What's required here to get arm32 and arm64 support?

We'd need access to arm installers. If we had those, then all it would take would be to correctly map the URLs when architecture is arm{32,64} here:

https://github.com/Bogdanp/setup-racket/blob/11bb5ff19d1cd718876bc3cf8966a3fbce4354b7/src/common.ts#L32

We could also have a mode where it builds Racket from source but that would be very slow.

Thanks - I will try to setup some arm, arm64 snapshots created on the racket/racket side.

are you missing arm64 snapshots for this to work on arm64?

Yup! I've added support for the arch and guessed at what the URLs will end up being, but there don't seem to be installers for arm64 on the Utah snapshot server yet so arm64 won't work yet.

I will add snapshots for these in the next couple of days. I will keep you up-to-date.

any traction here? I guess the snapshots should be available now.

@jessealama it looks like only 32bit arm snapshots are available still: https://www.cs.utah.edu/plt/snapshots/

It looks like there are now snapshots for the M1 chips, though, so I'll have to add support for those as well.

Installers for Apple Silicon Macs are supported as of https://github.com/Bogdanp/setup-racket/pull/20/commits/94699d415b27bab4501b62f42f74b4eb8153d769 . GH Actions don't yet support Apple Silicon, though, so they aren't tested.

I'm try to use

      - uses: Bogdanp/[email protected]
        with:
          architecture: aarch64

get:

invalid arch 'aarch64'

what can I do here? Should I adjust runs-on: ubuntu-latest line?

@dannypsnl I've just pushed a fix to the master branch for that problem. However, there aren't any arm64 linux installers on the Utah snapshot server yet so even with that fix in place, this still won't work. You can only currently use either arm32 on Linux or aarch64 on macOS. However, you need to bring your own GH Actions runners, because GitHub doesn't yet have arm runners.
