Necessary Features

In order for a language to be called "implemented" in BMS, it needs to support the following features:

• Every script function which is registered on a type's namespace must:
  • Be callable on a ReflectReference representing object of that type in the script

  local my_reference = ...
  my_reference:my_Registered_function()
  

  • If it's static it must be callable from a global proxy object for that type, i.e.

  MyType.my_static_function()
  

• ReflectReferences must support a set of basic features:
  • Access to fields via reflection i.e.:

  local my_reference = ...
  my_reference.my_field = 5
  print(my_reference.my_field)
  

  • Basic operators and standard operations are overloaded with the appropriate standard dynamic function registered:
    • Addition: dispatches to the add binary function on the type
    • Multiplication: dispatches to the mul binary function on the type
    • Division: dispatches to the div binary function on the type
    • Subtraction: dispatches to the sub binary function on the type
    • Modulo: dispatches to the rem binary function on the type
    • Negation: dispatches to the neg unary function on the type
    • Exponentiation: dispatches to the pow binary function on the type
    • Equality: dispatches to the eq binary function on the type
    • Less than: dispatches to the lt binary function on the type
    • Length: calls the len method on ReflectReference or on the table if the value is one.
    • Iteration: dispatches to the iter method on ReflectReference which returns an iterator function, this can be repeatedly called until it returns ScriptValue::Unit to signal the end of the iteration.
    • Print: calls the display_ref method on ReflectReference or on the table if the value is one.
• Script handlers, loaders etc. must be implemented such that the ThreadWorldContainer is set for every interaction with script contexts, or anywhere else it might be needed.
