下面我有三类定理:
- 一个“普通”定理,只有头部“定理”,如第三个定理;
- 一个定理既有标题又有注释,“定理(...)”,如第二条;
- a
namedtheorem
,其中注释成为名称,与第一个一样。
问题:需要进行哪些修改才能使输出\listoftheorems
中删除namedtheorem
,但在具有头部和注释的定理中保留注释的括号?
失败尝试 1:删除了括号,namedtheorem
但不幸的是,也删除了带有注释的条目中的括号。

失败尝试2:注释掉该行\renewcommand\thmtformatoptarg[1]{#1}
。然后括号仍然保留在条目周围namedtheorem
。
问题重述:theorem
因此,我怎样才能以某种方式结合具有括号注释的 和 的不同处理方式namedtheorem
呢?

答案1
除了您询问的问题之外,您发布的代码中还存在几个问题。
- 在您的最小示例中,执行的操作不执行任何操作
\patchcmd
(它所做的就是删除定理,title
使其不显示在listoftheorems
仅适用于未编号定理。这对我来说没有任何意义,所以我在下面的代码中将其删除。 - 该
\makeatletter...\makeatother
对应该包含使用该@
符号的所有内容,目前您的\declaretheoremstyle
宏不包括它,因此您显示的代码与其编码意图不同。我已将移至\makeatother
正确位置,并\thmt@space
从基本中删除了要删除的声明thmstyle
,因为该空间应该在那里,不应被删除。 - 在定义时
namedtheorem
,您指定了name
和title
;它们是同义词,您应该只指定一个。
现在,谈谈真正的问题:宏的使用与如何处理定理列表\thmtformatoptarg
紧密相关。具体来说,我们注意到:thmtools
<project>.loe
包含定理列表的所有定理条目的文件使用。\thmtformatoptarg
这意味着对 的任何更改\thmtformatoptarg
都将自动应用于所有条目,并且您无法有选择地进行更改。- 而且让人恼火的是,输入
onlynamed
的键会\listoftheorems
检测内容行中的存在\thmtformatoptarg
来决定是否显示该条目。
为了解决这两个问题,下面是一些小技巧:
- 我们重新定义了如何
namedtheorem
将 写入loe
文件,以完全忽略\thmtformatoptarg
。最简单的方法是完全重新定义事情的发展方式,而不是修补,所以我还删除了xpatch
。 - 我们假设的每个实例都
namedtheorem
带有一个可选参数(如果没有,定理名称将为空......),因此,onlynamed={namedtheorem}
我们不需要测试,而只需执行show={namedtheorem}
功能上应该相同的操作。
这样,就可以获得以下 MWE:

输出:
为了使该过程自动化,如果您有多个环境,我们可以重新定义\thmt@mklistcmd
以自动执行正确的操作。可能有更好的方法来实现这种逻辑,但以下方法应该可行。(基本上,\thmt@thmname
我们不是打印 ,而是测试它是否为空,如果为真,则打印可选参数。但这意味着当需要打印可选参数时,如果它已经代替了空的 ,我们应该完全抑制它的打印\thmt@thmname
。注意:我没有费心对无编号定理进行类似的更改;希望您可以通过将其与 中的定义进行比较来自己找出要更改的内容thmtools/thm-listof.sty
。)
