Install

Via Composer

$ composer require softius/resources-resolver

Usage

The following resolvers are made available by this library.

• CallableResolver
• FilenameResolver

Usage: CallableResolver

It is possible to resolve the following inputs to the associated callable as it is demonstrated below. This works for static and non-static methods as well and it relies heavily for a Container to be provided.

• App\GreetingController::helloAction to [instance of App\GreetingController, 'helloAction']
• ::helloAction to [instance of calling class, 'helloAction']
• parent::helloAction to [parent instance of calling class, 'helloAction']
• App\SomeClass::someStaticMethod to ['App\SomeClass', 'someStaticMethod']

Resolve a non - static method

use League\Container\Container;
use Softius\ResourcesResolver\CallableResolver;

$container = new Container();
$container->add('App\SomeClass');

$resolver = new CallableResolver($container);

$callable = $resolver->resolve('App\SomeClass::someMethod');;

Resolve a method using alias for class

use League\Container\Container;
use Softius\ResourcesResolver\CallableResolver;

$container = new Container();
$container->add('FooClass', 'App\SomeClass');

$resolver = new CallableResolver($container);

$callable = $resolver->resolve('FooClass::someMethod');;

Resolve a static method

use Softius\ResourcesResolver\CallableResolver;

$resolver = new CallableResolver();

$callable = $resolver->resolve('App\SomeClass::someStaticMethod');

Resolve using parent or self

use Softius\ResourcesResolver\CallableResolver;

class A
{
    public function hi()
    {
        echo 'A: Hi!';
    }
}

class B extends A
{
    public function hi()
    {
        echo 'B: Hi!';
    }
    
    public function test()
    {
        $resolver = new CallableResolver();
        $callable = $resolver->resolve('::hi');         // returns [B, hi]
        $callable = $resolver->resolve('self::hi');     // returns [B, hi]
        $callable = $resolver->resolve('parent::hi');   // returns [A, hi]
    }   
}

Usage: FilenameResolver

Resolve a filename from templates directory

define('TEMPLATES_DIR', '...');

use Softius\ResourcesResolver\FilenameResolver; 

$resolver = new FilenameResolver(TEMPLATES_DIR); 
$filename = $resolver->resolve('path/to/template.php');

It is also possible to omit the extension and specify a global extension for all files to be resolved, like below.

define('TEMPLATES_DIR', '...');

use Softius\ResourcesResolver\FilenameResolver; 

$resolver = new FilenameResolver(TEMPLATES_DIR); 
$resolver->setExtension('php');
$filename = $resolver->resolve('path/to/template');

Many frameworks don't use the directory separator to provide a consistent look across multiple OS. The following example uses '.' as the directory separator without file extensions

define('TEMPLATES_DIR', '...');

use Softius\ResourcesResolver\FilenameResolver; 

$resolver = new FilenameResolver(TEMPLATES_DIR, '.');
$resolver->setExtension('php');
$filename = $resolver->resolve('path.to.template');

Resolve a filename from include path

define('TEMPLATES_DIR', '...');

use Softius\ResourcesResolver\FilenameResolver; 

$resolver = new FilenameResolver(TEMPLATES_DIR);
$resolver->useIncludePath(true);
$filename = $resolver->resolve('path/to/file.php');
