JetBrains MPS is a metaprogramming system which is being developed by JetBrains. It implements language-oriented programming. MPS is an environment for language definition, a language workbench, and integrated development environment (IDE) for such languages.
Developers from different domains can benefit from domain specific language extensions in general purpose programming languages. For example, Java developers working with financial applications might benefit from built-in support of monetary values. Unfortunately, traditional text based languages are subject to text ambiguity problems which makes such extensions problematic.
MPS supports composable language definitions. This means that languages can be extended, and embedded, and these extensions can be used, and will work, in the same program in MPS. For example, if Java is extended with a better syntax for collections and then again extended with a better syntax for dates, these extensions will work well together.
MPS solves grammar ambiguity issues by working with the abstract syntax tree directly. In order to edit such a tree, a text-like projectional editor is used.
MPS provides a reusable language infrastructure which is configured with language definition languages. MPS also provides many IDE services automatically: editor, , find usages, etc.
mbeddr is an embedded development system based on MPS. It has languages tailored to embedded development and formal methods:
In October 2009, JetBrains released the YouTrack bug tracking system - the first commercial software product developed with MPS.
In April 2010, the Realaxy ActionScript Editor beta was released, the first commercial IDE based on the MPS platform.
The MPS source code is released under the Apache License.
