# Maze Solver

Primarily, this repository is a hypermedia client for applications that

serve [maze+xml](http://amundsen.com/media-types/maze/).

Secondarily, this repository demonstrates refactoring from a simple procedural

Ruby program to an OO one.

Well, as [much as 'refactoring' is without any tests](http://hamletdarcy.blogspot.com/2009/06/forgotten-refactorings.html),

anyway.

## Running

First of all, I ran this with Ruby 1.9.3. 1.9.2 should work just fine, too.

Secondly, you need some [nokogiri](http://nokogiri.org) to get going, so

`gem install` that right-off.

Finally, just `ruby solver.rb` to solve the maze.

## The procedural version

I started with a simple task: "request some XML with Net::HTTP" and slowly built

up some code. I pulled out some methods, and before you know it, I had a little

procedural maze solver.

You might be intereseted in following from the beginning. If so, check it [here](https://github.com/steveklabnik/maze_solver/tree/beginning)

You can read along with the commits to see how I built it by going [here](https://github.com/steveklabnik/maze_solver/compare/beginning...procedural).

You can see this version [here](https://github.com/steveklabnik/maze_solver/tree/procedural).

## The Refactoring

Commit early, commit often, that's what I always say! I tried to keep the

commits really tiny so you could see my process with each one. The easiest

way to follow along is probably on GitHub, you can see the list of commits

by going [here](https://github.com/steveklabnik/maze_solver/compare/procedural...objectoriented).

Check each one in order, as they build upon each other.

## The OO version

After the Great Refactoring, what's left is a shiny new version with lots of

objects. It happens to all of us eventually... anyway, you can check it

out [here](https://github.com/steveklabnik/maze_solver/tree/objectoriented).

## The Alternate TDD universe

... coming soon...
