.. _cmd-funcsave:
funcsave - save the definition of a function to the user's autoload directory
=============================================================================
Synopsis
--------
.. synopsis::
funcsave FUNCTION_NAME
funcsave [-q | --quiet] [(-d | --directory) DIR] FUNCTION_NAME
Description
-----------
``funcsave`` saves a function to a file in the fish configuration directory. This function will be :ref:`automatically loaded <syntax-function-autoloading>` by current and future fish sessions. This can be useful to commit functions created interactively for permanent use.
If you have erased a function using :doc:`functions <functions>`'s ``--erase`` option, ``funcsave`` will remove the saved function definition.
Because fish loads functions on-demand, saved functions cannot serve as :ref:`event handlers <event>` until they are run or otherwise sourced. To activate an event handler for every new shell, add the function to the :ref:`configuration file <configuration>` instead of using ``funcsave``.
This is often used after :doc:`funced <funced>`, which opens the function in ``$EDITOR`` or ``$VISUAL`` and loads it into the current session afterwards.
To view a function's current definition, use :doc:`functions <functions>` or :doc:`type <type>`.
