修复 natbib 错误（作者？）而不使用预定义的参考书目样式

Question

我想将该natbib命令\citet用于自定义.bst文件。但pdf文件却包含“(authors?)”（请参阅为什么当我将 \citet 与 natbib 一起使用时会得到（作者？）？）。

我怎样才能在不使用预定natbib义样式（如 plainnat）的情况下解决这个问题？

我注意到该aux文件包含一个bibcite如下所示的命令：\bibcite{foo2008}{{Foo~2008}{}{{}}{{}}}。如果我手动编辑此命令，我可以轻松获得与使用预定义样式时类似的结果natbib。

什么负责生成bibcite命令？如何包含更多信息？它是样式文件中的函数吗bst？

我只想编辑我的bst文件。以下是我的文件：

如果要使用带有作者年份引用模块的.bst文件，则该文件需要以可读的方式传递作者和年份信息。这可以通过可选参数来完成。 explain中的注释natbib.bstnatbib\bibitemnatbib.sty

 % This package reimplements the LaTeX \cite command to be used for various
 % citation styles, both author-year and numerical. It accepts BibTeX
 % output intended for many other packages, and therefore acts as a
 % general, all-purpose citation-style interface.
 %
 % With standard numerical .bst files, only numerical citations are
 % possible. With an author-year .bst file, both numerical and
 % author-year citations are possible.
 %
 % If author-year citations are selected, \bibitem must have one of the
 %   following forms:
 %   \bibitem[Jones et al.(1990)]{key}...
 %   \bibitem[Jones et al.(1990)Jones, Baker, and Williams]{key}...
 %   \bibitem[Jones et al., 1990]{key}...
 %   \bibitem[\protect\citeauthoryear{Jones, Baker, and Williams}{Jones
 %       et al.}{1990}]{key}...
 %   \bibitem[\protect\citeauthoryear{Jones et al.}{1990}]{key}...
 %   \bibitem[\protect\astroncite{Jones et al.}{1990}]{key}...
 %   \bibitem[\protect\citename{Jones et al., }1990]{key}...
 %   \harvarditem[Jones et al.]{Jones, Baker, and Williams}{1990}{key}...
 %
 % This is either to be made up manually, or to be generated by an
 % appropriate .bst file with BibTeX.

您的.bst文件在编写时并没有考虑到这个系统（事实上它是在它出现之前编写的natbib），但让它与之配合并不难natbib。

正如您指出的，您的.bst文件会生成以下形式的引用标签

\bibitem[<author>~<year>]

通过两个小改动，我们可以使其生成natbib-兼容的

\bibitem[<author>(<year>)]

只是改变

FUNCTION {calc.label}
{ type$ "book" =
  type$ "inbook" =
  or
    'author.editor.key.label
    { type$ "proceedings" =
    'editor.key.organization.label
    { type$ "manual" =
        'author.key.organization.label
        'author.key.label
      if$
    }
      if$
    }
  if$
  duplicate$
  "~" *
  year #-1 #4 substring$ field.or.null purify$ *
  'label :=
  year #-1 #4 substring$ field.or.null purify$ 
  *
  sortify 'sort.label :=
}

到

FUNCTION {calc.label}
{ type$ "book" =
  type$ "inbook" =
  or
    'author.editor.key.label
    { type$ "proceedings" =
    'editor.key.organization.label
    { type$ "manual" =
        'author.key.organization.label
        'author.key.label
      if$
    }
      if$
    }
  if$
  duplicate$
  "(" *
  year #-1 #4 substring$ field.or.null purify$ *
  ")" *
  'label :=
  year #-1 #4 substring$ field.or.null purify$ 
  *
  sortify 'sort.label :=
}

这些函数之间的实际区别只是
