sounds like they are talking about a glade like thing with a json/edc style syntax... and a few other doobies. some thing we have learned: 1. programmers hate designing gui's... in text - because they have to guess/imagine the results. it doesn't work. we need to design a gui in a gui. it may, in its internals have text or somethig else - but that is not relevant... as long as its EASY to bind to code that talks to the gui. 2. edc was way too verbose and was nothing more than really an exposure of edje structures. if you write such things you design it for writing in text - not as a simple exposing of internals 3. what we ended up with is that a declarative ui is mostly just the display of properties, and the declaration is simply a way of expressng that. edc/edje were too basic and elm is too much of a traditional set of widgets. we need to marry both - and that is what the adam/eve thing is seemingly doing at the glade/widget level. 4. we need a faster way to implement logic of ui elements and trivially inherit them and PATCH them. not just inherit then override - too coarse. what people need 90% of the time is an xisting ui element/widget with a few lines of extra logic here and there. i don't want to focus on any kind of json/c-like or xml file at all - it's wrong. been there. done that. not useful. you need a gui to design a gui. :) well ok - some of us can live without but MOST can't. :) lua (luajit) should solve the "quickly build ui element logic" problem and still keep thing pretty fast and lean. bob is waiting for eo2/eolian so we can expose efl bindings without manually doing them all ourselves. beyond that is pretty much building the layout elements we want in lua and a gui editor for it. > Hello all, > > I would like to share some ideas for Bob, which I see as an evolution > of edje.
