cheers_take_two

The ruby cheers exercise (see: bdfinlayson/ruby-cheers), this time three weeks into learning Ruby, with tests!

Instructions

Specifications, for non-interactive version of cheers

(How the program works)

Start the program by running ./cheers.rb Abby 08/25

The first argument is the user's name. The second argument is the user's birthday.

The program outputs a cheer in the following format:

Give me an... A

Give me a... B

Give me a... B

Give me a... Y

ABBY’s just GRAND!

• Should follow the proper grammatical rules for “a” vs. “an”, based on whether the first letter of the name is a vowel.
• Ignore all special characters (i.e. non-word characters) when printing the cheer (e.g., "Give me a...")
• Print the user's name out as it was originally inputted for the "just GRAND" line

If there was no input, the program would instead print out:

I'd cheer for you, if only I knew who you were :(

Try again with ./cheers [Name] [MM/DD Birthday]

After printing out the user's cheer, the program asks:

Hey, Bryan, what's your birthday? (mm/dd)

The user types in their birthdate

08/25

• If there was no input, asks again until valid input is provided
• If there was input that couldn't be parsed, the program prompts:

I couldn't understand that. Could you give that to me in mm/dd format?

The proram then outputs the number of days until the user's birthday

Awesome! Your birthday is in 45 days! Happy Birthday in advance!
