emacs 打开文本内容描述的一个文件

Emacs-general
1

emacs 选中某处文本内容，内容为一个路径，直接打开该路径，有什么实现方法

比如a.v内容为 aaaaaaaaaaaaaaaaa ~/cwh/work/b.v aaaaaaaaaaaaaaaaa

emacs 如何选中~/cwh/work/b.v直接打开b.v文件

2

M-x find-file-at-point 将其绑定到一个你觉得顺手的键上

3

话说有没有办法真的做到“选中后不用任何操作就打开”？

4

不用任何操作就打开，不乱了吗 不想打开也自动打开？？ image

这样讲光标放在文件路径位置，C-x C-a 效果如下图

回车即可

5

他意思应该是想把那个回车省掉

6

说实话我本来就目的不纯……

7

我觉得还算方便 哈

8

有个 thing-at-point 可以判断当前内容，可以试别filename, url等，根据不同的类型执行不同的操作应该早就有了把。

9

不如给我勾一个解决方案吧

我用的 xah-fly-keys，里面这个函数应该可以满足你需求。绝对路径，相对路径，http这些都可以打开。也不用敲额外的回车。要不试下？

很多时候文件名和其它文本 都是空格分开或是使用 “” 括起来的。这种情况下，不用选中直接就可以打开。

(defun xah-open-file-at-cursor ()
  "Open the file path under cursor.
If there is text selection, uses the text selection for path.
If the path starts with “http://”, open the URL in browser.
Input path can be {relative, full path, URL}.
Path may have a trailing “:‹n›” that indicates line number. If so, jump to that line number.
If path does not have a file extension, automatically try with “.el” for elisp files.
This command is similar to `find-file-at-point' but without prompting for confirmation.
