# Editor Extensions Extensions are standard VL patches saved with a `.HDE.vl` suffix. They run automatically when open in the editor. ## File Naming | Context | Required Name | |---|---| | Standalone extension | `VL.MyExtension.HDE.vl` | | Extension-only NuGet | `VL.MyExtension.HDE` (package ID) | | Mixed NuGet main doc | `VL.MyPackage.vl` | | Mixed NuGet extension doc | `VL.MyPackage.HDE.vl` | ## Required NuGet References - **VL.HDE** — provides `Command` node, window types, `WindowFactory` - **VL.Lang** — provides API nodes under the `Session` category ## Command Node Registers a command in the editor menu: | Pin | Purpose | |---|---| | `Label` | Menu text | | `Visible` | Show/hide the command | | `Shortcut` | Keyboard binding | | Output | Triggers (bang) on activation | Multiple `Command` nodes can live in one `.HDE.vl` document. **Warning**: A runtime error in one command may affect all others in the same document. ## Window Types | Type | Behavior | |---|---| | `SkiaWindow` | Slimmed-down Skia renderer window | | `SkiaWindowTopMost` | Always-on-top, no focus steal | ## Docking Wrap window with `WindowFactory` node. Connect `WindowContext` and `Window` pins. Template: `VL.HDE/Template.HDE.vl` ## API Access Access hovered/selected nodes, read/write pins via `VL.Lang` `Session` category nodes. Browse available API in the HelpBrowser's `API` section. ## Developer Shortcuts - **Shift+F9** — restarts all extensions simultaneously ## Limitations - Settings panel integration is not yet possible - Extensions only run in the editor, not in exported applications
