使用 thmtools 继续具有枚举项的定理类环境

Question

要继续一个定理，您可以使用continuesthmtools 的键。它将前一个定理的标签作为值。可以通过重新定义命令来自定义显示的文本\thmcontinues，但为了在 MWE 中获取格式，我定义了一个mycontinues稍微滥用该headpunct键的新键。这解决了问题 1 和 2。请注意，问题 1 是由于您在定理开头后添加了文本。这与您编写的相同

\begin{theorem} some text
\begin{enumerate}

对于问题 3，请注意 enumitem 文档中提到密钥时说resume，

这是在本地完成的。如果您想要全局恢复，请参阅下一节系列。

因此，为了退出定理环境创建的组，您必须手动设置series=<name>then 调用resume*=<name>。

这是包含这些更改的示例。

要获得格式“1.1 示例，继续（一些示例）”，您可以使用键headformat。由于这与交互不佳\swapnumbers，我定义了一个命令\unswapnumbers，您可以在声明定理之前调用该命令来取消交换效果。
