Emacs 组织模式在标题属性后插入文本



我想在组织文件中的所有标题之后插入一些文本。

例如,假设我有:

* Header foo
:PROPERTIES:
:EXPORT_FILE_NAME: ./tmp/Test
:END:
* Header bar

运行后(在标题"新文本"后插入(,我应该有:

* Header foo
:PROPERTIES:
:EXPORT_FILE_NAME: ./tmp/Test
:END:
NEW TEXT
* Header bar
NEW TEXT

到目前为止,我管理的最好的事情是执行以下操作:

(goto-char (point-min))
(goto-char (re-search-forward "^*"))
(set-mark (line-beginning-position))
(goto-char (point-max))
(org-map-entries
(lambda () (progn (forward-line)(new-line)(previous-line) (insert "NEW TEXT") )

但是,这会在属性之前插入文本。


编辑:

(defun goto-header()
(interactive)
(org-back-to-heading)
(let ((beg-end (org-get-property-block))):
(when beg-end
(let ((end (cdr beg-end)))
(goto-char end))))
(forward-line)
(newline)
(previous-line))

用作将点移动到正确位置的一种方式,以便插入可以正确插入文本。有没有更好的方法?

这是一个注释过多的函数,可以做你想要的。

(defun my/insert-text-after-heading (text)
"Insert TEXT after every heading in the file, skipping property drawers."
(interactive "sText to insert: ")
;; The Org Element API provides functions that allow you to map over all
;; elements of a particular type and perform modifications. However, as
;; as soon as the buffer is modified the parsed data becomes out of date.
;;
;; Instead, we treat the buffer as text and use other org-element-*
;; functions to parse out important data.
;; Use save-excursion so the user's point is not disturbed when this code
;; moves it around.
(save-excursion
;; Go to the beginning of the buffer.
(goto-char (point-min))
;; Use save-match-data as the following code uses re-search-forward,
;; will disturb any regexp match data the user already has.
(save-match-data
;; Search through the buffer looking for headings. The variable
;; org-heading-regexp is defined by org-mode to match anything
;; that looks like a valid Org heading.
(while (re-search-forward org-heading-regexp nil t)
;; org-element-at-point returns a list of information about
;; the element the point is on. This includes a :contents-begin
;; property which is the buffer location of the first character
;; of the contents after this headline.
;;
;; Jump to that point.
(goto-char (org-element-property :contents-begin (org-element-at-point)))
;; Point is now on the first character after the headline. Find out
;; what type of element is here using org-element-at-point.
(let ((first-element (org-element-at-point)))
;; The first item in the list returned by org-element-at-point
;; says what type of element this is.  See
;; https://orgmode.org/worg/dev/org-element-api.html for details of
;; the different types.
;;
;; If this is a property drawer we need to skip over it. It will
;; an :end property containing the buffer location of the first
;; character after the property drawer. Go there if necessary.
(when (eq 'property-drawer (car first-element))
(goto-char (org-element-property :end first-element))))
;; Point is now after the heading, and if there was a property
;; drawer then it's after that too. Insert the requested text.
(insert text "nn")))))

要转到属性抽屉的末尾,您可以使用(org-end-of-meta-data t).所以一个较短的函数是

(defun goto-header()
(interactive)
(org-back-to-heading)
(org-end-of-meta-data t)
(forward-line)
(newline)
(previous-line))
