Determine if a directory is .gitignored with vc

Question

I would like to determine if the current directory/file is ignored by .gitignore with vc. In this case, only git matters, but of course a general solution would be appreciated.

Answer 1

I'm afraid there is no such API in vc-mode or magit, but with little elisp you can implement all by yourself:

(defun my/is-git-ignored (file)
  (interactive "fFile:")
  (not (string-empty-p
        (shell-command-to-string (concat "git check-ignore " (shell-quote-argument file))))))
