Pyinstaller hooks
=================

Module that exports pyinstaller related methods and parameters.

Hooks
-----

PyInstaller comes with a default hook for kivy that lists the indirectly
imported modules that pyinstaller would not find on its own using
:func:`get_deps_all`. :func:`hookspath` returns the path to an alternate kivy
hook, ``kivy/tools/packaging/pyinstaller_hooks/kivy-hook.py`` that does not
add these dependencies to its list of hidden imports and they have to be
explicitly included instead.

One can overwrite the default hook by providing on the command line the
``--additional-hooks-dir=HOOKSPATH`` option. Because although the default
hook will still run, the `important global variables
<https://pythonhosted.org/PyInstaller/#hook-global-variables>`_, e.g.
``excludedimports`` and ``hiddenimports`` will be overwritten by the
new hook, if set there.

Additionally, one can add a hook to be run after the default hook by
passing e.g. ``hookspath=[HOOKSPATH]`` to the ``Analysis`` class. In both
cases, ``HOOKSPATH`` is the path to a directory containing a file named
``hook-kivy.py`` that is the pyinstaller hook for kivy to be processed
after the default hook.

hiddenimports
-------------

When a module is imported indirectly, e.g. with ``__import__``, pyinstaller
won't know about it and the module has to be added through ``hiddenimports``.

``hiddenimports`` and other hook variables can be specified within a hook as
described above. Also, these variable can be passed to ``Analysis`` and their
values are then appended to the hook's values for these variables.

Most of kivy's core modules, e.g. video are imported indirectly and therefore
need to be added in hiddenimports. The default PyInstaller hook adds all the
providers. To overwrite, a modified kivy-hook similar to the default hook, such
as :func:`hookspath` that only imports the desired modules can be added. One
then uses :func:`get_deps_minimal` or :func:`get_deps_all` to get the list of
modules and adds them manually in a modified hook or passes them to
``Analysis`` in the spec file.

Hook generator
--------------

:mod:`pyinstaller_hooks` includes a tool to generate a hook which lists
all the provider modules in a list so that one can manually comment out
the providers not to be included. To use, do::

    python -m kivy.tools.packaging.pyinstaller_hooks hook filename

``filename`` is the name and path of the hook file to create. If ``filename``
is not provided the hook is printed to the terminal.

This is the default if the keyword name is not specified. ``None``: Exclude Don't return this core module at all. ``A string or list of strings``: Providers to include Each string is the name of a provider for this module to be included. For example, ``get_deps_minimal(video=None, window=True, audio=['gstplayer', 'ffpyplayer'], spelling='enchant')`` will exclude all the video providers, will include the gstreamer and ffpyplayer providers for audio, will include the enchant provider for spelling, and will use the current default provider for ``window``. ``exclude_ignored``, if ``True`` (the default), if the value for a core library is ``None``, then if ``exclude_ignored`` is True, not only will the library not be included in the hiddenimports but it'll also added to the excluded imports to prevent it being included accidentally by pyinstaller. :returns: A dict with two keys, ``hiddenimports`` and ``excludes``.
