* overview
** features and use cases
- full [[https://en.wikipedia.org/wiki/Getting_Things_Done][GTD]] implementation with =org-mode= to help me stay organized
- unified interface for common linux tools (dired, shell, git, ediff)
- fully customizable email client with =mu4e=
- optimizations for some of my favorite languages (R, Lisp, Haskell, Lua, Python)
- 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 multiple files. 
*** init.el
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.
*** conf.org/conf.el
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 [[https://en.wikipedia.org/wiki/Org-mode][org-mode]] file called =conf.org= (this file).

Using an org file like this offers several advantages:
1. org files are foldable in emacs which makes navigation easy.
2. org files 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.
3. =org-mode= has an automatic table of contents through the =toc-org= package, which makes naviagation even easier.
4. 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.
*** personal modules
=conf.el= in turn also loads "personal modules" located in =local/lib=. These modules are effectively packages that I use only for myself (and may submit to an offcial repo if I clean them up and deem them general enough for more than just me).

In general, code from =conf.org= is moved into a module for any of several reasons:
1. They represent large sections of code that have a small public API (perhaps one interactive function that in turn calls 20 supporting functions).
2. They are worth testing independently 
3. They are worth byte-compiling independently (for speed and/or compile-time checks)
   1. In my experience =init.el= and =conf.el= aren't worth byte compiling because there are often many false-flag errors and scoping errors due to the order of loading certain components
4. The code might become an official package in the future
5. The code is executed inside some toplevel macro and I don't feel like indenting hundreds of lines
** continuous integration
In the root of this directory is a =.github= folder with some simple tests to ensure this config is 'valid'. I'm experimenting with this and it may not turn out to be worth it, but the main reason these exist is that I would like to ensure I can transfer my emacs config to another system and have it work with no problems.

The danger with only having emacs on my daily driver is that I could silently introduce a dependency on some system library, and this may or may not be present when I unpack this config on a different machine. For now, the CI pipeline simply tests whether or not this config will initialize and build correctly on a "bare" system, and also tests if I can pull a list of dependencies using my somewhat hacky [[#system-dependencies][API]] so they can be installed via the package manager.

The major mode package =haskell-mode= is quite comprehensive and has most of what I need out of the box, including:
- syntax highlighting
- indentation
- autocompletion
- flycheck integration
- type checking/insertion/annotation
- function info

Since most of these need GHCi to run properly, I added a hook to load haskell source into GHCi when opened.

I have also found this to be much simpler and conflicting with other packages such as =dante= and =intero= (and probably =haskell-ide-engine= and friends).

[[https://github.com/taskjuggler/TaskJuggler][TaskJuggler]] is software that is most likely used by some super-intelligent alien species to plan their invasions of nearby planets and develop sophisticated means of social control.

Basically it is really complicated and powerful. For now I use it to make cute gantt charts.

Taskjuggler is provided by an external package that provides the command line tools (available in the AUR for Arch Linux). Org-mode has "native" export support through a contrib module. I maintain a separate package with extra functions with taskjuggler web interface support in a separate package loaded here.

** gtd implementation
*** 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 [[http://doc.norang.ca/org-mode.html#OrgFileStructure][Bernt Hansen's]] very detailed guide.
**** workflow
GTD as described in its [[https://en.wikipedia.org/wiki/Getting_Things_Done][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=). Everything 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 phone. It doesn't sync the way I want 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 headlines 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 attention, available energy, and priority. Context describes required locations and resources for tasks, and I represent them with tags (see =org-tags-alist=). Required attention 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 headline for collections of tasks (this is where I find any projects that need a NEXT task).

The /organize/ step may seem like it requires too much 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 headline (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 using =org-x-clone-subtree-with-time-shift=.
- Moving tasks to the archive as they are available. This keeps =org-mode= fast 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.
- Reviewing inert tasks and projects (eg those with no recent activity) and moving them to the incubator if I don't deem them worthy of immediate attention (see below for definition of "inert").

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. If a clock is running on a headline, it means I'm paying attention to whatever that headline represents. This implies that multitasking isn't allowed, which is bad idea in general.
**** 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 headline 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 =org-x-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 headline (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 headlines 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=; =org-x-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 headline without disrupting the rest.

In an org tree these look like this:

**** block 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 headline with =DONE= that still has a =TODO= underneath.

For a full overview of how these statuscodes are implemented, see =org-x-headline-get-project-status=.
***** repeaters
Similarly to projects, repeaters (eg iterators and periodicals) are assessed via a statuscode (after all they are a group of headlings 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).

See =org-x-headline-get-iterator-status= and =org-x-headline-get-periodical-status= for how these statuscodes are implemented.
***** tasks
Tasks are mostly just defined by their todo keyword (or lack of one). Like projects and repeaters, I use statuscodes to do the agenda filtering, which is necessary to concisely keep track of not only the keywords but the timestamps and logbook status (for example, and "archivable" task is one that was completed a while ago and thus is ready to be archived).

See =org-x-headline-get-task-status= for this implementation.
**** terms and definitions
These conventions are used throughout to be precise when naming functions/variables and describing their effects
***** headlines
- headline: 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 headline
- todoitem: any headline with a todo keyword
- task: a todoitem with no todoitem children
  - atomic: a task is not part of a project
- project: a todoitem with that has todoitem children or other projects
  - toplevel: a project that has no parents that have todo items
***** time
- stale: headlines with timestamps that are in the past/present
  - archivable: like stale but further specifies the timestamp is older than a cutoff that defines when tasks can be archived (usually 30 days)
- fresh: headlines with timestamps that are in the future
- inert: tasks that have not had a recent clock or logbook entry, see =org-x-headline-headline-is-inert-p=

These keywords are used universally for all org files. Note that projects have a more specific meaning for these keywords in defining project status (see =org-x-headline-get-project-status=).

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).

;; advice

;; The `org-tags-view' can filter tags along with TODO keywords (eg 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 headline. 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).

** tracking and analytics

Because =org-mode= has rich metadata (clocking, logbook, tags, etc) and a robust long-term storage mechanism (archive which can be git-backed), it is a powerful lens with which to study one's own behavior.

Questions I am concerned with answering (non-exhaustive):
- What time of day am I most productive? (can be measured using =CLOSED= timestamps)
- How good am I at estimating how long projects will take (can be measured using clocks and the =Effort= property)
- How well do I follow my habits? (measured with logbook entries and the =SCHEDULED= timestamp on the habit)
  - Specifically, are there certain habits I tend to skip? If so, how long does it take before I start skipping them?
  - One important habit I track is sleeping. How consistent am in terms of start of sleep and length of sleep?
- How many tasks do I write down and then forget about? (use task creation time and tags/category/properties to classify into subgroups)
  - As an inverse corollary to this, what characteristics do the tasks I end up doing in a timely manner have in common?
- Which projects/life categories recieve most of my attention? (sum completed clocks and group by tag or project)
  
=org-mode= itself has a few utilities and 3rd-party packages for answering these questions directly in emacs, but they are limited in that they often only look at an isolated slice of all =org-mode= data within a limited time period (the agenda habit tracker for example, or column views in org buffers which can display clock summaries per project). I have data spanning years of time that I want to analyze comprehensively.

=org-sql= is a package that can store org files in a SQL database, which which one can perform whatever analysis they want. Obviously this isn't done in Emacs and is quite complicated, but the advantage of using a system like this is that SQL itself is meant purely to be a data language and many analysis tools understand it.

I personally store my data in a postgreSQL database. For analysis and visualization I use a combination of [[https://github.com/metabase/metabase][Metabase]] (which is automatically awesome because it's written in Clojure) and R scripts.

* keybindings
For the sake of my sanity, all bindings go here. Note this means I don't use =:bind= in use-package forms.
** setup
Most of my modifiers are reloacted using xkb and [[https://github.com/alols/xcape][xcape]].

The xkb layout can be found [[https://github.com/ndwarshuis/xkb-hypermode][here]].

Below is a summary of the remapped xcape keys.
