Method: PrettyPrint#breakable

Defined in:
lib/prettyprint.rb

#breakable(sep = ' ', width = sep.length) ⇒ Object

This tells “you can break a line here if necessary”, and a width\-column text sep is inserted if a line is not broken at the point.

If sep is not specified, “ ” is used.

If width is not specified, sep.length is used. You will have to specify this when sep is a multibyte character, for example.
