Today I published my first Ruby Gem on rubygems.org
I've made gems before, mainly extensions to the Spree E-Commerce platform, but this was the first time I went through the correct process of building it from scratch, doing CI integration and all that jazz.
It's a small tool, which lets you get start and end dates of periods in a financial calendar used by the retail industry. Detailed Information can be found here.
Anyhoo, I've published it here: https://rubygems.org/gems/retail_calendar
The code is open-source and available here: https://github.com/kitwalker12/retail_calendar
Feel free to fork and contribute. Hope anyone finds it useful.
