load involves loading a project into an image in which the project
does not exist.
upgrade involves loading a project into an image in which the
project already is loaded.
Loading is straightforward ... it is what we do all of the time. Add
a bunch of classes and methods, then run the #initialize methods for
the new classes.
Upgrading is interesting because besides adding/removing classes and
methods, you have to worry about completely unloading packages that
are no longer part of the project. You also have to worry about the
fact that new classes will get there #initialize methods, but
preexisitng classes will not ... which can lead to interesting
results. This may lead to pre/post upgrade doits...
I easily understand the difference. I was just wondering whether load:
cannot do an update: if the package is present already. Maybe as I
user I should not take care whether a package is already present
before loading it. Just a thought.
Remove is interesting because you have to also consider removing any
projects that are dependent upon the project being removed.
Once Metacello 1.0 is released I start working on adding upgrade
and remove to Metacello.
Sounds like a good plan!
Thanks for your explanation.
