In
Unix computing, Ion is a
tiling and
tabbing window manager for the
X Window System. It is designed such that it is possible to manage
windows using only a
keyboard, without needing a
mouse. It is the successor of
PWM and is written by the same author, Tuomo Valkonen. Since the first release of Ion in the summer 2000, similar alternative window management ideas have begun to show in other new window managers:
Larswm,
ratpoison,
StumpWM,
WMI, and
TrsWM. First versions of Ion were released under the
Artistic License, Ion2 and the development versions of Ion3 were released under the
GNU Lesser General Public License (LGPL). However, the first release candidate of Ion3 included a license change to a custom license based on the LGPL. Since version 2, Ion has been scriptable in the
Lua programming language.
