Known Issues

• company-transformers

  or plugins that use it (such as

  company-flx-mode

  ) can interfere with TabNine's sorting. If this happens, put the following temporary workaround in your config:

  ;; workaround for company-transformers
  (setq company-tabnine--disable-next-transform nil)
  (defun my-company--transform-candidates (func &rest args)
    (if (not company-tabnine--disable-next-transform)
        (apply func args)
      (setq company-tabnine--disable-next-transform nil)
      (car args)))
  
  (defun my-company-tabnine (func &rest args)
    (when (eq (car args) 'candidates)
      (setq company-tabnine--disable-next-transform t))
    (apply func args))
  (advice-add #'company--transform-candidates :around #'my-company--transform-candidates)
  (advice-add #'company-tabnine :around #'my-company-tabnine)

• TabNine's local deep learning completion might be enabled by default. It is very CPU-intensive if your device can't handle it. You can check by typing "TabNine::config" in any buffer (your browser should then automatically open to TabNine's config page) and disable Deep TabNine Local (you will lose local deep learning completion).
