4278 :: Overloading string representation for objects

• enormandeau (orginal) [2018-10-04T20:18:31+02:00] view original

  I'd like to be able to use

   myobj
  Run

  and get a custom representation, not the standard

  (var1: value, var2: value)
  Run

  .

  How can I achieve this? What method (or proc?) do I need to overload?

  I tried overloading $ and repr but

   myobj
  Run

  still gave me the default string representation.

  I'm doing this for now:

  proc myrepr(o: Obj): string =
    return o.name & ": " & o.info
  
  echo myobj.myrepr
  Run

  But I would really like to be able to do:

  echo myobj  ## or echo myobj[]
  Run

  This is working fine for me:

  type
    Obj = object
      name, info: string
  
  proc `$`(o: Obj): string =
    return o.name & " " & o.info
  
  echo Obj(name: "Hi", info: "There")
  Run

  Works perfectly, thanks.

  I had the impression I had tried exactly that but I must have made a mistake somewhere.
