awmtt

awmtt (AwesomeWM Testing Tool) is a bash script that helps you test your Awesome configuration files.
It requires Xephyr, an Xorg-Application which can spawn a nested instance of xorg-server, allowing you to open multiple instances of Desktop Environments or Window Mangers like AwesomeWM.

Installation

ArchLinux users can find awmtt in the AUR.

Example Debian/Ubuntu manual installation:

sudo apt-get install xserver-xephyr
sudo wget -O /usr/bin/awmtt https://raw.githubusercontent.com/mikar/awmtt/master/awmtt.sh
sudo chmod a+x /usr/bin/awmtt

Here's an example of what it looks like:

Xephyr Usage

Have a look at http://awesome.naquadah.org/wiki/Using_Xephyr and its documentation to learn more about how to use it. For instance, you can press Control-Mod3-Shift to have Xephyr grab focus while inside the window so that you can't accidentally leave it. To let go, press Control-(Right-)Shift.
