This projects requires Java 8, to maximize compatibility.
We require Java 11 for building the project, while the artifacts published are compatible with Java 8.
Take a look at the Documentation.
While new features are being added, and the project is evolving, the core features are solidly implemented. The library is mature and used in production.
The project is actively maintained. Feel free to open issues to ask any question, help, or support.
For visibility on the future plans regarding this project refer to the Roadmap.
Currently the project is on-par with the LionWeb specifications.
In particular, this library supports both version 2023.1 and 2024.1 of the specs.
dependencies {
implementation("io.lionweb.lionweb-java:lionweb-java-2024.1-core:$lionwebVersion")
}
Before opening in IDEA run:
./gradlew setup
This will generate necessary classes.
Contains LionCore (M2) and LionWeb (M1) implementations in Java, including (de-)serializers from/to JSON.
Contains im/exporters to convert models between LionCore ↔ Ecore and LionWeb ↔ EMF.
Some of LionCore's built-in elements have no direct representation in Ecore.
This sub-project is an Eclipse project that defines an EPackage builtins to host the equivalent elements in Ecore.
The language's nsURI is http://lionweb.io/lionweb-java/emf/core/builtins/2023.1.
Functionalities to connect to the LionWeb Server. It also includes an in-memory server, paired with a Client exposing the same interface as the interface for connecting to the LionWeb Server.
Facilities to write functional tests against the LionWeb Server.
The Changelog is here.
To ensure proper testing coverage we configured Jacoco.
You can run ./gradlew jacocoTestReport and then find the report for each module, under build/reports/jacoco.
This project is part of the LionWeb initiative.
