🚀 YINI Parser v1.3.0-beta – Smarter Options, Safer Metadata, and New Controls

#typescript #node #opensource

I've just released yini-parser v1.3.0-beta 🎉 (Node package) - a big step forward for ergonomics, diagnostics, and developer experience when working with YINI configuration format, the human-friendly configuration format inspired by INI but with modern clarity.

This release focuses on cleaner public APIs, new output controls, and better tooling around metadata and CI.

✨ What's New

🐛 Fixed

Fixed a bug where buildResultMetadata(..) could occasionally produce an undefined error.

🔄 Renamed (Breaking API Changes)

To make public types more ergonomic for end-users, several interfaces were renamed:

AllUserOptions → ParseOptions
PrimaryUserParams → BasicOptions
OnDuplicateKey → DuplicateKeyPolicy

This makes names shorter, more consistent, and closer to their intent.

📖 Clarified

The strictMode parameter in TSDoc has been clarified: It defines the baseline ruleset (true = strict, false = lenient). Rule-specific options (e.g., treatEmptyValueAsNull, onDuplicateKey) may override the baseline. When overrides are applied, the effective mode becomes custom.

🆕 New Features

DocumentTerminatorRule and EmptyValueRule: new user-facing parsing rule value types.
quiet option:
- Only prints errors to the console.
- Warnings, notices, etc. are suppressed.
- Diagnostics are still captured in metadata.
silent option:
- Suppresses all console output, even errors.
- Programmatic callers should use metadata; CLI users should rely on the exit code.
throwOnError option:
- true (default): parser throws on parse errors.
- false: errors are reported via diagnostics without throwing.
- ⚠️ Planned change: next release will switch the default to false.
- ✅ Action: set throwOnError: true to keep current behavior, or throwOnError: false to adopt the upcoming behavior.

📊 Metadata Improvements

Added effectiveMode inside meta.diagnostics.effectiveOptions.
Metadata bumped to v1.1.1.
Fields strictMode and effectiveOptions now correctly reflect when rules override the initial mode.

The resultet metadata looks like this:

    "meta": {
        "parserVersion": "1.3.0-beta",
        "mode": "strict",
        "totalErrors": 0,

                "User2.PrefsOfUser2",
                "User2.PrefsOfUser2.DeepSection",
                "User2.PrefsOfUser2.DeepSection.DeeperSection",
                "User2.PrefsOfUser2.DeepSection.DeeperSection.YetDeeperSection"
            ]
        },
        "metaSchemaVersion": "1.1.1"
    }

🛠️ CI & Tooling

The repo now runs stronger checks on every PR & release:

Security: CodeQL, npm audit, lockfile-lint, Gitleaks (SARIF), Semgrep (SARIF).
Grammar drift check: Ensures ANTLR-generated sources are committed.
Regression tests: Node/OS matrix coverage.
Releases: npm publish with provenance (tag-driven).

💬 Other

Parser summary logic and messages have been updated for clearer output.
