Tips on how to distribute platform-specific fragments? [message #502339]

Hello,

Sorry if this is a little bit of a simple question, but I'm afraid that I don't
really know the best way to do this.

I have a feature that has several plug-ins. There is one plug-in that relies on
platform specific code. So, it is a perfect candidate for using fragments to
distribute the code. I'm not really sure what the dependency/platform filter set
up should be for distributing with P2 should be, though.

For example, if I have my feature set up, should it have a set up like:

My Feature
-My Plug-in 1
-My Plug-in 2
-My Windows Fragment
-My Linux Fragment
-My Mac Fragment

What confuses me about this set-up is that it is obvious that all three
fragments should not be installed on every system. Will P2 work properly if I
include all 3 in the feature, but then set up the "Environment combinations" to
filter out invalid OS's? The Plug-ins and Fragments page of the feature editor
is a little confusing to me on this point. Thanks.

Del

One of the simplest patterns is to include all fragments in your feature and then set their platform/arch/windowing system properties. See the platform feature [1] how it deals with org.eclipse.core.filesystem and those fragments.
