Treefactor is an Emacs package that defines a joint org-mode/Dired workflow for restructuring your messy Org documents.
Treefactor breaks text into logical outline headings, then refiles those headings.
Treefactor conceptualizes the directory tree and outlines within files as one unified meta-outline. It facilitates restructuring that outline.
Rather than trying to refile from the current location to the final destination in one leap, Treefactor uses inductive incremental refiling. It rapidly refiles many objects in the right direction, one step at a time.
(If the above introduction was too abstract, and you're experienced with Emacs, then skip ahead to the Commands section. Then come back here.)
In practice, I only refactor Org files, since that's where I keep almost all my prose. Treefactor is therefore focused on Org mode. Many of Org's commands work on outlines in other modes. Treefactor may work on them as well.
In addition to headings, Treefactor can refile files in Dired. I use Treefactor when I need inductive sorting. Typically this means "user" files of the kind stored in ~/Documents, ~/Downloads, etc. These files cover a dynamic range of topics, so I categorize them inductively.
Inductive incremental refiling is useful when user knows the current information context well, but his knowledge degrades as distance from the current location increases.
This is quite common. For example, imagine you're moving to a new house. Right now you're packing up the old house. Do you know exactly where all your stuff should go at the new house? Of course not. You just pack up all the garage stuff into "garage" boxes, and defer finer organization until it's time to unpack them.
Treefactor is like a magic wand you point at the stuff in your garage. You say "garage," and it magically jumps into the garage box. It automates repetitive actions in the workflow.
Treefactor gives the user refiling commands that cover the smallest possible distance. The shorter a refile, the more likely it is to be an improvement rather than a mistake. Simple decisions are exponentially easier to make than complicated ones.
Treefactor's other commands are mostly tweaks to org-mode to support this workflow, which differs from Org's philosophy.
If you are learning about Treefactor for the first time, please read this site in the order listed on the Table of Contents sidebar. Each command has at least one gif demo that will help you understand what it does.
Treefactor's goal is inductive meta-outline evolution. I use Treefactor to manage my Textmind, a 1/3 gigabyte text exobrain Git repo that can comfortably process 10k words per day. Daily intake varies between 1-20k words, with 2.5k a typical number. I read a lot, and Treefactor has no trouble keeping up. Other personal information managers always choked on the volume.
With great power comes great responsibility. Treefactor is a power tool that quickly moves text and files around the directory tree. Please learn how it works before using it in production, or you may misfile important information.
