Addressable is a replacement for the URI implementation that is part of Ruby‘s standard library. It more closely conforms to the relevant RFCs and adds support for IRIs and URI templates.

Example usage:

require 'addressable/uri'

uri = Addressable::URI.parse("http://example.com/path/to/resource/")
uri.scheme
=> "http" 
uri.host
=> "example.com" 
uri.path
=> "/path/to/resource/"

title:

  Levenshtein Distance Algorithm

synopsis:

  The Levenshtein distance is a measure of how similar two strings s and t are,
  calculated as the number of deletions/insertions/substitutions needed to
  transform s into t. The greater the distance, the more the strings differ.

  The Levenshtein distance is also sometimes referred to as the
  easier-to-pronounce-and-spell 'edit distance'.
