Interesting tools for code reviews, development, and documentation - tools that aren't just the same-old, same-old. Tools that make you think.

Aspects Everywhere: Language Extensibility for JDT through Equinox Aspects

The recent proliferation of Java-like languages that run on the JVM is an indicator of the future direction of application development on the Java platform. However, Eclipse and JDT do not provide any support for integrating these kinds of languages with the Java model. For example there is no supported way to include Java-like elements in Java searches, Java type hierarchies, Java call hierarchies, etc.

This talk describes how we have used Equinox Aspects and load-time weaving on the AJDT project to provide a structured, flexible, and generic approach to extending the JDT for use with Java-like languages. We describe our JDT Weaving plugin, how its use has allowed the AJDT project to integrate deeply with JDT, and how other language developers can use this plugin to receive the same benefits.

JSONViewer and XPathUtility

AJAX and SOA developers use JSON daily and its very challenging to analyze complex JSONs. It always helps to have JSON in a hierarchical format as we often write JSON right from scratch or sometimes we want to analyze the JSON that comes out of a server response.The motivation for the JSON2XMLTreeViewer is to make developers of AJAX and SOA to visualize the JSON as XML and at the same time as TreeView.

For many Desktop and JEE projects its necessary to write and test the XPath expressions. With the integrated features of Eclipse as IDE, the XPathUtility plugin will enable developers to be able to write the XPath with the auto-complete feature and test the XPath for the results.

This short talk would give a brief description of these two plugins and a demo of how the plugins can be used. These plugins can be easily plugged into any of the AJAX and SOA IDEs so that developers can take advantage of the Eclipse as IDE.

ReviewClipse - Supporting Code-Reviews within the Eclipse IDE

Code reviews enhance software quality, so they should always be a part of our daily work. In our session we will present an ECLIPSE integrated code review plug-in, which helps developers to review the source code efficient on a per changeset basis - the item under inspection is one changeset in the revision control system.

The tight integration of the review plug-in into the ECLIPSE development environment helps the developer to accept the review task as his daily work, like debugging or re-factoring. Because of its simple design it's possible to initiate the review process on any existing project in a few minutes. All review data is stored within files, shared with the already configured subversion repository of your project. So there is no need to setup any server-side application, apart from the already existing subversion repository. The reviewer uses a special review editor to inspect the changesets, compares different versions of a file with the compare editor, and leaves his rating and optional comments for the commiter of the changeset. The review editor aligns with the basic concepts of the ECLIPSE environment, so the initial training will consume little time. Here are some features of the ECLIPSE plug-in:

An extended version of the review plugin, based on the ECLIPSE Collaboration Framework, further provides notifications, e.g. about new review comments.

The Vienna University of Technology uses this review plug-in for many software development projects. The flexible design allows to use different types of review models, whichever fits best into your software engineering process. The assignments may be done in a peer to peer manner, where the developers inspect the code changes of one or more team members. Reading each others code has the consequence, that developers also learn the code from their colleagues, thus supporting collective code ownership. As a result, a better code sharing and reuse will be more likely, the team's interaction and creativity will be encouraged. A more hierarchical approach would be to assign a senior developer to review the code for new or less experienced developers. The senior developer in the role of the reviewer may enforce coding standards and better code quality within the development team.

Because of our positive experience with the plug-in and the good feedback we have received, we will release the review plug-in under an open-source license prior to the EclipseCon 2009.
