cwm (sometimes referred to as calmwm) is a stacking window manager for X Window System available on OpenBSD (included in base system),[1] NetBSD, DragonFlyBSD and Linux distributions using pkgsrc, Gentoo Linux and some other Linux distributions.

The acronym cwm stands for Calm Window Manager.[2]

History

Development of cwm started from patches to evilwm by Marius Aamodt Eriksen, but the evilwm's codebase "did not accomodate [sic] well for the new features added".[3] Some of 9wm code was used for rewrite.[4] The last release by the original author came out in August 2005.

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

Currently cwm is distributed with OpenBSD since release 4.2, where it replaced wm2.[6] Some Linux ports also exist.[7][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 doesn't draw window decorations except for 1 pixel border around the windows.

cwm includes several menus:[10]

  • exec menu (application launcher)
  • window menu (searching windows of running applications)
  • ssh to menu (start a Secure Shell session)
  • exec wm menu (switch window manager)

All these menus are operated in search as you type manner.[10]

cwm allows raising, hiding switching and searching windows with no use of mouse, making it suitable to use as terminal emulator multiplexer.[12] Furthermore, it allows manipulating pointing device with keyboard.[2]

The additional key bindings and configuration options can be specified in configuration file ~/.cwmrc.

Reception

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

Though not reviewed separately, cwm is noted to be used mainly due to its status of one of the default window managers in OpenBSD,[13] though other reasons are sometimes cited, such as being out of the ordinary[14] or allowing nice interaction with GUI.[15] Though it often gets no explanation, several OpenBSD users prefer to use cwm under Linux, even if it requires modifying and supporting source code.[8][16] cwm is also praised for its flexibility, ability to interact in a non-disruptive way and in having no dependency on using a mouse.[12][17]
