;; mew-edebug.el --- Help for using edebug for macros in Mew

;; Author:  Sen Nagata <sen@eccosys.com>
;; Created: Nov 11, 2001
;; Version: 0.3

;; Set-up:
;;
;;   Put this file somewhere in your `load-path' and the following in
;; your .emacs:
;;
;;     (add-hook 'mew-init-hook
;;               '(lambda ()
;;                  (require 'mew-edebug)))
;;
;;   Upon instrumenting a function with `edebug-defun',
;; `mew-edebug-macro-init' will be run to instrument Mew macros.

;; Issues:
;;
;;   I've tested many of the macros below with edebug. Although most
;; appear to work, I experienced problems with some
;; (e.g. `mew-time-rfc-*').  I don't know what the problem is yet, but
;; my current suspicion is that it has something to do with
;; `defsubst'.

;;; Code:

(require 'mew)

This function should be invoked before instrumenting a function for
use with edebug."
  (interactive)

      (setq macro-names (cdr macro-names)))))

;; instrument Mew macros when edebug is used
(add-hook 'edebug-setup-hook
	  '(lambda ()
	     (mew-edebug-macro-init)))

(provide 'mew-edebug)
