Emacs Configuration

Summary

Welcome to answer’s special Emacs configuration! I will customize this however I see fit to my advantage in the future. However, it is now a great step that I have made the move over to a configuration written within org-mode so that it is more organized.

Packages

Repositories

(require 'package)
(setq package-enable-at-startup nil)

(setq package-archives '(("ELPA"  . "http://tromey.com/elpa/")
                         ("gnu"   . "http://elpa.gnu.org/packages/")
                         ("melpa" . "https://melpa.org/packages/")
                         ("org"   . "https://orgmode.org/elpa/")))
(package-initialize)

use-package

Installation

(unless (package-installed-p 'use-package)
  (package-refresh-contents)
  (package-install 'use-package))

Enable ensuring of all packages listed to be automatically installed

Since repeating :ensure t is tiring, let’s make doing that redundant.

(require 'use-package-ensure)
(setq use-package-always-ensure t)

Automatically update packages

(use-package auto-package-update
  :config
  (setq auto-package-update-delete-old-versions t)
  (setq auto-package-update-hide-results t)
  (auto-package-update-maybe))

External Software Support

Windows

GPG

This allows us to have encrypted files in Emacs for things like schedules and other personal private data that somebody might want to look at.

(require 'epa-file)
(custom-set-variables '(epg-gpg-program "C:/Program Files (x86)/gnupg/bin/gpg.exe"))
(epa-file-enable)

Visual

Remove clutter from screen

(scroll-bar-mode -1)
(tool-bar-mode -1)
(menu-bar-mode -1)

Remove annoying noises from doing anything out of line

I know this doesn’t count as visual, but I really don’t feel like making a seperate category for this one thing.

(setq ring-bell-function 'ignore)

Font

DejaVu Sans Mono is a pretty reliable font that works for almost any situation comfortably.

(add-to-list 'default-frame-alist '(font . "DejaVu Sans Mono-10"))
(set-face-attribute 'default t :font "DejaVu Sans Mono-10")
(set-face-attribute 'default nil :font "DejaVu Sans Mono-10")
(set-frame-font "DejaVu Sans Mono-10" nil t)

Theme

(use-package dracula-theme
  :config (load-theme 'dracula t))

all-the-icons

(use-package all-the-icons)

Line numbers

Note taken on [2019-11-04 Mon 08:27]
This has been disabled since the line numbers take up a lot of space on the screen which the job of knowing which line number I’m on is solved by the modeline.

This enables line numbers in all programming related modes.

;; (add-hook 'prog-mode-hook 'display-line-numbers-mode)

Highlight current line in programming modes

The reason why we only do this when we have a window system is that highlight line mode can be a little broken without one.

(when window-system (add-hook 'prog-mode-hook 'hl-line-mode))

Rainbow Delimiters

(use-package rainbow-delimiters
  :ensure t
  :config (add-hook 'prog-mode-hook 'rainbow-delimiters-mode))

Beacon

(use-package beacon
  :config (beacon-mode 1))

Modeline

(use-package smart-mode-line
  :config
  (setq sml/theme 'respectful)
  (sml/setup))

Projectile

(use-package projectile
  :diminish projectile-mode
  :config
  (projectile-mode +1)
  (define-key projectile-mode-map (kbd "C-c p") 'projectile-command-map))

Dashboard

Page break lines

Needed to insert break lines so that ^L isn’t displayed instead.

(use-package page-break-lines)

Dashboard setup

(use-package dashboard
  :ensure t
  :init 
  :config
  (dashboard-setup-startup-hook)
  (setq dashboard-items '((recents . 5)
                          (bookmarks . 5)
                          (projects . 5)
                          (agenda . 5)))
  (setq dashboard-set-heading-icons t)
  (setq dashboard-set-file-icons t)
  (setq dashboard-startup-banner "~/.emacs.d/ralsei.png")
  (setq dashboard-set-footer nil)
  (setq dashboard-banner-logo-title "hewwo there OwO")
  (setq initial-buffer-choice (lambda () (get-buffer "*dashboard*"))))

Autocomplete

(use-package auto-complete
  :diminish
  :config (ac-config-default))

(ido-mode t)

IDO vertical mode

(use-package ido-vertical-mode
  :config
  (ido-vertical-mode 1)
  (setq ido-vertical-define-keys 'C-n-and-C-p-only))

popup-kill-ring

(use-package popup-kill-ring
  :bind ("M-y" . popup-kill-ring))

which-key

When we start a key macro, this helps gives us suggestions for what we can do in case we forgot what we were going to do.

(use-package which-key
  :diminish which-key-mode
  :config (which-key-mode))

Org

HTML-ize

Allow for the exporting of org-mode files in HTML in Windows.

  :ensure t)

               (visual-line-mode 1)))
