Installing the Web Extension

The easiest is installing the extension from the Visual Studio Marketplace:

Installing from Source

You can build the extension from source and then install it with:

# set your editor (eg. EDITOR=codium)
EDITOR=code
version="$(jq -r .version < recalc-vscode/package.json)"

$EDITOR --install-extension "result/recalc-vscode-${version}.vsix"

The Webview Extension should automatically start when opening a file ending with .rc.
