删除 postheadhook thmtools 后的空白

Question

我想去掉后面愚蠢的空白postheadhook \newline （参见之前嗎）

在以下示例中：

    %!TEX TS-program = XeLaTeX
%!TEX encoding = UTF-8 Unicode

\setlength{\parindent}{0mm}
\lipsum[1]
\begin{example}[asd][asd]

\end{example}
\lipsum[1]
\end{document}  

我怎样才能实现这个目标？

Answer 1

这是由于插入 造成的\label。我在插入后添加了\ignorespaces，这似乎消除了虚假的间距：

  headings=normal,
  titlepage=true

\usepackage[centertags]{amsmath}

\usepackage{amsthm}
\usepackage{thmtools}

\usepackage{lipsum}


\newlength{\spacingtheorem}
\setlength{\spacingtheorem}{2mm}
\declaretheoremstyle[%
  headfont=\bfseries,%
  notebraces={(}{)},%
  bodyfont=\normalfont,%
  notefont=\itshape,%
  headpunct={:},%
  postheadspace=0mm,%
  postheadhook={\hspace{0mm}\newline},%{\textcolor{red}{\rule[.6ex]{\linewidth}{0.4pt}}\\},%
  spacebelow=0mm,%
  spaceabove=0mm,%
  mdframed={%
    frametitlealignment=\raggedright,%
    linecolor=black,%
    middlelinewidth=1pt,%
    innertopmargin=0.5\baselineskip,%
    innerbottommargin=0.5\baselineskip,%
    innerleftmargin=10pt,%
    innerrightmargin=10pt,%
    skipbelow=\dimexpr-\parskip+\spacingtheorem\relax,%
    skipabove=\spacingtheorem,%
    font=\upshape%
  }%
]{myFramedTheoremStyle}%

\declaretheorem[

   \IfNoValueTF{#2} {}{\label{#2}\ignorespaces}%
  }%
  {%
   \end{example1}%
  }%

Answer 2

我不确定你为什么要在框架前后留出如此狭窄的空间。postfoothook不过，钥匙可以提供帮助。后面的垂直空间mdframed通常很奇怪。

当然，example为了避免\label发出虚假空格而使用两个可选参数进行定义是错误的。

也许从的文档中看不清楚thmtools，但postheadspace可以接收值，因为它实际上是一个接受它\newline的间距参数的接口（参见其定理风格的定义）。amsthmbreak

环境名称周围的括号应该是直立的，所以我在定义中使用了\textup(和。\textup)
