[erlang-questions] Autosaving *.erl in emacs before compilation

[Roberto Saccon]

thanks, however I get an error when I use define-key erlang-mode-map
when loading emacs:

  Wrong type argument: keymap, nil

everything works fine with global-set-key or with define-key and just
reloading the ermacs preferences file.

I also added a bit of elisp for defining a project and using the
projects Emakefile for compiling



(setq erlang-project "~/path/my-default-project")

(defun set-erlang-project (erlang-project-new)
  (setq erlang-project erlang-project-new))

(defun emakefile ()
  (shell-command
    (concat
      (concat
        (concat "cd " erlang-project) "; erl -make"))))

(define-key erlang-mode-map [f13] ;; gives  error when starting emacs,
don't know why
;;(global-set-key [f13]
  (lambda ()
    (interactive)
    (progn
      (save-buffer)
      (emakefile)
      (erl-reload-modules (erl-target-node)))))



Anybody knows a better way to find the directory of the Emakefile,
e.g. stepping upwards until found (my sourcefiles are in src and
subfolders) ?  I am an absolute beginner with elisp.

regards
