This package makes it easy to export and autoload a library of anonymous functions or collections of anonymous functions using composer.

Installation

You can install the package via composer:

composer require inmanturbo/functional-library

Usage

To create a library you can use the HasFunctionalLibrary trait, then you just have to implement a static library method with named bool parameters for your available functions.

You then call static::getLibrary with all your parameters as its args.

Finally, you create a static method called closures() with an associative array of your anonymous functions with (string) keys corresponding to your library method's named params.

Example

use Inmanturbo\FunctionalLibrary\HasFunctionalLibrary;

class ExampleLibrary
{
    use HasFunctionalLibrary;

    public static function library(bool $addOne = false, bool $addTwo = false)
    {
        return static::getLibrary(...func_get_args());
    }

    public static function closures()
    {
        return [
            'addOne' => fn(int $number): int => $number + 1,
            'addTwo' => fn(int $number): int => $number + 2,
        ];
    }
}

Example Usage

The above example creates the following testable api (using pest):

[$addOne, $addTwo] = ExampleLibrary::library(addOne: true, addTwo: true);
expect($addOne(0))->toBe(1);
expect($addTwo(0))->toBe(2);

// Test a single option
$addOne = ExampleLibrary::library(addOne: true);

expect($addOne(0))->toBe(1);

// Test no options (should return all available options)
[$addOne, $addTwo] = ExampleLibrary::library();

expect($addOne(0))->toBe(1);
expect($addTwo(0))->toBe(2);

Now you can put your anonymous functions into scoped static libraries and find them using static analysis by their named arguments, or by inspecting the closures() method's return value.
