3572 :: How to call original procedure from overloaded?

• r3d9u11 (orginal) [2018-02-22T20:46:43+01:00] view original

  Hi! Can I call "original" procedure from overloaded? I Can't find any example for this theme

  for example:

  proc `$` (x: int):string = "Integer " & ($x)
  echo 5
  Run

  is infinite recursion

  as solution a tried to make additional procedure

  proc toString (x: int):string = $x
  proc `$` (x: int):string = "Integer " & (x.toString())
  echo 5
  Run

  is it a "good practice" in Nim, or there exists another way? (maybe something like a super.<method> from python, or parent.<method> from C#, or base.<method> from C++?)

  What you want seems to be to define a $ proc for type int and call system.`$` from inside that proc.

  proc `$` (x: int):string = "Integer " & (system.`$`(x))
  
  echo 5
  Run

  
  $ ./t
  Integer 5
  
  Run

  I was not sure that echo() would call our new proc, but seems it does :-)
