by

Here’s a function that will change a pair of vertical windows to a pair of horizontal windows: (defun 2-windows-vertical-to-horizontal () (let ((buffers (mapcar ‘window-buffer (window-list)))) (when (= 2 (length buffers)) (delete-other-windows) (set-window-buffer (split-window-horizontally) (cadr buffers))))) To do this automatically on startup, add this function to emacs-startup-hook: (add-hook ’emacs-startup-hook ‘2-windows-vertical-to-horizontal)

These blocks are added by the customize interface, as Noufal pointed out. You can move them to a separate file, though, if you like. Just add this to your ~/.emacs.d/init.el: (setq custom-file “~/.emacs.d/custom.el”) (load custom-file) or, if you’re still using an old-fashioned ~/.emacs file: (setq custom-file “~/.custom.el”) (load custom-file) A slightly more complex snippet that … Read more
