[galaxy-dev] Getting tool dirpath in a Python code file

Hi, I have a tool with a <code file="my_script.py"/> tag and in that code file I'm trying to get the tool dirpath where that script and the tool XML exist. I've tried: os.path.abspath(os.path.dirname(sys.argv[0])) os.path.abspath(os.path.dirname(__file__)) And both don't work as expected. Is there a galaxy class I could import which will have the tool directory path? regards, Leandro
