SayHello

Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file lib/say_hello. To experiment with that code, run bin/console for an interactive prompt.

TODO: Delete this and the text above, and describe your gem

Add this line to your application's Gemfile:

gem 'say_hello'

And then execute:

$ bundle

Or install it yourself as:

$ gem install say_hello

• Load the gem to use it

[wlin@wlin ~]$ gem install say_hello
Successfully installed say_hello-0.1

 => true
2.2.4 :002 > SayHello.say_to()
 => "Hello, Cara"
2.2.4 :003 > SayHello.say_to('Cara Wang')

• Use it from the command line directly

[wlin@wlin say_hello]$ gem install say_hello
[wlin@wlin say_hello]$ say_hello
Hello, My friend
[wlin@wlin say_hello]$ say_hello test
Hello, test
