README

Switon's strict YAML subset parser and placeholder resolver for predictable config documents.

Highlights

• Strict YAML subset: only the supported Switon YAML features are parsed.
• Single-step read: YAML can be parsed and interpolated at once.
• Predictable failures: parse errors are reported clearly.
• Config-friendly output: the result is a plain PHP array for config loading.

Installation

composer require switon/yaml

Quick Start

use Switon\Core\Attribute\Autowired;
use Switon\Yaml\YamlReaderInterface;

class ConfigService
{
    #[Autowired] protected YamlReaderInterface $yamlReader;

    public function load(string $yaml): array
    {
        return $this->yamlReader->read($yaml, ['APP_ENV' => 'prod']);
    }
}
