6214 :: Get an object defined by macro in a proc

• Pixeye (orginal) [2020-04-14T16:24:25+02:00] view original

  So I create an object via a macro. Everything works well

  ecs.group players:
      comps: CHealth
      scope: public
  Run

  this object has sequence of proc pointers. I can add action via macro

  ecs.group players:
      comps: CHealth
      scope: public
      event: handle_event
  
  proc handle_event*() =
      for e in players.added:
          log e
  Run

  This proc is for handling entities events. The thing is that group players is treated as an undeclared identifier inside of handle_event.

  But if I just manually define group like in code below everything works.

  var g = Group()
  g.actions.add(handle_event)
  
  proc handle_event*() =
      for e in g.added:
          log e
  Run

  What am I missing? I dumped astgen and pretty sure that wrote macro correctly

  I guess I found a solution. This language makes me insane XD

  ecs.group players:
      comps: CObject
      scope: public
  
  players.handle:
      for e in this.added:
          log e, "added"
      for e in this.removed:
          log e, "removed"
  
  Run

  template handle*(self: Group, code: untyped): untyped =
      self.events.add((this :GroupEvent) => code )
  Run
