features and use cases
- full GTD implementation with
org-modeto help me stay organized - unified interface for common linux tools (dired, shell, git, ediff)
- fully customizable email client with

- document preparation with latex
for new users
Feel free to take bits and pieces for your own configuration file. Like many things in emacs, the config file is quite self documenting; however, there are some useful ramblings that decribe why I made some design choices over others. As someone who learned from countless emacs configs of other experienced users, I thought it was extremely beneficial to see the thought process behind their workflow and code, and I hope my annotations pay that forward. Finally, please don't just blindly copy this config into your ~/.emacs.d. I don't care if you do, but you will learn more if you build from scratch.
config structure
The "config file" is actually two files.
The "root" is init.el which is the file explicitly loaded by emacs. Most users have their entire config in this file but I put most of my actuall settings in another file as explained in the next paragraph. Here init.el has minimum functionality, including setting the repositories, configuring use-package (which installs all other packages and ensures they are available, useful if I move this elsewhere), and load paths for other config file.
Once loaded, the init.el pulls in another file called conf.el with the function org-babel-load-file. conf.el is actually sourced from an org file called conf.org.
Using an org file like this offers several advantages. First, org files are foldable in emacs which makes navigation easy. Second, they allow code snippets (the bit that actually go into conf.el) which allows for explanatory prose to be written around them, making documentation easy and clear. Third, org-mode has an automatic table of contents through the toc-org package, which makes naviagation even easier. Fourth, github itself is awesome enough to recognize org files as valid markdown and will render all the text, code snippets, headers, and table of contents in the nice html that you are reading now if on github. The result is a nearly self-documenting, self-organizing configuration that is easy to maintain and also easy to view for other users. Using the init.el itself would just have plain eLisp, which gets cluttered quickly. Some people break the init.el down into multiple files to keep everything sane, but I personally think it is easier to use one giant file that itself can be folded and abstracted to reduce the clutter.

overview
This section is meant to be a big-picture overview of how GTD works in this setup. For specifics, see each section following this for further explanation and code. I should also say that most of the ideas for the code came from Bernt Hansen's very detailed guide.
workflow
GTD as described in its original form is divided into five steps as explained further below. Here I attempt to explain how I implement each of these into org-mode.
collect
The whole point of GTD is to get stuff out of one's head, and this is purpose of the collect step. Basically if a thought or task pops in my head or interrupts me, I record it somewhere. These thoughts can happen any time and anywhere, so it is important to keep them out of consciousness so that I can concentrate on whatever I am doing.
When org-mode is in front of me, I use org-capture (see below for org-capture-templates). The "things" that could be collected include anything from random ideas, things I remember to do, appointments I need to attend, etc. I also capture emails with mu4e (which links to org-mode through org-protocol). Everythign collected with org-capture gets sent to a dedicated file where I deal with it later (see process step).
When org-mode is not in front of me, I record my thoughts in the Orgzly app on my android. It doesn't really sync so I transfer everything manually.
process
Collecting only records things; it doesn't make decisions. The point of the process step is to decide if the task/note is worth my time and when. This involves several key questions.
The first question to ask is if the task is actionable. If yes, it gets moved to a project file or a general task file. If not, I ask it can either be moved to the "incubator" (a place for things I might do), be moved any number of reference files (for storing inportant information), or flat-out deleted if I think it is stupid or no longer relevant.
In org-mode these decisions are made and recorded by moving headings between files with org-refile. To facilitate this process I have an agenda view to filter out captured tasks. From there it is easy to refile to wherever the headers need to go.
This step happens daily along with organize below.
organize
The organize step is basically the second half of the process step (I honestly think of these as a single task because that's how they are implemented in org-mode, but the original GTD workflow describes them seperately).
After refiling with org-refile, the next step is to add any remaining meta information to each task, which is later used to decide what to do and when. This information includes context, effort, delegation, and timestamps. In the case of projects this also includes choosing a NEXT tasks if one hasn't been chosen already.
Delegation (assingning something to someone else) is simple and is represented by a simple property which is filled with the initials of the person doing the work. It filter and view this with org-columns and org-agenda-columns.
When tasks don't have a specific date, GTD outlines a four-criteria model for deciding what to do: context, required time, available energy, and priority. Context describes required locations and resources for tasks, and I represent them with tags (see org-tags-alist). Required time is represented by the Effort property (see org-default-properties below). Available energy is subjective and not represented in org-mode. Priority is again represented with tags, here chosen from one of seven "life categories."
In assigning timestamps, org-mode offers several possibilities out of the box. Putting a plain active timestamp denotes an appointment (something at which I need to show up). A scheduled timestamp denotes a task that I want to work on starting at a certain time. A deadline denotes a task that must be finished by a certain time. I try to only use these for "hard" times as anything "soft" risks me not fulfilling to the timestamp and hence diminishing the value of timestamps in general.
I have three main agenda views for handling this. The first is a daily view that shows the tasks needed for today, including anything with a timestamp. The second has all tasks that are not timestamps (eg things that can be done at any time). The third is a project view that shows the top level headings for collections of tasks (this is where I find any projects that need a NEXT task).
The organize step may seem like it requires alot of work but luckily org-mode allows enough automation that some of this meta information can be added in the collect and process phases. For instance, timestamps and tags can be added (forcibly) in org-capture depending on what template is used. Furthermore, the priority tag and some context tags are added when the task is refiled to its proper file or project; this happens via tag inheritance, defined at either the file level or a parent heading (for instance, a computer-related tasks may be filed under environmental/computer where environment has the _env tag and computer has the #laptop tag).
review
In order to keep the entire workflow moving smoothly, it is necessary to do a high-level review.
This happens weekly and involves several things.
- Scheduling important tasks and resolve conflicts. For this I use
calfw(basically a calendar) to look at the next week and check if anything overlaps and move things around. I also "reload" repeater tasks usingnd/org-clone-subtree-with-timeshift. - Moving tasks to the archive as they are available. This keeps
org-modefast and uncluttered. - Reviewing the incubator and moving tasks out that I actually decide to do.
- Reviewing reference material and moving it to appropriate tasks.
- Assessing projects based on their status (see below for the definition of "status"). Ideally all projects are "active," and if they are not I try to make them active by assigning NEXT.
I have specialized agenda views and commands for facilitating all of this.
execute
Execute involves doing the predefined work laid out in the previous four steps. Generally I work through two agenda views (in order). The first being all my tasks that need to get done in the day, and the second being all tasks with no specific timestamp.
Besides physically doing the tasks here, the other special thing in org-mode that I use is clocking. In addition to tracking time spent, it also encourages clean breaks between tasks (eg no multitasking).
file hierarchy and structure
All org files are kept in one place (see org-directory). This is futher subdivided into directories for project (as per terms and definitions, these are any tasks that involve at least on subtask) and reference files. At the top level are files for incubated tasks, captured tasks, and catchall general tasks (which also includes small projects that don't fit anywhere else).
In order to make sorting easier and minimize work during processing, the files are further subdivided using tags at the file level and heading level that will automatically categorize tasks when they are refiled to a certain location. For example, some project may be to create a computer program, so I would set #+FILETAGS: #laptop because every task in this project will require a laptop. See the tags section below for more information on tags.
repetition
This deserves special attention because it comprises a significant percentage of tasks I do (and likely everyone does). I personally never liked the org's repeated task functionality. It is way too temporally rigid to be useful to me, and offers very little flexibility in mutating a task as it moves forward. Habits (which I use) are a partial fix for the first problem but do not aleviate the mutability problem.
My (somewhat convoluted) solution was to use org-clone-subtree-with-time-shift, which creates an easy way to make repeated tasks from some template, but also allows modification. The only problem with the vanilla implementation is that it lacks automation and agenda-block awareness (they all get treated as regular tasks which I don't want). This is partially fixed with my own nd/org-clone-subtree-with-time-shift which automaticlly resets tasks which are cloned (eg clearing checkboxes and resetting todo state). The remainding problems I fixed by defining several properties to be applied to repeated groupings under a heading (see properties).
The first property is called PARENT_TYPE and has two values iterator and periodical. The first applies to repeated tasks and second which applies to timestamped headings such as appointments. These are mostly useful for agenda sorting, where I have views specifically for managing repeated tasks. The second property is TIME_SHIFT; nd/org-clone-subtree-with-time-shift is aware of this value and automatically shifts cloned tasks accordingly if available.
In practice, I use this for tasks like workouts, paying bills, maintenance, grocery shopping, work meetings, GTD reviews, etc. These are all almost consistent but may change slightly in their timing, action items, effort, context, etc. If any of these change, it is easy enough to modify one heading without disrupting the rest.
In an org tree these look like this:
***** clean room
:PROPERTIES:
:PARENT_TYPE: iterator
:TIME_SHIFT: +1m
:END:
****** DONE clean room [0/2]
CLOSED: [2018-11-21 Wed 22:13] SCHEDULED: <2018-10-29 Mon>
:PROPERTIES:
:Effort: 0:15
:END:
- [ ] vacuum
- [ ] throw away trash
****** TODO clean room [0/2]
SCHEDULED: <2018-11-29 Thu>
:PROPERTIES:
:Effort: 0:30
:END:
- [ ] vacuum room
- [ ] throw away trashblock agenda views
The heart of this implementation is an army of block agenda views (basically filters on the underlying org trees that bring whatever I need into focus). These have become tailored enough to my workflow that I don't even use the built-in views anymore (I also have not found an "easy" way to turn these off). Besides projects, these agenda views are primarily driven using skip functions.
projects
When it comes to the agenda view, I never liked how org-mode by default handled "projects" (see how that is defined in "terms and definitions"). It mostly falls short because of the number of todo keywords I insist on using. The solution I implemented was to used "statuscodes" (which are just keywords in lisp) to define higher-level descriptions based on the keyword content of a project. For example a "stuck" project (with statuscode :stuck) is a project with only TODO keywords. Adding a NEXT status turns the statuscode to :active. Likewise WAIT makes :waiting. This seems straightforward, except that NEXT trumps WAIT, WAIT trumps HOLD, etc. Furthermore, there are errors I wish to catch to ensure subtrees get efficiently cleaned out, such as a project heading with DONE that still has a TODO underneath.
I used to take care of this problem with lots of skip functions, but it turned out to be unmaintainable and offered poor performance (eg if I wanted a block agenda for N statuscodes, I needed to scan the entire org tree N times). A far easier way to implement this was to embed the statuscodes in text properties in each agenda line, which could then be sorted and the prefix string formatted with the status code for identification in the block agenda view. Since this only requires one block, it only requires one scan, and is very fast.
repeaters
Similarly to projects, repeaters (eg iterators and periodicals) are assessed via a statuscode (after all they are a group of headings and thus depending on the evaluation of todo keywoards and timestamps in aggregate). These prove much simpler than projects as essentially all I need are codes for uninitialized (there is nothing in the repeater), empty (all subheadings are in the past and therefore irrelevant), and active (there are some subtasks in the future).
terms and definitions
These conventions are used throughout to be precise when naming functions/variables and describing their effects
headings
- heading: the topmost part after the bullet in an org outline. Org-mode cannot seem to make up it's mind in calling it a header, heading, or headline, so I picked heading
- todoitem: any heading with a todo keyword
-
task: a todoitem with no todoitem children
- atomic: further specifies that the task is not part of a project
-
project: a todoitem with that has todoitem children or other projects
- status(code): a keyword used to describe the overall status of a project. See skip functions in the block agenda section for their implementation.
time
-
stale: refers to timestamps that are in the past/present
- archivable: further specifies that the timestamp is older than some cutoff that defines when tasks can be archived (usually 30 days)
- fresh: refers to timestamps that are in the future
todo states
sequences
These keywords are used universally for all org files (see below on quick explanation for each, they are all quite straightforward). Note that projects have a more specific meaning for these keywords in defining project status (see the library of agenda function). Also, it looks way better in the agenda buffer when they are all the same number of chars.
In terms of logging, I like to record the time of each change upon leaving any state, and I like recording information in notes when waiting, holding, or canceling (as these usually have some external trigger or barrier that should be specified).
(setq org-todo-keywords
'((sequence
;; default undone state
"TODO(t/!)"
;; undone but available to do now (projects only)
"NEXT(n/!)" "|"
;; done and complete
"DONE(d/!)")
(sequence
;; undone and waiting on some external dependency
"WAIT(w@/!)"
;; undone but signifies tasks on which I don't wish to focus at the moment
"HOLD(h@/!)" "|"
;; done but not complete
"CANC(c@/!)")))colors
Aesthetically, I like all my keywords to have bold colors.
(setq org-todo-keyword-faces
'(("TODO" :foreground "light coral" :weight bold)
("NEXT" :foreground "khaki" :weight bold)
("DONE" :foreground "light green" :weight bold)

("CANC" :foreground "deep sky blue" :weight bold)))tags
alist
I use tags for agenda filtering (primarily for GTD contexts, see below). Each tag here starts with a symbol to define its group (note, only the special chars "_", "@", "#", and "%" seem to be allowed; anything else will do weird things in the hotkey prompt). Some groups are mutually exclusive. By convention, any tag not part of these groups is ALLCAPS (not very common) and set at the file level.
(setq org-tag-alist

Each group also has its own color, defined by its prefix symbol.

Refiling is easiest to do from a block agenda view (see below) where headings can be moved in bulk.

general
Clocking is still new and experimental (I'm not a ninja like Bernt yet). I mostly use clocking now as a way to make clean breaks between tasks (eg to discourage "mixing" tasks which is a slippery multitasking slope). I bound F4 to org-clock-goto as an easy way to find my current/last clocked task in any mode (see keybindigs).
(setq org-clock-history-length 23
org-clock-out-when-done t
org-clock-persist t
org-clock-report-include-clocking-task t)modeline
The modeline is a nice place to indicate if something is clocked in or out. Unfortunately, sometimes is is so crowded that I can't see the text for the currently clocked task. Solution, use colors.

Somehow org-mode has no way to detect conflicts between tasks with timestamps (!!??). Luckily I can make my own.
backend
The algoithm to detect conflicts scans all org files and stores conflicts in a list of pairs of each heading with a conflicting timestamp.
Steps for this algorithm:
- make a list of all entries with timestamps
- sort timestamp list
- Walk through list and compare entries immediately after (sorting ensures that entries can be skipped once one non-conflict is found). If conflicts are found push the pair to a new list (this is what is used to make the display)
This should be O(n) (best case/no conflicts) to O(n^2) (worst case/everything conflicts)

To display any conflicts, I could just fetch the org headings and throw them into a new buffer. But that's boring, and quite limiting. I basically want all the perks of an agenda buffer…tab-follow, the nice parent display at the bottom, time adjust hotkeys, etc. So the obvious and hacky solution is to throw together a quick-n-dirty agenda buffer which displays each conflict pair in sequentional fashion.

As it is, this allows any filter using hasprop to be applied and removed using the standard org-agenda-filter-apply function with the org-agenda-hasprop-filter variable (obviously these can all be extended to different filter types). Note this does not give a shiny indicator at the bottom of spaceline like the built-in filter does…oh well.

Some org functions don't do exactly what I want. Re-educate them here
The org-tags-view can filter tags for only headings with TODO keywords (with type tags-todo), but this automatically excludes keywords in org-done-keywords. Therefore, if I want to include these in any custom agenda blocks, I need to use type tags instead and skip the unwanted TODO keywords with a skip function. This is far slower as it applies the skip function to EVERY heading.
Fix that here by nullifying org--matcher-tags-todo-only which controls how the matcher is created for tags and tags-todo. Now I can select done keywords using a match string like "+tag/DONE|CANC" (also much clearer in my opinion).
While this is usually more efficient, it may be counterproductive in cases where skip functions can be used to ignore huge sections of an org file (which is rarely for me; most only skip ahead to the next heading).
