(Sorry for the delay) Here's a more complicated test file that forces lua-widow-control to move a last line that contains bigfoot footnotes: \documentclass{article}
\usepackage{lua-widow-control}
\usepackage{bigfoot}
\DeclareNewFootnote{default}
\DeclareNewFootnote{Z}[alph]
\begin{document}
\vspace*{33\baselineskip}
One two three four five six seven eight nine ten. One two three four five six
seven eight nine ten. One two three four five six seven eight nine ten. One two
three four five six seven eight nine ten. One two three four five six seven
eight nine ten. One two three four five six seven eight nine ten. One two three
four five six seven eight nine ten. One two three four five six seven eight nine
ten. One two three four five six seven eight nine ten. One two three four five

\end{document}This issue looks fairly simple, but it's actually insanely complicated. To fix it, I had to rewrite around half of the Lua code. Most other TeX packages for footnotes use the standard To fix this, I rewrote lua-widow-control so that instead of manually moving the last line of the page to the next line, it instead sets a “no-op” output routine, then triggers the real one. This way, all that it has to do is expand one paragraph on the page, then TeX will handle moving the last line. To make TeX handle the inserts properly, all that it needs to do is set But this still doesn't actually help, since Anyways, this new code should (in theory) fully-support bigfoot footnotes, so you (hopefully) shouldn't need the The builder that generates the And thanks for the report! |
Issue
I'm working on pretty big project that uses both
