FLAPIE (FLuent API Editor) is an Eclipse plugin, which will help you create an internal DSL in Java. It is based on the Eclipse Xtext project, which will provide an editor in form of Eclipse plugin and a DSL for creating internal DSLs or fluent APIs for Java using code generation. The aim of this project is to collect all the patterns for internal DSLs applicable to Java and come with some new ones and create a DSL of them. FLAPIE will enable Java developers who cannot use external DSLs in their working enviroment to experience advantages of DSLs and/or to create easily fluent APIs for their frameworks and libraries.
