> @linux4life798 Nice catch! I see that so far only CompilationDatabase and CompletionChunk expose functions in camelCase. It would be nice to change them, too, but those are decade-old APIs that I think we promise stability for, so it might not be possible.

Yep. Of course unrelated to this change, we might be able to add the snake_case equivalent binding and marking the old ones as depreciated.
