Subject: 30.0.50; Font lock rule conflict in js-ts-mode at level 4
Date: Thu, 7 Dec 2023 11:07:53 +0100

Hi !

Hi !

I have noticed a font coloration issue in js-ts-mode when setting the 
treesit font lock level to 4: JSX attributes color is not the same than 
at level 3.
There should have a conflict between rules for "property_identifier" 
treesit type. The feature that triggers the conflict is "property" (of 
the level 4).

You can reproduce the issue by following these steps:
- M-: (setq treesit-font-lock-level 4)
- M-x js-ts-mode on a JSX buffer

Note that the bug already exists in Emacs 29.1.

Thanks !

Loïc

The attached patch seems to fix that.

But it removes a function added by Yuan in e78e69b33189, while 
reshuffling the highlights to reorder priorities.

Yuan, do you remember why you did it that way back then? Perhaps I'm 
missing some other conflict.

For a method invocation like obj.fn(), the "fn" should be fontified in 
function-call-face. However, "fn" is a property_identifier in the parse 
tree, so it would be fontified in property-use-face by the property 
feature. The predicate in the property feature makes sure we skip 
properties that are function invocations. And down the line in function 
feature, you'll see

(call_expression
      function: [(identifier) @font-lock-function-call-face
                 (member_expression
                  property:
                  (property_identifier) @font-lock-function-call-face)])

Here, the property_identifier is fontified in function-call-face.

Thanks. So the patch I sent should also cover this, right?

It moves the 'property' feature to below 'function'. And below 'jsx', 
which fixes the problem reported in this bug.

Ah, right. In that case, I don't have anything else to add.
