bug#73978: 31.0.50; Text syntax applied on too many things in tsx-ts-mode

X-Debbugs-CC: theo@thornhill.no

In tsx-ts-mode we use this query to apply syntax properties:


(defvar tsx-ts--s-p-query
  (when (treesit-available-p)
    (treesit-query-compile 'tsx
                           '(((regex pattern: (regex_pattern) @regexp))
                             ((variable_declarator value: (jsx_element) @jsx))
                             ((assignment_expression right: (jsx_element) @jsx))
                             ((arguments (jsx_element) @jsx))
                             ((parenthesized_expression (jsx_element) @jsx))
                             ((return_statement (jsx_element) @jsx))))))


And then in tsx-ts--syntax-propertize-captures we mark everything
enclosed by the captured jsx_element nodes in text fences.

Then for the following code

<button onClick={() => {
  func();
  return true;
}}>
  Text
  {func();}
</button>

All the func() and other code will be considered text because the whole
jsx tag (<button>...</button>) are wrapped in string fences. Theo,
what’s the original intention for marking jsx_elements as text? Can we
only mark jsx_text as string?

Ping! Theo, can you answer Yuan's questions?

I’ve been using my local fix at work for a while now and it seems to work fine. I’ll make a patch and apply in a few days.

Did you have an opportunity to install such a patch?

Hey sorry, I haven’t applied the patch. Actually, I want to ask you a question before I do: is there a way to mark a single character in buffer in string syntax? The only way I’m aware of is to mark string delimiter syntax to the start and end of the string, but that doesn’t work for a single character.

Take the following snippet as an example:

<button>a<button>

I want to apply string syntax to “a”.

If there’s no such way, I guess just not applying the string syntax in such case is also an option.

There's a syntax-table text property, see the node "Syntax Properties"
in the ELisp manual.  Would that do the job?
