<p><img src="images/navigation-arrow-keys.png" alt="Navigate with arrow keys"></p>
<h3 id="evaluating-clojure">Evaluating Clojure</h3>
<p>Code can be written directly in the pages of this workshop.  The code boxes below allow you to edit the code in the top of the box, with the results evaluated automatically and updated in the results in the bottom of the box.</p>
<pre><code class="lang-eval-clojure">(defn live-evaluation [opinion]
  (str &quot;Clojure live evaluation is... &quot; opinion))

(live-evaluation &quot;awesomenessness&quot;)
</code></pre>
<h3 id="exercises">Exercises</h3>
<p>Exercises are denoted by using the Note <a href="https://www.npmjs.com/package/gitbook-plugin-callouts" target="_blank">callout plugin</a> for gitbook.  Exercises look like:</p>
<div class="panel panel-primary"><div class="panel-heading"><h3 class="panel-title" id="create-a-clojure-project"><i class="fa fa-edit"></i> Create a Clojure project</h3></div><div class="panel-body"><p>Use the Leiningen tool to create a project called <strong>clojure-is-awesomenessness</strong></p></div></div>
<h3 id="answers">Answers</h3>
<p>Suggested answers are included directly in the workshop in hidden sections.  To get the most out of the workshop you should try to solve the answers first and try several alternative approaches to solving each exercise.</p>
<p>An example of an answer in a hidden section is as follows:</p>
<sec data-title="Suggested answer. Press the button to reveal" data-id="answer001" data-collapse="true"><div class="panel panel-default"><div class="panel-heading"><b>Suggested answer. Press the button to reveal<a class="pull-right section atTitle btn btn-default" target="answer001"><span class="fa fa-angle-up"></span></a></b></div><div class="panel-collapse in" id="answer001"><div class="panel-body">
<pre><code class="lang-clj">(defn who-has-the-answer [name])
  (str &quot;Only &quot; name &quot; have the answers, allegedly&quot;))

(who-has-the-answers &quot;Smarties&quot;)
</code></pre>
<p>Cultural reference to an <a href="https://www.youtube.com/watch?v=UA5aLfM9N0E" target="_blank">award winning TV advertisement</a> in 1984 that was created using computer graphics.</p>
<p>We do not endorse smarties or suggest that anyone has all the answers :)</p>
