несколько авторов (имен) \textcites как притяжательные

Question

Расширяя предыдущие ответы наИмя автора \textcite как притяжательное, интересно, как адаптировать предлагаемый код так, чтобы ЕСЛИ поле автора предпоследней цитируемой записи содержит несколько имен, то последующее «и» (для разделения различных записей) заменялось «красиво» на, например, «а также».

\begin{filecontents*}{database.bib}
    @book{texbook,
    author  = {Donald E. Knuth and Someone Else},
    title   = {The {{\TeX}book}},
    publisher   = {Addison-Wesley},
    date    = {1984}
    }

    @inproceedings{foo,
      author = {Foo Bar and {Yet Another} Person},
      title = {Some article},
      abstract = {Here is the abstract.},
      crossref = {acl2015},
      year = {2015}
    }
\end{filecontents*}

и в текстовом файле я хотел бы использовать

\posscites{foo}{texbook}

и это должно быть напечатано как

 Knuth and Else's (1984) as well as Bar and Person's (2015)

Не совсем минимальный MWE следует

I would like the final case, #, to result in:
Bertram and Wentworth’s (e.g. 1996, 4), Aristotle’s (1968) \textbf{as well as} Bertram, Wentworth and Winner’s (2088, 55).  

That is, for the case of british english.

Answer 1

Все, что вам нужно сделать, это добавить aswellasстроку библиографии (с определениями), а затем изменить определение на , \textcitedelimчтобы использовать aswellasвместо andразделителя перед окончательной цитатой, если в окончательной цитате содержится более одного имени.

Добавьте это к преамбуле вашего MWE выше:

\NewBibliographyString{aswellas}
\DefineBibliographyStrings{english}{%
  aswellas = {as well as}
}
\DefineBibliographyStrings{ngerman}{%
  aswellas = {sowei}
}
\renewcommand*{\textcitedelim}{%
  \iffinalcitedelim
    {\ifnumgreater{\value{textcitetotal}}{2}
       {\iftextcitepunct{\finalandsemicolon}{\finalandcomma}}{}%
     \addspace
     \ifnumgreater{\value{labelname}}{1}
       {\bibstring{aswellas}}
       {\bibstring{and}}}
    {\iftextcitepunct{\addsemicolon}{\addcomma}}%
  \space}
