* Patch to change mouse binding for html view in gnus

I have w3m installed, and so when Gnus sees an HTML message it is
displayed via w3m.  This is quite nice.

However, if I click on a link in an HTML message rendered this way,
the target is displayed using w3m.  I generally don't want this; I
only use w3m in Emacs for specialized things and in other cases I'd
rather use my external web browser.

This patch changes Gnus to use browse-url rather than w3m for links in
buffers it renders.

I don't know.  Personally I think this is a good default -- people who
want to browse extensively in Emacs can set their
browse-url-browser-function.

Maybe there are people who want to usually use an external browser but
then browse using w3m from gnus.  That seems weird to me :), but if
such people exist then, yeah, this should be customizable.

I'm not sure if doing this unconditionally is a good idea.  Shouldn't

Isn't it sufficient to use the following?

(setq w3m-goto-article-function #'browse-url)

This is used only when the `w3m-safe-view-this-url' command is
invoked, and normally the `w3m-safe-view-this-url' command is
bound to a certain key only in html articles.

I'm afraid I'm not a w3m expert (or a gnus expert for that matter :-).
If this is what you would prefer I am happy to send a new patch.
Just let me know.

Tom

I recalled I wrote the same suggestion to you last month. ;-)
See: http://news.gmane.org/group/gmane.emacs.w3m/thread=6852

TSUCHIYA Masatoshi implemented this variable in Jan 2004 for the
other purpose (to bind it to a certain Lisp function in
nnshimbun.el[1]), but it is just the thing for people like you.

Though I don't represent a majority (because I am a member of
the emacs-w3m team), I am satisfied with the nil value of this
variable.  I've set `w3m-make-new-session' to t in order to make
emacs-w3m pop a new tab up when Gnus (or other) requires to
visit a web page.  There is no much case for which I want to use
an external browser.  In such a case, I will type `M' in the
emacs-w3m buffer.  Anyway, I don't think it is necessary to set
it to a certain value in Gnus.

Sorry, I misunderstood that message.  I didn't realize that
w3m-goto-article-function was solely for this purpose -- I thought it
was more generic, and thus needed to be set buffer-local.

The reason I think this patch is needed is that I've already
configured Emacs to visit URLs the way I like.  I was surprised to
find that I had to make another modification, in a different and more
obscure (w3m-goto-article-function is not customizable) place to get
the effect I want.

If you do all your browsing in Emacs then you probably already have
browse-url-browser-function set as you like...

I noticed `w3m-goto-article-function' hasn't been made up as a
user option, so I've made it customizable in the emacs-w3m CVS
trunk yesterday.  Feel free to set it to a Lisp function you
like, but I noticed there is a limitation a bit (because it was
introduced for a particular purpose first).  That is the function
set should return a non-nil value.  Though `browse-url' seems to
return a non-nil value normally, it is better to ensure it.  For
this reason, I recommend using the function form

(lambda (url) (browse-url url) t)

rather than just using `browse-url'.

I leave all those as the default and have no problem (Firefox
happens to be used by default).  I don't always necessarily use
emacs-w3m.   I use Firefox when purchasing something, manipulating
my bank account... ;-)

I've improved it so that just `browse-url' may work no matter
what it returns (in the emacs-w3m CVS trunk).  So, you may use
the one that I suggested first.

Katsumi> rather than just using `browse-url'.

I tried:

(setq w3m-goto-article-function (lambda (url) (browse-url url) t))

but this fails:

  fboundp((lambda (url) (browse-url url) t))
  w3m-safe-view-this-url()
  w3m-mouse-safe-view-this-url((mouse-2 (#<window 1388 on *Article*> 436 (111 . 209) -81415166 nil 436 (18 . 16) nil (3 . 1) (6 . 13))))
  call-interactively(w3m-mouse-safe-view-this-url)

The reason is this code in w3m-safe-view-this-url:

     (url (or (when (fboundp w3m-goto-article-function)
		(funcall w3m-goto-article-function url))

So to make this work I had to make a new defun and then setq
w3m-goto-article-function to that.  Using an anonymous function won't
work, due to the fboundp.

I didn't look to see whether your patch here fixed this problem or
not, I just thought I'd post in case anybody else is trying to set
things up this way.

Ok.  I suppose this response means you are not swayed by my argument
that users should only have to customize in a single place.

The code should use `functionp' instead of `fboundp'.

Yup.  I've fixed it about a week ago in the emacs-w3m CVS trunk[1].
Furthermore, I also made a change so that just `browse-url' rather
than such a lambda form for `w3m-goto-article-function' may work[2].

That is that at least I am only not motivated to do that.
Neither this represents the emacs-w3m team nor I am a chief of
the team.  You can contact the team at a suitable place, i.e.,
the emacs-w3m mailing list for example.
