Bagaimana cara mengecualikan perintah \ label di latexdiff

Dec 20 2020

Dalam beberapa kasus, file yang dihasilkan oleh latexdiff akan berisi label yang ditentukan banyak, yang dapat menyebabkan kesalahan kompilasi. Berikut ini contohnya:

old.tex

\documentclass{article}
\usepackage{amsmath}
\begin{document}
Two remarks on the marvelous formula. 

\begin{equation}\label{eq:mass_energy}
    E = mc^2
\end{equation}
\end{document}

new.tex

\documentclass{article}
\usepackage{amsmath}
\usepackage{theorem}
\newtheorem{theorem}{Theorem}
\begin{document}

\begin{theorem}\label{thm:mass}
We have 
    \begin{equation}\label{eq:mass_energy}
        E = mc^2
    \end{equation}   
\end{theorem}

\end{document}

Seperti yang Anda lihat, masalahnya adalah yang \labeltermasuk dalam cakupan \DIFdel. Saya mencoba menambahkan opsi --exclude-safecmd=labelseperti yang disarankan di sini , tetapi tidak membantu. Bagaimana saya bisa menghindari masalah ini?

Memperbarui

Saya menggunakan perintah

latexdiff old.tex new.tex > diff.tex

dengan LATEXDIFF 1.3.1.1 (Algoritma :: Diff 1.15 jadi, Perl v5.30.1).

File diff Anda tidak lengkap dan jika saya menjalankan latex diff old.tex new.texsaya mendapatkan format berbeda yang tidak error, sangat sulit untuk diuji tetapi saya berasumsi bahwa jika preampbe Anda memiliki

\providecommand{\DIFdel}[1]{{\protect\color{red}\sout{#1}}}                      %DIF PREAMBLE

Anda bisa mengubahnya menjadi

\providecommand{\DIFdel}[1]{{\def\label##1{}\protect\color{red}\sout{#1}}}                      %DIF PREAMBLE

untuk menonaktifkan label di wilayah yang dihapus.
