El subtipo de entrada ya no se considera

Question

Solía ​​usar un subtipo de entrada para article(llamado newspaper), para hacer algunas modificaciones al bibliography, precisamente, quería que el periódico apareciera en cursiva, si no hay autor. Sin embargo, esto parece no tenerse en cuenta al compilar y al principio pensé que se debía a mis estilos de bib personalizados, pero ocurrió el mismo problema cuando los eliminé. (Además, no estoy seguro de por qué se omiten aquí las paréntesis japonesas, pero ese es un problema menor :))

Así es como solía verse (y cómo deseo que se vea):

Así es como se ve ahora: MWE:

Answer 1

En el smallcapsapartado encontramos lo siguiente

% smallcaps
\newtoggle{bbx@journalauthor}
\DeclareEntryOption[boolean]{journalauthor}[true]{%
\settoggle{bbx@journalauthor}{#1}}

\renewcommand{\mkbibnamefamily}[1]{%
  \ifitemannotation{journalauthor}
    {\mkbibemph{#1}}
    {\textsc{#1}}}

\newtoggle{bbx@director}
\DeclareEntryOption[boolean]{director}[true]{%
\settoggle{bbx@director}{#1}}

\renewcommand{\mkbibnamefamily}[1]{%
  \ifitemannotation{director}
    {\mkbibemph{#1}}
    {\textsc{#1}}}

\newtoggle{bbx@producer}
\DeclareEntryOption[boolean]{producer}[true]{%
\settoggle{bbx@producer}{#1}}

\renewcommand{\mkbibnamefamily}[1]{%
  \ifitemannotation{producer}
    {\mkbibemph{#1}}
    {\textsc{#1}}}    

Este código redefine la misma macro \mkbibnamefamilytres veces. Sólo prevalecerá la última redefinición. Si desea que todas esas definiciones se apliquen al mismo tiempo, deberá combinarlas en una sola. Eso podría suceder con \ifboolexpr, que nos permite evaluar expresiones booleanas arbitrarias.

\renewcommand{\mkbibnamefamily}[1]{%
  \ifboolexpr{
       test {\ifitemannotation{journalauthor}}
    or test {\ifitemannotation{director}}
    or test {\ifitemannotation{producer}}}
    {\mkbibemph{#1}}
    {\textsc{#1}}}

Entonces todo el bloque leería

% smallcaps
\newtoggle{bbx@journalauthor}
\newtoggle{bbx@director}
\newtoggle{bbx@producer}

\DeclareEntryOption[boolean]{journalauthor}[true]{%
  \settoggle{bbx@journalauthor}{#1}}
\DeclareEntryOption[boolean]{director}[true]{%
  \settoggle{bbx@director}{#1}}
\DeclareEntryOption[boolean]{producer}[true]{%
  \settoggle{bbx@producer}{#1}}

\renewcommand{\mkbibnamefamily}[1]{%
  \ifboolexpr{
       test {\ifitemannotation{journalauthor}}
    or test {\ifitemannotation{director}}
    or test {\ifitemannotation{producer}}}
    {\mkbibemph{#1}}
    {\textsc{#1}}}

---

Tenga en cuenta que los alternadores bbx@directory bbx@producerestán definidos, pero no se utilizan en ninguna parte del resto del documento. Sólo bbx@journalauthorse utiliza más adelante.

Esto y el resto de tu estilo me hace dudar de que realmentedesearlas definiciones de producery director. Entonces tal vez solo quieras eliminar el código directory producerreemplazar todo el bloque con solo

\newtoggle{bbx@journalauthor}
\DeclareEntryOption[boolean]{journalauthor}[true]{%
  \settoggle{bbx@journalauthor}{#1}}

\renewcommand{\mkbibnamefamily}[1]{%
  \ifitemannotation{journalauthor}
    {\mkbibemph{#1}}
    {\textsc{#1}}}
