Horrible elisp hack to keep flymake from confusing Merb, Rails, etc.

rails.el

;; Hack up emacs-rails/flymake integration to make autotest happy

;; adapted from flymake.el
(defun abg-flymake-create-temp-inplace-without-ext (file-name prefix)
  (unless (stringp file-name)
    (error "Invalid file-name"))
  (or prefix
      (setq prefix "flymake"))
  (let* ((temp-name (concat (file-name-sans-extension file-name) "." prefix)))
    (flymake-log 3 "create-temp-inplace: file=%s temp=%s" file-name temp-name)
    temp-name))

;; redefine to use my custom temp buffer naming method
(defun flymake-ruby-init ()
  (condition-case er
      (let* ((temp-file (flymake-init-create-temp-buffer-copy
                         'abg-flymake-create-temp-inplace-without-ext))
             (local-file  (file-relative-name
                           temp-file
                           (file-name-directory buffer-file-name))))
        (list rails-ruby-command (list "-c" local-file)))
    ('error ()))
