包含编辑器的条目的自定义 bib 样式

Question

由于我们决定使用来keyword决定是否显示“letzter Zugriff”或“Download am”，因此整个过程并不太复杂。我们还将了解如何使用字段来执行此操作options，而不是使用旧的keywords。

首先，我们需要定义一个新的书目字符串

\NewBibliographyString{downloadon}

然后，我们定义字符串，让它们表达正确的内容

\DefineBibliographyStrings{german}{%
  urlfrom    = {verfügbar unter},
  urlseen    = {letzter Zugriff},
  downloadon = {Download am},
}

url然后我们改变和字段的格式urldate来使用新的字符串，keywords我们需要

\DeclareFieldFormat{url}{\bibstring{urlfrom}\addcolon\space\url{#1}}
\DeclareFieldFormat{urldate}{%
  \mkbibparens{%
    \ifkeyword{pdf}
      {\bibstring{downloadon}}
      {\bibstring{urlseen}}%
    \addcolon\space#1}}

urldate根据关键字是否 pdf存在，显示不同的 bibstring。

或者，我们可以使用options提供给条目。然后我们需要

\newtoggle{blx:pdf}
\DeclareEntryOption{pdf}[true]{%
  \settoggle{blx:pdf}{#1}}

\DeclareFieldFormat{url}{\bibstring{urlfrom}\addcolon\space\url{#1}}
\DeclareFieldFormat{urldate}{%
  \mkbibparens{%
    \iftoggle{blx:pdf}
      {\bibstring{downloadon}}
      {\bibstring{urlseen}}%
    \addcolon\space#1}}

而且您需要添加options = {pdf},到 bib 条目而不是添加keyword pdf。

我们甚至可以稍微自动化一下这个过程，这样所有以结尾的 URL 都会.pdf自动触发该pdf=true选项

\DeclareSourcemap{
  \maps[datatype=bibtex]{
    \map[overwrite]{
      \step[fieldsource=url, match=\regexp{\.pdf\Z}, final]
      \step[fieldset=options, append, fieldvalue={,pdf=true}]
    }
  }
}
