Because there are too many Underfull \vbox (badness 10000) has occurred while \output is active messages, I am trying to use \hbadness=10000 to suppress them. If I use TeXworks, then where should I locate \hbadness=10000? I tried the following, but it did nothing.

\documentclass{book}
\hbadness=10000
\begin{document}
This is the document with many underfull vbox messages.
\end{document}

Thanks for your help.

    setting \hbadness=10000 (or \vbadness) means you are telling tex you really do not care how bad the output is. Why use TeX at all in that case? It would be far better to fix the errors in your document that are causing the warnings. However putting it where you show will work. If you have an example where it is not working as expected then edit the question toshow an example of your issue. – David Carlisle Jul 12 '20 at 15:31
  • but to suppress vbox errors you need to set \vbadness not \hbadness – David Carlisle Jul 12 '20 at 15:32
  • The problem is that it's not horizontal badness that's to blame, but it's vertical badness, so you would need to set \vbadness and not \hbadness. That said, you may want to examine what the root cause of the underfull \vbox error is rather than just turn off the error. – Don Hosek Jul 12 '20 at 15:36
  • My apologies, but I was not me—I didn't think about the difference between H and V there. Thanks for all. – Junyong Kim Jul 12 '20 at 15:51

For vbox you would set \vbadness not \hbadness.

This document produces the warning if you remove the marked line.

\documentclass{book}

\vbadness=10000 % don't do this
\begin{document}
aaa


bbb


\pagebreak
ccc
\end{document}

However by setting \hbadness or \vbadness to 10000 you are telling TeX not to warn you even if its internal checks on the quality of the output say that it is as bad as possible. It would be much better to fix the errors that are causing the warnings rather than just silence the warning.

  • Thanks for help. I was combining multiple documents and wanted to check other warnings first before the bad boxes. Of course I wanted to correct all the unexpected underfull messages but after the warnings—there were too many underfull messages related to undirected footnotes, so I couldn't even match them all. – Junyong Kim Jul 12 '20 at 16:00
