What is YINI configuration format?

YINI blends INI simplicity with JSON/YAML structure: explicit sections via ^ markers, no indentation, supports nests, lists, comments—strict or lenient parsing.

Does YINI require /END in all files?

No—only strict mode mandates it for explicit completeness; lenient mode allows EOF, forgiving truncations.

Is yini-parser production-ready for Node.js?

Yes, v1.5.0 enforces RC.5 spec fully, with TypeScript types, CLI tools—ideal for CLI apps, scripts, or any hand-edited configs.
