1. Introduction *jedi-vim-introduction*
Jedi-vim is a Vim binding to the awesome Python autocompletion library
`jedi`. Among jedi's (and, therefore, jedi-vim's) features are:
- Completion for a wide array of Python features (see |jedi-vim-support|)
- Robust in dealing with syntax errors and wrong indentation
- Parses complex module/function/class structures
- Infers function arguments from Sphinx/Epydoc strings
- Doesn't execute Python code
- Supports Virtualenv
- Supports Python 2.7 and 3.4+
By leveraging this library, jedi-vim adds the following capabilities to Vim:
- Displaying function/class bodies
- "Go to definition" command
- Displaying docstrings
- Renaming and refactoring
- Looking up related names
==============================================================================
2. Installation *jedi-vim-installation*
------------------------------------------------------------------------------
2.0. Requirements *jedi-vim-installation-requirements*
First of all, jedi-vim requires Vim to be compiled with the `+python` option.
It is best if you have VIM >= 7.3, compiled with the `+conceal` option. With
older versions, you will probably not see the parameter recommendation list
for functions after typing the open bracket. Some platforms (including OS X
releases) do not ship a VIM with `+conceal`. You can check if your VIM has the
feature with >
:ver
and look for "`+conceal`" (as opposed to "`-conceal`") or >
:echo has('conceal')
which will report 0 (not included) or 1 (included). If your VIM lacks this
feature and you would like function parameter completion, you will need to
build your own VIM, or use a package for your operating system that has this
feature (such as MacVim on OS X, which also contains a console binary).
------------------------------------------------------------------------------
2.1. Installing manually *jedi-vim-installation-manually*
1. If you want to install jedi as a submodule instead, issue this command: >
git clone --recursive http://github.com/davidhalter/jedi-vim
2. Put the plugin files into their respective folders in your vim runtime
directory (usually ~/.vim). Be sure to pay attention to the directory
structure!
3. Update the Vim help tags with >
:helptags <path/to/vimruntime>/doc
------------------------------------------------------------------------------
2.2. Installing using Pathogen *jedi-vim-installation-pathogen*
Pathogen simplifies installation considerably.
1.a Clone the git repository into your bundles directory: >
git clone http://github.com/davidhalter/jedi-vim path/to/bundles/jedi-vim
1b. Again, if you want to install jedi as a submodule, use this command
instead: >
git clone --recursive http://github.com/davidhalter/jedi-vim
------------------------------------------------------------------------------
2.3. Installing using Vundle *jedi-vim-installation-vundle*
1. Vundle automatically downloads subrepositories as git submodules, so you
will automatically get the jedi library with the jedi-vim plugin. Add the
following to the Bundles section in your .vimrc file: >
Plugin 'davidhalter/jedi-vim'
2. Issue the following command in Vim: >
:PluginInstall
Help tags are generated automatically, so you should be good to go.
------------------------------------------------------------------------------
2.4. Installing from Repositories *jedi-vim-installation-repos*
Some Linux distributions have jedi-vim packages in their official
repositories. On Arch Linux, install vim-jedi. On Debian (8+) or Ubuntu
(14.04+) install vim-python-jedi.
==============================================================================
3. Supported Python features *jedi-vim-support*
The Jedi library does all the hard work behind the scenes. It understands most
Python features, among them:
- Builtins
- Multiple `return`s or `yield`s
- Tuple assignments/array indexing/dictionary indexing
- `with`-statement/exception handling
- `*args` and `**kwargs`
- Decorators, lambdas, closures
- Generators, iterators
- Some descriptors: `property`/`staticmethod`/`classmethod`
- Some magic methods: `__call__`, `__iter__`, `__next__`, `__get__`,
`__getitem__`, `__init__`
- `list.append()`, `set.add()`, `list.extend()`, etc.
- (Nested) list comprehensions and ternary expressions
- Relative `import`s
- `getattr()`/`__getattr__`/`__getattribute__`
- Function annotations (py3k feature, are being ignored at the moment, but are
parsed)
- Class decorators (py3k feature, are being ignored at the moment, but are
parsed)
- Simple/usual `sys.path` modifications
- `isinstance` checks for `if`/`while`/`assert` case, that doesn't work with
Jedi
- Stubs
- And more...
Note: This list is not necessarily up to date. For a complete list of
features, please refer to the Jedi documentation at
http://jedi.readthedocs.io.
==============================================================================
4. Usage *jedi-vim-usage*
With the default settings, autocompletion can be triggered by typing
<Ctrl-Space>. The first entry will automatically be selected, so you can press
<Return> to insert it into your code or keep typing and narrow down your
completion options. The usual <C-X><C-O> and <C-P>/<C-N> keybindings work as
well. Autocompletion is also triggered by typing a period in insert mode.
Since periods rarely occur in Python code outside of method/import lookups,
this is handy to have (but can be disabled).
When it encounters a new module, jedi might take a few seconds to parse that
module's contents. Afterwards, the contents are cached and completion will be
almost instantaneous.
==============================================================================
5. Key Bindings *jedi-vim-keybindings*
All keybindings can be mapped by setting the appropriate global option. For
example, to set the keybinding for starting omnicompletion to <C-N> instead of
<Ctrl-Space>, add the following setting to your .vimrc file: >
let g:jedi#completions_command = "<C-N>"
Note: If you have |g:jedi#auto_initialization| set to 0, you have to create
a mapping yourself by calling a function: >
" Using <C-N> for omnicompletion
inoremap <silent> <buffer> <C-N> <c-x><c-o>
" Use <localleader>r (by default <\-r>) for renaming
nnoremap <silent> <buffer> <localleader>r :call jedi#rename()<cr>
" etc.
Note: You can set commands to '', which means that they are empty and not
assigned. It's an easy way to "disable" functionality of jedi-vim.
------------------------------------------------------------------------------
5.1. `g:jedi#completions_command` *g:jedi#completions_command*
Function: n/a; see above
Default: <Ctrl-Space> Start completion
Performs autocompletion (or omnicompletion, to be precise).
Note: If you want to use <Tab> for completion, please install Supertab:
https://github.com/ervandew/supertab.
------------------------------------------------------------------------------
5.2. `g:jedi#goto_command` *g:jedi#goto_command*
Function: `jedi#goto()`
Default: <leader>d Go to definition (or assignment)
This function first tries |jedi#goto_definitions|, and falls back to
|jedi#goto_assignments| for builtin modules. It produces an error if nothing
could be found.
NOTE: this implementation is subject to change.
Ref: https://github.com/davidhalter/jedi/issues/570
This command tries to find the original definition of the function/class under
the cursor. Just like the `jedi#goto_assignments()` function, it does not work
if the definition isn't in a Python source file.
The difference between `jedi#goto_assignments()` and `jedi#goto_definitions()`
is that the latter performs recursive lookups. Take, for example, the
following module structure: >
# file1.py:
from file2 import foo
# file2.py:
from file3 import bar as foo
# file3.py
def bar():
pass
The `jedi#goto_assignments()` function will take you to the >
from file2 import foo
statement in file1.py, while the `jedi#goto_definitions()` function will take
you all the way to the >
def bar():
line in file3.py.
------------------------------------------------------------------------------
5.3. `g:jedi#goto_assignments_command` *g:jedi#goto_assignments_command*
Function: `jedi#goto_assignments()`
Default: <leader>g Go to assignment
This function finds the first definition of the function/class under the
cursor. It produces an error if the definition is not in a Python file.
------------------------------------------------------------------------------
5.4. `g:jedi#goto_stubs_command` *g:jedi#goto_stubs_command*
Function: `jedi#goto_stubs()`
Default: <leader>s Go to stub
Finds the stub of the function/class under the cursor.
------------------------------------------------------------------------------
5.5. `g:jedi#documentation_command` *g:jedi#documentation_command*
Function: `jedi#show_documentation()`
Default: <K> Show pydoc documentation
This shows the pydoc documentation for the item currently under the cursor.
The documentation is opened in a horizontally split buffer. The height of this
buffer is controlled by `g:jedi#max_doc_height` (set by default to 30).
------------------------------------------------------------------------------
5.6. `g:jedi#rename_command` *g:jedi#rename_command*
Function: `jedi#rename()`
Default: <leader>r Rename variables
Jedi-vim deletes the word currently under the cursor and puts Vim in insert
mode, where the user is expected to enter the new variable name. Upon leaving
insert mode, jedi-vim then renames all occurrences of the old variable name
with the new one. The number of performed renames is displayed in the command
line.
------------------------------------------------------------------------------
5.7. `g:jedi#rename_command_keep_name` *g:jedi#rename_command_keep_name*
Function: `jedi#rename()`
Default: <leader>R Rename variables
(This key mapping does not delete the word under the cursor)
Jedi-vim keeps the word currently under the cursor, moves the cursor to the end
of the word, and puts Vim in insert mode, where the user is expected to enter
the new variable name. Upon leaving insert mode, Jedi-vim then renames all
occurrences of the old variable name with the new one. The number of performed
renames is displayed in the command line.
------------------------------------------------------------------------------
5.8. `g:jedi#usages_command` *g:jedi#usages_command*
Function: `jedi#usages()`
Default: <leader>n Show usages of a name.
The quickfix window is populated with a list of all names which point to the
definition of the name under the cursor.
------------------------------------------------------------------------------
5.9. Open module by name *:Pyimport*
Function: `jedi#py_import(args)`
Default: :Pyimport e.g. `:Pyimport os` shows os.py in VIM.
Simulate an import and open that module in VIM.
==============================================================================
6. Configuration *jedi-vim-configuration*
Note: You currently have to set these options in your .vimrc. Setting them in
an ftplugin (e.g. ~/.vim/ftplugin/python/jedi-vim-settings.vim) will not work
because jedi-vim is not set up as an filetype plugin, but as a "regular"
plugin.
------------------------------------------------------------------------------
6.1. `g:jedi#auto_initialization` *g:jedi#auto_initialization*
Upon initialization, jedi-vim performs the following steps:
1. Set the current buffers 'omnifunc' to its own completion function
`jedi#completions`
2. Create mappings to commands specified in |jedi-vim-keybindings|
3. Call `jedi#configure_call_signatures()` if
`g:jedi#show_call_signatures` is set
You can disable the default initialization routine by setting this option to
0. Beware that you have to perform the above steps yourself, though.
Options: 0 or 1
Default: 1 (Perform automatic initialization)
------------------------------------------------------------------------------
6.2. `g:jedi#auto_vim_configuration` *g:jedi#auto_vim_configuration*
Jedi-vim sets 'completeopt' to `menuone,longest` and `popup` (for Vim version
numbers higher than 8.1.1882) respectively `preview` by default, if
'completeopt' is not changed from Vim's default.
It also remaps <Ctrl-C> to <Esc> in insert mode.
If you want to keep your own configuration, disable this setting.
Options: 0 or 1
Default: 1 (Set 'completeopt' and mapping as described above)
------------------------------------------------------------------------------
6.3. `g:jedi#popup_on_dot` *g:jedi#popup_on_dot*
Jedi-vim automatically starts completion upon typing a period in insert mode.
However, when working with large modules, this can slow down your typing flow
since you have to wait for jedi to parse the module and show the completion
menu. By disabling this setting, completion is only started when you manually
press the completion key.
You need to also have `g:jedi#completions_enabled` enabled for this.
Options: 0 or 1
Default: 1 (Start completion on typing a period)
------------------------------------------------------------------------------
6.4. `g:jedi#popup_select_first` *g:jedi#popup_select_first*
Upon starting completion, jedi-vim can automatically select the first entry
that pops up (without actually inserting it).
This leads to a better typing flow: As you type more characters, the entries
in the completion menu are narrowed down. If they are narrowed down enough,
you can just press <Return> to insert the first match.
Options: 0 or 1
Default: 1 (Automatically select first completion entry)
------------------------------------------------------------------------------
6.5. `g:jedi#auto_close_doc` *g:jedi#auto_close_doc*
When doing completion and jedi-vim shows the docstring of the currently selected
item in a preview (not a popup) window, this window is being closed after
insertion of a completion item.
Set this to 0 to leave the preview window open even after leaving insert mode.
This could be useful if you want to browse longer docstrings.
This setting is ignored if a popup instead of a preview window is used.
Options: 0 or 1
Default: 1 (Automatically close preview window upon leaving insert mode)
------------------------------------------------------------------------------
6.6. `g:jedi#show_call_signatures` *g:jedi#show_call_signatures*
Jedi-vim can display a small window detailing the arguments of the currently
completed function and highlighting the currently selected argument. This can
be disabled by setting this option to 0. Setting this option to 2 shows call
signatures in the command line instead of a popup window.
Options: 0, 1, or 2
Default: 1 (Show call signatures window)
Note: 'showmode' must be disabled for command line call signatures to be
visible.
Note: This setting is ignored if |g:jedi#auto_initialization| is set to 0. In
that case, if you want to see call signatures, you have to set it up
manually by calling a function in your configuration file: >
call jedi#configure_call_signatures()
------------------------------------------------------------------------------
6.7. `g:jedi#show_call_signatures_delay` *g:jedi#show_call_signatures_delay*
The delay to be used with |g:jedi#show_call_signatures|. If it is greater
than 0 it will use Vim's |CursorHoldI| event instead of |CursorMovedI|.
It will temporarily set Vim's |'updatetime'| option during insert mode.
Options: delay in milliseconds
Default: 500
------------------------------------------------------------------------------
6.8. `g:jedi#use_tabs_not_buffers` *g:jedi#use_tabs_not_buffers*
You can make jedi-vim open a new tab if you use the "go to", "show
definition", or "related names" commands. When you leave this at the default
(0), they open in the current window instead.
Options: 0 or 1
Default: 0 (Command output reuses current window)
------------------------------------------------------------------------------
6.9. `g:jedi#squelch_py_warning` *g:jedi#squelch_py_warning*
When Vim has not been compiled with +python, jedi-vim shows a warning to that
effect and aborts loading itself. Set this to 1 to suppress that warning.
Options: 0 or 1
Default: 0 (Warning is shown)
------------------------------------------------------------------------------
6.10. `g:jedi#completions_enabled` *g:jedi#completions_enabled*
If you don't want Jedi completion, but all the other features, you can disable
it in favor of another completion engine (that probably also uses Jedi, like
YCM).
Options: 0 or 1
Default: 1
------------------------------------------------------------------------------
6.11. `g:jedi#use_splits_not_buffers` *g:jedi#use_splits_not_buffers*
If you want to open new split for "go to", you could set this option to the
direction which you want to open a split with.
Options: top, left, right, bottom or winwidth
Default: "" (not enabled by default)
Note: with the 'winwidth' option the window is split vertically or horizontally
depending on the width of the window relative to 'textwidth'. This essentially
means that if the window is big enough it will be split vertically but if it is
small a horizontal split happens.
------------------------------------------------------------------------------
6.12. `g:jedi#force_py_version` *g:jedi#force_py_version*
If you have installed multiple Python versions, you can force the Python
version that is going to be used.
You don't have to compile VIM with multiple Python versions.
The variable can be set in the .vimrc like this to force python 2:
let g:jedi#force_py_version = 2
By default jedi loads the latest Python version installed on your system that
can be found.
This variable can be changed during runtime.
Options: 2, 2.7, 3, 3.5, 3.6, ...
Default: "auto"
------------------------------------------------------------------------------
6.13. `g:jedi#smart_auto_mappings` *g:jedi#smart_auto_mappings*
When you start typing `from module.name<space>` jedi-vim automatically
can add the "import" statement and trigger the autocompletion popup.
You can enable this using: >
let g:jedi#smart_auto_mappings = 1
<
Options: 0 or 1
Default: 0 (disabled by default)
------------------------------------------------------------------------------
6.14. `g:jedi#use_tag_stack` *g:jedi#use_tag_stack*
Write results of |jedi#goto| to a temporary file and use the |:tjump| command
to enable full |tagstack| functionality. Use of the tag stack allows
returning to the usage of a function with CTRL-T after exploring the
definition with arbitrary changes to the |jumplist|.
Options: 0 or 1
Default: 1 (enabled by default)
------------------------------------------------------------------------------
6.15. `g:jedi#environment_path` *g:jedi#environment_path*
*b:jedi_environment_path*
To use a specific virtualenv or a specific Python version it is possible to
set an interpreter.
Both setting the directory and setting a project is working.
Examples: "/usr/bin/python3.9", "venv", "../venv", "../venv/bin/python"
The buffer-local variable `b:jedi_environment_path` can be used to override the
global variable `g:jedi#environment_path`.
Default: "auto"
------------------------------------------------------------------------------
6.16. `g:jedi#added_sys_path` *g:jedi#added_sys_path*
*b:jedi_added_sys_path*
To add extra sys_path.
The buffer-local variable `b:jedi_added_sys_path` can be used to add
additional extra sys_path.
Examples: ["../site-packages"]
Default: []
------------------------------------------------------------------------------
6.17. `g:jedi#case_insensitive_completion` *g:jedi#case_insensitive_completion*
*b:jedi_case_insensitive_completion*
0 to disable case insensitive completion.
1 to enable case insensitive completion (default).
The buffer-local variable `b:jedi_case_insensitive_completion` can be used to
override the global variable `g:jedi#case_insensitive_completion`.
Default: 1
