Spelunk IDE — the Python IDE for Cave Engine

Write Cave Engine scripts with an editor that actually knows the engine.

• Autocomplete for the whole Cave API, read from the stubs of your own Cave Engine install (Steam, itch.io or standalone), with docs on hover and go-to-definition. Your scene inside the code: entity, component, template, sound and timeline names complete inside strings, straight from the open project through Remote Control. Run in Cave with one key and see the live editor context, scene graph and asset browser in a visual panel.

• AI that knows Cave: Claude Code, Gemini CLI or Codex (GPT), using your own account, with tools to look up the API, your assets and your open files. Refactoring: extract function/method (parameters and return values inferred, like Rider), split editor, back/forward navigation.

• Notebook for snippets and how-tos that work across projects, exported as Markdown, PDF, PNG, or code images for posts.

• VS Code–style extensions, themes and keymaps (VS Code, IntelliJ, Visual Studio).
• English, Portuguese and Spanish. No telemetry: everything stays on your computer.
• Windows 10/11 (64-bit). Requires Cave Engine installed (the API comes from your install). Installer and portable versions included. All 1.x updates included.
