MetaMod is a minimalistic language workbench built in Jetbrains MPS.

1. Jetbrains MPS 3.2.1 release April 10, 2015
   • Go to https://github.com/JetBrains/MPS/releases/tag/3.2.1, download and build this version.
2. mbeddr 1.0 RC1
   • Get com.mbeddr.allInOne.zip from https://github.com/mbeddr/mbeddr.core/releases/tag/1.0-RC1, unzip it, and place its contents into the plugins directory of your MPS installation.

After opening MetaMod in MPS, there are a few steps to the compilation of MetaMod because there are circular dependencies in the project.

1. Select all languages in the project (folders marked with L), plus the solution named RuntimeClassses, right-click and select Make Selected Modules.
   • At this point, you will have some compilation errors.
2. Select all languages in the project that still have (generation required) to their right, right-click and select Make Selected Modules.
3. Repeat step 2 until no language has (generation required) to its right.
4. Reopen MPS.

For a simple example to play with, you can go to solution CaseStudies/Courses/OOTICourseShapes. To get a better understanding of MetaMod, you can extend the shapes language with new shapes; for instance, try adding triangles to the canvas.
