ulem 和 soul 包中没有自动换行

Question

在下面的代码中，我定义了两个命令\refpage并\refpages依次使用ulem和soul 包，但是当句子超出行尾时，它们都不会中断句子。

    \documentclass{book}
    \usepackage{xcolor}
    \usepackage{ulem}
    \usepackage{soul}
    \usepackage{fontspec}
    
    \newcommand\refpage[1]{\textcolor[RGB]{18,93,153}{\bfseries\uline{#1}}}
    
    \newcommand\refpages[1]{\textcolor[RGB]{18,93,153}{\bfseries\ul{#1}}}
    
    \begin{document}
    
    Maple provides an interactive problem-solving environment,
    complete with procedures for performing symbolic,
    numeric, and graphical computations. For more information
    on the toolbar icons, refer to the \refpage{worksheet/reference/WorksheetToolbar}
    help page. At the core of the Maple computer algebra system is a powerful
    programming language. For more information on clearing the Maple internal
    memory and command, refer to the restart help page.

Answer 1

这里有解决方案：(a) 允许在字符串中任意换行；(b) 为字符串添加颜色和粗体。不过我不知道如何添加下划线部分。

% !TEX TS-program = lualatex
\documentclass{book}
\usepackage{fontspec,xcolor}
\usepackage{xurl}
\urlstyle{same}
\usepackage[colorlinks,allcolors=blue]{hyperref} % for \nolinkurl macro

\newcommand\cmdA[1]{\nolinkurl{#1}} % line-breaking
\newcommand\cmdB[1]{\textcolor{red}{\cmdA{#1}}} % coloring and line-breaking
\newcommand\cmdC[1]{\textbf{\cmdB{#1}}} % boldfacing, coloring, and line-breaking
