MagLev implementation of Ruby C extensions API.

This document explains the state of C extensions on Maglev. This is meant to become an exhaustive listing of the restrictions in the C API layer, their reasons, and how to work around them.

We also provide code examples for some workarounds at the end of this document.

If more restrictions are found, or you have code examples, please feel

Hacking Club Mate "imatate"

Read about the end result here

Join me when I start brewing my first batch of Club Mate. Inspired by a podcast from chaos radio express on the topic "Hackerbrausen" (Hacker's soda, listen here) I want to try this by myself.

So far I have bought all the necessary ingrediends and tools to get started. And with the help from Jan (@janl) I can even carbonate the end result :)

When? Where?

# Example documentation for a GET request:

#     param :state,     String, :default => 'open', :choices => %w(open closed)
