Implementation of LIonCore in MPS

Dependencies

• MPS version 2021.1

• lioncore-java

  For updating to a newer version of this dependency, change the version number in build.gradle.kts and run ./gradlew resolveLibs .

Setup

• run ./gradlew resolveLibs to download required libraries.
• In MPS, create path variable lioncore-mps.home pointing to the directory containing this readme file.

Overview

• io.lionweb.mps.m3 contains LIonCore meta-meta-model as MPS language

• io.lionweb.mps.converter contains converters between deployed / models of MPS languages and LIonWeb languages (expressed as instances of io.lionweb.mps.m3).

  io.lionweb.mps.converter.test tests these converters.

• io.lionweb.mps.json contains converters beween

  • deployed MPS languages and LIonWeb languages in JSON format
  • instances of io.lionweb.mps.m3 and LIonWeb languages in JSON format
  • M1 models in MPS and LIonWeb JSON format

  io.lionweb.mps.json.test tests these converters.

• org.lionweb.lioncore.java contains (un-)serializers to read/write LIonWeb JSON format

• io.lionweb.mps.converter.lang and its runtime io.lionweb.mps.converter.lang.runtime make it easier to use and test all aforementioned converters

• io.lionweb.mps.server.plugin teaches MPS to act as a bulk model server / repository.

• io.lionweb.mps.m3.selfdescription is a playground

• The remaining languages are used inside the tests.

Build

It is suggested to use JDK 11. Later JDKs could cause errors.

Run:

./gradlew build

Documentation

Refer to documentation.

Publishing

Run:

./gradlew publish

To publish to either Sonatype (for snapshot versions, i.e., versions ending with -SNAPSHOT) or to Maven Central. For doing that you need to configure your sonatype credentials in ~/.gradle/gradle.properties:

ossrhUsername=<username>
ossrhPassword=<password>

In order to be able to publish you need to register on sonatype and then asked to be added to the list of users authorized to publish under io.lionweb.

Alternatively one can use Maven Local while testing:

`./gradlew publishToMavenLocal`
