scedel/schema
=============

[](#scedelschema)

[![logo](https://raw.githubusercontent.com/ScedelLang/grammar/5f1e7572f328d657c726a2fcaeaf53d9f6863d6a/logo.svg)](https://raw.githubusercontent.com/ScedelLang/grammar/5f1e7572f328d657c726a2fcaeaf53d9f6863d6a/logo.svg)

Intermediate layer between `scedel/parser` AST and downstream packages (validator/codegen).

RFC support
-----------

[](#rfc-support)

- [Target RFC: `0.14.2`](https://github.com/ScedelLang/grammar/blob/main/RFC-Scedel-0.14.2.md)

What it provides
----------------

[](#what-it-provides)

- Recursive include loading (DFS include-first)
- Include cycle detection
- Diamond include graphs (shared canonical targets are loaded once)
- Warnings for direct duplicate includes in a single file
- Type merge (`type expr` + annotation-only declarations)
- Validator merge by `(targetType, name)` with strict structural duplicate checks
- Immutable `SchemaRepository` with types, validators, annotation trees, and document include graph

Usage
-----

[](#usage)

```
use Scedel\Parser\ParserService;
use Scedel\Schema\Infrastructure\FilesystemIncludeResolver;
use Scedel\Schema\Infrastructure\FilesystemSourceLoader;
use Scedel\Schema\RepositoryBuilder;

$builder = new RepositoryBuilder(
    new ParserService(),
    new FilesystemIncludeResolver(),
    new FilesystemSourceLoader(),
);

$repository = $builder->buildFromFile('/absolute/path/schema.scedel');
$type = $repository->getType('Post');
$validator = $repository->getValidator('String', 'noAds');
```

`buildFromString()` supports includes if `baseUri` is provided.

```
$repository = $builder->buildFromString(
    $source,
    'inline.scedel',
    'file:///absolute/path/inline.scedel',
);
```

Schema info utility
-------------------

[](#schema-info-utility)

Print human-readable schema info (version, documents/includes, types with constraints, validators, annotations):

```
php bin/describe-schema.php /absolute/path/schema.scedel
```

Include builtin types/validators in output:

```
php bin/describe-schema.php --show-builtins /absolute/path/schema.scedel
```
