<h2 id="inline-code">Inline code</h2>

<p>Inline code with <code>.cb.run</code> gives raw stdout.</p>

</div>

</div>

<h3 id="expression-and-inline-notebook">Expression and inline notebook</h3>

<p>Inline code with <code>.cb.expr</code> evaluates an expression and then inserts the raw output into the document, where it is interpreted as Markdown. Inline code with <code>.cb.nb</code> (<code>nb</code> is short for <code>notebook</code>) is similar, except output is shown verbatim. Expressions are evaluated via <code>$(<expr>)</code>.</p>

</div>

</div>

</div>

</div>

<h3 id="stderr">Stderr</h3>

<p>In the event of an error, inline code automatically shows stderr by default. This code is executed in its own session, <code>inline_error</code>, so that it does not impact other examples.</p>

<pre><code>`echooo $((1 + 2))`{.bash .cb.run session=inline_error}</code></pre>

</div>

<p><code class="stderr"><string>: line 1: echooo: command not found</code></p>

</div>

<h2 id="block-code">Block code</h2>

<p>Code blocks with <code>.cb.run</code> give raw stdout. There is continuity between code blocks so long as they are in the same session; variables persist.</p>

<pre><code>```{.bash .cb.run}

message="Hello from *Bash!*"

```</code></pre>

</div>

<pre><code>```{.bash .cb.run}

echo "$message"

```</code></pre>

</div>

<p>Hello from <em>Bash!</em></p>

</div>

<h3 id="notebook">Notebook</h3>

<p>Code blocks with <code>.cb.nb</code> show the code and also the verbatim stdout.</p>

<pre><code>```{.bash .cb.nb session=notebook}

ls | grep "bash"

```</code></pre>

</div>

<pre class="stdout"><code>bash.cbmd

bash.html

build_bash.sh</code></pre>

</div>

<pre><code>```{.bash .cb.nb session=notebook}

which python3 && which python

```</code></pre>

</div>

<div class="sourceCode" id="cb11" data-startFrom="2"><pre class="sourceCode numberSource bash numberLines"><code class="sourceCode bash" style="counter-reset: source-line 1;"><span id="cb11-2"><a href="#cb11-2"></a><span class="fu">which</span> python3 <span class="kw">&&</span> <span class="fu">which</span> python</span></code></pre></div>

<pre class="stdout"><code>/usr/bin/python3</code></pre>

</div>

<h3 id="stderr-1">Stderr</h3>

<p>Code blocks show stderr automatically by default.</p>

<pre><code>```{.bash .cb.nb session=block_error}

set -u

var="$((1 + 2))"

echo "$varrr"

```</code></pre>

</div>

<span id="cb14-3"><a href="#cb14-3"></a><span class="bu">echo</span> <span class="st">"</span><span class="va">$varrr</span><span class="st">"</span></span></code></pre></div>
