有没有办法可以抑制除错误之外的所有 LuaTeX 输出？

有没有办法可以抑制除错误之外的所有 LuaTeX 输出？

基本上，TeX 有很多要说的，而我对其中的大部分都不感兴趣。如果我感兴趣的话，我会阅读日志。silence 包会抑制输出，但它也会抑制输出到日志，而且，它只会抑制部分输出，远远不够。我不希望每次运行命令时都出现数百行输出，但我仍然希望被告知错误并给出提示。

我知道我可以运行类似

lualatex myfile.tex 1>/dev/null

或者批处理模式，简单地抑制所有输出。但是当 LuaTeX 告诉我编译错误时，它很有用，我想保留它，同时删除其他所有内容。

您可以使用报告回调关闭大多数消息，例如

\documentclass{article}

\usepackage{array}

\begin{document}

\zzz

\end{document}

产生终端输出
