-
-  This version of the GNU Lesser General Public License incorporates
-the terms and conditions of version 3 of the GNU General Public
-License, supplemented by the additional permissions listed below.
-
-  0. Additional Definitions.
-
-  As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the GNU
-General Public License.
-
-  "The Library" refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-
-  An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
-  A "Combined Work" is a work produced by combining or linking an
-Application with the Library.  The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
-  The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
-  The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
-  1. Exception to Section 3 of the GNU GPL.
-
-  You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
-  2. Conveying Modified Versions.
-
-  If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
-   a) under this License, provided that you make a good faith effort to
-   ensure that, in the event an Application does not supply the
-   function or data, the facility still operates, and performs
-   whatever part of its purpose remains meaningful, or
-
-   b) under the GNU GPL, with none of the additional permissions of
-   this License applicable to that copy.
-
-  3. Object Code Incorporating Material from Library Header Files.
-
-  The object code form of an Application may incorporate material from
-a header file that is part of the Library.  You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
-   a) Give prominent notice with each copy of the object code that the
-   Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the object code with a copy of the GNU GPL and this license
-   document.
-
-  4. Combined Works.
-
-  You may convey a Combined Work under terms of your choice that,
-taken together, effectively do not restrict modification of the
-portions of the Library contained in the Combined Work and reverse
-engineering for debugging such modifications, if you also do each of
-the following:
-
-   a) Give prominent notice with each copy of the Combined Work that
-   the Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the Combined Work with a copy of the GNU GPL and this license
-   document.
-
-   c) For a Combined Work that displays copyright notices during
-   execution, include the copyright notice for the Library among
-   these notices, as well as a reference directing the user to the
-   copies of the GNU GPL and this license document.
-
-   d) Do one of the following:
-
-       0) Convey the Minimal Corresponding Source under the terms of this
-       License, and the Corresponding Application Code in a form
-       suitable for, and under terms that permit, the user to
-       recombine or relink the Application with a modified version of
-       the Linked Version to produce a modified Combined Work, in the
-       manner specified by section 6 of the GNU GPL for conveying
-       Corresponding Source.
-
-       1) Use a suitable shared library mechanism for linking with the
-       Library.  A suitable mechanism is one that (a) uses at run time
-       a copy of the Library already present on the user's computer
-       system, and (b) will operate properly with a modified version
-       of the Library that is interface-compatible with the Linked
-       Version.
-
-   e) Provide Installation Information, but only if you would otherwise
-   be required to provide such information under section 6 of the
-   GNU GPL, and only to the extent that such information is
-   necessary to install and execute a modified version of the
-   Combined Work produced by recombining or relinking the
-   Application with a modified version of the Linked Version. (If
-   you use option 4d0, the Installation Information must accompany
-   the Minimal Corresponding Source and Corresponding Application
-   Code. If you use option 4d1, you must provide the Installation
-   Information in the manner specified by section 6 of the GNU GPL
-   for conveying Corresponding Source.)
-
-  5. Combined Libraries.
-
-  You may place library facilities that are a work based on the
-Library side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
-   a) Accompany the combined library with a copy of the same work based
-   on the Library, uncombined with any other library facilities,
-   conveyed under the terms of this License.
-
-   b) Give prominent notice with the combined library that part of it
-   is a work based on the Library, and explaining where to find the
-   accompanying uncombined form of the same work.
-
-  6. Revised Versions of the GNU Lesser General Public License.
-
-  The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
-  Each version is given a distinguishing version number. If the
-Library as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
-  If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

+Features
+========
+
+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)
+
 
 Installation
 ============
 
-You might want to use `pathogen <https://github.com/tpope/vim-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.
+You might want to use `pathogen <https://github.com/tpope/vim-pathogen>`_ or
+`vundle <https://github.com/gmarik/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.
 
-The autocompletion can be used with <ctrl+space>, if you want it to work with
-<tab> you can use `supertab <https://github.com/ervandew/supertab>`_.
+Example Installation Command using Pathogen:
+
+.. code-block:: sh
+
+    cd ~/.vim/bundle/ && git clone --recursive https://github.com/davidhalter/jedi-vim.git
 
 
-Options
-=======
+On Arch Linux, you can also install jedi-vim from official repositories as `vim-jedi
+<https://www.archlinux.org/packages/community/any/vim-jedi/>`__. It is also available
+on `Debian (≥8) <https://packages.debian.org/vim-python-jedi>`__ and `Ubuntu (≥14.04)
+<http://packages.ubuntu.com/vim-python-jedi>`__ as vim-python-jedi. On Fedora Linux,
+it is available as `vim-jedi <https://apps.fedoraproject.org/packages/vim-jedi>`__.
+
+Note that the `python-mode <https://github.com/klen/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 <http://github.com/davidhalter/jedi-vim/blob/master/doc/jedi-vim.txt>`_
+for details.

+FAQ
+===
+
+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:
 
 .. code-block:: vim
 
-    let g:jedi#autocompletion_command = "<C-Space>"
+    autocmd FileType python setlocal completeopt-=preview
 
-By default you get a window that displays the function definition you're
-currently in. If you don't want that:
 
-.. code-block:: vim
+I want <Tab> to do autocompletion
+---------------------------------
 
-    let g:jedi#show_function_definition = "0"
+Don't even think about changing the Jedi command to ``<Tab>``,
+use `supertab <https://github.com/ervandew/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
+<https://github.com/davidhalter/jedi-vim/issues/163>`__.
+
+
+Testing
+=======
+
+jedi-vim is being tested with a combination of `vspec
+<https://github.com/kana/vim-vspec>`_ and `py.test <http://pytest.org/>`_.
+
+The tests are in the ``test`` subdirectory, you can run them calling::

+==============================================================================
+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 2.5+ and 3.2+
+
+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.
+
+The jedi library has to be installed for jedi-vim to work properly.  You can
+install it first, by using e.g. your distribution's package manager, or by
+using pip: >
+
+    pip install jedi
+
+However, you can also install it as a git submodule if you don't want to use
+jedi for anything but this plugin. How to do this is detailed below.
+
+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*
+
+1a. Get the latest repository from Github: >
+
+    git clone http://github.com/davidhalter/jedi-vim path/to/bundles/jedi-vim
+
+1b. 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
+
+------------------------------------------------------------------------------
+2.1. 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 supports
+completion of a large number of 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
+- 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.jedidjah.ch.
+
+==============================================================================
+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_definitions_command`  *g:jedi#goto_definitions_command*
+Function: `jedi#goto_definitions()`
+Default: -                              Go to original definition
+
+NOTE: Deprecated. Use |g:jedi#goto_command| / |jedi#goto()| instead, which
+currently uses this internally.
+
+------------------------------------------------------------------------------
+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 occurences of the old variable name
+with the new one. The number of performed renames is displayed in the command
+line.
+
+------------------------------------------------------------------------------
+5.7. `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.
+
+------------------------------------------------------------------------------
+5.8. 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,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.
+
+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, jedi-vim shows the docstring of the currently selected
+item in a preview window. By default, 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.
+
+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 buffer instead.
+
+Options: 0 or 1
+Default: 0 (Command output is put in a new tab)
+
+------------------------------------------------------------------------------
+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 both python 2 and python 3, you can force which one jedi
+should use by setting this variable. It forces the internal Vim command, which
+will be used for every jedi call to the respective python interpreter.
+The variable can be set in the .vimrc like this to force python 3:
+
+let g:jedi#force_py_version = 3
+
+This variable can be switched during runtime using the following function:
+Function: `jedi#force_py_version_switch()`
+
+or set directly using this function, which has the same name as the variable:
+Function: `jedi#force_py_version(py_version)`
+
+Options: 2 or 3
+Default: "auto" (will use sys.version_info from "python" in your $PATH)
+------------------------------------------------------------------------------
+6.13. `g:jedi#smart_auto_mappings`                  *g:jedi#smart_auto_mappings*
+
+When you start typing `from module.name<space>` jedi-vim automatically
+adds the "import" statement and displays the autocomplete popup.
+
+This option can be disabled in the .vimrc:
+
+`let g:jedi#smart_auto_mappings = 0`
+
+Options: 0 or 1
+Default: 1 (enabled 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)
