Ammonite-repl (in core) installs problematic experimental version that doesn't work

[TJC]

Hi,
I'm not sure if this is the right place to report this issue, but I'm taking my best shot. Let me know if this should get reported elsewhere?

Homebrew core contains https://github.com/Homebrew/homebrew-core/blob/master/Formula/ammonite-repl.rb

Fairly recently, this was updated to start using a branch of Ammonite that uses Scala 3 as a base, rather than Scala 2.13.
Unfortunately, there is a significant bug in this version, which totally breaks Ammonite's shell scripting.

See com-lihaoyi/Ammonite#1190

Ideally, Ammonite in Homebrew should be reverted to the stable version, ie. 2.13-2.4.0, instead of 3.0-2.4.0

Can that be done?

Sounds fine to me -- just open a pull request. Bump the formula's revision to make sure existing users get the updated version of the formula when they brew upgrade. (grep revision for examples.)

Thanks for the quick reply!
I've created Homebrew/homebrew-core#84985 to do this. It looks OK to me, and passes tests, but this is the first time I've made a PR against Homebrew.

This has now been fixed upstream in Ammonite, so after the next stable release there, I think the Homebrew recipe could be updated to switch to the scala-3 stream.
