escapeinside breaks when using \ref with a hypen

Open lucc opened this issue 2 years ago • 3 comments

If I \ref a label that contains a minus character from within minted (with escapeinside) the compilation breaks. Other labels work fine.

The mwe.tex:

\documentclass{article}
\usepackage{minted}
\begin{document}
\section{First}\label{first}
\section{Second}\label{with-hyphen}
\begin{minted}[escapeinside=||]{python}
# | see \ref{first} |
print(1)
\end{minted}
\begin{minted}[escapeinside=||]{python}
# | see \ref{with-hyphen} (remove this line to make it compile) |
print(2)
\end{minted}
\LaTeX{} can reference \ref{with-hyphen}.
\end{document}

Compile with pdflatex -shell-escape -interaction nonstopmode mwe.tex

This is likely related to the minus character being handled specially to support style names with hyphens. There is an existing issue related to that (#294); fixing that will likely fix this reference issue as well.

It is not critical for me as I was able to rename my labels, just wanted to report it.

I once proposed that pygments uses \csname ... \endcsname in its latex formatter in https://github.com/pygments/pygments/issues/1770, though received no responses. The proposed change is https://github.com/muzimuzhi/pygments/commit/c068d4770ab3333101474397ceca1a362910c143 .
