我发现 XeLaTeX 的输出过于冗长。我真的只对错误（而不是警告）和有问题的行号感兴趣。我还希望 xelatex 在出现错误时停止（退出）。有没有可以实现这一点的魔法咒语？
答案1
如果你想摆脱所有警告，你可以加载silence包裹
\usepackage{silence}
然后发出命令
\WarningsOff*
如果需要，请查看其文档以了解选择性警告过滤和错误过滤。
只要记住警告就是它们本来的意义所在：它们会警告你文档中存在错误。
对于您的后一个请求，如果您希望 xelatex 在出现错误时停止（并退出），请添加--halt-on-error到命令行，否则，如果您希望提示在哪里决定做什么，请添加--interaction=errorstopmode到命令行。

TeX Livetexfot提供了一个由 Karl Berry 编写的 Perl 脚本。
跑步
texfot --ignore '(Warning|Overfull|Underfull)' pdflatex test
test.tex在以下文件上
\documentclass{article}
\begin{document}
\hbox to 0pt{aaa} % Overfull \hbox
\hbox to 100pt{x} % Underfull \hbox
{\fontsize{125}{0}\selectfont a} % font warning
\foo % undefined control sequence
\end{document}
控制台上的输出是
/Library/TeX/texbin/texfot: invoking: pdflatex test
This is pdfTeX, Version 3.14159265-2.6-1.40.17 (TeX Live 2016) (preloaded format=pdflatex)
! Undefined control sequence.
l.11 \foo
! Emergency stop.
l.11 \foo
! ==> Fatal error occurred, no output PDF file produced!
如果您发现其他应该忽略的内容，您可以根据自己的意愿自定义正则表达式字符串。
文件.log仍然完整生成：

答案3
尝试了一整天后，我最终使用 pyparsing 编写了我自己的 python 脚本：
#!/usr/local/bin/python
# file: xelatex-clean.py
def spoil(l):
if type(l) == list:
if len(l) == 0:
return ''
elif len(l) == 1:
return spoil(l[0])
return l
def pprint(nested, max_level, level = 0, indent = ' '):
for i,c in enumerate(nested):
nested[i] = spoil(c)
for c in nested:
if type(c) != list:
print (indent*level + c.replace('\n','\n' + indent*level))
elif level < max_level:
pprint (c, max_level, level + 1)
if __name__ == '__main__':
import sys
from pyparsing import nestedExpr, OneOrMore, Word, printables
if len(sys.argv) != 2:
print ("Usage: xelatex document.tex | xelatex-clean.py <nesting-level>")
xelatex_output = sys.stdin.read()
l = nestedExpr('(',')',content=OneOrMore(Word(printables+' \n',excludeChars='()'))).parseString('(%s)'%xelatex_output).asList()[0]
pprint(l,int(sys.argv[1]))
spoil 函数会删除空括号或内联括号，否则这些括号会用空格填充输出。我没有花太多时间去看看是否可以使用标准 pprint 函数代替我自己的函数。希望这对你有帮助。
用法：
<xelatex command> | xelatex-clean.py <nesting-level>
