Hello
All this is explained in the Mooc (with mutliple videos and gradually)
and Pharo by Example chapter.
Pay attention you do not need to understand the metaclass core to program in
Pharo.
This is just for fun and a bonus. This is why in general I do not show this
diagram directly.
Check
#subclassResponsibility is defined in Object.
A good way to find this out is to
- select 'subclassResponsibility' with the mouse
- type Control-M
Control-M asks for a list of the iMplementors of the method.
Control-N asks for a list of the seNders of the message.
This particular method just rais
I'll add a small bit to Davide's excellent answer, by way of connecting
some of the dots. In particular, the browser makes a class look like one
thing and we talk about instance side and class side.
The reality is that the browser presents either the class' behaviours or
the metaclass' behaviours,
Objects are instances of a class.
Classes are objects, so they have methods.
'self class' returns the class of self.
If a class doesn't have a methods ...
... the search continues in the superclass.
(every class has a superclass ... apart from Object).
If you download the Blue Book - "Smalltalk
I understand if you have Class A with methods p and q that you can call q from
p doing:
self q
But there are some cases where a method doesn’t exist but self is still used.
I found a tutorial on creating a Reddit type app and it had a .mcz which I
loaded.
Here is an example from Class StLogg

Lua is an inspiration from that perspective.
Now we play the game because publishing is also a nice way to understand what
we are doing
and because this is important to play the game else we would be considered as
losers.

Hi,
Just to add a little bit to Tim's remark, I'm pretty happy that Pharo

Dear happy Pharoers and others,
Over the last months we have been working on the implementation of a
MIT-licensed ARMv8 Just-In-Time compiler for Pharo VM.
We are very happy with the advance on this subject, as we have not only
implemented a new backend but we have added more than 2500
tests t
It is a bug when you have a lot of budget. Luckily we have the monthly
sprints :).
Participants are always more than welcome. You can join and participate to
fix these things the last friday of each month!
I can sit with you and pair program.
I am not sure if this month we have sprint, since it is
Just to chip in here - the work demonstrated on Pharo development is
inspirational. Rather than throwing everything away, it shows the alternative -
incrementally improving a running platform - and practicing what we preach in
industry by refactoring a large elderly code base bit by bit - it's r
