Emacs configuration file

Credits

Inspired by freetonik’s setup.

Warnings

This config is not intended to be used by anyone other than me. I would not recommend using this configuration as-is.

Setup

Prerequisites

Install bear:

sudo apt-get install bear

Install wordnet, for example on Ubuntu:

sudo apt install wordnet

Install eslint_d eslint server, it is used as flycheck-javascript-eslint-executable:

npm i -g eslint_d

Install pdf-tools:

M-x pdf-tools-install RET

Check if pdf-tools are working:

M-x pdf-info-check-epdfinfo RET

Clone the repo:

git clone --recurse-submodules -j8 --depth=1 https://github.com/vyorkin/emacs.d

Make a backup of your old .emacs.d:

mv ~/.emacs.d ~/.emacs.d-bak

Symlink init.org to ~/.emacs.d/init.org
Symlink init.el to ~/.emacs.d/init.el

ln -sf $(pwd)/init.org ~/.emacs.d/init.org
ln -sf $(pwd)/init.el ~/.emacs.d/init.el

On the first run Emacs will install some packages. It’s best to restart Emacs after that process is done for the first time.

There is no reason to track the init.el that is generated; by running the following command git will not bother tracking it:

git update-index --assume-unchanged init.el

If one wishes to make changes to the repo-version of init.el start tracking again with:

git update-index --no-assume-unchanged init.el

When this configuration is loaded for the first time, the init.el is the file that is loaded. It looks like this:

;; We can't tangle without org!
(require 'org)
;; Open the configuration
(find-file (concat user-emacs-directory "init.org"))
;; Tangle it
(org-babel-tangle)
;; Load it
(load-file (concat user-emacs-directory "init.el"))
;; Finally byte-compile it
(byte-compile-file (concat user-emacs-directory "init.el"))

Check this init.org and run M-x all-the-icons-install-fonts if all-the-icons package is enabled.

This is a known issue with emacs 28:

Eager macro-expansion failure: (wrong-number-of-arguments (3 . 4) 2) [2 times]
define-obsolete-variable-alias: Wrong number of arguments: (3 . 4), 2

There a number of PRs that fixes it as of 14/02/2021. Update packages after some time to see if it is fixed.

Startup timer

(add-hook 'emacs-startup-hook
  (lambda ()
    (message
     "Emacs ready in %s with %d GC's."
     (format
      "%.2f seconds"
      (float-time (time-subtract after-init-time before-init-time)))
     gcs-done)))

Config

Intro

Lexical binding for the init-file is needed, it can be specified in the header. This is the first line of the actual configuration.

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

Make startup faster by reducing the frequency of garbage collection. The default is 800 kilobytes. Measured in bytes. These are the first lines of the actual configuration.

(setq gc-cons-threshold most-positive-fixnum)

In noninteractive sessions, prioritize non-byte-compiled source files to prevent the use of stale byte-code.

(setq load-prefer-newer noninteractive)

Non-nil means enter debugger if an error is signaled.

(setq debug-on-error t)

Customization

Let’s keep all customizations in one place.

Location

Location name and coordinates.

(defvar my/lat 55.84)
(defvar my/lon 37.34)
(defvar my/location "Moscow, RU")

Utils

Utility functions.

(defun my/emacs-path (path)
  "Expands `path` with Emacs home directory."
  (expand-file-name path user-emacs-directory))

(defun my/tmp-path (path)
  "Expand `path` with Emacs temporary directory."
  (my/emacs-path (format "tmp/%s" path)))

(defun my/lisp-path (path)
  "Expand `path` with Emacs `/lisp` directory."
  (my/emacs-path (format "lisp/%s" path)))

Auto-tangling (disabled)

I don’t use auto-tangling since I don’t want to tangle every time I save my init.org. Instead I call org-babel-tangle manually once at the very end of making changes.

Tangle and compile this file on save automatically:

(defun tangle-init ()
  "If the current buffer is 'init.org' the code-blocks are
tangled, and the tangled file is compiled."
  (when (equal (buffer-file-name)
               (file-truename (concat user-emacs-directory "init.org")))
    ;; Avoid running hooks when tangling.
    (let ((prog-mode-hook nil))
      (org-babel-tangle)
      (byte-compile-file (concat user-emacs-directory "init.el")))))

(add-hook 'after-save-hook 'tangle-init)

Package management

Init

Initialize package and add package archives.

(require 'package)

Tangle the following line if you have TLS-related issues:

(setq gnutls-algorithm-priority "NORMAL:-VERS-TLS1.3")

;; Try to uncomment this if you have TLS-related issues
;; (setq gnutls-algorithm-priority "NORMAL:-VERS-TLS1.3")

(let* ((no-ssl (and (memq system-type '(windows-nt ms-dos))
                    (not (gnutls-available-p))))
    (proto (if no-ssl "http" "https")))
    (add-to-list 'package-archives (cons "melpa" (concat proto "://melpa.org/packages/")) t))

It is ok to use both package-initialize and use-package for a well behaved package: package-initialize will not load the whole package, but only autoload functions selected by the package author.

(package-initialize)

Use-package

Install

Install use-package.

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

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

Config

Install missing packages automatically if not already present on the system and be less verbose.

(setq
 use-package-always-ensure t
 use-package-verbose nil)

Statistics gathering (disabled)

Enable tangling and run the M-x use-package-report command to see the results. Read the docs for more info.

(use-package-compute-statistics)

Quelpa

Setup quelpa.

(if (require 'quelpa nil t)
  ;; Prevent quelpa from doing anyting that requires network connection.
  (setq
   quelpa-update-melpa-p nil    ; Don't update MELPA git repo
   quelpa-checkout-melpa-p nil  ; Don't clone MELPA git repo
   quelpa-upgrade-p nil         ; Don't try to update packages automatically
   quelpa-self-upgrade-p nil)   ; Don't upgrade quelpa automatically

(unless (package-installed-p 'quelpa)
  (with-temp-buffer
    (url-insert-file-contents "https://github.com/quelpa/quelpa/raw/master/quelpa.el")
    (eval-buffer)
    ;; Comment/uncomment line below to disable/enable quelpa auto-upgrade.
    (quelpa-self-upgrade))))

Install use-package and the quelpa handler.

(quelpa
 '(quelpa-use-package
   :fetcher github
   :repo "quelpa/quelpa-use-package"))
(require 'quelpa-use-package)

Advice setting :ensure nil for use-package + quelpa.

(quelpa-use-package-activate-advice)

Use-package plugins

All credit to a13.

Works as :custom keyword, but instead of a value takes update function or the second (the first is the original one) argument to the default updater.

(use-package use-package-custom-update
 :quelpa
 (use-package-custom-update
   :repo "a13/use-package-custom-update"
   :fetcher github
   :version original))

:secret keyword for use-package.

(use-package use-package-secrets
 :custom
 (use-package-secrets-directories '("~/.emacs.d/secrets"))
 :quelpa
 (use-package-secrets
   :repo "a13/use-package-secrets"
   :fetcher github
   :version original))

System shell env

Pass system shell environment to Emacs. This is important primarily for shell inside Emacs, but also things like Org mode export to Tex PDF don’t work, since it relies on running external command pdflatex, which is loaded from PATH. Also this is required for use-package-ensure-system-package extension.

(use-package exec-path-from-shell
 :commands
 (exec-path-from-shell-copy-envs
  exec-path-from-shell-initialize)
 :init
 (setq exec-path-from-shell-check-startup-files nil)
 :config
 (exec-path-from-shell-copy-envs '("WAKATIME_API_KEY"))
 (when (memq window-system '(mac ns x))
   (exec-path-from-shell-initialize)))

Warnings

Decrease the obsolete warnings annoyance level.

(setq byte-compile-warnings '(not obsolete))

This helps to get rid of functions might not be defined at runtime warnings. See this issue for details.

(eval-when-compile
  (setq use-package-expand-minimally byte-compile-current-file))

Suppress ad-handle-definition warnings.

(setq ad-redefinition-action 'accept)

Defaults

Backups & lock files

Don’t create lock files.

(setq create-lockfiles nil)

I don’t care about auto save and backup files. Also I don’t like distracting alarms.

(setq
 make-backup-files nil        ; disable backup files
 auto-save-list-file-name nil ; disable .saves files
 auto-save-default nil        ; disable auto saving
 ring-bell-function 'ignore)  ; turn off alarms completely

Performance

Disable bidirectional text for a tiny performance boost.

(setq-default bidi-display-reordering nil)

Update UI less frequently (disabled).

(setq
 idle-update-delay 2
 jit-lock-defer-time 0
 jit-lock-stealth-time 0.2
 jit-lock-stealth-verbose nil)

Misc

Use y/n instead of yes/no.

(fset 'yes-or-no-p 'y-or-n-p)

Don’t prompt for non existent name when creating new buffers.

(setq-default confirm-nonexistent-file-or-buffer t)

Enable recentf-mode and remember a lot of files.

(setq
 recentf-auto-cleanup 'never
 recentf-max-menu-items 0
 recentf-max-saved-items 300
 recentf-filename-handlers '(file-truename abbreviate-file-name))

(recentf-mode 1)

Automatically save place in each file.

(setq
 save-place-forget-unreadable-files t
 save-place-limit 400)

(save-place-mode 1)

Location

Set the location name and coordinates.

(setq
 calendar-location-name my/location
 calendar-latitude my/lat
 calendar-longitude my/lon)

Builtin

Imports

(require 'color)

Files

On save/write file:

Automatically delete trailing whitespace.
Silently put a newline at the end of file if there isn’t already one there.

(use-package files
  :ensure nil
  :preface
  (defun my/files/setup ()
    (add-hook 'before-save-hook 'delete-trailing-whitespace))
  :commands
  (generate-new-buffer
   executable-find
   file-name-base
   file-name-extension)
  :custom
  (require-final-newline t)
  :hook
  (prog-mode . my/files/setup))

Reverting

Diminish autorevert mode.

(use-package autorevert
 :ensure nil
 :custom
 ;; Don't generate any messages whenever a buffer is reverted
 (auto-revert-verbose nil)
 ;; Operate only on file-visiting buffers
 (global-auto-revert-non-file-buffers t)
 :diminish auto-revert-mode)

Uniquify

The forward buffer name style includes part of the file’s directory name at the beginning of the buffer name. Using this method, buffers visiting the files /u/rms/tmp/Makefile and /usr/projects/hooy/Makefile would be named ‘tmp/Makefile’ and ‘hooy/Makefile’.

(use-package uniquify
 :ensure nil
 :custom
 ;; use "foo/bar/qux"
 (uniquify-buffer-name-style 'forward))

History

Many editors (e.g. Vim) have the feature of saving minibuffer history to an external file after exit. This package provides the same feature in Emacs. When set up, it saves recorded minibuffer histories to a file (~/.emacs-history by default).

(use-package savehist
  :ensure nil
  :custom
  (savehist-additional-variables
   '(kill-ring
     ;; search entries
     search-ring
     regexp-search-ring))
  ;; save every minute
  (savehist-autosave-interval 60)
  (savehist-save-minibuffer-history t)
  :init
  (savehist-mode 1))

Frame

Disable blinking cursor.
Disable suspending on C-z.

(use-package frame
 :ensure nil
 :config
 (blink-cursor-mode 0)
 :bind
 ("C-z" . nil))

Delsel

C-c C-g always quits minibuffer.

(use-package delsel
 :ensure nil
 :bind
 ("C-c C-g" . minibuffer-keyboard-quit))

Simple

(use-package simple
  :ensure nil
  :diminish
  ((visual-line-mode . " ↩")
   (auto-fill-function . " ↵"))
  :bind
  ;; remap ctrl-w/ctrl-h
  (("C-c h" . help-command)
   ("C-x C-k" . kill-region)
   ("C-h" . delete-backward-char)))

VC hooks

(use-package vc-hooks
  :ensure nil
  :config
  (setq
   vc-follow-symlinks t
   vc-make-backup-files nil))

Prog mode

Prettify symbols.

(use-package prog-mode
 :ensure nil
 :commands
 (global-prettify-symbols-mode)
 :init
 (setq prettify-symbols-unprettify-at-point 'right-edge)
 :config
 ;; convert certain words into symbols, e.g. lambda becomes λ.
 (global-prettify-symbols-mode t))

IBuffer

Use the ibuffer in place of the default list-buffers command. This provides tremendous amount of additional functionality in terms of filtering, grouping, and acting upon the listed buffers. Also, it opens the list of buffers in the same window.

(use-package ibuffer
 :ensure nil
 :bind
 ;; Set all global list-buffers bindings to use ibuffer
 ([remap list-buffers] . ibuffer))

Mule

(use-package mule
 :commands
 (set-terminal-coding-system)
 :ensure nil
 :config
 (prefer-coding-system 'utf-8)
 (set-terminal-coding-system 'utf-8)
 (set-language-environment "UTF-8"))

ETags

Setup Emacs tags.

(use-package etags
 :ensure nil
 :custom
 ;; Don't add a new tags to the current list.
 ;; Always start a new list.
 (tags-add-tables nil))

Man

(use-package man
 :ensure nil
 :custom-face
 (Man-overstrike ((t (:inherit font-lock-type-face :bold t))))
 (Man-underline ((t (:inherit font-lock-keyword-face :underline t)))))

Calendar

(use-package calendar
 :ensure nil
 :custom
 (calendar-week-start-day 1))

Face remap

(use-package face-remap
 :commands
 (buffer-face-mode-face
  face-remap-add-relative
  buffer-face-mode)
 :ensure nil
 :diminish buffer-face-mode)

CC mode

Note that “.m” conflicts with mercury-mode.

(use-package cc-mode
 :ensure nil
 :config
 ;; (add-to-list 'auto-mode-alist '("\\.m\\'" . objc-mode))
 (add-to-list 'auto-mode-alist '("\\.mm\\'" . objc-mode)))

Compile

Kill compilation process before starting another, save all buffers on compile, scroll to the first compilation error automatically.

(use-package compile
  :custom
  (compilation-always-kill t)
  (compilation-ask-about-save nil)
  (compilation-scroll-output t)
  :init
  (make-variable-buffer-local 'compile-command)
  (put 'compile-command 'safe-local-variable 'stringp))

Shell

Hide the “Indentation setup for shell type sh” message in the minibuffer.

(advice-add
 'sh-set-shell :around
 (lambda (orig-fun &rest args)
   (let ((inhibit-message t))
     (apply orig-fun args))))

Libraries

async

Simple library for asynchronous processing in Emacs.

(use-package async
  :demand t
  :config
  (autoload 'dired-async-mode "dired-async.el" nil t)
  (dired-async-mode 1)
  (async-bytecomp-package-mode 1))

alert

A Growl-like alerts notifier for Emacs.

(use-package alert)

UI

Basics

(setq
 inhibit-startup-screen t ; Don't show splash screen
 use-dialog-box nil       ; Disable dialog boxes
 use-file-dialog nil)     ; Disable file dialog

Titlebar

Make titlebar transparent.

(when (memq window-system '(mac ns))
  (add-to-list 'default-frame-alist '(ns-appearance . dark)) ;; {light, dark}
  (add-to-list 'default-frame-alist '(ns-transparent-titlebar . t)))

Scroll

More procedural scrolling.

(setq
 auto-window-vscroll nil
 hscroll-margin 5
 hscroll-step 5
 scroll-conservatively 101
 scroll-margin 0
 scroll-preserve-screen-position t)

(setq-default
 scroll-down-aggressively 0.01
 scroll-up-aggressively 0.01)

UI elements

Hide toolbar and scrollbars.

(tool-bar-mode -1)
(scroll-bar-mode -1)
(when (fboundp 'horizontal-scroll-bar-mode)
  (horizontal-scroll-bar-mode -1))

I generally prefer to hide the menu bar, but doing this on OS X simply makes it update unreliably in GUI frames, so we make an exception.

(if (eq system-type 'darwin)
    (add-hook 'after-make-frame-functions
              (lambda (frame)
                (set-frame-parameter frame 'menu-bar-lines
                                     (if (display-graphic-p frame) 1 0))))
  (when (fboundp 'menu-bar-mode)
    (menu-bar-mode -1)))

Don’t blink matching paren, it’s too distracting.

(setq-default blink-matching-paren nil)

Cursor

Hide cursor in inactive windows.

(setq-default cursor-in-non-selected-windows nil)

Display vertical bar cursor with default width.
Draw block cursor as wide as the glyph under it.

(setq-default
 cursor-type 'bar
 x-stretch-cursor t)

Show full path in the title bar.

(setq-default frame-title-format "%b (%f)")

Don’t implicitly resize the frame’s display area in order to preserve the number of columns or lines the frame displays when changing font, menu bar, tool bar, internal borders, fringes or scroll bars. Read this for more info.

(setq-default frame-inhibit-implied-resize t)

Fringe

Set fringe size.

(fringe-mode '(12 . 12))

Setup fringes on both sides and display an indicator for buffer boundaries on the left side. Display fringes outside margins to have the padding on the inside.

(setq-default
 fringes-outside-margins t
 left-fringe-width 8
 right-fringe-width 8
 indicate-buffer-boundaries 'left)

Remove continuation arrow on right fringe.

(setq-default
 fringe-indicator-alist
 (delq (assq 'continuation fringe-indicator-alist) fringe-indicator-alist))

Window-divider

Hide the window-divider (a line separating windows).

(when (boundp 'window-divider-mode)
  (setq window-divider-default-places t
        window-divider-default-bottom-width 0
        window-divider-default-right-width 0)
  (window-divider-mode +1))

Line-spacing

Non-zero values for line-spacing can mess up ansi-term and co, so we zero it explicitly in those cases.

(add-hook
 'term-mode-hook
 (lambda () (setq line-spacing 0)))

Highlight parens.

(setq show-paren-style 'parenthesis)
(show-paren-mode 1)

Treat an Emacs region much like a typical text selection outside of Emacs.

(setq delete-selection-mode t)

Set left and right margins for every window.

(setq-default
 left-margin-width 1
 right-margin-width 1)

Startup

Start maximized (disabled).

(toggle-frame-maximized)

Mode line

Turn-off tooltips on cursor hover-over.

(setq mode-line-default-help-echo nil)

Display only line and column in a mode-line.

(setq
 mode-line-position
 '((line-number-mode ("%l" (column-number-mode ":%c")))))

Time

(use-package time
  :ensure nil
  :custom
  (display-time-default-load-average nil)
  (display-time-24hr-format t)
  :config
  (display-time-mode t))

Font

  (set-fontset-font
   "fontset-default"
   'cyrillic
   (font-spec :registry "iso10646-1" :script 'cyrillic)))

Font lock

Try to speed-up font-lock-mode.

(setq
 font-lock-maximum-decoration
 '((c-mode . 2) (c++-mode . 1) (t . 1)))

(setq font-lock-support-mode 'jit-lock-mode)
(setq
 jit-lock-stealth-time 16
 jit-lock-defer-contextually t
 jit-lock-stealth-nice 0.5)

Editor

Customizations

I don’t use the customizations UI. Anyway, I keep those automated customizations in a separate file. The 'noerror argument passed to load prevents errors if the file doesn’t exist.

(setq custom-file (my/emacs-path "custom.el"))
(load custom-file 'noerror)

Basics

Some basic things.

(setq
 ;; sentences should end in one space
 sentence-end-double-space nil
 ;; empty scratch buffer
 initial-scratch-message nil
 ;; show keystrokes right away,
 ;; don't show the message in the scratch buffer
 echo-keystrokes 0.1
 ;; disable native fullscreen support
 ns-use-native-fullscreen nil)

Minibuffer

Give some more room to the minibuffer.

(setq
 max-mini-window-height 0.3
 resize-mini-windows 'grow-only)

Enable recursive minibuffers and keep the point out of the minibuffer.

(setq
 ;; allow minibuffer commands in the minibuffer
 enable-recursive-minibuffers t
 ;; keep the point out of the minibuffer
 minibuffer-prompt-properties
 '(read-only t point-entered minibuffer-avoid-prompt face minibuffer-prompt))

Auto executable scripts.

(add-hook 'after-save-hook #'executable-make-buffer-file-executable-if-script-p)

Tabs & spaces

Use spaces instead of tabs everywhere.
One tab is 2 spaces.

(setq-default
 indent-tabs-mode nil
 tab-width 2)

Display line and column numbers in the mode-line.

(setq
  line-number-mode t
  column-number-mode t)

Line wrapping

Long lines will show a continuation character in the right margin at the window’s edge to indicate that one can scroll to see the rest.

(setq-default truncate-lines t)

Break line at N characters.

(setq-default fill-column 64)

Enable automatic line breaking for all text mode buffers.

(add-hook 'text-mode-hook 'turn-on-auto-fill)

Always wrap lines.

Kurecolor

A collection of color tools aimed at those working with (normal 6 digit) hex color codes, useful for CSS, Emacs themes, etc. etc.

Features include interactive step modification of hue, sat, val on hex colors. Color conversion algorithms, for 6 digit hex colors, hsv, rgb, cssrgb. Get/set h s v values from/for a color.

It’s recommend you use this in conjunction with rainbow-mode, for instant feedback on color changes.

See the kurecolor github for more info.

Behavior

Garbage collection

Enforce a sneaky Garbage Collection strategy to minimize GC interference with the activity. During normal use a high GC threshold is set. When idling GC is immediately triggered and a low threshold is set.

A more detailed explanation of the rationale behind this can be found at: http://akrl.sdf.org/.

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

Server

Start server if one isn’t already running.

(use-package server
  :ensure nil
  :commands server-running-p
  :preface
  (defun my/server-ensure-running (frame)
    "Ensure server is running when launching FRAME."
    (with-selected-frame frame

Buffer

Hide async shell command buffers.

(cl-pushnew
 '("^*Async Shell Command*" . (display-buffer-no-window))
 display-buffer-alist
 :test #'equal)

Always display pop up buffers at the bottom and regard all star buffers as such buffers. (Not always that useful)

(let ((rule
       `(,(rx bos "*" (one-or-more anything) "*" (optional "<" (one-or-more anything) ">") eos)
         (display-buffer-reuse-window
          display-buffer-in-side-window)

 (global-page-break-lines-mode 1)
 :diminish page-break-lines-mode)

Rainbow delimiters

rainbow-delimiters is a “rainbow parentheses”-like mode which highlights delimiters such as parentheses, brackets or braces according to their depth. Each successive level is highlighted in a different color. This makes it easy to spot matching delimiters, orient yourself in the code, and tell which statements are at a given depth.

(use-package rainbow-delimiters
 :commands
 (rainbow-delimiters-unmatched-face)
 :config
 ;; Pastels
 (set-face-attribute 'rainbow-delimiters-depth-1-face nil :foreground "#78c5d6")

Rainbow identifiers

Rainbow identifier highlighting.

(use-package rainbow-identifiers
 :hook
 (prog-mode . rainbow-identifiers-mode)
 :diminish rainbow-identifiers-mode)

Rainbow mode (disabled)

This minor mode sets background color to strings that match color.

Disabled because it highlights things like #define MACROS.

(use-package rainbow-mode
 :diminish rainbow-mode
 :hook prog-mode
 :config
 (nmap
   :prefix my/leader

Line highlight

Provides a local minor mode (toggled by M-x hl-line-mode) and a global minor mode (toggled by M-x global-hl-line-mode) to highlight, on a suitable terminal, the line on which point is.

(use-package hl-line
  :custom
  ;; Only highlight in selected window
  (hl-line-sticky-flag nil)
  (global-hl-line-sticky-flag nil)

  (global-hl-line-mode)
  (nmap
    :prefix my/leader
    "t l" 'global-hl-line-mode))

Column highlight (slow)

Library required for the col-hightlight package.

(use-package vline
  :quelpa
  (vline :fetcher github :repo "emacsmirror/vline"))

This package highlights the current column. When you move the cursor, the highlighting follows (tracks the cursor), as long as the highlighting stays on.

(use-package col-highlight
  :after (vline)
  :quelpa
  (col-highlight :fetcher github :repo "emacsmirror/col-highlight")
  ;; :hook
  ;; (prog-mode . column-highlight-mode)
  :config
  (set-face-background 'col-highlight "#151515")
  (nmap
    :prefix my/leader
    "t c" 'column-highlight-mode))

Column marker

With this library you can highlight a column (vertical line) of text. In fact, you can highlight any number of such columns – 3 such highlight column markers are provided by default, but you can easily define more.

(use-package column-marker
  :quelpa
  (column-marker :fetcher github :repo "emacsmirror/column-marker"))

Hightlight todos

Moody + minions (gnu/linux-only)

Another option is moody + minions as an attractive minimalist mode line replacement.

Minions is a minor-mode menu for the mode line. This menu is intended as a replacement for the incomplete yet wide list of enabled minor-modes that is displayed in the mode line by default.

(use-package minions
 :if (eq system-type 'gnu/linux)
 :config
 (setq minions-mode-line-lighter "[+]")
 (minions-mode 1))

Provides utilities for displaying elements of the mode line as tabs and ribbons. It also provides replacements for a few built-in elements.

(use-package moody
 :if (eq system-type 'gnu/linux)
 :config
 (moody-replace-mode-line-buffer-identification)
 (moody-replace-vc-mode)

Multiple cursors

Provides multiple cursors functionality for Emacs when used with evil-mode.

(use-package evil-mc

Matchit

Vim matchit.vim by Benji Fisher is ported into Emacs.

Press “%” to jump between matched tags in Emacs. For example, in HTML “<div>” and “</div>” are a pair of tags. Many modern languages are supported.

(use-package evil-matchit
 :after evil
 :demand t
 :commands
 (evilmi-jump-items
  evilmi-text-object
  global-evil-matchit-mode)
 :config
 (global-evil-matchit-mode 1))

Smartparens

(use-package evil-smartparens
  :after (smartparens)
  :config
  (add-hook 'smartparens-enabled-hook #'evil-smartparens-mode))

String inflection

Evil operator to cycle text objects through camelCase, kebab-case, snake_case and UPPER_CASE.

The keybinding is g~. For example, try using g~io.

(use-package evil-string-inflection)

Surround

This package emulates surround.vim by Tim Pope. The functionality is wrapped into a minor mode.

This package uses Evil as its vi layer.

(use-package evil-surround
 :after evil
 :demand t
 :commands
 (global-evil-surround-mode
   evil-surround-edit
   evil-Surround-edit
   evil-surround-region)

Visualstar

This is a port of one of the many visual-star plugins for Vim to work with evil-mode.

(use-package evil-visualstar
 :after evil
 :commands
 (global-evil-visualstar-mode
   evil-visualstar/begin-search
   evil-visualstar/begin-search-forward
   evil-visualstar/begin-search-backward)
 :config
 (global-evil-visualstar-mode))

Vimish fold

Adds standard vim keybindings of zf and zd to create and delete folds (via vimish-fold) respectively. Also hooks into evil so the usual vim keybindings for fold toggling (za), opening (zo), closing (zc) etc all work as expected with vimish-fold.

Finally, also supports navigation between folds using zj and zk.

(use-package evil-vimish-fold
  :after (evil vimish-fold)
  :commands
  (evil-vimish-fold-mode)
  :config
  (evil-vimish-fold-mode 1)
  :hook
  (prog-mode . evil-vimish-fold-mode)
  (text-mode . evil-vimish-fold-mode)
  :diminish evil-vimish-fold-mode)

Commentary

Comments stuff out. A port of vim-commentary.

(use-package evil-commentary

 :demand t
 :commands
 (evil-commentary-mode
  evil-commentary-yank
  evil-commentary-line)
 :config (evil-commentary-mode)
 :diminish evil-commentary-mode)

Numbers

Increment / Decrement binary, octal, decimal and hex literals
Works like C-a~/~C-x in vim, i.e. searches for number up to eol and then increments or decrements and keep zero padding up (unlike in vim)
When a region is active, as in evil’s visual mode, all the numbers within that region will be incremented/decremented (unlike in vim)

(use-package evil-numbers
  :after (evil general)
  :demand t
  :config
  (nmap
    "C-c =" 'evil-numbers/inc-at-pt
    "C-c -" 'evil-numbers/dec-at-pt))

Bookmarks

Most of the keybindings are set by the evil-collection package.

(use-package bookmark
  :after general
  :init
  (setq
   bookmark-version-control t
   bookmark-save-flag 1)
  :config
  ;; Uncomment if you prefer going straight to bookmarks on Emacs startup.

Dired fl

Extra Emacs font lock rules for a more colourful dired. See the package repo for more info.

(use-package diredfl
 :after dired
 :hook
 (dired-mode . diredfl-mode))

Dired rsync

Adds a single command dired-rsync which allows the user to copy marked files in a dired buffer via rsync. This is useful, especially for large files, because the copy happens in the background and doesn’t lock up Emacs. It is also more efficient than using tramps own encoding methods for moving data between systems.

(use-package dired-rsync
 :config
 (nmap 'dired-mode-map
   "r" 'dired-rsync))

Dired launch

Launch an external application from dired.

(use-package dired-launch
 :hook

 :init
 ;; Use xdg-open as the default launcher
 (setq dired-launch-default-launcher '("xdg-open"))

Dired hacks.

Collection of useful dired additions.

Prerequisites

First, we need to install some dired hacks dependencies.

(use-package dash)
(use-package dired-hacks-utils
 :after dired

Filter

The filtering system is designed after ibuffer: every dired buffer has associated “filter stack” where user can push filters (predicates). These filters are by default logically “anded”, meaning, only the files satsifying all the predicates are shown.

(use-package dired-filter
 :after dired

Visually indent sections. This looks better for smaller files. Also, startup folded and disallow editing invisible areas.

(setq org-startup-indented t)
(setq org-startup-folded t)
(setq org-catch-invisible-edits 'error)

Show inline images when loading a new Org file.

(setq org-startup-with-inline-images t)

This feature came to Org in version 8. It lets you type “normal quotes” in the org buffer, as opposed to “this latex stuff”, and will transform them on export so that your HTML/text output looks nice and your latex export looks nice!

(setq org-export-with-smart-quotes t)

Forces to mark all child tasks as DONE before you can mark the parent as DONE.

(setq org-enforce-todo-dependencies t)

Allows displaying UTF-8 chars like \alpha.

(setq org-pretty-entities t)

Insert an annotation in a task when it is marked as done including a timestamp of when exactly that happened.

(setq org-log-done 'time)

Insert annotations when you change the deadline of a task, which will note the previous deadline date and when it was changed.

(setq org-log-redeadline (quote time))

Same as above, but for the scheduled dates.

(setq org-log-reschedule (quote time))

Hide leading stars.

(setq org-hide-leading-stars t)

Refile targets should include files and down to 9 levels into them.

(setq
 org-refile-targets
 (quote ((nil :maxlevel . 9)
  (org-agenda-files :maxlevel . 9))))

And inside those code blocks indentation should be correct depending on the source language used and have code highlighting.

(setq org-src-tab-acts-natively t)
(setq org-src-preserve-indentation t)
(setq org-src-fontify-natively t)

Set TODO priorities.

(setq

Compact the block agenda view.

(setq org-agenda-compact-blocks t)

Hide DONE items.

(setq
 org-agenda-skip-scheduled-if-done t
 org-agenda-skip-deadline-if-done t)

Set a 30 day span, instead of a week view.

(setq
 org-agenda-start-day "-3d"
 org-agenda-span 30)

Omit empty days in the agenda.

(setq org-agenda-show-all-dates nil)

Disable pre-warnings.

(setq org-deadline-warning-days 0)

Hide the time grid by default.

(setq org-agenda-use-time-grid nil)

Make the agenda schedule prettier.

(setq
 org-agenda-prefix-format

Makefile

Emacs helpers to run things from makefiles.

Interactively selecting a make target and running it. Bound to C-c C-e in makefile-mode when makefile-executor-mode is enabled.
Re-running the last execution. We usually run things in Makefiles many times after all! Bound to C-c C-c in makefile-mode when makefile-executor-mode is enabled.
Running a makefile target in a dedicated buffer. Useful when starting services and other long-running things! Bound to C-c C-d in makefile-mode when makefile-executor-mode is enabled.
Calculation of variables et.c.; $(BINARY) will show up as what it evaluates to.
If projectile is installed, execution from any buffer in a project. If more than one Makefile is found, an interactive prompt for one is shown. This is added to the projectile-commander on the m key.

Finalize

Set the frequency of garbage collections to big number (100mb) like most of the popular starter kits like Spacemacs/Doom/Prelude, etc do:

(setq gc-cons-threshold 100000000) ;; 100mb

Increase the amount of data which Emacs reads from the process. Again the emacs default is too low 4k considering that the some of the language server responses are in 800k - 3M range.

(setq read-process-output-max (* 1024 1024)) ;; 1mb
