关联计数器——同时步进（多个）计数器

Question

这（也许）不是一个真正的问题，而且可能已经有对我的建议/请求的答案了。

情况

有些包提供了最后一页的编号（即lastpage或“较新”的pageslts包），第一个包不能保证它确实包含总页数，特别是在命令之后\pagenumbering{}，第二个包提供了此功能（根据文档）

totcount对于计数器总值来说是一个非常有用的包，但是\chapters当\appendix使用或类似命令时，无法重置或对计数器进行其他操作，尤其是对于页面等。

我认为，如果还有另一个与page（或chapter等）相关的计数器，比如totalpages（或totalchapters），当 发出 时也会自动增加\stepcounter{page}，这样即使重置page计数器也不会对 产生任何影响，那就太好了totalpages。相关计数器最好\newtotcounters来自totcount包，但这不是强制性的。

可能存在编码情况，其中驱动计数器和相关计数器具有不同的值，但仍同时进行。

有一些相关问题，

• 关于\refstepcounter重置，例如 柜台和他们的“伙伴”
• 关于共享柜台（虽然我不确定这是否是我所说的同一个功能） 每页共享计数器

我对此提出了一个主张，使用来自的列表etoolbox和重新定义的\stepcounter命令，该命令贯穿整个列表并执行相关的计数器。

MWE 多次重置页码，以及部分计数\chapters等。该命令提供了与驱动程序计数器“绑定”的计数器列表。屏幕截图显示，即使重置驱动程序计数器也不会影响相关计数器的总值。在示例中，按设置有 30 页和 3 个部分，这些数字由应用于相关计数器的命令\DeclareAssociateCounters报告。\totvalue

当然，对驱动程序或相关计数器值的操纵\setcounter当然\addtocounter会导致偏差值。

是否有其他方法或包可以（更好地）处理计数器的同时步进？

我不认为aliascntH. Oberdiek 提出的那个包解决了同样的问题。

Answer 2

更新 2017/03/05该assoccnt软件包已被取代，xassoccnt并可作为1.3CTAN 上的版本使用——该软件包比 更强大assoccnt——请不要assoccnt再使用并切换到xassoccnt。

正如 egreg 所说：LaTeX 内核不提供这样的功能，也许有其他软件包具有此功能，所以我决定提供一个小包，上传到 CTAN 并可能很快就会推出。

驱动程序的输出与问题的快照基本相同。

笔记

• 目前还没有测试这几个命令的参数是否完全是计数器（名称）
• 没有测试可以证明两个（或更多）关联计数器不是相互关联的计数器。

我会不断提供更新和改进。
