README
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.
