How to use --grammar and use-grammars

[CptPotato]

So I tried using the new --grammar option introduced in #1659. The PR mentions that it's possible to select which grammars to fetch/build by adding something like this to the top of languages.toml:

use-grammars = { only = [ "rust", "markdown" ] }

I tried doing that but it doesn't seem to work. I'm getting this error when calling hx --grammar build or fetch:

Error: data did not match any variant of untagged enum GrammarSelection for key 'use-grammars'

---

If I change it to this, the build and fetch commands seem to work:

use-grammars = [ "rust", "markdown" ]

So.. how do you actually use the use-grammars config correctly? There doesn't seem to be any info in the docs, yet.

It looks like there was a bug was preventing the use-grammars value from being deserialized as expected (see #1818).

As for docs, the doc publishing setup was recently changed to show the latest release docs and master docs separately (see #1783), so the new documentation for this lives here.

Thanks for the quick reply! this pretty much answers my question.

Also good to know that the docs are split now 👍
