# simpleswitcher
A popup window switcher roughly based on [superswitcher](http://code.google.com/p/superswitcher/), requiring only xlib and xft.
This version is based on the version from [Sean
Pringle](http://github.com/seanpringle/simpleswitcher). All credit for this great tool should to to him.
* Switcher centered on screen (or monitor for multi-head).
@ -16,10 +18,21 @@ A popup window switcher roughly based on [superswitcher](http://code.google.com/
* Runs in background or once-off.
Hackish support for the I3 window manager:
If compiled with I3 support, it should autodetect if I3 window manager is running.
For i3, run with -i3
Usage
-----
e.g.
bindsym $mod+Tab exec simpleswitcher -i3 -now -font "snap-10" -fg "#505050" -bg "#000000" -hlfg "#ffb964" -hlbg "#000000" -o 85
bindsym $mod+Tab exec simpleswitcher -now -font "snap-10" -fg "#505050" -bg "#000000" -hlfg "#ffb964" -hlbg "#000000" -o 85
Compilation
-----------
Type `make I3=` to disable compiling with i3 support.
If during compilation it complains about not finding i3/ipc.h either disable i3 support
or install the headers.
Type `make PREFIX=<path> install` to install in a different prefix.
