9483 :: compile-time avoid Exception statement

• drkameleon (orginal) [2022-09-21T17:24:14+02:00] view original

  In a proc, with static variables, I have somewhere:

  except SomeError as e:
     when not staticVarOn:
         raise e
      else:
         discard
  Run

  This obviously leads to 2 different versions of the proc: one (when staticVarOn is true) re-raising SomeError and another one, doing nothing.

  And it's that last one, I guess, that leads to the following hint (and the accompanying generated code):

  
  Hint: 'e' is declared but not used [XDeclaredButNotUsed]
  Run

  I have tried wrapping the whole except clause inside the when .. else construct, but it keeps looking for an except.

  Any idea how to altogether-avoid the except clause when staticVarOn is set?

  If all you're doing is reraising, you don't need the exception variable.

  except SomeError:
     when not staticVarOn:
        raise
     else:
        discard
  Run

  Worst case you can discard e.

  Spot on! Thanks a lot!

  For some reason, I took it for granted that raise expected a param, but - apparently - it doesn't.

  Thanks again! :)
