Sharing notebooks on the same machine? I.e. workaround for Access denied: File is outside the allowed directory.

[stephenlf]

Updating to Marimo 0.18.* breaks my team's workflow. We have individual Marimo instances running from our home directories, with a symlink to a shared-notebooks directory. Upgrading to 0.18.* makes it impossible to open notebooks in this shared-notebooks directory, throwing this error:

Access denied: File {file-path} is outside the allowed directory.

What's the right way to get around this? Is there some way to whitelist symlinks in the file router?

Reproduce

mkdir /tmp/mo-symlink-demo
cd /tmp/mo-symlink-demo
ln -s /path/to/folder/with/notebooks .
uv run --with marimo marimo edit

# Open Marimo, open "notebooks" folder, and observe that error is thrown

@stephenlf ah sorry for breaking this workflow. we have a config follow_symlinks that we this should also adhere to.

in the meantime, do hardlinks works for you?

[stephenlf]

Is the follow_symlinks config exposed anywhere?

@stephenlf actually, i have a fix here for the next release: #7671
