+#+TITLE: Literate configuration
+
+* 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.
+* 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
+(setq oreodave/literate/bin-dir (expand-file-name (concat doom-private-dir "bin/")))
+(setq oreodave/literate/preloaded-files (list "README.org" "org/packages.org"
+                                              "org/config.org" "org/literate.org"))
+#+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 oreodave/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 oreodave/literate/destination(SRC)
+  "Parse a src.org file to a bin/src.el file"
+  (replace-regexp-in-string ".*/\\(\\w+\\).org"
+                            (expand-file-name (concat oreodave/literate/bin-dir "\\1.el")) SRC))
+#+END_SRC
+* Parser
+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 oreodave/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
+            (or (and (zerop (call-process
+                             "emacs" nil output nil
+                             "-q" "--batch"
+                             "-l" "ob-tangle"
+                             "--eval" (format "(org-babel-tangle-file %S %S)"
+                                              SRC DEST)))
+                     (with-current-buffer output
+                       (message "%s" (buffer-string))
+                       t))
+                (warn (format "Problem with tanging %S to %S" SRC DEST)))
+          (kill-buffer output))))))
+#+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 oreodave/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")))))
+    (oreodave/literate/tangle buffer-file-name (oreodave/literate/destination buffer-file-name))))
+
+(after! org
+  (add-hook 'after-save-hook #'oreodave/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 oreodave/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)
+      (oreodave/literate/tangle file (oreodave/literate/destination file)))))
+#+END_SRC
+* Load configuration
+Final step of the literate cycle: load the config for the first time.
+Remove the config.el and literate.el files from the load list because:
+1) config.org is preloaded by doom
+2) literate.org is loaded by config.org, thus no need to reload it
+
+#+BEGIN_SRC elisp
+(let ((files (directory-files-recursively "~/.doom.d/org/" ".org"))) ; Load
+    (dolist (file (oreodave/literate/remove-mult oreodave/literate/preloaded-files files))
+      (load (oreodave/literate/destination file))))
+#+END_SRC
