避免使用未定义年份的 biber 警告

我有一个大bib文件，其中有些条目没有年份。我想避免发出的警告，biber -V 以便我能够将这些条目与真正的警告区分开来。（我并不关心这些条目的出现——它们对我来说看起来不错。）

例如，运行以下命令

\documentclass{article}
\begin{filecontents*}{\jobname.bib}
@Misc{No-date,
    author = {Donald Knuth},
    title = {TeXSuX},
    year = {n.d.},
}

@Misc{Forthcoming,
    author = {Leslie Lamport},
    title = {LaTeX3},
    year = {nodate},
    pubstate = {forthcoming},
}

\end{filecontents*}
\usepackage[style=authoryear-ibid]{biblatex}
\addbibresource{\jobname.bib}

\begin{document}
\nocite{*}
\printbibliography
\end{document}

我进入blg文件：

[126] Utils.pm:164> WARN - year field 'nodate' in entry 'Forthcoming' is not an integer - this will probably not sort properly.
[127] Utils.pm:164> WARN - year field 'n.d.' in entry 'No-date' is not an integer - this will probably not sort properly.

省略字段year仍会返回错误。我注意到biblatex手册在第 4.9.2.14 节中考虑了一种nodate打印方法，但我不知道如何避免与之相关的警告。

使用开发版本 Biber 2.8，您可以避免sortyear此警告：

\documentclass{article}
\usepackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@Misc{No-date,
    author = {Donald Knuth},
    title = {TeXSuX},
    year = {n.d.},
    sortyear = 2017
}

@Misc{Forthcoming,
    author = {Leslie Lamport},
    title = {LaTeX3},
    year = {nodate},
    pubstate = {forthcoming},
    sortyear = 2017
}

\end{filecontents*}
\usepackage[style=authoryear-ibid]{biblatex}
\addbibresource{\jobname.bib}

\begin{document}
\nocite{*}
\printbibliography
\end{document}
