Extensions

Extensions are not available in v1. Sirius ships with built-in language support via LSP templates under gui/languages/.

Roadmap

We plan a lightweight extension format (manifest + Python entrypoint) similar to VS Code’s contribution model, but scoped to:

  • New language grammars and LSP launchers
  • Custom agent tools (read-only until reviewed)
  • Theme packs

There is no timeline yet. Follow the GitHub repository for announcements.

Contributing languages today

To add a language without waiting for extensions, follow docs/ADD_NEW_LANGUAGE.md in the main repo and copy a template from gui/languages/templates/.
