Name¶

xmonad - Tiling Window Manager

Description¶

xmonad is a minimalist tiling window manager for X, written in Haskell. Windows are managed using automatic layout algorithms, which can be dynamically reconfigured. At any time windows are arranged so as to maximize the use of screen real estate. All features of the window manager are accessible purely from the keyboard: a mouse is entirely optional. xmonad is configured in Haskell, and custom layout algorithms may be implemented by the user in config files. A principle of xmonad is predictability: the user should know in advance precisely the window arrangement that will result from any action.

By default, xmonad provides three layout algorithms: tall, wide and fullscreen. In tall or wide mode, windows are tiled and arranged to prevent overlap and maximize screen use. Sets of windows are grouped together on virtual screens, and each screen retains its own layout, which may be reconfigured dynamically. Multiple physical monitors are supported via Xinerama, allowing simultaneous display of a number of screens.

By utilizing the expressivity of a modern functional language with a rich static type system, xmonad provides a complete, featureful window manager in less than 1200 lines of code, with an emphasis on correctness and robustness. Internal properties of the window manager are checked using a combination of static guarantees provided by the type system, and type-based automated testing. A benefit of this is that the code is simple to understand, and easy to modify.

Usage¶

xmonad places each window into a “workspace”. Each workspace can have any number of windows, which you can cycle though with mod-j and mod-k. Windows are either displayed full screen, tiled horizontally, or tiled vertically. You can toggle the layout mode with mod-space, which will cycle through the available modes.

You can switch to workspace N with mod-N. For example, to switch to workspace 5, you would press mod-5. Similarly, you can move the current window to another workspace with mod-shift-N.

When running with multiple monitors (Xinerama), each screen has exactly 1 workspace visible. mod-{w,e,r} switch the focus between screens, while shift-mod-{w,e,r} move the current window to that screen. When xmonad starts, workspace 1 is on screen 1, workspace 2 is on screen 2, etc. When switching workspaces to one that is already visible, the current and visible workspaces are swapped.

Examples¶

To use xmonad as your window manager add to your ~/.xinitrc file:

Customization¶

xmonad is customized in your xmonad.hs, and then restarted with mod-q. You can choose where your configuration file lives by

1.

Setting XMONAD_DATA_DIR, XMONAD_CONFIG_DIR, and XMONAD_CACHE_DIR; xmonad.hs is then expected to be in XMONAD_CONFIG_DIR.

2.

Creating xmonad.hs in ~/.xmonad.

3.

Creating xmonad.hs in XDG_CONFIG_HOME. Note that, in this case, xmonad will use XDG_DATA_HOME and XDG_CACHE_HOME for its data and cache directory respectively.

You can find many extensions to the core feature set in the xmonad- contrib package, available through your package manager or from xmonad.org (https://xmonad.org).
