Awesome autocompletion library for python. It's fast and working.

Jedi - an awesome Python auto-completion

Jedi is an autocompletion tool for Python. It works. With and without syntax errors. Sometimes it sucks, but that's normal in dynamic languages. But it sucks less than other tools. It understands almost all of the basic Python syntax elements including many builtins.

Jedi suports two different goto functions and has support for renaming. Probably it will also have some support for refactoring in the future.

Jedi uses a very simple interface to connect with IDE's. As an reference, there is a VIM implementation, which uses Jedi's autocompletion. However, I encourage you to use Jedi in your IDEs. Start writing plugins! If there are problems with licensing, just contact me.

At the moment Jedi can be used as a VIM-Plugin. So, if you want to test Jedi for now, you'll have to use VIM. But there are new plugins emerging:

• Emacs-Plugin
• Sublime-Plugin Under construction
• wdb (web debugger)

Here are some pictures:

Completion for almost anything (Ctrl+Space).

Display of function/class bodies, docstrings.

Pydoc support (with highlighting, Shift+k).

There is also support for goto and renaming.

Get the latest version from github (master branch should always be kind of stable/working).

Docs are available at https://jedi.readthedocs.org/. Pull requests with documentation enhancements and/or fixes are awesome and most welcome.

Jedi uses semantic versioning starting with version 0.6.0.

Installation

See https://jedi.readthedocs.org/en/latest/docs/installation.html

Note: This just installs the Jedi library, not the editor plugins. For information about how to make it work with your editor, refer to the corresponding documentation.

A little history

The Star Wars Jedi are awesome. My Jedi software tries to imitate a little bit of the precognition the Jedi have. There is even an awesome scene of Monty Python Jedi's :-).

But actually the name hasn't so much to do with Star Wars. It's part of my second name.

After I explained Guido van Rossum, how some parts of my auto-completion work, he said (we drank a beer or two):

Oh, that worries me

When it's finished, I hope he'll like it :-)

I actually started Jedi, because there were no good solutions available for VIM. Most auto-completions just didn't work well. The only good solution was PyCharm. I just like my good old VIM. Rope was never really intended to be an auto-completion (and also I really hate project folders for my Python scripts). It's more of a refactoring suite. So I decided to do my own version of a completion, which would execute non-dangerous code. But I soon realized, that this wouldn't work. So I built an extremely recursive thing which understands many of Python's key features.

By the way, I really tried to program it as understandable as possible. But I think understanding it might need quite some time, because of its recursive nature.

API for IDEs

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.
