pop-to-buffer / switch-to-buffer-other-window

pop-to-buffer / switch-to-buffer-other-window

[Jean-Christophe Helary]

When I have just one window open, switch-to-buffer-other-window sometimes splits vertically and sometimes horizontally to display the other window.

In the documentation, there are plenty of references to "some window" but little if anything about how that window is chosen/created.

What is the rationale behind this lack of consistency ? Or is there some consistency, for ex based on the mode ?

Please see "Splitting Windows" in the ELisp manual, it describes how Emacs decides whether to split vertically or horizontally.

Do you mean this:

split-window &optional window size *side* pixelwise

It just says that the side argument affects the function, not what in pop-to-buffer causes that argument to be set. And I don't find any reference to splitting in pop-to-buffer for that matter.

Thrn I guess you should read "Choosing Window Options".  My point is that this is described in the manual.

Interesting. There is this 'split-window-sensibly function that tries to adapt to the display.

But the impression I get from reading the manuals is that there is a general preference for vertical splitting.

The issue with is that with rectangular displays and considering that most documents have a given reasonable width, choosing to split the main window vertically is rarely the best solution in terms of screen space use.

I'll try to be more careful and see in which case I see unpleasant behavior and see if I can do this about it.

Thank you.

It's just the matter of tuning the two thresholds mentioned there.

I can see that.

My ideal ? behavior would be to keep the main window and send anything informative on the side but anything I need to action in the front window.

So it's not really thresholds tweaking... I guess the default settings are reasonable so I'll see what I have in my copy-pasted config that interferes...
