class

JSON::Tight::Formatter

Applies the layout strategies described on JSON::Tight. Build one directly instead of calling JSON::Tight.generate to reuse it across documents or to control the indent used by expanded layouts.

formatter = JSON::Tight::Formatter.new(width: 100, indent: 4)
formatter.format(STDOUT, value)
