Init

Startup hook

;;; init.el -*- lexical-binding: t; -*-
(add-hook 'emacs-startup-hook
          (lambda ()
            (message "Emacs loaded in %s"
                     (emacs-init-time))))

Package Function

  (defvar bootstrap-version)
  (defvar comp-deferred-compilation-deny-list ()) ; workaround, otherwise straight shits itself
  (let ((bootstrap-file
         (expand-file-name "straight/repos/straight.el/bootstrap.el" user-emacs-directory))

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
  

Backup options

(setq backup-directory-alist `(("." . ,(expand-file-name "backups/" user-emacs-directory))))
(setq-default custom-file (expand-file-name ".custom.el" user-emacs-directory))

      trash-directory "~/.local/share/Trash/files/")
(setq undo-limit 100000000
      auto-save-default t)

Other options

  (set-default-coding-systems 'utf-8)
  (set-language-environment "utf-8")
  (prefer-coding-system 'utf-8)
  (customize-set-variable 'large-file-warning-threshold 100000000) ;; 100MB
