The EagleCAD gem provides tools for working with the files generated by the popular EagleCAD PCB design software.
Add this line to your application's Gemfile:
gem 'eaglecad'
And then execute:
$ bundle
Or install it yourself as:
$ gem install eaglecad
require 'eaglecad'
drawing = EagleCAD.read('my_schematic.sch')
drawing.write('cloned_schematic.sch')
