A simple pinvoke generator based on xoofx/CppAst to generate C# for C/C++
Let's say we have a C++ class:
class Calculator {
public:
int add(int x, int y);
}Since it's a class and add is an instance method, we need to make it DllImport-friendly:
EXPORTS(Calculator*) Calculator_Calculator() { return new Calculator(); }
EXPORTS(int) Calculator_add(Calculator* target, int x, int y);Now we can easily bind it to C#:
public partial class Calculator : SafeHandle
{
public IntPtr Handle { get; private set; }
// API:
public Calculator() => this.Handle = Calculator_Calculator();
public int Add(int x, int y) => Calculator_add(Handle, x, y);
// DllImports
[DllImport("mylib")] private static extern int Calculator_add(IntPtr handle, int x, int y);
[DllImport("mylib")] private static extern IntPtr Calculator_Calculator();
}So the generator is able to generate C# classes and the C glue. As an example - see samples/SimdJson.
