YAML is the simplest human-readable data-serialization language inspired by [StrictYAML](https://github.com/crdoconnor/strictyaml). Some YAML features are not intentionally supported.\n\n## Hydrogen Features\n- Fully decoupled data model from a representation\n- Implicit serialization style\n  * an intelligent YAML generator\n  * customizable print style\n- Explicit typing\n  * target class adapters\n\n## Unsupported YAML Features\n- Implicit typing\n- Duplicate keys\n- Explicit tags\n- Node anchors and refs\n- Flow style (except scalars and simple sequences)\n- Complex mapping keys\n- Directives\n\nSee [What YAML features does StrictYAML remove?](https://hitchdev.com/strictyaml/features-removed/) for more details.\n\nPresence of a removed feature raises an exception during parsing.\n\n## Usage\n\nMaven\n\n```xml\n\u003cdependency\u003e\n    \u003cgroupId\u003ecom.apicatalog\u003c/groupId\u003e\n    \u003cartifactId\u003ehydrogen-yaml\u003c/artifactId\u003e\n    \u003cversion\u003e0.2.1\u003c/version\u003e\n\u003c/dependency\u003e\n```\n\nGradle\n\n```gradle\ncompile group: 'com.apicatalog', name: 'hydrogen-yaml', version: '0.2.1'\n```\n\n\n## Examples\n\n```javascript\nYamlNode node = Yaml.createMappingBuilder()\n                    .add(\"key\", \"value\")\n                    .add(\"sequence\", Yaml.createSequenceBuilder()\n                                         .add(\"item\")\n                    ).build();\n     \nYaml.createWriter(OutputStream|Writer).write(YamlNode);\n```\n\n\n## Roadmap\n- [x] ~0.1 Document API~\n- [x] ~0.2 Writer API~\n- [ ] 0.3 Parser API\n- [ ] 0.5 Flow Sequence of Scalars\n- [ ] 0.6 Multi-documents\n- [ ] 0.8 Beans Binding\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffilip26%2Fhydrogen-yaml","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ffilip26%2Fhydrogen-yaml","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffilip26%2Fhydrogen-yaml/lists"}
