This link shows how extension methods will be consumed within IronPython.
So in DeltaShell it looks something like this:
ProjectExtensions
[assembly: Microsoft.Scripting.Runtime.ExtensionType(typeof(Project), typeof(ProjectExtensions))]
namespace DeltaShell.Plugins.Scripting.Extensions
{
public static class ProjectExtensions
{
public static string Laugh(this Project project)
{
return "Hahaha";
}
}
}
