#15167: DerivClause list is not populated for (TyConI (DataD ...)) -------------------------------------+------------------------------------- Reporter: 0xd34df00d | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Template Haskell | Version: 8.4.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): Unfortunately I don't think we currently have a good way to get this information. When we are asked to reify the tycon the original Haskell AST (which would contain the `deriving` information) that we typechecked to produce the type is gone. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15167#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
