LuaLaTeX | preventing split footnotes

[coo...@nospamverizon.net]

Have a somewhat long-ish footnote I'd like to keep on a single page.
Thought all I needed to do was throw something like the following into
the preamble:

\interfootnotelinepenalty=10000


(i.e., bumping up a fair bit from the default of 100).

Alas, doesn't work - footnote is still split over two pages. I'm
compiling with LuaLateX, if that makes a difference.

Suggestions for things to try?

Thanks!

What does

\the\interfootnotelinepenalty

produce if put somewhere after \begin{document} and \maketitle
(if you have it)?

Perhaps \interfootnotelinepenalty is ok but the footnote is split
between two paragraphs. If it is the case, a simple redefinition of \par
at the beginning of the offending footnote may work:

\footnote{%
\def\par{\endgraf\penalty10000 }%
%
Blah blah blah (several paragraphs)...
}

Of course, adding the penalty by hand between the paragraphs is safer.

Best,
Paul

10000

(In other words, I'd over-written the default.)

However, this isn't doing the trick.

10000

(In other words, I *did* successfully over-ride the default). But it
isn't working.

But a key point is: it *DOES* work if I compile using LaTeX, but *DOES
NOT* work if I use LuaLaTex.

I'll give that a try. What I think is perhaps more of interest is
that it (increasing penalty) *DOES* work if I compile using LaTeX, but

But does the break happen between paragraphs?

It would really be easier to help you if you would give an example.
I at least can't reproduce the problem from the vage informations
you have given so far.

In the following example both lualatex + pdflatex behave the same
way: \interfootnotelinepenalty=10000 suppress the footnote split, if
there is no \par in the footnote. If I add paragraphs (by
commenting/removing the \let\lips@par\relax) then both break.

\documentclass{article}
\usepackage{lipsum}
\interfootnotelinepenalty=10000
\begin{document}
\makeatletter
\lipsum[1-3]\footnote{\let\lips@par\relax
\lipsum[1-3]}\lipsum[1-4]
\end{document}

Can't, since its part of a 900+ page book! ;-)

Yes, it does. Why that should differ between LaTeX and LuaLaTeX is
beyond me.

pdftex and luatex are not precisely the same. The problem is
intriguing, but the answer might be very far from the specific
situation: the latter might find a legitimate break point that
the former doesn't because of differences in the fonts used
or because of slightly different computations.

Add \nobreak after the blank line.

Different fonts, different line breaks, different page breaks,
different microtype features, different packages, different ...

The problematic page break involves two pages not 900.
