Subject: 23.0.60; windmove.el doesnt not always switch windows in ERC
Date: Mon, 23 Jun 2008 03:14:08 +0200

When I am in an ERC buffer which is "touching" the bottom of my emacs session
I can't switch to windows to the left or right. (ie the only window below it
is the mini-buffer and the input prompt is at the bottom. Screenshot:
http://people.cs.uct.ac.za/~smtkee002/windmoveproblem.jpg ). I have tested in
other modes and this problem does not happen. C-x o still works.

I can't reproduce the behavior you describe here.  Could you try to
edebug `windmove-find-other-window' to find out what happens?

Thanks in advance, martin.

Sorry, I apparently mangled the mail header.  Resending:

Hey,
I ran edebug-eval-expression on (windmove-left) and got
call-interactively: Symbol's value as variable is void: edebug-outside-windows

Hope this helps

Cheers,
  Keegan

Not really.  Please try the following.  In a one-window frame do

C-x 2 C-x o C-x 3

that is your frame should appear as follows:

 -----
|     |
|-----|
|  |  |
 -----

In the lower right window display the ERC buffer, in the lower left
window the buffer you want to move to.  Next display window-move.el in
the top window, move point to the definition of
`windmove-find-other-window' and type C-u C-M-x to "instrument that
function for debugging".

Finally, go to the ERC window, and call `window-left'.  edebug should
now redirect focus to the upper window and you can type SPACE to step
through `windmove-find-other-window'.  If possible, do the same for a
non-ERC buffer in the lower right window too to tell where executions
differ.

Thanks, martin

Hey,
 I don't have window-move.el, it's defined in windmove.el
 Also, when i was debugging i had the ERC buffer running in the bottom
left corner.

When I run debug on windmove-find-other-window it doesnt give me any
output, but does take me to line 468 in windmove.el. The line is
(let* ((actual-current-window (or window (selected-window))) in the
function windmove-find-other-window

If i do the debug on windmove-right, nothing happens

I may be doing something wrong because I have never debugged lisp code
before, so could be doing it totally wrong. I am a programmer though
in C++, haskell, python and java though, so I do understand the
concepts behind debugging lisp. I'll read the info pages on edebug
sometime so I can maybe investigate the problem as well.

More information was requested three years ago, but apparently wasn't
given, so I'm closing this bug report.  Please reopen if it's still
valid.
