How can a script determine the latest Julia version and latest pre-release in CI?

How can I determine:

  • the latest stable Julia version
  • the latest Julia release
  • the latest Julia pre-release

on github?

I can do:

ufechner@ufryzen:~$ juliaup list | grep release
 release              1.11.4+0.x64.linux.gnu          
 release~x64          1.11.4+0.x64.linux.gnu          
 release~x86          1.11.4+0.x86.linux.gnu

which is already nice, but I don’t have the version number string yet.

I cannot do:

juliaup list | grep pre

This gives me only version 0.6 as pre-release.

Thanks for the link. Unfortunately it doesn’t solve my problem. I want to test with the latest release and the latest pre-release, but often both are the same, and then I don’t want to run the same job twice.

So I need to test if the pre-release is the same as the release. There is no job yet that can do that, so I have to program that myself. But I can program that only if I found a reliable way to determine the version number both of the latest release and of the latest pre-release.

Not really. I do not know how to extract the version number of the latest Julia version and the latest pre release from the .json file.

Perplexity suggested:

echo "latest=$(jq -r '.latest.version' <<< "$versions")"

which does not work, the result is empty.

This seems to work right now:

using Downloads, JSON
j = Downloads.download("https://julialang-s3.julialang.org/bin/versions.json", IOBuffer()) |> seekstart |> JSON.parse
lateststable = (keys(j) |> filter(contains(r"^[0-9]+\.[0-9]+\.[0-9]+$")) .|> VersionNumber |> sort)[end]
latestpre = (keys(j) |> filter(contains(r"^[0-9]+\.[0-9]+\.[0-9]+-")) .|> VersionNumber |> sort)[end]
