JetBrains MPS is an open-source meta-programming system (language workbench) for designing domain-specific languages with a complete development environment. It provides a projectional editor with completion, semantics, and type checking out of the box, plus generators that compile DSLs into target languages such as Java, C, and XML.
Use cases
- create a domain-specific language for my field
- build a DSL with editor completion and type checking
- projectional editor supporting math notation, diagrams, and forms
- generate Java, C, or XML code from a custom language
- language workbench for language engineering
- define a non-textual DSL with full IDE support
- implement domain logic in concepts my domain experts understand
When to choose
- You need to design a DSL with a full IDE experience (completion, intentions, type checking) without building editor tooling from scratch
- Your notation must be non-textual - mathematical symbols, tables, diagrams, or forms - via projectional editing
- You want to generate code for multiple target languages from one language definition
- You are building extensible language families for a specific engineering domain, like embedded software or legislation
When to avoid
- You only need a lightweight textual DSL parsed from source files - parser generators like ANTLR are simpler
- Your workflow depends on plain text files and standard diff/merge tooling, since projectional models are not text
- You want a quick one-off scripting tool - MPS has a significant learning curve and is aimed at language engineering
