Linking to headers in different notebooks

[DKilkenny]

Hello,

I am looking for a way to link to a different notebook's header.

For example I have notebook A and B. Inside notebook A I want to link to # Header One contained in notebook B. I can't seem to find a way to do that. Does this feature exist? I know that you could reference an internal header in A if you're in that notebook but that same syntax doesn't seem to carry to external headers.

Heya, so you can either create a "target" for that header, e.g.

(my-reference)=
# Header One

[text](my-reference)

these reference are "project wide" (you will get a warning if any duplicates are found)

or use this "more advanced" sphinx configuration (I guess this is not documented in the jupyter-book documentation yet): https://myst-parser.readthedocs.io/en/latest/using/syntax-optional.html#auto-generated-header-anchors

Got it. Thank you!
