#+TITLE: Oreodave's Emacs configuration
#+AUTHOR: Oreodave
#+DESCRIPTION: My Doom Emacs configuration!
#+PROPERTY: header-args :results none

* 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.
* Init
Initialize literate config and setup some basic variables
** Bootstrap
Load the literate.el file to start parsing.
#+BEGIN_SRC elisp
(load (expand-file-name (concat doom-private-dir "bin/literate.el")))
#+END_SRC
** 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
  (setq doom-localleader-key ",")
  (setq doom-theme 'doom-molokai)
  (setq doom-font (font-spec :family "Hack" :size 17)))
#+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 nil)
(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 . 85))
(cl-pushnew '("Libgen" "http://gen.lib.rus.ec/search.php?req=%s") +lookup-provider-url-alist :key #'car :test 'string=)
#+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/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)
        ("Check the weather"
         :icon (all-the-icons-wicon "rain" :face 'font-lock-keyword-face)
         :action dx:weather)
        ("Jump to bookmark"
         :icon (all-the-icons-octicon "bookmark" :face 'font-lock-keyword-face)
         :action bookmark-jump)))
#+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
** 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 still at least it's something.
#+BEGIN_SRC elisp
(setq +pretty-code-symbols '(:name "»"
                             :src_block "»"
                             :src_block_end "«"

                             :dot "•"))
#+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 add support for it.
#+BEGIN_SRC elisp
(after! cc-mode
  (set-pretty-symbols!

    :return "return"
    :or "||"
    :and "&&"

    :bool "bool"
    :str "string"
    :str "std::string"
    :float "float"
    :int "int"
    :false "false"
    :true "true"
    :null "nullptr"))
#+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

#+END_SRC
** LSP
Add lsp-ui-doc-mode to lsp-ui-mode: allows you to see documentation in a little
VSCode style web-kit window.
#+BEGIN_SRC elisp

  that
#+BEGIN_SRC elisp
(after! csharp-mode

#+END_SRC
*** Unit test over whole projects
- Implemented my own function which piggy backs counsel etags to globally search
  tags for test specific context, then goes to it and uses an omnisharp test
  command to unit test it. Basically global test search in C# projects. To use
  this, just make sure you have tags compiled and that all your tests are
  written as some public void *name* _Test (i.e. they are appended with _Test so
  that the pattern can be matched)
#+BEGIN_SRC elisp
(after! (csharp-mode counsel-etags)
  (defun dx:csharp/get-unit-test-in-project ()
    "Unit test anywhere using CTags or ETags and C#"

*** Redo omnisharp-emit-results
