组织议程正则表达式搜索类别

我喜欢使用以下方式构建我的组织模式项目:CATEGORY:财产，但类别似乎不被认可org-agenda-filter-by-regexp（势必=）。当查看相当大的 TODO 项目列表时，能够将列表缩小到匹配的类别会很有帮助。

我知道我可以使用org-agenda-filter-by-category (<），但该命令必须在类别条目上执行。

有没有办法用正则表达式过滤组织议程包括类别？

下面的函数执行我想要的功能，但是我无法让它工作org-agenda调度程序作为自定义议程命令。

(defun rnkn/org-category-match (str)
  "Org Agenda match TODO headlines matching :CATEGORY: property STR."
  (interactive "sCategory: ")
  (org-tags-view t (concat "CATEGORY={" str "}")))

Type M-x org-agenda RET m然后输入正则表达式——例如，PropertyDrawerName={regex}

上一个答案（在原始发布者编辑问题之前）--当前版本org-element-property / org-element-headline-parser使用全部大写字母作为属性抽屉参数：
