Unused variables #61

Closed maxChevSOL closed 1 year ago

maxChevSOL commented 1 year ago

Describe the bug

Iterators defined outside of their loop, a fortiriori when they are defined in a bigger scope than the conditional one where they are in used, get falsely interpreted as “unused variables”.

To Reproduce Steps to reproduce the behavior:

  1. Open any library/script where an iterator is declared outside of the loop(s) it is intended for.
  2. Run Ctrlpp Check for that specific library/script.
  3. Click on the error tab.
  4. A "unused variable" error message is to be seen.

Expected behavior The program should be able to interpret the pre-declaration of an iterator as a legitimate operation. Any variable playing the role of an iterator should not be described as an "unused" one.

Not reproducible with version 1.0.2. It rather produces style warning "scope can be reduced", which is OK.
