回忆录，如何让 \makechapterstyle 知道章节标题是否在前面？

Question

对于我的书，我定义了自己的章节样式，我喜欢只在文档正文中（之后\mainmatter）使用它。在前言中，我喜欢保留默认的回忆录章节样式。

背景：

我的章节样式产生以下结果：

在前言中，我增加了文本宽度至章节标题的右边框（参见下面的 mwe）。因此，章节标题被推出页面（在本例中是目录标题，即：“内容”）。

为了使其可见，我正在寻找如何使我的章节样式清晰可见以及在哪里使用。对于星星，我喜欢在前面使用memoir默认样式。

母语：

问题：

如何改变我的\makechapterstyle，它将意识到\frontmatter并使用或默认的回忆录风格或新定义的风格（与中使用的风格非常不同\mainmatter）？

Answer 1

\if@mainmatter...\else ...\fi里面有帮助吗\makechapterstyle？

\frontmatter套\@mainmatterfalse。
