While the core Robotlegs developers do some preparatory undercover work on Robotlegs 2, some adventurous Robotlegs users have decided to take things into their own hands and start building their own ideal frameworks. I think this is great. The best ideas will almost certainly make their way back into RL2 in some shape or form.
Some things that these framework experiments will probably have in common:
Support for the Mediator pattern
Support for the Command pattern
Display-list processing (auto-wire)
Dependency Injection through Swiftsuspenders
The first of these is Boiler by Rasheed Abdul-Aziz (@squeedee): http://devblog.vworkapp.com/post/8538689880/r
Please have a look and give Squeedee some feedback. Some things that I like: convention over configuration, avoiding inheritance, the name!
