Ruby provides a String method to center a String object according to a width, passed in as a parameter.
The width does not include the String object’s length it is called upon, therefore a good trick to center a text is to add the String length plus an even number for the space surrounding it.
text = 'Nicky Larson'
text.center(text.length + 4) # => " Nicky Larson "
The default padding string is a whitespace (' ') but it can be modified:
text.center(text.length + 4, '*') # => "**Nicky Larson**"
