Componenta Caster
=================

[](#componenta-caster)

Named value casters and casting pipelines.

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

[](#installation)

```
composer require componenta/caster
```

The package declares `Componenta\Caster\ConfigProvider` in `extra.componenta.config-providers`. When `componenta/composer-plugin` is installed, the provider is added to the generated provider list automatically.

Requirements
------------

[](#requirements)

- PHP 8.4+

Related Packages
----------------

[](#related-packages)

PackageWhy it matters here`componenta/di`Uses casters in `#[Cast]`, `#[QueryParam(cast: ...)]`, and similar attributes.`componenta/validation`Can validate DTOs after values are normalized by casters.`componenta/config`Registers `CasterProviderInterface` through `ConfigProvider`.What It Provides
----------------

[](#what-it-provides)

- `CasterInterface`: public contract for named value casters.
- `CasterProviderInterface`: registry contract for resolving casters by name.
- `CasterProvider`: default registry with scalar, string, array, date, enum, hash, and pipeline casters.
- Typed exceptions when a value cannot be cast.

Basic Usage
-----------

[](#basic-usage)

```
use Componenta\Caster\CasterProvider;

$provider = new CasterProvider();

$int = $provider->provide('int');
$int->cast('42'); // 42
```

Unknown casters return `null`:

```
$provider->provide('missing'); // null
```

Parameterized Casters
---------------------

[](#parameterized-casters)

```
$provider->provide('clamp:10,20')->cast(25); // 20.0
$provider->provide('csv_int')->cast('1,2,3'); // [1, 2, 3]
```

Pipelines
---------

[](#pipelines)

Use `|` to chain casters:

```
$provider->provide('trim|lower')->cast('  HELLO  '); // hello
```

Use `?` to pass `null` through the whole downstream chain:

```
$provider->provide('?int|bool')->cast(null); // null
$provider->provide('?int|bool')->cast('1');  // true
```

DI Registration
---------------

[](#di-registration)

`ConfigProvider` registers `CasterProviderInterface` as a factory returning `CasterProvider`.
