I've been wanting an updated version of rocup for a while, so I finally created one.
https://github.com/imclerran/rocup

Full credit to @Krzysztof Kielak's original rocup as inspiration - this is a totally revamped rocup with the zig based compiler first-class.

usage: rocup [alpha4 | latest | <hash> | <path> | +N | -N | list | remove <ver> | prune <N>]

Install it with:

curl -fsSL https://raw.githubusercontent.com/imclerran/rocup/main/install.sh | sh

Cool, but watch out, you have a dangerous typo in the GitHub address!

Double checked the markdown link for typos as well :sweat_smile:

Just added Windows support as well.

Windows usage is the same, with the exception of alpha4-rolling, which does not have a Windows binary, and so that command is dropped from the Windows version.

Installed with:

iwr -useb https://raw.githubusercontent.com/imclerran/rocup/main/install.ps1 | iex

rocup follows the created_at ordering returned by https://api.github.com/repos/roc-lang/nightlies/releases.

The issue is that the releases' created_at dates are not as reliable as their published_at.

❯ ruby -rjson -ropen-uri -e 'JSON.parse(URI.open("https://api.github.com/repos/roc-lang/nightlies/releases?per_page=15&page=1").read).each { |r| puts [r["tag_name"], "created_at=#{r["created_at"]}", "published_at=#{r["published_at"]}"].join("  ") }'

So either:
1) roc fixes the created_at to match the published_at and tag_name
2) rocup fetches a page large enough (60 for 2 months?) to do a published_at reordering

Note that there is no ?sort=published_at query available in the release REST API https://docs.github.com/en/rest/releases/releases?apiVersion=2022-11-28

Thanks for looking into this @Romain Lepert :)
The created_at is based on commits in the nightlies repo, not the main roc repo. I would prefer to avoid creating meaningless commits or tags on the nightlies repo to "fix" the created_at dates.
