我正在编写一种biblatex扩展另一个第三方样式的样式。我需要的是，\DeclareCiteCommand这样\justcite打印参考书目时就不会考虑它的引用，而只有当作者不再使用任何其他引用命令（例如）引用它时才会考虑\cite。解决方案不应该要求在\printbibliography命令中设置选项，也不应该在条目中设置特殊属性.bib，这意味着所有实现都应该在我的样式文件中。
\DeclareBibliographyCategory{refcite}
\AtEveryCitekey{%
\ifcsstring{blx@delimcontext}{justcite}{}{%
\addtocategory{refcite}{\thefield{entrykey}}}}
\newbibmacro*{justcite}{%
\DeclareFieldAlias{bibhyperref}{noformat}%
\usebibmacro{cite}}
\DeclareCiteCommand{\justcite}
{\usebibmacro{prenote}}
{\usebibmacro{citeindex}%
\usebibmacro{justcite}}
{}
{\usebibmacro{postnote}}
\DeclareMultiCiteCommand{\justcites}
{\justcite}
{\setunit{\multicitedelim}}
但这样作者就需要category在\printbibliography命令中明确设置选项：
\printbibliography[category=refcite]
我还发现了一些有关refsections 的信息，但我不确定我应该如何实现它以及这对我有何帮助。
也许我可以直接在我的样式文件中为命令设置默认选项\printbibliography，但我没有找到有关这种方法的任何文档或实现。
我怎样才能实现这个目标？
以下代码是我当前拥有的 MWE：
\documentclass{article}
\usepackage[style=abnt]{biblatex}
\usepackage[citecolor=red, colorlinks]{hyperref}
\DeclareBibliographyCategory{refcite}
\AtEveryCitekey{%
\ifcsstring{blx@delimcontext}{justcite}{}{%
\addtocategory{refcite}{\thefield{entrykey}}}}
\newbibmacro*{justcite}{%
\DeclareFieldAlias{bibhyperref}{noformat}%
\usebibmacro{cite}}
\DeclareCiteCommand{\justcite}[\mkbibparens]
{\usebibmacro{cite:init}%
\usebibmacro{prenote}}
{\usebibmacro{citeindex}%
\usebibmacro{justcite}}
{}
{\usebibmacro{postnote}}
\DeclareMultiCiteCommand{\justcites}[\mkbibparens]
{\justcite}
{\setunit{\multicitedelim}}
\addbibresource{biblatex-examples.bib}
\begin{document}
This sentence wants to list the reference of its citation because it is important \cite{aksin}.
But not this sentence \justcite{aksin,glashow}. However, once \verb|aksin| was cited above with \verb|\cite|, it appears in the references below.
\printbibliography[category=refcite]
\end{document}
它生成以下文档，其中是预期结果：
请注意，glashow未列出参考文献，因为它仅被命令引用\justcite。
再次，问题在于作者必须category在\printbibliography命令中明确设置选项。但是，当引用条目在参考文献中列出时，引用的处理方式对作者来说应该是隐含的，即，这种过滤应该直接在我的样式文件中实现。
根据 MWE，这意味着作者应该有以下内容：
\documentclass{article}
\usepackage[style=my-style]{biblatex}
\usepackage[citecolor=red, colorlinks]{hyperref}
\addbibresource{biblatex-examples.bib}
\begin{document}
This sentence wants to list the reference of its citation because it is important \cite{aksin}.
But not this sentence \justcite{aksin,glashow}. However, once \verb|aksin| was cited above with \verb|\cite|, it appears in the references below.
\printbibliography
\end{document}
并且此代码应该生成相同的文档。
我还相信一定有一种更通用的方法来解决这个问题，而不需要下面的代码片段：
\AtEveryCitekey{%
\ifcsstring{blx@delimcontext}{justcite}{}{%
\addtocategory{refcite}{\thefield{entrykey}}}}
对我来说这似乎也是一种解决方法。
顺便说一下，MWE 使用了biblatex我想要扩展的样式，该包名为biblatex-abnt。

也许我可以直接在我的样式文件中为命令设置默认选项
\printbibliography，但我没有找到有关这种方法的任何文档或实现。
\DeclarePrintbibliographyDefaults是您要查找的命令。它不需要密钥category，但它确实需要filter密钥，所以我们只需要定义一个仅匹配refcite
类别的过滤器。

\AtEveryCitekey我们可以使用和 书目来确定该条目是否应包含在书目中，而不是定义新的书目类别
check。但是我们无法设置check和
\DeclarePrintbibliographyDefaults，因此我们需要侵入私有 BibLaTeX 宏来执行此操作。
