Hi !
I would like to work with Traits in Squeak 3.9g, too. The current VM and Image run very stabble.
The Traits researcher form Bern provide an image 3.9a where Traits are included. But this image is terribly unstable and I am accustomed now to 3.9g. I want to port the Traits functionality to Squeal 3.9g. How can I do that ?
The thing is, I read that Traits are included in Squeak 3.9g. I can find the Trait classes and categories. But I cannot create Traits...the Browser doesn't recognize the term Trait oder named or fromClass e.g. Trait named: #TsomeTrait fromClass: someClass uses: {something} category: 'some_category'
SqueakMap always complains when I want to install Traits. I read sth. about loading .mcz files, but the FileList Browser doesn't let me to load.
What can I do to make it work ?

How can I create a trait from a class in Squeak 3.9 final ? In previous version I could use e.g. "fromClass: Class1". (http://www.iam.unibe.ch/~schaerli/smalltalk/traits/traitsPrototype.htm) In 3.9 final this message is not recognized anymore.
Best regards, Warakorn

How can I create a trait from a class in Squeak 3.9 final ?
What do you mean?
If this is taking a class and turning it into a trait. Basically you cannot. It was never the case or I do not understand what you mean.
In previous version I could use e.g. "fromClass: Class1". (http://www.iam.unibe.ch/~schaerli/smalltalk/traits/ traitsPrototype.htm) In 3.9 final this message is not recognized anymore.

In the example of this site, there is a point 3) Generating a trait from a class. http://www.iam.unibe.ch/~schaerli/smalltalk/traits/ traitsPrototype.htm
TTrait named: #TPoint fromClass: Point includeSuperUnit: nil uses: {} category: 'Traits-Temp'
The authors say "When generating a trait from an existing class, the system automatically replaces instance variable accesses through accessor methods." Moreover they say the class serves as a source.
Exactly the same thing I would like to do in Squeak 3.9final, too. But I don't know how to do it. If the people, who are doing the research on Traits, included this functionality in March 2003, why isn't there in 2006 ?

I'm one of the authors and this features was experimental and since adrian rewrote entirely traits to have them much better implemented we did not provide that functionality but it should be easy to reimplement with a bit of metaprog magic. But we will not do it because too busy.

Because in march 2003 we were brainstorming and nathanael hacked and pacthed squeak to make traits worked. and in 2006 everything was reimplemented and this is much better. :)
