[GHC] #9437: Wrong error message when using `..' with a record update

#9437: Wrong error message when using `..' with a record update -------------------------------------+------------------------------------- Reporter: elliottt | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Keywords: | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Unknown | Type of failure: Blocked By: | None/Unknown Related Tickets: | Test Case: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Using `..' inside of a record update should report that it's an error to do so, but instead reports that it's an empty update. Consider this module: {{{ {-# LANGUAGE RecordWildCards #-} module Test where data Foo = Foo { x :: Int } test :: Foo -> Foo test foo = foo { .. } }}} When loaded, it complains about the empty record update of `foo`, instead of complaining about `..' being used during an update. {{{ GHCi, version 7.8.3: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done. Loading package integer-gmp ... linking ... done. Loading package base ... linking ... done. [1 of 1] Compiling Test ( test.hs, interpreted ) test.hs:8:16: Empty record update of: foo Failed, modules loaded: none. }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/9437> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #9436: Confusing error message with RecordWildCards

#9436: Confusing error message with RecordWildCards -------------------------------------+------------------------------------- Reporter: elliottt | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Keywords: | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Unknown | Type of failure: Blocked By: | None/Unknown Related Tickets: | Test Case: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- When using the RecordWildCards extension, a confusing error message is given when the constructor name is invalid. For example, this module: {{{ {-# LANGUAGE RecordWildCards #-} module Test where data T = T { x :: Int } f :: T -> Int f T' { .. } = x + 1 }}} yields two error messages. The first is about the constructor T' not being in scope, and the second is a confusing message about how `..' is not valid in a record pattern: {{{ GHCi, version 7.8.3: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done. Loading package integer-gmp ... linking ... done. Loading package base ... linking ... done. [1 of 1] Compiling Test ( Test.hs, interpreted ) Test.hs:8:3: Not in scope: data constructor ‘T'’ Perhaps you meant ‘T’ (line 5) Test.hs:8:3: You cannot use `..' in a record pattern Failed, modules loaded: none. }}} It seems like the second error should be left out in this case, as it's enough to report that the name isn't in scope. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/9436> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
