ContextMapper/context-mapper-dsl

This system is a Domain-Driven Design modeling tool that provides a comprehensive IDE and language server for editing, validating, and transforming domain models. It supports multiple DSLs, including a Context Mapping Language (CML) and a Tactic DDD language, enabling users to define architectural patterns and service configurations. The system offers extensive code generation capabilities, producing diagrams (PlantUML, Context Maps), API contracts (MDSL), and code templates (JHipster, Freemarker). Additionally, it facilitates architectural refactoring, allowing users to split, merge, and extract bounded contexts and aggregates directly within the editor.

How it got here

2018 · DSL and IDE expansion

This period focused on significantly expanding the Context Mapper platform by introducing new domain-specific languages for Tactic DDD and ServiceCutter configuration. The team also enhanced the Eclipse IDE integration, providing comprehensive support for editing, validation, and code generation across all DSLs, while standardizing the build system with Gradle and updating dependencies.

2019–2024 · IDE and generator expansion

This period focused on significantly expanding the Context Mapper DSL's capabilities by introducing new code generators for MDSL, PlantUML, Sketch Miner, and Freemarker templates. The team also built out a comprehensive IDE integration, adding refactoring commands, quick-fixes, and hover support via the Language Server Protocol. Extensive test coverage was added to validate these new features and ensure the stability of the model resolution and serialization logic.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 4 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 995f486a9c — the exact code this score is about.
  • Scored under rubric rubric-2026.08.19. Score the same commit under that rubric and you get the same number.
