I can't reproduce this with any .go files I have laying around. Can you share one that reproduces the issue?

Is the tree-sitter-go shared library file you're using the latest and most up to date one?

What is the version of tree-sitter? If it's not the latest, can you try the latest and see if that helps?

Also, and just to be on the safe side, are you able to reproduce this with emacs -Q?

That version was released 2 years ago.  Maybe go-ts-mode.el relies on
some newer functionality, or on some bug that was fixed since then?

tree-sitter-go and a bunch of other grammars have dropped the ball of versioning, I think (some don't even try to version properly...). Since then there have plenty of changes, but it's stayed at the same version with no new tags. Anything packaging based on the tags of those repositories is going to be wildly out of date.

You can try using `M-x treesit-install-language-grammar` to install the go grammar, which will get the latest and greatest.

If I had to guess what triggers the error, it's probably the (iota) match which seems to have been added Jan 5, 2022. You can try removing that from go-ts-mode and seeing if it fixes the issue for you (although maybe that will fix the current problem but reveal a bunch more...all of which will be easily resolved by using a more up to date grammar). I'll try to get that old version installed myself and see.

I think java-ts-mode and some others have a helper that checks which queries are supported by testing them, I can make a patch for that if that's the direction we want to go.

I can reproduce this with the latest tagged tree-sitter-go version (v0.19.1 released on on Mar 3, 2021). I've attached a patch fixing it (i.e. go-ts-mode now runs and highlights), if we decide to support those older versions. Hopefully I didn't commit any elisp sins.

Please give it a try if you can, Jimmy. I still recommend that you upgrade to the latest tree-sitter-go (i.e. from the tip of the develop branch) yourself because v0.19.1 has other problems (some valid code can be highlighted as error if using the highest treesit-font-lock-level). And I would recommend that for all of the tree-sitter grammars.

It might be better to use treesit-query-string instead, see

Thanks.

Maybe I'm missing something, but doesn't treesit-query-string with an empty string do nothing and always error, since it queries on whatever string you pass in?

In that case, wouldn't using treesit-query-capture directly be the best? I don't understand why it's not from reading that thread. If it isn't, then treesit-query-validate is the only option, right?

It would return nil, not error (querying an empty buffer). And we should 
be checking for error.

This is the part that java-ts-mode--string-highlight-helper got right, BTW.

go-ts-mode--iota-query-supported-p in your patch relies on the condition 
that the file, at the time the mode is enabled, already contains at 
least one "iota" node.

> In that case, wouldn't using treesit-query-capture directly be the best? I don't understand why it's not from reading that thread. If it isn't, then treesit-query-validate is the only option, right?

treesit-query-validate pops a new buffer interactively in the case of 
failure, so it's not something we should use here.

Sorry, I was operating under false assumptions and somehow convinced myself that treesit-query-string with an empty string returning nil meant the query wasn't supported, hence me thinking it achieved nothing. I am no longer under such delusions :).

Good point. I've attached a patch using treesit-query-string with an empty string. It now works properly when iota is missing but inserted later.

Thanks! I've pushed this to emacs-29, so the bug can be closed.

Stylistically, I think I prefer the original way (with condition-case), 
but we'll have plenty of time to refine this on master later.
