Jedi is a static analysis tool for Python that is typically used in IDEs/editors plugins. Jedi has a focus on autocompletion and goto functionality. Other features include refactoring, code search and finding references.

Jedi has a simple API to work with. There is a reference implementation as a VIM-Plugin _. Autocompletion in your REPL is also possible, IPython uses it natively and for the CPython REPL you can install it. Jedi is well tested and bugs should be rare.

Jedi can currently be used with the following editors/projects:

• Vim (jedi-vim_, YouCompleteMe_, deoplete-jedi_, completor.vim_)
• Visual Studio Code_ (via Python Extension _)
• Emacs (Jedi.el_, company-mode_, elpy_, anaconda-mode_, ycmd_)
• Sublime Text (SublimeJEDI_ [ST2 + ST3], anaconda_ [only ST3])
• TextMate_ (Not sure if it's actually working)
• Kate_ version 4.13+ supports it natively, you have to enable it, though. [`see

`_]

• Atom_ (autocomplete-python-jedi_)
• GNOME Builder_ (with support for GObject Introspection)
• Gedit (gedi_)
• wdb_ - Web Debugger
• Eric IDE_
• IPython 6.0.0+ _
• xonsh shell _ has jedi extension _

and many more!

There are a few language servers that use Jedi:

• jedi-language-server _
• python-language-server _ (currently unmaintained)
• python-lsp-server _ (fork from python-language-server)
• anakin-language-server _

Here are some pictures taken from jedi-vim_:

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

Docs are available at https://jedi.readthedocs.org/en/latest/ _. Pull requests with enhancements and/or fixes are awesome and most welcome. Jedi uses semantic versioning _.

Issues & Questions ==================

You can file issues and questions in the issue tracker . Alternatively you can also ask on Stack Overflow _ with the label `python-jedi`.

Installation ============

Check out the docs _.

Features and Limitations ========================

Jedi's features are listed here: Features _.

You can run Jedi on Python 3.6+ but it should also understand code that is older than those versions. Additionally you should be able to use Virtualenvs _ very well.

Tips on how to use Jedi efficiently can be found here _.

API ---

You can find a comprehensive documentation for the API here _.

Autocompletion / Goto / Documentation -------------------------------------

There are the following commands:

• jedi.Script.goto
• jedi.Script.infer
• jedi.Script.help
• jedi.Script.complete
• jedi.Script.get_references
• jedi.Script.get_signatures
• jedi.Script.get_context

The returned objects are very powerful and are really all you might need.

Autocompletion in your REPL (IPython, etc.) -------------------------------------------

Jedi is a dependency of IPython. Autocompletion in IPython with Jedi is therefore possible without additional configuration.

Here is an example video _ how REPL completion can look like. For the `python shell you can enable tab completion in a REPL `_.

Static Analysis ---------------

For a lot of forms of static analysis, you can try to use `jedi.Script(...).get_names. It will return a list of names that you can then filter and work with. There is also a way to list the syntax errors in a file: jedi.Script.get_syntax_errors`.

Refactoring -----------

Jedi supports the following refactorings:

• jedi.Script.inline
• jedi.Script.rename
• jedi.Script.extract_function
• jedi.Script.extract_variable

Code Search -----------

There is support for module search with `jedi.Script.search, and project search for jedi.Project.search. The way to search is either by providing a name like foo or by using dotted syntax like foo.bar. Additionally you can provide the API type like class foo.bar.Bar. There are also the functions jedi.Script.complete_search and jedi.Project.complete_search`.

Development ===========

There's a pretty good and extensive development documentation _.

Testing =======

The test suite uses `pytest`::

pip install pytest

If you want to test only a specific Python version (e.g. Python 3.8), it is as easy as::

python3.8 -m pytest

For more detailed information visit the testing documentation _.
