Amity

Amity is a utility to create simple patches to exitsing assemblies. Inspired by Harmony

Examples

The assembly

public class MyClass
{
    public void MyMethod() 
    {
        Console.WriteLine("Hello, World!");
    }
}

This assembly is saved in C:\MyAssembly.dll

The patch

public class MyPatch {
    [AmityPatch(typeof(MyClass), "MyMethod", AmityPatch.Mode.Prefix)]
    public static void Patch() 
    {
        Console.WriteLine("Hello from Amity!");
    }
}

Applying the patch

public class Program
{
    public static void Main()
    {
        AmityInstance.Patch(typeof(MyPatch), @"C:\MyAssembly.dll", @"C:\MyNewAssembly.dll");
    }
}

Running this will generate the patched assembly in C:\MyNewAssembly.dll, the MyMethod() method in this assembly now looks like this:

public void MyMethod() 
{
    Console.WriteLine("Hello from Amity!");
    Console.WriteLine("Hello, World!");
}
