dot-emacs

NOTE: ⚠️ THIS CONFIG IS UNLIKELY TO HARM YOU/YOUR SYSTEM 🔥 Make Sure you backup your config before implementing this 🔥 ‼️

1 Intro

NOTE: init.el has been converted to README.org

This config was tested in Arch Linux and macOS Sierra(v 10.12.5)

1.1 Get it

$ git clone https://github.com/manishmarahatta/dot-emacs ~/.emacs.d/

1.2 How to build

configure 👷 , pulls down the el-get, and stuffs.

$ ./configure

Run and let the magic happen

OR

1.3 Script to automatically build emacs config(copy/paste and run the script)

#!/bin/sh

echo "=========================================="
echo "Wait, while the emacs config builds itself"
echo "=========================================="

cd ~

DIRFIRST=~/.emacs.d
DIRSECOND=~/.emacs.d.backup
FILEFIRST=~/.emacs

if [ ! -f $DIRFIRST ]
then
    mv ~/.emacs.d .emacs.d.backup;
fi

if [ ! -f $DIRSECOND ]
then
    mv ~/.emacs.d.backup .emacs.d.backup.another;
fi

if [ ! -f $FILEFIRST ]
then
    mv ~/.emacs .emacs.backup
fi

git clone https://github.com/manishmarahatta/dot-emacs.git ~/.emacs.d/
cd ~/.emacs.d
chmod +x configure
./configure
cd ~
emacs

save the above file as autoconfig.sh

chmod +x autoconfig.sh

Then type

./autoconfig.sh

2 emacs core

2.1 emacs garbage collector

(setq gc-cons-threshold 104857600)

2.2 emacs server

St opening emacs for each file. Set default open application using emacsclient -n -a=emacs [FILE].

(require 'server)
(unless (server-running-p)
  (server-start))

2.3 encoding

(setq locale-coding-system 'utf-8)
(set-language-environment 'utf-8)
(set-terminal-coding-system 'utf-8)
(set-keyboard-coding-system 'utf-8)
(set-selection-coding-system 'utf-8)
(prefer-coding-system 'utf-8)
(when (display-graphic-p)
   (setq x-select-request-type '(UTF8_STRING COMPOUND_TEXT TEXT STRING)))

2.4 backup configuration

(setq backup-directory-alist (quote ((".*" . "~/.cache/emacs_backup/"))))
(setq make-backup-files nil)

2.5 alias ‘yes’ and ‘no

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

2.6 recent files

;; (recentf-mode nil)

3 el-get

el-get is the package manager, which is similar to apt-get.

(add-to-list 'load-path "~/.emacs.d/el-get")
(require 'el-get)
(setq el-get-git-shallow-clone 't)
(el-get 'sync)

3.1 my packages

To replicate a package set for another emacs installation is explain in el-get README. you can list current installed package using.

`(setq my-packages
    ',(mapcar #'el-get-as-symbol
          (el-get-list-package-names-with-status "installed")))

this is the same of current packages which are installed.

PS: it’s osx compatibile “chill”

   (setq dim-packages
          (append
   ;; list of packages we use straight from official recipes
             '(ample-regexps auto-complete cl-lib ctable dash
             deferred ein epc epl exec-path-from-shell f flymake
             flymake-cursor fuzzy git-modes goto-chg jedi json-mode
			   json-reformat json-snatcher magit go-eldoc go-autocomplete multiple-cursors
			   pkg-info popup popup-kill-ring pos-tip pylookup python
			   python-environment recentf-ext request s undo-tree
			   web-mode websocket go-mode yasnippet ac-helm outorg package)
			 (mapcar 'el-get-as-symbol (mapcar 'el-get-source-name
			 el-get-sources))))
	 (el-get 'sync dim-packages)

4 UI/UX

Basic configuration, like window size keybindings

	(load "~/.emacs.d/config/ui.cfg.el")

these are kind of strange bindings for beginner and for me too, so lets remove it

	(global-unset-key [(control prior)])
	(global-unset-key [(control next)])

I find these binding quite handful.

	(el-get 'sync 'fill-column-indicator)
	(require 'fill-column-indicator)
	(global-set-key [M-f4] 'save-buffers-kill-terminal)
	(global-set-key [(control f5)] '(lambda() (interactive)
									(load-file "~/.emacs.d/init.el")))
	(global-set-key [f6] '(lambda() (interactive)
						  (toggle-truncate-lines)
						  (fci-mode)))
	(global-set-key [f9] 'speedbar)

4.1 shift mouse selection

We don’t need font dialog options which is binded by default. Since, font resize has been binded to C mouse scroll does it.

	 (global-unset-key [(shift down-mouse-1)])
	 (global-set-key [(shift down-mouse-1)] 'mouse-save-then-kill)

4.2 highlight current line

Uses shade-color defined in config/ui.cfg.el to compute new intensity of given color and alpha value.

	 (el-get 'sync 'highline)
	 (require 'highline)

	 (set-face-background 'highline-face (shade-color 09))
	 (add-hook 'prog-mode-hook 'highline-mode-on)

	 ;; not using inbuild hl-line-mode i can't seem to figure out changing
	 ;; face for shade-color
	 ;; (global-hl-line-mode 1)
	 ;; (set-face-background 'hl-line "#3e4446")
	 ;; (set-face-foreground 'highlight nil)
	 ;; (set-face-attribute hl-line-face nil :underline nil)

4.3 custom undo action for GUI

	 (when window-system
	   (require 'undo-tree)
	   (global-undo-tree-mode 1)
	   (global-unset-key (kbd "C-/"))
	   (defalias 'redo 'undo-tree-redo)
	   (global-unset-key (kbd "C-z"))
	   (global-set-key (kbd "C-z") 'undo-only)
	   (global-set-key (kbd "C-S-z") 'redo))

4.4 modeline

	 ;;; mode-icons directly from repo, for experiments
	 ;;; https://github.com/ryuslash/mode-icons
	 (load-file "~/.emacs.d/modules/mode-icons/mode-icons.el")
	 ;;; DID YOU GOT STUCK ABOVE? COMMENT LINE ABOVE & UNCOMMENT NEXT 2 LINES
	 ;; (el-get 'sync 'mode-icons)
	 ;; (require 'mode-icons)
	 ;; (setq mode-icons-desaturate-inactive nil)
	 ;; (setq mode-icons-desaturate-active nil)
	 ;; (setq mode-icons-grayscale-transform nil)
	 (mode-icons-mode)

	 (el-get 'sync 'powerline)
	 (require 'powerline)

	 ;;; https://github.com/manishmarahatta/powerline-iconic-theme
	 ;; (add-to-list 'load-path "~/.emacs.d/modules/powerline-iconic-theme/")
	 (load-file "~/.emacs.d/modules/powerline-iconic-theme/iconic.el")
	 (powerline-iconic-theme)
	 ;;; DID YOU GOT STUCK ABOVE? COMMENT 2 LINES ABOVE & UNCOMMENT NEXT LINE
	 ;;(powerline-default-theme)

	 ;;; modeline from spacmacs
	 ;;; https://github.com/TheBB/spaceline
	 ;; (add-to-list 'load-path	 "~/.emacs.d/modules/spaceline/")
	 ;; (require 'spaceline-config)
	 ;; (spaceline-spacemacs-theme)

4.5 tabbar

	 (el-get 'sync 'tabbar)
	 (require 'tabbar)
	 (tabbar-mode t)


	 ;;; tabbar-ruler directly from repo, for experiments
	 ;;; https://github.com/mattfidler/tabbar-ruler.el
	 (load-file "~/.emacs.d/modules/tabbar-ruler/tabbar-ruler.el")
	 ;;; DID YOU GOT STUCK ABOVE? COMMENT LINE ABOVE & UNCOMMENT NEXT 2
	 ;; (el-get 'sync 'tabbar-ruler)
	 ;; (require 'tabbar-ruler)

	 (setq tabbar-ruler-style 'firefox)

	 (load "~/.emacs.d/config/tabbar.cfg.el")
	 (global-set-key [f7] 'tabbar-mode)

bind them as modern GUI system.

	 (define-key global-map [(control tab)] 'tabbar-forward)
	 (define-key global-map [(control next)] 'tabbar-forward)
	 (define-key global-map [(control prior)] 'tabbar-backward)
	 (define-key global-map (kbd "C-S-<iso-lefttab>") 'tabbar-backward)

Binding for the tab groups, some how I use lots of buffers.

	 (global-set-key [(control shift prior)] 'tabbar-backward-group)
	 (global-set-key [(control shift next)] 'tabbar-forward-group)

4.6 smooth scroll

Unfortunately emacs 💈 scrolling 💈 is not smooth, its 2017 already.

	  (el-get 'sync 'smooth-scroll)
	  (require 'smooth-scroll)
	  (smooth-scroll-mode t)

	  (setq linum-delay t)
	  (setq redisplay-dont-pause t)

	  (setq auto-window-vscroll nil)

	  (setq mouse-wheel-progressive-speed 10)
	  (setq mouse-wheel-follow-mouse 't)

	   (global-set-key (kbd "C-x C-f") 'helm-find-files)
	   (helm-mode 1)

4.10 anzu

Highlight all search matches, most of the text editor does this why not emacs. Here is the gify from original repo.

	 (el-get 'sync 'anzu)
	 (require 'anzu)
	 (global-anzu-mode +1)
	 (global-unset-key (kbd "M-%"))

	   (global-set-key (kbd "C-S-<mouse-1>") 'mc/add-cursor-on-click))

4.12 goto-last-change

This is the gem feature, this might be true answer to the sublime mini-map which is over rated, this is what you need.

If you aren’t using el-get here is the source, guessing it its avaliable in all major repository by now.

	 (el-get 'sync 'goto-chg)
	 (require 'goto-chg)
	 (global-unset-key (kbd "C-j"))
