Svelte 5 ecosystem CI is failing

[benmccann]

Describe the bug

I don't understand why this is failing though

I should also note that TemplateNode is declared in the types twice. Once in the root of the types as a non-exported type and once exported from 'svelte/types/compiler/interfaces'

Reproduction

Upgrade enhanced-img to the latest Svelte 5 and run pnpm check

Logs

No response

System Info

`main`

Severity

blocking an upgrade

Additional Information

Should have been fixed with sveltejs/svelte#12292, but for some reason it seems not to be working

There's no real good to make this work other than to keep exposing the old AST types through that never-meant-to-be-public interface. And I'm not sure if that is the right solution. I'd rather switch to redeclaring those types within enhanced image for the time being, and once it has a peer dependency of Svelte 5 minimum you can switch to a) the modern parse output b) use the types exported along with it.

[benmccann]

Ah, we can switch to modern parse output. I didn't realize until just the other day that there's a flag for that and it can return two different AST.

It's probably a bit late in the game, but I would have made it version: 5 so that we don't have moreModern: true if we switch to some other implementation in the future.

[dummdidumm]

The old AST will probably be gone in 6, and I sure don't hope we already have changes by then, so if we ever have another AST we can just use modern again

[benmccann]

Oh yeah, good call. Maybe we should deprecate the non-modern one now.

[dummdidumm]

I mean, it is deprecated. It's just for a seamless switch that we default to the old one

[benmccann]

It's not showing deprecated for me. I upgraded the project to Svelte 5, but don't see any indication in the IDE.
