svelte-check isn't used for formatting.

My bad it was the wrong release tag 😄

The version that no longer works is this one (the most recent):
https://github.com/sveltejs/language-tools/releases/tag/extensions-108.0.0

Reproduction:
I have a basic svelte component file, and when I switch to the latest version 108.0.0 there's no formatting, but when I switch back to the previous version it works and the file is formatted like always.

I can't reproduce this. Please provide a github repository that reproduces this issue.

Experiencing the same bug since yesterday (latest release). Just opened a very basic empty .svelte file. Auto-formatting does currently not work.

Reverting to v107.13.0 and auto-formatting works

[dummdidumm]

Can someone please provide an actual reproduction instead of just saying it doesn't work? As I said I can't reproduce this.

It has to do with the bump to using prettier version 3 by default now, I'm pretty sure about that, but I need a reproducible to get to the bottom of this

[yassinrais]

im working on it :) sorry for late

@yassinrais if it helps you : I had the same issue with prettier version 2, updating to version 3 solved the problem
