A cross-platform library for adding automatic software updates to your macOS and Windows applications, using the Sparkle.framework on macOS and the WinSparkle.dll on Windows.

To use this crate, add it to your Cargo.toml:

[dependencies]
sparkle-updater = "0.1.0"

On macOS, you will need to include the Sparkle.framework in your application's bundle. You will also need to create an Info.plist file for your application, which should include the following keys:

<key>SUFeedURL</key>
<string>https://example.com/appcast.xml</string>
<key>SUEnableAutomaticChecks</key>
<true/>
<key>SUPublicEDKey</key>
<string>Your Pubkey</string>

Replace https://example.com/appcast.xml with the URL of your appcast file, which contains information about your app's updates. SUEnableAutomaticChecks enables automatic update checks for your app. SUPublicEDKey specifies the base64-encoded public EdDSA key.

To use the sparkle-updater crate in your Rust code, create a new Updater instance:

use sparkle_updater::Updater;

fn main() {
    let updater = Updater::new();

    updater.check_for_updates();
}

On Windows, you will need to include the WinSparkle.dll in your application's directory, and include the public DSA key in your application's resource file. To do this, create a new .rc file for your application with the following contents:

// Public Key
// Used by WinSparkle
// Verify Signature using DSA public key
DSAPub DSAPEM "dsa_pub.pem"

This assumes that your DSA public key file is named dsa_pub.pem. Make sure to include this file in your app.

To use the sparkle-updater crate in your Rust code, create a new Updater instance:

use sparkle_updater::Updater;

fn main() {
    let updater = Updater::new(
        "https://example.com/appcast.xml",
        "Software\\MyApp",
        None,
    );

    updater.check_for_updates();
}

The first parameter to new() is the URL for the appcast file, while the second parameter is the path in the registry where WinSparkle will store its settings. The third parameter is an optional callback function for handling shutdown requests during updates.

Thanks to the Sparkle project and the WinSparkle project for creating the libraries that this crate depends on.

The Sparkle provides a robust and easy-to-use solution for adding automatic software updates to macOS applications, while the WinSparkle provides a similar solution for Windows applications.

Without these projects, it would be much more difficult to add automatic update functionality to our applications. We are grateful for the hard work and dedication of the developers who created and maintain these libraries, and we encourage everyone to check out their projects and contribute if possible.

Thank you, Sparkle and WinSparkle teams!
