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.

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 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 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.

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

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 splits not tabs, you might want to put that in your .vimrc:

let g:jedi#use_splits_not_buffers = 1

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

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

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

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:

py.test

The tests are automatically run with travis.
