Re: lookupRdrNameInModuleForPlugins with constructors

Got it. Silly me. Thanks!! - Conal On Tue, Mar 22, 2016 at 5:25 PM, Andrew Farmer wrote:

Er, dictionary... sorry, mkDataOccFS

mkVarUnqual calls mkVarOccFS, which constructs an OccName in the varName namespace. You need to construct your RdrName via mkTyVarOcc, which picks the Type/Class namespace.

I'm trying to construct a dictionary in a GHC plugin. I'm stuck on finding the constructor for the dictionary. When I use `-ddump-simpl` on the module that defines the class, I see "Circat.Rep.C:HasRep". To try finding that constructor, I say

...

lookupRdrNameInModuleForPlugins hsc_env (mkModuleName "Circat.Rep") (mkVarUnqual "C:HasRep")

However, I keep getting `Nothing` as a result. (Same without the "C:".) I've also had this same difficulty when looking up constructors for algebraic data types and when looking up TyCons. For regular value Ids, lookup succeeds.

What am I missing?

Thanks, - Conal
