Class: PrettyPrint::Text

Do not use. This class is for internal use only.

Overview

The Text class is the means by which to collect strings from objects.

This class is intended for internal use of the ::PrettyPrint buffers.

#width readonly

The total width of the objects included in this Text object.

#add(obj, width)

Include obj in the objects to be pretty printed, and increment this Text object’s total width by #width
#output(out, output_width)

Render the String text of the objects that have been added to this Text object.

Creates a new text object.

This constructor takes no arguments.

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

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