I've been trying to tweak the font-locking for tree-sitter in js/ts-mode, and I'm still struggling with the template strings. Is there a way to _disable_ font-locking for smaller ranges? Let's say you have this string: ``` `Some string with ${5+5} many template substitutions ${foo().bar().baz()}`; ``` This string will match something like: ``` (template_string (template_substitution) :*) ``` If you use this as a query: ``` (template_string) @font-lock-string-face ``` Everything inside the string is in string-face. If you add ``` (template_substitution "${" @font-lock-constant-face (_) "}" @font-lock-constant-face) ``` You get font-locking in the ranges inside the squigglies, as expected. However, if there isn't defined any rules for say, "(), . []" etc, the template_string capture will bleed into the substitution, because its range suggests it should. It would be nice to say something like: ``` (defvar fonts () (treesit-font-lock-rules :language 'tsx :override t :feature 'basic '((template_string (_):* @disabled) @font-lock-string-face (template_substitution ["${" "}"] @font-lock-constant-face))) ``` to ensure that whatever is inside the wildcard match will _not_ be considered for the string face, but whatever is still inside the bigger range will. Is this currently possible? If not, is it possible to add? I guess I could make a function that would remove the range, but that seems fiddly and error prone. I've tried fiddling with the :feature flag in 'treesit-font-lock-rules', but I never found a combination that did what I wanted.

Do you not want to font-lock what’s inside a substitution? I’m not exactly sure what result you want to archive. If you don’t want font-lock in substitutions, you can put > '((template_string) @font-lock-string-face > (template_substitution ["${" "}"] @font-lock-constant-face)) After all other queries, and mark these two with :override t. That should do it. Also, when I was browsing tsx’s grammar file, I didn’t find definition of template_substitution at all. That means at least some part of js and tsx’s grammar are not interchangeable. Yuan ^ permalink raw reply [flat|nested] 14+ messages in thread

Inner template_substitution > If it's useful, I believe the reason why the queries you were using didn't work was because you were using the alternation which only allows for selecting a single option. This should work, regardless of the order: (template_substitution "${" @font-lock-constant-face "}" @font-lock-constant-face) @default (escape_sequence) @font-lock-constant-face (template_string) @font-lock-string-face However, I am unsure how to address potentially nested template substitutions. Perhaps a function could assist in that. Trey ^ permalink raw reply [flat|nested] 14+ messages in thread
