  <strong>Spitfire Package Manager (SPM)</strong>
</p>

<p align="center">
A package management library designed to handle automatic updates for Spitfire browser and all of its components.
</p>

### SPM is currently used in:
- [Spitfire Luncher](https://weforge.xyz/Spitfire/Luncher)
- [Spitfire Insaller](https://weforge.xyz/Spitfire/Installer)

### Example usage:

To use SPM for downloading, decompressing, and installing updates, implement the following example in your Go application:
```go
package main

import (
	"fmt"
	"runtime"

	spm "weforge.xyz/Spitfire/SPM"
)

func main() {
	// Define the packages to download
	specs := []spm.AppIndexEntry{
		{
			Name:    "spitfire-launcher",
			Release: "nightly",
			OS:      runtime.GOOS,
			Arch:    runtime.GOARCH,
			Type:    "launcher",
		},
		{
			Name:    "spitfire-browser",
			Release: "nightly",
			OS:      runtime.GOOS,
			Arch:    runtime.GOARCH,
			Type:    "browser",
		},
	}

	// -- Download --
    // spm.DownloadSpecified(specs) downloads specified packages to temp dir and decompresses them, making them ready for install by running "spm.InstallUpdates()".
	fmt.Println("Starting download and decompression...")
	if err := spm.DownloadSpecified(specs); err != nil {
		fmt.Println("Error downloading packages:", err)
		return
	}

	fmt.Println("Download complete. Proceeding with installation...")

	// -- Install --
    // Install and Download are separate as you cannot replace running binaries on Windows. So the final move to the correct folder is done by "spm.InstallUpdates()".
	if err := spm.InstallUpdates(); err != nil {
		fmt.Println("Error during installation:", err)
		return
	}

	// -- Register --
	// spm.RegisterApp() is primarily used to modify the Windows registry so it recognizes Spitfire Browser as an installed program. 
	// You shouldn’t need to run it more than once during installation. Also this function requires administrative privileges on Windows to work correctly.
	if err := spm.RegisterApp(); err != nil {
		fmt.Println("Error registering app:", err)
		return
	}

	fmt.Println("Installation completed successfully!")

    // -- Run --
    // This function detects the browser binary and runs it. Alternatively, you can also use spm.RunAndWait()
    spm.Run()
}
```
