哪个 LaTeX 命令会打印有关“Overfull \hbox”的警告消息？

我想覆盖打印的命令Overfull \hbox...，但似乎不是\GenericWarning。它是什么？

这来自于 tex 引擎，在经典 TeX 中无法改变。

在 luatex 中有一个回调允许用任意 Lua 代码替换警告，所以在这里我用它来引发 tex 错误。

在此处输入图片描述

\documentclass{article}

\makeatletter
\directlua{
luatexbase.add_to_callback(
"hpack_quality",
function(i,d,h,f,l)
if(i=="overfull") then
tex.error("Overfull line: ".. 
          string.format("\@percentchar.4f",d/65536,3) .. 
          "pt in paragraph lines " ..
           f .. "-" .. l)
end
end,
"error on overfull hbox"
)
}
\makeatother

\begin{document}

产生三个错误：
