theme color selection

need this to:

1. apply the gui theme if gui is loaded as client and
2. ensure that the reloaded theme is only applied to the current frame

NOTE: this only works if we start term after gui, and term has light bg. not big deal for now since I hardly ever use term as client

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

todo selection

I only need a teeny tiny window below my current window for todo selection

tags

I use tags for agenda filtering. Very fast and simple. Each tag here starts with a symbol to define its group. Some groups are mutually exclusive, and each group has a different color. Any tag that is not part of these groups (eg some filetags in the few cases I use those) is easy to distinguish as it has the default tag color and is all caps.

There are several types of tags I use:

• location: a GTD contexts; these start with "@"
• tools: also a GTD contexts; these start with "#"
• attribute: useful flags for filtering; these start with "%"
• life areas: key areas of life which define priorities and goals; these start with "_"

(defun nd/add-tag-face (fg-name prefix)

  Start and end specify the positions in org-tag-alist which define the tags

skip functions

These are the primary means we use to sort through tasks. Note that we could do this with tags in the custom commands section but I find this easier to maintain and possibly faster.

atomic tasks

  ;; NOTE: this assumes that tags-todo will
  ;; filter out all done state tasks

periodicals

These are headers marked with PARENT_TYPE=periodical property that have timestamped headers as children which in turn may or may not have todo keywords. They are to be refilled when all children are stale Note that I only care about the parent headers as the children should always show up in the agenda simply because they have timestamps. Parents can be either fresh (at least one child in the future) or stale (all children in the past).

project tasks

Since these are part of projects I need to assess if the parent project is skippable, in which case I jump to the next subtree Note that I only care about the keyword in these cases because I don't archive these, I archive their parent projects. The keywords I care about are NEXT, WAIT, and HOLD because these are definitive project tasks that require/inhibit futher action. (TODO = stuck which I take care of at the project level, and DONE/CANC = archivable which is dealt with similarly)

  (defun nd/skip-non-project-tasks ()
