Hi Peter,

Iâve never had to use the provides: method even with fairly complex Baselines.

This is an example of the kind of thing Iâve been using:

baseline: spec
	<baseline>

	spec for #common do: [
		spec 
			âDependency on project with BaselineOf"
			 baseline: 'Seaside3' with: [ 
				 spec 
					 loads: #('Core' 'Development' 'Zinc'); 
					 repository: 'github://SeasideSt/Seaside:master/repository <github://SeasideSt/Seaside:master/repository>' ];

			âDependency on project with ConfigurationOf (note the version)â
			configuration: âMagritte3â with: [ 
				spec
    					versionString: '3.5.2';
                			repository: 'http://www.smalltalkhub.com/mc/Magritte/Magritte3/main <http://www.smalltalkhub.com/mc/Magritte/Magritte3/main>' ];

		âNow define my project packagesâ
		package: 'MyProject-Model' with: [ 
			spec requires: #(âMagritte3') ]; 
		package: âMyProject-UI' with: [ 
			spec requires: #('MyProject-Modelâ 'Seaside') ];
		package: âMyProject-Tests-Modelâ with: [
			spec requires: #('MyProject-Modelâ) ];

		âNow define groups for convenience. Groups can load dependencies, packages, or other groupsâ
		group: âModel' with: #(âMyProject-Modelâ);
		group: âUI' with: #(âMyProject-UIâ);
		group: âTestsâ with: #(âMyProject-Testsâ)

		âMetacello will load the default group unless you specify otherwise"
		group: âdefaultâ with:  #(Modelâ âUIâ);

		âOther possible convenience groupsâ
		group: âDevelopmentâ with:  #(Modelâ âUIâ âTestsâ);
		group: âProductionâ with:  #(Modelâ âUIâ)
	]

Then you can load groups like:

Metacello new
	baseline: âMyProjectâ;
	repository: âgithub://MyGitHubUser/MyProject:master/repository' <github://MyGitHubUser/MyProject:master/repository'>
	loads: #(âDevelopmentâ);
	load

Hope this helps :)

Cheers,

Jupiter

Hi,
I'm trying to define a dependency on a group of BaselineOf.
specifically #core of github://pharo-graphics/Bloc/src.
I've looked at this https://github.com/Metacello/metacello/blob/master/docs/GettingStartedWithGi... <https://github.com/Metacello/metacello/blob/master/docs/GettingStartedWithGi...>
which recommends using import:provides:
baseline: spec
  <baseline>
spec for: #common do: [
    "Sample defines the group 'default'"
    spec baseline: 'Sample' with: [
      spec repository: 'github://dalehenrich/Sample:master' ].
    spec import: 'Sample' provides: #('default').
"OtherSample *also* defines the group 'default'"
    spec baseline: 'OtherSample' with: [
      spec repository: 'github://dalehenrich/Sample:master' ].
    spec import: 'OtherSample' provides: #('default').
"'default' can now be successfully resolved, even though
    both projects define the same name"
    spec package: 'OtherProject-Core with: [
      spec requires: 'default' ] ].
However this code is confusing... both Sample & OtherSample provide `default`, so on what does `OtherProject-Core` actually depend?
In the examples here https://github.com/Metacello/metacello/blob/master/docs/LockCommandReference... <https://github.com/Metacello/metacello/blob/master/docs/LockCommandReference...> there are groups with the name of the project in them ('External Core' 'External Tests'), but this won't work if I don't control the project I am loading, plus it feels like a hackish workaround.
Also, can it be unified with the way ConfigurationOf works?
Thanks,
Peter
