Bad IDE experience with ReScript 12

[DZakh]

I currently mostly work on two projects: HyperIndex with ReScript 11 and Sury with ReScript 12 and rewatch.

If I use 1.64.0 I get:

• In HyperIndex it instantly crashes 3 times and stops working afterwards. Usually happens the first time I switch the tab
• In Sury it always jumps when I save the changes, but it's bearable

So to work on HyperIndex I switch to 1.62.0, but:

• In HyperIndex it works perfectly good
• Works good, but formatting and autocomplete are broken

So for ReScript v12 I don't have a good option.

As a repro you can try working in the file: https://github.com/DZakh/sury/blob/main/packages/sury/src/Sury.res

So, to sum up, 1.64.0 broke v11, but works (with caveats) for v12.
1.62.0 - v11 works well, Sury (v12) it's (partly) broken

Is that correct?

Working through the stability of the extension for v12 will be focus now soon. But it worries me if v11 is broken in the latest version, partly or not.

[DZakh]

Is that correct?

Yes

I think the main broken thing in 1.64.0 for ReScript v11 is that it crashes 3 times when switching between projects and requires you to reload IDE to make it work again.

What does the crash say?

Well, probably this is not an issue many people will have, since these are files without a rescript.json file. But at least it used to work with 1.62.0

[zth]

I've actually kind of fixed this, but not released stable yet: accb287

But I don't understand why this has started happening.

[zth]

@DZakh for your "jumping editor" issue, can you confirm it still happens even if you disable all other extensions but ReScript?

[DZakh]

I'll try, but it doesn't happen with 1.62.0

[zth]

@DZakh could you also try the vsix from the latest action run and see if that fixes the crashes?

Do you mean to try with the master version?
