# Scopes

Scopes are configuration-specific entry points to ApisCP. They may tie into config.ini, Bootstrapper, or system configuration. A configuration scope abstracts a more complex operation that could be achieved with blood, sweat, tears, trial, and a bit of error.

# Listing scopes

A list of available scopes can be gathered with cpcmd scope:list. All scopes correspond to a concrete implementations in Opcenter\Admin\Settings.

scope:get retrieves the scope's configured value. A scope value is idempotent; if it's set value is the same as its input it will not rewrite its settings nor process any tasks associated with itself.

scope:info displays the configured value, default value, and description for the scope.

Scopes-list.md contains a master list of all Scopes available to the platform.

# Setting scopes

scope:set reconfigures a scope and initiates any reconfiguration tasks associated with reassignment. Before altering a system value, check scopes first as these will be overwritten with upcp -b (run Bootstrapper).

# Adding new Scopes

Additional Scopes may be latched on at boot using the bootloader of ApisCP. Inside config/custom, create a file named boot.php if it does not exist already. We'll need to register two things, one an autoload path and second, the actual Scope association.

cd /usr/local/apnscp
./artisan make:scope system hello-world

And in config/custom/boot.php:

<?php
apnscpFunctionInterceptor::register(
	\Opcenter\Admin\Settings\System\HelloWorld::class,
	'config/custom/scopes/Opcenter/Admin/Settings/System/HelloWorld.php'
);
\Opcenter\Admin\Settings\Setting::register(\Opcenter\Admin\Settings\System\HelloWorld::class);

In the above, we're creating a class mapping for system.hello-world to config/custom/scopes/Opcenter/Admin/Settings/System/HelloWorld.php. The Scope could just as easily be located in config/custom/scopes/system/hello-world.php.

Now edit the scope in config/custom/scopes/Opcenter/Admin/Settings/System/HelloWorld.php:

<?php declare(strict_types=1);

	namespace Opcenter\Admin\Settings\System;

	use Opcenter\Admin\Settings\SettingsInterface;

	class HelloWorld implements SettingsInterface
	{
		public function set($val): bool
		{
			return error("Nothing to see here");
		}

		public function get()
		{
			return microtime(true);
		}

		public function getHelp(): string
		{
			return 'Dummy command example';
		}

		public function getValues()
		{
			return 'mixed';
		}

		public function getDefault()
		{
			return true;
		}

	}

Then run it!
