Setting Emacs to Split Buffers Side-by-Side

Question

A lot of Emacs functions automatically split the screen. However, they all do so such that the windows are one on top of the other. Is there any way to make them split such

Answer 1

I use multiple frames (OSX windows) in emacs regularly for different projects. Here's how I setup a few frames initially split to a left and right window.

  (defun make-maximized-split-frame (name)
    (let (( f (make-frame (list (cons 'name  name))) ))
      (maximize-frame f)
      (split-window (frame-root-window f) nil t)
      ))

  (make-maximized-split-frame "DocRaptor")
  (make-maximized-split-frame "Gauges")
  (make-maximized-split-frame "Instrumental")
