在一本有关 R 的书中，我\pkg{}对每次提及 R 包都使用一个命令，该命令还会通过另一个命令生成索引扩展\ixp{}。
\newcommand{\pkg}[1]{\textsf{#1}\ixp{#1}}
所有软件包都有 .bib 条目，我想修改它，以便软件包\cite{}在其第一的使用，但随后会生成一个\nocite{}。也就是说，
\newcommand{\pkg}[1]{\textsf{#1}\ixp{#1} \citep{#1}}
但是，如果 .bib 键参数 ( ) 之前在文本中出现过，则位置\citep{#1}会变成。 (我记得，词汇表包会做类似的事情。) 我该如何修改此定义以实现此行为？\nocite{#1}#1
这里的目标是生成所有软件包的参考文献，但要避免每次提及都引用文本而造成文本混乱。\nocite{}为了在作者索引中生成条目，需要在第一次出现后使用。
以下是 MWE：

答案1
也许你需要这个：
\def\pkg#1{\textsf{#1}\ixp{#1}~\citex{#1}}
\def\citex#1{\expandafter\ifx\csname cit:#1\endcsname\relax
\expandafter\gdef\csname cit:#1\endcsname{}%
\citep{#1}%
\else
\nocite{#1}%
\fi
}
该\citex宏测试该参数是否之前使用过，即控制序列是否\cit:parameter已定义。如果没有，则扩展为\citep{parameter}并定义\cit:parameter。否则扩展为\nocite{parameter}。
答案2
我添加了一个*无论如何都会打印引用的 -variant，它不算作第一个（也许你想在介绍中或文档的后面部分使用它）。

答案3
假设这\nocite不是真正需要的，那么这应该有效：
\newcommand{\expkg|[1]{\textsf{#1}\ixp{#1}}
\newcommand{\pkg}[1]{\textsf{#1}\ixp{#1} \citep{#1}\expkg{#1}}
毕竟，单个条目\cite将在文件中放置一个条目\.aux，告诉 bibtex 识别.bib文件中的匹配条目并在.bbl文件中创建一个等效条目——只需要一个。的通常目的\nocite
是确保项目包含在文件中.bbl（因此包含在参考书目中），如果它是不是文中确实引用了。
答案4
这不是一个直接的答案，但也许你会发现它很有用。这是我编写的一个包，但从未发布过，用于类似但不完全相同的目的。这个包的目的是使编写有关编程语言的文章变得更容易。要引用 Java 等语言，请\Java在输入中写入。它会添加引用，但前提是这是第一次使用该命令。
