<p>You can build a text-based interface that will run in the terminal using Dioxus.</p>
<p><img src="https://github.com/DioxusLabs/rink/raw/master/examples/example.png" alt="Hello World screenshot" /></p>
<blockquote>
<p>Note: this book was written with HTML-based platforms in mind. You might be able to follow along with TUI, but you'll have to adapt a bit.</p>
</blockquote>
<h2 id="support"><a class="header" href="#support">Support</a></h2>
<p>TUI support is currently quite experimental. But, if you're willing to venture into the realm of the unknown, this guide will get you started.</p>
<ul>
<li>It uses flexbox for the layout</li>
<li>It only supports a subset of the attributes and elements</li>
<li>Regular widgets will not work in the tui render, but the tui renderer has its own widget components that start with a capital letter. See the <a href="https://github.com/DioxusLabs/dioxus/blob/master/packages/dioxus-tui/examples/widgets.rs">widgets example</a></li>
<li>1px is one character line height. Your regular CSS px does not translate</li>
<li>If your app panics, your terminal is wrecked. This will be fixed eventually</li>
</ul>
<h2 id="getting-set-up"><a class="header" href="#getting-set-up">Getting Set up</a></h2>
<p>Start by making a new package and adding Dioxus and the TUI renderer as dependancies.</p>
<pre><code class="language-shell">cargo new --bin demo
cd demo
cargo add dioxus
cargo add dioxus-tui
</code></pre>
<p>Then, edit your <code>main.rs</code> with the basic template.</p>
<pre><pre class="playground"><code class="language-rust edition2018">#![allow(non_snake_case)]
// import the prelude to get access to the `rsx!` macro and the `Scope` and `Element` types
use dioxus::prelude::*;

fn main() {
    // launch the app in the terminal
    dioxus_tui::launch(App);
}

// create a component that renders a div with the text &quot;Hello, world!&quot;
fn App(cx: Scope) -&gt; Element {
    cx.render(rsx! {
        div {
            &quot;Hello, world!&quot;
        }
    })
}
</code></pre></pre>
<p>To run our app:</p>
<pre><code class="language-shell">cargo run
</code></pre>
<p>Press &quot;ctrl-c&quot; to close the app. To switch from &quot;ctrl-c&quot; to just &quot;q&quot; to quit you can launch the app with a configuration to disable the default quit and use the root TuiContext to quit on your own.</p>
