我正在尝试生成一本书中使用的人名索引。
首次出现时，会使用人物的全名（即名字和姓氏以及可能的附加说明）来介绍该人物，之后在文中只会使用该人的姓名。
我打算使用老旧的 makeindex 来生成索引，因为不需要其他索引。因此我编写了宏，一个用于人的初次出现，一个用于以后的所有出现。初次出现宏使用姓名和姓氏作为强制参数，第二个宏仅使用姓名作为强制参数。
\index我认为，通过-command 使用@类似这样的方式写入姓名会很聪明\index{#2@#2}（假设，人员姓名始终存储在 #2 中，其姓氏存储在 #3 中）。因此，对于初始外观，索引将如下所示：
\index{#2@#2, #3}
这是进一步露面的呼吁：
\index{#2}
不幸的是，Makeindex 不会将它们识别为唯一名称。即使我将第二个宏更改为使用 also @：
\index{#2@#2}
将显示为同名的第二个条目。
哪里出了问题？我必须改变什么？
以下是 MWE：

这是令人遗憾的结果，因为尽管这是一个人并且应该列为斯诺，查尔斯·珀西，1，2，但它却包含了斯诺先生的两个条目：
答案1
我的解决方案将名称和潜在描述存储到expl3属性列表中，并处理索引格式。如果没有描述，则提取普通格式，否则在\index- 调用中添加描述。
这样，就Index被“压缩”了。
我还曾经\NewDocumentCommand在 的末尾提供一个可选参数\InitPerson。
宏\displayname、\descriptionformat和\nodescriptionformat只是为了防止吞噬\ExplSyntaxOn...\ExplSyntaxOff制度中的空白的包装器。

答案2
之前的部分@仅用于排序，但\index{a@aa}和\index{a@aabb}是不同的項目。
Christian Hupfer 提出的代码可以简化。您也许应该重新考虑将第一个可选参数提供给时会发生什么\initpers。
