Question on toml

[simonjwright]

The gprbuild toml includes

[origin."case(os)".linux."case(host-arch)".aarch64]
url = "https://github.com/reznikmm/GNAT-FSF-builds/releases/download/gprbuild-22.0.0-1/gprbuild-aarch64-linux-22.0.0-1.tar.gz"
hashes = ["sha256:19730c52a46c32f0f2f4a295418762a0e22645ef663f2a1c1f1b77ea71a4cee4"]

How did you get alr publish to do this? or was it a post-publish edit?

I put this in my alire.toml, which is carried through the publication process and, I think, has the same effect.

[available."case(os)".macos."case(host-arch)"]
"aarch64" = true
"..." = false

I didn't do alr publish. I copy/pasted this from gnat_native-12.2.1.toml, gprbuild-22.0.1.toml of the community index. I think, your method should work.
