5053 :: Echo a NimNode

• vitreo12 (orginal) [2019-07-28T00:15:08+02:00] view original

  Hello everyone, I would need to debug the NimNodes returned from

  
  getImpl
  Run

  calls, and I was looking for a function that would print out a NimNode tree structure given a NimNode, not a block of nim code. I looked at

  
  dumpTree
  Run

  , but it is not working for NimNodes inside the macro. Is there such a function?

  On a similar topic,shouldn't

  
  echo
  Run

  support the printing of NimNodes?

  try

  echo treeRepr nimNode
  Run

  Thanks, it worked! Shouldn't dumpTree do exactly that?

  dumpTree takes an untyped value as it's first argument and then converts it into a NimNode before calling echo treeRepr on it

  Your untyped data has already been converted into a NimNode by passing it into a macro so you need to skip the conversion step.

  It's the same reason calling macros while already inside a macro is tricky.

  Thank you, it makes perfect sense.
