FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

The full documentation is here.
This bundle implements 3 design patterns (Specification, Rules and Chain of responsibility) in order to define a system to help you to create your own business rules.
There are 3 important objects in this conception :
- Specification : This is your business condition. It is used to define if a business rule has to be executed on the current candidate.
- Rule : This is your business rule.
- RulesEngine : This object contains several rules and executes ones which have to be executed on the current candidate.
Please, feel free to see the demo.
Basic Usage
Create a Specification
The specification class
You can generate this class with the next command bin/console make:specification IsDummySpecification.
Create a Rule
The rule class
Thanks to the private constant BUSINESS_LOGIC_TAGS you can dynamically add tags on your rule.
This constant must be an array of arrays. Each array corresponds to a tag. The first argument must be a string
and it is corresponding to the tag name. The second one is optional, it must be an integer and it is corresponding to the priority.
You can generate this class with the next command bin/console make:rule DummyRule.
The service declaration
You dont need to declare your rules into the services.yml file thanks to the indication implements RuleInterface.
If you decide to declare it into this file, the tags that you defined will be automatically merged with those of the constant.
For instance, the DummyRule will be tagged with : rule.user.vip, rule.user.basic, rule.user.awesome and rule.user.another_tag.
Create a RulesEngine
