Re: Can I throw errors with custom fields?

[PMunch]

Of course, just add the fields to your exception type:
    
    
     Nim
    type
      MyException = ref object of Exception
        extraData: string
    
    
    proc raiseSomething() =
      var e: MyException
      new(e)
      e.extraData = "Hello world"
      e.msg = "This is the normal message"
      raise e
    
    try:
      raiseSomething()
    except MyException as e:
      echo e.msg
      echo e.extraData
    
    
    Run
