ConfigurationOf and BaselineOf subclassing

Hi,

        It is need - obligatory

                ConfigurationOf.................  is subclass of ConfigurationOf  class

        and
               
                BaselineOf.................. is subclass of BaselineOf   class

       
        I see Object subclass: #ConfigurationOfPier3


        I have  ( but i don't remember because ):

        Object subclass: #ConfigurationOfDtrBase
        instanceVariableNames: 'project'
        classVariableNames: 'LastVersionLoad'
        category: 'ConfigurationOfDtrBase'

        it's correct?

        This class implementing:

        project

        ^ project ifNil: [ | constructor |
                "Bootstrap Metacello if it is not already loaded"
                self class ensureMetacello.
                "Construct Metacello project"
                constructor := (Smalltalk at: #MetacelloVersionConstructor) on: self.
                project := constructor project.
                project loadType: #linear.
                project ]

        I't's best change to:
       
                ConfigurationOf subclass: #ConfigurationOfDtrBase
                instanceVariableNames: ''
                classVariableNames: ''
                category: 'ConfigurationOfDtrBase'

        and remove the project method?
       
        Thanks,

                Dario

Dario,

If your configuration will only be used in images where the Metacello
Scripting API has already been installed, then I think it is a good idea
to start using the subclass of ConfigurationOf. As you've observerved,
by subclassing you don't need to copy the new class from from a template
to make sure that all of the necessary methods are supplied ...

In your scenario, where this a project based in a git repository, I
really recommend that you use a BaselineOf and stop using
ConfigurationOf altogether ... with a BaselineOf you don't need to
continually update the version method with new package versions ...
