Hi!
It seems that, since recently, Emacs has started getting confused in
tsx-ts-mode. For instance, text motions appear to be wrong.
Reproduction steps:
1. Insert the following into a tsx-ts-mode buffer:
--8<---------------cut here---------------start------------->8---
function F() {
return (
Delete
);
}
--8<---------------cut here---------------end--------------->8---
2. Install tree-sitter-tsx v0.23.2
3. M-x tsx-ts-mode RET
3. M-: (goto-char 39) RET (somewhere in the middle of "Delete")
4. M-b
5. Observe that point is not at the start of "Delete"
Following that, alter to be and hit RET at the start
of "Delete", at this point you should see:
--8<---------------cut here---------------start------------->8---
function F() {
return (
Delete
);
}
--8<---------------cut here---------------end--------------->8---
This is unusual.
In addition, I just noticed one more thing; make a new file containing:
--8<---------------cut here---------------start------------->8---
function F() {
return (
Delete
);
}
--8<---------------cut here---------------end--------------->8---
Navigate to the start of "Delete", run M-x treesit-explore RET, hit RET
and tell the explorer to highlight the jsx_text corresponding to
"Delete", you should see that the region highlighted is not aligned with
the end of the word "Delete", and, in turn, all subsequent AST nodes are
mispositioned too. Typing again fixes this issue. It seems that the
buffer needs to be freshly-started for this to happen for some reason.
I do not have any idea why this might be happening.
Thanks in advance, and happy holidays!
