#12390: List rules for `Coercible` instances -------------------------------------+------------------------------------- Reporter: Iceland_jack | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: newcomer 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 tellah): Newcomer here who has been poking around this a bit. From my initial impressions of the `:info` code, it would appear that the only place such an info string could be stored is in the TyThing. This is because the input string is converted String -> Name -> TyThing, and then the TyThing is converted to an IfaceDecl for printing. So then the question is: where does the suggested info string come from? I have some basic code that can store arbitrary text for `:info` but I am not sure what the front end for this should look like. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12390#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
