Multilanguage Debugger Architecture

When debugging applications written in several programming languages, current; debuggers usually fail to provide programmers with the same quality of user experience that is common for single-language application debugging. As a result, development of multilanguage applications tends to be more expensive both in terms of development and maintenance costs. In this paper, we propose a flexible architecture that facilitates integration of multiple single-language debuggers into a single multilanguage debugger. In addition, we describe its proof-of-concept implementation that allows debugging of applications written in Smalltalk, XQuery and JavaScript.
