autointf

===============================================================================

.. image:: https://img.shields.io/dub/v/autointf.svg

    :target: https://code.dlang.org/packages/autointf

An helper-library to auto-generate interface implementation from a

template function.

Installation:

------------------------------------------------------------------------------

Using dub:

.. code-block:: json

    "dependencies": {

        "autointf": "*"

    }

Quickstart

==============================================================================

See example app:

.. code-block:: d

    import std.stdio;

    import autointf;

    class AutoJsonRpc(I) : I

    {

        private int id;

        private ReturnType!Func executeMethod(alias Func, ARGS...)(ARGS args)

        {

            import std.traits;

            import std.array : join;

            import std.conv : to;

            // retrieve some compile time informations

            alias RT    = ReturnType!Func;

            alias PTT   = ParameterTypeTuple!Func;

            enum  Name  = __traits(identifier, Func);

            string[] params;

            foreach (i, PT; PTT)

                params ~= to!string(args[i]);

            return `{"jsonrpc": "2.0", "method": "` ~ Name ~ `", "params": [`

                ~ params.join(",") ~ `], "id": ` ~ (id++).to!string() ~ "}";

        }

        mixin(autoImplementMethods!(I, executeMethod)());

    }

    interface IAPI

    {

        string helloWorld(int number, string str);

        @noAutoImplement()

        final string foo() { return "foo"; }

    }

    void main()

    {

        auto api = new AutoJsonRpc!IAPI();

        writeln(api.helloWorld(42, "foo"));

        // > {"jsonrpc": "2.0", "method": "helloWorld", "params": [42,foo], "id": 0}

        writeln(api.foo());

        // > foo

    }
