Add other modules

(add-to-list 'load-path (expand-file-name "modules/" user-emacs-directory))

Edit options

Whitespace clean

(add-hook 'before-save-hook #'whitespace-cleanup)

Tabs

(setq-default indent-tabs-mode nil)
(setq-default tab-width 4)

협업에 있어서 코드에 tabs 크기를 명시하는 것도 방법일듯.

Modeline Indentation example

• Emacs

  /* -*- Mode: rust; tab-width: 4; indent-tabs-mode: t; c-basic-offset: 4 -*- */

• Vim

  # Embeded VIM Configurations
  # vim: filetype=sh noet sw=4 ts=4 fdm=marker

• Visual Studio Code install extension modeline.

  // vim: set ft=js ts=4 sw=4 et:
  // vim :ts=4 :sw=4 :et :ft=js
  // -*- mode: js; indent-tabs-mode: nil; tab-width: 4 -*-
  // code: language=rust insertSpaces=false tabSize=4
