Constructor Details

#initialize ⇒ Text

Creates a new text object.

This constructor takes no arguments.

The workflow is to append a PrettyPrint::Text object to the buffer, and being able to call the buffer.last() to reference it.

As there are objects, use PrettyPrint::Text#add to include the objects and the width to utilized by the String version of this object.
