You start with a terrain key and a layout string. Then you break the text into lines to get your rows. Ignore any white space. This is nice because it means you can have spaces at the beginning of the lines if you have maps embedded in your source code and want to tab indent them to the level of the surrounding code. Of course, there would be advantages to leaving the spaces alone, too. Then you could use them to represent a Terrain type, perhaps whatever the normal Terrain type of a Map was for cleaner layout. If you wanted to take that approach, you d need to cut the gsub call that removes the spaces. Anyway, you now have your two-dimensional array of character data. All that remains is to create the Matrix instances and insert the appropriate Terrain types based on the characters. The calls to each_with_index let you easily iterate through the arrays retrieving both the data stored in them and the locations it is stored at. This lets you easily copy it over to the @terrain Matrix, translating it through the terrain key on the way. How about an example of all this in use

mapconnect '/weather/:year/:month/:date, :controller => 'weather', :action => 'archive' While the mapconnect method was fine for awhile, it did cause Rails developers to be a bit too verbose a bit too often, when they wanted to refer to a specific route If we wanted to create a link to the preceding routes, the correct way would have been link_to 'Home', :controller => 'home', :action => 'welcome' link_to 'Show Post', :controller => 'post', :action => 'show', :id => @post link_to 'Weather Last Christmas', :controller => 'weather', :action => 'archive', :year => '2006' :month => '12', :date => '25' You can see how quickly it would become bothersome to constantly generate links by manually typing the controller, actions, and ID parameters each time, and you can imagine how quickly this was increasing the noise ratio within our view files.

Once you ve selected the New Video Source option, you ll see the setup screen for the guide data source. Figure 4-11 shows an example of a U.K. TV guide being set up.

Named routes were added to our Rails arsenal to ease this pain for Rails developers Building a named route is almost identical to building a regular route except that we replace the connect method with a custom name of our own choosing for the route So to convert the regular routes you saw previously, you might write them like this: maphome '', :controller => 'home', :action => 'welcome' mappost '/post/:id', :controller => 'post', :action => 'show' mapweather_archive '/weather/:year/:month/:date, :controller => 'weather', :action => 'archive' While this may seem like just a minor change, it makes a big difference for us When we create a named route, Rails provides us with two new URL methods that make our lives much easier: {named_route}_path and {named_route}url So our previous map.

Figure 4-11. Setting up a U.K. guide data source When you hit Finish, then the progress bar will stall at 50 percent for guide data sources that aren t for the Zap2it North American guide data, as shown in Figure 4-12. It s not a crash; it s just mythtv-setup waiting for you to configure the XMLTV grabber on the terminal you started mythtv-setup from (remember we said to start it in a real terminal window ).

class Map def all_positions @terrain.all_positions end def within (distance, x1, y1, x2, y2) (x1 - x2).abs + (y1 - y2).abs <= distance end def near_positions(distance, x, y) all_positions.find_all{|x2, y2| within (distance, x, y, x2, y2) } end end

The all_positions method just passes responsibility off to the Matrix class (whose all_positions method you ve already looked at). The within method is a little more interesting. It calculates whether the Manhattan distance between two points is less than a certain number. Despite the fact that I ve obviously included it in the preceding code, I honestly don t believe it belongs in the Map class! It uses none of the class s instance variables or methods and only operates on its parameters. This is always a clue that a method actually belongs to another class! In this case, however, because you are using unencapsulated x and y coordinates, there is no class to attach the method to. Since the Map class is related, attaching the method here is a satisfactory alternative. Finally, near_positions uses the other two methods to return a list of nearby locations.
