The plugin code as well as the pyembroidery repository can be found within the Ink/Stitch organization on github. Additionaly you will find some other useful things like embroidery fonts.
Ink/Stitch is an Inkscape plugin. See their website to read a short introduction about how to write Inkscape plugins.
Ink/Stitch and pyembroidery are written in Python 2.
We cannot use Python 3 because inkex.py, the extension framework for Inkscape, is in Python 2 only.
