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

[](#installation)

Supported installation method is via [composer](https://getcomposer.org):

```
composer require php-standard-library/psalm-plugin --dev
```

Usage
-----

[](#usage)

To enable the plugin, add the `Psl\Psalm\Plugin` class to your psalm configuration using `psalm-plugin` binary as follows:

```
php vendor/bin/psalm-plugin enable php-standard-library/psalm-plugin
```

Type improvements
-----------------

[](#type-improvements)

Given the following example:

```
use Psl\Type;

$specification = Type\shape([
  'name' => Type\string(),
  'age' => Type\int(),
  'location' => Type\optional(Type\shape([
    'city' => Type\string(),
    'state' => Type\string(),
    'country' => Type\string(),
  ]))
]);

$input = $specification->coerce($_GET['user']);

/** @psalm-trace $input */
```

Psalm assumes that `$input` is of type `array`.

If we enable the `php-standard-library/psalm-plugin` plugin, you will get a more specific and correct type of `array{name: string, age: int, location?: array{city: string, state: string, country: string}}`.
