Niclas Ahden (Dec 23 2025 at 20:13): Niclas Ahden (Dec 23 2025 at 20:13):Does the new compiler support modules and/or packages? I'm extracting a few Roc packages from the projects I've been working on. They're using the Rust compiler, but I thought it'd be fun to use the new compiler if possible. I tried but it seems it doesn't work yet, but I thought I'd ask!
Richard Feldman (Dec 23 2025 at 21:02):modules yes, packages not yet! :smile:
Niclas Ahden (Dec 23 2025 at 21:06):OK, I'll use the Rust compiler for now and it'll be a nice exercise later to convert them :)

I'm confused on what a package is vs what a module is
Hannes (Dec 24 2025 at 00:37):You can import code you wrote but not code other people wrote :)
nandi (Dec 24 2025 at 00:40):What does that look like in the source though? like whats the difference between import syntax?
Luke Boswell (Dec 24 2025 at 02:59):A package is a collection of modules, you can import them from a URL. A platform is just a special package, that also includes the prebuilt binaries and a platform module.
Luke Boswell (Dec 24 2025 at 02:59):You can bundle the .roc files (modules) using thr cli, roc bundle
Luke Boswell (Dec 24 2025 at 03:00):here is an example package from the snapshots https://github.com/roc-lang/roc/tree/main/test/snapshots/plume_package
Luke Boswell (Dec 24 2025 at 03:03):I think we still have a few issues lurking around using packages. I've just finished fixing enough to get basic wasm platforms working. I'd like to get a simple package working soon too, just to help flush out the issues. If anyone wants to poke at that and report bugs, that would be super
Luke Boswell (Dec 24 2025 at 03:05):@Richard Feldman that package includes a module using our older module header syntax... I am surprised that's passing in CI tbh. I expected it to throw an error on the older syntax. Am I correct i that?
nandi (Dec 24 2025 at 03:06):Awesome thanks for the info. Some of this is a bit intimidating wrapping my head around since I'm so new to the project, but I'm having a blast learning everything
Luke Boswell (Dec 24 2025 at 03:07):Ah, I see it's got the error in there. We should fix that to use the proper syntax I thjnk.
Luke Boswell (Dec 24 2025 at 03:08):Also we could probably include multiple files. I remember this was one of the first snapshots we added to check our package syntax for parsing and canonicalisation, but now we should probably upgrade this to be a more realistic package so we can c
validate features higher in the stack
Luke Boswell (Dec 24 2025 at 03:09):Sorry for spelling and grammar here, on my phone and this keyboard is challenging
Luke Boswell (Dec 24 2025 at 03:10):It's been on my todo list to make a really basic package with a bundled release and check its all working.
