自定义列表中有多行项目？

我有以下用于生成课程提纲日期的自定义列表：

\documentclass{article}
\usepackage{advdate}
\usepackage[dayofweek]{datetime}
\newdateformat{syldate}{\twodigit{\THEMONTH}/\twodigit{\THEDAY}
\,(\shortdayofweekname
{\THEDAY}{\THEMONTH}{\THEYEAR})}
\newenvironment{schedule}
  {\par\syldate\renewcommand{\item}{\par
    \stepcounter{mycntr}\ifnum\value{mycntr}>2\relax
      \setcounter{mycntr}{0}\AdvanceDate[3]
    \else
      \AdvanceDate[2]
    \fi\today\quad}
  }{\par}
\SetDate[01/09/2014]
\newcounter{mycntr}

\begin{document}

\begin{schedule} % My custom environment with problematic behavior

\item Topic \\ Assigned Reading

\item Topic \\ Assigned Reading

\end{schedule}

\begin{itemize} % Desired behavior
    \item Topic \\ Assigned Reading
    \item Topic \\ Assigned Reading
\end{itemize}

\end{document}

每当我尝试将项目的第二部分移到新行时，它都会与项目标签对齐，而不是与项目的第一行对齐。Itemize 默认会执行我想要的操作。如何将这种行为构建到我的自定义列表中？

如果你不打算在“指定阅读材料”中列出清单和段落，你可以选择

\documentclass{article}
\usepackage{advdate}
\usepackage[dayofweek]{datetime}
\newdateformat{syldate}{%
  \twodigit{\THEMONTH}/\twodigit{\THEDAY}%
  \,(\shortdayofweekname
  {\THEDAY}{\THEMONTH}{\THEYEAR})%
}
\newlength{\datelength}
\newenvironment{schedule}
  {\par
   \settowidth{\datelength}{00/00\,(Wed)\quad}%
   \renewcommand{\item}{%
     \par\hangindent=\datelength\noindent
     \stepcounter{mycntr}\ifnum\value{mycntr}>2\relax
       \setcounter{mycntr}{0}\AdvanceDate[3]%
    \else
       \AdvanceDate[2]%
    \fi
    \makebox[\datelength][l]{\today}%
  }%
  \syldate
  }
  {\par}
\SetDate[01/09/2014]
\newcounter{mycntr}

\begin{document}

\begin{schedule} % My custom environment with problematic behavior

\item Topic \\ Assigned Reading

\item Topic \\ Assigned Reading

\item Topic \\ Assigned Reading

\item Topic \\ Assigned Reading

\end{schedule}

\end{document}

然而，更好的实现是enumitem：

\documentclass{article}
\usepackage{showframe} % just for the example
\usepackage{enumitem}
\usepackage{advdate}
\usepackage[dayofweek]{datetime}
\newdateformat{syldate}{%
  \twodigit{\THEMONTH}/\twodigit{\THEDAY}%
  \,(\shortdayofweekname
  {\THEDAY}{\THEMONTH}{\THEYEAR})%
}
\newlength{\datelength}
\newcommand\topic[1]{%
  \stepcounter{mycntr}%
  \ifnum\value{mycntr}>2\relax
    \setcounter{mycntr}{0}\AdvanceDate[3]%
  \else
    \AdvanceDate[2]%
  \fi
  \item[\today]#1\\
}
\newenvironment{schedule}
  {\syldate
   \settowidth{\datelength}{00/00\,(Wed)\quad}%
   \enumerate[leftmargin=\datelength,labelsep=0pt,labelwidth=\datelength,align=left]
  }
  {\endenumerate}
\SetDate[01/09/2014]
\newcounter{mycntr}

\begin{document}

\begin{schedule}

\topic{Topic} Assigned Reading

\topic{Topic} Assigned Reading

\topic{Topic} Assigned Reading

\topic{Topic} Assigned Reading

\end{schedule}

\end{document}

我更喜欢使用\topic命令而不是滥用，\item这样只需根据定义采取行动就可以随意定制主题标题的外观\topic。

垂直间距可通过功能进行自定义enumitem。请注意，showframe此处使用的 仅用于显示文本块边距。

缩进的差异源于第一行缩进是由于\parindent，它不会延续到后续行。将缩进延续到后续行的参数是\leftskip。我会大大重写该方法（也许使用list环境，但为了快速实现您的要求，我只是插入了这一行

\leftskip=\parindent\relax\parindent=0pt\relax

在环境的开头schedule。它的作用是使用当前值\parindent作为\leftskip环境调用的当前值。

\documentclass{article}
\usepackage{advdate}
\usepackage[dayofweek]{datetime}
\newdateformat{syldate}{\twodigit{\THEMONTH}/\twodigit{\THEDAY}
\,(\shortdayofweekname
{\THEDAY}{\THEMONTH}{\THEYEAR})}
\newenvironment{schedule}
  {\leftskip=\parindent\relax\parindent=0pt\relax
    \par\syldate\renewcommand{\item}{\par
    \stepcounter{mycntr}\ifnum\value{mycntr}>2\relax
      \setcounter{mycntr}{0}\AdvanceDate[3]
    \else
      \AdvanceDate[2]
    \fi\today\quad}
  }{\par}
\SetDate[01/09/2014]
\newcounter{mycntr}

\begin{document}

\begin{schedule} % My custom environment with problematic behavior

\item Topic \\ Assigned Reading

\item Topic \\ Assigned Reading

\end{schedule}

\begin{itemize} % Desired behavior
    \item Topic \\ Assigned Reading
    \item Topic \\ Assigned Reading
\end{itemize}

\end{document}

请注意，您设置的方式是，schedule环境缩进的值\parindent。在我的 MWE 中，可以通过将的值设置\leftskip为 0pt 而不是 来删除它\parindent。
