Rifter stands for: "Rifter Is a Fitting Tool, Entirely in Ruby", which is a recursive acronym, how cool is that? It is an engine for fitting ships in Eve Online game, packaged as a Ruby gem. Well, it's no longer entirely in Ruby. It uses libdogma (https://github.com/osmium-org/libdogma) under the hood.
This gem is extracted from GenEFT application.
I took some code from PyFa and translated to Ruby (mostly related to calculation of turrets/missiles damage). These fragments are marked with links to respective code pieces on PyFa github page.
Add this line to your application's Gemfile:
gem 'rifter', github: 'cthulhu666/rifter'And then execute:
$ bundle
As this gem is pretty much niche, it is not published to RubyGems.
- checkout repo
- download eve database dump from https://www.fuzzwork.co.uk/dump/sqlite-latest.sqlite.bz2 and unzip it
- run importer:
MONGOID_ENV=development MONGODB_URL=localhost bundle exec rake importer:run - run console:
MONGODB_URL=localhost ./bin/console
Or, if using Docker:
- Points 1 & 2 same as above
- build image:
docker-compose build app - start mongo:
docker-compose --x-networking start mongodb - run importer:
docker-compose --x-networking run app rake importer:run MONGOID_ENV=development - run console:
docker-compose --x-networking run app
Rifter console can serve as a ship/modules brower. Check which cruisers are fastest:
q = Ship.cruisers.order( ['miscellaneous_attributes.max_velocity', :desc] )
q.limit(5).map { |s| [s.name, s.max_velocity] }Test an actual fitting:
f = ShipFitting.new(ship: Ship.find_by(name: 'Rifter'), character: Character.perfect_skills_character)
3.times { f.fit_module('150mm Light AutoCannon II').charge = Charge.find_by(name: 'EMP S') }

Specs require a complete database import. It is unusual, but as this code is so much grown together with data, I consider it a good decision. I use doubles sparingly and operate on real ships/modules most of the time.
