iwyu_wrapper

A wrapper around iwyu that

  1. Returns 0 exit code on success (iwyu returns 2 as the exit code on success upto version 0.18)
  2. Allows passing in multiple files to check as args. Invoke iwyu_wrapper with same args as iwyu, but you can pass in multiple files to check in the form iwyu_wrapper <iwyu args> -- file1 file2
  3. Adds a --no-error flag to supress all errors and only print suggestions as warnings
