dx f8ca6b9e1b +major refactors to vanilla Emacs config
Developed quite a bit of the config.

I've added a literate org config, loaded through the init.el file.
Furthermore, I've added some basic general maps and have gained a much
better understanding of Emacs than before. This refactor is one of the
main reasons I decided to so heavily refactor my doom config.

#+TITLE: Config for Emacs
#+AUTHOR: Oreodave
#+DESCRIPTION: My bespoke config for Emacs
#+PROPERTY: header-args :tangle yes
* 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
#+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.
#+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)
#+END_SRC
** Set some useful variables
Truncate lines, display number lines and stop making backup files (for now).
#+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)
#+END_SRC
* Keybindings
** Keychord
Setup key chord, pretty basic config.
#+BEGIN_SRC emacs-lisp
(use-package key-chord
:ensure t
:config
(key-chord-mode +1))
#+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.
#+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)
)
#+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)

#+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

(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=.
#+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
* Org-mode
** Vanilla org mode
#+BEGIN_SRC emacs-lisp
(use-package org
:ensure t
:config
(load (concat user-emacs-directory "+org.el"))
(nmap
:keymaps 'org-mode-map
"M-j" #'org-metadown
"M-k" #'org-metaup
"C-RET" #'dx:org-insert-item-below))
#+END_SRC
** Evil org mode
Setup evil org mode, which allows for some nicer abstractions of the interace.
#+BEGIN_SRC emacs-lisp
(use-package evil-org
:ensure t
:after org
:config
(add-hook 'org-mode-hook 'evil-org-mode)
(add-hook 'evil-org-mode-hook
(lambda ()
(evil-org-set-key-theme)))
(require 'evil-org-agenda)
(evil-org-agenda-set-keys))
#+END_SRC

#+BEGIN_SRC emacs-lisp
(use-package magit
:ensure t
:after general
:config
(gmap
"g" #'magit-status))
#+END_SRC
* Ace window
#+BEGIN_SRC emacs-lisp
(use-package ace-window

(setq aw-keys '(?a ?s ?d ?f ?g ?h ?j ?k ?l)
aw-dispatch-always t))
#+END_SRC

#+BEGIN_SRC emacs-lisp
(use-package counsel
