#format(ruby, newline = true) ⇒ Object

Formats the Ruby source code for reabable output in the -fs formatter option. If the source contains no newline characters, wraps the source in single quotes to set if off from the rest of the description string. If the source does contain newline characters, sets the indent level to four characters.
