On this page you can find all versions of the php package ruler/ruler. It is possible to download/install these versions without Composer. Possible dependencies are resolved automatically.

FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

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 PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • 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.

Informations about the package ruler

Ruler

Ruler is a simple stateless production rules engine for PHP 5.3+.

Package version Build status StyleCI

Ruler has an easy, straightforward DSL

... provided by the RuleBuilder:

Of course, if you're not into the whole brevity thing

... you can use it without a RuleBuilder:

But that doesn't sound too fun, does it?

Things you can do with your Ruler

Compare things

Math even more things

Reason about sets

Combine Rules

Combine more Rules

evaluate and execute Rules

evaluate() a Rule with Context to figure out whether it is true.

If a Rule has an action, you can execute() it directly and save yourself a couple of lines of code.

Even execute a whole grip of Rules at once

Dynamically populate your evaluation Context

Several of our examples above use static values for the context Variables. While that's good for examples, it's not as useful in the Real World. You'll probably want to evaluate Rules based on all sorts of things...

You can think of the Context as a ViewModel for Rule evaluation. You provide the static values, or even code for lazily evaluating the Variables needed by your Rules.

Now you have all the information you need to make Rules based on Order count or the current User, or any number of other crazy things. I dunno, maybe this is for a shipping price calculator?

If the current User has placed 5 or more orders, but isn't "really annoying", give 'em free shipping.

Access variable properties

As an added bonus, Ruler lets you access properties, methods and offsets on your Context Variable values. This can come in really handy.

Say we wanted to log the current user's name if they are an administrator:

That was a bit of a mouthful. Instead of creating context Variables for everything we might need to access in a rule, we can use VariableProperties, and their convenient RuleBuilder interface:

If the parent Variable resolves to an object, and this VariableProperty name is "bar", it will do a prioritized lookup for:

  1. A method named bar
  2. A public property named bar
  3. ArrayAccess + offsetExists named bar

If the Variable resolves to an array it will return:

  1. Array index bar

If none of the above are true, it will return the default value for this VariableProperty.

Add your own Operators

If none of the default Ruler Operators fit your needs, you can write your own! Just define additional operators like this:

Then you can use them with RuleBuilder like this:

But that's not all...

Check out the test suite for more examples (and some hot CS 320 combinatorial logic action).

Ruler is plumbing. Bring your own porcelain.

Ruler doesn't bother itself with where Rules come from. Maybe you have a RuleManager wrapped around an ORM or ODM. Perhaps you write a simple DSL and parse static files.

Whatever your flavor, Ruler will handle the logic.
