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-.") 'haskell-move-nested-right)

(define-key haskell-mode-map (kbd "C-c v c") 'haskell-cabal-visit-file)

(define-key haskell-mode-map (kbd "C-c C-c") 'haskell-compile)

(define-key haskell-mode-map (kbd "C-x C-d") nil)

(setq haskell-font-lock-symbols t)))

(add-hook 'haskell-mode-hook 'turn-on-haskell-decl-scan)

(add-hook 'haskell-mode-hook 'turn-on-haskell-indentation)

(eval-after-load "which-func"

'(add-to-list 'which-func-modes 'haskell-mode))

(eval-after-load "haskell-cabal"

'(define-key haskell-cabal-mode-map (kbd "C-c C-c") 'haskell-compile))
