We have developed two computer algebra systems, meditor [9] and JAS [12]. These CAS systems are available as Java libraries. For the use-case of interactively entering and manipulating mathematical expressions, there is a need of a scripting front-end for our libraries. Most other CAS invent and implement their own scripting interface for this purpose. We, however, do not want to reinvent the w...

Domain-Independent Models are mainly used for documentation purposes and are most of the time too complex to be directly executed, even by code generation. Domain-Specific Models can sometimes be executed, but their scope is too specific to be reused for other purposes. We propose to develop a mechanism that allows the creation of modeling languages that will be directly executed into software ...

Since 2002, over half of reported cyber vulnerabilities are caused by input validation vulnerabilities . Over 50 % of input validation vulnerabilities were cross-site scripting and SQL injection vulnerabilities in 2006, based on the (US) National Vulnerability Database. Techniques to mitigate cross-site scripting and SQL injection vulnerabilities have been proposed. However, applying those tech...

This paper discusses an approach to scripting in open hypermedia systems. The approach is based on an embedded interpreter that enables scripts to communicate with the hypermedia engine as well as external applications in an open way. The design and implementation of the scripting facilities in the Webvise open hypermedia system exemplify this approach. In Webvise, scripting is closely connecte...

The Open Scripting Architecture combines aspects of object-oriented programming, distributed computation, database queries, and dynamic languages into a powerful and practical system for automation, integration, and customization of applications and system services. Applications are integrated together with distributed messaging. The messages operate upon user-level application objects, like wi...

This report documents the program and the outcomes of Dagstuhl Seminar 12011 on the “Foundations for Scripting Languages”. The choice of “for” rather than “of” is intentional: it is our thesis that scripting languages are in need of foundations to support their extensive use but lack them, and we hope this event consolidated and advanced the state of the art in this direction. Seminar 02.–06. J...

Any file is fundamentally a binary data stream. A practical solution was achieved to interpret binary data stream. A new scripting language named Data Format Scripting Language (DFSL) was developed to describe the physical layout of the data in a structural, more intelligible way. On the basis of the solution, a generic software application was implemented; it parses various binary data streams...
