bug#12750: Highlighting text no longer works

[Bruce Korb]

For many years, I have selected text and then pasted it where I wanted.
There is a new feature in emacs:  selected text is no longer in the
pasteable buffer.  I must move my hand from the mouse to the keyboard
to copy the text and then back to the mouse to paste it.  This is a bug.
Pending a fix in the next emacs release, how do I work around this problem?
Thank you!

$ rpm -q -a|grep -i emacs

Some experimentation has allowed me to characterize the issue better.
Double click a word and paste the word works fine.  The habit that
is broken is:

1. left click the end of some text
2. right click the start of some text
3. alt-shift-5 ctl-y (query replace followed by paste)
   Expected result: the text I just selected would be in the query-replace buffer
   Actual result:  the previous paste buffer gets inserted

Still a nuisance.

Actually, it's a feature: it was deemed a Good Thing to behave like
the other GUI applications.

See this entry in NEWS (what you want, if you still do, is at the
end):

  ** Selection changes.

  The default handling of clipboard and primary selections has been
  changed to conform with modern X applications.  In short, most
  commands for killing and yanking text now use the clipboard, while
  mouse commands use the primary selection.

  In the following, we provide a list of these changes, followed by a
  list of steps to get the old behavior back if you prefer that.

  *** `select-active-regions' now defaults to t.
  Merely selecting text (e.g. with drag-mouse-1) no longer puts it in
  the kill ring.  The selected text is put in the primary selection, if
  the system possesses a separate primary selection facility (e.g. X).

  **** `select-active-regions' also accepts a new value, `only'.
  This means to only set the primary selection for temporarily active
  regions (usually made by mouse-dragging or shift-selection);
  "ordinary" active regions, such as those made with C-SPC followed by
  point motion, do not alter the primary selection.

  **** `mouse-drag-copy-region' now defaults to nil.

  *** mouse-2 is now bound to `mouse-yank-primary'.
  This pastes from the primary selection, ignoring the kill-ring.
  Previously, mouse-2 was bound to `mouse-yank-at-click'.

  *** `x-select-enable-clipboard' now defaults to t on all platforms.

  *** `x-select-enable-primary' now defaults to nil.
  Thus, commands that kill text or copy it to the kill-ring (such as
  M-w, C-w, and C-k) also use the clipboard---not the primary selection.

  **** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now
  exactly equivalent to M-w, C-w, and C-y respectively.

  **** Note that on MS-Windows, `x-select-enable-clipboard' was already
  non-nil by default, as Windows does not support the primary selection
  between applications.

  *** To return to the previous behavior, do the following:

  **** Change `select-active-regions' to nil.
  **** Change `mouse-drag-copy-region' to t.
  **** Change `x-select-enable-primary' to t (on X only).
  **** Change `x-select-enable-clipboard' to nil.
  **** Bind `mouse-yank-at-click' to mouse-2.

Hi Eli,

Thank you.

It is quite inconvenient to switch stuff like this without more readily
apparent announcements.  Folks like me do not ever deliberately
update things, so we don't go reading "NEWS" of the 100+ things
that get updated automatically.

Sounds like the mouse ought to be using the clipboard to me.
Using separate mechanisms is clumsy.  This may explain why
I have so much difficulty pasting stuff into a Chrome buffer.
I think they must have it confused and wrong, too.
Seems to work okay in Firefox.  For Chrome, I often must go figure out
where in heck the "edit"->"select" thingy is and go through that menu
operation in order to be able to paste my text.

The separation was not well considered.  (expletives elided.)

The "modern" approach is brain damaged, so, yes, I prefer it.

It is really helpful to have explicit instructions:

*** To return to the previous behavior, add the following to your .emacs file:
    (setq select-active-regions         nil)
    (setq mouse-drag-copy-region        't)
    (setq x-select-enable-primary       't)
    (setq x-select-enable-clipboard     nil)
    (global-set-key [mouse-2]          'mouse-yank-at-click)

I do need explicit instructions.  This didn't work.  I want to
highlight and paste
and highlight and yank.  Both and.  This isn't working.  Help, please?
 Thank you!!

Which is exactly the same.

Either I really fumble-fingered the stuff (very possible), or it isn't exactly
the same.  After changing "'t" to "t" I've found that it works.
Perhaps I should change it back to "'t" to see if, indeed, it causes
it to not work the way I need it to.  I don't know. I _do_ know
that with:

> (setq select-active-regions         nil)

> (setq x-select-enable-clipboard     nil)
> (global-set-key [mouse-2]          'mouse-yank-at-click)

all my pasting works the way it should.  I know this:

* I highlighted and pasted into this email (mouse-2)
  (I later cut and pasted-as-quotation)
* I highlighted and clicked button 2 and pasted in emacs
* I highlighted and yanked (Ctl-Y) in emacs

That's what I needed!

Thank you all.  Regards, Bruce

You can find out yourself: (eq t 't)

You have to be more specific than that.  With a .emacs file, your
previous recipe

> 1. left click the end of some text
> 2. right click the start of some text
> 3. alt-shift-5 ctl-y (query replace followed by paste)

does indeed yank the text into the minibuffer.

Hmm.  OK, I use this many ways.  Sometimes, I click button 2,  sometimes
I type Ctl-Y.  Either way, I am very habituated to the selected text
being pasted.
I want to avoid having to remember Ctl-W/Ctl-C *ESPECIALLY* because I
don't even have Cmd-C working on my Mac.  I have to use the pull down menu
to access "edit->copy".  That becomes especially interesting when my
mouse crosses other emacs windows because if the mouse touches one
of them, then the selected text is no longer current and "edit->copy" grabs
a different block of text.

So, here's what I want:  I want the selected text to be inserted into all
buffers that relate to pasting of any sort.  If Mouse-2 and Ctl-Y refer to
different buffers, then both buffers should have the selected text.
How do I do this?

Thank you so much!!  Regards, Bruce
