module MyNamespace

  class << self
    # I want this utility method available everywhere inside my namespace,
    # but I don't want to expose it in the API, so let's make it "protected."

# Here's a piece of functionality I need to access often inside my library. It breaks an int
# into an array of bits, with each bit's position in the int corresponding to its array
# index. This gives me a consise way to check to see if lots of different bits are set.
123.to_s(2).reverse.split("").map(&:to_i)

# So, where do I put this? Should I monkey-patch Fixnum?

    to_s(2).reverse.split("").map(&:to_i)

# you want to incorporate information from another model in the friendly_id.
class City < ActiveRecord::Base

  belongs_to :state
  has_friendly_id :city_and_state, :use_slugs => true

  # This will return something like "San Francisco, California". It can be used
  # as a display name in your views, and also as the basis of the friendly_id
  # because it will be processed by the plugin to remove spaces, punctuation,

Some random examples of Spanish words transcribed to International Phonetic Alphabet by my in-progress spanish linguistics library and phonology library.

If you're interested in this stuff, you may want to take a look at how it first transcribes orthography to a base IPA form, then applies phonological rules to the resulting sequence. Then, syllabification and stress rules are applied using the Sequence of Sonority princple.

I'm currently working on making the phonological rules configurable so that dialectical phenomena like [yeísmo](http://en.wikipedia.org/wiki/Ye%C
