在环境内排版命令，就像它们在环境之外一样

在环境内排版命令，就像它们在环境之外一样

我尝试\dialog[]{}{}在环境中使用自定义命令verse并执行它，“就好像”该命令在环境之外一样。

简而言之，我想让命令不受其所调用的环境的影响。

以下是并非如此MWE，我在其中定义了新的命令\dialog和change margin环境，这是一次粗略的尝试，试图重置边距，但没有成功。

首先，我调用\dialog命令来提供其正常输出的示例，然后在诗歌环境中调用它，最后我将歌词分成两个诗歌环境来展示所需的输出。

我想获得最后的输出，但使用第一个代码语法

\usepackage{extramarks}
\usepackage{needspace}
\usepackage{verse}

%   \renewcommand\linenumberfont{\normalfont\footnotesize\sffamily}

\parindent 0pt
\parskip 0pt
\newlength{\doublespacelength}
\setlength{\doublespacelength}{1.6ex}

\newcommand{\doublespace}{\vspace{\doublespacelength}}

\newenvironment{changemargin}[2]{%
    \begin{list}{}{%
        \setlength{\partopsep}{0pt}%
        \setlength{\topsep}{0pt}%
        \setlength{\leftmargin}{#1}%

        }%
    \end{changemargin}%
  \extramarks{}{}%

答案1

不确定这还会破坏什么。我做了 3 件事：

  1. 我修改\verse并\endverse定义了一个宏\verseskip，在一个组内，

  2. 我改变了\parsep内部\changemargin，并且

  3. 我做了\leftskip\verseskip两次changemargin。

附言：如果我有强迫症，我会把“a MWE”改成“an MWE”。

答案2

部分解决方法是创建两个版本的 \dialog 命令，一个用于在内部执行，一个用于在 verse 环境之外执行。我不会将此标记为答案然而原因有二：

  • 我并没有“好像”在诗歌环境中执行 \dialog 命令，实际上我关闭了环境，执行了命令并重新打开了环境，在我看来这是一个不雅的操作。
  • 即使新命令 \dialog 在诗句环境内外是相同的，诗句环境“内部”的 \dialog 输出的第二行也以某种方式缩进。我现在还不知道为什么该行缩进，需要进一步检查。

以下是 MWE 的概要：

\documentclass{article}

\usepackage{ifthen}
\usepackage{verse}

\newcommand{\dialog}[3][]{%
         \textsc{#2} \ifthenelse{\equal{#1}{}}{}{(\textit{#1})}%
         \par%
\texttt{#3}%
}

\def \dout{\dialog[scioccata]{Nena}{La cioccolata fa schifo!}}
\def \din{\end{verse}\dialog[scioccata]{Nena}{La cioccolata fa schifo!}\begin{verse}[\versewidth]}

\makeatletter
    \newcommand{\currentEnv}{%
     \ifthenelse{\equal{\@currenvir}{verse}}{\din}{\dout}%
    }
\makeatother



\begin{document}

\dout

\settowidth{\versewidth}{E’ una storia triste}
\begin{verse}[\versewidth]
    trallalero\\
    \currentEnv
    trallallà
\end{verse}

\end{document}
