Jedi is an autocompletion tool for Python that can be used in IDEs/editors.
Jedi works. Jedi is fast. It understands all of the basic Python syntax
elements including many builtin functions.

It's very easy to create an editor plugin that uses Jedi. See
https://jedi.readthedocs.org/en/latest/docs/plugin-api.html for more
information.
Testing
=======
The test suite depends on ``tox`` and ``pytest``::
pip install tox pytest
To run the tests for all supported Python versions::
PIP_INSECURE=t tox
If you want to test only a specific Python version (e.g. Python 2.7), it's as
easy as ::
tox -e py27
The ``PIP_INSECURE=t`` env variable is only needed for the ``py25`` target.
Tests are also run automatically on `Travis CI
<https://travis-ci.org/davidhalter/jedi/>`_.

Most auto-completions just didn't work well. The only good solution was PyCharm.
But I like my good old VIM. Rope was never really intended to be an

It's more of a refactoring suite. So I decided to do my own version of a
