# Lowkey emacs setup bits and bobs

Nov 18, 2022
emacs

About a month ago I was a little bored and thought I’d give emacs a go. There’s something fun about trying out these mythical pieces of software that have been around forever; kind of like watching The Godfather for the first time. Like many extensible, super configurable programs, emacs seems kind of impenetrable at first glance. I tried doing the tutorial but kind of glazed over after a while with the endless stream of C-a C-b C-c. There’s also the quite jarring default theme which wasn’t vibing with the lovely screenshots I had seen on the internet. Anyway, after quite a bit of fiddling I’ve landed on a simple little setup that I’ve been quite enjoying. Here are a few little pointers to hopefully ease you in.

### AESTHETIC NICETIES

First things first, assuming you’re on linux emacs is configured with a file at `~/.emacs.d/init.el`. As a terrible aesthete, the first thing I was worried about was changing the theme. This can be achieved with `M-x load-theme`; if you want the setting to persist though you can add this to you init.el:

    (load-theme 'misterioso t)

There are a few themes out of the box but if you’re looking for some more I would recomment the doom-themes package. Speaking of packages, emacs has a built in package-manager that installs packages from the Emacs Lisp Package Archive (GNU ELPA); I unfortunately know very little about this as I’ve been using nix to manage my emacs packages.

Anyway we’ve got a theme, how about a custom startup message for our initial buffer:

    (setq inhibit-startup-message t
          inhibit-startup-echo-area-message t
          initial-scratch-message
          ";;oh how i adore to edit text with emacs!")

Maybe you dont want those big old cumbersome toolbars cluttering up your screen:

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

Perhaps some line highlighting and numbering:

    ;;line numbering
    (global-display-line-numbers-mode)
    (setq display-line-numbers-type 'relative)

    ;;line higlight
    (global-hl-line-mode t)

Custom font?

    (setq default-frame-alist '((font . "agave Nerd Font 14")))

### CUSTOM KEYBINDINGS AND EVIL

I don’t know if it’s just sunk cost fallacy or what but having gone to the trouble of learning to some extent how vim works, I kind of feel incomplete without vim keybindings now. Fortunately, emacs has evil mode which effectively emulates vim modal editing in emacs. To configure evil in our init.el we’ll use use-package. This is a macro which - to my understanding - talks to your package manager allowing you to configure installed packages in a nice neat efficient manner. To enable it, add this to your init.el:

    (eval-when-compile
      (require 'use-package))

These are the keybindings that I currently have going; nothing too crazy just a few simple things:

    (use-package evil
      :config
      (evil-mode 1)
      (evil-select-search-module 'evil-search-module 'evil-search)

      ;;manage panes
      (define-key evil-normal-state-map (kbd "M-s") 'evil-window-split)
      (define-key evil-normal-state-map (kbd "M-v") 'evil-window-vsplit)

      (define-key evil-normal-state-map (kbd "M-h") 'evil-window-left)
      (define-key evil-normal-state-map (kbd "M-j") 'evil-window-down)
      (define-key evil-normal-state-map (kbd "M-k") 'evil-window-up)
      (define-key evil-normal-state-map (kbd "M-l") 'evil-window-right)

      ;;get files open quick
      (define-key evil-normal-state-map (kbd "M-f") 'find-file)
      (define-key evil-normal-state-map (kbd "M-b") 'dired-jump)

      ;;terminal
      (define-key evil-normal-state-map (kbd "M-t") 'ansi-term)

      ;;nav buffers
      (define-key evil-normal-state-map (kbd "M-,") (kbd "C-x <left>"))
      (define-key evil-normal-state-map (kbd "M-.") (kbd "C-x <right>"))
      )

### SOME FRIEDNLY IDE FEATURES YOU MAY LIKE

I don’t know about you but having used vscode here and there I’ve become accustomed to a lot of these little IDE crutches (completion, autopair and the like) and now when I don’t have thme I feel a little sad. Emacs has it covered though as long as you’re happy with installing some additional stuff. Auto-completion? Try company:

    ;; enable company in all buffers
    (add-hook 'after-init-hook 'global-company-mode)
    (use-package company
      :commands company-tng-configure-default
      :custom
      ;; delay to start completion
      (company-idle-delay 0)
      ;; nb of chars before triggering completion
      (company-minimum-prefix-length 1)

You want the nice little autopair brackets?

    (use-package flex-autopair
      :config
      (flex-autopair-mode 1))

Clever commenting?

    (use-package smart-comment
      :bind ("M-c" . smart-comment))

Here’s a little pic of the current setup :)
