About Curryable
---------------

[](#about-curryable)

**This package is under development, please don't use it on production and wait for the stable release!**

Curryable was created by, and is maintained by [Nuno Maduro](https://github.com/nunomaduro), and is an elegant and simple **curry(f)** implementation in PHP. Currying is an advanced technique of working with functions. It **wraps the given expressions and arguments into a new function** that resolves a value.

Installation & Usage
------------------------

[](#installation--usage)

> **Requires [PHP 7.2+](https://php.net/releases/)**

Create your package using [Composer](https://getcomposer.org):

```
composer require nunomaduro/curryable
```

This helper usage is best described through example in the [Laravel](https://laravel.com) framework:

### On routing

[](#on-routing)

```
Route::get('/', curry('view', 'welcome'));

// Instead of
Route::get('/', function () {
    return view('welcome');
});
```

```
Route::get('user/{id}', curry(User::class)->find());
// Or with Eloquent macro
Route::get('user/{id}', User::curry()->find());

// Instead of
Route::get('user/{id}', function ($id) {
    return User::find($id);
});
```

### On macros

[](#on-macros)

Renaming the `lower` method to `toLower`:

```
Str::macro('toLower', curry()->lower());
// or with the global `strtolower`
Str::macro('toLower', curry('strtolower'));

// Instead of
Str::macro('toLower', function ($value) {
    return Str::lower($value);
});
```

### On collections

[](#on-collections)

Using the global `strtoupper`:

```
$collection = collect(['nuno'])->map(curry('strtoupper')); // ['NUNO']

// Instead of
$collection = collect(['nuno'])->map(function ($name) {
    return strtoupper($name);
});
```

Here is another example using the `each`:

```
// Calls User::create($user) foreach user
collect($users)->each(User::curry()->create());

// Instead of
$collection = collect($users)->map(function ($user) {
    return User::create($user);
});
```

### Dispatching jobs:

[](#dispatching-jobs)

```
dispatch(curry(Artisan::class)->call('horizon:terminate'));

// Instead of
dispatch(function () {
    Artisan::call('horizon:terminate');
});
```

### Curry on class instance methods

[](#curry-on-class-instance-methods)

With global helper:

```
$closure = curry($instance)->instanceMethodName();
$closure($first, $second);

$closure = curry($instance)->instanceMethodName($first);
$closure($second); // just need for the second argument

$closure = curry($instance)->instanceMethodName($first, $second);
$closure(); // no need for arguments
```

With trait `NunoMaduro\Curryable\Curryable`:

```
$closure = $instance->curry()->instanceMethodName();
$closure($first, $second);

$closure = $instance->curry()->instanceMethodName($first);
$closure($second); // just need for the second argument

$closure = $instance->curry()->instanceMethodName($first, $second);
$closure(); // no need for arguments
```

### Curry on class static methods

[](#curry-on-class-static-methods)

```
// Curry on instance methods
$closure = curry(Instance::class)->staticMethodName();
$closure($first, $second);

$closure = curry(Instance::class)->staticMethodName($first);
$closure($second); // just need for the second argument

$closure = curry(Instance::class)->staticMethodName($first, $second);
$closure(); // no need for arguments
```

### Curry on functions

[](#curry-on-functions)

```
// Curry on instance methods
$closure = curry('function_name');
$closure($first, $second);

$closure = curry('function_name', $first);
$closure($second); // just need for the second argument

$closure = curry('function_name', $first, $second);
$closure(); // no need for arguments
```
