regex - 组织议程正则表达式搜索类别

Question

我喜欢使用 :CATEGORY: 来构建我的 org-mode 项目。属性，但是 org-agenda-filter-by-regexp 似乎无法识别类别(绑定(bind)到 = )。在查看相当大的 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 ( < )，但此命令必须在类别条目上执行。

有没有办法正则表达式过滤包括类别的组织议程？

下面的函数执行我想要的，但是我无法从 org-agenda 开始工作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 "}")))

Answer 1

输入 M-x org-agenda RET m然后输入正则表达式——例如，PropertyDrawerName={regex}
上一个答案 (在原发帖人编辑问题之前)——org-element-property 的当前版本/org-element-headline-parser对属性抽屉参数使用所有大写字母:
