missing link in the view buffer

[Emilio Torres Manzanera]

Hello,

I have received this message with a link in the text , but this link
does not appear in the view buffer.
Any solution?
Thanks,
Emilio

When showing html messages, mu4e does html->text conversion; either in
emacs or using some external program; see the variable
`mu4e-html2text-command'.

If that conversion does not preserve the link as something that can be
recognized as an url, there is not much we can do, unfortunately...

Best wishes,
Dirk.

Hi Dirk,

you are right, I am using
(setq mu4e-html2text-command "html2text -utf8 -width 72")
and it seems that the conversion eats the link.

Would you please implement an option to toggle the view between plain
format and html format? For instance, pressing key 'v' converts the
body of the mail into a browser buffer (browse-url-of-buffer or
similar function)

Is it possible?
Thanks in advance.
Emilio

You can use the actions system for this; below, a bit hackish way using
'mu extract' to view a message in an external web browser:

---
(defun mu4e-action-view-in-browser (msg)
"Hack to view the html part for MSG in a web browser."
(let* ((shellpath (shell-quote-argument (mu4e-msg-field msg :path)))
(partnum
(shell-command-to-string
(format "%s extract %s | grep 'text/html' | awk '{print $1}'"
mu4e-mu-binary shellpath))))
(unless (> (length partnum) 0)
(error "No html part for this message"))
(call-process-shell-command
(format "cd %s; %s extract %s --parts=%s --overwrite --play"
(shell-quote-argument temporary-file-directory)
mu4e-mu-binary shellpath (substring partnum 0 -1)))))

(add-to-list 'mu4e-view-actions
'("View in browser" ?v mu4e-action-view-in-browser) t)
---

Now, 'a v' in the view should do the trick. If you want to view things
inside emacs (e.g, using w3m), I guess you could adapt the latter part
of the function. *Left as an exercise for the reader*

I have some ideas about making this less hacky; stay tuned.

Best wishes,
Dirk.

It is a fantastic solution! It works very nice. Thanks!
I provide a quick and less elaborate function that does a similar
result.

(defun mu4e-view-in-browser ()
"View the body of the message in a web browser."
(interactive)
(let (msg txt html)
(setq msg (mu4e-message-at-point t))
(setq txt (plist-get msg :body-txt))
(setq html (plist-get msg :body-html))
(with-temp-buffer
(when (> (length html) 0)
(insert html))
(when (> (length txt) 0)
(insert txt))
(browse-url-of-buffer))))

I tried both scripts and they work fine, but Firefox renders the file as
plain text, not HTML. I found a workaround (Force HTML bookmarklet [1])
but I was wondering if there is a solution that would automatically
achieve this --- eg save the temporary file with a html extension.

Best,

Did you try? Something like should work:

--
(defun mu4e-action-view-in-browser-2 (msg)

"View the body of the message in a web browser."

(let ((html (mu4e-msg-field msg :body-html))
(tmpfile (format "%s/%d.html" temporary-file-directory (random))))
(unless html (error "No html part for this message"))
(with-temp-file tmpfile
(insert
"<html>"
"<head><meta http-equiv=\"content-type\""
"content=\"text/html;charset=UTF-8\">"
html))
(browse-url (concat "file://" tmpfile))))

(add-to-list 'mu4e-view-actions
'("Browser" ?B mu4e-action-view-in-browser-2) t)
--

Best wishes,
Dirk.

Sorry, I did try, but I still know very little about programming in
Emacs. Could you, by any chance, recommend a good book/tutorial? I
already know CL, I just need to learn to find my way around the the DSL
that is Emacs.

This works fine, thanks!
