#+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, which I try to use for as many things as
possible. It is currently my main editor overall, literally overtaking my life.
* Simple variables
Setting up variables and basic stuff that doesn't require a lot of work.
** Doom Variables
#+BEGIN_SRC elisp
(setq doom-localleader-key ",")
(setq doom-font (font-spec :family "Hack" :size 19))
(setq doom-theme 'doom-solarized-dark)
#+END_SRC
- Set the doom localleader to "," because it's faster
- Using the font [[https://sourcefoundry.org/hack/][Hack]] with Fira code ligatures
- I like Solarized dark
** Interface
#+BEGIN_SRC elisp
(setq completion-ignore-case t)
(setq truncate-lines t)
#+END_SRC
Some quality of life things that I couldn't really put in one category
**
** Org directory
#+BEGIN_SRC elisp
(setq org-directory "~/Text")
#+END_SRC
Set the org directory to Text.
** Search providers
#+BEGIN_SRC elisp
(cl-pushnew '("Libgen" . "https://libgen.me/search/all?search=%s") +lookup-provider-url-alist :key #'car)
#+END_SRC
Uniquely append "Libgen" to the search provider alist. Libgen is a nice book site.

                              +pretty-code-fira-code-font-name)))
(setq fancy-splash-image "~/Pictures/emacs-backgrounds/killerqueen.png")
#+END_SRC
- '<SPC>m' is right next to ',', so may as well use one tap instead of two
- Projectile tags commands
- killer queen image comes from this Reddit [[https://www.reddit.com/r/StardustCrusaders/comments/974qwh/fanart_killer_queens_shadow/][post]]

- I have custom installed the omnisharp roslyn executable, so I'd rather use that
- C# code is better at 4 space indents, but I indent most of my C code at 2 space indents because it looks nicer :)
- Reimplemented omnisharp emit messages for stdout
- 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

Doom has an amazing little function to do searches from inside Emacs alone.
Given a provider, it'll send some query via formatting the provider URL with the
query text, and open it on a default browser. I want to add some more items to
this provider set.
