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.
Please rate this library. Is it a good library?

Informations about the package procer

Procer

Tests Composer

Procer is a simple and lightweight language designed to describe processes and workflows in a natural and human-readable way. The big advantage of Procer is that it functions can halt the execution of the code and wait for a signal to resume the execution.

Example code:

Each function call in this example code (new_shopping_cart, product_from_store, add, checkout) is actually a function in php land. Here you only write the business logic and the implementation is done in php.

Check the Procer Syntax for more information.

Installation

You can install Procer using composer:

Usage

Usage with custom functions

In order to use custom functions in Procer, you need to create a class that implements the FunctionProviderInterface interface and pass an instance of this class to the Karboosx\Procer constructor.

The CustomFunctionProvider class should look like this:

Note: The supports method should return true if the function is supported by the provider, otherwise it should return false.

Note: The custom_function method should have a Context object as the first argument and an array of arguments as the second argument.

The Context object contains the variables that were defined in the Procer code.

Check the Custom Functions documentation for more information.

Evaluation expression

If you want to evaluate just an expression, you can use the runExpression method of the Karboosx\Procer class.

Check out the Expression documentation for more information.

Pausing and resuming execution

You can pause the execution of the Procer code and resume it later by resume method.

Good way to stop the execution is to use the wait for signal statement.

That way you can pause the execution of the script at one point. Wait for user input, or for some event to happen, and then resume the execution of the script.

Check out the Signals documentation for more information.
Also, check out the Serialization documentation for more information how to serialize and unserialize the script.
