Python Visual Update Express

A dialog for updating an application by downloading files from a server. Designed to work like InstallForge's "Visual Update Express".

This software may only be used as described in the LICENSE file. Please contact me through a github issue for questions about commercial use.

Compatible with Python 3.10 and up

Installation

python3 -m pip install python-visual-update-express

Usage

Add updater window in python

Import the UpdaterWindow and configure it

from python_visual_update_express import UpdaterWindow

UPDATE_BASE_URL = 'https://yoursite.com/releases/yourapplication/'
CURRENT_VERSION = '1.0.1'
UPDATE_TARGET_DIR = 'C:/yourlocationpath'

# If you are using have a PyQt6 QApplication set up, please indicate this to the UpdaterWindow by 
# setting the create_q_application parameter to 'False'.
# Otherwise the UpdateWindow will create another QApplication, causing issues with PyQt.
# If you don't have a PyQt6 QApplication set up, please omit the create_q_application parameter 
# so the updater will set a QApplication up internally.
updater_window = UpdaterWindow(UPDATE_BASE_URL, CURRENT_VERSION, UPDATE_TARGET_DIR, False)

Then when you are ready, simply call show on the window to start the updater:

updater_window.show()

Update script

The updater works according to an updatescript.ini file on the server. This file tells the updater what versions of the application are supported and how to perform updates. Make sure to have this file available on the server URL used by the updater.

This is a very simple example of an updatescript.ini:

releases{
    1.0.0
    1.0.1
}

release:1.0.0{

}

release:1.0.1{
    DownloadFile:some-file.txt
}

Script commands

Currently only 1 command is available:

DownloadFile

This command will download a file on the speficied path, starting from the given update base URL + 'Updates/'. So if for example the base URL of https://yoursite.com/releases/yourapplication/ has been configured, a DownloadFile: dir1/some-file.txt will download the file from https://yoursite.com/releases/yourapplication/Updates/dir1/some-file.txt
