Agent skill
vvvv-editor-extensions
Helps create vvvv gamma editor extensions — .HDE.vl file naming, Command node registration with keyboard shortcuts, SkiaWindow/SkiaWindowTopMost window types, docking with WindowFactory, and API access to hovered/selected nodes via VL.Lang Session nodes. Use when building editor plugins, custom tooling windows, or automating editor workflows.

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
Commandnode, window types,WindowFactory - VL.Lang — provides API nodes under the
Sessioncategory
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
