Dale, Indeed, tags such as pharo1.0, pharo1.1, pharo1.2, etc. will likely be needed for some packages when we have universes for different Pharo versions. Cheers, Adrian On Mar 20, 2010, at 20:45 , Dale Henrichs wrote:
George,
At the moment there is no overall way to do that for Pharo. For GemStone I have attributes for specific versions, so for GemStone I can write a spec like this:
spec for: #common do: [...]. spec for: #gemstone do: [...]. spec for: #'gs2.4.x' do: [...]. spec for: #'gs3.x' do: [...].
So I can specific packages that are only loaded in GemStone 2.4 or GemStone 3.0.
For Pharo I would imagine doing something like the following:
spec for: #common do: [...]. spec for: #squeakCommon do: [...]. spec for: #pharo do: [...]. spec for: #'pharo1.0' do: [...]. spec for: #'pharo1.1' do: [...].
Then packages that were specific to 1.0 and 1.1 can be specified. I haven't added this to Metacello for Pharo, because I was kind of waiting for the need to appear rather than add a feature that noone needs, so I've been waiting for someone to ask for the feature:)
