# [NTG-context] Footnote rules for bidi document

I see your point, Hans. For what it's worth, that's the default for mixed
Persian/English documents unless one uses a system that cannot do it. For
instance, FarsiTeX and XePersian provide that as default behavior.

That said, I'm not asking for this to be the default. I only want to know
how it can be achieved. The code will be put in my style file or module.

Is it possible to determine the direction of the first line of footnote
block while typesetting the footnote rule? I imagine it should not be
difficult in Lua. Note that this may be the leftover from a long footnote
that started on some previous page.
