You can use the tree-viz tool in the tools folder to visually see the parser in action.
To use it, you need to have already built the project.
You also need to have a running HTTP server. For instance, you can do that by opening a terminal at the root folder and running:
npx http-serverThis should start a HTTP server at http://127.0.0.1:8080. You can now fetch the tools/tree-viz.html page from the HTTP server: open your browser and visit http://127.0.0.1:8080/tools/tree-viz.html.
