<h2>Overview</h2>

<p>Today, the Groovy-Eclipse team has released milestone 2 of Groovy-Eclipse, tool support for the <a href="http://groovy.codehaus.org">Groovy</a> programming language built in <a href="http://eclipse.org">Eclipse</a>.  In this milestone release, we have focused on responsiveness and features in the user interface.  This milestone is significantly more stable than milestone 1 as we have <a class="confluence-link" href="#issuesfixed" data-anchor="issuesfixed" data-linked-resource-default-alias="issuesfixed" data-base-url="http://docs.codehaus.org">fixed over 100 issues</a> in the bug tracker.</p>

<h2>Inferencing Engine</h2>

<p>The <a href="http://contraptionsforprogramming.blogspot.com/2009/11/how-type-inferencing-for-groovy-in.html">inferencing engine</a> now forms the core of many of Groovy-Eclipse's most prominent features.  The inferencing engine is uses static analysis to infer the type of a single or a group of expressions of Groovy code.  it is being used as the basis for content assist, navigation, search, and discovering unknown references.  We have posted a <a href="http://contraptionsforprogramming.blogspot.com/2009/11/how-type-inferencing-for-groovy-in.html">detailed description</a> of the inferencing engine.</p>

<h2>Refactoring Support</h2>

<p><a href="http://contraptionsforprogramming.blogspot.com/2009/11/new-cross-language-refactoring-support.html">Cross-language refactoring support</a> is now available in Groovy-Eclipse.  Now, when renaming Java methods, fields, and classes, your Groovy code will be updated as well.  And the reverse is true.  You can find more information <a href="http://contraptionsforprogramming.blogspot.com/2009/11/new-cross-language-refactoring-support.html">here</a>.</p>

<p>The Groovy compiler now parses task tags such as <code>TODO</code>, <code>FIXME</code>, and <code>XXX</code>.  They are treated by Eclipse in the same way that Java task tags are.  Task tags are configurable and can be viewed in the <em>Tasks</em> view.  More detailed information can be found <a href="http://andrewclement.blogspot.com/2009/12/groovy-eclipse-task-tags.html">here</a>.</p>

<h2>Content Assist and Navigation in GStrings</h2>

<p>Content assist and navigation are now supported inside of GStrings.  For example, in the following image, content assist will display both local variables:<br />
<img class="confluence-embedded-image confluence-content-image-border image-center" src="/download/attachments/231082325/gstring_contentassist.gif?version=1&amp;modificationDate=1371635474438" data-image-src="/download/attachments/231082325/gstring_contentassist.gif?version=1&amp;modificationDate=1371635474438" data-linked-resource-id="231377093" data-linked-resource-type="attachment" data-linked-resource-default-alias="gstring_contentassist.gif" data-base-url="http://docs.codehaus.org" data-linked-resource-container-id="231082325" title="null > gstring_contentassist.gif"></p>

<p>Notice also that the <code>x</code> is underlined.  This is because the <code>x</code> reference is undefined in the current scope.  See the description of the <a href="http://contraptionsforprogramming.blogspot.com/2009/11/how-type-inferencing-for-groovy-in.html">inferencing engine</a> for more information on this.</p>

<h2>Extensibility for custom DSLs</h2>

<p>Also included in M2 are extension points for custom DSLs to hook into Groovy-Eclipse's inferencing engine, content assist, and syntax highlighting.  This is still basic work and will be more fully announced for RC1.  This extensibility is particularly suited for implementing <a href="http://grails.org">Grails</a> <a href="http://www.grails.org/STS+Integration">tool support in STS</a>, but it is generic enough for any Groovy DSL to use.</p>
