Várias caixas com muitas linhas em uma linha com quebra automática ao transbordar

Question

Eu gostaria de ter várias caixas com muitas linhas em uma linha com quebra automática quando as caixas estiverem transbordando.

A ideia seria construir um ambiente personalizado de contribuidores/revisores que eu também possa usar com o TeX4ht:

\documentclass[a4paper]{report}

\usepackage{pgffor}

\newcommand{\ccReviewer}[1]{%
    \hbox{#1}
}
\newcommand{\ccAffiliation}[1]{%
    \hbox{#1}
}
\newcommand{\ccReviewersList}[1]{%
    \hbox{%
        \foreach \reviewer / \affiliation in #1{%
            \vbox{
                \ccReviewer{\reviewer}%
                \ccAffiliation{\affiliation}
            }
        }
    }
}


\begin{document}
\begin{center}
    {\large Contributors and Reviewers}\\
    \vspace{5mm}
    \def\ccReviewers{%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation%
    }
    \ccReviewersList{\ccReviewers}
\end{center}

\end{document}

Aqui está a saída atual:

\documentclass[a4paper]{report}

\usepackage{pgffor,stackengine}

\newcommand{\ccReviewer}[1]{%
    \hbox{#1}
}
\newcommand{\ccAffiliation}[1]{%
    \hbox{#1}
}
\newcommand{\ccReviewersList}[1]{%
        \foreach \reviewer / \affiliation in #1{%
            \Longstack[l]{%
                \ccReviewer{\reviewer}
                \ccAffiliation{\affiliation}
            }
        }
}
\begin{document}
\begin{center}
    {\large Contributors and Reviewers}\\
    \vspace{5mm}
    \def\ccReviewers{%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation%
    }
    \ccReviewersList{\ccReviewers}
\end{center}
\end{document}

Você poderia simplificá-lo ainda mais:

\documentclass[a4paper]{report}

\usepackage{pgffor,stackengine}

\newcommand{\ccReviewersList}[1]{%
    \foreach \reviewer / \affiliation in #1{%
        \addstackgap[4pt]{\Longstack[l]{\reviewer{} \affiliation}}\hspace{4pt} 
    }
}
\begin{document}
\begin{center}
    {\large Contributors and Reviewers}\\
    \vspace{5mm}
    \def\ccReviewers{%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation,%
        Author/Affiliation%
    }
    \ccReviewersList{\ccReviewers}
\end{center}
\end{document}

...ou até mesmo substituir pgfforpor listofitems, como tal, permitindo que você não exija os %trailers da \ccReviewerslista:

\documentclass[a4paper]{report}

\usepackage{stackengine,listofitems}

\newcommand{\ccReviewersList}[1]{%
    \setsepchar[?]{,?/}%
    \readlist*\authlist{#1}%
    \foreachitem\x\in\authlist[]{%
        \addstackgap[4pt]{%
        \Longstack[l]{\authlist[\xcnt,1] \authlist[\xcnt,2]}}\hspace{4pt}
    }
}
\begin{document}
\begin{center}
    {\large Contributors and Reviewers}\\
    \vspace{5mm}
    \def\ccReviewers{
        Author/Affiliation,
        Author/Affiliation,
        Author/Affiliation,
        Author/Affiliation,
        Author/Affiliation,
        Author/Affiliation,
        Author/Affiliation,
        Author/Affiliation,
        Author/Affiliation,
        Author/Affiliation,
        Author/Affiliation
    }
    \ccReviewersList{\ccReviewers}
\end{center}
\end{document}
