Sigasi is an intelligent Eclipse- based development environment (IDE) for the VHDL language. It contains an ultra-fast VHDL parser and compiler that runs transparently in the background. At any given moment as you make modifications, the tool fully understands the design in terms of VHDL concepts. It allows you to write code faster by providing intelligent code completion, instant error reporting, intelligent navigation, mouse-over descriptions, a hierarchy browser, version control, issue and time tracking, and project and code templates.
protobuf-dt is Google’s Eclipse-based editor for protocol buffers. It provides all the features you’d expect from an Eclipse editor (syntax highlighting, outline view, content assist, etc.) plus some protocol buffer-specific features, such as "Open Declaration" (hyperlinking) support, including imported .proto files, configurable integration with protoc, and automatic removal of trailing whitespace.
Umple can be used for pure UML modeling. Or it can be used to add UML constructs, such as associations and state machines to code written in Java, PHP, or Ruby. It generates code in these languages that can save a large amount of programming effort and result in higher quality. The UmpleOnline tool allows you to edit UML diagrams graphically, and watch the Umple textual code being written in real time. This works the other way too: you can write textual Umple and watch the corresponding UML diagram appear. Umple is being extended to support patterns, tracing, and a variety of other features. Umple is written in itself, which is central to maintaining its quality. Umple can be used today by any programmer or modeler.
Sculptor is a productivity tool that applies the concepts from Domain-Driven Design and Domain Specific Languages. You express your design intent in a textual specification, from which Sculptor generates high quality Java code and configuration. You can use the concepts from Domain-Driven Design (DDD) in the textual Domain Specific Language (DSL), e.g. Service, Module, Entity, Value Object, Repository. The generated code is based on well-known frameworks such as Spring Framework, Hibernate, and Java EE. Sculptor takes care of the technical details and the tedious repetitive work, and lets you focus on delivering more business value (and have more fun). The DSL and the code generation drives the development and is not a one time shot. The application can be developed incrementally with an efficient round trip loop. Sculptor is useful when developing typical enterprise or Web applications that benefit from a rich and persistent domain model.
