+brand new Emacs config

Browse Source 
This one is a lot more closer to Emacs core, it doesn't use general
or the SPC leader as I'm used to but instead the default meta-key
chord bindings to work better. I don't use a lot of features in Emacs
that Doom used to provide in bindings, so I'm stripping them away and
slowly adding stuff I like.

#+TITLE: Config for Emacs
#+TITLE: Emacs configuration
#+AUTHOR: Oreodave
#+DESCRIPTION: My bespoke config for Emacs
#+PROPERTY: header-args :tangle yes
#+DESCRIPTION: My new Emacs configuration
* Notes
This setup uses emacs 27, with use-package and melpa.
Code structure is pretty simple:
- parent packages or packages that other packages leverage greatly are configured first.
I use =:after= as a depdence generator: in most circumstances.
* Init
** Set some details
Some basic details set for the purposes of Emacs
#+BEGIN_SRC emacs-lisp
(setq user-emacs-directory (expand-file-name "~/.config/emacs/")
ring-bell-function 'ignore
inhibit-startup-screen t)
#+END_SRC
** Turn off those annoying bars
Annoying menu bars, tool bars, etc
* Initial
** Setup straight
Bootstrap of straight (from github)
#+BEGIN_SRC emacs-lisp
(defvar bootstrap-version)
(let ((bootstrap-file
(expand-file-name "straight/repos/straight.el/bootstrap.el" user-emacs-directory))
(bootstrap-version 5))
(unless (file-exists-p bootstrap-file)
(with-current-buffer
(url-retrieve-synchronously
"https://raw.githubusercontent.com/raxod502/straight.el/develop/install.el"
'silent 'inhibit-cookies)
(goto-char (point-max))
(eval-print-last-sexp)))
(load bootstrap-file nil 'nomessage))
#+END_SRC
** Setup use package
Straight clone use-package and state that all use-package statements implicity use straight.
#+BEGIN_SRC emacs-lisp
(straight-use-package 'use-package)
(setq straight-use-package-by-default t)
#+END_SRC
** Setup alpha and yes-or-no-p
This just sets the alpha to 85% and all yes or no questions to single letter responses.
#+BEGIN_SRC emacs-lisp
(add-to-list 'default-frame-alist '(alpha . 85))
(fset 'yes-or-no-p 'y-or-n-p)
#+END_SRC
** Hs Minor mode
Turn on hs minor mode for all prog-mode.
#+BEGIN_SRC emacs-lisp
(add-hook 'prog-mode-hook #'hs-minor-mode)
#+END_SRC
** Set backup directory
Set the backup directory to =user-emacs-directory=/saves so I don't get those annoying '~' files.
#+BEGIN_SRC emacs-lisp
(setq backup-directory-alist `(("." . "~/.config/emacs/saves")))
#+END_SRC
** Turn off the bars
Turn off all the bars, don't need them anymore!
#+BEGIN_SRC emacs-lisp
(tool-bar-mode -1)
(scroll-bar-mode -1)
(tab-bar-mode -1)
(menu-bar-mode -1)
#+END_SRC
** Set fonts and alpha
Make two constants that hold the values for font and alpha, then set them in Emacs.
** Themes
Load my custom "Grayscale" theme (look at [[file:Grayscale-theme.el][this file]]).
#+BEGIN_SRC emacs-lisp
(defconst dx:font "IBM Plex Mono-12" "Default font for Emacs")
(defconst dx:alpha 0.9 "Default alpha transparency for Emacs")
(add-to-list 'default-frame-alist (cons 'font dx:font))
(add-to-list 'default-frame-alist (cons 'alpha dx:alpha))
(set-face-attribute 'default t :font dx:font)
(add-hook 'prog-mode-hook #'hs-minor-mode)
(add-hook 'prog-mode-hook #'display-line-numbers-mode)
(load-theme 'Grayscale t)
#+END_SRC
** Set some useful variables
Truncate lines, display number lines and stop making backup files (for now).
* Emacs Mode-line
Firstly, declare a variable for the number of spaces between each module in the modeline.
#+BEGIN_SRC emacs-lisp
(defconst +modeline/sep-spaces 4 "Number of spaces separating modules.")
#+END_SRC
Then, declare a list of reserved characters for which the previously declared seperator won't be applied when placed at the end of a module string.
#+BEGIN_SRC emacs-lisp
(defconst +modeline/reserved-chars (list "[" "(")
"Characters that, when at the end of a module string, won't have the separator applied to them.")
#+END_SRC
Now declare a function that applies the separator with respect to the reserved characters to any one string.
#+BEGIN_SRC emacs-lisp
(defun +modeline/handle-string (STR)
(condition-case nil
(progn
(string-blank-p STR)
(cond ((cl-member (car (last (split-string STR "" t))) +modeline/reserved-chars :test #'string=) STR)
(t (concat STR (cl-reduce #'concat (cl-loop for i from 1 to +modeline/sep-spaces collect " "))))))
(error STR)))
#+END_SRC
Finally, set the mode-line-format.
#+BEGIN_SRC emacs-lisp
(setq-default
mode-line-format
(mapcar #'+modeline/handle-string
(list "%l:%c"
"%p["
'(:eval (upcase
(substring
(format "%s" (if (bound-and-true-p evil-state) evil-state ""))
0 1)))
"]"
"%+%b("
'(:eval (format "%s" major-mode))
")"
"%I"
vc-mode
mode-line-end-spaces)))
#+END_SRC
* Custom Functions
These are custom functions I have defined
** New line function
Vim bindings don't have a nice way of adding new lines before or after the current line while staying in normal mode.
You can use =o/O= to enter insert mode at a new line, but this isn't the same as being able to stay in normal mode, and only adds extra keypresses if your only purpose was to open up some lines.
As this is Emacs I can extend it as I wish, so I decided to define a new line function that won't remove me from normal state.
The logic is pretty simple:
- Use the predefined vim functions for opening new lines above and below with insert mode
- Given the argument =BACKWARD= to assess whether to open lines above or below
- Return to previous location
- Enter normal state
#+BEGIN_SRC emacs-lisp
(setq completion-ignore-case t
truncate-lines t
display-line-numbers-type t
make-backup-files nil)
#+END_SRC
** ido mode
Setup ido mode, easy to use completion framework.
#+BEGIN_SRC emacs-lisp
(ido-mode +1)
(with-eval-after-load "evil"
(defun dx:newline (&optional BACKWARD)
(interactive)
(let ((old (point)))
(cond ((and BACKWARD (= BACKWARD 1)) (evil-open-below 1))
(t (evil-open-above 1)))
(goto-char (+ old 1))
(evil-normal-state))))
#+END_SRC
** Generate tags
For some reason, I can't seem to rely on the =projectile-regenerate-tags= function, so define my own.
Steps are as follows:
- Consider the =root= to be either =default-directory= or the =projectile-project-root= depending on if it's loaded and set.
- Start a process (shell command) by changing to =root= and executing =ctags -Re=
#+BEGIN_SRC emacs-lisp
(defun dx:generate-tags ()
(interactive)
(let ((root (if (bound-and-true-p projectile-project-root)
projectile-project-root
default-directory)))
(start-process-shell-command "" nil (format "cd %s; ctags -Re ." root))))
#+END_SRC
* Keybindings
** Keychord
Setup key chord, pretty basic config.
** Global map
Any functions that are already loaded, set them to the global map.
#+BEGIN_SRC emacs-lisp
(use-package key-chord
:ensure t
:config
(key-chord-mode +1))
(bind-keys
:map global-map
("<menu>" . nil)
("M-v" . (lambda () (interactive) (dx:newline 1)))
("M-V" . (lambda () (interactive) (dx:newline)))
("C-c !" . async-shell-command)
("C-c c" . compile)
("M-s i" . imenu)
("M-n f" . narrow-to-defun)
("M-n w" . widen)
("M-n r" . narrow-to-region))
#+END_SRC
** General
Setup for general, keybinding library.
I use the function =general-evil-setup= to use the =*map= family of keymapping functions.
In this case I setup two defines: =gmap= and =lmap=.
=gmap= is for all global maps while lmap is for local, mode based keybindings
I also have a good bit of bindings setup here, such that any default emacs functions that I use regularly is setup here.
** Menu map
Any keys I want to map to <menu>, the weird little menu interaction button on some keyboards.
#+BEGIN_SRC emacs-lisp
(use-package general
:ensure t
:init
;; Definers
(general-def :states 'normal
"SPC" nil)
(general-create-definer gmap :prefix "SPC")
(general-create-definer lmap :prefix "SPC m")
(general-evil-setup t)
)
(bind-keys
:prefix "<menu>"
:prefix-map dx:menu-map
("<menu>" . execute-extended-command)
("p" . (lambda () (interactive) (find-file (concat user-emacs-directory "config.org"))))
("#" . (lambda () (interactive) (projectile-find-file)))
("/" . counsel-rg)
("." . imenu))
#+END_SRC
* Which key
#+BEGIN_SRC emacs-lisp
(use-package which-key
:ensure t
:config
(which-key-mode +1))
#+END_SRC
* Evil
Basic evil configuration with some keychords.
#+BEGIN_SRC emacs-lisp
(use-package evil
:ensure t
:after key-chord general
:config
(evil-mode +1)
(key-chord-define evil-insert-state-map "jk" #'evil-normal-state)
;; Keybindgs
(gmap "SPC" #'execute-extended-command)
;; Files
(gmap
:infix "f"
"f" #'find-file
"p" #'(lambda () (interactive) (find-file "~/.config/emacs/init.el"))

"i" #'ibuffer)
;; Other
(gmap
"c" #'compile)
(vmap
:keymaps 'emacs-lisp-mode-map
"gr" #'eval-region)
)
#+END_SRC
** Evil default
Setup the evil package, with some basic keybinds.
#+BEGIN_SRC emacs-lisp
(use-package evil
:init
(setq evil-want-keybinding nil)
:config
(evil-mode +1)
(bind-key "TAB" #'evil-jump-item evil-normal-state-map)
(evil-define-key 'visual 'emacs-lisp-mode-map "gr" #'eval-region))
#+END_SRC
** Evil surround
#+BEGIN_SRC emacs-lisp
(use-package evil-surround
:ensure t
:after evil
:config
(global-evil-surround-mode +1))
#+END_SRC
* Helpful
#+BEGIN_SRC emacs-lisp
(use-package evil-surround
:after evil
:config
(global-evil-surround-mode))
#+END_SRC
** Evil commentary
#+BEGIN_SRC emacs-lisp
(use-package evil-commentary
:after evil
:config
(evil-commentary-mode))
#+END_SRC
** Evil mc
Setup for multicursors in Evil mode.
Don't let evil-mc setup it's own keymap because it uses 'gr' as its prefix, which I don't like.
Instead, bind some useful functions to my personal =dx:evil-mc-map= which is bound to 'gz'.
Furthermore, define a function =dx:evil-mc-cursor-here= which pauses cursors upon placing a cursor at the current position.
#+BEGIN_SRC emacs-lisp
(use-package evil-mc
:after evil
:bind (("M-p" . evil-mc-skip-and-goto-prev-cursor)
:map dx:evil-mc-map
("q" . evil-mc-undo-all-cursors)
("d" . evil-mc-make-and-goto-next-match)
("j" . evil-mc-make-cursor-move-next-line)
("k" . evil-mc-make-cursor-move-prev-line)
("j" . evil-mc-make-cursor-move-next-line)
("m" . evil-mc-make-all-cursors)
("z" . dx:evil-mc-cursor-here)
("r" . evil-mc-resume-cursors)
("s" . evil-mc-pause-cursors))
:init
(defvar evil-mc-key-map (make-sparse-keymap))
(define-prefix-command 'dx:evil-mc-map)
(bind-key "gz" dx:evil-mc-map evil-normal-state-map)
(bind-key "gz" dx:evil-mc-map evil-visual-state-map)
:config
(global-evil-mc-mode +1)
(defun dx:evil-mc-cursor-here ()
(interactive)
(evil-mc-make-cursor-here)
(evil-mc-pause-cursors)))
#+END_SRC
** Evil collection
Setup evil collection, but don't turn on the mode.
Instead, I'll turn on setups for specific modes I think benefit from it.
#+BEGIN_SRC emacs-lisp
(use-package evil-collection
:after evil)
#+END_SRC
* IBuffer
#+BEGIN_SRC emacs-lisp
(use-package helpful
:after general
:ensure t
:config
(gmap
:infix "h"
"f" #'helpful-callable
"v" #'helpful-variable
"k" #'helpful-key))
(use-package ibuffer
:bind ("<menu> ," . ibuffer)
:after evil-collection
:config
(evil-collection-ibuffer-setup))
#+END_SRC
* Yasnippet
#+BEGIN_SRC emacs-lisp
(use-package yasnippet
:ensure t
:after general
:config
(add-hook 'prog-mode-hook #'yas-minor-mode)
(gmap
"is" #'yas-insert-snippet))
(use-package yasnippet-snippets
:ensure t
:after yasnippet)
#+END_SRC
* Doom-themes
Setup for doom themes.
Allow bold themes but not italic (italic is harder to read).
Allow doom themes to configure org mode to fix fonts on headers, etc.
Define a function that does the same thing as =counsel-load-function-action= without the dependency on counsel.
Load a theme using said function, in this case =doom-monokai-classic=.
* Dired
Setup for dired.
Firstly, as it's an inbuilt package don't let straight try and download it.
Make dired-hide-details-mode the default mode when dired-mode, as it removes the clutter.
Create a keymap =dx:dired-map= which is bound to the prefix "C-c d", binding useful dired functions.
Setup evil collection for dired (even though dired doesn't really conflict with evil, there are some black corners I'd like to adjust)
#+BEGIN_SRC emacs-lisp
(use-package doom-themes
:ensure t
:config
(setq doom-themes-enable-bold t
doom-themes-enable-italic nil)
(doom-themes-org-config)
(defun dx:load-theme (theme)
"Load a given theme into Emacs, while unloading the rest"
(mapc #'disable-theme custom-enabled-themes)
(load-theme theme t))
(dx:load-theme 'doom-monokai-classic))
#+END_SRC
(use-package dired
:straight nil
:hook (dired-mode . dired-hide-details-mode)
:bind-keymap* ("C-c d" . dx:dired-map)
:after evil-collection
:init
(defvar dx:dired-map (make-sparse-keymap) "dx:dired-map")
:config
(bind-keys
:map dx:dired-map
("f" . find-dired)
("D" . dired-other-window)
("d" . dired-jump))
(evil-collection-dired-setup))
#+END_SRC
* Helpful
Basic setup, will be fully integrated in counsel.
#+BEGIN_SRC emacs-lisp
(use-package helpful
:commands (helpful-callable helpful-variable))
#+END_SRC
* Which-key
Pretty simple, just activate after init.
#+BEGIN_SRC emacs-lisp
(use-package which-key
:hook (after-init . which-key-mode))
#+END_SRC
* Avy
Avy is an incredibly useful package that I have just started to understand.
For now, I have two bindings for =avy-goto-line= and =avy-goto-char-2= as I use them often.
#+BEGIN_SRC emacs-lisp
(use-package avy
:bind (("M-g" . #'avy-goto-char-2)
("M-l" . #'avy-goto-line)))
#+END_SRC
* Hydra
I haven't found a use for it yet, so don't tangle this.
#+BEGIN_SRC emacs-lisp :tangle no
(use-package hydra)
#+END_SRC
* Yasnippet
Yasnippet is a great package for snippets, which I use heavily in programming and org-mode.
I setup here the global mode for yasnippet and a collection of snippets for ease of use.
** Yasnippet default
Setup global mode after evil mode has been loaded
#+BEGIN_SRC emacs-lisp
(use-package yasnippet
:after evil
:hook (after-init . yas-global-mode)
:bind ("C-c i" . yas-insert-snippet))
#+END_SRC
** Yasnippet snippets
Collection of snippets, activate after yasnippet has been loaded.
#+BEGIN_SRC emacs-lisp
(use-package yasnippet-snippets
:after yasnippet)
#+END_SRC
* Keychord
Keychord is only really here for this one chord I wish to define: "jk" for exiting insert state.
Otherwise, I don't really need it.
#+BEGIN_SRC emacs-lisp
(use-package key-chord
:after evil
:config
(key-chord-define evil-insert-state-map "jk" #'evil-normal-state)
(key-chord-mode +1))
#+END_SRC
* Ivy
Ivy is a completion framework for Emacs, and my preferred (sometimes second favourite) one.
It has a great set of features with little to no pain with setting up.
** Ivy
Setup for ivy, in preparation for counsel.
Turn on ivy-mode just after init.
Setup vim-like bindings for the minibuffer ("C-(j|k)" for down|up the selection list)
Also setup evil-collection for ivy.
#+BEGIN_SRC emacs-lisp
(use-package ivy
:after evil-collection
:hook (after-init . ivy-mode)
:bind (:map ivy-minibuffer-map
("C-j" . ivy-next-line-or-history)
("C-k" . ivy-previous-line-or-history)
:map ivy-switch-buffer-map
("C-j" . ivy-next-line-or-history)
("C-k" . ivy-previous-line-or-history))
:config
(evil-collection-ivy-setup))
* Org-mode
** Vanilla org mode
#+END_SRC
** Counsel
Setup for counsel.
Load after ivy and helpful.
Bind:
- Swiper to "C-s"
- Switch buffer to "C-x b"
- Counsel ripgrep to "M-s r" (search namespace)
Along with that, set the help function and variable functions to their helpful counterparts.
#+BEGIN_SRC emacs-lisp
(use-package counsel
:after (ivy helpful)
:bind (("C-s" . counsel-grep-or-swiper)
("C-x b" . counsel-switch-buffer)
("M-s r" . counsel-rg))
:config
(setq ivy-initial-inputs-alist nil
counsel-describe-function-function #'helpful-callable
counsel-describe-variable-function #'helpful-variable))
#+END_SRC
** Counsel etags
Counsel etags allows me to search generated tag files for tags.
I already have a function defined [[*Generate tags][here]] to generate the tags, so it's just searching them which I find to be a bit of a hassle, and where this package comes in.
#+BEGIN_SRC emacs-lisp
(use-package counsel-etags
:after counsel
:bind ("M-s t" . counsel-etags-find-tag))
#+END_SRC
* Projectile
** Projectile default
Setup projectile, along with the tags command.
Also bind "C-c C-p" to the projectile command map for quick access.
#+BEGIN_SRC emacs-lisp
(use-package projectile
:after evil
:hook (prog-mode . projectile-mode)
:bind-keymap* ("C-c C-p" . projectile-command-map)
:init
(setq projectile-tags-command "ctags -Re -f \"%s\" %s \"%s\"")
:config
(projectile-global-mode))
#+END_SRC
** Counsel projectile
Counsel projectile provides the ivy interface to projectile commands, which is really useful.
#+BEGIN_SRC emacs-lisp
(use-package counsel-projectile
:after (projectile counsel)
:config
(counsel-projectile-mode +1))
#+END_SRC
* Magit
Magit is *the* git porcelain for Emacs, which perfectly encapsulates the git cli.
In this case, I just need to setup the bindings for it.
As magit will definitely load after evil (as it must be run by a binding, and evil will load after init), I can use evil-collection freely.
#+BEGIN_SRC emacs-lisp
(use-package magit
:bind (("C-x g g" . magit-status)
("C-x g c" . magit-clone)
("C-x g l" . magit-log)))
(use-package evil-magit
:after magit)
#+END_SRC
* Company
Company is the auto complete system I use.
I don't like having heavy setups for company, as it only makes it worse to use.
In this case, just setup some evil binds for company
#+BEGIN_SRC emacs-lisp
(use-package company
:hook (prog-mode . company-mode)
:bind (("C-SPC" . company-complete)
:map company-active-map
("C-j" . company-select-next)
("C-k" . company-select-previous)))
#+END_SRC
* Elfeed
Elfeed is the perfect RSS feed reader, integrated into Emacs perfectly.
I've got a set of feeds that I use for a large variety of stuff, mostly media and entertainment.
I've also bound "C-c r" to elfeed for loading the system.
#+BEGIN_SRC emacs-lisp

* Major modes and Programming
Setups for common major modes and languages
Here are some basic packages for programming first
** Smartparens
Smartparens is a smarter electric-parens, it's much more aware of stuff and easier to use.
#+BEGIN_SRC emacs-lisp
(use-package smartparens
:after evil
:config
(setq sp-highlight-pair-overlay nil
sp-highlight-wrap-overlay t

#+END_SRC
** Show-paren-mode
Show parenthesis for Emacs
#+BEGIN_SRC emacs-lisp
(add-hook 'prog-mode-hook #'show-paren-mode)
#+END_SRC
** Eglot
Eglot is a library of packages to communicate with LSP servers for better programming capabilities.
Interactions with a server provide results to the client, done through JSON.
#+BEGIN_SRC emacs-lisp
(use-package eglot
:hook (c++-mode . eglot-ensure)
:hook (c-mode . eglot-ensure)
:bind (:map eglot-mode-map
("<f2>" . eglot-rename)
("C-c C-A" . eglot-code-actions)
("C-c f" . eglot-format))
:config
(add-to-list 'eglot-server-programs '((c-mode c++-mode) "clangd")))
#+END_SRC
** Flycheck
Flycheck is the checking system for Emacs.
I don't necessarily like having all my code checked all the time, so I haven't added a hook to prog-mode as it would be better for me to decide when I want checking and when I don't.
#+BEGIN_SRC emacs-lisp
(use-package flycheck
:commands flycheck-mode
:bind ("C-c x" . flycheck-list-errors))
#+END_SRC
** Activate tabs
Set tabs to nil by default, with normal tab size set to 2.
#+BEGIN_SRC emacs-lisp
(setq-default indent-tabs-mode nil
tab-width 2)
#+END_SRC
Add a function to activate tabs mode.
#+BEGIN_SRC emacs-lisp
(defun dx:activate-tabs ()

(setq indent-tabs-mode t))
#+END_SRC
** C/C++
*** C Offset
#+BEGIN_SRC emacs-lisp
(setq-default c-basic-offset 2)
#+END_SRC
*** Clang format
use-package clang-format for ease of use formatting, binding to "C-c '" for both C and C++ mode maps.
#+BEGIN_SRC emacs-lisp

*** Tabs mode for C and C++
Add tabs to both C and C++ modes via =activate-tabs= function.
#+BEGIN_SRC emacs-lisp
(add-hook 'c-mode-hook #'dx:activate-tabs)
(add-hook 'c++-mode-hook #'dx:activate-tabs)
#+END_SRC
*** Custom user style
Add a custom style which follows something like a 'Microsoft Style' in that it opens braces everywhere (for ease of reading).
