A presentation at Devoxx UK in in London, UK by Stéphane Philippart
Everyone uses CLIs (Command Line Interfaces), and they’ve been around since the dawn of time. Often synonymous with productivity gains, their creation is sometimes obscure and can seem complex.
This was the case a few decades ago, but in recent years, languages and frameworks have made it possible to write them simply in your favorite language. I propose to use a language which, at first glance, may not seem the most intuitive for creating a CLI: Java!
Thanks to Picocli and Quarkus, your CLI will have all the bells and whistles of a great CLI, yet be simple to develop! And the icing on the cake: we’ll create a “real” executable thanks to Graal VM.
Come and join me for a live coding session that will show you how to create a Java CLI with Picocli and Quarkus from scratch!
