Failure/Error: source: Pathname(filename).read

Platform: Windows
Ruby: 2.7.2

Trying to run dead_end on my spec files. I added --require dead_end to my .rspec file. I manually delete an end in my code and run which produces this backtrace:

C:\_Programs\COSMOS\COSMOS\cosmos>rspec spec\microservices\microservice_spec.rb

An error occurred while loading ./spec/microservices/microservice_spec.rb.

Oof, sorry about that. Thanks for the report!

Possibly just a Windows bug? I really enjoyed your RailsConf 2021 video!

Possibly just a Windows bug?

Turns out that it wasn't just windows, it was any path with a colon : in it. I'm surprised it's gone this far without anyone hitting this bug before. Fixed in #114 and released in 3.0.2. Can you try again and let me know if you hit additional issues?

I really enjoyed your RailsConf 2021 video!

Thanks! I had a ton of fun making it. I'm happy to hear you enjoyed it.

Works great! BTW what software did you use to make your video? Had to take a long time. I appreciate the effort!

That's great, thanks for checking!

I used keynote to make the slides. I heavily use/abuse "magic move" to make multiple slides transform so it looks like I'm just animating a single slide here's the full deck exported to PDF with my notes https://speakerdeck.com/schneems/rubyconf-beware-the-dreaded-dead-end.

Most every keynote trick I learned I picked up from Searls or Caleb Thompson.

Usually, I don't go quite so animation-heavy on my slides as it does take a ton of time. I first gave the talk as 10 minutes for !!con, then 25 for RubyKaigi and then 35 for Ruby conf, so I didn't have to make them all in one go, it was natural to expand a bit more each time.
