Instance Method Details

#to_s ⇒ Object

Set#to_s is an alias of #inspect, so a tag list rendered itself as "#<Set: \"ruby\">". This is a user-facing value, so render it the way it was written.

Joins on the configured delimiter, so it round-trips through the parser. A parser subclass that overrides #delimiter privately — as the dummy app's CustomParser does — is not visible from here, so a tag list it produced renders with the configured delimiter rather than that parser's.
