Re: Initializing inherited types in Nim VM

[chrisheller]

By the way, this is now working properly on devel builds.
    
    
    # test of initializing inherited types in VM
    type
      SomeBaseObj  {.inheritable.} = object of RootObj
        txt : string
      
      InheritedFromBase = object of SomeBaseObj
        other : string
    
    proc initBase(sbo: var SomeBaseObj) =
      sbo.txt = "Initialized string from base"
    
    proc initInherited(ifb: var InheritedFromBase) =
      ifb.txt = "Initialized string from inherited"
    
    static:
      var bo: SomeBaseObj
      initBase(bo)
      doAssert(bo.txt == "Initialized string from base")
      
      var ifb1: InheritedFromBase
      initInherited(ifb1)
      doAssert(ifb1.txt == "Initialized string from inherited")
      
      var ifb2: InheritedFromBase
      initBase(SomeBaseObj(ifb2))
      # This assertion now passes because ifb2 does not get re-initialized
      echo ifb2.txt
      doAssert(ifb2.txt == "Initialized string from base")
    
    echo "Done"
