The ruby cheers exercise (see: elizabrock/cheers), this time 3 weeks into learning Ruby, with tests!

Instructions

(What is the class supposed to do)

chmod +x filename to make a file executable

Specifications, for non-interactive version of cheers

(How does the program work)

Help Usage

Run the program by running ./cheers

The program will print out:

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

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

Regular Usage

Run 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... Y

Abby’s just GRAND!

Follow the proper grammatical for a and an. The rule is based on whether the spelling of a letter would begin with a vowel.
Skip non-word characters when printing the cheer (e.g. "Give me a..." lines)
Print the user's name out as it was originally input for the "just GRAND" line

After printing the cheer, the program outputs the number of days until the user's birthday:

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

If there was no input for birthday, the program instead says:

I would wish you a Happy Birthday, if I knew when that was!

If the input for birthday wasn't parseable, the program would instead say:

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

Specifications, for interactive version of cheers

(How does the program work)

Start the program by running ./cheers.rb

The program should ask:

Hello! What is your name?

The user types in their name, for example:

Abby

The program outputs a cheer in the following format:

Give me an... A

Give me a... B

Give me a... Y

Abby’s just GRAND!

If there was no input, ask again until valid input is provided
Follow the proper grammatical for a and an. The rule is based on whether the spelling of a letter would begin with a vowel.
Skip non-word characters when printing the cheer (e.g. "Give me a..." lines)
Print the user's name out as it was originally input for the "just GRAND" line

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

Hey, Abby, 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 tries again, but with the prompt:

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

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