cite コマンドに翻訳者情報を追加する

Question

翻訳者情報を cite コマンドに追加しようとしています (参考文献自体のニーズに合わせて既に修正しています)。

出版物に著者や編集者がいない場合は、翻訳者が引用元に印刷されますが、これは正しいです。さらに、翻訳者であるという情報を追加したいと思います。（私はドイツ語を使用しているので、翻訳者情報はドイツ語で印刷されますÜbers.）例：

対象textcite：Lastname (Übers.) (2010: 1-2)

対象parencite：（姓（Übers.）2010：1-2）

参考文献の例:

@incollection{Kern.2010-EarlyChineseLiterature,
    translator = {Kern, Martin},
    booktitle = {The Cambridge History of Chinese Literature},
    date = {2010-04-01},
    isbn = {978-1-139-09541-9},
    pages = {1--115},
    publisher = {Cambridge University Press},
    title = {Early Chinese Literature, Beginnings Through Western Han},
    }

（これは単なる例です）

このアイデアは、BibLaTex - 引用と参考文献のマーク エディター (ラベル名)基本的に、名前のlabelnamesourceタイプ (//) をauthorチェックし、そのジョブに適した bibmacro を使用します。次に、 と を再定義して、拡張された名前を印刷するだけです。editortranslatorcitetetxcite
