Rescript compilation issue on fresh install in Windows

[jackkilgore]

Hiya, I'm trying to run a CI workflow that uses elementary in the pipeline. On a fresh install of elementary on Windows I get a compilation error when running "npm run re:build".

The gentype files in rescript are improperly normalizing the paths of curry.js":

When cloning elementary, src/Reconciler.gen.ts and src/NodeRepr.gen.ts correctly have the import statement:
import * as Curry__Es6Import from 'rescript/lib/es6/curry.js';

On running "npm run re:build", rescript improperly reformats the import statements to:
import * as Curry__Es6Import from 'rescript/lib/es6\curry.js';
It adds a backslash, only when building on Windows. It then attempts to build and fail.

This does not happen to any other files besides NodeRepr.gen.ts and Reconciler.gen.ts

When running locally, I just need to manually fix it once and then I'm good to go. However, now that I'm using CI, this gets a lot more nasty to solve.

I did some research and it seems to be an unaddressed problem by the rescript maintainers:
rescript-lang/rescript#6331

I'm not sure how to fix it. Do you think you can remove the use of curry statements to avoid this problem unaddressed by the rescript developers?

Thanks!

Hey Jack, apologies for the delay here– I remember this conversation though, chatted with Can a bit about it on Discord. You're right that the issue there is ultimately with Rescript, and I'm bummed to see it's still unaddressed upstream.

As a general solution, I would say that (1) ideally you don't need to be building the javascript packages yourself, so if we can find a way to move you off of that workflow, that would be ideal. But (2) even if you need to build the package, you don't have to do it on Windows. In a CI workflow you could feasibly run the npm run build steps on a Linux machine, zip up the build artifacts, and then in a subsequent CI step that does run on windows, fetch those zipped artifacts and use them.

How does that sound?
