xmonad is a window manager for the X Window System . It is written in the functional programming language Haskell .

In March 2007, xmonad was introduced as a tiling- based window manager. It therefore organizes the displayed windows like tiles so that they do not overlap. In addition, the developers endeavored to create a graphical user interface in which users can work productively with the windows without using the mouse . Many Linux distributions ship xmonad directly through their package management systems and it is also available for FreeBSD , NetBSD , OpenBSD , and macOS .

properties

Originally, xmonad was based on dwm in terms of functionality and operation , for example in terms of the preset key assignment. However, it now includes features that are not available to dwm users. These are, for example, a layout that can be configured for each desktop environment , tile reflection, storage of the state, mirroring of the layout and Gnome support and status bars for each screen (X abstraction). It can be customized by editing an external configuration file that can be reloaded during operation.

The xinerama support from xmonad: tiling on three monitors at the same time (with Kinesis keyboard)

Extensions for the core system, such as the emulation of other window managers and unusual layout algorithms such as window division based on the Fibonacci spiral , have been implemented by the community and are available as a library .

In addition to the focus on doing without the mouse, the xmonad developers often use semi- formal methods and program derivation to increase reliability and reduce the number of source code lines . With version 0.7 this was reduced to less than 1200 and window manager settings such as the behavior of the focus are now controlled by the Haskell QuickCheck library . This focus makes xmonad unusual in several ways. It is also the first window manager that the zipper - data structure uses to automatically organize the focus.

xmonad makes use of Haskell features and tools such as QuickCheck, GHC extensions such as pattern guards , monads , monad transformers , zippers, and the Cabal package system, as well as Haskell bindings to Xlib and xft fonts. There are plans to rebind to XCB when the Haskell bindings are released. Its core has been checked for security in terms of pattern matching , which further contributes to reliability.

influence

Xmonad's innovations have also influenced other tiling-based window managers. Dwm took over “urgency hooks” from xmonad and has been supporting Xinerama (for multi-head systems) since release 4.8. There is also a patch inspired by xmonad , which adds two layouts to dwm, which arrange windows according to the Fibonacci sequence .
