Highlighting specific entries in the bibliography using `biblatex`

Question

In a previous topic (Highlighting particular bibliography entries), the asker was looking for a way to color specific entries.

The solution provided allows for choosing arbitrary color for any desired bibliographic entry using \DeclareBibliographyCategory and \AtEveryBibitem. The entry that we want to be colored may explcictly be specified using \addtocategory The result is something as follows

I want to apply very similar thing except thing that I do not want to specify the color of a bibliographic entry. Instead, I want the entire entry to be highlighted with a specific color

Answer 1

I it is possible to get soul's highlighter commands working in a biblatex bibliography. soul and ulem are quite restricted in what they can accept as arguments. The code they would get as argument if we managed to pass the whole bibliography entry as an argument to those commands (which is already a non-trivial task), would not be of a form these commands can work with successfully.

With BibTeX your chances are better, because there the bibliography items are basically normal text that is ready to typeset.

See also How to underline whole bibitem in biblatex?. Since that answer was written, Marcel Krüger has released the package lua-ul (cf. for example https://tex.stackexchange.com/a/446488/35864), which makes it easy to reproduce the behaviour of soul's \hl with LuaLaTeX.

The following MWE, which must be run with LuaLaTeX, produces

\documentclass{article}
\usepackage[x11names]{xcolor}
\usepackage[style=alphabetic]{biblatex}
\usepackage{luacolor,lua-ul}
\usepackage[colorlinks]{hyperref}

\DeclareBibliographyCategory{highlight}

\makeatletter
% This relies on the internal definition of \highLight
% in lua-ul.
% It might be safer to define a new \newunderlinetype ourselves.
\newcommand*{\beginHighLight}[1][\luaul@highlight@color]{%
  \luaul@setcolor{#1}%
  \@highLight}
\makeatother

\AtEveryBibitem{%
  \ifcategory{highlight}%
    {\beginHighLight}%
    {}%
}
