My Emacs configuration file

Currently this is heavily based on the config file built in System Crafters's Emacs from Scratch playlist. If you have the time and interest, I highly recommend following along with it yourself instead of just copying.

;; Basic UI Configuration ------------------------------------------------------

;; You will most likely need to adjust this font size for your system!
(defvar runemacs/default-font-size 100)

(setq inhibit-startup-message t)

(scroll-bar-mode -1)        ; Disable visible scrollbar
(tool-bar-mode -1)          ; Disable the toolbar
(tooltip-mode -1)           ; Disable tooltips
(set-fringe-mode 10)        ; Give some breathing room

(menu-bar-mode -1)            ; Disable the menu bar

;; Set up the visible bell
(setq visible-bell t)

(column-number-mode)
(global-display-line-numbers-mode t)

;; Disable line numbers for some modes
(dolist (mode '(org-mode-hook
                term-mode-hook
                shell-mode-hook
                eshell-mode-hook))
  (add-hook mode (lambda () (display-line-numbers-mode 0))))

;; Font Configuration ----------------------------------------------------------

(set-face-attribute 'default nil :font "Fira Code Retina" :height runemacs/default-font-size)

;; Set the fixed pitch face
(set-face-attribute 'fixed-pitch nil :font "Fira Code Retina" :height 260)

;; Set the variable pitch face
(set-face-attribute 'variable-pitch nil :font "Cantarell" :height 120 :weight 'regular)

;; Package Manager Configuration -----------------------------------------------

;; Initialize package sources
(require 'package)

(setq package-archives '(("melpa" . "https://melpa.org/packages/")
                         ("org" . "https://orgmode.org/elpa/")
