 *** Literate Programming
 
 My first Doom Emacs config was hacked together directly from the generated example config: no comments, no organization, nothing. ~after!~ and ~use-package!~ blocks were scattered about the file without rhyme or reason, making it very difficult to remember what any particular line of code was actually doing. I was able to mitigate some of this issue by categorizing my config into multiple files, but at the end of the day it was a losing battle. The config directory was at around 1200 lines of code before I decided that something needed to be done.
 
-I was considering what to do about this problem of organizational decay when I came across [[https://tecosaur.github.io/emacs-config/config.html][Tecosaur's config]] and learned about =org-mode='s literate programming support. I was very comfortable with =org-mode= at this point, so it seemed like a good solution and a natural next step.

+3. *Tasks*, which are one-time and contribute to goals or areas.
 
 Areas are stored as subnodes of the =Areas= file node, and likewise for goals. They also have the =:area:= and =:goal:= tags respectively. A task is a node that is a TODO entry that links to an area or a goal. We can thus check for if a node is a task by checking if the node links to a =:area:= or =:goal:= tagged node.
