I spent a week working on regression tests & metadata guarantees on the YINI config/settings parser

Source: Dev.to

Overview

I just wanted to share a small win from my side project. I’ve been working on YINI, a configuration format with a TypeScript parser (including spec, grammar, etc.).

Recent Release: v1.3.3‑beta

• No new features were added.
• The focus was on building proper smoke and regression tests around the parser.
• New tests parse a couple of large production‑style configurations (one corporate SaaS setup and one high‑security/distributed setup) and verify that:
  • The output is identical in default mode, strict mode, and strict + metadata mode.
  • Metadata and diagnostics behave correctly for both valid and broken inputs.

The API remained unchanged; the release is about making the project more predictable, safer to depend on, and easier to evolve.

Why This Matters

• Improves reliability for developers who depend on YINI.
• Lays the groundwork for the next big step: expanding and refactoring the YINI CLI to be more robust and production‑ready.

Get Involved

If you’re building developer tools, working with config‑heavy systems, or dealing with many INI/JSON/XML files, you might find YINI interesting:

I’d really appreciate any real‑world testing or feedback. Good luck with your own side projects—they often turn out to be more work than they first appear!
