As developers, we often have to create command-line applications, which expose APIs, workflows or data processing functionality in a way that is accessible to scripts and non-developers. Although a simple command-line application can be created by only using Array[String], such applications lack features that users take for granted, including:

• Flexible subcommands

• Options

• Arguments

• Validations

• Documentation pages

In this presentation at Functional Scala 2022, I've shown how to easily build beautiful command-line applications that your users will love. Using ZIO CLI, your command-line applications will support:

• All types of command-line parameters

• Perform both Pure and Impure validation

• Generate beautiful short and long documentation pages

• Support auto-correction plus auto-completion

Discover how you can have fun creating beautiful command-line apps that delight your users!
