+#+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 local-leader to "SPC ," because it's faster
+- Good font choices:
+  - Hack
+  - Source Code Pro/Variable
+  - IBM Plex Mono
+  - Space Mono
+  - Z003 if I'm feeling fancy (▀̿Ĺ̯▀̿̿)
+#+BEGIN_SRC elisp
+(after! core-keybinds
+  (map! :leader "," nil)
+  (setq doom-localleader-key "SPC ,")
+  (setq doom-themes-enable-italic nil)
+  (setq doom-themes-enable-bold t)
+  (setq doom-theme 'doom-monokai-classic)
+  (setq doom-font (font-spec :family "Source Code Pro" :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
+  truncate-lines t
+  display-line-numbers-type t
+  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 . 90))
+(cl-pushnew '("Libgen" "http://gen.lib.rus.ec/search.php?req=%s") +lookup-provider-url-alist :key #'car :test 'string=)

+** HACK: Load org mode again?
+#+BEGIN_SRC elisp
+(load (expand-file-name (concat user-emacs-directory "modules/lang/org/config.el")))

+* Package Configuration
+Configuration for or based heavily around specific packages that I find very important
+** Ido
+Just add vimish keybindings to ido completion
+#+BEGIN_SRC elisp

+#+END_SRC
+** 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

+#+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.

+** Dired and ranger
+I like doing shell comamnds from dired, but I don't want Emacs to hang when doing them.

+#+TITLE: Literate configuration (NO LONGER IN USE)
+
+* Preclude
+My setup to produce a literate configuration.
+Allows me to write org files all around the /doom-private-dir/ and access them.
+Also shaved like 0.2s off my loading time.
+
+/Note/: My current literate system now uses the =org-babel-load*= functions to handle most of the hard work.
+It's easier to use and manage, and I just don't use that many org files anymore so no need for such a big setup.
+* Constants
+Initialise some basic constants for where stuff is.
+- literate/bin-dir: Where to compile to
+- literate/preloaded-files: Relative to ~$DOOM~, which files are already
+  preloaded/don't need to be compiled
+#+BEGIN_SRC elisp
+(defconst dx:literate/bin-dir (expand-file-name (concat doom-private-dir "bin/")) "Directory to store elisp compiled files")
+(defconst dx:literate/load-files '("~/.doom.d/org/personal.org") "Files to load after compilation")
+(defconst dx:literate/directory (expand-file-name (concat doom-private-dir "org/")) "Directory to get org files from")
+#+END_SRC
+* Remove function
+When loading the lisp, we need to load everything excluding "config.el" (preloaded by doom) and "literate.el" (loaded by "config.el").
+We'll make a very specific remove function that will remove entries from a given list and return the new list, given the fact that the files variable will be a list of fully expanded file names.
+#+BEGIN_SRC elisp
+(defun dx:literate/remove-mult (remove-files files)
+  "Remove any occurrences of `remove-files' from `files'"
+  (let ((parsed-remove-files (map 'list
+                                  #'(lambda (i) (expand-file-name (concat doom-private-dir i)))
+                                  remove-files))) ; Generate a list of all fully expanded files to remove
+    (remove-if #'(lambda (l) (member l parsed-remove-files)) files))) ; remove any files that are in the remove-files
+#+END_SRC
+* Destination for parser
+Generate the destination for a literate config org file to parse to, in this case the bin folder in the private directory.
+This is not fitted onto the parser because the parser could be fitted to multiple /differing/ outputs easily if it isn't specified a destination.
+#+BEGIN_SRC elisp
+(defun dx:literate/destination(SRC)
+  "Parse a src.org file to a bin/src.el file"
+  (replace-regexp-in-string ".*/\\(\\w+\\).org"
+                            (expand-file-name (concat dx:literate/bin-dir "\\1.el")) SRC))
+#+END_SRC
+* Parser
+** Tangle function
+First we need to get some sort of parser which can, given a source org file and a destination, parse and produce an Emacs lisp file.
+We'll copy this from the literate module of doom.
+#+BEGIN_SRC elisp
+(defun dx:literate/tangle (SRC DEST)
+  "Tangle a source org file into a destination el file using a new emacs instance"
+  (let ((default-directory doom-private-dir))
+    (when (file-newer-than-file-p SRC DEST)
+      (let ((output (get-buffer-create "*org-tangle*")))
+        (unwind-protect
+            (async-shell-command
+             (concat "emacs "
+                     "-q " "--batch "
+                     "-l " "ob-tangle "
+                     "--eval "
+                     (format "'(org-babel-tangle-file %S %S)'" SRC DEST))
+             "*org-tangle-messages*"
+             "*org-tangle-errors*"))))))
+#+END_SRC
+** Popup rules
+I don't want Emacs to focus onto the output buffer of the tangling process when I save, which is what happens with a standard async-shell-command.
+So setup a rule for the 'messages' and 'errors' buffers to not focus them (by setting their time to live to 0).
+#+BEGIN_SRC elisp
+(set-popup-rule! "\*org-tangle-.*" :ttl 0 :quit t)
+#+END_SRC
+* Hook on save
+Now we need to make a hook function that, when the current buffer is an org file in the doom directory, will run the literate config procedure from above.
+Use this hook function and add it to the after-save-hook once org mode has been loaded.
+README.org has been added as an exception because it doesn't contain literate contents.
+#+BEGIN_SRC elisp
+(defun dx:literate/compile-hook ()
+  "Any org file within $DOOM/org will be compiled on save"
+  (when (and (eq major-mode 'org-mode)
+             (or (file-in-directory-p buffer-file-name doom-private-dir)
+                 (file-in-directory-p buffer-file-name (concat doom-private-dir "org")))
+             (not (string= buffer-file-name (expand-file-name (concat doom-private-dir "README.org")))))
+    (dx:literate/tangle buffer-file-name (dx:literate/destination buffer-file-name))))
+
+(after! org
+  (add-hook 'after-save-hook #'dx:literate/compile-hook))
+#+END_SRC
+* Procedure for all files
+A procedure that parses all the org files in a given directory into Emacs lisp
+files, using the parser function made. Assume all org files in the "location"
+directory contribute to the config.
+The location is not set because this function could be easily programmed to use
+multiple /differing/ sources to produce the config. The tangle function is set
+because this is the function we'll be using for tangling all org files to ELisp files.
+#+BEGIN_SRC elisp
+(defun dx:literate/tangle-all (&optional location)
+  "Tangle all org files in `location' to el files in the `destination'"
+  (interactive)
+  (or location (setq location doom-private-dir))
+  (message "Starting compilation process")
+  (let ((files (directory-files-recursively location ".org")))
+    (dolist (file files)
+      (message "Compiling and parsing %s" file)
+      (dx:literate/tangle file (dx:literate/destination file)))))
+#+END_SRC
+* Load configuration
+Final step of the literate cycle: load the config for the first time. Load any org files in =dx:literate/load-files=.
+#+BEGIN_SRC elisp
+(dolist (file dx:literate/load-files)
+  (load (dx:literate/destination file)))

+** Tags
+Should really be an inbuilt feature for Ivy, as it is so damn useful.
+Better than the Helm or inbuilt "TAGS" searching options as it provides ways to quickly filter data from the tag set which makes it incredibly fast.

+* Change theme
+Allow user to set a theme from a limited set of candidates, based on "dx:theme-list".
+
+- Themes sanctioned by me:
+  - doom-solarized-dark: just the right everything. best for day.
+  - doom-gruvbox: good contrast, better for night.
+  - doom-city-lights: Eh contrast, quite dark
+  - doom-outrun-electric: Interesting colour palette
+  - doom-vibrant: Good contrast, bit lighter
+  - doom-molokai/doom-monokai-classic: hacker style
+  - doom-solarized-light: Light orange theme that's actually okay on the eyes
+  - doom-acario-light: Light theme with not bad colours
+- Themes not sanctioned:
+  - Light themes other than solarized-light and acario
+  - Horrid low contrast ones with no colour. Grayscale particularly. I can't
+    handle those.

+* Convert auto-fill lines to long truncate-lines
+Consider some org file with auto filled lines.
+I don't like auto-filled lines.
+So I want to convert them.
+I've setup macros countless times to do this operation for me, may as well formalize it as a function.
+
+Firstly, I need a function to count the number of instances of some substring occur in some other string.
+Shamelessly copied from rosetta code.
+#+BEGIN_SRC elisp
+(defun dx:org/count-sub (str pat)
+  (loop with z = 0 with s = 0 while s do
+        (when (setf s (cl-search pat str :start2 s))
+          (incf z) (incf s (length pat)))
+        finally (return z)))
+#+END_SRC
+
+Then the main function, works like so:
+1) Search the text in the region for newlines then join the lines to make a single segment
+2) Search for sentences through Emacs builtin =forward-sentence= and =forward-char= functions then newline via sentences
