#+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
possibe. It is currently my main C# and Python editor but hopefully it will
become my C one soon!
* Keybinds and tricks
|-------------+----------------------------------------------------------------------------------------------------------+-----------------|
| Bind        | Use                                                                                                      | Context         |
|-------------+----------------------------------------------------------------------------------------------------------+-----------------|
| *<C-c '>*   | To edit a src block                                                                                      | Org             |
| *<C-c C-o>* | To read the buffer results into a traversible buffer, so you can read it and do normal vim stuff with it | Counsel         |
| *<C-c C-p>* | To edit results buffer. You can edit specific items or the entire thing using a regex. Incredibly useful | Counsel results |
| *<C-o>*     | When you've gone to some line or definiton, go back to previous place                                    | Normal          |
| *<C-x h>*   | Mark whole buffer for copying                                                                            | Normal          |

* Global variables
#+BEGIN_SRC emacs-lisp
(setq doom-localleader-key ",")
(setq projectile-tags-command "exctags -Re --exclude=Makefile --exclude=node_modules --exclude=bin --exclude=obj --exclude=dist")
(setq warning-minimum-level :emergency)
(setq completion-ignore-case t)
#+END_SRC
- '<SPC>m' is right next to ',', so may as well use one tap instead of two
- Projectile tags commands

* Theming
#+BEGIN_SRC emacs-lisp
(load-theme 'doom-molokai t)
#+END_SRC
I like monokai :)

* General keymap
#+BEGIN_SRC emacs-lisp
(map!
 :leader
 :desc   "M-x"                "<SPC>" 'counsel-M-x
 :desc   "Indent"             "j"     'indent-region
 :desc   "Open project files" "pf"    'projectile-find-file
 :desc   "Compile via make"   "cC"    '+make/run
                                        ; Redefine <SPC><SPC> as M-x rather than find-file because of my muscle memory with spacemacs
                                        ; General maps like <SPC>j for indenting because I don't know what else to bind them to
                                        ; <SPC>pf => project -> find file
 (:prefix "/" ; Search
   :desc "Ag!"                "a"     '+ivy/ag
   :desc "FZF!"               "f"     'counsel-fzf
   :desc "RipGrep!"           "r"     'counsel-rg
   :desc "Search Tags"        "t"     'counsel-etags-list-tag
   :desc "Search buffer"      "/"     'swiper
   )
                                        ; I like using <SPC>/ in comparison to <SPC>s: it's closer together (thus quicker, I do searches a lot so this is noticeable) and makes more sense
                                        ; Ripgrep is faster than Ag in most cases and makes me feel cool
                                        ; <SPC>// is quicker to do than <SPC>/b, for something that is done so often

 (:prefix "w" ; Windows
   :desc "Close window"       "d"     '+workspace/close-window-or-workspace
   :desc "Switch window"      "W"     'ace-window

   )
                                        ; <SPC>wd is slightly closer together than <SPC>wc
                                        ; <SPC>wd is also used in spacemacs so I'd rather use this
                                        ; <SPC>wW allows me to switch windows more efficiently than before, better than just motions

 (:prefix "b"
   :desc "Close buffer"       "d"     'doom/kill-this-buffer-in-all-windows
   )
                                        ; <SPC>bd is used for the same reasons as above

 (:prefix "p"
   :desc "Regen tags"         "g"     'projectile-regenerate-tags
   )
 )
; <SPC>pg for regenning tags is useful when searching them
#+END_SRC
* Custom
** Packages and functionality
*** Wakatime
#+BEGIN_SRC emacs-lisp
(setq wakatime-api-key (shell-command-to-string "pass Keys/Wakatime"))
#+END_SRC
Using new password holder (pass) to help with secure transactions.
*** Dash
#+BEGIN_SRC emacs-lisp
(setq dash-docs-docsets-path "~/.docsets")
#+END_SRC
My docsets are stored in .docsets for ease of use
*** Frame management
#+BEGIN_SRC emacs-lisp
(map!
 :leader
 ; TODO think of a new prefix or leave and justfiy this one
 :prefix ("m" . "Frame") ; Literally the first free prefix I could think of
 :desc "Kill frame"                  "d" 'delete-frame
 :desc "Make current buffer frame"   "m" 'make-frame
 :desc "Choose buffer to make frame" "n" 'display-buffer-other-frame
 :desc "Switch frames"               "o" 'other-frame
 )
#+END_SRC
- This is my config for handling new frames
- I've only recently found out about them, they're incredibly powerful tools
  that I should've put in my toolbox a LONG time ago
*** Font size
#+BEGIN_SRC emacs-lisp
(map!
 :leader
 :prefix ("z" . "Font") ; using this prefix due to spacemacs
 :desc "Increase font"  "+" 'doom/increase-font-size
 :desc "Decreease font" "-" 'doom/decrease-font-size
 :desc "Adjust font"    "z" 'text-scale-adjust
 )
#+END_SRC
** Languages
*** C#
#+BEGIN_SRC emacs-lisp
(after! csharp-mode
  (setq omnisharp-server-executable-path "~/bin/omnisharp/run")
  (add-hook 'csharp-mode-hook '(lambda() (setq c-basic-offset 4))) ; Hook for csharp setting variables

  (map! ; CSharp Keybinds
   :map csharp-mode-map
   :localleader
   :desc   "Format buffer"  "="    'omnisharp-code-format-entire-file
   (:prefix "t"
     :desc "Unit Test This" "t"   'omnisharp-unit-test-at-point
     :desc "Unit Test Last" "l"   'omnisharp-unit-test-last
     :desc "Unit Test All"  "b"   'omnisharp-unit-test-buffer
     )
   )
  )
     #+END_SRC
- 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 :)
- Currently the Doom Emacs keybinds are not working for C# Unit-tests so I had to do them myself
- I find these keybinds to be more mnemonic (,mtt => Test -> This)
*** Python
#+BEGIN_SRC emacs-lisp
(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 "Format buffer"      "=" 'py-yapf-buffer
   (:prefix "s"
     :desc "Send region REPL" "r" 'python-shell-send-region
     :desc "Send buffer"      "b" 'python-shell-send-buffer
     :desc "Send function"    "f" 'python-shell-send-defun
     )
   )
  )
#+END_SRC
- I do python development for Python3 (who doesn't?), so I need to set the flycheck python checker, as well as the interpreter, to be Python3
- Python keybinds
- 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
*** JavaScript/TypeScript
#+BEGIN_SRC emacs-lisp
(after! typescript-mode
  (setq typescript-indent-level 2)
  (setq tide-format-options '(:indentSize 2 :tabSize 2))
  (map!
   :localleader
   :map typescript-mode-map
   :desc "Format code" "=" 'tide-format
   )
  )
#+END_SRC
- Typescript (in my opinion) should be indented by 2
- I like having one keybind to format a file, thus need to rebind
*** Org
#+BEGIN_SRC emacs-lisp
(after! org
  (map! ; Org keybinds
   :map org-mode-map
   :localleader
   :desc "Org dispatch" "ee" 'org-export-dispatch
   )
  )
#+END_SRC
I like using the org dispatch facilities more than the default export keybinds
in Doom, so I need this binding
