|
||
* Introduction
|
||
I like having org-mode files look more like a word processor than having it look like programming code. But that is just me.
|
||
* General Org Settings
|
||
Since I use ellipsis in my writing… to /change/ how org renders a collapsed heading.
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(setq org-pretty-entities t
|
||
org-ellipsis "⤵" ; …, ➡, ⚡, ▼, ↴, , ∞, ⬎, ⤷, ⤵
|
||
org-agenda-breadcrumbs-separator " ❱ "
|
||
org-catch-invisible-edits 'show-and-error
|
||
org-special-ctrl-a/e t ; Note: Need to get this working with Evil!
|
||
org-src-fontify-natively t ; Pretty code blocks
|
||
org-hide-emphasis-markers t)
|
||
#+END_SRC
|
||
Oh, and as I indent lists, they should change the /bulleting/ in a particular sequence. If I begin with an =*= asterisk, I walk down the chain, but with the dashed bullets (my default choice), I just stay with dashed bullets. Numeric bullets should cycle:
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(setq org-list-demote-modify-bullet '(("*" . "+") ("+" . "-") ("-" . "-")
|
||
("1." . "a.") ("a." . "1.")))
|
||
#+END_SRC
|
||
|
||
The =org-indent-indentation-per-level=, which defaults to =2= doesn’t really work well with variable-width fonts, so let’s make the spaces at the beginning of the line fixed:
|
||
#+BEGIN_SRC emacs-lisp
|
||
(use-package org
|
||
:config
|
||
(set-face-attribute 'org-indent nil :inherit 'fixed-pitch))
|
||
#+END_SRC
|
||
** Typographic Quotes
|
||
According to [[http://endlessparentheses.com/prettify-your-quotation-marks.html][Artur Malabarba]] of [[http://endlessparentheses.com/prettify-you-apostrophes.html][Endless Parenthesis]] blog, I type a /straight quote/, ", Emacs actually inserts Unicode rounded quotes, like “this”. This idea isn’t how a file is /displayed/, but actually how the file is /made/. Time will tell if this idea works with my auxiliary functions on my phone, like [[https://play.google.com/store/apps/details?id=com.orgzly&hl=en_US&gl=US][Orgzly]] and [[https://github.com/amake/orgro][Orgro]].
|
||
|
||
Stealing his function so that “quotes” just work to insert /rounded/ quotation marks:
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(define-key org-mode-map "\"" #'endless/round-quotes)
|
||
|
||
(defun endless/round-quotes (italicize)
|
||
"Insert “” and leave point in the middle.
|
||
With prefix argument ITALICIZE, insert /“”/ instead
|
||
\(meant for org-mode).
|
||
Inside a code-block, just call `self-insert-command'."
|
||
(interactive "P")
|
||
(if (and (derived-mode-p 'org-mode)
|
||
(org-in-block-p '("src" "latex" "html")))
|
||
(call-interactively #'self-insert-command)
|
||
(if (looking-at "”[/=_\\*]?")
|
||
(goto-char (match-end 0))
|
||
(when italicize
|
||
(if (derived-mode-p 'markdown-mode)
|
||
(insert "__")
|
||
(insert "//"))
|
||
(forward-char -1))
|
||
(insert "“”")
|
||
(forward-char -1))))
|
||
#+END_SRC
|
||
|
||
Stealing function for automatically adding a single quote (not in pairs):
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(define-key org-mode-map "'" #'endless/apostrophe)
|
||
|
||
(defun endless/apostrophe (opening)
|
||
"Insert ’ in prose or `self-insert-command' in code.
|
||
With prefix argument OPENING, insert ‘’ instead and
|
||
leave point in the middle.
|
||
Inside a code-block, just call `self-insert-command'."
|
||
(interactive "P")
|
||
(if (and (derived-mode-p 'org-mode)
|
||
(org-in-block-p '("src" "latex" "html")))
|
||
(call-interactively #'self-insert-command)
|
||
(if (looking-at "['’][=_/\\*]?")
|
||
(goto-char (match-end 0))
|
||
(if (null opening)
|
||
(insert "’")
|
||
(insert "‘’")
|
||
(forward-char -1)))))
|
||
#+END_SRC
|
||
Quote: “From this time forward, I shouldn’t have to worry about quotes.”
|
||
|
||
*Note:* I still need to worry about how quotes affect [[file:ha-org.org::*Spell Checking][spell checking]].
|
||
* Org Beautify
|
||
I really want to use the Org Beautify package, but it overrides my darker themes (and all I really want is headlines to behave).
|
||
|
||
First step is to make all Org header levels to use the variable font, and be the same color as the default text:
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(when window-system
|
||
(let ((default-color (face-attribute 'default :foreground)))
|
||
(dolist (face '(org-level-1 org-level-2 org-level-3 org-level-4 org-level-5 org-level-6 org-level-7 org-level-8))
|
||
(set-face-attribute face nil :height 1.1
|
||
:foreground default-color :weight 'bold :font ha-variable-font))))
|
||
#+END_SRC
|
||
|
||
Next, we just need to change the header sizes:
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(when window-system
|
||
(set-face-attribute 'org-level-1 nil :height 2.2)
|
||
(set-face-attribute 'org-level-2 nil :height 1.8)
|
||
(set-face-attribute 'org-level-3 nil :height 1.4)
|
||
(set-face-attribute 'org-level-4 nil :height 1.2))
|
||
#+END_SRC
|
||
|
||
While we are at it, let’s make sure the code blocks are using my fixed with font:
|
||
#+BEGIN_SRC emacs-lisp
|
||
(when window-system
|
||
(dolist (face '(org-block org-code org-verbatim org-table org-drawer org-table org-formula
|
||
org-special-keyword org-property-value org-document-info-keyword))
|
||
(set-face-attribute face nil :inherit 'fixed-pitch :height 0.9)))
|
||
|
||
(set-face-attribute 'org-table nil :height 1.0)
|
||
(set-face-attribute 'org-formula nil :height 1.0)
|
||
|
||
#+END_SRC
|
||
Not sure why the above code removes the color of =org-verbatim=, so let’s make it stand out slightly:
|
||
#+BEGIN_SRC emacs-lisp
|
||
(set-face-attribute 'org-verbatim nil :foreground "#aaaacc")
|
||
#+END_SRC
|
||
And some slight adjustments to the way blocks are displayed:
|
||
#+BEGIN_SRC emacs-lisp
|
||
(set-face-attribute 'org-block-begin-line nil :background "#282828")
|
||
(set-face-attribute 'org-block nil :height 0.95)
|
||
(set-face-attribute 'org-block-end-line nil :background "#262626")
|
||
#+END_SRC
|
||
And decrease the prominence of the property drawers:
|
||
#+BEGIN_SRC emacs-lisp
|
||
(set-face-attribute 'org-drawer nil :height 0.8)
|
||
(set-face-attribute 'org-property-value nil :height 0.85)
|
||
(set-face-attribute 'org-special-keyword nil :height 0.85)
|
||
#+END_SRC
|
||
This process allows us to use =variable-pitch= mode for all org documents.
|
||
#+BEGIN_SRC emacs-lisp
|
||
(use-package org
|
||
:hook (org-mode . variable-pitch-mode))
|
||
#+END_SRC
|
||
* Superstar
|
||
Now that headers are noticeable, I have no reason to see a number of asterisks. I would think that this would work:
|
||
#+BEGIN_SRC emacs-lisp :tangle no
|
||
(setq org-hide-leading-stars t)
|
||
#+END_SRC
|
||
But since it doesn’t, I need to roll my own. I add a hook to standard Org, and since this is a Lisp-2, I can get away with using the same name as the variable:
|
||
#+BEGIN_SRC emacs-lisp :tangle no
|
||
(defun org-hide-leading-stars ()
|
||
(let* ((keyword
|
||
`(("^\\(\\*+ \\)\\s-*\\S-" ; Do not hide empty headings!
|
||
(1 (put-text-property (match-beginning 1) (match-end 1) 'invisible t)
|
||
nil)))))
|
||
(font-lock-add-keywords nil keyword)))
|
||
|
||
(add-hook 'org-mode-hook 'org-hide-leading-stars)
|
||
#+END_SRC
|
||
|
||
Once I used the [[https://github.com/sabof/org-bullets][org-bullets]] package, but we've replaced it with [[https://github.com/integral-dw/org-superstar-mode][org-superstar-mode]], so the following is an improvement, especially with the sub-bullets:
|
||
#+BEGIN_SRC emacs-lisp
|
||
(use-package org-superstar
|
||
:after org
|
||
:straight (:type git :protocol ssh :host github :repo "integral-dw/org-superstar-mode")
|
||
:hook (org-mode . org-superstar-mode)
|
||
:init
|
||
(setq ; org-superstar-headline-bullets-list '("▶")
|
||
org-superstar-special-todo-items nil
|
||
org-superstar-todo-bullet-alist t
|
||
org-superstar-prettify-item-bullets t
|
||
org-superstar-item-bullet-alist '((42 . "●") ; *
|
||
(43 . "○") ; +
|
||
(45 . "•"))))
|
||
#+END_SRC
|
||
|
||
If this works, then we get the prettier bulleted list:
|
||
* Top bullets
|
||
* Plus bullets:
|
||
+ Apples
|
||
+ Oranges
|
||
+ Bananas
|
||
* Minus bullets:
|
||
- Dogs
|
||
- Cats
|
||
- Birds
|
||
* Checkboxes
|
||
According to an idea by [[https://jft.home.blog/2019/07/17/use-unicode-symbol-to-display-org-mode-checkboxes/][Huy Trần]], (and expanded by the [[https://github.com/minad/org-modern][org-modern]] project), we can prettify the list checkboxes as well:
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(defun ha-org-prettify-checkboxes ()
|
||
"Beautify Org Checkbox Symbol"
|
||
(push '("[ ]" . "☐") prettify-symbols-alist)
|
||
(push '("[X]" . "☐✓") prettify-symbols-alist)
|
||
(push '("[-]" . "☐-") prettify-symbols-alist)
|
||
(prettify-symbols-mode))
|
||
#+END_SRC
|
||
|
||
And now we can attach it to a newly loaded org files:
|
||
#+BEGIN_SRC emacs-lisp
|
||
(add-hook 'org-mode-hook 'ha-org-prettify-checkboxes)
|
||
#+END_SRC
|
||
|
||
To make it more distinguishable, he also changed the colors:
|
||
#+BEGIN_SRC emacs-lisp
|
||
(defface org-checkbox-done-text
|
||
'((t (:foreground "#71696A" :strike-through t)))
|
||
"Face for the text part of a checked org-mode checkbox.")
|
||
|
||
(font-lock-add-keywords
|
||
'org-mode
|
||
`(("^[ \t]*\\(?:[-+*]\\|[0-9]+[).]\\)[ \t]+\\(\\(?:\\[@\\(?:start:\\)?[0-9]+\\][ \t]*\\)?\\[\\(?:X\\|\\([0-9]+\\)/\\2\\)\\][^\n]*\n\\)"
|
||
1 'org-checkbox-done-text prepend))
|
||
'append)
|
||
#+END_SRC
|
||
* SVG-Based Prettiness
|
||
While I'm intrigued with [[https://github.com/rougier][Nicolas P. Rougier]]'s [[https://github.com/rougier/notebook-mode][notebook project]], I really just want to steal their [[https://github.com/rougier/svg-lib][svg-lib project]] that allows me to create and display various SVG objects, namely tags, progress bars, progress pies and icons. Each object fits nicely in a text buffer ensuring width is an integer multiple of character width.

TODO Marks comments for tasks (this can be in source files too).

NOTE: Highlights comments and other notes.

:PROP:tag: are highlighted as two parts of the same tag
|

And :TAG: with colons are highlighted, which include :PROPERTY: drawers.
|

Org-specific #+PROPERTY: entries are highlighted.

#+BEGIN_SRC emacs-lisp :tangle no

#+END_SRC
|
||
* Padding
|
||
The [[https://github.com/TonCherAmi/org-padding][org-padding]] project looks places extra space before and after headers and blocks (essentially leading), to create a more word-processor-y experience. Great idea, however, I have spent a lot of extra time entering blank lines before and after my headers and blocks:
|
||
|
||
#+BEGIN_SRC emacs-lisp
|
||
(use-package org-padding
|
||
:straight (:type git :protocol ssh :host github :repo "TonCherAmi/org-padding")
|
||
:hook
|
||
(org-mode . org-padding-mode)
|
||
:config
|
||
(setq org-padding-block-begin-line-padding '(0.5 . 0.3)
|
||
org-padding-block-end-line-padding '(0.1 . 0.5)
|
||
org-padding-heading-padding-alist
|
||
'((4.0 . 1.5) (3.0 . 0.5) (3.0 . 0.5) (3.0 . 0.5) (2.5 . 0.5) (2.0 . 0.5) (1.5 . 0.5) (0.5 . 0.5))))
|
||
#+END_SRC
|
||
However, I'm just going to have to write a function to clean this.
|
||
#+BEGIN_SRC emacs-lisp :tangle no
|
||
(defun ha-remove-superfluous-org-padding ()
|
||
(interactive)
|
||
(goto-char (point-min))
|
||
(ha-remove-org-header-padding)
|
||
(goto-char (point-min))
|
||
(ha-remove-org-block-padding))
|
||
|
||
(defun ha-remove-org-header-padding ()
|
||
;; (goto-char (point-min))
|
||
(while (re-search-forward (rx (optional bol (zero-or-more space) eol "\n")
|
||
(group bol (one-or-more "*") (one-or-more space) (one-or-more any) "\n")
|
||
(optional bol (zero-or-more space) eol "\n")) nil t)
|
||
(replace-match (match-string 1) nil :no-error)))
|
||
|
||
(defun ha-remove-org-block-padding ()
|
||
;; (goto-char (point-min))
|
||
(while (re-search-forward (rx (optional bol (zero-or-more space) eol "\n")
|
||
(group bol (zero-or-more space) "#+BEGIN" (one-or-more any) eol "\n"
|
||
(zero-or-more (group bol (zero-or-more any) eol "\n"))
|
||
bol (zero-or-more space) "#+END" (zero-or-more any) eol "\n")
|
||
(optional bol (zero-or-more space) eol "\n")) nil t)
|
||
(replace-match (match-string 1) nil :no-error)))
|
||
#+END_SRC
|
||
Now that is some complicated regular expressions.
|
||
* Pasting
|
||
I like the idea that I will paste HTML text from the clipboard and have it converted to org-formatted text:
|
||
#+BEGIN_SRC emacs-lisp
|
||
(defun ha-org-paste ()
|
||
(interactive)
|
||
(if (eq system-type 'gnu/linux)

* Presentations
|
||
Used to use [[https://github.com/takaxp/org-tree-slide][org-tree-slide]] for showing org files as presentations. Converted to use [[https://github.com/rlister/org-present][org-present]]. I love the /hooks/ as that makes it easier to pull out much of my =demo-it= configuration. My concern with =org-present= is that it only jumps from one top-level to another top-level header.
