[Cycle ORM](https://github.com/cycle/orm) uses an object implementing the `Cycle\ORM\SchemaInterface` interface as a schema.
This schema can be constructed from a PHP array with a specific structure. The package at hand offers a comprehensive
solution for building a schema from different sources. It includes a collection of providers that implements the
`Cycle\Schema\Provider\SchemaProviderInterface` interface. These providers are grouped in the
`Cycle\Schema\Provider\Support\SchemaProviderPipeline`.

This pipeline orchestrates the execution of providers in a predetermined order, one after another.
If one of the providers returns the schema, subsequent providers are not executed.

## Requirements

Make sure that your server is configured with the following PHP versions and extensions:

- PHP >=8.0

## Installation

You can install the package via Composer:

```bash
composer require cycle/schema-provider
```

## Usage

Let's explore a straightforward example of schema creation using this package. For example, we have a schema in
two php files **schema1.php** and **schema2.php**. In this scenario, we can use the
`Cycle\Schema\Provider\FromFilesSchemaProvider` to build the schema from multiple files. Before this provider,
we can add a `Cycle\Schema\Provider\SimpleCacheSchemaProvider`, capable of caching the schema. Upon subsequent schema
builds, this provider retrieves the schema from the cache, eliminating the need to build the schema using
`FromFilesSchemaProvider`.

```php
use Cycle\ORM\Schema;
use Cycle\Schema\Provider\FromFilesSchemaProvider;
use Cycle\Schema\Provider\SimpleCacheSchemaProvider;
use Cycle\Schema\Provider\Support\SchemaProviderPipeline;

$pipeline = (new SchemaProviderPipeline($container))->withConfig([
SimpleCacheSchemaProvider::class => SimpleCacheSchemaProvider::config(key: 'cycle-schema'),
FromFilesSchemaProvider::class => FromFilesSchemaProvider::config(files: [
'runtime/schema1.php',
'runtime/schema2.php',
]),
]);

$schema = new Schema($pipeline->read());
```

The `SimpleCacheSchemaProvider` requires an implementation of `Psr\SimpleCache\CacheInterface`, which must be defined
in your container. It uses this interface to retrieve and store the schema array. Alternatively, you can use the
`Cycle\Schema\Provider\PhpFileSchemaProvider`, which can save the schema to a PHP file.

### Building DB schema from different providers

To merge schema parts obtained from different providers, use `Cycle\Schema\Provider\MergeSchemaProvider`.

```php
use Cycle\ORM\Schema;
use Cycle\Schema\Provider\FromFilesSchemaProvider;
use Cycle\Schema\Provider\SimpleCacheSchemaProvider;
use Cycle\Schema\Provider\MergeSchemaProvider;
use Cycle\Schema\Provider\Support\SchemaProviderPipeline;

$pipeline = (new SchemaProviderPipeline($container))->withConfig([
SimpleCacheSchemaProvider::class => SimpleCacheSchemaProvider::config(key: 'cycle-schema'),
MergeSchemaProvider::class => [
FromFilesSchemaProvider::class => FromFilesSchemaProvider::config(files: [
'runtime/schema1.php',
'runtime/schema2.php',
]),
CustomSchemaProvider::class => ['some' => 'config'],
],
]);

$schema = new Schema($pipeline->read());
```
