QAppImageUpdate

Note: QAppImageUpdate was formerly known as "AppImage Updater Bridge". As of v2.0.0 of the project, it is now known as QAppImageUpdate with breaking changes to everything. So if you want to use v1.x, you can use the git tag v1.1.9 which is latest version of v1.x

QAppImageUpdate is a delta updater based on the zsync algorithm for the AppImage format, Using this library you can delta update any AppImage file, That is, Only download the binary data which you need to get the latest version, Therefore saving your time and internet.

QAppImageUpdate is not the official library to do this stuff, The official library is here which is also written in C++ but with no real Qt support , Thats why this library is built.

This library gives absolute support for Qt, Infact, All you need is the minimal installation of Qt(i.e, base).

Features

Single Threaded , Non-Blocking API - Using Qt's Event Loop.(Optionally , You can use a seperate thread.)
Easy to Use API - Made some effort to match Qt's style.
Cyclic and Async API - The whole library is fully cyclic and Async.(Only signals and slots.)
Pure C++ - Ported most of the legacy Zsync code to C++.
No third party libraries needed - The reason why you want to use this library.
Drink the Qt Kool-aid - In a positive way.
Optional Decentralized Update with BitTorrent Protocol - Reduce load on server.

Witness it with your own eyes,

#include <QCoreApplication>
#include <QAppImageUpdate>

int main(int argc, char **argv) 
{
    QCoreApplication app(argc, argv);
    QAppImageUpdate updater;

    QObject::connect(&updater, &QAppImageUpdate::finished, 
		      &app, &QCoreApplication::quit);
    
    updater.setShowLog(true);
    updater.start();
    return app.exec();
}

Try it

See this library in action at this repo which reimplements the official AppImageUpdater Tool using this library.
