Instance Method Details

#array_paragraphs(fragments) ⇒ Object

The original purpose of this method is to split paragraphs, but our formatter only works on paragraphs that have been presplit. Therefore, we just need to wrap the fragments in a single-element array (representing a single paragraph) and return them.
