Why I'm Making This Guide

Oh my god there are so many freaking guides to Ruby's C API. Why make another one? Because from what I've seen of the others:

  • Most of them are outdated
  • Most fail to cover different approaches when they are available
  • Many cover only very specific use-cases
  • Many have bad recommendations
  • Many fail to explain when and why things are needed
  • Many try to be exhaustive rather getting the reader up and running quickly

And it struck me that all of these problems come from these guides largely being on media that do not promote community-driven updates. So I'm writing a new guide that doesn't suck and is on Github so you too can help make it not suck.
