For Python coding I use Elpy package which uses Company as completion framework.
Since I don't like automatic pop-ups I set my completion function to execute only when I explicitly ask for the completion suggestions with C-n keybinding. Unfortunately the setting for disabling a pop-up completion window is not working after pressing class member access operators such as ., ->, ::.
After looking through company-mode settings I found that company-semantic and company-clang have a toggle for switching on and off the automatic completion window. I set those to nil, but unfortunately there is no change in the behaviour. I used both 'customize' panel and manual assignment in the config.
Here is my config:
(use-package company
:ensure t
:hook (prog-mode . company-mode)
:config
(setq company-idle-delay nil ;; works as expected, completion is not invoked
company-semantic-begin-after-member-access nil ;; still pops-up, no change :(
company-clang-begin-after-member-access nil ;; no change either :(
company-minimum-prefix-length 3
company-selection-wrap-length 1
company-selection-wrap-around t)
(evil-collection-define-key 'insert 'company-mode-map
(kbd "C-n") 'company-complete)) ;; invokes completion manually
And example picture showing spot where this issue occurs:
