I'd love to know a nicer way to do this, but what Ben Lippmeier did as a workaround is require a binding

"repa_primitives = R.primitives"

where repa_primitives is a record with references to all the primitive types you need. It's not great, but it works.

Plugin code:

http://code.ouroborus.net/repa/repa-head/repa-plugin/Data/Array/Repa/Plugin/Primitives.hs

Primitives export:

http://code.ouroborus.net/repa/repa-head/repa-series/Data/Array/Repa/Series/Prim.hs

In writing GHC plugins, how can I (a) add a module import (preferably qualified) and (b) make vars/ids for names imported from the newly imported module (to insert in the transformed Core code)?

If it's not possible to do what I want, I'd be willing to require an explicit import (say "import qualified Foo") in client code, as a temporary workaround.
So far I've been unable to import even from the base package. Maybe I'm missing something basic that you folks have learned.

My simple & unsuccessful attempt is at https://github.com/conal/plugin-import-id . Help greatly appreciated.

Thanks,
