Add anchors to filepath?

Is it possible to, when using filepath= to open a specific file, specify a section/anchor to jump to? For example, if I have this in my file myfile.ipynb:

<a id='section2'></a>

I’d love to be able to use filepath=myfile.ipynb#section2 to open that file to that anchor.

It looks like something currently sees # in filepath and redirects me to a prompt to enter a token or password. I’ve tried various things with urlpath as well.

Thanks!

BinderHub uses a token to access to the notebook server for each launch (for each temporary user). Just before redirecting to user server, it logs “server running at …/tree?token=xyz”. But in your case server url becomes “/tree/myfile.ipynb#section2?token=xyz” and because token parameter is behing #, it is ignored and you are redirected to login page. So I think it is now not possible to have a file path with anchor.

To have it working the server url must be generated as “/tree/myfile.ipynb?token=xyz#section2” and I think this can be achived by updating here: https://github.com/jupyterhub/binderhub/blob/5544f704cb0dd9b8d3d67442a0c744e1ddcb6089/binderhub/static/js/src/image.js#L37-L58

Hi 👋 I think this is something that has to be handled by the application (JupyterLab or notebook), not BinderHub. If you have more questions please use the Jupyter community forum https://discourse.jupyter.org/.
