Tabnine.el

Tabnine is a minor mode for the tabnine completion engine.

Warning: This Tabnine minor mode is unofficial, to fully exploit this minor mode you need a Tabnine pro account as the main reason for creating this minor mode is to make multi-line completions available in EMACS.

Note: Currently this is only supported on Linux and all configurations below are for Doom, this has only been tested with doom.

Installation

Ensure that you are using Emacs 28 with Doom

Add to packages.el

(package! tabnine 
    :recipe (:host github :repo "st1971/tabnine-mode"))

Configure doom

Configure copilot in ~/.doom.d/config.el:

;; Remove tab and shift tab from company mapping
(map! :after company
      :map company-active-map
      "TAB" nil
      "<tab>" nil
      "S-TAB" nil
      "S-<tab>" nil)

;; accept completion from copilot and fallback to company
(map! :after tabnine
      :map tabnine-active-map
      "C-g" #'tabnine-abort
      "<tab>" #'tabnine-next-completion
      "C-<tab>" #'tabnine-accept-completion
      )
      
;; add hook to automatically enable in modes
(add-hook! 'java-mode-hook (tabnine-mode 1))

Strongly recommend to enable childframe option in company module ((company +childframe)) to prevent overlay conflict.

These projects helped me a lot, without them this would have been impossible for me to create:
