Welcome. On this page you can find my software projects, my articles, my notes and my pictures.

My name is Christian Kruse. I work as a software developer and system administator at Termitel GmbH. I live in Germany in a small town called Steinfurt.

I am passionate about software development, GNU/Linux, FLOSS as well as macOS. I am also a do-it-yourself apologetic: I did a lot of things in and around my house myself. I love the hacker culture. And last but not least I am a dog owner.

This is my personal replacement for Twitter, Facebook and the other data silos. My content is mine — so if you are interested in my activity, just have a look at this page.

Sorting by multiple criterias in Elixir

Christian Kruse 5 months ago

Sometimes one wants to sort an Enum by multiple criterias; e.g. you want to sort a list of records first by name and then by creation date. Let’s get more specific, have a look at this list:

persons = [
  %{firstname: "Aleksei", lastname: "Magusev", location: "Gothenburg, Sweden"},
  %{firstname: "Andrea", lastname: "Leopardi", location: "L'Aquila, Italy"},
  %{firstname: "Eric", lastname: "Meadows-Jönsson", location: "Gothenburg, Sweden"},
  %{firstname: "Fernando", lastname: "Tapia Rico", location: "Amsterdam, Netherlands"},
  %{firstname: "James", lastname: "Fish", location: "Unknown"},
  %{firstname: "José", lastname: "Valim", location: "Kraków, Poland"}
]

We want to sort this list first by location, then by firstname and last by lastname. There are two easy solutions to this problem.
