This project includes a script that uses reflection to extract blender's python API from a running instance of blender and store it in .py files usable by the pycharm IDE to aid in code completion. This source code is derived from pydev-blender.zip at http://airplanes3d.net/pydev-000_e.xml First: generate a fresh set of skeletons using ./refresh_python_api (which simply invokes python_api/pypredef_gen.py inside blender) Then you can add the python_api/pypredef directory to pycharm's interpreter using the screenshot pycharm-3.4-screenshot.png and the instructions at http://stackoverflow.com/a/24206781/995935 If you do not want to add the blender API stubs to all your pycharm projects you can simply add the python_api/pypredef directory to your Project Structure. https://www.blender.org/download/ https://www.jetbrains.com/pycharm/
