ruby 3.0

[glaszig]

i have a sizable production app running with ruby 3.0. a runtime upgrade is on the roadmap but not near which i think is true for many real-life applications. but i’d also like to use plumb.

would you accept compatibility PRs for eol ruby versions? from what i’ve seen changes would only apply to syntax sugar anyway.

Hey, thanks! yes, I'd gladly accept that PR. Perhaps you can also add 3.0 to the test matrix in .github/workflows/ruby.yml

Re. using Plumb in your project, thanks again but I hope you're aware this gem is still WiP. Having said that, I'm sure we'll get useful feedback from your use case.

Also probably point your project to this repo (or your fork), as the published gem will be behind main for a while.
