Tab completion in pyROOT in an IDE environment

Hi,

Autocompletion for PyROOT in Jupyter is provided by this module:

root-project/root/blob/master/bindings/jupyroot/python/JupyROOT/helpers/cppcompleter.py

Please note that the case of an IDE is different, since the code is not running as it is in a Jupyter notebook. In this regard, PyROOT is special, because it does everything lazily: no Python equivalent for any C++ class exists a priori, all the lookups and done dynamically at execution time via ROOT and its C++ meta classes. This makes it challenging to provide autocompletion in IDEs for PyROOT.
