Patternslib and mockup are compatible and integrated with each other. The things plone core is using from patternslib are registry, scanner and logging AFAIK.
This is done. modal pattern was the only name clash I believe.
Nothing has been moved to patternslib yet and we haven't identified any patterns to move to patternslib from mockup yet either.
It's a long term goal and general guidance for how to understand the two libraries. There are plenty of other things to do and fix so no one has focused on this.
I was just following the mockup documentation..and while bundling up 'make bundle-widgets' i am getting errors, something like this--
SyntaxError: Duplicate data property in object literal not allowed in strict mode
Warning: Task "bundle-widgets" not found. Use --force to continue.
Aborted due to warnings.
make: *** [bundle-widgets] Error 3
