Reflecting on a Type parameter


Reflecting on a Type parameter

seems to work fine Reflection in Idris is a purely syntactic, compile-time only feature. To predict how it will work, you need to know about how Idris converts your program to its core language. Importantly, you won't be able to get ahold of reflected terms at runtime and reconstruct them like you would with Lisp. Here's how your program is compiled:
Internally, Idris creates a hole that will expect something of type Type -> TT. It runs the proof script for foo in this state. We start with no assumptions and a goal of type Type -> TT. That is, there's a term being constructed which looks like ?rhs : Type => TT . rhs. The ?foo : ty => body syntax shows that there's a hole called foo whose eventual value will be available inside of body. The step intro t creates a function whose argument is t : Type - this means that we now have a term like ?foo_body : TT . \t : Type => foo_body. The reflect t step then fills the current hole by taking the term on its right-hand side and converting it to a TT. That term is in fact just a reference to the argument of the function, so you get the variable t. reflect, like all other proof script steps, only has access to the information that is available directly at compile time. Thus, the result of filling in foo_body with the reflection of the term t is P Bound (UN "t") (TType (UVar (-1))).

hop of those help? How can I reflect on the interfaces implemented by a given type (of class or interface) in .NET? , Call Type.GetInterfaces().

I hope this helps . This has poor interop. For example, consider this C# - F# example
C#:
code :
public class Class1
{
    public static void Foo(Func<object, string> f)
    {
        Console.WriteLine(f.Method.GetParameters()[0].Name);
    }
}
Class1.Foo(fun yadda -> "hello")

this one helps. Chars is an indexer in C# terminology - but a "property with index parameters" in .NET/CLR terminology... so you can only get the value by specifying arguments. So in this case, it's representing the indexer used here:
code :
char c = text[3];

will be helpful for those in need In your first version, fun is assigning to the parameter arr, which doesn't change the argument arr in main. In your second, you are making changes to what arr points to: the structures you wish to change.

help you fix your problem IDictionary is not serializable. Nor are the standard dictionaries. You will need to implement a custom dictionary type to enable serialization. Then it will work.
