A wild idea appears... what if you could use JBang with JRuby as a complete Rails command line... no JVM or JRuby installation required?
jbang rails@jruby new blog
cd blog
jbang rails@jruby generate scaffold ...
It just needs some tweaks to work. Interested?
Exciting demonstration of how fast JRuby can really be when you sweep away some of the metaprogramming layers of a typical Rails application... even when it already handles Rails HTML requests 2x faster than CRuby! Looking forward to seeing more about Roundhouse.
I've started a project to collaboratively build templates for JRuby on Rails! So far there's just the bare minimum Rails 8.0 template I posted about earlier this week. Rails template experts are desperately needed, as well as anyone who has an idea for JRuby on Rails templates!
