mdwtools 语法包与 graphicx 之间的交互不良

mdwtools 语法包与 graphicx 之间的交互不良

我正在编写一个文档，其中我想同时包含一些图像graphicx和使用包\includegraphics显示一些 BNF 语法，但是当我尝试一起使用它们时，我收到了错误syntaxmdwtoolsundefined control sequence有一些文件名。

失败的最小示例：

\documentclass{article}

\usepackage{syntax}
\usepackage{graphicx}

\begin{document}

\includegraphics{logo_uniud_black}

\end{document}

编译此程序时出现以下错误：

(/usr/share/texlive/texmf-dist/tex/latex/latexconfig/epstopdf-sys.cfg))
! Undefined control sequence.
\filename@simple ...#2\\}\fi \edef \filename@base 
                                                  {#1}
l.8 \includegraphics{logo_uniud_black}

   [omissis]

! Undefined control sequence.
\filename@simple ...#2\\}\fi \edef \filename@base 
                                                  {#1}
l.8 \includegraphics{logo_uniud_black}

(That makes 100 errors; please try again.)

注释掉\usepackage{syntax}可以修复此问题。使用不包含下划线的文件名也可以，这样此代码就不会失败：

\documentclass{article}

\usepackage{syntax}
\usepackage{graphicx}

\begin{document}

\includegraphics{logouniudblack}

\end{document}

为什么我会收到此错误？它与文件名中的下划线有何关系？有没有办法修复它而不重命名我必须包含的所有文件？

编辑：

实际上，即使带有下划线的部分名称也会产生问题，因此\include会引发类似的错误，例如源代码：

\documentclass{article}

\usepackage{syntax}

\begin{document}

\include{sintassi_astratta}

\end{document}

我收到这些错误：

如果我没记错的话，不是在寻找而是sintassi_astratta.tex在寻找sintassi.tex。这似乎syntax是在以某种方式重新定义下划线，从而破坏了一切。

答案1

该syntax包有一个nounderscore选项；然后您需要使用它\_作为复合名称。

如果你希望在数学模式之外有_含义，那么使用\_

\input{\detokenize{file_name}}

\include对于或也类似\includegraphics。因此

\documentclass{article}

\usepackage[nounderscore]{syntax}
\usepackage{graphicx}

\begin{document}

\includegraphics{logo_uniud_black}

\end{document}

将会起作用

\documentclass{article}

\usepackage{syntax}
\usepackage{graphicx}

\begin{document}

\includegraphics{\detokenize{logo_uniud_black}}

\end{document}

答案2

用于\string_下划线

\includegraphics{/tmp/logo\string_uniud\string_black}
