Watch a screencast of gem usage here.
Usage
This gem is mainly useful for benchmarking code over a number of inputs. This input should be supplied in the form of an object capable of calling #each
.
Sample benchmarking script:
require 'benchmark/plot'
class TestArray
attr_reader :arr
def initialize arr
@arr = arr
end
def to_s
@arr.size.to_s
end
end
test_data = [5, 25, 50, 75, 100, 125, 150, 175, 200,250,300]
test_data.map! {|e| TestArray.new(Array.new(e) {|i| i}) }
Benchmark.plot(test_data) do |x|
x.report("map.flatten") do |data|
data.arr.map { [nil] }.flatten
end
x.report("flat_map") do |data|
data.arr.flat_map { [nil] }
end
end
