Types

type NativeFunction

type NativeFunction = func(*Runtime, []interface{}) (interface{}, error)

type Runtime

type Runtime struct {
	Scopes []string
	// Scope names => Variable names => values
	Vars           map[string]map[string]interface{}
	Funcs          map[string]map[string]func(*Runtime, []interface{}) (interface{}, error)
	Methods        map[reflect.Type]map[string]func(*Runtime, []interface{}) (interface{}, error)
	Stdout, Stderr io.Writer
	Stdin          io.Reader
}
