I use Notmuch to manage my emails (and that's just wonderfully fast) and use the Emacs frontend for it. But when I wanted to save attachements, it was not that easy to create folders. I had to exit the save, open a terminal, a dired or whatever create the folder… I use Helm for managing completion in emacs (and that's a nice piece of software too).
To avoid that and with the help of Sacha Chua, I managed to add a shortcut in helm read file:
(setq enable-recursive-minibuffers t) (minibuffer-depth-indicate-mode 1) (define-key helm-read-file-map (kbd "C-c c") 'my-helm-make-folder) (defun my-helm-make-folder (str) "Make folders from helm save" (interactive (list (read-from-minibuffer "Create folder: " (minibuffer-contents-no-properties) nil nil nil))) (make-directory str t) )
You have to enable the minibuffer recursive mode (and I added the recursive counter too) for it to work as it asks you for the creation of the folder.
By removing the /interactive/ arguments and function arguments, it will create the folder directly without asking and you will be able to avoid activating the /minibuffer recursive mode/ (I wonder why it's not activated by default you can mail me).
