RulerZBundle

This bundle integrates RulerZ into Symfony.

Installation

Require the bundle:

composer require 'wallabag/rulerz-bundle'

And declare it into your app/AppKernel.php file:

public function registerBundles()
{
    return array(
        // ...
        new KPhoen\RulerZBundle\KPhoenRulerZBundle(),
    );
}

Usage

This bundle registers a rulerz service which is an instance of RulerZ\RulerZ.

$rulerz = $this->container->get('rulerz');

$rulerz->filter(/* ... */);

See RulerZ's documentation for more information.

Custom operators

Custom operators can be added to RulerZ executors. The bundle provide a way to register new operators directly from the container, you just need to tag a service:

services:
    operator.array.like:
        class: RulerZ\Operator\ArrayExecutor\Like
        tags:
            - { name: rulerz.operator, target: native, operator: like }

In addition to the rulerz.operator tag, two other values are needed:

• target: the compilation target we want to register the operator for ;
• operator: the name that will be given to the operator in rules.

Important: Operators registered as classes must implement the __invoke magic method as RulerZ expects custom operators to be defined as callable.

Validators

A rule validator is provided by the bundle. In its simplest form, it will only validate the syntax of a given rule. Unknown variables or operators won't be detected unless you define a whitelist of accepted values.

use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Bridge\RulerZ\Validator\Constraints as RulerZAssert;

class TaggingRule
{
    /**
     * @var string
     *
     * @Assert\NotBlank()
     * @RulerZAssert\ValidRule(
     *  allowed_variables={"title", "url", "isArchived", "isStared", "content", "language", "mimetype", "readingTime", "domainName"},
     *  allowed_operators={">", "<", ">=", "<=", "=", "is", "!=", "and", "not", "or"}
     * )
     */
    private $rule;
}
