= Geographic Searches With Postgres's Earthdistance and Cube Extensions

This program shows how to easily create a Postgres database that uses the Cube
and Earthdistance extensions to perform fast queries on geographic data.

Briefly, the problem this code solves is "show me all places within 50
kilometers of New York City."

I'm a fan of MiniTest::Spec. It strikes a nice balance between the simplicity of TestUnit and the readable syntax of RSpec. When I first switched from RSpec to MiniTest::Spec, one thing I was worried I would miss was the ability to add matchers. (A note in terminology: "matchers" in MiniTest::Spec refer to something completely different than "matchers" in RSpec. I won't get into it, but from now on, let's use the proper term: "expectations").

Understanding MiniTest::Expectations

Let's take a look in the code (I'm specifically referring to the gem, not the standard library that's built into Ruby 1.9):

# minitest/spec.rb

module MiniTest::Expectations

revans

# requires root permissions in /usr/bin/

star = String.new
8.times { star += "*" }
Star = "\n#{star * 3}\n"

def newblock string
    puts "\n#{Star}#{string}#{Star}\n"
end
