Hi, Thanks Thomas for your advice. The speed is improved very much. The latest code about Flymake Haskell will be developed and discussed on EmacsWiki:FlymakeHaskell. http://www.emacswiki.org/cgi-bin/emacs/FlymakeHaskell However, we can continue the discussion via email, too. Thomas wrote:

It seems you need multi-line pattern matching. Note that shim already can do this, but it doesn't do it automatically. Unfortunately, shim chokes on files that need pre-processing. There's probably a way to integrate these two.

You are right; the multi-line pattern matching is needed. However, I failed some tries, and finally I invoked ghci from Emacs as I did usually. Anyone helps? I don't know shim's work. Gwern wrote:

Is there further setup needed?

I think your setting maybe wrong.

(defun flymake-Haskell-init () (interactive) ; this line should be removed brabra

I didn't test Gwern's setting on XEmacs, however I wish it helps. Best wishes, Ike
