  ranges.map do |(ref_from, ref_to)|

    else
      ref_part(ref_from)
    end
  end.join(',')
end

#ranges ⇒ Object

Returns an array of pairs, each one being the from and to for a range. For single verses, the same ref is repeated twice. This is most helpful for converting the entire passage into a SQL query, and in fact is exactly why this library was built. See github.com/seven1m/bible_api/blob/master/app.rb for an example.
