我有一本书，当我用 pdflatex 编译它时，它在 stdout 上产生了 20,000 行输出。我做了以下事情来减少输出：
\RequirePackage{silence}
\WarningFilter{Fancyhdr}{\headheight is too small}
\WarningFilter{textpos}{environment textblock}
%\pdfsuppresswarningpagegroup=1 % my pdftex isn't new enough
\hfuzz=999pt % reduce overfull hbox errors
\hbadness=10000 % reduce underfull hbox errors
这样就将输出缩减到 500 行。但是，这还是太多了。我想在没有错误的情况下将其缩减到零行，这样每次编译这本书时我都可以实际查看输出。剩余的无用输出似乎主要包括以下类别：
- 说明我已加载的软件包的消息：
(/usr/share/texlive/texmf-dist/tex/latex/fancyhdr/fancyhdr.sty) - 通过 包含的每个文件都有一条消息
includegraphics。 - 针对每种使用的字体都给出一条信息：
<</usr/share/texlive/texmf-dist/fonts/type1/p ublic/amsfonts/cm/cmsy10.pfb>> - 正在包含的文件。
有些类型的消息似乎是无法阻止的，因为它们被编码到 TeX 本身中。因此，除了对输出进行某种后过滤之外，似乎没有其他选择。我必须编写自己的过滤器吗，还是其他人编写了一些东西来执行此操作？

现有的一些自动构建工具能够进一步减少编译的终端输出。一个相对较新的参与者（我将在这里重点介绍）是ltx2any。该系统提供以下形式的构建输出：
$> ltx2any bibtex_test.tex [ltx2any] Initialising ... [ltx2any] pdflatex(1) running ... Done [ltx2any] bibtex running ... Error [ltx2any] pdflatex(2) running ... Done [ltx2any] pdflatex(3) running ... Done [ltx2any] pdflatex(4) running ... Done [ltx2any] There were 1 error and 3 warnings. [ltx2any] Output generated at bibtex_test.pdf [ltx2any] Assembling log files ... Done [ltx2any] Log file generated at bibtex_test.log.md
终端上的简短摘要输出会提醒用户在构建过程中遇到的任何错误，并且可以在 Markdown 日志文件（还提供 pdf 日志文件选项）中查看有关任何错误的更多详细信息。 (La)TeX 的完整、纯净的日志文件也可在其通常的位置找到。
虽然这并不严格满足您的零线要求，但此处的输出肯定会适合合理大小的终端窗口而无需滚动，而且我认为微创的视觉反馈很好。
构建系统ltx2any可高度配置，适用于多种不同的引擎和工作流程。请参阅 GitHub 存储库以了解更多详细信息和功能示例。

由于似乎没有人知道预先存在的解决方案，因此我编写了以下 ruby 脚本。
#!/usr/bin/ruby
# This program filters TeX's output to get rid of stuff I don't care about.
# It reads stdin, writes stdout.
