lyx 中的 \swapnumbers

Question

我在 Mac 上使用 LyX 2.2dev 以及定理 (AMS)、定理 (AMS-Extended)、按节编号方程和定理 (按节编号) 模块。我在 LaTeX 序言中放入了 \swapnumbers，但数字仍然没有交换。

另外，定义一个新的定理或定义似乎需要缩进一个新段落，而我希望定理的编号从最左边开始。

编辑 下面是一张可以说明我的意思的图片：

以下是我所指的“MWE”：原始 LyX 文件：

感谢您的友好 MWE 和清晰的问题！

这里的问题是，您需要在 LaTeX 前言的顶部附近放置一些内容。LyX 中的前言只是整个 LaTeX 前言的一部分。您加载的 LyX 模块所贡献的前言部分恰好位于用户前言之上。正如 @barbara beeton 在评论中所述，您需要将命令\swapnumbers放在\newtheorem命令之前。在 LyX 中，有几种不同的方法可以解决这个问题。一种方法如下。我们定义一个“本地布局”（阅读帮助 > 自定义以了解更多信息），它恰好在其他模块之前输出。

为此，请转到“文档”>“设置”>“本地布局”并输入以下内容：

Preamble
\swapnumbers
EndPreamble

然后按“验证”。然后按“确定”。就这样。

这会导致以下 .lyx 文件（我的 LyX 开发比你的稍微新一些，因此可以更新并重新编译，或者只需将 480 替换为 479 就可以了）：
