NAnt extension function, Project object

Question

Is there a way to access the Project object from a NAnt extension function, as can be done from an extension task?

In this example, I want to use the BaseDirectory property inside the Bar function:

[FunctionSet("foo", "Foo")]
public class FooFunctions : FunctionSetBase
{
 public FooFunctions(Project project, PropertyDictionary properties)
  : base(project, properties)
 {
  // When does this constructor gets called?
 }

 [Function("bar")]
 public static string Bar(string name)
 {
  return "Bar!"; // How to get at project.BaseDirectory?
 }
}

I'm new to NAnt extensions, so I don't know if this is even a valid question or if I should approach the problem differently.

Answer 1

Great question Tom. The abstract base class, FunctionSetBase, has a property called Project that you can access from the Bar function. However, I noticed that the Bar function is declared static, which is not always necessary (but not wrong).

The following should be completely legal in NAnt world:

Function("bar")]
public string Bar(string name)
{
    string baseDirectory = Project.BaseDirectory;
    return baseDirectory; 
}

Are you seeing any problems?
