有没有一种方法可以在整个文档中为使用 Linguex 编写的示例定义单倍行距（我不使用其他软件包作为示例），而不必\singlespace在每个示例之前使用超过 100 次？换句话说，我需要我的文件看起来像这样：
当应用原始解决方案时，树木中的图形会变得疯狂，如下所示：
\documentclass{article}
\usepackage[left=3cm, right=3cm, top=3cm, bottom=3cm]{geometry}
\usepackage{graphicx}
\usepackage{rotating}
\usepackage{epstopdf}
\usepackage[nocenter]{qtree}
\usepackage{linguex}
\usepackage{tree-dvips}
\usepackage{tikz}
\usepackage{setspace}
\usepackage{linguex}
\linespread{1.0}
\begin{document}
I've removed lipsum in order to make the running text shorter so that both
examples fit on the same page. Also, I probably will have to try
\textsf{tikz-qtree-compat}, but I'm not sure if it's compatible with
\textsf{qtree} (most of my recent files already include \textsf{qtree}...).
\ex.\ag. Das ist kein Beispiel. \\
that is no example \\
\glt{ That is not an example.}
\bg. Das ist kein Beispiel. \\
that is no example \\
\glt{That is not an example.}
As a side note: I had to include the page dimentions specification in this
document. Otherwise the following example got printed on a page placed
horizontally (maybe it's due to the inclusion of the\textsf{ rotating}
package, which is needed for the positioning of the braces, maybe not, I
haven't seen this problem ever before). Nevermind.
\ex. spans looking fine\bigskip\\

\end{rotate}

\end{document}
输出如下所示：
然而，当
\usepackage{etoolbox}
\pretocmd{\ex}{\vspace{\Exredux}\begin{singlespace}}{}{}
\renewcommand{\ExEnd}{%
\ifnum\theExDepth=0\global\unembeddedfalse\end{singlespace}\vspace{.5\Exredux}\else%
\end{list}\addtocounter{ExDepth}{-1}\ExEnd\fi}
添加了，并且更改了正文的行距，例如
\linespread{1.75}
输出将括号改为 1.75，现在整个内容如下所示：
PS. 请注意，由于各种原因（例如内容适合某些页面等），我需要使用 \lineaspread 规范，而不是简单地使用 \doublespace。
答案1
这需要linguex直接修改示例代码。由于linguex实际上没有将示例定义为环境，因此它比它应该的更棘手。此外，为了获得示例上方和下方的间距，我添加了一些有点棘手的\vspace命令。如果您需要示例后有更多空间，请设置..5中的\vspace{.5\Exredux} 0（默认\Exredux设置为）。-\baslineskip
