mdwtools的語法包和graphicx之間的交互不良

Question

我正在編寫一個文檔，我想透過 包含一些圖像graphicx並\includegraphics使用syntax套件顯示一些 BNF 語法，但是當我嘗試將它們一起使用時，mdwtools我收到錯誤undefined control sequence帶有一些檔案名。

一個失敗的最小例子：

\documentclass{article}

\usepackage{syntax}
\usepackage{graphicx}

\begin{document}

\includegraphics{logo_uniud_black}

\end{document}

編譯這個我得到以下錯誤：

(/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.)

註解掉\usepackage{syntax}可以解決問題。也可以使用不包含下劃線的檔案名，這樣程式碼就不會失敗：

\documentclass{article}

\usepackage{syntax}
\usepackage{graphicx}

\begin{document}

\includegraphics{logouniudblack}

\end{document}

為什麼會出現此錯誤？有沒有辦法修復它而不重命名我必須包含的所有文件？

編輯：

實際上，即使是帶下劃線的節名也會產生問題，因此\include會引發類似的錯誤，例如原始碼：

\documentclass{article}

\usepackage{syntax}

\begin{document}

\include{sintassi_astratta}

\end{document}

我收到這些錯誤：

如果我沒記錯的話，不是尋找而是sintassi_astratta.tex尋找sintassi.tex。似乎syntax正在以某種破壞一切的方式重新定義下劃線。

Answer 1

該syntax包有一個nounderscore選項；然後您需要使用\_複合名稱。

如果您希望了解數學模式之外的_含義，請使用\_

\input{\detokenize{file_name}}

對於\includeor也類似\includegraphics。所以

\documentclass{article}

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

\begin{document}

\includegraphics{logo_uniud_black}

\end{document}

也能正常運作

\documentclass{article}

\usepackage{syntax}
\usepackage{graphicx}

\begin{document}

\includegraphics{\detokenize{logo_uniud_black}}

\end{document}

Answer 2

用於\string_底線

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