it's minimal and dynamic

dminiwm is a very minimal and lightweight dynamic tiling window manager.

I will try to stay under 1000 SLOC.

Currently under 930 lines with the config file included.


It allows the "normal" method of tiling window managers(with the new window as the master) or with the new window opened at the bottom or the top of the stack.

There's vertical tiling mode:

|        | W |
|        |___|
| Master |   |
|        |___|
|        |   |

Horizontal tiling mode:

|           |
|  Master   |
| W |   |   |

Grid tiling mode:

|      | W  |
|Master|    |
|      |    |

Fullscreen mode(which you'll know when you see it)

All accessible with keyboard shortcuts defined in the config.h file.

  • The window W at the top of the stack can be resized on a per desktop basis.
  • Changing a tiling mode or window size on one desktop doesn't affect the other desktops.

Recent Changes
