Jedi - an awesome autocompletion library for Python

Release v0.9.0. (Installation)

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.

Additionaly, Jedi suports two different goto functions and has support for renaming as well as Pydoc support and some other IDE features.

Jedi uses a very simple API to connect with IDE’s. There’s a reference implementation as a VIM-Plugin, which uses Jedi’s autocompletion. I encourage you to use Jedi in your IDEs. It’s really easy. If there are any problems (also with licensing), just contact me.

To give you a simple example how you can use the Jedi library, here is an example for the autocompletion feature:

>>> import jedi
>>> source = '''
... import datetime
... datetime.da'''
>>> script = jedi.Script(source, 3, len('datetime.da'), '')
>>> script
<Script: ''>
>>> completions = script.completions()
>>> completions                                         
[<Completion: date>, <Completion: datetime>, ...]
>>> print(completions[0].complete)
>>> print(completions[0].name)

As you see Jedi is pretty simple and allows you to concentrate on writing a good text editor, while still having very good IDE features for Python.

Autocompletion can look like this (e.g. VIM plugin):
