首字母缩略词包生成的脚注大写

Question

当acronym包创建脚注时，它会插入acro宏提供的首字母缩略词的定义。我对是否将定义大写存在争议，请参阅 MWE。

\documentclass{article}
\usepackage[footnote]{acronym}
\usepackage{a4wide}

\title{Capitalization issues}
\author{Dohn Joe}

\begin{document}
\maketitle

\section*{My problem}

I would like the long form of the acronyms to be in lower case, since this 
supports the use of the \verb+\acl+ macro. However, footnotes\footnote{Like 
this example.} should start with a capital letter. \\[3ex]
%
Is there a way to enforce the capitalization of the first letter in a 
footnote?\\[5ex]
%
A sentence containing \ac{CCM} and \acl{CCM}. \\[3ex]
%
Another sentence containing \ac{CFD} and \acl{CFD}.

\section*{Acronyms}
\begin{acronym}
    \acro{CCM}{Computational continuum mechanics}
    \acro{CFD}{computational fluid dynamics}
\end{acronym}
\end{document}

Answer 1

您可以修补该命令\@acf。它有一行

\footnote{\AC@placelabel{#1}\AC@acl{#1}{}}

可以改成

\footnote{\AC@placelabel{#1}\@firstupper{\AC@acl{#1}}{}}

该命令\@firstupper由包定义acronym。可以使用 来进行etoolbox修补\patchcmd。

A sentence containing \ac{CCM} and \acl{CCM}.

Another sentence containing \ac{CFD} and \acl{CFD}.
