Polyglot Live Programming

Polyglot Live Programming with GraalVM, the Language Server Protocol (LSP), and VS Code.

Getting Started

1. Install our VS Code extension. This will also install the GraalVM VS Code extension (0.5.0 or later).
2. Select or install a Java 11 based GraalVM 20.3 or later on your system using the GraalVM extension.
3. Run the "Install the Live component with the GraalVM Updater (gu)" command via the Command Palette.
4. Disable the "Language Server: In Process Server" option in the settings of the GraalVM extension:
   Preferences → Settings → Extensions → GraalVM → Language Server: In Process Server
   and wait until it is connected to the GraalLS ("GraalLS is ready." shown in status bar).
5. Run the "Display Expression" (Ctrl + D) and "Babylonian Analysis" (Ctrl + B) commands while programming
   (Here are some examples to play around with).
