New Syntax: - define properties and parameters as class attributes directly instead of items in class attribute dicts - define commands with decorator @usercommand(...) - old syntax is still supported for now still to do (with decreasing priority): - turn parameters into descriptors (vs. creating getters/setters) - migrate all existing code to new syntax - get rid of or reduce code in metaclasses using __set_name__ and __init_subclass__ instead, including a fix for allowing py < 3.6 Change-Id: Id47e0f89c506f50c40fa518b01822c6e5bbf4e98 Reviewed-on: https://forge.frm2.tum.de/review/c/sine2020/secop/playground/+/24991 Tested-by: Jenkins Automated Tests <pedersen+jenkins@frm2.tum.de> Reviewed-by: Enrico Faulhaber <enrico.faulhaber@frm2.tum.de> Reviewed-by: Markus Zolliker <markus.zolliker@psi.ch>
