格式化参考书目中虚线条目后的句号和大写字母

Question

考虑以下 MWE。

\documentclass{article}

\usepackage{fontspec}
\setmainfont{EB Garamond}

\usepackage[style = authoryear-comp]{biblatex}
\usepackage{xpatch}
    \xpatchbibmacro{date+extradate}{\printtext[parens]}{\setunit*{\addperiod\space}\printtext}{}{} % remove parenthesis around year in bibliography
\DeclareFieldFormat{editortype}{\mkbibparens{#1}} % put editor in parenthesis when before publication year
\DeclareDelimFormat{editortypedelim}{\addspace}
%\renewcommand*\bibnamedash{\char"2E3B\addperiod\space} % use a 3em dash with period after it for dashed author names

\begin{filecontents}[overwrite]{\jobname.bib}
@book{anderson1980,
    AUTHOR = "Peter Anderson",
    TITLE = "My book",
    YEAR = "1980"}
@book{anderson1981,
    AUTHOR = "Peter Anderson",
    TITLE = "My second book",
    YEAR = "1981"}
@collection{anderson1982,
    EDITOR = "Peter Anderson",
    TITLE = "Interesting articles",
    YEAR = "1982"}
@collection{smith1983,
    EDITOR = "Harry Smith",
    TITLE = "Good chapters",
    YEAR = "1983"}
\end{filecontents}
\addbibresource{\jobname.bib}

\begin{document}

\nocite{anderson1980}\nocite{anderson1981}\nocite{anderson1982}\nocite{smith1983}

\printbibliography
\end{document}

输出看起来还不错：

但我想遵循 Bringhurst 的建议，使用三个破折号。此外，破折号只能替代名称，而不能替代标点符号，因此破折号后面应该跟一个句号。取消注释 MWE 中注释的行将得到以下内容：

虽然此处的第二条记录看起来正确，但第三条记录却不正确。破折号和括号之间不应该有句号(Ed.)，因为这里一开始就没有句号，如第四条也是最后一条记录所示。其次，括号中的单词的首字母不应该大写（此处之所以大写是因为前面有句号，所以一旦删除句号，它可能会自行消失）。

简而言之，第三行应该是--- (ed.). 1982.，而不是---. (Ed.). 1982。如何才能实现这一点，同时又不从第二个条目中删除句点？

默认情况下，biblatex标准样式会打印\bibnamedashnot in\printtext或任何其他尊重标点符号缓冲区的命令。这让事情变得有点混乱。

我建议您修改相关的宏以\bibnamedash在内部打印\printtext，以便标点符号缓冲区可以实际使用。我们还重新定义了这些宏，以便它们始终打印editortypedelim/translatortypedelim标点符号。然后，\printtext{\bibnamedash}其行为与这些宏中的和朋友完全类似\printnames{author}。（如果您想将新宏与原始定义进行比较，可以在以下位置找到相关宏authoryear.bbx[版本 3.17 中第 202-268 行]。

然后只需设置\bibnamedeash为\char"2E3B（无需额外的标点符号）并打印所需的内容nameyeardelim。

请注意，我删除了xpatch而采用了biblatex-ext的biblabeldate字段格式。请参阅我的答案到如何（正确地）删除 authoryear 样式中年份周围的括号？（v3）。
