cwm (Calm Window Manager)[1] is a stacking window manager for the X Window System. While it is primarily developed as a part of OpenBSD's base system,[2] portable versions are available on other Unix-like operating systems.

History

Development of cwm started from patches to evilwm by Marius Aamodt Eriksen.[3] To ease the implementation of new features, cwm was eventually rewritten using some code from 9wm.[4] The last release by the original author came out in August 2005.[3]

In April 2007, cwm was imported into OpenBSD source tree.[5] By January 2008, a substantial part of the original source code, including all of the 9wm code, was rewritten.[6]

cwm has been distributed with OpenBSD since version 4.2, where it replaced wm2.[7] A third-party Linux port also exists.[8]

Description

cwm is a stacking window manager oriented towards heavy keyboard usage,[9][10] small footprint and ease of use. While it lacks explicit virtual desktops functionality, it can be emulated by using the window groups mechanism.[11] cwm does not draw window decorations except for a 1-pixel border around windows.

cwm includes several menus:[10]

All these menus operate in a "search as you type" manner.[10]

cwm allows raising, hiding, switching between, and searching for windows using just the keyboard, making it suitable to use as terminal emulator multiplexer.[12] Furthermore, it allows manipulating pointing devices, such as mice, with the keyboard.[1]

Additional key bindings and configuration options can be specified in the configuration file ~/.cwmrc.

Reception

cwm is generally well received in software minimalist communities.[10]

cwm is noted to be used mainly due to its status as one of the default window managers in OpenBSD,[13] though other reasons are sometimes cited.[14][15] cwm is also praised for its flexibility, ease of use, and the fact that it can be used without a mouse.[12][16]
