Ultimately you don’t need to know much Ruby to maintain or contribute to Homebrew. Ruby makes it very easy to write custom DSLs that don’t feel like Ruby. I didn’t really know any before working on Homebrew and it’s now my primary language.
That said, yes we have already moved away from our DSL being Turing Complete. This release drops for official taps the ability for packages to run arbitrary postinstall/uninstall/etc. Ruby in favour of DSLs and our JSON API.
This will likely get extended over time to eventually allow package definitions to themselves be in JSON.
