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

Installation
------------

[](#installation)

You can install the package via composer:

```
composer require inmanturbo/functional-library
```

Usage
-----

[](#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
-------

[](#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
-------------

[](#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.

Testing
-------

[](#testing)

```
composer test
```
