Description

Add-on for shinepress/framework to allow registering of global variables, functions, and constants for use outside of modules.

Installation

The recommendend installation method is with composer:

$ composer require shinepress/globals

Usage

Add the 'RegisterGlobal' attribute to any module class/property/constant/method to register it into the global namespace.

Module Instance

use ShinePress\Framework\Module;
use ShinePress\Globals\RegisterGlobal;

#[RegisterGlobal('module')] // registers as $module
#[RegisterGlobal] // registers as $ExampleModule
class ExampleModule extends Module {

	public function hello(): string {
		return 'world';
	}
}

ExampleModule::register();

global $module;
print $module->hello();
// prints: 'world'

global $ExampleModule;
print $ExampleModule->hell();
// prints: 'world'

Module Property

Assigns a reference to the indicated class property to the global variable regardless of visibility.

use ShinePress\Framework\Module;
use ShinePress\Globals\RegisterGlobal;

class ExampleModule extends Module {

	#[RegisterGlobal('testProperty')]
	public string $myProperty = 'foo';
}

ExampleModule::register();

global $testProperty;
print $testProperty;
// prints: 'foo';

$testProperty = 'bar';
print ExampleModule::instance()->myProperty;
// prints: 'bar'

Module Constant

Defines a global constant with the value of the class constant regardless of visibility.

use ShinePress\Framework\Module;
use ShinePress\Globals\RegisterGlobal;

class ExampleModule extends Module {

	#[RegisterGlobal('TEST_CONSTANT')]
	public const MY_CONSTANT = 'foobar';
}

ExampleModule::register();

print TEST_CONSTANT;
// prints: 'foobar'

Module Method

Creates a closure reference to the indicated method and assigns it to a function in the global scope.

Note: the relies on eval, with all the associated downsides.

use ShinePress\Framework\Module;
use ShinePress\Globals\RegisterGlobal;

class ExampleModule extends Module {

	#[RegisterGlobal('toLowercase')]
	public function lowercase(string $input): string {
		return strtolower($input);
	}

	#[RegisterGlobal('toUppercase')]
	public function uppercase(string $input): string {
		return strtoupper($input);
	}
}

ExampleModule::register();

print toLowercase('HELLOWORLD');
// prints: 'helloworld'

print toUppercase('helloworld');
// prints: 'HELLOWORLD'
