Using the jedi autocompletion library for VIM.

branch: master

jedi-vim - awesome Python autocompletion with VIM

Travis-CI build status

jedi-vim is a is a VIM binding to the autocompletion library Jedi.

Here are some pictures:

Completion for almost anything (Ctrl+Space).

Display of function/class bodies, docstrings.

Documentation (Pydoc) support (with highlighting, Shift+k).

There is also support for goto and renaming.

Get the latest from github.


Documentation is available in your vim: :help jedi-vim. You can also look it up on github.

You can read the Jedi library documentation here.

The Jedi library understands most of Python's core features. From decorators to generators, there is broad support.

Apart from that, jedi-vim supports the following commands

  • Completion <C-Space>
  • Goto assignments <leader>g (typical goto function)
  • Goto definitions <leader>d (follow identifier as far as possible, includes imports and statements)
  • Show Documentation/Pydoc K (shows a popup with assignments)
  • Renaming <leader>r
  • Usages <leader>n (shows all the usages of a name)
  • Open module, e.g. :Pyimport os (opens the os module)


You might want to use pathogen or vundle to install jedi in VIM. Also you need a VIM version that was compiled with +python, which is typical for most distributions on Linux. The Python version compiled into VIM must be 2.6 or later (you can check this from within VIM using :python import sys; print sys.version )

The first thing you need after that is an up-to-date version of Jedi. You can either get it via pip install jedi or with git submodule update --init in your jedi-vim repository.

Example Installation Command using Pathogen:

cd ~/.vim/bundle/ && git clone --recursive

On Arch Linux, you can also install jedi-vim from AUR: vim-jedi.

Note that the python-mode VIM plugin seems to conflict with jedi-vim, therefore you should disable it before enabling jedi-vim.

To enjoy the full features of Jedi-Vim, you should have VIM >= 7.3. For older version of VIM, the parameter recommendation list maybe not appeared when you type open bracket after the function name.


Jedi is by default automatically initialized. If you don't want that I suggest you disable the auto-initialization in your .vimrc:

let g:jedi#auto_initialization = 0

There are also some VIM options (like completeopt and key defaults) which are automatically initialized, but you can change all of them:

let g:jedi#auto_vim_configuration = 0

If you are a person who likes to use VIM-buffers not tabs, you might want to put that in your .vimrc:

let g:jedi#use_tabs_not_buffers = 0

If you are a person who likes to use VIM-splits, you might want to put this in your .vimrc:

let g:jedi#use_splits_not_buffers = "left"

This options could be "left", "right", "top" or "bottom". It will decide the direction where the split open.

Jedi automatically starts the completion, if you type a dot, e.g. str., if you don't want this:

let g:jedi#popup_on_dot = 0

Jedi selects the first line of the completion menu: for a better typing-flow and usually saves one keypress.

let g:jedi#popup_select_first = 0

Here are a few more defaults for actions, read the docs (:help jedi-vim) to get more information. If you set them to "", they are not assigned.

let g:jedi#goto_assignments_command = "<leader>g"
let g:jedi#goto_definitions_command = "<leader>d"
let g:jedi#documentation_command = "K"
let g:jedi#usages_command = "<leader>n"
let g:jedi#completions_command = "<C-Space>"
let g:jedi#rename_command = "<leader>r"
let g:jedi#show_call_signatures = "1"

Finally, if you don't want completion, but all the other features, use:

let g:jedi#completions_enabled = 0


I don't want the docstring window to popup during completion

This depends on the completeopt option. Jedi initializes it in its ftplugin. Add the following line to your .vimrc to disable it:

autocmd FileType python setlocal completeopt-=preview

I want <Tab> to do autocompletion

Don't even think about changing the Jedi command to <Tab>, use supertab!

The completion is waaay too slow!

Completion of complex libraries (like Numpy) should only be slow the first time you complete it. After that, the results should be cached and very fast.

If it's still slow, in case you've installed the python-mode VIM plugin, disable it. It seems to conflict with jedi-vim. See issue #163.


jedi-vim is being tested with a combination of vspec and py.test.

The tests are in the test subdirectory, you can run them calling:


The tests are automatically run with travis.
