Class moderncv with German bibliography without numbered bibitems

Question

With documentclass moderncv one can include a list of published papers. If you try this is German one could use bibliography style gerplain getting some errors (solved in question Problem with modernCV and bf inside bibliography) but with a missing "und" (German and) or ";" as usual in Germany. (You can try with the following MWE.)

With the styles plaindin or unsrtdin one gets the right bibliography, but now you have leading bibitems [1], [2] etc.

Is there a way to get rid of these bibitems without creating a new bst file? Or to have the bibitems right justified?

The MWE for testing:

\listfiles
\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@BOOK{book1,
  author    = {John Doe and John Smith},
  title     = {Title},
  publisher = {Publisher},
  edition   = {edition},
  year      = {year},
}

@BOOK{book2,
  author    = {John Doe and Eva Smith},
  title     = {Title2},
  publisher = {Publisher2},
  edition   = {edition},
  year      = {year},
}

@MISC{misc1,
  author = {John Doe},
  title  = {Title},
  year   = {year},
}

@MISC{misc2,
  author = {John Doe and Max Musterfrau},
  title  = {Title},
  year   = {year},
}
\end{filecontents*}

                             % plaindin, unsrtdin: unwanted bibitems

I used image example-image-a from package MWE for the photo. You will get a result like:

[1]          Doe, John ; Smith, John: Title. edition. Publisher, year

I would prefer to have:

             Doe, John ; Smith, John: Title. edition. Publisher, year

or (second choise):

        [1]  Doe, John ; Smith, John: Title. edition. Publisher, year

In the resulting bbl file you can find:

\bibitem[1]{book1}
\textsc{Doe}, John ; \textsc{Smith}, John:
\newblock \emph{Title}.
\newblock edition.
\newblock Publisher, year

Using biblatex is not possible because class moderncv is not compatible with it as I know.

Answer 1

The first optional argument of the command \bibitem is executing by the command \@biblabel which have one mandatory argument.

My suggestion uses commands with @ and so you must handle them as describe in the question: What do \makeatletter and \makeatother do?

For the first choice you can gobble the mandatory argument by the following assignment:

 \let\@biblabel\@gobble

For the second choice you can use a small trick. The justification of the bibliography label is done by \@biblabel{#1}\hfill. To gobble the \hfill to get your requested alignment you can use \hfill as part of the definition of \@biblabel

\def\@biblabel#1\hfill{[#1]}

In the mwe below I have implemented both solutions:

\listfiles
\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@BOOK{book1,
  author    = {John Doe and John Smith},
  title     = {Title},
  publisher = {Publisher},
  edition   = {edition},
  year      = {year},
}

@BOOK{book2,
  author    = {John Doe and Eva Smith},
  title     = {Title2},
  publisher = {Publisher2},
  edition   = {edition},
  year      = {year},
}

@MISC{misc1,
  author = {John Doe},
  title  = {Title},
  year   = {year},
}

@MISC{misc2,
  author = {John Doe and Max Musterfrau},
  title  = {Title},
  year   = {year},
}
\end{filecontents*}
