Domain-specific languages implemented with Xtext have proven to be powerful in many areas ranging from requirements specifications to programming languages. One key factor to success is the textual representation of the model which eases creation, maintainance and especially merging. Nevertheless, at some point a graphical representation simplifies the communication by giving a broader overview of the modeled elements.
EMF Parsley is a GUI renderer built on top of EMF that allows developers to quickly develop User Interfaces. The main goal of the Project is to provide an easy way to build complex applications, hiding some boring details, with simple and powerful APIs. EMF Parsley in fact provides some built-in components like Trees, Tables and Forms that can be easily mashed up and customized.
