JInto is a plugin for Eclipse that lets the developer easily edit and maintain resource bundles (files that hold the localized strings for an application). It features parallel editing of all language versions (side by side), warnings when no text has been provided for a specific key, or when the text for one key is identical for different languages, and a search wizard to locate unused strings (strings that are referenced, but not actually defined in the resource bundle). It has been tested under Windows and Linux.
Style is the ongoing C++ port of IBM's SWT for Java, itself deriving from IBM's VisualAge for SmallTalk, with two major twists. First, it is written in 100% ISO-C++ with no specific compiler dependencies, and second, it comes with a threading model design that guarantee that users won't be stuck with busy cursors forever. It currently targets OS X, Win32, and GTK.
The Eclipe Eiffel Development Tools (EDT) are a set of plugins which implement a full-fledged, highly integrated Eiffel development environment based on the Eclipse Platform. The EDT plugins contribute a number of facilities specific to Eiffel, such as an Eiffel builder, a Cluster Explorer, and Refactorings.
The Generic Eclipse Modeling System (GEMS) is a MDD tool for Eclipse that allows for the rapid development of visual modeling tools for Eclipse based on EMF/GEF. Developers specify the rules for a domain language using a metamodel and the tool generates a diagram editor plugin that enforces the rules from the metamodel. Interpreters can then be written to traverse the model and generate code, perform analyses, or execute the model. The tool supports complex model analysis using Prolog; Java, OCL, and Prolog constraints, remote model updating via CORBA, applying CSS styles to models, model-to-model linking, exportable templates, and more.
Pieces of Flare is an Eclipse Plugin which allows (J2EE) developers to synchronize source directories within their project to deployment directories on the AppServer. This plugin is written to allow automatic deployment of JSP files whenever they are saved, but it can be used for any file type.
TRex is a tool to help maintain test suites written in the standardized Testing and Test Control Notation (TTCN-3). It provides IDE functionality for the TTCN-3 core notation and supports the assessment and automatic restructuring of TTCN-3 test suites by providing suitable metrics and refactorings.
