所有格引用创建双倍空间

所有格引用创建双倍空间

当我尝试进行所有格引用时，出于某种原因，引用前的字符之间会创建 2 个空格，而不是 1 个。你知道我该如何解决这个问题吗？（在文本中不写一个空格可能会有点麻烦，因为我必须记住这一点才能进行所有格引用）

答案1

与许多涉及额外空格的问题一样，如果宏定义生成可打印的文本，则需要非常小心，不要在宏定义中的行尾留有空格。行尾被视为空格。因此，您需要删除命令%前两行中注释标记前的空格\DeclareNameFormat：

\DeclareNameFormat{labelname:poss}{% based on labelname from biblatex.def
  \nameparts{#1}% not needed if using Biblatex 3.4

您可能还应该%在此行后面添加：

\ifuseprefix
      {\usebibmacro{name:first-last}{\namepartfamily}{\namepartgiveni}{\namepartprefix}{\namepartsuffixi}}% <--- added

答案2

艾伦·芒恩的回答就文档中虚假空格的来源而言，这是正确的，但我想提供一个略有不同的答案，我们使用新的名称包装器格式来缩短代码。

我们可以避免使用整个\DeclareNameFormat{labelname:poss}代码块，而是有效地用它替换\DeclareNameWrapperFormat{labelname:poss}{#1s}并在以后使用。请注意，在下面的示例中，我使用了略有不同的构造，以使代码更加紧凑。

\documentclass{scrartcl}
\usepackage[main=ngerman, english]{babel}
\usepackage[babel, german=quotes]{csquotes}
\usepackage[
  backend=biber,
  style=ext-authoryear,
]{biblatex}
\usepackage[hidelinks, pdfencoding=auto]{hyperref}

\DeclareDelimFormat[bib]{nametitledelim}{\addcolon\space}

\newrobustcmd*{\posscitealias}{%
  \AtNextCite{%
    \DeclareNameWrapperFormat{labelname}{##1s}%
    \DeclareFieldFormat{label}{##1s}}}
\newrobustcmd*{\posscite}{%
  \posscitealias%
  \textcite}
\newrobustcmd*{\Posscite}{\bibsentence\posscite}
\newrobustcmd*{\posscites}{%
  \posscitealias%
  \textcites}

\begin{filecontents}{\jobname.bib}
@report{Chafe.1974,
  author      = {Chafe, Wallace L.}, 
  title       = {An Approach to Verbalization and Translation by Machine. Final Report}, 
  month       = {10},
  year        = {1974},
