jedi-vim - awesome Python autocompletion with VIM
jedi-vim 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.
If you want to report issues, just use the github issue tracker. In case of questions about the software, please use stackoverflow and tag your question with jedi-vim.
We love Pull Requests! Read the instructions in CONTRIBUTING.md.
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 https://github.com/davidhalter/jedi-vim.git
On Arch Linux, you can also install jedi-vim from official repositories: 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, compiled with +conceal (which is not the case on some platforms, including OS X). If your VIM does not meet these requirements, the parameter recommendation list may not appear when you type an open bracket after a function name. Please read the documentation for details.
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", "bottom" or "winwidth". 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
Jedi displays function call signatures in insert mode in real-time, highlighting the current argument. The call signatures can be displayed as a pop-up in the buffer (set to 1, the default), which has the advantage of being easier to refer to, or in Vim's command line aligned with the function call (set to 2), which can improve the integrity of Vim's undo history.
let g:jedi#show_call_signatures = "1"
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"
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.

The tests are automatically run with travis.
