This removes the Trait, yes… 

Removing in the sense of Flattening (that is, remove the Trait but change the 
class to contain the methods, e.g. to port to a system without Traits) is 
interesting.. it would be more
like a refactoring…

I thought the question was how to install/duplicate the trait methods on each 
client (maybe for a deployment image without Traits). I had the same question. 
Doesn’t the suggestion remove the trait completely or am I missing something?

Hi Marcus,

Thanks for your reply - very much appreciated.

This is the approach I’ve taken and so far so good :)

Cheers,

You can just create

you could use the class installer / class builder, e.g. imagine you have:


Object subclass: #MyVisitor
uses: TRBProgramNodeVisitor
instanceVariableNames: ''
classVariableNames: ''
package: ‘PackageTest’


you can now remove the Trait with:


ShiftClassInstaller make: [ :aClassBuilder | 
aClassBuilder fillFor: MyVisitor.
aClassBuilder traitComposition: {  }  
 ]
