#3384: Add HsSyn prettyprinter tests -------------------------------------+------------------------------------- Reporter: igloo | Owner: Type: task | Status: new Priority: normal | Milestone: ⊥ Component: Test Suite | Version: 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 alanz): The current AST does not allow faithful reproduction of a context with extra parens around it. So {{{#!hs foo :: (Show a) => a -> String }}} and {{{#!hs foo :: ((Show a)) => a -> String }}} produce the same AST fragment. `ghc-exactprint` works around this by using the API Annotations. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/3384#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
