Custom editors present as webviews, creating a chicken-and-egg problem: +- To populate outline: Text document must be the active editor +- To show custom UI: Webview must be the active editor +- These states are mutually exclusive in current VS Code architecture + +### Recommended Solutions + +Given these findings, the most practical approaches are: + +Success depends on: +- Proper language registration and file type association +- **Choice between outline integration OR custom editor display** (not both simultaneously) +- Robust DocumentSymbolProvider implementation for when text editor is active +- Custom tree view as primary solution for outline-like functionality +- Graceful error handling and fallback approaches + +#### Primary Recommendation: Custom Tree View +The most reliable solution remains creating a dedicated tree view that bypasses VS Code's outline system entirely: + +```typescript +// Custom tree view as outline alternative - most reliable approach +const outlineView = vscode.window.createTreeView('geoJsonOutline', { + treeDataProvider: customTreeProvider, + showCollapseAll: true +}); +``` + +#### Secondary Recommendation: User Choice +Allow users to choose between outline integration (text editor) and visual editing (custom editor) via settings or commands. + +While challenging, custom tree views provide outline-like functionality without the integration conflicts, making them the preferred solution for complex custom editors requiring both visual editing and structured navigation. + +## References + +- [VS Code Extension API Documentation](https://code.visualstudio.com/api) +- [Microsoft VS Code Extension Samples](https://github.com/microsoft/vscode-extension-samples) +- [VS Code Issue #97095: Support DocumentSymbolProvider in CustomTextEditor](https://github.com/microsoft/vscode/issues/97095) +- [VS Code Issue #101476: Support outline for custom editors](https://github.com/microsoft/vscode/issues/101476) +- [Custom Editor API Reference](https://code.visualstudio.com/api/extension-guides/custom-editors) \ No newline at end of file diff --git a/media/plotJsonEditor.js b/media/plotJsonEditor.js index a2f5439..cf943d3 100644 --- a/media/plotJsonEditor.js +++ b/media/plotJsonEditor.js @@ -2,6 +2,8 @@ const vscode = acquireVsCodeApi();
