Option to %cd relative to current file

[thewh1teagle]

It will be useful to be able to %cd relative the current file.
eg. %cdr ..
will always cd to the parent folder of the folder of the current jupyter notebook.
Why it's important? because if we want to re-run the cells currently it will cd into wrong upper directory.

You can do this relative to $JPY_SESSION_NAME, which is the notebook path if the kernel was started for a notebook

from pathlib import Path
nb = Path(os.environ["JPY_SESSION_NAME"])
%cd {nb.parent}/..
