Programs written in statically-typed languages are commonly extended with scripting engines that manipulate objects in the compiled layer. These scripting environments extend the capabilities of the program, at the cost of additional errors that would be caught by compile-time type checking. This paper describes a system for using type information from the compiled, statically-typed layer to pe...

This paper discusses how a CASE-tool supporting the Unified Modeling Language (UML) can be customized and extended using a visual scripting mechanism. We briefly introduce a set of UML model operations that can be used to transform a UML diagram of one type to another, and to perform set-theoretical operations on them. We discuss a visual scripting mechanism that can be used to combine these op...

Web application (WA) expands its usages to provide more and more services and it has become one of the most essential communication channels between service providers and the users. To augment the users’ experience many web applications are using client side scripting languages such as JavaScript but this growing of JavaScript is increasing serious security vulnerabilities in web application to...

In action game programming, programmers have to control multiple concurrent activities on the screen corresponding to multiple game characters. To address this difficulty, many game-oriented scripting languages have been proposed so far. However, current scripting languages seem to lack support for interactions among multiple concurrent activities in a state-dependent manner. To overcome this p...

Scripting languages are designed for glueing software components together. Such languages provide features like dynamic extensibility and dynamic typing with automatic conversion that make them well suited for rapid application development. Although these features entail runtime penalties, modern CPUs are fast enough to execute even large applications in scripting languages eeciently. Large app...

Published by the IEEE Computer Society 0018-9162/09/$26.00 © 2009 IEEE existing codes. In parallel scripting, users apply parallel composition constructs to existing sequential or parallel programs. With such methods, programmers can quickly specify highly parallel applications that may, depending on problem scale, require for their execution a 16-core workstation, a 16,000-core cluster, or a 1...

Many web applications use a mixture of HTML and scripting language code as the front-end to business services. Analogously to traditional applications, redundant code is introduced by copy-and-paste practices. Code duplication is a pathological form of software reuse because of its effects on the maintenance of large software systems. This paper describes how a simple semi-automated approach ca...

While conducting a security analysis of JavaScript and VBScript, the most popular scripting languages on the Web, we found some serious aws. Motivated by this outcome, we propose steps towards a sound de nition and design of a security framework for scripting languages on the Web. We show that if such a security framework had been integrated into the respective scripting languages from the very...

Successful tools require extensibility by the end-user. This is true for database systems as well which has led to user defined types, procedures as attributes, or close coupling of the database system to an object-oriented language. Here, we extend an object-relational DBMS with a scripting ability where the scripting commands closely follow the interaction modes and have a direct visualizatio...

Jacl, Java Command Language, is a version of the Tcl [1] scripting language for the Java [2] environment. Jacl is designed to be a universal scripting language for Java: the Jacl interpreter is written completely in Java and can run on any Java Virtual Machine. Jacl can be used to create Web content or to control Java applications. This paper explains the need for Jacl as a scripting language f...
