Latex 日历获取单元格的日期

Question

我使用“日历”包为所教课程创建了教学大纲。表格中的一些条目突出显示了家庭作业和测验。

是否可以从日历中获取家庭作业和测验的日期，并将其用于另一个包含所有重要日期（家庭作业、测验、期中考试、期末考试等日期）的表格中？如果日历中测验和家庭作业的位置发生变化，重要日期表中的日期应自动更改。

我认为我们需要给测验和作业贴上标签，以便我们可以交叉引用它们。

这是代码。

Answer 1

这可以使用etoolbox包中的列表处理宏来完成。这个想法是定义一个新命令，显示日历中的重要事件，但也将信息（名称、章节、日期）存储在列表中。然后，在日历完成后，您可以循环列表longtable以显示项目。

etoolbox调用来自的列表处理宏，list[type]add其中类型表示在列表中存储信息的方式。在下面的代码中\listxadd使用，这意味着扩展和全局。需要扩展是因为日期值必须存储为原始数字，而不是随着日历天数不断变化而变化的宏，而全局是因为表中日历之外需要这些值。这些值作为表行存储在列表中，即name & chapter & date。

更新：您可以通过在日历中的相应位置插入额外命令来手动向表中添加行\listadd。在这种情况下，使用\listgadd（添加全局没有扩展）因为这允许在添加的内容类型方面具有更大的灵活性。例如，\multicolumn不允许使用命令，\listxadd因为多列的立即扩展会干扰列表处理。请注意，必须添加额外的行里面 \caltextnext或\caltexton，因为否则行会在最后添加。

\listxadd可以通过修改内的参数来调整表格行的格式\importantitem，例如添加用于备注的额外参数或包括年份。

处理过程包括定义循环函数\do，该函数需要在表格外部完成，并使用对列表的所有元素调用此函数\dolistloop。该\do函数包含\\\hline，即它完成表格行。

另一个问题是将日期打印为序数，例如第11届或者第三。该termcal包有一个宏（\ordinaldate），但该宏会导致 的列表处理内部出现错误etoolbox。因此，复制了包的一小部分nth来生成序数后缀。

Answer 2

使用 LaTeX 2ε 内核的\@starttoc/\addtocontents机制，您可以定义一个命令

\ImportantDate{⟨WorkAssignment⟩}{⟨chapter-number⟩}{⟨customary text⟩}

⟨工作任务⟩= 家庭作业 1 或测验 3
⟨章节编号⟩= 章节数
⟨习惯文字⟩= 习惯文本

哪个

• 交付： %⟨WorkAssignment⟩~(Chapter~⟨chapter-number⟩)
• via为文件\addtocontents创建一个条目 (loids =\@writefile\jobname.loids升是oF我重要d吃s) 表示调用带有参数的宏，该参数\LineWithImportantDate包含创建 longtable 的另一行所需的所有信息。

\listofImportantDates然后您可以拥有一个类似于\tableofcontents—via的宏，它\@starttoc导入 .loids 文件并 \write为 .loids 文件创建 -handle。

您可以使用\AtBeginDocument（来自 LaTeX 2ε 内核）和\AfterLastShipout（来自包尽头) 用于将 longtable-preamble/postamble 添加/添加到 .loids 文件前面或后面。

您需要重新定义\calprintdate以便\hypertarget创建一个。

您可以使用包的宏datetime2

• 用于计算星期几
• 获取星期几的名称
• 获取月份名称
• 以序数形式获取月份中的日期（附加^st、^nd、^rd、^th）。

您可以定义命令\Homework和\Quiz步骤计数器“家庭作业”相应的“测验”，然后调用，将剩余参数的收集留给。\ImportantDate{⟨WorkAssignment⟩}\ImportantDate

语法与自动生成的\ImportantDate相同：⟨WorkAssignment⟩

\Homework{⟨chapter-number⟩}{⟨customary text⟩}

\Quiz{⟨chapter-number⟩}{⟨customary text⟩}

这些命令的星号变体不会从重要日期列表生成到日历的超链接。

编辑1：与稍旧的 LaTeX 2ε 内核一样，\@writefile-mechanism 没有考虑到这一点，我从代码中\protected@file@percent删除了所有实例。\protected@file@percent

代码（保存为测试.tex) 在 Debian Buster x86 下使用 TeXLive 2020 成功编译。我必须编译四次而不删除中间的辅助文件，直到来自 latex 运行期间创建/更改的辅助文件的所有内容（longtable、hypertargets）都正确匹配。

编辑2：我添加了一个命令

\ImportantDateNote{⟨amount of empty cells at the left of the cell with the note (range from 0 to 2)⟩}%
                  {⟨amount of cells the note shall span (range from 1 to 3)⟩}%
                  {⟨flag <=0 or >0 denoting if vertical bar shall be drawn between two consecutive empty cells⟩}%
                  {⟨alignmant of note l r c p{0.15\textwidth}⟩}%
                  {⟨text of note⟩}

用于将所有注释放入重要日期的表中。

该表有三列，因此总和 ⟨带有注释的单元格左侧的空单元格数量（范围从 0 到 2）⟩ 和 ⟨注释应跨越的单元格数量（范围从 1 到 3）⟩不得超过值 3。
