metagen/README.md

Metagen package is used to describe structures, interfaces, functions, RPC calls using DSL. 
This can be useful for codegen, bindings, etc.

Here is an example of some imaginary DSL:    
    
    #include enum.meta

    func GetPlayer(
        id : uint32
    ) : DataPlayer

    func Apply(
        fn : func(float, DataPlayer) : uint32
    )

    struct DataPlayer
        @POD @table:player @pkey:id
        id                : uint32
        version           : string @strmax:16
        gold              : uint8 @default:0 #bonus
        registered        : bool @default:true

        func Equals(
            o : DataPlayer
            v : uint32
        ) : bool,bool
    end

    struct ProtoBase
        id    : uint32
        title : string @strmax:16 @default:"Hello"
    end

    struct ProtoBuilding extends ProtoBase
        floors : int32
        arr : uint32[] @default:[1,2,3]
    end
