How to set a directory local variable for a directory itself non-recursively? I don't want the variable set in .dir-locals.el affect the sub-directories.


Edited:

My use case is: I'd like to hide dot files under ~ by setting dired-omit-files since there are quite a lot of them in my home directory. But I do not want to hide dot files of any other subdirectory of ~. Though I think I can set it using some dired-mode-hook by comparing buffer-name or buffer-file-name, I guessed there may be simpler solution by using directory local variables.

  • You could test (string= (expand-file-name dired-directory) (expand-file-name "~/")) to see whether the current dired buffer is visiting your home directory. – phils Dec 7 '20 at 3:00

No, there isn't. You can set the variable in the directory-local variables, and the unset it in the child directory's variables. Or you can use file-local variables.

  • There so many subdirectories though... – stackunderflow Dec 6 '20 at 9:17

    @stackunderflow I suggest you edit the question to explain your use-case in detail. What you're asking for isn't supported, but depending on what you're actually trying to achieve, there might be other convenient options. – phils Dec 6 '20 at 9:26
  • Then consider using file-local variables instead. Or you could certainly consider extending Emacs so that it could support non-recursive directory-local variables. – db48x Dec 6 '20 at 9:26
  • @phils I've updated the question details. – stackunderflow Dec 7 '20 at 0:26
