#15784: :doc shouldn't report <has no documentation> for a data constructor when it can show docs for the type constructor of the same name and type -------------------------------------+------------------------------------- Reporter: sjakobi | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 8.6.1 Keywords: newcomer | Operating System: Unknown/Multiple Architecture: | Type of failure: Poor/confusing Unknown/Multiple | error message Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- {{{ λ import Data.Monoid λ :doc Sum <has no documentation> Monoid under addition.

getSum (Sum 1 <> Sum 2 <> mempty) 3 }}}

I think it would be nicer if we could elide the `<has no documentation>` message for the `Sum` data constructor here. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15784 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
