I could not figure out how to test this because the globals are different for Svelte4 and Svelte5. Once I created the expected files for Svelte5, but there are too many additional lines. Any suggestions?

ota-meshi · 2023-11-15T01:06:34Z

Wow! I noticed this PR after opening #426. This PR seems to be a little more advanced than #426 as type information for runes is added.

I could not figure out how to test this because the globals are different for Svelte4 and Svelte5. Once I created the expected files for Svelte5, but there are too many additional lines. Any suggestions?

In #426, the idea is to explicitly opt in to runes mode using an option to make it work.

In #426, the idea is to explicitly opt in to runes mode using an option to make it work.

From the user's point of view, using Svelte5 = being able to use runes, so if there is a way to not force users to configure it, that would be good.

About test, how about to extract variables part and prepare only this part for Svelte4 and Svelte5 separately.
Then we can prevent to make duplicated expected files.

https://github.com/sveltejs/svelte-eslint-parser/pull/425/files#diff-8907e5126cad5dd0dd35d0025fdd3086e01a29d3cb72fd9bb5f37b6352ba9048R3-R52

One question, my understanding is that the Svelte compiler is not bundled with svelte-eslint-parser so it always uses the version installed by the user, correct?

baseballyama · 2023-11-15T01:22:52Z

I think my todo is there.

Reduce duplicated expected files
Add tests for runes types
Handle $derived (I need to understand about this issue at first)

baseballyama · 2023-11-15T01:25:42Z

Oh but your PR supports .svelte.js files.
So somehow we need to combine these PRs.

ota-meshi · 2023-11-15T01:26:38Z

One question, my understanding is that the Svelte compiler is not bundled with svelte-eslint-parser so it always uses the version installed by the user, correct?

Yeah, we specifying svelte in peerDependencies and peerDependenciesMeta, so I expect the user to be able to use whatever version they want to use.

baseballyama · 2023-11-15T01:34:24Z

What do you think is the best way to do Next Action?

My opinion is that runes should not be configurable and should be reconize automatically by the parser, but since you are more professional in this field than me, please make a decision.
As for testing, it is possible to eliminate duplicates and I can handle that.
Regarding support for the .svelte.js file, would it be better to merge your PR after this PR is merged? Or we can collaborate on this branch and put them together as one PR, but I have no opinion here.

ota-meshi · 2023-11-15T02:24:09Z

My opinion is that runes should not be configurable and should be reconize automatically by the parser, but since you are more professional in this field than me, please make a decision.

I think we can consider what our options are after Svelte v5 is released. I believe we can remove options or even change the defaults for options.
However, it currently needs to be marked as an experimental feature, so I think it makes sense to provide it as an option for now.

would it be better to merge your PR after this PR is merged?

Yeah, I would like to change and merge #426 after this PR is merged.

ota-meshi · 2023-11-15T02:30:21Z

However, it currently needs to be marked as an experimental feature, so I think it makes sense to provide it as an option for now.

Oh, I think it's a good idea to judge by svelte version rather than using options. Installing svelte v5 means the user is explicitly using pre-release.

src/parser/globals.ts

+  "$state",
+  "$derived",
+  "$effect",
+  "$effect.pre",


Since $effect.pre is a member of $effect, I don't think it is necessary to define it here.

Suggested change

"$effect.pre",

baseballyama · 2023-11-15T15:37:48Z

Tomorrow I will add more tests for runes.

ota-meshi

It looks mostly good, but I did make one comment 😃

ota-meshi · 2023-11-17T00:33:08Z

src/parser/typescript/analyze/index.ts

+          if (
+            scopeManager.globalScope!.through.some(
+              (reference) => reference.identifier.name === svelte5Global,
+            )
+          ) {


By moving this judgment before the switch, I think we can eliminate the four same implementations.

Ohhhhh...
