Subject: 24.0.50; NS variant cannot copy to pasteboard correctly
Date: Tue, 20 Jul 2010 12:13:24 +0200

Hello!

Although it obviously works to copy some text in an X client or in a  
Mac OS X application and paste it into the *scratch* buffer it does  
not work to mark some text in any buffer of the NS variant and either  
use the Copy entry from the Edit menu or just press ⌘-C (Cmd-C) and  
insert (paste) it into the X client or a Mac OS X application (the  
name of the application in the  bar only flashes, because some bad  
content, not fitting into the text pane, is held in pasteboard?).

Additionally double-click to mark a word is interpreted as <down- 
mouse-1> <mouse-1>, bound to mouse-drag-region. I don't think that  
this is desirable...

My MacOSX/GNUStep/ObjC, while not quite non-existent, is not amazing.

But it looks to me like src/nsselect.m  needs some adjustment so it can 
handle recent changes to defaults (and N.B. in fact to handle settings 
that have been possible for a long time)

It looks like it has been mapping NSGeneralPBoard (the macosx "normal" 
cut/copy/paste clipboard) to an emulated X11 PRIMARY, when in fact 
NSGeneralPBoard is much more closely analagous to X11 CLIPBOARD.

*** Since x11 emacs is now actually using X11 CLIPBOARD, it is likely 
that the attached  _untested_ but minor patch or something very like it 
is correct on nextstep.

Can you try building an emacs with the patch on macosx?

Note that even with the patch applied, it may not act quite the same as 
before, but that is not necessarily a bug but rather a change.

(N.B. it should be possible to get historical behaviour back (even 
though looking at nsselect.m it was probably a bit odd) by twiddling 
customizations).

N.B. Mouse-drag-region calls mouse-drag-track which calls 
mouse-start-end to _implement_ double-click to mark a word, perhaps not 
intuitively given the name. So does double-clicking nonetheless actually 
mark the word on NS?

Er, actually chunks of lisp/term/ns-win.el likely need rewriting too.
(the repeated use of the phrase "cut buffer" is particularly worrying - 
in X11 terms, that means "obsolete thingy that basically no-one uses, 
replaced by the selections mechanism many years ago").

That previous patch is probably necessary but not sufficient.

Basically someone who knows enough of both X11 and nextstep/macosx needs 
to sort things out.  I guess that just about includes me for these 
purposes, but it isn't something I can sort out during the week, and I 
don't have an extant macosx development environment either (though I 
suppose gnustep is an apt-get away).

Yesterday, at UTC evening, I updated with bzr. The build did not copy.  
Today, after a 'make clean', I applied your patch and re-compiled. No  
change, still copying from the NS variant to other Mac OS X  
applications or X clients does not work. One change happened, when  
pasting what I marked and copied in X11 or a Mac OS X application:

	Quit: "pasteboard doesn't contain valid data"

Maybe the copy&paste code could be made smaller since the X servers in  
Snow Leopard have built-in a synching mechanism with the Mac OS X  
pasteboard and up-to-date X servers in Leopard have it too. Only the  
original Apple X server lacks this, but can be configured to work  
similarly.

Yes, it does. In the beginning I found that this did not copy the word  
to the pasteboard, so I assumed some key binding might have changed,  
but they haven't. A working (and installed in /Applications) copy from  
middle of June describes double-click as the same – and copies the  
word to Mac OS X pasteboard and X11 PRIMARY selection (or XQuartz  
2.5.1 (xorg-server 1.8.99.904) from MacPorts is synching OS X and X11).

Yes, Xquartz is handling syncing - IIUC native NS emacs presently knows 
nothing* of real X11 selections, and only interacts with the NS pasteboard.

The Xquartz on OS X manpage documents a set of options you can use to 
tune _how_ Xquartz syncs the native OS X pasteboard and the X11 
clipboard and/or primary:

http://developer.apple.com/mac/library/DOCUMENTATION/Darwin/Reference/ManPages/man1/Xquartz.1.html


[I haven't yet discovered equivalent tunable settings for Cygwin/X, hope 
they haven't hardcoded something broken.]


* well, gnustep's gui layer, unlike macosx, sits on top of x11, and some 
abstractions may be slightly leaky.

This is not the problem here since I can easily interchange data  
between X clients and Mac OS X applications. The NS variant from  
middle of June is among these functioning applications, the most  
recent builds fail, since they even don't allow to copy data to other  
Mac OS X applications.

My comment was mainly targeted to explain that you and NS Emacs don't  
need to take care of X11 since up-to-date X11 has means to make the  
pasteboard available for X clients. And this works fine.

Indeed*.

As per my other mail to this ticket, lisp/term/ns-win.el presently needs 
several updates to be able to fully handle some changes made to emacs 
default settings, I guess it was not really written to deal with 
settings other than the old defaults (i.e. the new settings would have 
broken it whether they were default or not).

I'll be taking a look at the weekend (n.b. the set of people with enough 
*step and x11 experience to fix it is probably larger than me, assuming 
I'm even in it).

Fair enough, I thought /you/ were unsure "(or..."


* Xquartz' configuration options in the area are something for emacs 
devs looking at bug reports to be aware of though - different mac users 
could easily have different sync behaviours configured which will cause 
different symptoms (I'm also thinking of effects on x11 emacs running 
under Xquartz).

Update: Taking a bit longer than I expected, mostly thanks to debian's 
gnustep packages having some known bugs on amd64 that _I_ didn't know 
about, could have saved myself a _lot_ of time just latest svn gnustep 
in the first place, gah.

One work-in-progess note: Turns out that first patch wasn't quite 
correct either, modern GNUstep's "gpbs" pasteboard daemon actually 
supports a conventional [1] mapping to X11 selections, as follows, 
visible in [2]

x11 side    ns side
CLIPBOARD   General Pasteboard
PRIMARY     "Selection" named pasteboard
SECONDARY   "Secondary" named pasteboard

(Wonder if the Xquartz guys are aware of that...)

I think it is quite obviously desirable that ns emacs adopt that scheme.

[1] At one stage gnustep did use a different scheme, there is still a 
backward compat defaults setting that flips them around 
("GSOldClipboard"), but the default is now the above, thankfully.

Updated patch that at least does this.  There are be
remaining issues, but it should work a bit better on macosx as well.

Great work, David! It works well in both directions! I'll start  
working with it tomorrow (it's now after midnight here).

Well, thanks, though I confess it is now mostly-working because of a 
reimplementation Chong Yidong did of select-active-regions, and Jan 
Djärv's adjustment to term/ns-win.el in the patch.

Hi Jan, you seem to have checked in the earlier GNUStep-incompatible NS 
pasteboard names, would you please switch in nsselect.m (line 542):

void
nxatoms_of_nsselect (void)
{
  NXPrimaryPboard = @"Selection";
  NXSecondaryPboard = @"Secondary";
}

As per the later version of my changes?

That way all of clipboard/primary/secondary work on gnustep/x11
