About this tool
Normalises indentation, spacing and quoting by parsing the document and printing it back out. Parsing uses the CORE schema, so no custom tag can construct an object.
Limitations
- Formatting round-trips through a parse, so comments are not preserved. YAML comments live outside the data model.
Questions
- My comments disappeared.
- Comments are not part of the parsed document, so a round trip through the parser loses them. That is inherent to reformatting this way.
