theoremref 包和其他语言

Question

我使用西班牙语写作并使用theoremref包。我对包有一点问题\thref：

\documentclass{article}

\usepackage{theoremref,amsthm}
\usepackage[spanish]{babel}
\usepackage[latin1]{inputenc}

\theoremstyle{plain}

\newtheorem{teo}{Teorema}
\newtheorem{lem}{Lema}

\begin{document}

\begin{lem}[Exacto]
Lema exacto \thlabel{exact}
\end{lem}

\begin{lem}[Zorn]
Lema de Zorn\thlabel{zorn}
\end{lem}

\begin{teo}[Principal]
Teorema principal\thlabel{main}
\end{teo}

\thref{exact,zorn,main}

\end{document}

如您所见，该命令运行正常，但有一个细节：ref 输出中的单词and（在引理数字和定理之间）。我用西班牙语写作，但这以英语显示。我如何翻译包 theoremref？

PD：我绕过了这种情况，\thnameref{exact}s \ref{exac} y \ref{zorn}但这不是一个优雅的方法。

Answer 1

“and” 和逗号在包中是硬编码的thmref。以下修补了一些内部命令，使其更符合西班牙语：

\documentclass{article}

\usepackage{theoremref,amsthm}
\usepackage[spanish]{babel}
\usepackage[latin1]{inputenc}

\theoremstyle{plain}

\newtheorem{teo}{Teorema}
\newtheorem{lem}{Lema}

\usepackage{etoolbox}

\begin{document}

\begin{lem}[Exacto]
Lema exacto \thlabel{exact}
\end{lem}

\begin{lem}[Zorn]
Lema de Zorn\thlabel{zorn}
\end{lem}

\begin{lem}[Foo]
Lema de Foo\thlabel{foo}
\end{lem}

\begin{teo}[Principal]
Teorema principal\thlabel{main}
\end{teo}

\subsubsection*{English, original version:}
\noindent
\thref{exact}\\
\thref{exact,zorn}\\
\thref{exact,zorn,foo}\\
\thref{exact,main}\\
\thref{exact,zorn,main}\\
\thref{exact,zorn,foo,main}

\makeatletter
\patchcmd\thmref@doref{and }{y }{}{%
  \errmessage{\noexpand\thmref@doref could not be patched}%
}
\patchcmd\thmref@doref{\ifthmref@final,\fi}{}{}{%
  \errmessage{\noexpand\thmref@doref could not be patched}%
}
\patchcmd\thmref@flush{, and}{\space y}{}{%
  \errmessage{\noexpand\thmref@flush could not be patched}%
}
\patchcmd\thmref@flush{\space and}{\space y}{}{%
  \errmessage{\noexpand\thmref@flush could not be patched}%
}
\makeatother

\subsubsection*{Spanish, patched version:}
\noindent
\thref{exact}\\
\thref{exact,zorn}\\
\thref{exact,zorn,foo}\\
\thref{exact,main}\\
\thref{exact,zorn,main}\\
\thref{exact,zorn,foo,main}

\end{document}

或者多语言版本：

\documentclass{article}

\usepackage{theoremref,amsthm}
\usepackage[english,spanish]{babel}
\usepackage[latin1]{inputenc}

\theoremstyle{plain}

\newtheorem{teo}{Teorema}
\newtheorem{lem}{Lema}

\usepackage{etoolbox}

  \renewcommand*{\thmrefandtypename}{\space and\space}%
  \renewcommand*{\thmreffinalcommaname}{,}%
  \renewcommand*{\thmreffinaland}{, and}%
  \renewcommand*{\thmreftwoand}{\space and}%

\addto\captionsspanish{%

\patchcmd\thmref@flush{, and}{\thmreffinaland}{}{%
