Note that you will need Java 11 SDK installed and referenced by the JAVA_HOME environment variable. Here is an illustration of how code generation works: Code generation is based on Xtext and the Rosetta DSL itself is expressed using Xtext. Ecore therefore acts the pivot that allows to transform the model originally expressed in the Rosetta DSL into the model expressed in the chosen programming language. This Ecore model is then accessible via an API hook in this repository.Įcore is a representation of a syntax tree, which contains the entire information about a given model. The files are parsed using an ANTLR-generated parser and an Ecore model instance is produced. Code generation works by allowing API hooks to access an Ecore representation of the model. The Rosetta DSL is based on the Eclipse Modelling Framework. The languages currently supported are:Ĭode generation consists in translating from the Rosetta DSL syntax into the syntax of the chosen programming language. The Rosetta Code Generator repository provides additional code generators and allows the community to contribute code generators in any other languages.

The Rosetta DSL repository features one built-in code generator: Rosetta is an open source Domain-Specific Language (DSL) comprising a syntax (or grammar) and a set of code generators. Distribution in the chosen programming language will be automatically released with the model and version-controlled, providing firms with more robust control over the adoption of model updates in their own systems. The mechanism is also future-proof to future version updates of the model. Systematically providing the domain model as executable code virtually eliminates this effort and replaces it with only having to develop code generation into another programming language.

Software engineers need to turn those technical requirements into codeĮach step comes with the risk of misinterpretation and implementation error, and the process is duplicated across each firm looking to adopt the standard, ultimately adding up to high implementation costs across the industry.

Business analysts need to translate the above into a set of technical requirements.

Domain experts need to understand the intent of the entire standard content.

The power of distributing a technical standard as a domain model is that you do not have to re-implement that technical standard in your particular language.īy contrast, traditional implentation of a technical standard that may be distributed in prose looks as follows: This project uses JDK 11 Why Code Generation? ¶

Do you want to adopt a technical standard expressed as a domain model in the Rosetta DSL, but in a language other than the default (Java) distribution? You can use this guide to write your own code generator in the language of your choosing.
