Cross-platform configurations?

Hi,

I'm rooting around trying to find some pointers on how best to write
cross-platform configurations. At the moment I have
http://www.squeaksource.com/Control/ConfigurationOfControl-fbs.11.mcz
which attempts to have a normal install for Squeak, and add a shim to
Pharo (1.4) in the form of a ControlPharo package.

My problem is that ControlPharo isn't being loaded into a Pharo image.
My baseline looks like this:

baseline10: spec
        <version: '1.0-baseline'>

        spec for: #'common' do: [
                spec blessing: #'baseline'.
                spec repository: 'http://www.squeaksource.com/Control'.
                spec
                        package: 'Control';
                        package: 'ControlTests' with: [
                                spec requires: #('Control' )].
                spec
                        group: 'default' with: #('Core' 'Tests');
                        group: 'Core' with: #('Control');
                        group: 'Tests' with: #('ControlTests') ].
        spec for: #'squeak' do: [ ].
        spec for: #'pharo' do: [
                spec
                        package: 'ControlPharo'].

and the version looks like this:

version11dev: spec
        <version: '1.1.dev' imports: #('1.0-baseline' )>

        spec for: #'common' do: [
                spec blessing: #'development'.
                spec description: 'stable version'.
                spec author: 'fbs'.
                spec timestamp: '07/14/2012 21:37'.
                spec
                        package: 'Control' with: 'Control-fbs.19';
                        package: 'ControlTests' with: 'ControlTests-fbs.15'. ].
                spec for: #squeak do: [ ].
                spec for: #pharo do: [
                        spec
                                package: 'ControlPharo' with: 'ControlPharo-fbs.1' ].

(Now note the #pharo vs #'pharo' - I know that's wrong, and just
happens to work, but using #'pharo' doesn't fix the configuration.)

What have I missed?

Note the 'Core' group being defined differently for #'common' and #'pharo'.

Frank,

The pattern for including a platform-specific package is the following:

    spec
        for: #'pharo'
        do: [
            spec
                package: 'Control' with: [ spec includes: 'ControlPharo' ];
                package: 'ControlPharo' with: [ spec requires: 'Control' ] ]

The `includes:` message says that 'ControlPharo' should be "included in the load" whenever 'Control' is referenced.

Then you specify that 'ControlPharo' is loaded after `Control`....

This is much better than using a group (I think) because `ControlPharo` is tightly coupled to 'Control'...

Ah, thanks Dale! (ControlPharo is actually completely independent of
Control: it's a single method that Squeak has and Pharo doesn't.
Control is thus heavily dependent on ControlPharo though.)
