我有一段代码，每次\AddAuthor调用时都会以粗体列出作者，并以斜体列出他们的所属机构，并将所有作者发送到目录。
\newcommand{\AddAuthor}[2]{} %container
\newcommand{\ListAuthor}[1]{
\renewcommand{\AddAuthor}[2]{##1}
\addtocontents{toc}{\quad#1\par}
\renewcommand{\AddAuthor}[2]{
\textbf{##1} \\
\textit{##2} \\
}
}
但是，我希望目录中的作者格式正确，除最后一个作者外，其他作者之间用逗号分隔。如您所见，此代码仅发送以空格分隔的作者。我想可以通过使用计数器并设置条件来实现这一点，但到目前为止我还没有成功。
这是我迄今为止所做的 MWE。
\documentclass[oneside]{book}
\newcommand{\AddAuthor}[2]{} %container
\newcommand{\ListAuthor}[1]{
\renewcommand{\AddAuthor}[2]{##1}
\addtocontents{toc}{\quad#1\par}
\renewcommand{\AddAuthor}[2]{
\textbf{##1} \\
\textit{##2} \\
}
\vspace{-5ex}
#1
\vspace{5ex}
}
\begin{document}
\frontmatter
\tableofcontents
\mainmatter
\chapter{The Awesome Chapter}
\ListAuthor{
\AddAuthor{First Author}{Goodest Boy}
\AddAuthor{Second Author}{Not the Best One}
}
\chapter{The Awesome Chapter, part 2}
\ListAuthor{
\AddAuthor{First Author}{Another Good Boy}
\AddAuthor{Second Author}{The Best of Its Kind}
\AddAuthor{Third Author}{The Baddie}
}
\end{document}
答案1
我不明白为什么你不想用逗号分隔最后一位作者。应该如何分隔？？？这是一个解决方案，所有作者之间都用逗号分隔：
\documentclass[oneside]{book}
\newcommand{\AddAuthor}[2]{%
\textbf{#1} \\
\textit{#2} \\
}
\newcommand{\ListAuthor}[1]{% <-- to avoid potentially unwanted spaces
\begingroup
\def\AddAuthor{\string\AddAuthor}% local redefinition to write \AddAuthor commands to the toc
\addtocontents{toc}{\begin{l@listauthors}#1\end{l@listauthors}}% write l@listauthor environment with all the \AddAuthor commands to the toc
\endgroup
\vspace{-5ex}
\begin{flushleft}
#1
\end{flushleft}
\vspace{5ex}
}
\newif\iffirstauthor% new boolean to detect the first \AddAuthor inside the toc
\newenvironment{l@listauthors}{% environment to be used inside the toc for encapsulating the \AddAuthor commands.
\quad
\firstauthortrue
\renewcommand{\AddAuthor}[2]{% local redefinition of \AddAuthor inside l@listauthors environment (used inside the toc)
\iffirstauthor\firstauthorfalse\else, \fi% if it is the first author set boolean to false otherwise add a comma
##1% output author name
}%
}{\par}
\begin{document}
\frontmatter
\tableofcontents
\mainmatter
\chapter{The Awesome Chapter}
\ListAuthor{%
\AddAuthor{First Author}{Goodest Boy}%
\AddAuthor{Second Author}{Not the Best One}%
}
\chapter{The Awesome Chapter, part 2}
\ListAuthor{%
\AddAuthor{First Author}{Another Good Boy}%
\AddAuthor{Second Author}{The Best of Its Kind}%
\AddAuthor{Third Author}{The Baddie}%
}
\end{document}
这是, and最后一个。
\documentclass[oneside]{book}
\newcommand{\AddAuthor}[2]{%
\textbf{#1} \\
\textit{#2} \\
}
\newcommand{\ListAuthor}[1]{% <-- to avoid potentially unwanted spaces
\begingroup
\def\AddAuthor{\string\AddAuthor}% same as above
\addtocontents{toc}{\begin{l@listauthors}#1\end{l@listauthors}% same as above
}%
\endgroup
\vspace{-5ex}
\begin{flushleft}
#1
\end{flushleft}
\vspace{5ex}
}
\newcounter{authorcnt}% used for the number of authors
\newcounter{lastauthor}% number of last author in the end code of l@listauthors
\newcommand*{\authorlist}{}% used for the local author list of a l@listauthors environment
\newenvironment{l@listauthors}{%
\quad
\setcounter{authorcnt}{0}% init the number to none
\def\authorlist{}% empty the local list (should not be needed)
\renewcommand{\AddAuthor}[2]{%
\stepcounter{authorcnt}% we have one more author
\expandafter\def\expandafter\authorlist\expandafter{% define the author list
\authorlist% by the current list
\stepcounter{authorcnt}% and if the current number
\ifnum\value{authorcnt}>1 , % is > 1 by a comma
\ifnum \value{authorcnt}=\value{lastauthor} and \fi% and if the current number is the last by "and" + space
\fi
##1% and always by the author name
}%
}
}{%
\setcounter{lastauthor}{\value{authorcnt}}%
\setcounter{authorcnt}{0}% start the output again with author number 0
\authorlist
\par
}
\begin{document}
\frontmatter
\tableofcontents
\mainmatter
\chapter{The Awesome Chapter}
\ListAuthor{%
\AddAuthor{First Author}{Goodest Boy}%
\AddAuthor{Second Author}{Not the Best One}%
}
\chapter{The Awesome Chapter, part 2}
\ListAuthor{%
\AddAuthor{First Author}{Another Good Boy}%
\AddAuthor{Second Author}{The Best of Its Kind}%
\AddAuthor{Third Author}{The Baddie}%
}
\end{document}
最后但并非最不重要的一个解决方案是，仅对两个作者and使用而不使用逗号：
\documentclass[oneside]{book}
\newcommand{\AddAuthor}[2]{%
\textbf{#1} \\
\textit{#2} \\
}
\newcommand{\ListAuthor}[1]{% <-- to avoid potentially unwanted spaces
\begingroup
\def\AddAuthor{\string\AddAuthor}%
\addtocontents{toc}{\begin{l@listauthors}#1\end{l@listauthors}}
\endgroup
\vspace{-5ex}
\begin{flushleft}
#1
\end{flushleft}
\vspace{5ex}
}
% This is almost the same as above, only the conditionals are changed
\newcounter{authorcnt}
\newcounter{lastauthor}
\newcommand*{\authorlist}{}
\newenvironment{l@listauthors}{%
\quad
\setcounter{authorcnt}{0}%
\def\authorlist{}%
\renewcommand{\AddAuthor}[2]{%
\stepcounter{authorcnt}%
\expandafter\def\expandafter\authorlist\expandafter{%
\authorlist
\stepcounter{authorcnt}%
\ifnum\value{authorcnt}>1 % for more than one authors add a separator
\ifnum \value{authorcnt}=\value{lastauthor}% before the last author
\ifnum \value{authorcnt}>2
, and % and this, if they are more than 2
\else
\ and % and this, if less than two
\fi
\else , \fi% before all other authors only a comma
\fi
##1%
}%
}
}{%
\setcounter{lastauthor}{\value{authorcnt}}%
\setcounter{authorcnt}{0}%
\authorlist
\par
}
\begin{document}
\frontmatter
\tableofcontents
\mainmatter
\chapter{The Awesome Chapter}
\ListAuthor{%
\AddAuthor{First Author}{Goodest Boy}%
\AddAuthor{Second Author}{Not the Best One}%
}
\chapter{The Awesome Chapter, part 2}
\ListAuthor{%
\AddAuthor{First Author}{Another Good Boy}%
\AddAuthor{Second Author}{The Best of Its Kind}%
\AddAuthor{Third Author}{The Baddie}%
}
\end{document}
