company-mode help

[Richard Riley]

Could someone help me with company-mode please. I cant find much
documentation on how to use it and am not sure if "(company-mode)" is
sufficient. I understand I can call "company-mode" at any time, but is
there no "global-company-mode" type thing or utility function to turn it
on for common programme language types? In addition, (I emailed Nikolaj
too), but do I have to do something special for it to complete structure
members in C/C++? it seems  a wonderful addition when interfaced with
cedet combined with its own built in completion filtering and context
help.

(dolist (hook (list
               'emacs-lisp-mode-hook
               'lisp-mode-hook
               'lisp-interaction-mode-hook
               'scheme-mode-hook
               'c-mode-hook

               'sh-mode-hook
               ))
  (add-hook hook 'company-mode))

How about this? :)

Yes, that would be the brute force way, but I thought it would be
included in the package some how if there are already semantic backends
etc.

How's your new IDE coming along?

I've added a global-company-mode in 0.4.1.

The reason for this is that the structure member (after the -> or .) is
considered a new symbol by Emacs, making it shorter than `company-minimum-prefix-length'.


For 0.4.1, a workaround could be an electric command:

(defun company-electric-dot ()
  "Insert a dot and start completion, unless in a string or comment."
  (interactive)
  (insert-char ?. 1)
  (unless (company-in-string-or-comment)
    (company-auto-begin)))

(defun company-electric-greater-than ()
  "Insert a dot and start completion, unless in a string or comment."
  (interactive)
  (insert-char ?> 1)
  (and (eq (char-before (1- (point))) ?-)
       (not (company-in-string-or-comment))
       (company-auto-begin)))

(define-key c-mode-base-map "." 'company-electric-dot)
(define-key c-mode-base-map ">" 'company-electric-greater-than)
(define-key c++-mode-map ">" 'company-electric-greater-than)


I'll figure out a more universal solution.

Please don't put this last into C or (especially) C++ mode.  > is bound

screw-ups, particularly as < would still be bound to `c-electric-lt-gt'.
OK, I know it's only meant as a temporary thing.  But couldn't you do it
as a defadvice around `c-electric-lt-gt'?
