  • files-with-urls-only: print only for files with urls in them.
  • fails-only: print only broken links.
  • success-only: print only working links.
  • none: no files or urls prints.

Awesome! I’ll make some time to review this week.

I think I’ve changed my mind about this feature - given the core use of url checker for CI runs, it feels like feature bloat, and I’m not convinced that this is the cleanest implementation to insert a bunch of random if/else all over the library. Implementing this with a logger type interface that calls a statement based on a level would be much more elegant. I think the work is still valuable and we should keep the PR for future feedback but I am not wanting to add this now to the library. Thanks for your work on this @SuperKogito though!
