--text follows this line--

I have a test function as following:

(defun treesit-context-test-query ()
  (interactive)
  (treesit-query-capture (treesit-buffer-root-node) '((if_statement consequence: (_) @context.end) @context)))


I expected this function would return all =if statement= in a java buffer.

But if I invoke it from M-x, it doesn't print anything in *Message* buffer.

If I call it from M-:(aka. eval-expression), it does print something.


Is there a bug here? If not, how should I use it correctly? Thanks.


How to reproduce:

0. install java tree-sitter parser

1. emacs -Q

2. open a java file

3. enable java-ts-mode

4. call the function interactively from M-x

You need to display the value the function returns, e.g., with
'message'.

There's no bug here.

Got it. Thanks.
Sorry for the noise, I should've tested more to make sure it's a real bug.
