@ericonr

linter complains:

revision should be set to 1 on update

But I set the revision to 2.

How come?

xlint didn't complain before I pushed the pr here.

It's the same thing as explained in #34180 (comment)

We only need revisions when the version remains the same. Once the version changes, we reset the revision.

I'm currently testing this version of tree-sitter with neovim, seems to work perfectly.

How are you testing tree-sitter?

Could you share a tip? :)

How are you testing tree-sitter?

I use tree-sitter indirectly because I use neovim with a few plugins that rely on its functionality. If tree-sitter broke, tons of things about my editor would be broken. Unfortunately I don't have a great way to test it directly. Sorry :(
