Auto create new and initialize methods for new class?

Hi, is there an automated setting which creates default new and initialize methods for a new class? BTW, I'm using Pharo 2.0-one-click. Well, I must go and thanks in advance.

Think different and code well,

Dirty way:

You can modify Class>>subclass:instanceVariableNames:classVariableNames:poolDictionaries:category: like this:

subclass: t instanceVariableNames: f classVariableNames: d poolDictionaries: s category: cat

"This is the standard initialization message for creating a new class as a

subclass of an existing class (the receiver)."

| newClass |

newClass := (ClassBuilder new)

superclass: self

subclass: t

instanceVariableNames: f

classVariableNames: d

poolDictionaries: s

category: cat.

newClass compile: 'initialize'.

^newClass.

Yes, very dirty.

why do you need to implement #new so often? It's kind of rare in the
code I've read.

For initialize, if you use Nautilus:

- select your class
- CMD+SHIFT+I

enjoy :)

Ben, you should move to somewhere OUTSIDE the menu "analyze" or rename analyze ;)

why do you need to implement #new so often? It's kind of rare in the
code I've read.

Hi, I would like to initialize the objects I create with some reasonable defaults and I don't want to have setters and getters for every instance variable.

So, how do you create a new instance of a class?

#new calls #initialize by default.

So the only thing you need to implement is the #initialize method on your class.

Of course he will, he is the author ;)
BTW, I also do recommend it.

If so, what's the installation steps?

You should do that :)

But in Pharo 2.0, it's the default browser.

OK, I'm using Pharo-2.0-one-click so I'm good to go in regards to Nautilis.

don't touch #new. Just implement #initialize and set your fields there.

To everyone on the mailing list: we should encourage people to ask
such kind of questions on stackoverflow.com.

why do you need an automatic new method?
Because by default
new invoke initialize

and it works well.

Damien, this is a great point and I'll ask such questions there in the future.

Stéphane, I have been using VW Smalltalk and it creates new classes ,by default, with a #new method on the class side and a #initialize method on the instance side.

In Pharo, new is built-in and calls initialize. I have a cool little hack that gives you the option to automatically create/add to #initialize as instVars are added. I'll post it in case that helps you...

Yes, true in VW, but unecessary in squeak/pharo, this is in
Behavior>>new
^ self basicNew initialize

Also, a generally good rule is to remember to send super initialize
(very few exceptions).
