[Netail]

.yaml / .yml files are widely used in the frontend ecosystem (Github workflows, configs, helm, files) which would a nice addition to supported languages.

Linked issue, for progress tracking; #2365

Hi! Would you be interested in working on this?

[ematipico]

We already have another person that showed interest on Discord

[Netail]

Seems like @castarco showed interest indeed

Hi @Netail , ping me on Discord :) , we can discuss it.

I didn't start working on it yet, so I don't want to stop anyone from picking it up. But I'd like to coordinate so we don't stall this topic by acident.

I have never worked with Rust before, so it's all yours :)

Wouldn't mind trying to help here as well! Not a Rust pro, but I can dabble

I would like to see the configuration file (biome.json) support (a safe subset of¹) YAML syntax. YAML is a much more friendly format for writing configuration.

It seems the YAML parser is already implemented, so a good test for the parser would be to read this configuration.

Footnotes

1. basically, only literals with JSON-equivalents (eg no date-times), and no custom types (ie no !foo directives). Optionally support references (ie qux: &foo bar, baz: *foo) ↩
