Adds filename completion for [file: entries

[hewner]

Comments/changes welcome! I am by no means an expert on autocomplete.

[hewner]

Anybody there?

Hi, @hewner
Thanks for your p-r. But, I'm busy now...
Please give me a time...

[hewner]

No problem - just keep me up to date.

Just a quick reminder this is still here

I'm very sorry my checking is delayed... <(_ _)><(_ _)><(_ _)>
I'll do it in a few days.

I think the following is better.

(defvar ac-source-org-ac-file
  '((init . (setq ac-filename-cache nil))
    (candidates . org-ac/file-candidate)
    (prefix . "\\[file:\\(.*\\)")
    (symbol . "f")
    (requires . 0)
    (action . ac-start)
    (limit . nil)))

• Probably init key is wrong. see (ac-define-source filename ... in auto-complete.el
• prefix key uses a first group in reguler-expression for ac-prefix
• We can start completion even if ac-prefix don't exist giving 0 to requires key

In addition, Could you change the definition of ac-source-org-ac-link-head?

(defvar ac-source-org-ac-link-head
  `((candidates . org-ac--get-link-head-candidates)
    (prefix . ,org-ac--regexp-link-head)
    (symbol . "l")
    (requires . 0)
    (cache)
    (action . (lambda ()
                (ac-pcmp/do-ac-action)
                (ac-start)))))

By this change, we'll be able to start completion automatically at the finish of the completion to start a link.

Thank you for giving such useful function.

BTW, in present, I don't use this extension to input a link but use org-linkany.el to do that.
I'd be glad if you check it.
