5405 :: Getting memory address of object into string

• drkameleon (orginal) [2019-10-26T08:42:07+02:00] view original

  So, I am creating a new instance of a ref object.

  If I do echo repr(obj), I get something like this:

  
  ref 0x10ba54390 --> [...object fields...]
  Run

  How can I get this "0x10ba54390" into a string? (I tried with addr, etc - but I'm confused...)

  echo obj.addr.repr

  Or

  repr(obj.addr)

  Or repr(addr(obj))

  Or similar

  I still have issues...

  I have some ref objects and trying to get the hex address of the objects using repr(addr(x)) but when trying to echo the value the output is ... whitespace(!).

  Is it possible that it has sth to do with my configuration and/or compilation options? I cannot explain it otherwise...

  I sometimes use $castint. If you like it hex just transform the integer into a hex string...

  Note that it's fine to use them for logging or debugging but otherwise the GC can and will move those ref addresses in memory for cycle detection purposes if you have a cyclic type (unless you compile with pure refcounting with no cycle detection or you tag your cyclic type acyclic).

  Thanks a lot!

  This worked beautifully:

  fmt"{cast[int](addr(OBJ)):#x}"
  Run
