How to shorten urls displayed in text version of mail in Gnus

How to shorten urls displayed in text version of mail in Gnus

[Narendra Joshi]

Hi,

I have configured Gnus to try to display mail with the `text/plain`
version if available. 

A lot of mail happens to have very long URLs that I would like to
shorten while displaying them in the Article buffer. It would be great
if there is something in Gnus that does this already. Is there any
function to wash the article buffer and shorten the text displayed for
URL present in it?


Best,
--

I am looking for shortening the url using an external service. I would like
the text displayed for the url to not take a lot of space. I have gone
through the washing documentation but nothing seems to cover my use case.

Check out the Emacs-wiki suggestion and the MELPA
pack :)

Here are two functions that replace long URLs with the string
"URL" and make them clickable (<ENTER>):

(defun gnus-buttonize-and-shorten ()
  (interactive)
  (progn
    (goto-char (point-min))
    (while (re-search-forward
	    "\\(https*://[-~_a-zA-Z0-9][-~_\\.a-zA-Z0-9/]*\\)"
	    (point-max) t)
      (let* ((start (match-beginning 0))
	     (end (match-end 0)))
	(message "%d %d" start end)
	(goto-char start)
	(let ((thisurl (thing-at-point 'url)))
	  (kill-region start end)
	  (insert-text-button "URL"
		'url thisurl
		'action (lambda (btn)
		  (browse-url (button-get btn 'url)))
		))
	(goto-char (+ start 1))))))

(defun gnus-wash-long-urls ()
  (interactive "")
  (gnus-summary-select-article)
  (gnus-eval-in-buffer-window gnus-article-buffer
    (let ((inhibit-read-only t))
      (save-excursion
	(save-restriction
	(gnus-buttonize-and-shorten))))
  (gnus-treat-article nil)))

A better approach would be to use the button mechanism of Gnus
and set the text to something different.  But I did not find [1]
any option to set the button text.
