Emacs configuration

GNU Emacs is not just a text editor, it’s the ultimate tool for productivity. This document contains my Emacs Configuration which is a main part of my workflow everyday.

I have tried Emacs just to deepen my knowledge and so that I am able to use Emacs from scratch. This really helped me build my Doom emacs config that I use everyday.

Startup performance

;; -*- lexical-binding: t; -*-

;; The default is 800 kilobytes.  Measured in bytes.
(setq gc-cons-threshold (* 50 1000 1000))

;; Profile emacs startup
(add-hook 'emacs-startup-hook
          (lambda ()
            (message "*** Emacs loaded in %s seconds with %d garbage collections."
                     (emacs-init-time "%.2f")
                     gcs-done)))

Native Compilation

Some options to improve experience on the native-comp branch of Emacs.

;; Silence compiler warnings as they can be pretty disruptive
(setq native-comp-async-report-warnings-errors nil)

;; Set the right directory to store the native comp cache
(add-to-list 'native-comp-eln-load-path (expand-file-name "eln-cache/" user-emacs-directory))

Package management

I manage my Emacs packages using package.el and use-package. I have an unless block making sure that use-package is always installed, and packages installed with use-package have :ensure t by default.

(require 'package)
(add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/") t)
(add-to-list 'package-archives '("gnu" . "https://elpa.gnu.org/packages/") t)
;; (add-to-list 'package-archives '("nongnu" . "https://elpa.nongnu.org/nongnu/") t)
(add-to-list 'package-archives '("org" . "https://orgmode.org/elpa/") t)

(package-initialize)
(unless package-archive-contents
  (package-refresh-contents))

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

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

Keep folders clean

Keep folders where we edit files clean of any file that emacs creates.

(use-package no-littering)
(setq auto-save-file-name-transforms
    `((".*" ,(no-littering-expand-var-file-name "auto-save/") t)))

General Configuration

User Interface

Making the interface more minimal.

(setq inhibit-startup-message t)

(tooltip-mode -1)        ; Disable tooltips
(menu-bar-mode -1)       ; Disable the menu bar
(tool-bar-mode -1)       ; Disable the tool bar
(scroll-bar-mode -1)     ; Disable the scrollbar
(setq visible-bell nil)  ; Visible bell disabled

(set-frame-parameter (selected-frame) 'alpha '(97 . 100))
(add-to-list 'default-frame-alist '(alpha . (90 . 90)))

Relative line numbers. Really helpful when using evil mode.

(column-number-mode)                           ; Enable column number
(global-display-line-numbers-mode t)           ; Enable line numbers
(menu-bar-display-line-numbers-mode 'relative) ; Make line numbers relative

Customize per mode

Remove line numbers in shell mode

(dolist (mode '(term-mode-hook
                eshell-mode-hook
                treemacs-mode-hook))
  (add-hook mode (lambda () (display-line-numbers-mode 0))))

Font

My font of choice often varies, but I keep coming back to JetBrains Mono. I alternate between Cantarell and Overpass for my variable space fonts.

(defun ha/setup-font-main ()
  (set-face-attribute 'default nil :font "JetBrainsMono Nerd Font" :height 125 :weight 'light)
  (set-face-attribute 'fixed-pitch nil :font "JetBrainsMono Nerd Font" :height 125 :weight 'light)
  (set-face-attribute 'variable-pitch nil :font "Iosevka Aile" :height 140 :weight 'light))

Using all-the-icons for pretty icons.

(use-package all-the-icons
  :ensure t)

Rainbow delimiters. (attached on any buffer with programming mode)

(use-package rainbow-delimiters
  :hook (prog-mode . rainbow-delimiters-mode))

Theme

I like to use doom themes and occasionally the included themes.

(use-package doom-themes
  :config
  (load-theme 'doom-palenight t))

Doom modeline

(use-package doom-modeline
  :ensure t
  :init (doom-modeline-mode 1)
  :custom (
    (doom-modeline-height 40)
    (doom-modeline-battery t)))

Keybind panel

I am using which-key that helps me discover new keybinds and provides a pretty way to rediscover my keybinds.

(use-package which-key
  :defer 0
  ;; :init (which-key-mode)
  :diminish which-key-mode
  :config
  (which-key-mode)
  (setq which-key-idle-delay 0.3))

Ivy and Counsel

Ivy is my choice of completion engine for Emacs. Counsel gives me some commands such as counsel-find-file replacing emacs find-file with a much nicer minibuffer(ivy). Ivy-rich adds extra information to a few Counsel commands.

(use-package swiper)
(use-package ivy
  :diminish
  :bind (("C-s" . swiper)
         :map ivy-minibuffer-map
         ("TAB" . ivy-alt-done)
         ("C-l" . ivy-alt-done)
         ("C-j" . ivy-next-line)
         ("C-k" . ivy-previous-line))
  :config
  (ivy-mode 1))
(use-package counsel
  :bind(("M-x" . counsel-M-x)
        ("C-x b" . counsel-ibuffer)
        ("C-x C-f" . counsel-find-file))
  :config
  (setq ivy-initial-inputs-alist nil))

(use-package ivy-rich
  :after ivy
  :init
  (ivy-rich-mode 1))

Keyboard bindings

Escape all

This makes the escape key quit the minibuffer.

(global-set-key (kbd "<escape>") 'keyboard-escape-quit)

Evil time

(use-package evil
  :init
  (setq evil-want-integration t)
  (setq evil-keybinding t)
  (setq evil-want-keybinding nil)
  (setq evil-want-C-u-scroll t)
  :config
  (evil-mode 1)
  (evil-global-set-key 'motion "j" 'evil-next-visual-line)
  (evil-global-set-key 'motion "k" 'evil-previous-visual-line)
  (evil-set-initial-state 'messages-buffer-mode 'normal)
  (evil-set-initial-state 'dashboard-mode 'normal))

Evil collection package to enhance our evil :smilingimp: experience.

(use-package evil-collection
    :after evil
    :config
    (evil-collection-init))

Leader keybinds

Easy leader keymaps using general.el.

(use-package general

  (general-create-definer ha/leader-keys
    :keymaps '(normal insert visual emacs)
    :prefix "SPC"
    :global-prefix "C-SPC"))

Productivity

Workspaces with persp-mode

I like having workspaces as I often will have to quickly switch projects. Without having kill my other buffers, e.g. allows me to seperate my notes from my projects. TODO: Setup doom emacs like workspaces

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

(ha/leader-keys
 "TAB"  '(:ignore t :which-key "workspaces")
 "TAB n" '(persp-add-new :which-key "add")
)

Dashboard

I think a cool dashboard makes me open emacs more and do work :)

(use-package dashboard
  :config
  (dashboard-setup-startup-hook))

;; Make dashboard the default buffer in emacsclient
(setq initial-buffer-choice (lambda () (get-buffer "*dashboard*")))

Highlight TODO

Highlight keywords like TODO, FIXME, etc.

(use-package hl-todo
  :hook ((prog-mode . hl-todo-mode) (org-mode . hl-todo-mode))
  :config
  (setq hl-todo-highlight-punctuation ":"
        hl-todo-keyword-faces
        `(("TODO"        warning bold)
          ("FIXME"       error bold)
          ("HACK"        font-lock-constant-face bold)
          ("REVIEW"      font-lock-keyword-face bold)
          ("NOTE"        success bold)
          ("DEPRECATED"  font-lock-doc-face bold))))

Runtime performance

Dial the GC threshold back down so GC happens more frequently but in less time.

(setq gc-cons-threshold (* 2 1000 1000))

After frame hooks

For some reason, my emacs running in daemon mode fails to render the correct fonts.

;; Main fonts
(add-hook 'after-init-hook 'ha/setup-font-main)
(add-hook 'server-after-make-frame-hook 'ha/setup-font-main)
;; Fonts in org mode
(add-hook 'after-init-hook 'ha/org-font-setup)
(add-hook 'server-after-make-frame-hook 'ha/org-font-setup)
