Subject: 23.2.50; Include patch for distinguishing between left and right Alt
	keys on OSX
Date: Sat, 2 Oct 2010 16:41:51 +0100

It's not a bug per se, rather a feature request.
Would it be possible to include this patch:
http://lists.aquamacs.org/pipermail/aquamacs-devel/2009-November/003853.html
in Gnu Emacs? It's only relevant for OSX, but makes life easier for
anyone who wants to use Emacs under OSX and uses a keyboard layout that
uses right Alt key as a modifier to input special characters. This is an
Aquamacs patch, and Aquamacs allows this:

;; Make right Meta a system modifier.
(setq ns-right-alternate-modifier nil)

which results in left Alt being interpreted by Aquamacs as Meta, and
right Alt being interpreted by operating system as keyboard
modifier. This allows me to use Polish keyboard layout without resorting
to unusual method of inputting Polish characters. It would be good if
other users, especially those that don't want to use Aquamacs because of
some of its modifications, can use this feature.

I've tried to naively apply this patch to current 23.2 sources, but
failed - apparently it has diverged too much by now. I don't think I
have both skills and time needed to modify this patch, but it looks
relatively simple, provided you know your way around Emacs source code.

Is there a chance to port and include this feature?

Thanks,

KT.

I commited the same functionality in the emacs-23 branch.  The patch you refer 
to makes none mean something else for right alt (follow left alt) than it does 
for the left alt (pass to system).  This is inconsistent, so I kept none to 
mean pass to system, and made a new value, left, to mean follow the left alt key.

Can you please point me to relevant commit, so I can get the right

Use
% bzr branch http://bzr.savannah.gnu.org/r/emacs/emacs-23

to get that branch.  Also see http://savannah.gnu.org/projects/emacs/.
The relevant revno is 100102.

I think it is

  bzr branch bzr://bzr.savannah.gnu.org/emacs/emacs-23

(i.e. without the "r" part and with "bzr" instead of "http").

Well, http: with r works as does bzr: without r.  Take your pick :-).
Maybe bzr is faster if you later are going to update the tree, I haven't 
tested.  For the inital download they are the same (i.e. slow).

Both are correct, albeit the latter is faster, but may not work through
firewalls.

I can confirm it really works as expected. Well, at least as I'd
expect it to work :)
I take it that this change will be included in 23.3?

Yes, that tree will become 23.3.

People who only want the latest revision (ie. not the full history)
can use "bzr checkout --lightweight" instead of "bzr branch" to save
both disk space and transfer time (at least initially, don't know
about updates). Maybe http://savannah.gnu.org/bzr/?group=emacs could
mention this possibility.

Would it be possible to include this patch
http://lists.aquamacs.org/pipermail/aquamacs-devel/2009-December/003890.html
which allows OSX users to set right modifier keys to be (for example)

Can you file a separate bug for this and explicitly spell out what you wish 
without referring to a patch?
