| require 'json' | |
| JSON.parse(ARGF.read).map do |package, value| | |
| package_name = package.split('@')[-2] | |
| puts "\n" | |
| if value["url"] | |

This is a quick attempt to participate in Jadi's contest. If this gist doesn't make any sense to you, just ignore it :)
Usage example: ruby heram.rb 1 2 6 6 70_000_000 4
for instructions, run without arguments (ruby heram) or just read the source!
human readable results will be printed on STDERR, Comma Separated Value (CSV) format will be printed to STDOUT, so you can ruby heram.rb 1 2 6 6 70_000_000 4 > results.csv and maybe xdg-open results.csv to plot it with your program of choice :)
With Gnuplot installed you can do something like this: ruby heram.rb 1 2 6 6 70_000_000 4 | gnuplot "plot.gp" > test.png && xdg-open test.png to generate a plot with Gnuplot file (plot.gp) provided here.
