11076 :: pointer repr

• enaaab460 (orginal) [2024-02-24T11:50:54+01:00] view original

  In the official systems manual, and other tutorials online, pointer.repr prints the memory address of the pointer and the value it points to.

  This is a direct copy from https://nim-lang.org/docs/system.html#addr%2CT

  
  var
    buf: seq[char] = @['a','b','c']
    p = buf[1].addr
  echo p.repr # ref 0x7faa35c40059 --> 'b'
  echo p[]    # b
  Run

  However when I try to run this exact code on nim 2.0.2 on windows 10, this is the return:

  
  ptr 'b'
  b
  Run

  my own code where I want to test copy vs move semantics of strings also has the same issue.

  How can I get the same output as the manual?

  This has been changed to produce more readable output. If you want to output the pointer value you can use something like $cast[uint](addr s[0]) for s being a string or a seq.
