Hi Everybody,
I try to be up-to-date with Pharo trends and releases. In Pharo 12, we
are switching to use fluid class declaration. Its' not easy to find
stuffs illustrating fluid API. I have spend many hours to browse Pharo
documentation, Github repos, slides, MOOcs, books, papers finding a way
to clearly explain this "new way" of declaring a class. All Pharo
introduction resources and Pharo 12 videos do not use fluid class
declaration but the "old" way. I also use (and let's say teach) Pharo in
my OOP lectures 😉
If I'm not wrong, the fluid class declaration does no more explicitly
deal with instance (and class) variables. Instead, it deals now with
slots, tags, shared variables, traits,...At a fist look, I was
understanding that slots was a dynamic way to declare instance
variables. After reading some pieces of paper, and if I'm not wrong ,
slots are not really instance variables and shared variables are not
class variables.
Avoiding the old class declaration, i.e.
     Object subclass #SomeClassName instanceVariableNames: 'instaVar1
instVar2 ...' ...
is there a simple way to add an instance (or class) variable? Are
instance variables gone in Pharo? I assume I missed something, but what?
Many thanks. Cheers,
Herve
