A library for Spotting Cross Language Relations in Polyglot Frameworks

Nowadays, most of the web frameworks are developed using dierent programming languages, both for server and client side programmes. The typical scenario includes a general purpose language (e.g. Ruby, Python, Java) used together with dierent specialized languages: HTML, CSS, Javascript and SQL. All the artifacts are connected via different types of relations, most of which depend on the adopted framework. These cross-language relations are normally not captured by tools which require the developer to learn and to remember those associations in order to understand and maintain the application. This paper describes a library for detecting cross-language relations in polyglot frameworks. The library has been developed to be modular and to be easily integrated in existing IDEs. The library is publicly available at http://github.com/CrossLanguageProject/crosslanguagespotter.
