How to query all Monticello packages from a Metacello Configuration?

Question

I have a Metacello configuration like ConfigurationOfAthens and I want to know which packages provides, the result would be :

• Athens-Cairo
• Athens-CairoPools
• Athens-Core
• etc.

I tried

(GoferConfigurationReference name: 'ConfigurationOfAthens') packages.

but it is not understood by the system.

It this supported in Pharo 4?

If you want just the package names you could use helper classes to query from a Configuration. And so your query would be

(MTProject 
    newFromVersion: (ConfigurationOfAthens project version: #development)
    inConfiguration: ConfigurationOfAthens) dependenciesFilteredBy: MTPackage.

These MT classes - which sounds like they should belong to Metacello - are not in Metacello package, but currently in Versionner (included by default in Pharo images).

Diving into results reveals that some "MTPackages" has not their corresponding "RPackage" (this could be a bug, or some weird feature in the package representation models). So you would need further filtering:

((MTProject 
    newFromVersion: (ConfigurationOfAthens project version: #development)
    inConfiguration: ConfigurationOfAthens) dependenciesFilteredBy: MTPackage)
        select: [ :pkgName | 
            (RPackageOrganizer default 
                packageNamed: pkgName name asSymbol
                ifAbsent: []) notNil  ]
