#9642: LANGUAGE pragma synonyms -------------------------------------+------------------------------------- Reporter: dreixel | Owner: Type: feature | Status: new request | Milestone: Priority: normal | Version: 7.9 Component: Compiler | Keywords: Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Unknown Unknown/Multiple | Blocked By: Type of failure: | Related Tickets: None/Unknown | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by jstolarek): Are you aware of the possibility of specifying extensions in package's `.cabal` file? Here's an example: {{{ library hs-source-dirs: src exposed-modules: ... build-depends: ... extensions: BangPatterns EmptyDataDecls FlexibleContexts FlexibleInstances ... }}} This addresses the issue of code duplication. It does not address auto- enabling of LANGUAGE extensions for modules that import a package. Personally I don't like the idea of having extensions automatically (and implicitly) enabled without my knowledge just because I imported a module. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9642#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
