Golang SDK Template

The Go template generates a Golang module based on the module name and exposes clean interfaces based on the module interface. A core API which contain the single source of truth and a module code which is created as scaffolding code. For each interface a test file is also created.

The Go module allows to be extended and implemented based on the API core and the scaffolding files.

Following template feature switches are supported:

• API - Only creates the interface files for you
• Scaffold - Creates a full project with reference implementation and build system support.

In the generated source code you will find a README which explain in great detail how to build and use the code.

API

Interfaces

An interface like this counter will be directly transformed to an abstract C++ class.

interfaces:
  - name: Counter
    properties:
      - name: count
        type: int
    operations:
      - name: increment

The class will then later be used to be implemented by the customer.

type Counter interface {
    GetCount() int
    SetCount(count int)
    Increment()
}

Data Structures

A data structure like this message which contains one field, called text is transformed into a C++ class with public fields.

structs:
  - name: Message
    fields:
      - name: text
        type: string

A data structure is transformed to a Go struct type. As these API structs shall be able to be used outside of the module the fields are public.

type Message struct {
    Text string = ""
}

Enumerations

A enumeration will be transformed to a set of constants.

enums:
  - name: Direction
    members:
      - name: Up
      - name: Down
      - name: Left
      - name: Right

This is transformed to

type Direction int

const (
  Up = 1
  Down = 2
  Left = 3
  Right = 4
)
