Kilon,

Do you have a preview version of the updated book?

I would love to see it.

Also would you consider adding some exercises will be a good addition? I think so....let me know and i guess i can merge the project i've started to the updated book.

Best

Asunto: Re: [Pharo-users] Unintuitive behavior of class-side initialize

I will be adding an "Introduction to Object Orientation" chapter to the new updated Pharo By Example online book, so I will add this to the chapter. The chapter will target people not familiar with Object Orientation and people new to coding. Its not an immediate target but it will happen till the end of the year.

As class is just an object in Smalltalk, it would be reasonable to believe
that #initialize message is always sent to class on creation.

However, that's not true. It is only sent to classes that redefine
#initialize. Also sending super initialize may lead to problems.

Ohhh yes. There is always a time for every Smalltalkers where you discover that doing super for class side initialize is not a good idea.

Here was my time: http://forum.world.st/super-initialize-is-not-a-good-idea-for-Behaviors-td3086162.html

 

None of these is mentioned in documentation (I assume Pahro By Example is
the official one). It only says that #initialize is sent when class is
loaded into memory.

I think either this behavior should be made more consistent, or excplicitly
mentioned in the docs.

+1 to the documentation
