I'm pleased to announce the release of ghc-mod 5.4.0.0! What's new? =========== * Stack support After countless requests ghc-mod now finally has first class Stack support. This should mostly Just-Work^TM there is one caveat though if `dist/setup-config` exists in a Cabal-project directory ghc-mod will continue using cabal-install instead of Stack so if you want to use Stack instead simply remove that file or the whole directory. You also need at least Stack version 0.1.4.0 for this to work. * Support for unsaved files Nikolay Yakimov (@lierdakil) has contributed support for remapping files in a project to temporary files so that the frontend can use these to communicate unsaved file contents to ghc-mod. This is currently supported by Atom's ide-haskell and ghc-mod own Emacs frontend. If you're using a different frontend you should probably nudge the maintainer to get this supported. * Massive slowdown has been fixed A bug causing recompilation checking to be skipped, introduced in v5.3.0.0, has been fixed and ghc-mod should be as responsive as `:reload` in ghci again. * Fixed `Cannot add module to context: not interpreted` When compilation output from a `cabal build` run were present in `dist/` ghc-mod would in certain cases throw this error. This bug was introduced in v5.3.0.0 and has now been fixed. What is ghc-mod? ================ ghc-mod is both a backend program for enhancing editors and other kinds of development environments with support for Haskell and a library for abstracting the black magic incantations required to use the GHC API in various environments, especially Cabal projects. The library is used by ambitious projects like HaRe[1] and mote[2]. Getting ghc-mod =============== GitHub: https://github.com/kazu-yamamoto/ghc-mod Hackage: http://hackage.haskell.org/package/ghc-mod Editor frontends: - Emacs (native): https://github.com/kazu-yamamoto/ghc-mod https://github.com/iquiw/company-ghc - Vim: https://github.com/eagletmt/ghcmod-vim https://github.com/eagletmt/neco-ghc - Atom: https://github.com/atom-haskell/ide-haskell https://github.com/andyfriesen/Helium Known issues ============ ghc-mod's `case`, `sig` and `refine` commands still do not work properly with GHC 7.10 (See https://github.com/kazu-yamamoto/ghc-mod/issues/438). Unless someone volunteers to fix this issue I will work towards repacing the features using mote[2] instead as the current code is, from my point of view, unmaintainable.
