Emacs:防弹列表? [英] Emacs: bulletproof up-list?
问题描述
我正在获得 up-list:扫描错误:不平衡括号
从此位置:
(foo "bar|")
up-list
doc:
此命令假设点不在字符串或注释中。 / p>
This command assumes point is not in a string or comment.
所以这是预期的行为。
但我不在乎。我只想从列表中向上移动。
有人可以建议一个上面列表
克隆,这样做正确吗?
So this is the expected behavior.
But I don't care. I just want to go upwards from a list.
Could someone suggest an up-list
clone that does the proper thing?
我在看比这个天真的代码更好:
I'm looking for something better than this naive code:
(defun up-list-naive ()
(interactive)
(while (not (ignore-errors (up-list) t))
(forward-char)))
推荐答案
编辑:并入Andreas Rohler的建议:
incorporated Andreas Rohler's suggestion:
这在您的测试用例中适用于我: / p>
This works for me in your test case:
(defun my-up-list ()
(interactive)
(let ((s (syntax-ppss)))
(when (nth 3 s)
(goto-char (nth 8 s))))
(ignore-errors (up-list)))
syntax-ppss
返回一个列表,如果你在一个字符串中,第三个元素存在,第八个元素是字符串的开头(如果你在一个,否则为零)。
syntax-ppss
returns a list, the third element of which exists if you're inside a string, and the 8th element is the beginning of the string (if you're in one, otherwise nil).
