我正在寻找一种与我所说的“注释”相匹配的方法，“注释”是组织任务的最后一行(或一组行)，上面写着:“这些是任务的注释。 “
我已经编写了一个非常长的正则表达式，可能可以完成这项工作，但我希望组织模式已经提供了更好的东西:
"^\\(\\*\\*\\)\\(?: +\\(Active\\|Next Action\\|Hold\\|Reference\\|Delegated\\|Postponed\\|Waiting\\|Someday\\|Planning\\|Canceled\\|None\\)\\)?\\(?: +\\(\\[#.\\]\\)\\)?\\(?: +\\(.*?\\)\\)??\\(?:[ ]+\\(:[[:alnum:]_@#%:]+:\\)\\)?[ ]*\\(?:\\(\n\\)\\)?\\(?: +\\(DEADLINE:\\|SCHEDULED:\\)\\)?\\(?: +\\(<\\)\\([^>]+\\)\\(>\\)\\)?\\(?: +\\(DEADLINE:\\|SCHEDULED:\\)\\)?\\(?: +\\(<\\)\\([^>]+\\)\\(>\\)\\)?\\(?:\\(\n\\)\\)?\\(?: +\\(CLOSED:.*\\)\\)?\\(?:\\(\n\\)\\)?\\(?: +\\(:PROPERTIES:\\)\\)?\\(?:\\(\n\\)\\)?\\(?: +\\(:ToodledoID:\\)\\)?\\(?: +\\([0-9]+\\)\\)?\\(?:\\(\n\\)\\)?\\(?: +\\(:ToodledoFolder:\\)\\)?\\(?: +\\(EVENTS\\|TASKS\\|UNDATED\\|DONE\\|CONTACT\\)\\)?\\(?:\\(\n\\)\\)\\(?: +\\(:Hash:\\)\\)?\\(?: +\\(.*+\\)\\)?\\(?:\\(\n\\)\\)?\\(?: +\\(:END:\\)\\)?\\(?:\\(\n\\)\\)?\\(.*\\(?:\n.*\\)*?\\)\\(?:^\\)"

我发现的解析组织任务的最完整示例使用org-element-parse-buffer，但我仍然没有看到仅提取注释的关键:https://github.com/yyr/org-mode/blob/master/testing/lisp/test-org-element.el
如果可能的话，我想要类似于此想象代码(org-element-property :notes (org-element-at-point))，其中不需要缩小子树范围来提取注释。我有几百个任务，我正在寻找一种方法来快速梳理主组织文件并创建我自己的自定义议程缓冲区，以显示第一个和也许第二行(如果截止日期或已安排)和末尾的注释如果存在。我有一种感觉，如果我必须缩小到 200 个任务的子树，那么生成最终显示将会有很大的延迟。
任务的前两行已经这样处理:
(defvar lawlist-org-heading-regexp
"^\\(\\*+\\)\\(?: +\\(.*?\\)\\)?[ \t]*\\(\n.*DEADLINE.*$\\)"
"Custom match org headline, plus the second line with a deadline.")
(setq txt
(save-excursion
(org-back-to-heading t)
(when (looking-at org-heading-regexp)
(concat
(match-string 1)
" "
(match-string 2)
(if (and (looking-at lawlist-org-heading-regexp) (match-string 3))
(match-string 3))
"\n" )))) )
(message "%s"(org-element-map (org-element-parse-buffer) 'paragraph 'identity nil t)) 给我以下内容:

最佳答案
编辑(2014 年 1 月 7 日):第一份工作草案。正则表达式的尾部将匹配注释，直到下一个空行 - 即，注释可能是多行，带有硬回车，并且它们之间没有空行。
编辑(2014 年 1 月 14 日):修订了 31 和 32，以便缓冲区末尾不需要最终的新行 - 即，任务末尾没有注释缓冲区现已被识别。将 20 修改为 24，以便 :ToodledoID: 抽屉和 :ToodledoFolder: 抽屉的位置可以互换。修改了示例 get-whopper 函数以排除 32。
编辑(2014 年 11 月 14 日):稍微更新了正则表达式，但功能保持不变。
编辑(2014 年 12 月 2 日):删除了自定义功能并替换为库存 org-back-to-heading。
编辑(2014 年 12 月 6 日:对正则表达式进行重大修改。正则表达式现在支持大多数条目的可选项目，并且缓冲区末尾不需要最终新行。随着在新版本中，正则表达式可以在自定义 *Org Agenda* 缓冲区中使用，该缓冲区仅显示原始待办事项中的部分项目 - 例如，标题 + 截止日期/计划/关闭 + 注释；或标题 +仅注释。但是，:tag: 是强制 anchor — 即，正则表达式至少需要一 (1) 个标记才能正常工作。行结尾 — 即 \n -- 不再编号匹配条目。正则表达式现在支持捆绑在一起的待办事项条目，没有任何新行将它们分隔开。请参阅有关非捕获组的相关线程: https://stackoverflow.com/a/3513858/2112489 另请参阅有关多行正则表达式 emacs: http://www.emacswiki.org/emacs/MultilineRegexp
