Forcing haskell-indent-mode over haskell-indentation-mode in haskell-mode 2.7?

I'm an Emacs user with no skills with regards to configuring the editor. After I upgraded from haskell-mode 2.4 to 2.7, I've noticed two changes:

• Indentation is different somehow, in a way I don't quite like. I can't quite put my finger on what it is.
• More importantly: If I have cua-mode enabled and highlight a block of text, backspace/delete does not delete the entire block, just the previous/next character from my marker.

I see that haskell-mode 2.7 uses the minor mode haskell-indentation-mode by default, w开发者_如何转开发hile 2.4's behaviour has been preserved in the form of haskell-indent-mode. If I first turn off the former, and then on the latter, the behaviour I want is restored (i.e. indentation feels like before, and backspace/delete deletes highlighted blocks).

I can't, however, get this to happen automatically whenever I open a file with a .hs suffix. I've tried various things resembling

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

and the likes of it, but I either end up with the standard mode or with plain haskell-mode without indent and doc.

Any ideas?

Solution (thanks to nominolo):

(remove-hook 'haskell-mode-hook 'turn-on-haskell-indent)
(remove-hook 'haskell-mode-hook 'turn-on-haskell-indentation)
(add-hook 'haskell-mode-hook 'my-haskell-mode-hook)
(defun my-haskell-mode-hook ()
   (haskell-indentation-mode -1) ;; turn off, just to be sure
   (haskell-indent-mode 1)       ;; turn on indent-mode
   )

The best way to configure such things is by writing a custom hook:

(add-hook 'haskell-mode-hook 'my-haskell-mode-hook)

(defun my-haskell-mode-hook ()
   (haskell-indentation-mode -1) ;; turn off, just to be sure
   (haskell-indent-mode 1)       ;; turn on indent-mode

   ;; further customisations go here.  For example:
   (setq locale-coding-system 'utf-8 )
   (flyspell-prog-mode)  ;; spell-checking in comments and strings
   ;; etc.      

   )

You could also stick an anonymous function in there, but having a named function is easier if you want to experiment with some settings. Just redefining the function (and re-opening a Haskell file) will give you the new behaviour.
