抑制 \unspace 命令以强制 biblatex 添加空格（DIN 1505）

Question

DIN 1505 要求标点符号前有可拆分的单词间空格。参考书目条目应如下所示：

Lastname1, Firstname1 ; Lastname2, Firstname2: Title : Subtitle [...]

                                     ^                                                    ^

我尝试通过重新定义\multinamedelim和\subtitlepunct命令来实现这一点。不幸的是，分别\addspace前面的不会显示在结果文件中。原因是命令删除了前面的空格。它由隐式执行。\addsemicolon\addcolon\unspace\addspace

\addbibresource{test.bib}

\begin{filecontents}{test.bib}
@BOOK{Author2001,
  author = {Alastname, Afirstname},
  title = {Title},
    subtitle = {Subtitle},
  year = {2001},

我找到了一个 DIN 1505 样式的例子（看这里)。作者\addspace用代替\mbox{ }。不幸的是 不正式支持biblatex。有人知道更好的解决方案吗？

Answer 1

您可以分别用普通的或替换\addsemicolon/等命令，这样就变成了。这样就不会检查标点符号前面的空格，但也不会像以前那样检查前面的标点符号。\addcolon;:\DeclareDelimFormat{multinamedelim}{\addspace\addsemicolon\addspace}\DeclareDelimFormat{multinamedelim}{\addspace;\addspace}biblatex\addsemicolon

我们还可以更深入地研究 的内部结构biblatex，并尝试定义我们自己的空间保留宏\addsp<punct>。这些宏是通过 定义的，它本质上是带有注释掉的\blx@addsppunct宏。\blx@addpunct\unspace

现在，当您不希望前面的空格消失时，可以使用\addspsemicolonand\addspcolon代替\addsemicolonand 。\addcolon
