Raw Blame History

* overview
This is my personal emacs config which currently runs on emacs 26.1 (currently the latest package from the Arch Linux official repos).
I use this for a variety of purposes:
- maintaining my todo list/[[https://en.wikipedia.org/wiki/Getting_Things_Done][GTD]] workflow (org mode)
- unified interface for system administration (dired, shell, git, ediff)
- email (mu4e, work in progress)
- editing some of my favorite languages (R, Lisp, Haskell, Lua, Python)

** window splitting
Org mode is great and all, but the windows never show up in the right place. The solutions here are simple, but have the downside that the window sizing must be changed when tags/capture templates/todo items are changed. This is because the buffer size is not known at window creation time and I didn't feel like making a function to predict it

** 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 asynchronous and synchronous workflows where the asynchronous components happen at any given time and the synchronous components happen on a set schedule. Org mode lends itself quite well to this, and the feature I primarily use in this implementation are custom agenda views (with lots of skip functions).
async:
1. capture (see =org-capture-templates= below)
- emails as I read them (mu4e)
- ideas that pop into my head
- tasks that I remember to do
- appointments/deadlines in the future
- interruptions from pointy-haired bosses
sync:
1. process (daily)
- decide if actionable/not
- assign to incubator, references, specific project, or general task file
2. organize (daily)
- add tags (context or resources)
- add properties (effort and delegation)
- note that some tags are automatically added in the proces stage above (mostly priority buckets used for the 7 areas of life, see tags below)
3. review (weekly)
- check project status
- check for scheduling conflicts
- move to/from incubator depending on how adevnturous I feel
4. doing (as planned)
- work through scheduled tasks and deadlines for day
- work through project tasks depending on context/effort/piority
- use clocking to track progress and encourage clean breaks b/t tasks
**** file hierarchy and structure
All org files are kept in one directory in =$HOME=. 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 =nd/org-clone-subtree-with-time-shift= (modifed original) which automaticlly cleans tasks which are cloned (for some reason the original does not clear checkboxes and such). 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:
#+BEGIN_SRC org
***** 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>

SCHEDULED: <2018-11-29 Thu>
:PROPERTIES:

:END:

#+END_SRC
**** 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 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
**** list
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.
#+BEGIN_SRC emacs-lisp
(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@/!)")))
#+END_SRC
**** colors

#+END_SRC
*** 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.
#+BEGIN_SRC emacs-lisp

*** properties

*** refile
Refile (like capture) should be fast, and I search all org file simultaneously using helm (setting =org-outline-path-complete-in-steps= to =nil= makes search happen for entire trees at once and not just the current level).

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).

*** conflict detection
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:
1. make a list of all entries with timestamps
2. sort timestamp list
3. 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.

In order to implement the =hasprop= filter, the functions =org-agenda-filter-make-matcher= and =org-agenda-filter-remove-all= need to be advised in order to add the functionality for the =hasprop= filter type.
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.

I like being evil. All package and custom bindings go here.

This is somewhat strange because all I really care about is moving between lines and to the beginning and end as normal. However, I like the idea of thinking of paragraphs as one line (eg df. deletes a sentence even if on multiple lines). Opinion subject to change.

Comint-based inferior modes often are not evil (eg =intero= and =ESS=). Configure this similarly to term (see below) where C-j/k navigate cmd history and insert mode goes to cmd input line.
