<p>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 <code>Array[String]</code>, such applications lack features that users take for granted, including:</p>
<ul>
<li><p>Flexible subcommands</p>
</li>
<li><p>Options</p>
</li>
<li><p>Arguments</p>
</li>
<li><p>Validations</p>
</li>
<li><p>Documentation pages</p>
</li>
</ul>
<p>In this presentation at <a target="_blank" href="https://www.functionalscala.com/">Functional Scala 2022</a>, I've shown how to easily build beautiful command-line applications that your users will love. Using <a target="_blank" href="https://github.com/zio/zio-cli">ZIO CLI</a>, your command-line applications will support:</p>
<ul>
<li><p>All types of command-line parameters</p>
</li>
<li><p>Perform both <em>Pure</em> and <em>Impure</em> validation</p>
</li>
<li><p>Generate <em>beautiful</em> short and long documentation pages</p>
</li>
<li><p>Support <em>auto-correction</em> plus <em>auto-completion</em></p>
</li>
</ul>
<p>Discover how you can have fun creating beautiful command-line apps that delight your users!</p>
