### Tools for creating fluent interfaces.

[](#tools-for-creating-fluent-interfaces)

Fluidity provides a set of middleware interfaces that aid in the development of libraries that themselves aim to provide fluid interfaces.

---

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

[](#installation)

This package requires PHP 8.4 or higher.

Install via Composer:

```
composer require decodelabs/fluidity
```

Usage
-----

[](#usage)

### Method chaining

[](#method-chaining)

```
namespace DecodeLabs\Fluidity;

interface Then
{
    public function then(callable $callback): Then;
    public function thenEach(iterable $values, callable $callback): Then;
    public function thenIf(?bool $truth, callable $yes, callable $no=null): Then;
    public function thenUnless(?bool $truth, callable $no, callable $yes=null): Then;
}
```

Create fluent object interfaces with basic generic logic structure support.

```
use DecodeLabs\Fluidity\Then;
use DecodeLabs\Fluidity\ThenTrait;

$test = new class() implements Then {
    use ThenTrait;

    public function doThing(int $value=null) {}
};

$truth = true;

$test
    ->then(function($test) {
        $test->doThing();
    })

    ->thenEach([1, 2, 3], function($test, $value) {
        // Called three times
        $test->doThing($value);
    })

    ->thenIf($truth, function($test) {
        // This gets called if($truth)
    }, function($test) {
        // This get called otherwise
    })

    ->thenUnless($truth, function($test) {
        // This gets called if(!$truth)
    }, function($test) {
        // This get called otherwise
    });
```
