INI vs TOML vs YAML: what to use for configs
Compare INI, TOML, and YAML for configuration: types, comments, nesting, readability, and when conversion to JSON is safer for automation.
YAML comments (#) pitfalls
Troubleshoot YAML comments (#) pitfalls with a stable workflow: validate YAML, fix the minimal block, and re-validate before conversion (no upload).
TL;DR: Validate locally, pinpoint the failing spot, apply the minimal fix, then validate again.
Fast no-upload workflow
- Validate the input (strict rules, correct encoding, correct delimiter/quotes).
- Locate the exact position/line reported by the parser or validator.
- Fix the smallest broken part (often a quote, escape, delimiter, or a truncated copy/paste).
- Re-validate and only then convert/export.
