    Overview
    --------------


|kitty| is highly customizable, everything from keyboard shortcuts, to rendering
frames-per-second. See below for an overview of all customization possibilities.

You can open the config file within |kitty| by pressing :sc:`edit_config_file`
(:kbd:`⌘+,` on macOS). A :file:`kitty.conf` with commented default
configurations and descriptions will be created if the file does not exist.
You can reload the config file within |kitty| by pressing
:sc:`reload_config_file` (:kbd:`⌃+⌘+,` on macOS) or sending |kitty| the
``SIGUSR1`` signal with ``kill -SIGUSR1 $KITTY_PID``. You can also display the
current configuration by pressing :sc:`debug_config` (:kbd:`⌥+⌘+,` on macOS).

.. _confloc:

|kitty| looks for a config file in the OS config directories (usually
:file:`~/.config/kitty/kitty.conf`) but you can pass a specific path via the
:option:`kitty --config` option or use the :envvar:`KITTY_CONFIG_DIRECTORY`
environment variable. See :option:`kitty --config` for full details.

**Comments** can be added to the config file as lines starting with the ``#``
character. This works only if the ``#`` character is the first character in the
line.

**Lines can be split** by starting the next line with the ``\`` character.
All leading whitespace and the ``\`` character are removed.

.. _include:

You can **include secondary config files** via the :code:`include` directive. If
you use a relative path for :code:`include`, it is resolved with respect to the
location of the current config file. Note that environment variables are
expanded, so :code:`${USER}.conf` becomes :file:`name.conf` if
:code:`USER=name`. A special environment variable :envvar:`KITTY_OS` is available,
to detect the operating system. It is ``linux``, ``macos`` or ``bsd``.
Also, you can use :code:`globinclude` to include files
matching a shell glob pattern and :code:`envinclude` to include configuration
from environment variables. Finally, you can dynamically generate configuration
by running a program using :code:`geninclude`. For example::

     # Include other.conf
     include other.conf
     # Include *.conf files from all subdirs of kitty.d inside the kitty config dir
     globinclude kitty.d/**/*.conf
     # Include the *contents* of all env vars starting with KITTY_CONF_
     envinclude KITTY_CONF_*
     # Run the script dynamic.py placed in the same directory as this config file
     # and include its :file:`STDOUT`. Note that Python scripts are fastest
     # as they use the embedded Python interpreter, but any executable script
     # or program is supported, in any language. Remember to mark the script
     # file executable.
     geninclude dynamic.py


.. note:: Syntax highlighting for :file:`kitty.conf` in vim is available via
   `vim-kitty <https://github.com/fladson/vim-kitty>`__.

Sample kitty.conf
--------------------

.. only:: html

    You can download a sample :file:`kitty.conf` file with all default settings
    and comments describing each setting by clicking: :download:`sample
    kitty.conf </generated/conf/kitty.conf>`.

.. only:: man

   You can edit a fully commented sample kitty.conf by pressing the
   :sc:`edit_config_file` shortcut in kitty. This will generate a config file
   with full documentation and all settings commented out. If you have a
   pre-existing :file:`kitty.conf`, then that will be used instead, delete it to
   see the sample file.

A default configuration file can also be generated by running::

    kitty +runpy 'from kitty.config import *; print(commented_out_default_config())'

This will print the commented out default config file to :file:`STDOUT`.
