About YINI

YINI is a new configuration format (formalized in 2025) designed for clarity, easy nesting, and predictable validation.

The format’s syntax and behavior are defined in the YINI Specification, currently at Version 1.0 — Candidate Release.

YINI was created and is maintained by Marko K. Seppänen as an open-source project under the YINI-lang organization on GitHub. The specification, tooling, and ecosystem are actively evolving toward the first stable release.

YINI is a practical rethink of classic INI: the same friendly feel, but with real structure—sections, arrays, objects, and clear rules—while staying easy to read and write.
