Evil-mode + company-mode C-n to cycle-through completion is unreliable.

[Kazimazi]

Describing the problem

I use C-n and C-p to cycle through completion and it becomes very unreliable.
I'm looking for some assistance how I could go about fixing it.

Since my explanation might not be clear I provide a video.

Expected behavior

Completion menu could be cycled perfectly, just like with M-n and M-p.

Actual behavior

After a few successful steps in the completion menu unexpected letters get into the completion and company pop-up menu eventually closes.

Steps to reproduce the problem

I made a minimal init file which has use-package, evil, company, clojure and cider-modes:

(require 'package)
(add-to-list 'package-archives
             '("melpa" . "https://melpa.org/packages/"))
(package-initialize)

(unless (package-installed-p 'use-package)
  (package-refresh-contents)
  (package-install 'use-package))
(eval-when-compile
  (require 'use-package))

(use-package evil :ensure t
  :config
  (evil-mode 1))

(use-package company :ensure t
  :demand t
  :bind (("C-SPC" . company-search-candidates)
         :map company-active-map
         ("C-p" . company-select-previous)
         ("C-n" . company-select-next)
         :map company-search-map
         ("C-p" . company-select-previous)
         ("C-n" . company-select-next))
  :init
  (setq company-minimum-prefix-length 1
        company-idle-delay 0.0)
  :config (global-company-mode +1))

(use-package clojure-mode :ensure t :defer t)

(use-package cider :ensure t :defer t)

emacs -q -l .config/emacs/init-minimal.el
Start typing something and press C-n several times.

[mizlan]

I have a similar issue where evil thinks I want to symbol completion (evil-complete-next and evil-complete-previous) when a company completion menu is visible.

[chrischambers]

I have the same issue as @mizlan and @Kazimazi - evil mode, company and cider don't seem to integrate nicely.

Some additional observations:

• Using ivy instead of orderless/selectrum and friends resolves the problem (presumably because it's not using the default emacs completion operations)
• I can sometimes get the correct behaviour by waiting for company-box to resolve - i.e. if I issue the commands slowly enough. This seems very inconsistent though: if I lower the company-box popup timer I can't get the company bindings to fire at all, the evil ones always take precedence.

[bbatsov]

I'll reopen the ticket, but as I don't use evil someone else will have to tackle the problem. I'm also not sure if that's some general problem with evil + company, or it's something specific to CIDER. (I know there are some problems with the current company backend that I'll have to fix at some point - #3006) //cc @dgutov

[dgutov]

If the behavior's different between C-n and M-n key bindings, the problem is likely somewhere in the Evil integration code -- and that resides inside Evil. Not much I could help there with.

If the issue can be reproduced without Evil, let me know.
