- rework xotcl-core chat machinery to return its responses through JSON and include information about active users - depend on xowiki instead of xotcl-core only - exploit xowiki "Comet" server push implementation when the browser supports it - reduce code duplication - drop plain HTML chat - reduce hardcoded styling - minor cleanups
Revert massive replacement of empty list creation sentences. The use of '[list]' instead of '{}' adds semantics that could be used for performance improvements in the future, such as using a different internal representation. There is already work in this direction, avoiding the generation of the string representation during comparison of empty strings (huge thanks to Stefan Sobernig for the pointer: https://core.tcl.tk/tcl/info/44527c632ed609c2).
