Hello, I upgrade my emacs configuration with latest ghc-mod and all of sudden nothing works (again). When I try to load a .hs file from a project I got the first line highlighted with the error "cannot satisfy -package spec" and I cannot got type, info or doc from that file. Also I do not have anymore syntax errors highlighting I used to see. Any help greatly appreciated. I would also appreciate any pointer explaining how to setup and maintain a proper Haskell dev environment. Haskell is not the language I use at day work but I have been using it for years and every so often my emacs configuration is broken and I have a hard time getting it back to sane state. Thanks in advance Arnaud Here is my emacs configuration: ;; haskell coding (require 'haskell-mode) (require 'haskell-cabal) (autoload 'ghc-init "ghc" nil t) (add-hook 'haskell-mode-hook (lambda () (ghc-init))) (eval-after-load "haskell-mode" '(progn (define-key haskell-mode-map (kbd "C-,") 'haskell-move-nested-left) (define-key haskell-mode-map (kbd "C-.")
