I'm an Opera user and recently switched from XEmacs to FSF Emacs. The
XEmacs version of browse-url.el (in the mail-lib package) has support for
Opera; I was wondering if it might be possible to fold that into the FSF
version?
I just copied the Opera code from the XEmacs version and it seemed to work
nicely. The XEmacs file has the following copyright notice:

which suggests that the code is already assigned to the FSF, so it could
be included in GNU Emacs.
I attach the XEmacs version of browse-url.el, and my modified version of
FSF Emacs 21.3.1's browse-url.el. Let me know if I can help in any other
way.

;;; Commentary:
;; This package provides functions which read a URL (Uniform Resource
;; Locator) from the minibuffer, defaulting to the URL around point,
;; and ask a World-Wide Web browser to load it. It can also load the
;; URL associated with the current buffer. Different browsers use
;; different methods of remote control so there is one function for
;; each supported browser. If the chosen browser is not running, it
;; is started. Currently there is support for the following browsers,
;; some of them probably now obsolete:
;; Function Browser Earliest version
;; browse-url-netscape Netscape 1.1b1
;; browse-url-mosaic XMosaic/mMosaic <= 2.4
;; browse-url-cci XMosaic 2.5
;; browse-url-w3 w3 0
;; browse-url-w3-gnudoit w3 remotely
;; browse-url-iximosaic IXI Mosaic ?
;; browse-url-lynx-* Lynx 0
;; browse-url-grail Grail 0.3b1
;; browse-url-mmm MMM ?
;; browse-url-generic arbitrary
;; browse-url-default-windows-browser MS-Windows browser
;; browse-url-gnome-moz GNOME interface to Mozilla
;; browse-url-kde KDE konqueror (kfm)
;; [A version of the Netscape browser is now free software
;; <URL:http://www.mozilla.org/>, albeit not GPLed, so it is
;; reasonable to have that as the default.]
;; Note that versions of Netscape before 1.1b1 did not have remote
;; control. <URL:http://www.netscape.com/newsref/std/x-remote.html>.
;; Browsers can cache Web pages so it may be necessary to tell them to
;; reload the current page if it has changed (e.g. if you have edited
;; it). There is currently no perfect automatic solution to this.
;; Netscape allows you to specify the id of the window you want to
;; control but which window DO you want to control and how do you
;; discover its id?
;; If using XMosaic before version 2.5, check the definition of
;; browse-url-usr1-signal below.
;; <URL:http://www.ncsa.uiuc.edu/SDG/Software/XMosaic/remote-control.html>
;; XMosaic version 2.5 introduced Common Client Interface allowing you
;; to control mosaic through Unix sockets.
;; <URL:http://www.ncsa.uiuc.edu/SDG/Software/XMosaic/CCI/cci-spec.html>
;; William M. Perry's excellent "w3" WWW browser for
;; Emacs <URL:ftp://cs.indiana.edu/pub/elisp/w3/>
;; has a function w3-follow-url-at-point, but that
;; doesn't let you edit the URL like browse-url.
;; The `gnuserv' package that can be used to control it in another
;; Emacs process is available from
;; <URL:ftp://ftp.splode.com/pub/users/friedman/packages/>.
;; Grail is the freely available WWW browser implemented in Python, a
;; cool object-oriented freely available interpreted language. Grail
;; 0.3b1 was the first version to have remote control as distributed.
;; For more information on Grail see
;; <URL:http://grail.cnri.reston.va.us/> and for more information on
;; Python see <url:http://www.python.org/>. Grail support in
;; browse-url.el written by Barry Warsaw <bwarsaw@python.org>.
;; MMM is a semi-free WWW browser implemented in Objective Caml, an
;; interesting impure functional programming language. See
;; <URL:http://pauillac.inria.fr/%7Erouaix/mmm/>.
;; Lynx is now distributed by the FSF. See also
;; <URL:http://lynx.browser.org/>.
;; Free graphical browsers that could be used by `browse-url-generic'
;; include Chimera <URL:ftp://ftp.cs.unlv.edu/pub/chimera> and
;; <URL:http://www.unlv.edu/chimera/>, Arena
;; <URL:ftp://ftp.yggdrasil.com/pub/dist/web/arena> and Amaya
;; <URL:ftp://ftp.w3.org/pub/amaya>. mMosaic
;; <URL:ftp://ftp.enst.fr/pub/mbone/mMosaic/>,
;; <URL:http://perso.enst.fr/~dauphin/mMosaic/> (with development
;; support for Java applets and multicast) can be used like Mosaic by
;; setting `browse-url-mosaic-program' appropriately.
;; I [Denis Howe, not Dave Love] recommend Nelson Minar
;; <nelson@santafe.edu>'s excellent html-helper-mode.el for editing
;; HTML and thank Nelson for his many useful comments on this code.
;; <URL:http://www.santafe.edu/%7Enelson/hhm-beta/>
;; See also hm--html-menus <URL:http://www.tnt.uni-hannover.de/%7Emuenkel/
;; software/own/hm--html-menus/>. For composing correct HTML see also
;; PSGML the general SGML structure editor package
;; <URL:ftp://ftp.lysator.liu.se/pub/sgml>; hm--html-menus can be used
;; with this.
;; This package generalises function html-previewer-process in Marc
;; Andreessen's html-mode (LCD modes/html-mode.el.Z). See also the
;; ffap.el package. The huge hyperbole package also contains similar
;; functions.

;; Help!
;; Can you write and test some code for the Macintrash and Windoze
;; Netscape remote control APIs? (See the URL above).
;; Do any other browsers have remote control?
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;; Usage
;; To display the URL at or before point:
;; M-x browse-url-at-point RET
;; or, similarly but with the opportunity to edit the URL extracted from
;; the buffer, use:
;; M-x browse-url
;; To display a URL by shift-clicking on it, put this in your ~/.emacs
;; file:
;; (global-set-key [S-mouse-2] 'browse-url-at-mouse)
;; (Note that using Shift-mouse-1 is not desirable because
;; that event has a standard meaning in Emacs.)
;; To display the current buffer in a web browser:
;; M-x browse-url-of-buffer RET
;; To display the current region in a web browser:
;; M-x browse-url-of-region RET
;; In Dired, to display the file named on the current line:
;; M-x browse-url-of-dired-file RET
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;; Customisation (~/.emacs)
;; To see what variables are available for customization, type
;; `M-x set-variable browse-url TAB'. Better, use
;; `M-x customize-group browse-url'.
;; Bind the browse-url commands to keys with the `C-c C-z' prefix
;; (as used by html-helper-mode):
;; (global-set-key "\C-c\C-z." 'browse-url-at-point)
;; (global-set-key "\C-c\C-zb" 'browse-url-of-buffer)
;; (global-set-key "\C-c\C-zr" 'browse-url-of-region)
;; (global-set-key "\C-c\C-zu" 'browse-url)
;; (global-set-key "\C-c\C-zv" 'browse-url-of-file)
;; (add-hook 'dired-mode-hook
;; (lambda ()
;; (local-set-key "\C-c\C-zf" 'browse-url-of-dired-file)))
;; Browse URLs in mail messages under RMAIL by clicking mouse-2:
;; (add-hook 'rmail-mode-hook (lambda () ; rmail-mode startup
;; (define-key rmail-mode-map [mouse-2] 'browse-url-at-mouse)))
;; Alternatively, add `goto-address' to `rmail-show-message-hook'.
;; Gnus provides a standard feature to activate URLs in article
;; buffers for invocation of browse-url.
;; Use the Emacs w3 browser when not running under X11:
;; (or (eq window-system 'x)
;; (setq browse-url-browser-function 'browse-url-w3))
;; To always save modified buffers before displaying the file in a browser:
;; (setq browse-url-save-file t)
;; To get round the Netscape caching problem, you could EITHER have
;; write-file in html-helper-mode make Netscape reload the document:
;;
;; (autoload 'browse-url-netscape-reload "browse-url"
;; "Ask a WWW browser to redisplay the current file." t)
;; (add-hook 'html-helper-mode-hook
;; (lambda ()
;; (add-hook 'local-write-file-hooks
;; (lambda ()
;; (let ((local-write-file-hooks))
;; (save-buffer))
;; (browse-url-netscape-reload)
;; t) ; => file written by hook
;; t))) ; append to l-w-f-hooks
;;
;; OR have browse-url-of-file ask Netscape to load and then reload the
;; file:
;;
;; (add-hook 'browse-url-of-file-hook 'browse-url-netscape-reload)
;; You may also want to customise browse-url-netscape-arguments, e.g.
;; (setq browse-url-netscape-arguments '("-install"))
;;
;; or similarly for the other browsers.
;; To invoke different browsers for different URLs:
;; (setq browse-url-browser-function '(("^mailto:" . browse-url-mail)
;; ("." . browse-url-netscape)))

I recall a discussion about this earlier, when someone proposed a
patch for Opera, and that someone didn't think Emacs should support
non-free browsers like Opera. The XEmacs folks didn't have that
concern, though, so the patch was applied to that version of
browse-url.el.
If you think this decision should be reconsidered, for Emacs, I think
it has to be discussed on emacs-devel@gnu.org.

I don't have the stomach for such a discussion right now. Having to argue
to get a patch that is acknowledged to be technically and legally fine
into a free software package against philosophical objections seems
rather contrary to much of the spirit of free software.
I supply bug reports and patches to free software projects all the time.
I'm quite happy to have them questioned on technical grounds; similarly,
if I find some code that would be useful in a free software project, it's
reasonable for the maintainers to enquire as to its provenance, especially
in a project like GNU where great pains are taken to ensure that the
software will always be legally free, by being owned by the FSF.
But this case is neither. It implies that the FSF not only wants me to use
free software, but is happy to use its considerable leverage (i.e. much of

web browser or we won't support you. As it happens, Opera is the one
non-free bit of software that I am aware of using regularly. I use it
because it works better for me than the alternatives. I wish it weren't
so; I find free software more satisfying on philosophical grounds, and in
general of higher quality and better supported than non-free software. But
a couple of years ago I didn't really see a better choice than Opera, and
I switched to it. I'm hoping that Mozilla Firebird, when it goes stable,
will replace Opera; I encourage other people to use Mozilla. But I don't
see what my (free!) choice of browser has to do with the authors of GNU
Emacs.
Funnily enough, I wouldn't even be involved in this discussion if it

that I've had to throw several kb of script at before it can open URLs in
my web browser the way I want: in most programs, I just have to configure
a string that looks something like
foobrowser -remoteWindow("%u")

problem, but it adds injury to insult [sic].

If someone remember more details about the prior Opera browse-url
discussion, that would be useful. I tried searching a little, but
didn't find anything. I might have just imagined it... No, I found
it, here's a link:

Sorry, browse-url should support any browser, just use the
'browse-url-generic' browser and specify the name of the application
in `browse-url-generic-program'.
Giving an explicit reference to a commercial product is a step
further, and I can understand why a free program might not want to do
that.

Can you describe what your script does? Using the generic URL
browser, and then customizing `browse-url-generic-program' and
`browse-url-generic-args' seems rather flexible. I'm not sure how it
can be made more flexible.

The free software movement is based on the recognition that non-free
software is antisocial and unethical. It is a social problem, and our
work is to solve that problem. Success for us does not mean writing
popular free programs, it means ending the antisocial practice of
distributing non-free software.
Your argument for including this patch seems to be based on a
principle that that technical decisions should be made solely on
technical grounds. That principle is a grave and fundamental error.
It rejects the lessons society learned after the development of
nuclear weapons: that technical decisions must be based on
consideration of social responsibility. GNU derives from an idea of
social responsibility, and we make technical decisions based on that.
We can't tell what programs to use, but helping you use a non-free
program is not part of the GNU Project's mission. I decided before
not to include this code, and I stand by the decision.
Not supporting non-free programs in Emacs is one of the ways we show
we are serious when we say they are unethical. That may not convince
you, but we hope it will convince others.

Restricting the user's choice of what programs he might use for
whatever reasons is also restricting his freedoms.
However, in this case there is no such restriction: you can set
browse-url-generic-program and browse-url-generic-args to support
Opera, and then set browse-url-browser-function to point to
browse-url-generic.
In short: Opera is supported just fine, you just don't have a default
configuration for it distributed with Emacs.
So the question is not whether or not to support Opera (it is
supported via the generic interface), but to offer a default
configuration and cast into code a decision how Opera should be
supported best as considered by the GNU project.
Given that Opera is non-free software, the appropriate choice is to
leave this responsibility with the user.
I would consider the omission of a generic interface an unduly
restriction of the user. But this is not what we are having here.
If you want to configure your browser to be Opera, it will take you
setting 3 configuration variables instead of one, and making the
decision yourself how to call it.
That's tolerable.

I don't understand `several kb of script', but the point is right.
The current mechanism would have been junked if I'd been able to
continue maintaining browse-url.

In most cases, I'd hope you wouldn't have to configure anything.
There should be heuristics to DTRT in common cases, e.g. use
`sensible-browser' (?) in Debian or whatever the environment variable
mechanism was that ESR proposed -- he does write some useful things.
Emacs shouldn't know about the specific browser you're using (except,
perhaps, when you want to run it in an Emacs window). Doing anything
else just clobbers free software users, who surely have more free
browsers available than proprietary ones. It's especially galling
that Emacs on MS Windows (as I understand it) does sort-of DTRT, if
invoking Internet Exploiter could be considered right.
browse-url should still be able to intercept and DTRT with mailto: &c,
of course.

Whatever we decide to support or not support, this does not restrict
the users. Since our software is free, they can change it.
They are never restricted by our technical decisions.
GNU Project policy is that supporting a non-free program is never a
high priority mission, not even when that program is widely used, as
is Microsoft Windows.

The main means you've chosen to end the practice of distributing non-free
software is to distribute free alternatives, so you're not going to be
successful if your programs aren't popular.

I have no such principle. If I had to state anything so dangerous as an
absolute principle, it would be much closer to your position than to the
one you infer. I do believe in proportionality, though: this particular
case (a very small feature) should, in my view be decided pretty much
purely on technical grounds. There are some matters that shouldn't: for
example, using a proprietary markup format instead of HTML for the WWW
would be unethical (as well as plain stupid) however technically superior
it might be.
The principle I lack is that principles are absolute criteria that must
always be applied (in particular, I don't believe that battles are lost
for want of a nail).

I agree completely.

And again, I agree. I probably wouldn't be in the privileged position of
having an affordable computer system almost all of whose operation I can
scrutinise and change, all the while sharing those changes with others and
benefitting from their expertise and ideas, were it not for the efforts of
the FSF on whose software I largely depend.

It's up to the authors of a program what conditions they make on its use
and its development. I expressed my frustration with a particular
decision, but I can't claim that it's wrong. At least in this case I get a
reasoned argument from the authors; with non-free software that would be
the last thing I'd expect.

I think I'm probably more convinced than most; and for all that I don't
entirely agree with your opinion, I'm very glad that someone holds it,
just as I'm also glad that not everyone does.
On second thoughts, I've found the time to look for a solution to this
particular problem in the form of code, which you'll find in another part
of this thread as a response to a message from Dave Love.

I was looking at the length of browse-url.el. I now see that a lot of it
isn't just calling browsers, but the bit that is (especially the support
for particular browsers) is embarrassingly long.
> The current mechanism would have been junked if I'd been able to

I've had a go at reworking browse-url-generic to be useful with more
browsers and simpler to customise.
> In most cases, I'd hope you wouldn't have to configure anything.
:-) Well, browse-url already defaults to htmlview for the generic browser,
which works well for me.
OK, I attach a preliminary rework of browse-url.el. I've done three main
things:
1. In line with what RMS said elsewhere, I've removed support for non-free
browsers. Most of the code in this category was to support old versions of
Netscape. Mozilla and new versions of Netscape are adequately supported by
my new implementation of browse-url-generic.
2. I've removed support for other browsers that can be supported by my new
browse-url-generic, e.g. MMM, Grail, Lynx-in-xterm.
3. I've rewritten browse-url-generic so that browse-url-generic-args is a
string, not a list (I've not redone the other browser support code to be
consistent with this; perhaps it's not worthwhile or even
counterproductive). This string may contain the token __URL__; if so, the
URL given is substituted for it. Otherwise, the URL is added as an extra
final argument. The string is split at spaces to be passed to
start-process.
The reason for using a string rather than a list of args is that it's
easier for users to configure. Slightly more careful parsing of the string
(e.g. respecting quotes when splitting it into individual args) would
solve most remaining problems with that approach.
I'm also sorely tempted to remove the special support for Mosaic, as it's
long and the program is obsolete, but perhaps there are enough users on
older hardware who don't have alternative more modern browsers.
The version of browse-url.el I attach is a modified version of that
supplied with Emacs 21.3.1, and all the modifications are by me (I didn't
use any of the XEmacs code I mentioned before). It's also a little under
half the size of the 21.3.1 version.

If my goal is free speech, then this goal is achieved when everybody
that wants to can speak up. Even if the percentage of those that
actually want to make use of that freedom are few.

On technical grounds, there is no necessity for it. There are
already hooks that make it reasonably easy to get the behavior you
want.
So it is easy enough for the Opera user community to discuss and
propose and implement and distribute what they consider best for
using in connection with Emacs. They just can't rely on the GNU
project to maintain and distribute and recommend such stuff.

Let me add another more down-to-earth argument: if free software
support non-free tools, like Opera in browse-url.el in this example,
it becomes the free software people's work to make it work. The emacs
maintainers have to apply the patches, document it, change the code
whenever the tool changes its API, etc. This takes time, aka money.
It is not clear why Emacs maintainers should donate time to people
that don't give anything back. In some cases Emacs maintainers can do
so when it is easy to do, and makes the users considerably happier.
This seem to be the case for browse-url.el: as far as I recall,
Netscape wasn't free software initially, but browse-url support it.
If Opera Inc. were to donate money for support in browse-el.el, I
would reconsider the situation, and might allow the modification. But
I'm not sure the Emacs maintainers would. In that situation it may be
a good opportunity to push Opera Inc. into using a free license on
their software, instead of donating money. Unless the corporation's
is mainly interested in pursuing non-free software for its own sake,
it may make economical sense for them to re-license their software,
instead of donating money to free software projects for adding Opera
support. Especially if the sum of money would be large. A relicensed
Opera would be better for the free software community, instead of the
Emacs maintainers accepting money for making a certain modification.
So it might actually be better, in the long-term, to even refuse
donations in exchange for certain modifications.
Regarding your modified browse-url.el:
It is very difficult to evaluate your work when you send the entire
file, instead of a patch (use 'diff -u'). In any case, I don't think
anyone has requested removing support for already supported non-free
tools, like Netscape. Also, changing the type of existing variables,
like browse-url-generic-args, may break backwards compatibility, which
I think is a no-no for that kind of variable.

OK, I'll rework and send a diff.

I am glad that our views are closer together than I had realized.
The main means you've chosen to end the practice of distributing non-free
software is to distribute free alternatives, so you're not going to be
successful if your programs aren't popular.
No need to worry. Emacs is popular enough.
I do believe in proportionality, though: this particular
case (a very small feature) should, in my view be decided pretty much
purely on technical grounds.
I try to decide each issue based on its most important consequences,
whether those be technical or social. We should never let the
intermediate goals block our view of the ultimate goal.
Thanks for working on simplifying browse-url.el. I will try to
take a look at the new version soon.

But it's becoming clear to me that here too, it depends. After all, Emacs
supports Windows and Netscape. It's a bit ironic that if you're a non-free
system with a near-monopoly (as Windows is and Netscape was) you can get
support. Opera, as a non-free product, is much less offensive (in
particular, it tries to be standards-compliant, and Opera Software don't
go around foisting new "standards" on the world) but it's too small to be
worth supporting...

Sadly, Opera seem to make most of their money from licensing their
browser.

Attached. The diff is against browse-url.el as shipped with Emacs 21.3.1;
if you'd like it against CVS or something else, please ask.

But it's becoming clear to me that here too, it depends. After all, Emacs
supports Windows and Netscape.
We tell GNU package maintainers that it is their choice whether to
support a non-free system such as Windows. I don't spend time on
Emacs for Windows, but people volunteer to take care of it, so I let
them do it.
It is a strategic decision that having Emacs run on Microsoft Windows
is probably a good idea. Nobody can be completely certain, but
Microsoft Windows has more users than Emacs does.
But it's becoming clear to me that here too, it depends. After all, Emacs

I'm afraid some of this sounds patronizing to me. (I'm sure it's not
meant to be.)
You should be able to find four or five Lisp files devoted to support
of non-free stuff straight off.

I've donated interfaces to non-free stuff because I needed them
(e.g. for debugging tasks gdb couldn't do). There's no obligation on
users to give anything back -- it's free.
Anyhow, the point is that there should be a different interface so
it's _no_ maintenance work to support different browsers. If that
makes it easy to use proprietary ones, so be it, as long as it's easy
for the free ones I want to use.
