<h1 class="heading">Pygments</h1>
<h2 class="subheading">Use Pygments in Java</h2>
<a id="backlink" href="index.html">&laquo; Back To Index</a>
<p>Thanks to <a class="reference external" href="http://www.jython.org">Jython</a> it is possible to use Pygments in
Java.</p>
<p>This page is a simple tutorial to get an idea of how this is working. You can
then look at the <a class="reference external" href="http://www.jython.org/docs/">Jython documentation</a> for more
advanced use.</p>
<p>Since version 1.5, Pygments is deployed on <a class="reference external" href="http://repo1.maven.org/maven2/org/pygments/pygments/">Maven Central</a> as a JAR so is Jython
which makes it a lot easier to create the Java project.</p>
<p>Here is an example of a <a class="reference external" href="http://www.maven.org">Maven</a> <tt class="docutils literal">pom.xml</tt> file for a
project running Pygments:</p>
<div class="syntax"><pre><span class="cp">&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;</span>
<span class="nt">&lt;project</span> <span class="na">xmlns=</span><span class="s">&quot;http://maven.apache.org/POM/4.0.0&quot;</span>
<span class="na">xmlns:xsi=</span><span class="s">&quot;http://www.w3.org/2001/XMLSchema-instance&quot;</span>
<span class="na">xsi:schemaLocation=</span><span class="s">&quot;http://maven.apache.org/POM/4.0.0</span>
<span class="s"> http://maven.apache.org/maven-v4_0_0.xsd&quot;</span><span class="nt">&gt;</span>
<span class="nt">&lt;modelVersion&gt;</span>4.0.0<span class="nt">&lt;/modelVersion&gt;</span>
<span class="nt">&lt;groupId&gt;</span>example<span class="nt">&lt;/groupId&gt;</span>
<span class="nt">&lt;artifactId&gt;</span>example<span class="nt">&lt;/artifactId&gt;</span>
<span class="nt">&lt;version&gt;</span>1.0-SNAPSHOT<span class="nt">&lt;/version&gt;</span>
<span class="nt">&lt;dependencies&gt;</span>
<span class="nt">&lt;dependency&gt;</span>
<span class="nt">&lt;groupId&gt;</span>org.python<span class="nt">&lt;/groupId&gt;</span>
<span class="nt">&lt;artifactId&gt;</span>jython-standalone<span class="nt">&lt;/artifactId&gt;</span>
<span class="nt">&lt;version&gt;</span>2.5.3<span class="nt">&lt;/version&gt;</span>
<span class="nt">&lt;/dependency&gt;</span>
<span class="nt">&lt;dependency&gt;</span>
<span class="nt">&lt;groupId&gt;</span>org.pygments<span class="nt">&lt;/groupId&gt;</span>
<span class="nt">&lt;artifactId&gt;</span>pygments<span class="nt">&lt;/artifactId&gt;</span>
<span class="nt">&lt;version&gt;</span>1.5<span class="nt">&lt;/version&gt;</span>
<span class="nt">&lt;scope&gt;</span>runtime<span class="nt">&lt;/scope&gt;</span>
<span class="nt">&lt;/dependency&gt;</span>
<span class="nt">&lt;/dependencies&gt;</span>
<span class="nt">&lt;/project&gt;</span>
</pre></div>
<p>The following Java example:</p>
<div class="syntax"><pre><span class="n">PythonInterpreter</span> <span class="n">interpreter</span> <span class="o">=</span> <span class="k">new</span> <span class="n">PythonInterpreter</span><span class="o">();</span>
<span class="c1">// Set a variable with the content you want to work with</span>
<span class="n">interpreter</span><span class="o">.</span><span class="na">set</span><span class="o">(</span><span class="s">&quot;code&quot;</span><span class="o">,</span> <span class="n">code</span><span class="o">);</span>
<span class="c1">// Simple use Pygments as you would in Python</span>
<span class="n">interpreter</span><span class="o">.</span><span class="na">exec</span><span class="o">(</span><span class="s">&quot;from pygments import highlight\n&quot;</span>
<span class="o">+</span> <span class="s">&quot;from pygments.lexers import PythonLexer\n&quot;</span>
<span class="o">+</span> <span class="s">&quot;from pygments.formatters import HtmlFormatter\n&quot;</span>
<span class="o">+</span> <span class="s">&quot;\nresult = highlight(code, PythonLexer(), HtmlFormatter())&quot;</span><span class="o">);</span>
<span class="c1">// Get the result that has been set in a variable</span>
<span class="n">System</span><span class="o">.</span><span class="na">out</span><span class="o">.</span><span class="na">println</span><span class="o">(</span><span class="n">interpreter</span><span class="o">.</span><span class="na">get</span><span class="o">(</span><span class="s">&quot;result&quot;</span><span class="o">,</span> <span class="n">String</span><span class="o">.</span><span class="na">class</span><span class="o">));</span>
</pre></div>
<p>will print something like:</p>
<div class="syntax"><pre><span class="nt">&lt;div</span> <span class="na">class=</span><span class="s">&quot;highlight&quot;</span><span class="nt">&gt;</span>
<span class="nt">&lt;pre&gt;&lt;span</span> <span class="na">class=</span><span class="s">&quot;k&quot;</span><span class="nt">&gt;</span>print<span class="nt">&lt;/span&gt;</span> <span class="nt">&lt;span</span> <span class="na">class=</span><span class="s">&quot;s&quot;</span><span class="nt">&gt;</span><span class="ni">&amp;quot;</span>Hello World<span class="ni">&amp;quot;</span><span class="nt">&lt;/span&gt;&lt;/pre&gt;</span>
<span class="nt">&lt;/div&gt;</span>
</pre></div>
