Abstract or Description
Recent advances in programming environments have focused on improving programmer productivity by utilizing the inherent structure in computer programs. However, because these environments represent code as plain text, it is difficult and sometimes impossible to embed interactive tools, annotations, and alternative views in the code itself. Barista is an implementation framework that enables the creation of such user interfaces by simplifying the implementation of editors that represent code internally as an abstract syntax tree and maintain a corresponding, fully structured visual representation on-screen. Barista also provides designers of editors with a standard text-editing interaction technique that closely mimics that of conventional text editors, overcoming a central usability issue of previous structured code editors.
