Forwarding to the bug tracker.

Thanks for telling us.

The question why we changed the signature in Emacs 30 still stands.

I think it may be a bug (accidentally change code?) so I report it here.

Emacs 29.3 treesit-parser-list only accepts one parameter (i.e. BUFFER),
but the treesit-parser-list on the latest Master Branch doesn't change,
accepting three optional parameters.

According to "git log", it was a deliberate change.

Yuan, why did we change the signature, and why isn't tyhis called out
in NEWS?

I believe we only changed the signature from one optional arg to three optional args, on master. Treesit-parser-list never had one mandatory arg.

We changed the signature to three optional args to a) allow users to get parsers for a specific language, and b) allow users to get parsers with a specific tag. Parser tags are used by local parsers.

I should have added a NEWS entry, but apparently I forgot :-) Sorry about that. I’ll add it, along with other functions that I said I’ll wait a bit more before documenting (it’s about time).

Ping! Could you please do these documentation changes now?

Thanks.

My pleasure. It just happens today I finally got a day where I can sit down and write some code. I updated manual and news entries. There’s one thing though, I couldn’t find a good way to avoid using variables (which starts with lowercase) at the beginning of sentences. I don’t know how do you feel about having lower case letter at the beginning of sentences. If you have good tips on avoiding them I’m happy to apply it to all the occurrences in the new manual entries I wrote.
