Hi, is it possible to have Emacs show only one modeline at the very
bottom of the screen, which shows information about the buffer in the
selected window? E.g. instead of this,
| [#]include <stdio.h> | (defun add (x y) (+ x y)\|
| int main(int argc, char \| ) |
| ** argv, char ** envp) { | (ad[d] 5 6) ;=> 11 |
-------------------------------------------------------
|-:-- hello.c Top (1, 0) |-:**- *scratch* Top (2, 2)|
-------------------------------------------------------
| |
-------------------------------------------------------
Can I have sth. like the following?
| [#]include <stdio.h> | (defun add (x y) (+ x y)\|
| int main(int argc, char \| ) |
| ** argv, char ** envp) { | (add 5 6) ;=> 11 |
-------------------------------------------------------
|-:-- hello.c Top (1, 0) (C/l Arev AC hl-p hl-s Abb|
-------------------------------------------------------
| |
-------------------------------------------------------
Cheers

One problem with this is distinguishing the border between two buffers
above/below each other. You might still want some kind of bar rendered there,
perhaps with a different content?

Not really. This would require a major redesign of the involved
components. If you have Emacs 24.4 you can try (better with Emacs -Q)
the proof of concept below (for fun only).
If you are really interested, you'd have to fill in two things:
(1) A mechanism that would allow this to work with multiple frames (that
is, things like mode-line-buffer and mode-line-window would have to
become frame parameters). This is fairly easy.
(2) A mechanism to implement keybindings in the mode-line buffer. This
should be easy too but is likely tedious. You would mostly have to
replace occurrences of
(with-selected-window (posn-window (event-start event))
with something like
(with-selected-window mode-line-really-selected-window
where mode-line-really-selected-window would refer to the window the
mode-line is currently talking about.

My response would be: why?
A mode line is mode-specific by design.
Sounds like this might be an XY problem.

What is the real problem you are trying to solve or the
real feature you are looking for? Can you describe it without
mentioning the mode line?
