Try to understand the ora-company-number function again.

Try to understand the ora-company-number function again.

[Hongyi Zhao]

I try to understand the  ora-company-number function [1] again:

(defun ora-company-number ()
"Forward to `company-complete-number'.

Unless the number is potentially part of the candidate.
In that case, insert the number."
(interactive)
(let* ((k (this-command-keys))
(re (concat "^" company-prefix k)))
(if (or (cl-find-if (lambda (s) (string-match re s))
company-candidates)
(> (string-to-number k)
(length company-candidates))
(looking-back "[0-9]+\\.[0-9]*" (line-beginning-position)))
(self-insert-command 1)
(company-complete-number
(if (equal k "0")
10
(string-to-number k))))))

I've figured out all the intention of the above code snippet except
the following line:

(looking-back "[0-9]+\\.[0-9]*" (line-beginning-position)

I can't understand why the regexp used here must be written in this
form. Any hints will be appreciated.

And I also find another version of this function [2] defined as follows:

(defun ora-company-number ()
"Forward to `company-complete-number'.

Unless the number is potentially part of the candidate.
In that case, insert the number."
(interactive)
(let* ((k (this-command-keys))
(re (concat "^" company-prefix k)))
(if (cl-find-if (lambda (s) (string-match re s))
company-candidates)
(self-insert-command 1)
(company-complete-number (string-to-number k)))))

Based on my tries, the following code snippet is enough:

  (defun ora-company-number ()
    "Forward to `company-complete-number'.
     Unless the number is potentially part of the candidate.
     In that case, insert the number."
    (interactive)
    (let* ((k (this-command-keys))
           (re (concat "^" company-prefix k)))
      (if (cl-find-if (lambda (s) (string-match re s))
                      company-candidates)

      (self-insert-command 1)
        (company-complete-number
         (if (equal k "0") 10
           (string-to-number k)))
    )))

I came up with the following solution that seems to work:

```emacs-lisp
(use-package comany
  :config
  (setq company-tooltip-limit 16
      company-quick-access-keys '("1" "2" "3" "4" "5" "6" "7" "8" "9"
"0" "q" "w" "e" "r" "t" "y"))

  (defun hz-company-number ()
    "Convert the company-quick-access-keys to the candidates' row
NUMBER visible on the tooltip,
     and then feed it to `company-complete-number' to quickly select
and insert company candidates.
     If the currently entered character is belongs to
company-quick-access-keys and a part of the candidate simultaneously,
     append it to the currently entered string to construct new company-prefix."
    (interactive)
    (let* ((k (this-command-keys))
           (re (concat "^" company-prefix k)))
      (if (cl-find-if (lambda (s) (string-match re s))
                      company-candidates)

      (self-insert-command 1)
        (company-complete-number
     (cond
      ((equal k "1") 1)
      ((equal k "2") 2)
      ((equal k "3") 3)
      ((equal k "4") 4)
      ((equal k "5") 5)
      ((equal k "6") 6)
      ((equal k "7") 7)
      ((equal k "8") 8)
      ((equal k "9") 9)
      ((equal k "0") 10)
      ((equal k "q") 11)
      ((equal k "w") 12)
      ((equal k "e") 13)
      ((equal k "r") 14)
      ((equal k "t") 15)
      ((equal k "y") 16))
     ))))

  (let ((map company-active-map))
    (mapc (lambda (x) (define-key map (format "%s" x) 'hz-company-number))
      '(0 1 2 3 4 5 6 7 8 9 q w e r t y))))

I have adopted the following method, which seems to be more efficient

```emacs-lisp
(use-package comany

           company-quick-access-keys '("1" "2" "3" "4" "5" "6" "7" "8"

  (defun hz-company-number ()
    "Convert the company-quick-access-keys to the candidates' row

     and then feed it to `company-complete-number' to quickly select
and insert company candidates.
     If the currently entered character is belongs to
company-quick-access-keys and a part of the candidate simultaneously,
     append it to the currently entered string to construct new company-prefix."
    (interactive)
    (let* ((k (this-command-keys))
           (re (concat "^" company-prefix k)))
      (if (cl-find-if (lambda (s) (string-match re s))
                      company-candidates)

Further improvement is the following configuration:

```emacs-lisp
(use-package company
   :bind
   (:map company-active-map
    ("<tab>" . company-search-candidates)
    ("<backtab>" . company-search-abort)
    ("SPC" . company-complete-selection)
    ("<return>" . company-abort)

    :map company-search-map
    ("<tab>" . company-search-candidates)
    ("<backtab>" . company-search-abort)
    ("SPC" . company-complete-selection)
    ("<return>" . company-abort))

  :config
  (setq company-tooltip-limit 15
      company-quick-access-keys '("1" "2" "3" "4" "5" "6" "7" "8" "9"
"0" "=" "\;" "\`" "\," "\/"))

   (defun hz-company-number ()
    "Convert the company-quick-access-keys to the candidates' row

     and then feed it to `company-complete-number' to quickly select

     If the currently entered character is belongs to
company-quick-access-keys and a part of the candidate simultaneously,
     append it to the currently entered string to construct new company-prefix."
    (interactive)
    (let* ((k (this-command-keys))
           (re (concat "^" company-prefix k)))
      (if (cl-find-if (lambda (s) (string-match re s))
                      company-candidates)

      (self-insert-command 1)
    (company-complete-number
     (cond
      ((equal k "1") 1)

I write tab "\t" and return "\r" but I don't know what the
difference is, if any ...

That doesn't look good to me, you can do
`string-to-number wither either
(string-to-number "9")
(string-to-number "0") I guess

Cl-loop for with i as an Iterator from 1 to 10 ...

Also put this in the `let' clause so can be reused by us

 If the currently entered character is one of the
company-quick-access-keys and a part of the candidates at the same
time,

OK. Agree with you.

I forgot to simplify the above section in the case of only using
digits as the company-quick-access-keys. The following should be
enough [1]:

    (company-complete-number
     (if (equal k "0")
             10
           (string-to-number k)))

Tried the following methods, but it didn't work:

  (let ((c-a-map company-active-map)
    (c-s-map company-search-map))

    (cl-loop for x in (number-sequence 0 9)
         do ((define-key c-a-map (format "%s" x) #'hz/company-complete-number)))
    (cl-loop for x in (number-sequence 0 9)
         do ((define-key c-s-map (format "%s" x) #'hz/company-complete-number)))
    )

(mod (string-to-number k) 10)
