Allow user to evaluate ExecuteBibliographyOptions in DeclareCiteCommand

[tobiasBora]

I'm trying to redefine fullcite to include doi, giveninits=false... Unfortunately, I can't use \ExecuteBibliographyOptions{style=trad-alpha,doi=false,giveninits=false} inside \DeclareCiteCommand, and I'm forced to dig into the source and type things like \settoggle{abx@bool@giveninits}{false} \settoggle{bbx:doi}{true}, which is really ugly. Also, I can't find how to change the style, I tried \def\blx@opt@eldt@style{ieee} but it does nothing. Similarly, I may also need to change the value of maxnames and many more options.

Note that I may have missed an option, in that case I'm curious to learn about it.

MWE

\documentclass[options]{article}
\usepackage[
 style=trad-alpha,
 doi=false,
 giveninits=true, % Bob Foo --> B. Foo
 isbn=false,
 url=false,
 eprint=false,
 sortcites=false, % \cite{B,A,C}: [A,B,C] --> [B,A,C]
]{biblatex}
\parindent=0pt
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@article{Mer89_WhatWrongThis,
  title = {What's {{Wrong}} with This {{Pillow}}?},
  author = {Mermin, N. David},
  year = {1989},
  month = apr,
  volume = {42},
  pages = {9--11},
  publisher = {{American Institute of Physics}},
  issn = {0031-9228},
  doi = {10.1063/1.2810963},
  journal = {Physics Today},
  number = {4}
}
\end{filecontents}
\addbibresource{\jobname.bib}

\makeatletter
\DeclareCiteCommand{\fullcite}
  {\usebibmacro{prenote}}
  {%
    % Does not work:
    % \ExecuteBibliographyOptions{style=ieee,giveninits=false,doi=true,url=true,eprint=true}
    \def\blx@opt@eldt@style{ieee}% <--- does nothing.
    \settoggle{abx@bool@giveninits}{false}% Fake giveninits=false, but Whoo, looks super dirty
    \settoggle{bbx:doi}{true}% Fake doi=true, but Whoo, looks super dirty
    \settoggle{bbx:url}{true}% Fake url=true, but Whoo, looks super dirty
    \settoggle{bbx:eprint}{true}% Fake url=true, but Whoo, looks super dirty
    \settoggle{bbx:isbn}{true}% Fake url=true, but Whoo, looks super dirty
    \usedriver{}{\thefield{entrytype}}}%
  {\multicitedelim}%
  {\usebibmacro{postnote}}%
\makeatother

\begin{document}

Here I would like the doi, url, isbn, giveninits=false...
\begin{itemize}
\item \fullcite{Mer89_WhatWrongThis}
\end{itemize}

While here, I want short citations, without doi, url, isbn, and with giveninits=true:
\printbibliography

\end{document}

It is an interesting suggestion to allow for (more) local execution of some options. But this definitely cannot work for all options. The style option for example is implemented in such a way that it can only be passed at loading time as it determines which style files are read. You cannot switch the style mid-document, much less mid-command.

At the moment, I see style options as a quick way to set things for end-users. If you begin writing your own commands and heavily modifying existing ones, you are sort of expected to go a bit deeper and implement things on a more basic level.

Imho it would be nice to have some interface for local execution. And to have a list with the options for which such local execution actually works.
