Generate single class for all functions from all header files

[puschie286]

We have a c++ library with many header files - currently the generated output file creates one class per header file.

We are new to CppSharp and struggle to find a way of combining all functions into a single class.
All helper seems to work on class, methods or functions but none handle (header) files itself.

Any suggestions how to achieve this ?

I think you should be able to manipulate the AST to support what you need, but needs some custom code on your side.

Can you show an example of the generated code and what you want to achieve?

Generated code looks something like this:

namespace NAME
{
    public unsafe partial class filename_1
    {
        public partial struct __Internal [...]

        public static int Function1 [...]

        public static int Function2 [...]
    }

    public unsafe partial class filename_2
    {
        public partial struct __Internal [...]
       
        public static void Function3 [...]

        public static int Function4 [...]
    }
}

what we want is is all functions in one class:

namespace NAME
{
    public unsafe partial class custom_merge_name
    {
        public partial struct __Internal [...]

        public static int Function1 [...]

        public static int Function2 [...]
       
        public static void Function3 [...]

        public static int Function4 [...]
    }
}

You can try to preprocess the AST in your Preprocess so all the methods are merged in a single class.

You should iterate through all the translation units in your context, and move all the declarations you want to see merged to the single output class.

Alternatively you could treat the generated code-as-is, and generate a separate code file either manually or with CppSharp utility classes (CodeGenerator) that calls back into the generated code static methods.

oh nice, that was easier than i thought^^ thanks for the advice
