Copies the workspace-relative file path with the current line number(s) to the clipboard.

Works best with coding agents!

Right-click text: Editor text area context menu → Copy Reference
Keyboard: Default: Cmd+Shift+C (macOS) / Ctrl+Shift+C (Linux/Windows). Can be customized in Keyboard Shortcuts (copyref.copyReference command).

Clone the repo and install dependencies:

git clone https://github.com/sarisia/vscode-copyref
cd vscode-copyref
npm install

Open the folder in VS Code.
Press F5 — VS Code builds the extension and opens a new Extension Development Host window with the extension loaded.
In that window, open any file, make a selection, and try the keybinding or right-click menu.

npm run build       # one-shot bundle to dist/
npm run watch       # rebuild on every file save
npm run compile     # type-check only (no output)

npm run package     # produces vscode-copyref-<version>.vsix

Install locally with:

code --install-extension vscode-copyref-<version>.vsix
