I recently asked on this list wether you'd be interested in adding goto-addr to XEmacs but got no reply. I went ahead and so now I'm putting my mouth where the code is. :) goto-addr.el is currently part of Emacs and uses overlays. I've made the necessary changes in the source. If you are interested, I'll submit the changes back to the Emacs maintainer. I got the latest goto-addr.el from him to do exactly this, so I don't expect any problems on the Emacs side. In order to test, I've used a buffer with a mail address and a URL, like this: alex(a)gnu.org and http://www.gnus.org/ and I evaluated the following code: (load-file "~/elisp/goto-addr/goto-addr.el") (goto-address) (setq mail-user-agent 'sendmail-user-agent) This allowed me to use mouse-2 or C-c RET to open Netscape (this depends on your browse-url setup) or create a mail buffer (and this depends on your compose-mail setup). Beyond requiring 'overlay, there is other compatibility cruft as well. Here's the entire list of XEmacs related code. I've tried to find equivalents for line-beginning-position and line-end-position in the XEmacs Lispref manual but couldn't find anything. A defalias would be nicer, of course. And if you know of a simple workaround to the mouse-2 / button2 problem, please let me know. ;; XEmacs needs the following definitions. (unless (fboundp 'overlays-in) (require 'overlay)) (unless (fboundp 'line-beginning-position) (defun line-beginning-position () "Compatibility function." (save-excursion (beginning-of-line) (point)))) (unless (fboundp 'line-end-position) (defun line-end-position () "Compatibility function." (save-excursion (end-of-line) (point)))) (unless (fboundp 'match-string-no-properties) (defalias 'match-string-no-properties 'match-string)) (defvar goto-address-highlight-keymap (let ((m (make-sparse-keymap))) (if (featurep 'xemacs) (define-key m (kbd "<button2>") 'goto-address-at-mouse) (define-key m (kbd "<mouse-2>") 'goto-address-at-mouse)) (define-key m (kbd "C-c RET") 'goto-address-at-point) m) "keymap to hold goto-addr's mouse key defs under highlighted URLs.") Anyway, I'd appreciate some feedback. I am not on the xemacs-beta mailing list, so please include me in the CC. :) Alex.
