|
|
<p>In addition to providing runnable code playgrounds, mdBook optionally allows them
|
|
to be editable. In order to enable editable code blocks, the following needs to
|
|
be added to the <em><strong>book.toml</strong></em>:</p>
|
|
<pre><code class="language-toml">[output.html.playground]
|
|
editable = true
|
|
</code></pre>
|
|
<p>To make a specific block available for editing, the attribute <code>editable</code> needs
|
|
to be added to it:</p>
|
|
<pre><code class="language-markdown">```rust,editable
|
|
fn main() {
|
|
let number = 5;
|
|
print!("{}", number);
|
|
}
|
|
```
|
|
</code></pre>
|
|
<p>The above will result in this editable playground:</p>
|
|
<pre><pre class="playground"><code class="language-rust editable edition2018">fn main() {
|
|
let number = 5;
|
|
print!("{}", number);
|
|
}</code></pre></pre>
|
|
<p>Note the new <code>Undo Changes</code> button in the editable playgrounds.</p>
|
|
<h2 id="customizing-the-editor"><a class="header" href="#customizing-the-editor">Customizing the Editor</a></h2>
|
|
<p>By default, the editor is the <a href="https://ace.c9.io/">Ace</a> editor, but, if desired,
|
|
the functionality may be overridden by providing a different folder:</p>
|
|
<pre><code class="language-toml">[output.html.playground]
|
|
editable = true
|
|
editor = "/path/to/editor"
|
|
</code></pre>
|
|
<p>Note that for the editor changes to function correctly, the <code>book.js</code> inside of
|
|
the <code>theme</code> folder will need to be overridden as it has some couplings with the
|
|
default Ace editor.</p>
