PyWinSparkle
============

About pywinsparkle
~~~~~~~~~~~~~~~~~~

An auto-update framework for frozen Python applications on Windows.

Pywinsparkle is a wrapper for the WinSparkle project originally
developed by Vaclav Slavik. WinSparkle is an update framework for
Windows.

The original WinSparkle project is located here: https://winsparkle.org/

github: https://github.com/vslavik/winsparkle

The current version of PyWinSparkle includes WinSparkle 0.5.7

Note: This is package is not affiliated with the original developer
Vaclac Slavik and is therefore technically unofficial.

Installation
~~~~~~~~~~~~

``pip install pywinsparkle``

Wheels are built for 32bit and 64bit versions of Windows, covering
Python 2.7 and all python version after 3.3

Note: If you are using one of the above versions pip throws and errror,
consider upgrading pip with ``pip install --upgrade pip``

Usage
~~~~~

All of the API function wrapper names are the same as the original
WinSparkle project. The only difference is in the argument types which
are either python strings or integers. For the callback functions, just
the function object is required (ie, the name of the function without
the parenthesis).

In pywinsparkle, I have not tested created Windows Resource files,
instead I have just been using ``win_sparkle_set_app_details()``
function. The Windows Resource files should work though. It is also
necessary to set the appcast url with ``win_sparkle_set_appcast_url()``.

Basic Example:

.. code:: python

    from pywinsparkle import pywinsparkle


    def no_update_found():
        """ when no update has been found, close the updater"""
        print("No update found")
        print("Setting flag to shutdown PassagesUpdater")


    def found_update():
        """ log that an update was found """
        print("New Update Available")


    def encountered_error():
        print("An error occurred")


    def update_cancelled():
        """ when the update was cancelled, close the updater"""
        print("Update was cancelled")
        print("Setting flag to shutdown PassagesUpdater")


    def shutdown():
        """ The installer is being launched signal the updater to shutdown """

        # actually shutdown the app here
        print("Safe to shutdown before installing")


    def main():

        # register callbacks
        pywinsparkle.win_sparkle_set_did_find_update_callback(found_update)
        pywinsparkle.win_sparkle_set_error_callback(callbacks.encountered_error)
        pywinsparkle.win_sparkle_set_update_cancelled_callback(update_cancelled)
        pywinsparkle.win_sparkle_set_did_not_find_update_callback(no_update_found)
        pywinsparkle.win_sparkle_set_shutdown_request_callback(shutdown)

        # set application details
        update_url = "https://winsparkle.org/example/appcast.xml"
        pywinsparkle.win_sparkle_set_appcast_url(update_url)
        pywinsparkle.win_sparkle_set_app_details("VendorName", "TestApp1", "1.0.0")

        # initialize
        pywinsparkle.win_sparkle_init()

        # check for updates
        pywinsparkle.win_sparkle_check_update_with_ui()

        # alternatively you could check for updates in the 
        # background silently
        pywinsparkle.win_sparkle_check_update_without_ui()

        # dont do it this way, just an example to keep the thread running
        while True:
            time.sleep(1)


    if __name__ == "__main__":
        main()

Freezing with Pyinstaller
~~~~~~~~~~~~~~~~~~~~~~~~~

Add an entry to .SPEC in Analysis for binaries.

Assuming you are using a virtual environment and it is called "venv" it
would look like this:

.. code:: python


    import platform

    if architecture == "64bit":
        winsparkle = 'venv\\Lib\\site-packages\\pywinsparkle\\libs\\x64\\WinSparkle.dll'
    else:
        winsparkle = 'venv\\Lib\\site-packages\\pywinsparkle\\libs\\x86\\WinSparkle.dll'

    a = Analysis(['Updater\\src\\main.py'],
                 pathex=['.'],
                 binaries=[(winsparkle, '.')],
                 datas=[],
                 hiddenimports=[],
                 hookspath=[],
                 runtime_hooks=[],
                 excludes=[],
                 win_no_prefer_redirects=False,
                 win_private_assemblies=False,
                 cipher=block_cipher)

The package contains DLL's for both 64bit and 32bit versions of python.
Adding the preceding code snippet makes it possible to switch between
versions of python seamlessly.
