nimforum mirror - Macro question: checking if variable is local, global or an argument of the procdef

Hi Hackers,

Inside of rather complicated macro that works on typed proc definition I am analyzing the procs body.

I am looking for reliable way to classify if the encountered symbol is:

Is there a reliable way to make the distinction?

I was thinking of adding to macros module:


   proc owner*(n: NimNode): NimNode {.magic: "SymOwner".}
     ## n should be a symbol

@Araq, Do you think it good idea?

Thanks

I'm not sure if the following works:

proc owner*(n: NimNode{nkSym}): NimNode = discard

Probably this would be better, as it is done in macros.nim

proc owner*(n:NimNode): NimNode=
  n.expectKind nnkSym

I don't know how to check for whether it is a global/local or scope symbol.
