<p>Epsilon is a family of Java-based scripting languages for automating common model-based software engineering tasks, such as <a href="doc/egl">code generation</a>, <a href="doc/etl">model-to-model transformation</a> and <a href="doc/evl">model validation</a>, that work out of the box with EMF (including <a href="https://www.eclipse.org/Xtext">Xtext</a> and <a href="https://www.eclipse.org/sirius">Sirius</a>), UML, Simulink, XML and <a href="doc/emc">other types of models</a>. Epsilon also includes Eclipse-based editors and debuggers, convenient reflective tools for <a href="doc/flexmi">textual modelling</a> and <a href="doc/picto">model visualisation</a>, and <a href="doc/workflow">Apache Ant</a> tasks.</p>

<p class="admonition-title">Online Playground</p>
<p>If you prefer not to download/install anything just quite yet, you can fiddle with EMF models and metamodels, and with some of the Epsilon languages in the online <a href="live">Epsilon Playground</a>.</p>
</div>
<h2 id="installation">Installation<a class="headerlink" href="#installation" title="Permanent link">&para;</a></h2>
<p>Download the <a href="https://wiki.eclipse.org/Eclipse_Installer">Eclipse Installer</a> and select Epsilon, as shown below. Note that you will need a Java Runtime Environment installed on your system. More options for downloading Epsilon (update sites, Maven) are <a href="download">available here</a>.</p>

<h2 id="why-epsilon">Why Epsilon?<a class="headerlink" href="#why-epsilon" title="Permanent link">&para;</a></h2>
<ul>
<li><strong>One syntax to rule them all:</strong> All languages in Epsilon build on top of a <a href="doc/eol">common expression language</a> which means that you can reuse code across your model-to-model transformations, code generators, validation constraints etc.</li>
<li><strong>Integrated development tools:</strong> All languages in Epsilon are supported by editors providing syntax and error highlighting, code templates, and graphical tools for configuring, running, debugging and profiling Epsilon programs. </li>
<li><strong>Documentation, Documentation, Documentation:</strong> More than <a href="doc/articles">60 articles</a>, <a href="doc/screencasts">15 screencasts</a> and <a href="doc/examples">40 examples</a> are available to help you get from novice to expert.</li>
<li><strong>Strong support for EMF:</strong> Epsilon supports all flavours of EMF, including reflective, generated and non-XMI (textual) models such as these specified using Xtext or EMFText-based DSLs.</li>
<li><strong>No EMF? No problem:</strong> While Epsilon provides strong support for EMF, it is not bound to EMF at all. In fact, support for EMF is implemented as a driver for the model connectivity layer of Epsilon. Other drivers provide support for XML, CSV, Simulink and you can even roll out your own driver!</li>
<li><strong>No Eclipse? No problem either:</strong> While Epsilon provides strong support for Eclipse, we also provide <a href="download/#maven">standalone JARs through Maven Central</a> that you can use to <a href="doc/articles/run-epsilon-from-java">embed Epsilon in your plain Java</a> or Android application.</li>
<li><strong>Mix and match:</strong> Epsilon poses no constraints on the number/type of models you can use in the same program. For example, you can write a transformation that transforms an XML-based and an EMF-based model into a Simulink model and also modifies the source EMF model.</li>
<li><strong>Plumbing included:</strong> You can use the <a href="doc/workflow">ANT Epsilon tasks</a> to compose Epsilon programs into complex workflows. Programs executed in the same workflow can share models and even pass parameters to each other.</li>
<li><strong>Extensible:</strong> Almost every aspect of Epsilon is extensible. You can add support for your <a href="doc/articles/developing-a-new-emc-driver">own type of models</a>, extend the Eclipse-based development tools, add a new method to the String type, or even implement <a href="doc/articles/developing-a-new-language">your own model management language</a> on top of EOL.</li>
<li><strong>Java is your friend:</strong> You can call methods of Java classes from all Epsilon programs to reuse code you have already written or to perform tasks that Epsilon languages do not support natively.</li>
<li><strong>Parallel execution:</strong> Since 2.0, Epsilon is multi-threaded, which includes first-order operations and some of the rule-based languages, making it faster than other interpreted tools.</li>
<li><strong>All questions answered:</strong> The <a href="forum">Epsilon forum</a> contains more than 9,500 posts and we're proud that no question has ever gone unanswered.</li>
<li><strong>We're working on it:</strong> Epsilon has been an Eclipse project since 2006 and it's not going away any time soon.</li>
