Hi,
I summarize below why I think fine grained configurations should be
preferred to groups.
The group is not a first class configuration, although it can be
depended on. If you depend on a group of a configuration, it's harder
to understand the consequences and it's harder to build tools for it.
Consider the graph below representing the dependencies starting from
ConfigurationOfMoose #development:
Inline image 2
It's a simple representation of dependencies, and it makes the maze of
configurations easier to grasp. The interesting thing about it is that
by showing a configuration node only once, you can see how multiple
other projects depend on it. For example, HashTable is being depended
on by two distinct configurations.
You can also see that Magritte depends on Grease, but you do not see
that it only depends on the Core group. To do that, you have to look
at the details of the edge.
We used to have groups in GT, however, after a while we moved to more
fine grained configurations. As a consequence, you can see that
GlamourCore (which used to be a group in Glamour) is being depended on
by three different configurations. Using first class configurations
makes tool building (like representation, navigation or release) easier.
You could argue that we could represent a Group as node, however, even
then you would not be able to see dependencies between groups that
reside within the same configuration because groups are not first
class configurations that can explicitly define dependencies, they are
just groups.
Groups might provide an apparent ease of use for quick things, but I
strongly believe that they are an unessential construct and that if we
would not use them, tools would become cheaper and more effective.
Cheers,
Doru

Ok for me, do as you prefer. What is your rationale?
