I was just trying to generate the documentation for my gem, and upon running either rdoc or yard I got the error

undefined method `intern' for []:Array

What is going on? I've trying reinstalling everything, and I'm on ruby 2.3.1. Also, from what I understand you can't use intern on an array, so why would rdoc and yard be trying to do that?

Edit

I've now investigated further, and it has something to do with my specific syntax, because my setup works on other files, just not mine. How can I check which file has the syntax issue?

RDoc Full Stack Trace (It seems identical to the YARD trace, but I've included both):

Wow @thesecretmaster I can't believe that you'd be so dumb to not realize that it was an issue with a specific piece of syntax that you used in README.md. It's about time that you opened an issue on the rdoc github page.
