#13844: Surprising behavior with CPP extension -------------------------------------+------------------------------------- Reporter: deech | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- The CPP language extension performs macro substitutions in Haskell comments. I see why it does but it seems like eliding the comments before pre-processing would be less surprising. Eg. compiling: {{{#!hs {-# LANGUAGE CPP -#} -- | Some folder foo/bar/* }}} gives the error: {{{ error: unterminated comment -- | Some folder foo/bar/* }}} because the `/*` in the comment is interpreted as starting a C comment. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13844 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
