Hi Dale. For Pharo 1.3 I want to (try) to use all #stable, i.e, I want
that ConfigurationOfPharo doesn't explicitly load a specific version of
every project but instead, the #stable.
First step I need to do (I will try to do it during the weekend) is to
update #stable in each of the ConfigurationOf used by
ConfuigurationOfPharo. That's an easy part.
Now, my question is...I don't really understand how the confs would look
like after. I mean, 99% of the cases (in fact, at the beginning it will
be 100% until I find a problem), the version I use will be #stable.
So,the version of ConfgiruationOfPharo AND all the Configurations used
by ConfgiruationOfPharo would look something like this:
spec
project: 'Autotest' with: #stable;
project: 'Autotest Help Tests' with: #stable;
project: 'MemoryMonitor' with: #stable;
project: 'XMLSupport' with: #stable;
I mean...every single project reference will have #stable instead of a
specific version. So...is this expected? is this the way I should do it ?
Finally...is there a query I can do to Metacello saying "which are the
ConfigurationsOf needed for this version for this group of this Conf" ?
Thanks

Mariano,
My rule of thumb for a literal version spec is that you should use the
#stable symbolic version if the project is loosely coupled to your
project and a specific version otherwise. OmniBrowser tends to be
loosely coupled as you are interested in getting any old version of
OmniBrowser as long as it functions on the platform.
The rule of thumb for a baseline version spec is to use #stable for all
projects (as long as the #stable version is defined), even "tightly
coupled" projects. When the baseline version is loaded, you normally
don't want to load the "latest code" or all of the projects that you
depend upon.
The #bleedingEdge symbolic version should be used only when the
referenced project is part of your project family.
When I load the baseline version for Seaside30, I want to load the
#bleedingEdge versions of Grease, Kom, and Swazoo, because they are part
of the project family. I absolutely don't want to load the latest
OmniBrowser code, because who knows what you'd get...
So for the ConfigurationOfPharo, if you followed my rule of thumb, you
would create a baseline version and use the #stable version for all of
the projects in the baseline. In the literal version you would use the
explicit version, so that you'd have an explicit repeatable
specification for a set of projects that were known to work together.
Developers interested in getting the "latest released version for all
projects" in ConfigurationOfPharo would load the baseline version and
then get the #stable version of all the projects for their platform ...
each of the projects was know to work by itself in an image (that's what
the #stable designation means), but the unknown is whether all of the
projects work together in image ... When you know that, you create a
literal version of ConfigurationOfPharo to commemorate that set of
versions....
Without looking at the list of projects, it might still make sense to
use #stable in the literal version, but it would be the exception to the
rule ...
Does this make sense to you?
Dale
