Hello emacsen users,

Here is a setting to check your Haskell code /on-the-fly/ with 'flymake-mode'.

(require 'flymake)

;; flymake for Haskell (defun flymake-Haskell-init () (flymake-simple-make-init-impl 'flymake-create-temp-with-folder-structure nil nil buffer-file-name 'flymake-get-Haskell-cmdline)) (defun flymake-get-Haskell-cmdline (source base-dir) (list "ghc" (list "--make" (concat "-i" base-dir) source))) (push '(".+\\.hs$" flymake-Haskell-init) flymake-allowed-file-name-masks) (push '(".+\\.lhs$" flymake-Haskell-init) flymake-allowed-file-name-masks) (push '("^\\(.*\\):\\([0-9]+\\):\\([0-9]+\\): \\(.*\\)$" 1 2 3 4) flymake-err-line-patterns)

The 'flymake-mode' has been developed at http://flymake.sourceforge.net/ Emacs22 has this mode already.

dons recommends to me at IRC to write this code into the wiki, however, I don't know where we should put the snippet.

You can watch a short demo at the following blog: http://madscientist.jp/~ikegami/diary/20071108.html#p01

I have some complaints though it works: - it's slow (hmm)

Try using: (defun flymake-get-haskell-cmdline (source base-dir) `("ghc" ("--make" "-fno-code" ,(concat "-i" base-dir) ,source))) This avoids any kind of code-generation, so only syntax and types are checked.

- error and warning seems not distinguished (we may have to modify 'flymake-err-line-patterns') Any comment is appreciated.

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.

Best regards, Ike

P.S. I like vi-clone, such as vim, too. ;-) _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
