counsel-at-point for generic completion at point

[ghost]

I reconstituted these snippets from your dotfiles. Are these right?

(require 'python)
(define-key python-mode-map (kbd "C-M-i") 'counsel-jedi)

(require 'lisp-mode)
(define-key lisp-mode-map (kbd "C-M-i") 'counsel-cl)

(require 'clojure-mode)
(define-key clojure-mode-map (kbd "C-M-i") 'counsel-clj)

(define-key lisp-mode-shared-map "C-M-i" 'counsel-el)
;; or maybe
(define-key emacs-lisp-mode-map "C-M-i" 'counsel-el)

And maybe as well

(define-key org-mode-map (kbd "C-c C-q") 'counsel-org-tag)

Such snippets could either be added to the wiki or the readme snippet. But what would be really great would be a generic completion method, like ido-at-point, which would complete symbol at point with ivy using built-in completion system or the counsel-* completions functions if dependencies are available.

It may not require much changes to this package, since using it and re-defining this function worked for me:

(defun ido-at-point-read (comps common)
  (completing-read "" comps nil t common))

(ido-at-point-mode 1)

ivy-completing-read worked as well.

Thank you for your attention and awesome completion system!

[EDIT] Oh, and no hurry of course, this is a suggestion and not a request!

[abo-abo]

Thanks, I'll work on this in the future. I've been meaning to write a completion-in-region-function for some time now.

[ghost]

Glad to hear it! Closing the issue for now.

[abo-abo]

OK, ivy-mode now does in addition what ido-at-point does.

So counsel-el can be replaced with completion-at-point when ivy-mode is active.

However, I haven't yet figured out how to hook e.g. counsel-jedi into completion-at-point. Probably it should be the responsibility of (jedi:setup).

[ghost]

Oh, that is great news, thank you!
Ivy is amazing: with 20 more lines, I can remove a package!

I do not know how jedi is usually integrated with complenion systems.

Maybe company and autocomplete implementations could help.

Both seems to use jedi-core as a basis.

Maybe you have seen all of this already.

[ghost]

Yes, by looking at the sources, you are already aware of it! ^^

[s-kostyaev]

What do you think about counsel-company? Counsel may be very good frontend for company like helm-company.

[abo-abo]

@s-kostyaev Have a look.

[s-kostyaev]

@abo-abo Thanks. Looks good. Can you also add action for showing docs for candidates? I don't know how it works in company, but helm-company can't do this. Wait for new melpa build.

[s-kostyaev]

@abo-abo for me very useful something like this:

(defun counsel-company ()
  "Complete using `company-candidates'."
  (interactive)
  (unless company-candidates
    (company-complete))
  (when company-point
    (company-complete-common)
    (when (looking-back company-common (line-beginning-position))
      (setq ivy-completion-beg (match-beginning 0))
      (setq ivy-completion-end (match-end 0)))
    (ivy-read "company cand: " (mapcar (lambda (x)
                                         (concat
                                          x
                                          "\t\t"
                                          (company-call-backend 'annotation x)))
                                       company-candidates)
              :action (lambda (x)
                        (ivy-completion-in-region-action
                         (replace-regexp-in-string "\t\t\.*" "" x))
                        (run-at-time 0.01 nil 'company-pseudo-tooltip-hide)))))

But I think that annotation should have another face. May be need some defcustom for customize that.

[s-kostyaev]

I think adding annotations (with correct face) must be done by transformer, but my transformer does not work for now:

(defun counsel-company-transformer (str)
  "Add highlighted annotation into STR."
  (let ((annotation (company-call-backend 'annotation str))
    (set-text-properties 1 (length annotation) '(face success) annotation)
    (concat str "\t\t" annotation))))

(ivy-set-display-transformer 'counsel-company 'counsel-company-transformer)

@s-kostyaev Could you please open a new issue with the above two code snippets? I don't have time right now to deal with them, but I don't want to forget about it. An open issue helps to track it, but I don't want to re-open this one.

[s-kostyaev]

@abo-abo done.

[NightMachinery]

@s-kostyaev Where is the new issue you opened about showing docs with counsel-company?
