Just wanted to let you know that Beta version of JetBrains MPS, our implementation of Language Oriented Programming paradigm, has just been released.
MPS is an environment for software developers to create new custom languages, extend existing languages, and use them to develop software. MPS is also an instrument for creating Domain Specific Languages (DSLs). Domain experts not familiar with programming can use MPS to work with the DSLs created there.
MPS is the second product we release that is built on IntelliJ platform. The first was RubyMine, our new Ruby IDE.
MPS will be free for all users and, moreover, a major part of its code will be open-source.
You are welcome to download MPS, try it and submit your feedback to .
