Hi,

You can find useful information into the 'Deep into Pharo' book, chapter 9 (Managing projects with Metacello), section 9.12 (platform specific package).

Example:
ConfigurationOfCoolBrowser>>baseline09: spec
<version: '0.9-baseline'>
spec for: #common do: [
spec blessing: #baseline.
spec repository: 'http://www.example.com/CoolBrowser'.
spec
package: 'CoolBrowser-Core';
package: 'CoolBrowser-Tests' with: [ spec requires: 'CoolBrowser-Core' ];
package: 'CoolBrowser-Addons' with: [ spec requires: 'CoolBrowser-Core' ];
package: 'CoolBrowser-AddonsTests' with: [
spec requires: #('CoolBrowser-Addons' 'CoolBrowser-Tests' ) ].
spec
group: 'default' with: #('CoolBrowser-Core' 'CoolBrowser-Addons' );
group: 'Core' with: #('CoolBrowser-Core' 'CoolBrowser-Platform' );
group: 'Extras' with: #('CoolBrowser-Addon');
group: 'Tests' with: #('CoolBrowser-Tests' 'CoolBrowser-AddonsTests' );
group: 'CompleteWithoutTests' with: #('Core', 'Extras' );
group: 'CompleteWithTests' with: #('CompleteWithoutTests', 'Tests' )].
spec for: #gemstone do: [
spec package: 'CoolBrowser-Platform' with: 'CoolBrowser-PlatformGemstone'].
spec for: #pharo do: [
spec package: 'CoolBrowser-Platform' with: 'CoolBrowser-PlatformPharo'].

Hi,

I have my project with my Configuration and I am using spec groups to load different sets of packages (e.g., development and user groups).

With the porting to Pharo 4.0 I discovered that there are some functionalities specific to Pharo 3.0 and others to Pharo 4.0, for example the fact that MethodContext is no longer part of Pharo 4.0. but it has been replaced by Context.

I moved such functionalities in a package, say 'MyProject-Extension30� and Pharo 4.0 specific functionalities in 'MyProject-Extension40�.

Now the question is, suppose that I have a group like
spec group: �User' with: #(�A� �B� �C�).

and another one:
spec group: �Dev' with: #(�A� �B� �C� �D� �E�).

Until now, the developer (i.e., me) would do something like
(self project version: #bleedingEdge) load: #('Dev�)

and a used of my project would do
(self project version: #bleedingEdge) load: #(�User�)



How can I factor inside the dynamic load of the two Pharo-version specific packages?
i.e., no matter if �User� or �Dev� group is loaded I need to load 'MyProject-Extension40� if I am on Pharo 4.0 and 'MyProject-Extension30� if on Pharo 3.0.

Thanks for your help,
Roberto
