mps-UMLRT

Model ROOM/UML-RT systems in JetBrains MPS and generate C++ for the Papyrus-RT runtime. The executable subset supports static capsule composition, payload-free protocols, hierarchical states and C++ effects/guards. This is not a complete UML-RT implementation or a claim of strict MARTE conformance.

Get started

Use JDK 25 and MPS 2026.1.1. On Windows:

.\gradlew.bat setup generateLibrariesXml
.\gradlew.bat --no-daemon --console=plain --continue check verifyPapyrusPingPong

Native tests require Visual Studio C++ build tools and CMake. See build and run for requirements, examples and troubleshooting. On Linux use ./gradlew; see the build guide for native toolchain selection.
