引用のハイパーリンクに年だけでなく著者名も含めたいので、 で始まる行の後に\hypersetup次のコードを使用します。答えただし、これを行うとエラーが発生します: Undefined control sequence。

問題はコードのこの部分にある可能性があります:

\xpatchbibmacro{textcite}
    {\printnames{labelname}}
    {\iflinkparens
        {\DeclareFieldAlias{bibhyperref}{default}%
        \global\booltrue{cbx:link}\biblinkstart%
        \printnames{labelname}}
        {\printtext[bibhyperref]{\printnames{labelname}}}}{}{}

これを削除するとエラーは解消されますが、著者と年の両方にハイパーリンクを設定するという望ましい結果は得られません。

答え1

コードの問題部分を

\xpatchbibmacro{textcite}
{\printnames{labelname}}
{\printtext[bibhyperref]{\printnames{labelname}}}{}{}

クリック可能な著者名と年が表示されます。その間のスペースと括弧だけがクリックできません。これでクリック可能性は十分でしょうか?
