JetBrains MPS 1.0 Paints the Future of Software Development with a New Programming Paradigm

Implementing the Language Oriented Programming paradigm, JetBrains MPS provides unprecedented freedom in extending programming languages and creating DSLs for developing real-life applications.

July 23, 2009

Prague, Czech Republic, July 23, 2009 — JetBrains®, creators of intelligent and innovative productivity-enhancing tools for software developers, have announced the 1.0 release of their new conceptual software development environment — Meta Programming System, or MPS. 

MPS is a professional language workbench and integrated development environment (IDE) for extending existing languages and using them to develop software. It is also an advanced instrument for creating new custom languages, or Domain Specific Languages, and allows defining new environments for working with these DSLs. By using MPS, and DSLs created with its help, domain experts can solve their domain-specific tasks easily, even if they’re not familiar with programming.

To empower developers in adapting programming languages to their specific needs, MPS provides advanced facilities for defining language typesystems, constraints, specialized projectional editors and generators. Utilizing the generative approach, languages in MPS are described on a higher level, after which MPS generates compilable code in other languages, such as Java. A key advantage of MPS is that languages are composable: they can be easily combined with each other, which promotes reuse of languages.

“MPS has come a long way since the original concept back in 2003 and is now a powerful, mature software tool that paints the future of software development,” said Sergey Dmitriev, JetBrains CEO and author of the MPS concept. “We’ve always taken pride in using our own software products, and we’re already using MPS as a development platform for several of our latest products. One of them, a web-based issue tracker code-named Charisma, is already available for early access preview.”

MPS is free for all users, with a major part of its source code open and available under Apache license.
