helm-M-x with initial inpu

[Louis Pan]

Hi, I'm wondering if it is possible to bind a key to 'helm-M-x with some initial input.

Use case: eg.

(global-set-key (kbd "M-p") (apply-partially #'helm-M-x-with "helm-projectile"))

I'd like to bind a key to "helm-projectile" so the one key brings up helm with an already narrowed down list of candidates.

Currently, I am using "M-x" then typing "helm proj" manually, but I'm hoping that I'll be able to skip a step.

I apologise if this is possible and  documented somewhere, but my google fu has failed me.

I don't know of a built-in solution. I would try with
`minibuffer-with-setup-hook', like in

#+begin_src emacs-lisp
(minibuffer-with-setup-hook
(lambda () (insert "helm-"))
(helm-M-x-read-extended-command))
#+end_src


Regards,

Michael.

I spoke too soon, but I only had to modify your code a little bit. Your idea was essential to getting it working. The following works:

(defun helm-M-x-with (str)

  (minibuffer-with-setup-hook

       (lambda () (insert str))

    (call-interactively 'helm-M-x)))

(global-set-key (kbd "M-p") #'(lambda () (interactive) (helm-M-x-with "helm-projectile ")))

Yeah, I thought you would figure out the rest, it was already late ;-)
