Hi all,
I have a question about metacello configuration. Given the following default method:

ConfigurationOfFAMIXSQL>>default: spec
�� <version: 'default'>
��
�� spec for: #common do: [
�� spec blessing: #default.
�� spec repository: 'http://www.squeaksource.com/Moose'.
��
�� spec� project: 'PetitSQLParser for MooseJEE' with: [
�� spec
�� className: 'ConfigurationOfPetitSQLParser';
�� file: 'ConfigurationOfPetitSQLParser';
�� version: 'default';
�� repository: 'http://www.squeaksource.com/PetitSQLParser' ].
��
�� spec
�� "Core"��
�� package: 'Famix-SQL';
��
�� "importers"
�� package: 'Moose-SQL-Importer' with: [spec requires: #('PetitSQLParser for MooseJEE' 'Famix-SQL').];
��
�� "Tests"
�� package: 'Famix-Tests-SQL'with: [spec requires: 'Famix-SQL'];
�� package: 'Moose-Tests-SQL-Importer' with: [spec requires: 'Moose-SQL-Importer'].
��
��
�� spec group: 'Model' with: #('Famix-SQL').
�� spec group: 'Model-Tests' with: #('Famix-Tests-SQL').
��
�� spec group: 'Importer' with: #('Moose-SQL-Importer').
�� spec group: 'Importer-Tests' with: #('Moose-Tests-SQL-Importer').
��
�� spec group: 'default' with: #('Model' 'Importer').
�� ]

When I ask to load default.� What metacello look at: the pragma, the blessing: or the group:?

depend what are you talking about. Version or packages/groups?

ConfigurationOfFAMIXSQL project xxxVersion load -> that loads the default packages/groups, in you case, � spec group: 'default' with: #('Model' 'Importer').
In that case you load a version XXX and from that version you load the default packages/groups

(ConfigurationOfFAMIXSQL project version: 'default')� load ->� the same as the previous one, but instead of version XXX you load version 'default'.
Notice that Metacello knows NOTHING about calling versions as "default". That's something I saw in moose guys.
�

It would be possible to load just the Model group? and How can I do that?

ConfigurationOfFAMIXSQL project xxxVersion load: 'Model'.
(ConfigurationOfFAMIXSQL project version: 'default')� load: 'Model'.

I recommend you to read the Metacello chapter: https://gforge.inria.fr/frs/download.php/28462/Metacello.pdf

Cheers

Thanks a lot,
