Xtext Visual Studio Code Example

This is an Example showing the Visual Studio Code Integration of Xtext using the Microsoft Language Server Protocol.

Build Status

Quickstart

Requires Visual Studio Code (VS Code) with version 1.4.0 or greater to be on the path as code and Java 8+ available as java.

  • Run ./gradlew startCode

This will start VS Code and after a few seconds load the demo folder of this repository.

Project Structure

  • vscode-extension (node based VS Code extension to run with a separate server using socket)
  • vscode-extension-self-contained (node based VS Code extension to run with a embedded server using process io)
  • 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

Building in Details

  1. Make sure that java -version is executable and pointing to a Java 8+ JDK.
  2. Type code. If the command is not known, open VS Code and select View / Command Palette. Enter code and select to install code on the path.
  3. Run ./gradlew startCode to build the DSL and the VS Code extensions.

Scenario 1 (embedded server)

  1. Install the self-contained extension into VS Code using code --install-extension vscode-extension-self-contained/build/vscode/vscode-extension-self-contained-0.0.1.vsix
  2. Run a second instance of vscode on the demo folder code demo

Scenario 2 (client-only with separate server process)

  1. Run ./gradlew run or launch RunServer from Eclipse.
  2. Open vscode-extension in VS Code and F5 to launch new editor (you may need a Debug -> Start Debugging initally).
  3. Open folder demo in the new editor.

Build VS Code Extension Package manually (manually Gradle)

npm install -g vsce
cd vscode-extension
vsce package
cd ../vscode-extension-self-contained
vsce package

Hints

For Other Xtext/VSCode versions please also check other branches for newer/older Xtext Versions that also support newer/older vscode versions Atom language client is dead. We plan to update to a fork. See itemis#73
