如何向 hypersetup 提供标题和作者变量？

我尝试使用以下命令动态设置 pdf 元数据：

\def\date#1{\def\@date{#1}}
\def\author#1{\def\@author{#1}}
\def\title#1{\def\@title{#1}}
\def\subtitle#1{\def\@subtitle{#1}}
\def\location#1{\def\@location{#1}}
\def\thesisdirector#1{\def\@thesisdirector{#1}}
\def\thesiscodirector#1{\def\@thesiscodirector{#1}}
\def\discipline#1{\def\@discipline{#1}}
\def\doctoralschool#1{\def\@doctoralschool{#1}}
\def\doctoralschoolnumber#1{\def\@doctoralschoolnumber{#1}}
\def\nationalthesisnumber#1{\def\@nationalthesisnumber{#1}}

\makeatletter
\hypersetup{
    final       = true,
    colorlinks  = true,
    urlcolor    = blue,
    citecolor   = blue,
    linkcolor   = MidnightBlue,
    unicode     = true,
    linktoc     = section,
    pdfauthor   = {\@author},
    pdfkeywords = {biocomputing, biotechnology, software , scientific},
    pdftitle    = {\@title},
    pdfsubject  = {Genomic expert annotation}   
}
\makeatother

或这个

\makeatletter
\def\date#1{\def\@date{#1}}

\def\author#1{\gdef\@author{#1}\gdef\@@author{#1}}
\let\@@author\@empty
\def\title#1{\gdef\@title{#1}\gdef\@@title{#1}}
\let\@@title\@empty

\def\subtitle#1{\def\@subtitle{#1}}
\def\location#1{\def\@location{#1}}
\def\thesisdirector#1{\def\@thesisdirector{#1}}
\def\thesiscodirector#1{\def\@thesiscodirector{#1}}
\def\discipline#1{\def\@discipline{#1}}
\def\doctoralschool#1{\def\@doctoralschool{#1}}
\def\doctoralschoolnumber#1{\def\@doctoralschoolnumber{#1}}
\def\nationalthesisnumber#1{\def\@nationalthesisnumber{#1}}


\hypersetup{
    final       = true,
    colorlinks  = true,
    urlcolor    = blue,
    citecolor   = blue,
    linkcolor   = MidnightBlue,
    unicode     = true,
    linktoc     = section,
    pdfauthor   = {\@@author},
    pdfkeywords = {biocomputing, biotechnology, software , scientific},
    pdftitle    = {\@@title},
    pdfsubject  = {Genomic expert annotation}   
}
\makeatother

这段代码被放在所需包之后，放入我的 cls 文件中。

但那不成立：

You can't use `\spacefactor' in internal vertical mode. \maketitle

我同意你的观点，这是一个常见的错误。我发现了很多报告（一些参考：1，2）

但每次答案都没有MWE或者不起作用

谢谢你的光芒

解决了

问题是 hypersetup 声明位于所需包之后的 cls 文件中。在此位置定义了变量，但设置为其最终值。我将 hypersetup 语句移动到设置了 title 和 author 变量之后。这样就成功了。

在我的 cls 文件中

\RequirePackage[xetex]{hyperref}
\def\date#1{\def\@date{#1}}
\let\@date\@empty

\def\author#1{\def\@author{#1}}
\let\@author\@empty

\def\title#1{\def\@title{#1}}
\let\@title\@empty

\def\keywords#1{\def\@keywords{#1}}
\let\@keywords\@empty

进入主 tex 文件：

\author{blah}
\title{blah}

\makeatletter
\hypersetup{%
    final       = true,
    colorlinks  = true,
    urlcolor    = blue,
    citecolor   = blue,
    linkcolor   = MidnightBlue,
    unicode     = true,
    linktoc     = section,
    pdflang     = fr-FR,
    pdfauthor   = {\@author},
    pdfkeywords = {\@keywords},
    pdftitle    = {\@title},
    pdfsubject  = {...}
}
\makeatother
