fish_vcs_prompt - output version control system information for use in a prompt
===============================================================================

Synopsis
--------

::

     function fish_prompt
          echo -n (pwd)(fish_vcs_prompt) '$ '
     end

Description
-----------

The ``fish_vcs_prompt`` function displays information about the current version control system (VCS) repository, if any.

It calls out to VCS-specific functions. The currently supported systems are:

- :ref:`fish_git_prompt <cmd-fish_git_prompt>`
- :ref:`fish_hg_prompt <cmd-fish_hg_prompt>`
- :ref:`fish_svn_prompt <cmd-fish_svn_prompt>`

If a VCS isn't installed, the respective function does nothing.

The svn prompt is disabled by default because it's slow on large svn repositories. To enable it, modify fish_vcs_prompt to uncomment it. See :ref:`funced <cmd-funced>`.

For more information, see the documentation for each of the functions above.

Example
-------

A simple prompt that displays all known VCS info::

    function fish_prompt
        ...
        set -g __fish_git_prompt_showupstream auto
        printf '%s %s$' $PWD (fish_vcs_prompt)
    end
