ediff next/previous difference & point

ediff next/previous difference & point

[Florian Kaufmann]

Hello

I'm just starting to use ediff. Its a great tool from what I have seen
so far. What I would like to to is too browse through the differences
after I started a session with 'ediff'. The help says I have to press
'n' and 'p' to go to the next / previous difference while point is in
this special window of ediff. However if I do that, point goes to one
of the compared buffers. Now if I press n again to jump to the next
difference, an n character is inserted in that buffer. So what have I
to do to browse through the difference just pressing single commands?

Greetings

Flo

For me a little frame opens. When I press ? this one vanishes and  
another one opens, explaining how to use ediff. Could be you need to  
input n or p or SPACE in either of these extra frames ...

Thats true for me to, but it works only one time. Then the point is in
the buffer with the differences. If I press now n a second time,
because I want to go to the second difference, a literal n is inserted.
I have to make this little ediff frame active again to be able to press
n again such that I come to the next difference. I find this
cumbersume. Id rather liked just to press a series of n's and p's to
browse through the differences.

Can it be that you have the wrong value set for
C-h v focus-follows-mouse RET
?

focus-follows-mouse is a variable defined in `frame.el'.
Its value is t

Documentation:
*Non-nil if window system changes focus when you move the mouse.
You should set this variable to tell Emacs how your window manager
handles focus, since there is no way in general for Emacs to find out
automatically.

This variable does not have any effect on MS-Windows.

You can customize this variable.

I think this doesn't solve the problem, I played around with this
variable. However I noticed that all works fine if the ediff frame is
really small. If I make it larger by pressing ?, after a couple of n's
and p's, the problem as described at the beginning of the thread
starts. This just as info, I can live with that state.

Can it be that you enter any of the two buffers to be compared? To  
copy some text ...

I think that is the case for Florian.

A related note for ediff:

I use the following setting in my .emacs:
(setq ediff-window-setup-function 'ediff-setup-windows-plain)

Now I don't get an extra frame for the ediff control panel. And it is
possible to switch to a buffer or the control panel via C-x C-o

I don't think this an advantage: with more than two windows, C-x o
[sic!] gets messy.  Having two frames and being able to switch between
them with C-x 5 o seems much more convenient.

Me too.

Why do you need this?

I find it VERY inconvenient.  This separate frame often gets lost. C-x
5 o
gets messy when you have extra frames; and this is a different
interface
compared to the console.

Uh what?  Are you sure that you have set focus-follows-mouse to the
right setting?  Or have you something like "raise-on-focus" set as a
window manager preference?

> C-x 5 o gets messy when you have extra frames;

What are "extra frames"?

> and this is a different interface compared to the console.

????  What is the point here?

Well, there are several environments I have to use.  Generally my
employer wants me to use MS Windows.  I have set a mode similar to
focus-follows-mouse in the Registry (and the variable inside emacs
too), but there are often other Windows events which have strange
effects.  I do not remember very well all the trouble which a separate
Ediff-Control-Panel frame caused to me, because setting
ediff-setup-windows-plain is one of the first customizations I
normally do.

>> C-x 5 o gets messy when you have extra frames;

> What are "extra frames"?

Quite often I need a separate frame, e.g. for a buffer in which I
could take my notes as I browse the differences.  It is convenient to
have it in a separate frame, so that I have the 3 ediff windows and 2
frames; I can navigate windows with "C-x o" (not very often, in fact),
and I can switch frames with "C-x 5 o" (quite frequently).  If the
Ediff Control Panel is in a separate frame, is meddles in an unwanted
way in the switching process.

When I start "emacs -nw" (as it is usual when I use console, e.g. in a
remote terminal), I have no frames anyway.

When I ride a bicycle, I don't have windscreen wipers, anyway.  But
that does not preclude me from using them when I am in a car.

To be honest, I don't use C-x o to switch to the other buffer, I have
bound F4 to do the switching. So I hit F4 several times until I have
selected the correct buffer.

And I use only one emacs frame with some special window configurations
(e.g. for gnus).
That setup works very well for me, but I can imagine that you have
different working habits.
