Window remembering last used buffer and i-search

Window remembering last used buffer and i-search

[Lars Brange]

Hello,

Is there any function or extension to emacs 21.2.1 that let each window
remember its last used buffer and last i-search string? I often have the
same buffer open in two windows and then switch to another buffer in one
of the windows. I then want to switch back to the first buffer again in
that window (ie I have the same buffer in the two windows again). The
problem is that emacs suggest the second last used buffer for *all*
emacs windows, not the one I'm currently using. This means I have to
enter the buffer name again; I don't want to do that...

Also, I would like emacs to remember the last i-search string for each
window or buffer. Now I have a global i-search string for all
windows/buffers.

Thanks in advance,

Lars Brange

Maybe you can save the window configuration to achieve this.  I think
winner-mode can do this.  If not, then
window-configuration-to-register might help.

You could try `M-x winner-mode RET'. When you have winner-mode thus
activated, Emacs makes window-configurations "undoable". Use 
`C-x <left>' to switch to the previous configuration. ("redo" is on
`C-x <right>'. It does not preserve point, though.

To get this buffer local, you could eval

(make-local-variable 'search-ring)

in your buffer (use a hook etc. as appropriate).

In order to get this window local, you'd have to hack Emacs' C core,
I'm afraid.

Or in your ~/.emacs file (i.e. globally):


(make-variable-buffer-local 'search-ring)

Thanks for the help everyone. The winner-mode was not exactly want I wanted
but it can work. make-variable-buffer-local works fine.

Hi,

when yu call i-search using C-s simply hit C-s again, and it will search
for the last used search string.

Cheers

I know. What I want to do is that I want to have different i-search strings for
each buffer. Let's say I start a search for "main" in one buffer and then
switch to another buffer and search for "sub". When I switch back to the first
buffer and hit C-s twice I want it to use "main", not "sub".
