Using Emacs 45 - Company or Autocomplete

Comments

This is a good time to be an Emacs user. In addition to all of the great packages and tools being developed there seem to be more people regularly blogging and making videos about Emacs than ever before.

Planet Emacsen aggregates a ton of Emcas blogs and Emacs Legend Sacha Chua posts what's going on in emacs every week on her blog.

on the video front, uncle dave has recently joined the ranks of emacs video producers. sometimes we'll cover the same topic. dave made a video on swiper the other week and i made one a year ago. the other week we both made videos on mpd almost on the same day but dave focussed on emms and i focussed on simple-mpc. i think this is great because it gives different perspectives.

today, i watched dave's video on company mode for auto completion. I've always used autocomplete mode. I thought it would be a good time for me to see how the other half lived.

You can find my configurations up on GitHub (https://github.com/zamansky/using-emacs). The master branch is using autocomplete and the company-test branch for company. I've also pulled out the relevant code and am placing it down under the video.

Here's what I've found so far:

Company config (so far):

(use-package company
:ensure t
:config
(setq company-idle-delay 0)
(setq company-minimum-prefix-length 3)
(global-company-mode t))

(use-package company-irony
:ensure t
:config 
(add-to-list 'company-backends 'company-irony))

(use-package irony
:ensure t
:config
(add-hook 'c++-mode-hook 'irony-mode)
(add-hook 'c-mode-hook 'irony-mode)
(add-hook 'irony-mode-hook 'irony-cdb-autosetup-compile-options))

(use-package irony-eldoc
:ensure t
:config
(add-hook 'irony-mode-hook #'irony-eldoc))

(use-package company-jedi
    :ensure t
    :config
    (add-hook 'python-mode-hook 'jedi:setup))

(defun my/python-mode-hook ()
  (add-to-list 'company-backends 'company-jedi))

(add-hook 'python-mode-hook 'my/python-mode-hook)

Autocomplete config

(use-package auto-complete
:ensure t
:init
(progn
  (ac-config-default)
  (global-auto-complete-mode t)
  ))

(setq py-python-command "python3")
(setq python-shell-interpreter "python3")

  (use-package jedi
    :ensure t
    :init
    (add-hook 'python-mode-hook 'jedi:setup)
    (add-hook 'python-mode-hook 'jedi:ac-setup))
