------------------------

[](#a-warrens-abstract-machine-for-symfony-23)

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

Version 1.5

What ?
------

[](#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](https://packagist.org/packages/trismegiste/wam-prolog)

Install
-------

[](#install)

```
$ composer.phar require trismegiste/prolog dev-master
```

CLI with symfony 2.3
--------------------

[](#cli-with-symfony-23)

Open a command line interface and type :

```
php app/console wam:prolog:console
```

Service for symfony 2.3
-----------------------

[](#service-for-symfony-23)

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

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