* Package Bootstrapping
|
|
MELPA is a must for any Emacs configuration, it houses nearly everything you'd need related to Emacs. =use-package= is a useful macro for installing and configuring local remote packages.
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
;; Add MELPA to the repositories list
|
|
(require 'package)
|
|
(add-to-list 'package-archives
|
|
'("melpa" . "https://melpa.org/packages/") t)
|
|
|
|
;; Load packages list
|
|
(package-initialize)
|
|
|
|
;; Setup `use-package'
|
|
(unless (package-installed-p 'use-package)
|
|
(package-refresh-contents)
|
|
(package-install 'use-package))
|
|
(eval-when-compile
|
|
(require 'use-package))

|
|
* Look and Feel
|
|
I tend to like having a clean and unobtrusive interface, so I disable most of the UI elements. Switching to a visual-only bell is also essential; the audio one is quite annoying.
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
;; Set the theme
|
|
(use-package ample-theme
|
|
:ensure t
|
|
:config (load-theme 'ample t))
|
|
|
|
;; Disable menu bar
|
|
(menu-bar-mode -1)
|
|
|
|
;; Disable tool bar
|
|
(tool-bar-mode -1)
|
|

;; Disable scroll bars
|

|
|
(setq inhibit-startup-screen t)
|
|
|
|
;; Display line numbers
|
|
(global-display-line-numbers-mode 1)
|
|
(setq-default display-line-numbers-width 3)
|
|
|
|

|
|
(global-hl-line-mode 1)
|
|
|
|
;; Show trailing whitespace
|
|
(setq-default show-trailing-whitespace t)
|
|
|
|
;; Flash mode line on bell
|
|
(use-package mode-line-bell
|

:ensure t
|

:config (mode-line-bell-mode))

|
* Input and Text Manipulation
|
|
Useful options and packages for manipulating text, including the almighty Evil mode, which emulates Vi-style bindings. I also use these bindings in other modes, such as Dired and Org.
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
;; Better mouse scrolling
|
|
(setq mouse-wheel-progressive-speed nil)
|
|
|
|
;; Auto-pair parenthesis
|
|
(electric-pair-mode 1)
|
|
|
|
;; Automatically trim trailing whitespace on save
|
|
(add-hook 'before-save-hook 'delete-trailing-whitespace)
|
|
|
|
;;; VIM emulation
|
|
(use-package evil
|
|
:ensure t
|
|
:init
|
|
(setq
|
|
;; Scroll up with C-u
|
|
evil-want-C-u-scroll t
|

;; Yank to EOL with Y

|
|
:config (evil-mode))
|
|
|
|
;; General extension for Evil
|
|
(use-package evil-collection
|
|
:ensure t
|
|
:after evil
|
|
:config
|
|
(setq evil-collection-mode-list '(dired ibuffer))
|

(evil-collection-init))
|
|
|
|
;; Org extension for Evil
|
|
(use-package evil-org
|

:ensure t

#+END_SRC

|
* General Interface Improvements
|
|
I consider Vertico to be essential, as I find it to be a superior completion UI over the default one. Orderless is also very convenient as a completion style. Consult is very useful for searching through your buffers.
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
;; Use short yes/no answers
|
|
(setq-default use-short-answers t)
|
|
|
|
;;; Completion UI
|
|
(use-package vertico
|
|
:ensure t
|
|
:config
|
|
(vertico-mode)
|
|
;; Improve directory navigation
|
|
(define-key vertico-map (kbd "RET") #'vertico-directory-enter)
|
|
(define-key vertico-map (kbd "DEL") #'vertico-directory-delete-word)
|
|
(define-key vertico-map (kbd "M-d") #'vertico-directory-delete-char))
|
|
|
|
;;; Completion style
|
|
(use-package orderless
|
|
:ensure t
|
|
:config
|
|
(setq completion-styles '(orderless basic)
|
|
completion-category-overrides '((file (styles basic partial-completion)))))
|
|
|
|
;;; Extended completion utilities
|
|
(use-package consult
|
|
:ensure t
|
|
:config
|
|
(global-set-key [rebind switch-to-buffer] #'consult-buffer)
|
|
(global-set-key (kbd "C-c j") #'consult-line)
|

(global-set-key (kbd "C-c i") #'consult-imenu))
|

|
;; Completion options

completion-ignore-case t)

#+END_SRC

|
|
|
* Programming Extensions
|
|
Adding support for LSP, enabling static analysis, pop-up completions, Git integration, and other major modes not included by default.
|

Anything else that doesn't fit the bill.
