Welcome to the work-in-progress documentation site for Spyglass, a project that aims at improving your editing experience with Minecraft: Java Edition data packs by providing handy features like auto-completion, real time diagnostics, semantic coloring and such.

The project is under a complete rewrite and is planned to support multiple text editors. For the legacy version of the project commonly known as Data-pack Helper Plus, check out the VS Code Marketplace.
