Avengers Tracker

HELP!

Against the best efforts of the Avengers, Thanos has successfully snapped the Infinity Gauntlet and elimitated 50% of the living creatures in the universe. Fortunately, you, an experienced Ruby developer at WYWM receives a transmission from Avengers HQ detailing the whereabouts and status of humanity's last hope. Using your super programming skills, you will build a tool to make sense of this final transmission. No pressure, but humanity is counting on you!

Initialization

Run the following command from within the project directory:

bin/setup

This will install the necessary dependencies.

Task

You will need to create an Avenger class in avengers.rb. This class will be initialized with name, location and status parameters and set those as instance variables (properties).

You will then need to create a Tracker class in tracker.rb.

Parse Transmission

The get_avengers_from_transmission_file() method will take the information stored in transmission.txt and store it into an instance variable @avengers as an array of Avenger objects. F.R.I.D.A.Y. thinks exploring the File class is a good place to start.

Get Avengers Statuses

Now that we have the Avengers stored in a more coherent way, finding out how the team is doing is your next task.

get_alive_avengers() should return an array of all avengers who's status is Alive.
get_missing_avengers() should return an array of all avengers who's status is Missing.
get_dead_avengers() should return an array of all avengers who's status is Dead.

Where Are They?

Ok, now that we have assessed the damage we need to figure out where everyone is. Your next task is to write a method to list the Avengers by their location. get_avengers_by_location() can do two things:

List all Avengers by their current location; and
List Avengers at a current location if you provide a location name as the optional parameter.

But what if we only want to find a single avenger? Let's get their location using find_avenger(). This will accept the Avenger's name (Iron Man) and return the name of their location.

Hmm...where on Earth is Ant Man?

Testing

To run tests, run the following command from within the project directory:

rspec

If all tests pass, pat yourself on the back, then get your butt to Avengers HQ and help save the world!

Trying It Out in Real Time

First, run the following command from within your project directory:

bin/start

We are now inside IRB, an interactive Ruby shell for your terminal. Next we will import our Tracker and Avenger classes and afterwards can interact with them normally using the Ruby language:

# import class
require './lib/tracker.rb' # => true
require './lib/avenger.rb' # => true

# Create instance
tracker = Tracker.new

# call method
tracker.find_avenger('Iron Man') # => 'Titan'
