The first cond clause looks good but I don't see why you need the
t-clause? Isn't the thing that company-ispell is part of the default
value of the company-tabnine entry of company-backends? If that's the
case, you want to make company-backends buffer-local and remove it in
emacs-lisp-mode and derived modes but there is no need to add it again
otherwise because the default value won't be altered. So that'd be:
--8<---------------cut here---------------start------------->8---
(defun hz/company-tabnine-remove-company-ispell ()
(when (derived-mode-p 'emacs-lisp-mode)
(make-local-variable 'company-backends))
(setf (alist-get 'company-tabnine company-backends)
(remove 'company-ispell
(alist-get 'company-tabnine company-backends))))
--8<---------------cut here---------------end--------------->8---
But most importantly, `emacs-startup-hook' is not the one you want.
That runs once after emacs has loaded the init file. I'm even not sure
what buffer is current then. I guess the most logical hook is
`company-mode-hook'.
(add-hook 'company-mode-hook
#'hz/company-tabnine-remove-company-ispell)
Or maybe there is also some `company-tabnine-*-hook' that runs after
that package has done its setup in a buffer?
Bye,
Tassilo
