Sourcemap missing any fowarded styles

[neclimdul]

The content of the map just include the base file with the @forward rule so it doesn't actual resolve any useful information.

Repo with an example.

I tried to track this down, but it was pretty hard to understand. It seems like rollup understands the full source map, sourcemapChain in getCombinedSourcemap has all the information to build the source map including the linked sheet. But then it calls getCollapsedSourcemap and that reduces the chain with this return sourcemapChain.reduce(linkMap, source); throwing away all the linked maps. I don't really understand what rollup is trying to do here or how you could coax it into giving you everything. Its also possible I'm completely on the wrong track.

Hi @neclimdul I've been taking a look into this. What I've seen is this

At this point in time, vite has been able to resolve the @forward tag and get the real code, but once the plugin calls this.getCombinedSourcemap()

rollup is using as the original code the @forward instead of the resolution, which I guess is "correct" but also you would expect rollup to resolve it too?

I'll see if I can do something, but for now, I imagine that the easiest thing for you would be to directly put the CSS in the file

When I have some more free time, I'll try to find a solution or a workaround for it. Thanks for reporting!

hey @neclimdul could you try with version 1.0.5? thanks!

@MarioCadenas, version 1.0.5 didn’t help — the issue is still there, and it’s the same with .less imported files @import "file.less"
