禁用 lettrine 命令的功能

Question

我希望我的文档有两个版本。区别取决于是否kpfonts加载。如果未加载，我想禁用该\lettrine命令，并且命令中的参数应显示为普通文本。下面是 MWE。

\documentclass{scrreprt}
\usepackage{lettrine}
\usepackage{lipsum}
%\usepackage{kpfonts}

\makeatletter
\@ifpackageloaded{kpfonts}{%
%don't do anything in this MWE
}
{
\renewcommand{\familydefault}{\sfdefault} %just an example
%I also want to disable lettrine here
}
\makeatother

\begin{document}

\chapter{Whatever}

\lettrine[findent=1pt, nindent=1pt]{N}{ow, let lipsum do the job:} \lipsum[1]

%Now, let lipsum do the job: \lipsum[1]. <<Achieve this with the above line

\end{document}

有没有办法做到这一点，让我不必编辑实际的文本？

Answer 1

添加\renewcommand{\lettrine}[3][]{#2#3}就可以了。

\documentclass{scrreprt}
\usepackage{lettrine}
\usepackage{lipsum}
%\usepackage{kpfonts}

\makeatletter
\@ifpackageloaded{kpfonts}
  {%
   %don't do anything in this MWE
  }
  {%
   \renewcommand{\familydefault}{\sfdefault}%just an example
   \renewcommand{\lettrine}[3][]{#2#3}%
  }
\makeatother

\begin{document}

\chapter{Whatever}

\lettrine[findent=1pt, nindent=1pt]{N}{ow, let lipsum do the job:} \lipsum[1]

Now, let lipsum do the job: \lipsum[1].

\end{document}
