The TyCon has a Name (use tyConName to get it). The Name has a Module and an OccName (use nameModule and nameOccName to get them) The OccName has a string (occNameString) The Module has a ModuleName and a Package.
All of these will give the “original-name” info, ignoring what’s in scope. Does that help? S From: Glasgow-haskell-users [mailto:glasgow-haskell-users-boun...@haskell.org] On Behalf Of Ranjit Jhala Sent: 25 January 2017 00:09 To: glasgow-haskell-users@haskell.org Subject: Accessing the "original" names via GHC API Hi, I'm quite vexed trying to do the following. Suppose I have a file: ``` module Foo import qualified Data.Set as S baz :: S.Set Int baz = S.empty ``` My goal is to write a function tyconString :: TyCon -> String (perhaps with extra parameters) such that given the `TyCon` corresponding to `Set`, I get back the "original" name `S.Set`, or even `Data.Set.Set`. Everything I've tried, which is fiddling with different variants of `PprStyle`, end up giving me `Data.Set.Base.Set` Does anyone have a suggestion for how to proceed? Thanks! - Ranjit.
