Opensnap brings the Aero Snap feature to Openbox.

If you didn't find any bugs, feel free to drop me a message at opensnap{ät]dumbinter[döt}net anyways. I'm happy for any feedback. But please report bugs on github if possible.

The goal was to make it work with every EWMH compliant window manager.

You'll need wmctrl.

On most debian systems you should be able to install it by:

sudo apt-get install wmctrl

If you want to build it make sure you have these as well:

sudo apt-get install build-essential libx11-dev libgtk-3-dev

If you want to install opensnap from source first make sure you have git installed. (Or fetch a zip file: https://github.com/lawl/opensnap/archive/master.zip)

Fetch via git:

git clone https://github.com/lawl/opensnap.git

Fetch via zip:

wget https://github.com/lawl/opensnap/archive/master.zip
unzip master.zip

Make sure you have all prerequisits:

sudo apt-get install build-essential libx11-dev libgtk-3-dev wmctrl

And finally build and install it:

cd opensnap*
make
mkdir -p ~/.config/opensnap
cp sample_configs/* ~/.config/opensnap/

And now start opensnap by

bin/opensnap --daemon

This should tell you all you need to know:

opensnap --help

Copy the sample configs to ~/.config/opensnap/.

As of now opensnap does not support unsnapping (see #4). You can find a workaround here: lawl#4 (comment)

Do note however that this does not perfect unsnapping. I.e. your cursor possition and the window you are dragging might get displaced a bit on unsnapping. But it does work well enough for daily use.
