# References Editor Sample

This is a sample extension that shows how an editor-based representation for the _Find References_ feature can be build.

It is not intended as a product quality extension.


- Select a symbol
- Select `F1 > Show All References`
- An editor opens to the side and show the references in a textual form

# How it works, what it shows?

- The extension implements and registers a [`TextDocumentContentProvider`](https://code.visualstudio.com/api/references/vscode-api#TextDocumentContentProvider) for a particular URI scheme.
- The content provider uses the [`vscode.executeReferenceProvider`](https://code.visualstudio.com/api/references/commands)-API command to delegate searching for references to the language extensions, like TypeScript, vscode-go, or C#
- The generated document initially contains a caption only and incrementally updates as each reference location is resolved.
- Add links for each result in the virtual document pointing to the reference.
- Add an entry to editor context menu via `package.json`

# How to run locally

* `npm run compile` to start the compiler in watch mode
* open this folder in VS Code and press `F5`
