Hi Dale,
then a question: how does one query a baselineOf or a configOf
to retrieve the current project state (i.e. packages) loaded
in the image?

Thierry,
Good question:)
To start with in tODE I have a class
TDMetacelloProjectRegistrationDefinition which is part of the
following hierarchy:
Object
TDDefinition
TDPackageBasedDefinition
TDAbstractProjectRegistrationDefinition
TDGitProjectRegistrationDefinition
TDMetacelloProjectRegistrationDefinition
TDMetacelloRegistrationDefinition
TDMetacelloBaselineRegistrationDefinition
TDMetacelloConfigurationRegistrationDefinition
TDMetacelloHybridRegistrationDefinition
TDMetacelloUnloadedProjectRegistrationDefinition
The method
TDMetacelloProjectRegistrationDefinition>>workingCopies[1]
calculates the list of MCWorkingCopy instances for the loaded
packages associated with a project (including the configurationof
or baselineof... or both).
The key Metacello methods called include:
MetacelloProjectRegistration>>projectVersion[2]
MetacelloMCVersion>>packages[3]
MetacelloPackageSpec>>workingCopy[4]
MetacelloMCProjectSpec>>projectPackage[5]
This is really the key information for doing all of the other
operations for a "Project Browser" like "save all dirty packages
and commit" and "give me diffs for all dirty packages in project"...
I was just asking that because I'd like to see that information merged
as much as possible; separating concepts just strikes me as unneeded
complexity, at least for baselines.
Not sure what you mean by "separating concepts and unneeded complexity".
I provided a picture of some of the abstractions that I am using in tODE
... these abstractions are used in a number of commands, but I also
tried to provide you with the basic implementation used in tODE in case
you were interested in the fact that tODE includes the BaselineOf
package in the list of packages for a project...
The simple answer is MetacelloMCVersion>>packages[3]
Configurations are a bit different, since a configuration can snapshot
multiple versions. But I'd really like to make it simple and obvious
how to setup a project.
I'm not sure what you are talking about here.
In Metacello a BaselineOf has a single version and the
MetacelloMCVersion class manages the version ... Yes, a Configuration
has multiple versions and each of those versions is an instance of
MetacelloMCVersion....
Perhaps when you have time, you can provide a bit more information about
what you are trying to do ...
I apologize if I provided too much information but when working with
folks in different time zones, I am in the habit of packing as much
information in a message as possible, because it's often a 24 hour
turnaround for responses... (as it is in this case:)
