Who's in Space?

Did you know you can find out exactly who’s in space right now? The Open Notify API provides that information. Visit http://api.open-notify.org/astros.json to see not only how many people are currently in space but also their names and which spacecraft they’re on.

Create a program that pulls in this data and displays the information from this API in a tabular format.

How to Use

1. In the terminal, open up irb or pry in the repo's directory.
2. Type load './api_parser.rb'
3. Type ApiParser.new.display to return a table that looks similar to the example below.

Example Output

There are 3 people in space right now:

Name                | Craft
--------------------|------
Gennady Padalka     | ISS
Mikhail Kornienko   | ISS
Scott Kelly         | ISS

Constraints

• Read the data directly from the API and parse the results each time the program is run. Don’t download the data as text and read it in.
• Solve the problem using object-oriented programming. You should have at least one class.
• Add unit tests if possible. At a minimum, write testable code.

Challenges

• Ensure that the width of the header is as long as the longest value in the column.
• Don’t repeat the name of the craft—group all people by craft.

Do Not Do This Challenge

• Can you reliably sort the results alphabetically by last name? Be careful—some people have spaces in their name, like “Mary Sue Van Pelt.”
