A long, long time ago...
I can still remember
How his blog used to make me smile.
And I knew that if he had his chance
That he could make their code enhance
And, maybe, they’d be happy for a while.

But August made me shiver
With every code line I’d deliver.
Bad news on the doorstep;

This readme is a mixture of everything I read on SO+nokogiri wiki, which ultimately worked out for me.

Here are the steps which worked for me to get rid of segfaults with Nokogiri 1.4.4, on both Lion and Snow Leopard, with Ruby 1.8.7 (patchlevel 334 and +).

First diagnose which version of libxml2 you're using:

bundle exec nokogiri -v

If you have 2.7.3 listed somewhere, you're in bad waters (known to segfault). Install this:

# Traversing arrays and objects in CoffeeScript

# The array and object we use for testing
arr = [1, 2, 3, 4, 5]
obj = {a: 1, b: 2, c: 3, d: 4, e: 5}


# 'in' has a different meaning in CoffeeScript than in JavaScript
# CS: element in array -> JS: array.indexOf(element) >= 0
console.log '5 in arr: ' + (5 in arr)

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.
