Biber Hyphenated Authors

Question

I have two bibLaTex entry

@article{madeUp1,
  title = {MadeUPTitle},
  author = {MadeUp Author1 and MadeUp Author2 and MadeUp Author3 and MadeUp Author4},
  journal = {MadeUpJournal},
  volume = {0},
  issue = {0},
  pages = {000--001},
  numpages = {0},
  year = {2021},
  month = {April},
  publisher = {MadeUpPublisher},
  doi = {www.madeup.com/21321},
}

and

@article{madeUp2,
  title = {MadeUPTitle},
  author = {Author1, Madeup and Author2, Madeup and Author3, Madeup and Author4, Madeup},
  journal = {MadeUpJournal},
  volume = {0},
  issue = {0},
  pages = {000--001},
  numpages = {0},
  year = {2021},
  month = {April},
  publisher = {MadeUpPublisher},
  doi = {www.madeup.com/21321},
}.

I used biber with this style

\usepackage[backend=biber,style=alphabetic,sorting=nyt]{biblatex}.

Therefore, when I use \citeauthor{madeUp1} I get result "MadeUp Author1 and MadeUp Author2 and MadeUp Author3 and MadeUp Author4", which is what I want. However, I would like a command \citeauthorhyphenated to render only the surnames of the authors separated by the proper dash like

"Author1--Author2--Author3--Author4"

when I type \citeauthorhyphenated{madeup1}. Also it should render the same thing with \citeauthorhyphenated{madeUp2}. A search online does not render any results and hence I am stuck...

Answer 1

Funnily enough, there was a related question not too long ago (Biblatex - hyphen between author names when using citet), we can use the methods explained there. One easy solution is to pack \AtNextCite with suitable \DeclareDelimFormat definitions together with \citeauthor into a new command.

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage{babel}
\usepackage{csquotes}
\usepackage[backend=biber, style=alphabetic, sorting=nyt, maxcitenames=999]{biblatex}

\makeatletter
\newcommand*{\citeauthorattr}{%
  \AtNextCite{%
    \DeclareDelimFormat{multinamedelim}{\textendash\penalty\hyphenpenalty}%
    \DeclareDelimAlias{finalnamedelim}{multinamedelim}%
  }%
  \citeauthor}
\makeatother
