html rendering in gnus

html rendering in gnus

[Jay Bromley]

Hello,

I've recently started using gnus for news and mail and have a couple of
questions about HTML rendering in mails and links.

First, I'd like to use elinks to do my HTML mail rendering. Right now I set
mm-text-html-renderer to lynx and have lynx symlinked to elinks. This is a
kludge though, as the lynx -> elinks thing is bogus and I had to edit
mm-view.el to eliminate a flag that elinks doesn't understand. I noticed there
is an option to use a user-defined function and I'd like to write a function
to use elinks with the appropriate flags, but I've no idea what this function
should look like. I (think I) have a sufficient grasp on Elisp, but I don't
know anything about what the function takes and what it should evaluate to. I
read the Gnus manual, but seemed to miss any info there might be about this.
Pointers to docs or template functions would be very much appreciated.

For the second question, my currently kludged system renders HTML fine, but I
can't click on links in mail messages and have it bring up the page in my real
browser. I'm not quite sure why, as this works great with links in news
articles. I'm a bit confused on this, as I thought gnus would treat mails and
news articles the same. Is there some other variable or hook I need to set to
get this behavior?

Thanks for any help in advance, regards.

Thank you, adding elinks to mm-text-html-renderer-alist occurred to me after
looking at mm-view.el, but I forgot the (require 'mm-view), so it didn't
work. This is exactly what I needed.

Regards.

Thanks for your help : it works here (slowly) now too. I had this in my
.gnus.el:

(require 'w3m-load)
(setq mm-text-html-renderer 'w3m)
;;(setq mm-inline-text-html-with-w3m-keymap nil)

with the last line not commented out : no idea why it was there -
probably just copied the lines from someone else ages ago.

Thanks again.

When using w3m you need put this in .gnus.el (what I assumed, you did):
     
     (setq mm-text-html-renderer 'w3m)

Then in a text/html-part a simple RET (bound to 'w3m-safe-view-this-url)
would do.

In a text/plain-part M-x w3m RET would check the string under point as a
possible url to visit.


At least this is the way it works here.

That opens the welcome to w3m info page. Im sorry, but I'm confused
now. I guess  its following w3m-home-page and not the underlying link.

Ok, this works - but what w3m function to open this link in the emacs
buffer? Cant seem to get any of the mentioned ones to
work. Interestingly the link isnt shown in the w3m buffer as underlined
: but w3m-view-url-with-external-browser does indeed "pick up" the html
link and opens it successfully in another browser. What do I need for
w3m to do this in the article buffer?

Its ok, I did this in .gnus.el and it seems to work fine

(define-key gnus-article-mode-map (kbd "<f1>") 'w3m-view-url-with-external-browser)

Any comments on whether this is better achived appreciated.

HTML rendering in gnus

[Hadron Quark]

Somthing is installed which gives a text rendering of html emails : but
links do not work. In normal emails any http link can be opened in a
seperate browser by tabbing to it and hitting enter (browse-url) which
in turns opens a firefox tab.

How do I find out (a) whats rendering my html emails and (b) get it to
open links in either a new buffer or an external browser.
