#+TITLE: Oreodave's Emacs configuration
#+AUTHOR: Oreodave
#+DESCRIPTION: My Doom Emacs configuration!

* Preclude
- This is my [[https://github.com/hlissner/doom-emacs][Doom Emacs]] configuration.
- Use it for most of my code editing and development needs.
- Incredibly versatile tool in my inventory.
* Initial setup
** Doom Variables
- Set the doom localleader to "," because it's faster
- Using the font [[https://sourcefoundry.org/hack/][Hack]]
#+BEGIN_SRC elisp
(after! core-keybinds
  (map! :leader "," nil)
  (setq doom-localleader-key "SPC ,")
  (setq doom-theme 'doom-gruvbox)
  (setq doom-font (font-spec :family "Hack" :size 15)))
#+END_SRC
** Other variables
Some quality of life things and others that I couldn't really put in one category
- Using line-numbers that are relative now instead of nothing.
- Set org directory
- Add libgen to search providers
#+BEGIN_SRC elisp
(setq completion-ignore-case t)
(setq truncate-lines t)
(setq display-line-numbers-type t)
(setq bookmark-default-file (expand-file-name (concat doom-private-dir "bookmarks")))
(setq-default frame-title-format '("%b - Emacs"))
(add-to-list 'default-frame-alist '(alpha . 95))
(cl-pushnew '("Libgen" "http://gen.lib.rus.ec/search.php?req=%s") +lookup-provider-url-alist :key #'car :test 'string=)
#+END_SRC
** HACK: Loading org mode
For some reason, currently, the org mode keybinds aren't working.
So reload the file again until the issue is fixed.
#+BEGIN_SRC elisp
(load "~/.emacs.d/modules/lang/org/config.el")
#+END_SRC
* Package Config
Config for or based heavily around specific packages that I find very important
** DAP
*** Function
First to setup is a routine for setting up all the dap-panes for debugging.
Easier to do than just running all those functions manually
- Routine sets up the panes that I like to use, instead of M-x'ing it
- *<SPC>cD* starts up the routine
#+BEGIN_SRC elisp
(after! dap-mode
  (defun dx:debug ()
    (interactive)
    (dap-ui-mode)
    (dap-ui-locals)
    (dap-ui-sessions)))
#+END_SRC
*** Keybind
#+BEGIN_SRC elisp
(map!
 :after dap-mode
 :leader
 :desc "Start debugging setup" "cD" #'dx:debug)
#+END_SRC
** Dashboard
My very own dashboard config using doom dashboard, with these features:
- Custom load message
- Custom splash image and dashboard buffer name
- Custom dashboard sections for myself

*** Benchmark display
Redo the display-benchmark function to display a different message
#+BEGIN_SRC elisp
(defun doom-display-benchmark-h (&optional return-p)
  "Display a benchmark, showing number of packages and modules, and how quickly
they were loaded at startup.

If RETURN-P, return the message as a string instead of displaying it."
  (funcall (if return-p #'format #'message)
           "εmacs loaded %d packages, %d modules in %.03fs"
           (- (length load-path) (length doom--initial-load-path))
           (if doom-modules (hash-table-count doom-modules) 0)
           (or doom-init-time
               (setq doom-init-time
                     (float-time (time-subtract (current-time) before-init-time))))))
#+END_SRC

*** Image and buffer name
Set the splash-image and dashboard buffer name
Space image comes from [[https://flaticon.com][website]]
#+BEGIN_SRC elisp
(setq fancy-splash-image "~/Pictures/SplashScreens/space2.png") ; splash image
(setq +doom-dashboard-name "*dashboard*")
#+END_SRC
*** Dashboard items
Set the dashboard functions (segments in overall buffer), set the sections of the interactive menu as well.
#+BEGIN_SRC elisp
(setq +doom-dashboard-functions ; limit the dashboard items
      '(doom-dashboard-widget-banner
        doom-dashboard-widget-loaded
        doom-dashboard-widget-shortmenu))

(setq +doom-dashboard-menu-sections ; Set a specific amount of items
      '(("Open org-agenda"
         :icon (all-the-icons-octicon "calendar" :face 'font-lock-keyword-face)
         :when (fboundp 'org-agenda)
         :action org-agenda)
        ("Jump to bookmark"
         :icon (all-the-icons-octicon "bookmark" :face 'font-lock-keyword-face)
         :action bookmark-jump)
        ("Open project"
         :icon (all-the-icons-material "folder" :face 'font-lock-keyword-face)
         :action projectile-switch-project)))
#+END_SRC
** Spelling checker
Keybinds to org-mode for flyspell package
#+BEGIN_SRC elisp
(map!
 :after (flyspell org)
 :localleader
 :map org-mode-map
 :prefix "w"
 :desc "Correct current word" "c" #'flyspell-correct-at-point
 :desc "Autocorrect word"     "a" #'flyspell-auto-correct-word
 :desc "Goto next error"      "w" #'flyspell-goto-next-error)
#+END_SRC
** Projectile
Add CMakeLists.txt to projectile-project-roots.
#+BEGIN_SRC elisp
(after! projectile
  (cl-pushnew "CMakeLists.txt" projectile-project-root-files :test 'string=)
  (setq projectile-tags-command
        "ctags -e -R --exclude=dist --exclude=.ccls --exclude=.ccls-cache"))
#+END_SRC
** Prettify symbols
Configuration for the module (pretty-code).
*** Setup symbols
Some symbols aren't present in the current doom version, or my fonts are screwing up, so I wrote them here.
Maybe a bit of a bandage over broken glass, but at least it's something.
#+BEGIN_SRC elisp
(setq +pretty-code-symbols
      '(:name "»"
        :src_block "»"
        :src_block_end "«"
        :quote "“"
        :quote_end "”"
        :lambda "λ"
        :def "ƒ"
        :composition "∘"
        :map "↦"
        :null "∅"
        :true "𝕋"
        :false "𝔽"
        :int "ℤ"
        :float "ℝ"
        :str "𝕊"
        :bool "𝔹"
        :not "¬"
        :in "∈"
        :not-in "∉"
        :and "∧"
        :or "∨"
        :for "∀"
        :some "∃"
        :return "⟼"
        :yield "⟻"
        :tuple "⨂"
        :pipe "|"
        :dot "•"))
#+END_SRC

The 'x' symbol in the =+pretty-code-fira-code-font-ligatures= is annoying, and unneeded.
So I remove it.
#+BEGIN_SRC elisp
(assoc-delete-all "x" +pretty-code-fira-code-font-ligatures #'string=)
#+END_SRC
*** Pretty symbols
Setup pretty symbols specifically for C++.
I import the string type via `using std::string` which isn't supported in standard doom so I added support for it as well.
#+BEGIN_SRC elisp
(after! cc-mode
  (set-pretty-symbols!
    '(c-mode c++-mode)
    :return "return"
    :or "||"
    :and "&&"
    :not "!"
    :bool "bool"
    :str "string"
    :str "std::string"
    :float "float"
    :int "int"
    :false "false"
    :true "true"
    :null "nullptr"))
#+END_SRC
** Calc
*** Configuration
#+BEGIN_SRC elisp
(use-package! calc
  :config
  (setq calc-angle-mode 'rad)
  (map!
   :leader
   :desc "Calc" ":" #'calc))
#+END_SRC
** Dired and ranger
#+BEGIN_SRC elisp
(after! ranger
  (setq ranger-cleanup-eagerly t)
  (setq ranger-show-hidden t))
#+END_SRC
** Compilation
Add keybind to recompile (inside the buffer)
#+BEGIN_SRC elisp
(map!
 (:map 'compilation-mode-map
  :n "u" #'recompile))
#+END_SRC
** Company
#+BEGIN_SRC elisp
(add-hook
 'company-mode-hook
 #'(lambda () (setq company-frontends '(company-preview-frontend company-pseudo-tooltip-frontend))))
#+END_SRC
* Language Config
Configuration for various languages which I feel can be useful
** C-style languages
Configuration for C and C++.
*** User c-style
Emacs doesn't have the full range of styles that I want, so lemme just do it myself.
#+BEGIN_SRC elisp
(after! cc-mode
  (c-add-style
   "user"
   '((c-basic-offset . 2)
     (c-comment-only-line-offset . 0)
     (c-hanging-braces-alist (brace-list-open)
                             (brace-entry-open)
                             (substatement-open after)
                             (block-close . c-snug-do-while)
                             (arglist-cont-nonempty))
     (c-cleanup-list brace-else-brace)
     (c-offsets-alist
      (statement-block-intro . +)
      (knr-argdecl-intro . 0)
      (substatement-open . 0)
      (substatement-label . 0)
      (access-label . 0)
      (label . 0)
      (statement-cont . +))))
  (setq c-default-style "user"))
#+END_SRC
** Python
- I do python development for Python3, so I need to set the flycheck python checker, as well as the interpreter, to be Python3
- Most of my python work is in scripts or ideas, so I don't need extensive testing utilities or anything like that
- I run my python code a LOT and thus need commands for sending bits or whole scripts into the REPL
#+BEGIN_SRC elisp
(after! python
  (setq python-version-checked t)
  (setq python-python-command "python3")
  (setq python-shell-interpreter "python3")
  (setq flycheck-python-pycompile-executable "python3")

  (map! ; Python keybinds
   :map python-mode-map
   :localleader
   :desc "Start python minor" "c" #'run-python

    :desc "Send buffer"      "b" #'python-shell-send-buffer
    :desc "Send function"    "f" #'python-shell-send-defun)))
#+END_SRC
** Typescript
- Typescript (in my opinion) should be indented by 2
- Setup the LSP server on the lsp-language-id-config in case it hasn't already
#+BEGIN_SRC elisp
(after! typescript-mode
  (setq typescript-indent-level 2)
  (setq tide-format-options '(:indentSize 2 :tabSize 2))
  (after! lsp
    (cl-pushnew '(typescript-mode . "typescript") lsp-language-id-configuration :key #'car)
    (lsp-register-client
     (make-lsp-client
      :new-connection (lsp-stdio-connection "typescript-language-server --stdio")
      :major-modes '(typescript-mode)
      :server-id 'typescript))))
#+END_SRC
** Org
Org configuration to maximise org workflow.
*** Org variables
Setup the agenda-files and the org-directory.
#+BEGIN_SRC elisp
(after! org
  (add-hook 'org-mode-hook #'visual-line-mode)
  (add-hook 'org-mode-hook #'org-toggle-latex-fragment)
  (setq org-directory "~/Text"
        org-agenda-files '("~/Text/")
        org-src-window-setup 'split-window-right
        org-superstar-headline-bullets-list '("◉" "‣" "⧈" "⬠")
        org-log-repeat 'note))
#+END_SRC
*** Fragtog
#+BEGIN_SRC elisp
(use-package! org-fragtog
  :config
  (add-hook 'org-mode-hook #'org-fragtog-mode))
#+END_SRC
*** Thesaurus
Powerthesaurus installation, added a keybind in org-mode for looking up words.
#+BEGIN_SRC elisp
(use-package! powerthesaurus
  :after-call (org-mode)
  :defer-incrementally (org)
  :config
  (map!
   :localleader
   :map org-mode-map
   :prefix "w"
   :desc "Thesaurus" "t" #'powerthesaurus-lookup-word-at-point))
#+END_SRC
Powerthesaurus for thesaurus on writer files
*** Org keymap
- I like using org-export often, so bind it to a primary bind.
- Loading latex fragments is nice
#+BEGIN_SRC elisp
(map! ; Org keybinds
 :after org
 :map org-mode-map
 :localleader
 :desc "Org dispatch"        "e" #'org-export-dispatch
 :desc "Org LaTeX"           "E" #'org-latex-export-as-latex)
#+END_SRC
** Haskell

 :map haskell-mode-map
 :localleader
 "l" #'haskell-process-load-file
 "r" #'haskell-process-reload
 "o" #'haskell-process-start)
#+END_SRC
** Sxhkd
Define a major-mode for sxhkd config files.
#+BEGIN_SRC elisp
(define-generic-mode sxhkd-mode
  '(?#)
  '("alt" "Escape" "super" "bspc" "ctrl" "space" "shift" "hyper" "XF86*")
  '("{" "}")
  '("sxhkdrc")
  nil
  "Simple mode for sxhkdrc files.")
#+END_SRC
* Key-map
General keymap
** Personal
- Prefix "SPC m" (rebound from local-leader) that will hold personal keybinds for functions that I like using
- Mostly opening directories I use a lot or doing custom stuff that I can't really put in anything in particular
#+BEGIN_SRC elisp
(map!
 :leader
 :prefix ("m" . "personal") ; Personal
 :desc   "Open books"         "b"  #'(lambda () (interactive) (dired (concat org-directory "/Books"))); I like my books
 :desc   "Convert auto-fill"  "f"  #'dx:org/fill-to-long-lines
 :desc   "Change theme"       "t"  #'dx:themes/set-new-theme ; From my own collection
 :desc   "Generate template"  "g"  #'+gentemplate/generate-template) ; From my own collection
#+END_SRC
** Counsel
- Counsel keybind config
- Mostly just convenience stuff that happens to use counsel
#+BEGIN_SRC elisp
(map!
 :leader
 (:prefix ("s" . "search")
  :desc "RipGrep!"           "r"     #'counsel-rg ; Ripgrep is faster than Ag in most cases and makes me feel cool
  :desc "Search Tags"        "t"     #'counsel-etags-find-tag)); is quicker to do than <SPC>/b, for something that is done so often
#+END_SRC
** Window
- Keybinds to do with windows
- SPC wc < SPC wd
- Some ace-window config in the window keybind prefix
#+BEGIN_SRC elisp
(map!
 :leader
 :prefix ("w" . "window") ; Windows
 :desc "Close window"       "d"       #'+workspace/close-window-or-workspace ; is slightly closer together than <SPC>wc
 :desc "Switch window"      "w"       #'ace-window ; is also used in spacemacs so I'd rather use this
 :desc "Swap windows"       "S"       #'ace-swap-window) ; allows me to switch windows more efficiently than before, better than just motions
#+END_SRC
** Code
- Some keybinds for the code prefix which help me with coding or working with code, particularly LSP
#+BEGIN_SRC elisp
(map!
 :leader
 :prefix ("c" . "code") ; Code
 :desc "Compile"            "c"       #'compile

#+END_SRC
** Projectile
- Projectile config, for leader and for project prefix
#+BEGIN_SRC elisp
(map!
 :leader
 :after projectile
 :desc   "Switch to p-buffer" ">"     #'projectile-switch-to-buffer ; Opposing <SPC>< which counsel's all buffers

  :desc "Regen tags"         "g"     #'projectile-regenerate-tags
  :desc "Open project files" "f"     #'projectile-find-file))
#+END_SRC
** Fonts
- Fonts keybinds (prefix "z") for messing with fonts temp on a buffer
- Really useful when I need to zoom into something for whatever reason
#+BEGIN_SRC elisp
(map!
 :leader
 :prefix ("z" . "font") ; Fonts
 :desc "Increase font"  "+"           #'doom/increase-font-size

#+END_SRC
** Frames
- Keybinds for frame manipulation:
  - Generate new frames from current buffer
  - Generate new frames from a specific buffer
  - Delete frames
  - Switch frames
#+BEGIN_SRC elisp
(map!
 :leader
 :prefix ("F" . "frame") ; Frames
 :desc "Kill frame"           "d"     #'delete-frame

#+END_SRC
** Remaps
Adding a new configuration option.
Remapping functions that other modules set to default functions.

#+END_SRC
** Other
*** Leader
Miscellaneous leader bindings that don't really fit into any particular item
#+BEGIN_SRC elisp
(map!
 :leader
 :desc   "M-x"               "SPC"  #'execute-extended-command ; Redefine as M-x because of my muscle memory with spacemacs
