Rag is a Ruby-based library designed to make it easy to perform aggregates on delimited data. It is still very experimental, but it will eventually support pluggable parsers and aggregators. Currently, it only supports block aggregators.

Cannot aggregate when all records are required
# Basic example class FooAggregator < Rag::Aggregator output(0).inject(0) do |acc,i| acc + i.to_i end end aggregator = FooAggregator.new("1\n2\n3") aggregator.aggregate # => [[6]]
No external dependencies required at this time
