xcoffins - 用...固定棺材-在 ExplSyntax 中

我继续使用 xcoffins 进行我的网格设置项目，并将代码转换为 latex3。

从较早前问题我了解到，当我第一次将两个棺材连接在一起时，杆子保持为<pole name>，后来保持为<coffin name>-<pole name>。

将身体棺材连接到页面棺材（第一次连接）可以很好地工作

\coffin_attach:NnnNnnnn \l__jgrid_page_coffin { T } { l } \l__jgrid_body_coffin { T } { l } { \dim_use:N \l__jgrid_body_offsetx_dim } { \dim_use:N \l__jgrid_body_offsety_dim }

但我在连接下一个棺材时卡住了。\coffin_show_structure:N \l__jgrid_page_coffin有输出

>  \l__jgrid_page_coffin -T  =>  {0.0pt}{845.04684pt}{1000pt}{0pt}
>  \l__jgrid_body_coffin -l  =>  {54.06023pt}{116.29182pt}{0pt}{1000pt}

但以下代码不起作用：

\coffin_attach:NnnNnnnn \l__jgrid_page_coffin { \l__jgrid_page_coffin -T } { \l__jgrid_page_coffin -l } \l__jgrid_head_coffin { T } { l } { \dim_use:N \l__jgrid_head_offsetx_dim } { \dim_use:N \l__jgrid_head_offsety_dim }

我该如何“构建” <l__jgrid_page_coffin>-<T>？如果这是一个微不足道的问题，请记住这是我在 latex3 中的第一步。非常感谢，Jens。

第二个答案：

经过更多的测试之后，我（希望）能够更好地理解，定位如何根据所使用的功能而有所不同。

\coffin_attach:NnnNnnnn \l__jgrid_page_coffin { T } { l } \l__jgrid_foot_coffin { t } { l } { \dim_use:N \l__jgrid_body_offsetx_dim } { \dim_use:N \l__jgrid_body_offsety_dim - \textheight-\baselineskip }

和

\coffin_join:NnnNnnnn \l__jgrid_page_coffin {  \l__jgrid_page_coffin-T } {  \l__jgrid_page_coffin-l } \l__jgrid_foot_coffin { T } { l } { \dim_use:N \l__jgrid_body_offsetx_dim } { \dim_use:N \l__jgrid_body_offsety_dim - \textheight-\baselineskip}

在定位方面产生相同的结果。虽然\coffin_join第一个棺材的边界框被更新以包含两个棺材的边界框，\coffin_attach但第一个棺材保持不变。

第一个答案： 感谢 Ulrikes 的评论，我可能通过将代码简化为 MWE 找到了答案。在我看来，以前收到的解释“起初将杆子保存为（杆子名称），后来保存为（棺材名称-杆子名称）”仅对 xcoffins-DocumentFunctions 有效？！

有人可以证实这一点吗，或者它只是在这个简单的 MWE 中工作？
