如何搜索保存为变量的完整组织标题 [英] How to search for a complete org headline that was saved as a variable
问题描述
函数(org-heading-components)
和(org-element-property)
为星号数也优先。我想将整个标题存储为变量,然后使用重新搜索转发
(或类似的功能)返回到那个标题,但是我预见到当找不到整数时会发生的问题。我需要将整个标题存储为一个变量,因为我经常有要重复的标题的条目,但其他组件是不同的。
例如,以下todo: / p>
**活动[#A]询问stackoverflow上的天才如何做到这一点。 :当用(org-heading-components)
code>看起来像这样:
(2 2活动65询问stackoverflow上的天才如何做到:lawlist:)
所以,当将它作为一个变量存储, c $ c> re-search-forward 会出现问题,因为 2 2
与 **
和 65
与 [#A]
不同。
(defun lawlist()
(interactive)
(let *(
(点))
(完整标题(组织标题组件)))
* * *
(goto-char(point-min))
(重新搜索 - 完成标题nil t)))
strong> EDIT (2013年12月15日):根据变量 org-heading-regexp
(在 org.el中定义)更新解决方案
)和其修改包括(如果存在)包含截止日期的第二行 - 即 lawlist-org-heading-regexp
。修订版还包括一个刚刚通过@Drew超级用户教给我的一个漂亮的函数 regexp-quote
:https://superuser.com/questions/688781/how-to-highlight- string-and-unhighlight-string-in-buffer-make-overlay?noredirect = 1#comment874515_688781 (buffer-substring-no-properties beg end)
是用于将字符串设置为变量。
编辑(2013年12月17日):添加 isearch-highlight
和 isearch-dehighlight
,并注释掉 highlight-regexp
和 unhighlight-正则表达式
。当使用更复杂的函数移动点时, highlight-regexp
不能可靠地突出显示整个字符串 - 这可能是因为屏幕没有刷新,或者也可能是由其他因素引起的 - 例如,hl-line-mode等) - 放置各种 sit-for 0
没有解决问题与 highlight-regexp
- isearch-highlight
更好地工作。
编辑(2014年1月6日):另请参阅这个相关的线程,获取完整的正则表达式,以匹配从星号到笔记末尾的整个todo的任何元素:
(defvar lawlist-org-heading-regexp
^ \\(\\ * + \\)\\(? + \\(。*?\\)\\)?[\t] * \\(\\\
。* DEADLINE。* $ \\)
匹配标题,加上seco )
(defun example()
(interactive)
(switch-to-buffer(get-buffer-createfoo))

编辑(2013年10月27日):作为进化过程的历史部分暂时保留的最终解决方案。但是,它不再是首选方法。
(defun lawlist-org-heading-components()
org-back-to-heading t)
(if(let(case-fold-search)(look-in org-complex-heading-regexp))
(concat
(cond
((等于(org-match-string-no-properties 1)**)
^ [*] [*])
((等于(org-match-string - 不属性1)*)
^ [*]))
(cond
((和(match-end 2))(aref(match-string 2)1 )
(concat(org-match-string-no-properties 2))))
(cond
((和(match-end 3))(aref(match-string 3)
(concat\\(org-match-string-no-properties 3))))
(cond
((和(match-end 4 )(aref(match-string 4)3))
(concat(org-match-string-no-properties 4))))
(cond
((和(match -end 5)(aref(match-string 5)4))
(concat(org-match-string-no-properties 5))))))))
The function (org-heading-components)
and (org-element-property)
produce integers for the number of stars and also for the priority. I'd like to store the entire headline as a variable and then use re-search-forward
(or a similar function) to go back to that heading, but I foresee the problem that will occur when it cannot find an integer. I need to store the whole heading as a variable, because I often have todo entries with duplicate titles but the other components are diferent.
For example, the following todo:
** Active [#A] Ask the geniuses on stackoverflow how to do this. :lawlist:
when evaluated with (org-heading-components)
looks like this:
(2 2 "Active" 65 "Ask the geniuses on stackoverflow how to do this." ":lawlist:")
So, when storing that as a variable and later using re-search-forward
there will be problems because 2 2
is not the same as **
, and 65
is not the same as [#A]
.
(defun lawlist ()
(interactive)
(let* (
(beg (point))
(complete-heading (org-heading-components) ))
* * *
(goto-char (point-min))
(re-search-forward complete-heading nil t) ))
EDIT (December 15, 2013): Updated solution based upon the variable org-heading-regexp
(defined within org.el
) and a modification thereof to include (if it exists) a second line containing a deadline - i.e., lawlist-org-heading-regexp
. The revision also includes a nifty function regexp-quote
that was just taught to me by @Drew over on superuser: https://superuser.com/questions/688781/how-to-highlight-string-and-unhighlight-string-in-buffer-make-overlay?noredirect=1#comment874515_688781 (buffer-substring-no-properties beg end)
is used to set the string as a variable.
EDIT (December 17, 2013): Added isearch-highlight
and isearch-dehighlight
, and commented out highlight-regexp
and unhighlight-regexp
. When moving the point around with more complex functions, highlight-regexp
does not reliably highlight the entire string -- this may be because the screen has not refreshed, or it may also be caused by other factors -- e.g., hl-line-mode, etc.) -- placing various sit-for 0
did not fix the issue with highlight-regexp
-- isearch-highlight
works better.
EDIT (January 6, 2014): See also this related thread for a complete regexp to match any element of the entire todo from stars through to the end of the notes: https://stackoverflow.com/a/20960301/2112489

EDIT (October 27, 2013): Prior solution that is being preserved temporarily as a historical part of the evolution process towards a final answer. However, it is no longer a preferred method.
