Mixing Programming Languages

story imageMost programming languages come with built in support for handling common data types, however using and manipulating user-defined data types has to be done via general purpose syntax. This often leads to using Strings rather than structured data. Computer scientists have designed safe way to use multiple programming languages within the same program, which will allow programmers to use the language most suitable for each function while also guarding against code injection. Their language, called Wyvern, is available as an Open Source Project.

The full paper is available as a PDF.
Wyvern determines which sublanguage is being used within the program based on the type of data the programmer is manipulating. Types specify the format of data, such as alphanumeric characters, floating-point numbers or more complex data structures, such as Web pages and database queries.

...

Many programming tasks can involve multiple languages; when building a Web page, for instance, HTML might be used to create the bulk of the page, but the programmer might also include SQL to access databases and JavaScript to allow for user interaction. By using type-specific languages, Wyvern can simplify that task for the programmer, Aldrich said, while also avoiding workarounds that can introduce security vulnerabilities.
