Adding your own range formats to to_formatted_s

You can add your own formats to the Range::RANGE_FORMATS
hash. Use the format name as the hash key and a Proc instance.
# config/initializers/range_formats.rb Range::RANGE_FORMATS[:short] = ->(start, stop) { "Between #{start.to_s(:db)} and #{stop.to_s(:db)}" }
# File lib/core_ext/range/conversions.rb, line 24 def to_formatted_s(format = :default) if formatter = RANGE_FORMATS[format] formatter.call(first, last) else to_default_s end end
