2398 :: How to use --define:SYMBOL:VAL option?

• yuutayamada (orginal) [2016-07-22T02:47:36+02:00] view original

  I compiled following content with: nim c -r --define:line:10 foo.nim but I got: foo.nim(2.9) Error: undeclared identifier: 'line'

  How can I access the line variable? or Am I doing something wrong?

  when defined(line):
    echo line
  Run

  Thanks

  --define with a value can only be used to overwrite constants.

  nim c -r --define:line=10 foo.nim

  when defined(line):
    const line {.intdefine.} = 84
    echo line
  Run

  Thank you Araq! This option seems pretty handy.
