The project includes the necessary code to integrate any language server (conforming to the Language Server Protocol specification) or Debug Adapter (conforming to the Debug Adapter Protocol) in the Eclipse IDE: it orchestrates the requests to the language servers or debug adapters and presents the response in the usual IDE metaphors so users can manipulate them. The default integration is to provide features into the Platform's Generic and Extensible editor, but some code may be used as API to let integration be done with other Eclipse-based editors. It's build on top of Eclipse LSP4J.
Eclipse Papyrus-xtUML is a tool which supplies the capability to edit, execute and translate xtUML models. Executable, translatable UML (xtUML) is an extension to UML based upon the Shlaer-Mellor Method of Model-Driven Architecture (MDA), which supports a powerful approach to Model-Driven Development (MDD). Papyrus-xtUML provides the system design community with access to xtUML editing, execution and translation capabilities, along with a forum to advance the use of this methodology.
Eclipse Golo is a dynamically-typed programming language for the Java Virtual Machine. Golo is largely interoperable with Java and other JVM languages (e.g., numeric types are boxing classes from java.lang, and collection literals leverage java.util classes). Golo supports imperative and functional programming patterns. Golo is not a strictly object-oriented programming language: it very much resembles Go in the sense that methods are just functions applied to specific receiver types. Golo or Java defined types can be augmented in Golo, that is, new methods can be made available.
