The TeXlipse plugin adds LaTeX editing support to the Eclipse IDE. It provides both LaTeX and BibTeX editors, a project creation wizard, and a complete user manual of the editor functions. Additional features include syntax highlighting, document outline, section folding, command completion, cite and ref completion, templates, builder integration, viewer integration with inverse search, and more. The plugin makes it possible for LaTeX documents to be edited and built like normal projects in an IDE, and the viewer support makes it easy to check the outcome.
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.
JRequisite is an agile requirement management tool, which means your requirements are defined mainly via visual tools as opposed to textual requirement tools. Also, it is independent of the process used, so you may apply any process to your development. Despite being a requirement analysis and management tool, JRequisite tools are so general that they can be used in other areas of software development and even non-software related fields.
