2windows.el

Convenient 2 window creation and reorientation system for GNU Emacs.

Dependencies

1. Install GNU Emacs.
2. Install ace-window in GNU Emacs.

Setup

1. Add the following to your emacs Initialization File:

   (setq 2windows-file "/path/to/2windows.el")
   (if (file-exists-p 2windows-file)
       (progn (load 2windows-file)
              (global-set-key (kbd "C-2") 'sgang-2windows)))

2. Optional: change the C-2 above to any key that you like.

Usage

Assuming that sgang-2windows is bound to C-2 we have the following:

1. If there is only 1 window, then pressing C-2 results in the creation of a new window on the right while the currently selected window stays selected on the left.
2. If there are 2 windows, then each time C-2 is pressed, the same 2 windows are maintained but they are reoriented while keeping the same window selected. Successive presses of C-2 make the selected window cyclically go through the following sequence of orientations: left -> top -> bottom -> right -> left.
3. If there are more than 2 windows, then upon pressing C-2 the user is asked to select 2 windows using numerical hints provided by ace-window. All other windows are deleted, and the 2 chosen windows are (re)oriented vertically, with the window that was chosen first being selected (focused) and positioned on the left. The 2 selected windows are allowed to be the same.
