mruby-go

The pure go mruby virtual machine implementation.

Roadmap

The priority task is to make the virtual machine available with limited functions, it still depends on mrbc command to compile RiteBinary.

• complete the method support
• complete the class support
• add mruby capability test

MRB_API

Golang has public and private method design and we can attach method to a struct. Therefore all public method is attach to *mruby.State in mruby-go as preferred method.

func (mrb *State) ObjectInstanceVariableGet(obj RObject, name Symbol) Value {
  return obj.ivGet(name)
}

// Prefer
func (mrb *State) ClassName(class RClass) string {
	if class == nil {
		return ""
	}

	name := mrb.ObjectInstanceVariableGet(class, _classname(mrb)) // <- Prefer this
	if name == nil {
		return ""
	}

	return name.(string)
}

// Avoid
func (mrb *State) ClassName(class RClass) string {
	if class == nil {
		return ""
	}

	name := class.ivGet(_classname(mrb)) // <- Avoid this
	if name == nil {
		return ""
	}

	return name.(string)
}
