Custom-MADE DSLs

This repository contains Xtext DSL projects that will be used by Custom-MADE Xtext-WebUI (see https://github.com/schubmat/Custom-MADE/). The languages come along with:

• a DSL project
• an ...ide project containing the language server for the specified DSL (cf. Language Server Protocol)
• a test project
• a websocket project that is wrapping the language server so that it can be tied to another application

Quickstart

• Run ./gradlew run

This will start the server with the help of org.xtext.example.mydsl.websockets.RunWebSocketServer3.

Project Structure

• org.xtext.example.mydsl (contains the DSL)
• org.xtext.example.mydsl.ide (contains the DSL specific customizations of the Xtext language server)
• org.xtext.example.mydsl.tests
• org.xtext.example.mydsl.websockets (contains the code to launch a websocket and the language server and tie them to each other)

Building in Details

1. Make sure that java -version is executable and pointing to a Java 11 JDK or a Java 13 JDK.

Scenario 1 -- build and run the LSP binary

1. Run ./gradlew distZip.
2. Go to zip file of the ide sub project (, e.g. find . -name "*ide*zip")
3. Inflate it
4. Find the binary file mydsl-socket, and
5. start it as follows:
   • ./mydsl-socket [PORT_THE_LSP_SHOULD_RUN_ON], e.g., ./mydsl-socket 38123

Scenario 2 -- install the language into the local Maven repository

1. Set the language name in settings.gradle file with the help of the rootProject.name attribute. Do it, for instance, as follows:
   • rootProject.name = '[PROJECT_NAME]',
   • e.g., rootProject.name = 'grammar_MDR_simplified'
2. Set the language version in gradle.properties file as follows:
   • version = [VERSION],
   • e.g., version = 1.0.0-SNAPSHOT
3. Run ./gradlew install.

Scenario 3 -- client-only with separate server process

1. Run ./gradlew run or launch RunServer from Eclipse.
