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

(defun nd/org-todo-position (buffer alist)

                   (window-list)))))
    (when win

        new))))

(defun nd/org-todo-window-advice (orig-fn)
  "Advice to fix window placement in `org-fast-todo-selection'."
  (let  ((override '("\\*Org todo\\*" nd/org-todo-position)))
    (add-to-list 'display-buffer-alist override)

              (delete override display-buffer-alist))))))

(advice-add #'org-fast-todo-selection :around #'nd/org-todo-window-advice)

tag selection

By default, the tag selection window obliterates all but the current window…how disorienting :/

(defun nd/org-tag-window-advice (orig-fn current inherited table &optional todo-table)
  "Advice to fix window placement in `org-fast-tags-selection'."
  (nd/with-advice

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 context; these start with "@"
  • tools: also a GTD context; 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 "_"

NOTE: only these special chars; others make the tag chooser do weird things with the hotkey

(defun nd/add-tag-face (fg-name prefix)
  "Adds list of cons cells to org-tag-faces with foreground set to fg-name.
  Start and end specify the positions in org-tag-alist which define the tags
  to which the faces are applied"

library

Since I am never totally satisfied with how the agenda works, I have a massive library of functions to filter and manipulate tasks (mostly for skip functions). I also have a few variables I set in order to toggle certain views

task helper functions

These are the building blocks for skip functions.

timestamps

Each of these returns the timestamp if found.

(defun nd/get-date-property (date-property)
  "Helper function to get the date property and convert to a number.
If it does not have a date, it will return nil."

									 &optional ref-time future)
  "helper function that returns the timestamp (returned by 
timestamp-fun on the current header) if timestamp is futher back in 
time compared to a ref-time (default to 0 which is now, where negative
is past an positive is future). If the future flag is set, returns 
timestamp if it is in the future compared to ref-time. Returns nil if 
no timestamp is found."
  (let* ((timestamp (funcall timestamp-fun))
        (ref-time (or ref-time 0)))

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.

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.

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.

keybindings

For the sake of my sanity, all bindings go here. Note this means I don't use :bind in use-package forms.

evil

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

base

(use-package evil
  :ensure t
  :init
  ;; this is required to make evil collection work
  (setq evil-want-integration nil)
  :config
  (evil-mode 1))

unbind emacs keys

Some of these commands just get in the way of being evil (which really means that I keep pressing them on accident). Rather than nullifying them completely, tuck them away in the emacs state map in case I actually want them.

(mapc (lambda (k) (nd/move-key global-map evil-emacs-state-map (eval k)))
	  '((kbd "C-s")
		(kbd "C-x C-;")
		(kbd "C-x C-l")
		(kbd "C-x C-u")
		(kbd "C-x C-z")))

evil-org

(use-package evil-org
  :ensure t
  :after (evil org)
  :delight
  :config
  (add-hook 'org-mode-hook 'evil-org-mode)
  (add-hook 'evil-org-mode-hook 'evil-org-set-key-theme)

  (require 'evil-org-agenda)
  (evil-org-agenda-set-keys)
  ;; some of the defaults bug me...
  (evil-define-key 'motion org-agenda-mode-map
	"t" 'nd/toggle-project-toplevel-display
	"D" 'org-agenda-day-view
	"W" 'org-agenda-week-view
	"M" 'org-agenda-month-view
	"Y" 'org-agenda-year-view
	"ct" nil
	"sC" 'nd/org-agenda-filter-non-context
	"e" 'org-agenda-set-effort
	"ce" nil))

evil-magit

(use-package evil-magit
  :ensure t
  :after (evil magit))

visual line mode

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.

(evil-define-key '(normal visual) 'visual-line-mode
  "j" 'evil-next-visual-line
  "k" 'evil-previous-visual-line
  "0" 'beginning-of-visual-line
  "$" 'end-of-visual-line)

ess

ESS has not joined the dark side. Configure similarly to term (see below) where insert mode goes into "char-mode" where we can type like a normal terminal

(add-to-list 'evil-motion-state-modes 'ess-help-mode)
(add-to-list 'evil-insert-state-modes 'inferior-ess-mode)

(defun nd/ess-char-mode-insert ()
  "If not at the last line, go to the end of the buffer and enter insert mode.  Else just enter insert mode."
  (interactive)
  (if (/= (line-number-at-pos (point)) (line-number-at-pos (point-max)))
		(goto-char (point-max))))

(defun nd/inferior-ess-send-input ()
  "Go into insert mode after `inferior-ess-send-input'."
  (interactive)
  (inferior-ess-send-input)
  (evil-insert 1))

(evil-define-key 'normal inferior-ess-mode-map
  (kbd "RET") 'nd/inferior-ess-send-input)

(evil-define-key '(normal insert) inferior-ess-mode-map
  (kbd "C-j") 'comint-previous-input
  (kbd "C-k") 'comint-next-input)

(add-hook 'inferior-ess-mode-hook
		  (lambda ()
			(add-hook 'evil-insert-state-entry-hook
					  'nd/ess-char-mode-insert nil t)))

collection

Most packages that don't have an evil version are in this one. I don't like surprises so I set evil-collection-modes-list with the modes I actually want. Some of these are further configured below.

(use-package evil-collection
  :ensure t
  :after evil
  :init
  (setq evil-collection-modes-list
		'(dired flycheck company which-key helm minibuffer mu4e ediff
				term))
  (setq evil-collection-setup-minibuffer t)
  :config
  (evil-collection-init))
dired

Dired makes new buffers by default. Use find-alternate-file to avoid this.

(put 'dired-find-alternate-file 'disabled nil)

(evil-define-key 'normal dired-mode-map
  "a" 'dired-find-file
  (kbd "<return>") 'dired-find-alternate-file
  "^" (lambda () (interactive) (find-alternate-file ".."))
  (kbd "C-<return>") 'nd/dired-xdg-open)
helm

I like tab completion…regardless of what the helm zealots say. This is actually easier and faster because I can just scroll through the source list with j/k and mash TAB when I find the right directory.

(evil-define-key '(normal insert) helm-map
  (kbd "<tab>") 'helm-execute-persistent-action
  (kbd "C-<tab>") 'helm-select-action)
term

Since I use vi mode in my terminal emulator, need to preserve the escape key's raw behavior

(evil-define-key 'insert term-raw-map
  (kbd "<escape>") (lambda () (interactive) (term-send-raw-string "\e"))
  (kbd "C-<escape>") 'evil-normal-state)

local

These are for mode-specific bindings that can/should be outside of the evil maps above (there are not many, and these may be merged with their evil bretheren in the future)

org-mode

(add-hook 'org-mode-hook
          (lambda ()
