# Ruby 1.9.2 has some neat stuff that lets us make a readable
# alternative case statement that calls each method in turn.

# 1.9.2 features used:
#   * hashes are ordered in 1.9.2
#   * cool JSON-style hash syntax
#   * concise lambda syntax

Rails 3.2 ships with a simple FileWatcher that only reloads your app if any of the files changed.

Besides, it also provides a mechanism to hook up your own file watcher mechanism, so we can use tools like FSSM that hooks into Mac OS X fsevents. This is an example on how to hook your own mechanism (you need Rails master, soon to be Rails 3.2):

1. Copy the 2_file_watcher.rb file below to lib/file_watcher.rb

2. Add the following inside your Application in config/application.rb

if Rails.env.development?

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

• rbenv
• ruby-build

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.
