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 get_deps_all(). 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, 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 hookspath() that only imports the desired modules can be added. One then uses get_deps_minimal() or 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

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.

kivy.tools.packaging.pyinstaller_hooks.add_dep_paths()

Should be called by the hook. It adds the paths with the binary dependencies to the system path so that pyinstaller can find the binaries during its crawling stage.

kivy.tools.packaging.pyinstaller_hooks.get_deps_all()

Similar to get_deps_minimal(), but this returns all the kivy modules that can indirectly imported. Which includes all the possible kivy providers.

This can be used to get a list of all the possible providers which can then manually be included/excluded by commenting out elements in the list instead of passing on all the items. See module description.

Returns:A dict with two keys, hiddenimports and excludes. Their values are a list of the corresponding modules to include/exclude. This can be passed directly to Analysis` with e.g.

a = Analysis(['..\kivy\examples\demo\touchtracer\main.py'],
            ...
             **get_deps_all())

kivy.tools.packaging.pyinstaller_hooks.get_deps_minimal(exclude_ignored=True, **kwargs)

Returns Kivy hidden modules as well as excluded modules to be used with Analysis.

The function takes core modules as keyword arguments and their value indicates which of the providers to include/exclude from the compiled app.

The possible keyword names are audio, camera, clipboard, image, spelling, text, video, and window. Their values can be:

True: Include current provider

The providers imported when the core module is loaded on this system are added to hidden imports. 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. Their values are a list of the corresponding modules to include/exclude. This can be passed directly to Analysis` with e.g.

a = Analysis(['..\kivy\examples\demo\touchtracer\main.py'],
            ...
             hookspath=hookspath(),
             runtime_hooks=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             **get_deps_minimal(video=None, audio=None))

kivy.tools.packaging.pyinstaller_hooks.get_factory_modules()

Returns a list of all the modules registered in the kivy factory.

kivy.tools.packaging.pyinstaller_hooks.get_hooks()

Returns the dict for the spec hookspath and runtime_hooks values.

kivy.tools.packaging.pyinstaller_hooks.hookspath()

Returns a list with the directory that contains the alternate (not the default included with pyinstaller) pyinstaller hook for kivy, kivy/tools/packaging/pyinstaller_hooks/kivy-hook.py. It is typically used with hookspath=hookspath() in the spec file.

The default pyinstaller hook returns all the core providers used using get_deps_minimal() to add to its list of hidden imports. This alternate hook only included the essential modules and leaves the core providers to be included additionally with get_deps_minimal() or get_deps_all().

kivy.tools.packaging.pyinstaller_hooks.runtime_hooks()

Returns a list with the runtime hooks for kivy. It can be used with runtime_hooks=runtime_hooks() in the spec file. Pyinstaller comes preinstalled with this hook.
