First sets command used to load powerline: expected + values are ``"py"`` and ``"py3"``. Second sets function used in statusline, + expected values are ``"pyeval"`` and ``"py3eval"``. + + If ``g:powerline_pycmd`` is set to the one of the expected values then + ``g:powerline_pyeval`` will be set accordingly. If it is set to some other + value then ``g:powerline_pyeval`` must also be set. Powerline will not check + that Vim is compiled with Python support if ``g:powerline_pycmd`` is set to + an unexpected value. + + These values are to be used to specify the only Python that is to be loaded + if both versions are present: Vim may disable loading one python version if + other was already loaded. They should also be used if two python versions + are able to load simultaneously, but powerline was installed only for + python-3 version. + +Tmux statusline +=============== + +Add the following lines to :file:`.tmux.conf`, where ``{repository_root}`` is +the absolute path to the Powerline installation directory (see :ref:`repository +root `):: + + source "{repository_root}/powerline/bindings/tmux/powerline.conf" + +.. note:: + The availability of the ``powerline-config`` command is required for + powerline support. The location of this script may be specified via + the ``$POWERLINE_CONFIG_COMMAND`` environment variable. + +.. note:: + It is advised to run ``powerline-daemon`` before adding the above line to + tmux.conf. To do so add:: + + run-shell "powerline-daemon -q" + + to :file:`.tmux.conf`. + +.. warning:: + Segments which depend on current working directory (e.g. + :py:func:`powerline.segments.common.vcs.branch`) require also setting up + :ref:`shell bindings `. It is not required to use powerline + shell prompt, :ref:`components setting ` allows to + set up only powerline bindings for tmux without altering your prompt. + Without setting up shell bindings powerline will use current working + directory of *tmux server* which is probably not what you need. + + Segments which depend on environment like + :py:func:`powerline.segments.common.env.virtualenv` will not work at all + (i.e. they will use environment of the tmux server), tracking environment + changes is going to slow down shell a lot. + + In any case it is suggested to avoid both kinds of segments in tmux + :ref:`themes ` because even support for tracking current + directory is very limited: + + #. It works only in shell. Should you e.g. run Vim and run ``:cd`` there you + will get current working directory from shell. + #. It works only in local shell and requires configuring it. + #. Some shells are not supported at all. + +IPython prompt +============== + +For IPython<0.11 add the following lines to :file:`.ipython/ipy_user_conf.py`: + +.. code-block:: Python + + # top + from powerline.bindings.ipython.pre_0_11 import setup as powerline_setup + + # main() function (assuming ipython was launched without configuration to + # create skeleton ipy_user_conf.py file): + powerline_setup() + +For IPython>=0.11 add the following line to +:file:`~/.ipython/profile_default/ipython_config.py` file in the used profile: + +.. code-block:: Python + + c = get_config() + c.InteractiveShellApp.extensions = [ + 'powerline.bindings.ipython.post_0_11' + ] + +For IPython>=5.0 you may use the above set up, but it is deprecated.
