Fprime import explicit cpp implementation in fpp files

[DentOpt]

Hi,

I am having a type which is defined in

Types/MyTypeSerializable.cpp
Types/MyTypeSerializable.cpp

Now I would like to use this type in a port which is defined in e.g. MyModule/MyComponentApp.fpp

module MyModule {

    queued component MyComponent {
         ...
         sync input port GetMyType: [1] Types.MyType
         ...
    }
}

How can I import such explicitly in cpp defined Types in fpp files, something alike

  include type "Types::MyType" from "../Types/MyType.hpp"

?
Thank you in advance

It looks like this is a C++ type that you want to use in an FPP model (as opposed to a FPP defined type for use in the FPP model). @bocchino is this possible? Or does the type need to be defined in FPP if it is to be used in an FPP model?

Hi,

thank you already for your answers!
In general this approach works, but is not compatible with the previous file naming convention

In the fpp I can use the abstract type

type MyTpe

Then it will generate include paths:

<include_header>Types/MyType.hpp</include_header>

So in order to make this work, I have to change the file names to

Types/MyType.hpp
Types/MyType.cpp

This is working. Is there any way on specifying the include path for the abstract type ?

<include_header>Types/MyTypeSerializable.hpp</include_header>

[bocchino]

If you want the include path to be Foo/Bar/MyType.hpp, then you can define the type MyType in a model file Foo/Bar/MyType.fpp. In general the location of the header path for an FPP type T is the location of the model file where T is defined.

Hi, for the path that's clear, but does not solve the issue with the file name Foo/Bar/MyTypeSerializable.hpp.
It would be good to have an option to be able to specify the include hpp, e.g.

type MyType at "MyComponent/MyTypeSerializable.hpp"

Yes, we could add that feature. I'll add it to the list of proposed new features. For now you can rename the file.

Excellent, thank you for your support!

Hello, What is the state on this?
@bocchino Do you have reference to the feature, please?

It's in the list of proposed FPP features: nasa/fpp#163.
