Changing company-mode settings while still running emacs

Changing company-mode settings while still running emacs

[Heime via Users list for the GNU Emacs text editor]

I am using 

    (add-hook 'after-init-hook 'global-company-mode)

to enable company-mode globally.

I would like the ability to change company-backends and other company 
variable and apply them globally while still running emacs.  

How can one do this?

   M-x customize-variable

usually helps - like with most other options in Emacs (it has a "save" 
button).

Or you can manipulate those values using Lisp. I'm guessing you're not 
at that level (hence the question), so the Customize interface should be 
the easier option.

I want to do it with lisp.  Have made this interactive function to
set up the company-backends, but instead of applying the changes 
locally, I want to apply them globally.

(defun companiol-backends-kntlr (actm-seqr)

  (interactive
    (let* ( (cseq '("company-dabbrev"
                    "company-dabbrev-code"
                    "company-keywords"
                    "company-capf"
                    "company-yasnippet"
                    "company-files"))

            (backends-seltr
                (completing-read-multiple "Backends: " cseq nil t)))

      (list (mapcar #'intern backends-seltr))))

    (setq company-backends actm-seqr)

    ;; Refresh company-mode to apply the changes
    (when (bound-and-true-p company-mode)
      (company-mode -1) (company-mode 1)) )

No need to re-enable the mode to have the new value picked up. As long 
as there's no buffer-local value (set up by yourself or your 
"distribution" such as Doom or Spacemacs), that should work right away, 
at least if there is no current completion session (to simplify, no 
popup visible).
