#+end_src
* Configuration Section
I pretend that my org files are word processing files that wrap automatically:
#+name: visual-hook
#+begin_src emacs-lisp :tangle no
(add-hook 'org-mode-hook #'visual-line-mode)
(add-hook 'before-save-hook 'time-stamp nil)
#+end_src
Files that end in =.txt= are still org files to me:
#+name: text-files
#+begin_src emacs-lisp :tangle no
(add-to-list 'auto-mode-alist '("\\.txt\\'" . org-mode))
(add-to-list 'safe-local-variable-values '(org-content . 2))
#+end_src
*Note:* Org mode files with the =org-content= variable setting will collapse two levels headers. Let's allow that without the need to approve that.
** Better Return
Hitting the ~Return~ key in an org file should format the following line based on context. For instance, at the end of a list, insert a new item.
We begin with the interactive function that calls our code if we are at the end of the line.
#+begin_src emacs-lisp
(defun ha-org-return ()
"If at the end of a line, do something special based on the
information about the line by calling `ha-org-special-return',
otherwise, `org-return' as usual."
(interactive)
(if (eolp)
(ha-org-special-return)
(org-return)))
#+end_src
And bind it to the Return key:
#+name: org-return-key
#+begin_src emacs-lisp :tangle no
(define-key org-mode-map (kbd "RET") #'ha-org-return)
#+end_src
What should we do if we are at the end of a line?
- Given a prefix, call =org-return= as usual in an org file.
- On a link, call =org-return= and open it.
- On a header? Create a new header.
- In a table? Create a new row.
- In a list, create a new item.
I should break this function into smaller bits ...
#+begin_src emacs-lisp
(defun ha-org-special-return (&optional ignore)
"Add new list item with RET.
A double return on an empty element deletes it.
Use a prefix arg to get regular RET."
(interactive "P")
(if ignore
(org-return)
(cond
;; Open links like usual
((eq 'link (car (org-element-context)))
(org-return))
((and (org-really-in-item-p) (not (bolp)))
(if (org-element-property :contents-begin (org-line-element-context))
(progn
(end-of-line)
(org-insert-item))
(delete-region (line-beginning-position) (line-end-position))))
(t
(org-return)))))
#+end_src
How do we know if we are in a list item? Lists end with two blank lines, so we need to make sure we are also not at the beginning of a line to avoid a loop where a new entry gets created with one blank line.
#+begin_src emacs-lisp
(defun org-really-in-item-p ()
"Return item beginning position when in a plain list, nil otherwise.
Unlike `org-in-item-p', this works around an issue where the
point could actually be in some =code= words, but still be on an
item element."
(save-excursion
(let ((location (org-element-property :contents-begin (org-line-element-context))))
(when location
(goto-char location))
(org-in-item-p))))
#+end_src
The org API allows getting the context associated with the /current element/. This could be a line-level symbol, like paragraph or =list-item=, but always when the point isn't /inside/ a bold or italics item. You know how HTML distinguishes between /block/ and /inline/ elements, org doesn't. So, let's make a function that makes that distinction:
#+begin_src emacs-lisp
(defun org-line-element-context ()
"Return the symbol of the current block element, e.g. paragraph or list-item."
(let ((context (org-element-context)))
(while (member (car context) '(verbatim code bold italic underline))
(setq context (org-element-property :parent context)))
context))
#+end_src
** Tasks
I need to add a /blocked/ state, and wouldn’t /doing/ be better than /in progress/ (you know, without a space):
#+name: org-todo
#+begin_src emacs-lisp :tangle no
(setq org-todo-keywords '((sequence "TODO(t)" "DOING(g)" "|" "DONE(d)")
(sequence "BLOCKED(b)" "|" "CANCELLED(c)")))
#+end_src
[[https://janusworx.com/blog/what-i-learned-today-2023-02-10/][Mario Braganza]] had an interesting idea of starting the clock when a task changes to /in progress/:
#+name: org-todo-clock
#+begin_src emacs-lisp
(defun ha-org-clock-todo-change ()
"Called from hook `org-after-todo-state-change-hook'.
Clock in if a task changes to DOING (i.e. IN_PROGRESS),
and clocks out with any other state change."
(if (string= org-state "DOING")
(org-clock-in)
(org-clock-out-if-current)))
(add-hook 'org-after-todo-state-change-hook 'ha-org-clock-todo-change)
#+end_src
And I would like to have cute little icons for those states:
#+name: org-font-lock
#+begin_src emacs-lisp
(dolist (m '(org-mode org-journal-mode))
(font-lock-add-keywords m ; A bit silly but my headers are now
`(("^\\*+ \\(TODO\\) " ; shorter, and that is nice canceled
(1 (progn (compose-region (match-beginning 1) (match-end 1) "⚑") nil)))
("^\\*+ \\(DOING\\) "
(1 (progn (compose-region (match-beginning 1) (match-end 1) "⚐") nil)))
("^\\*+ \\(CANCELED\\) "
(1 (progn (compose-region (match-beginning 1) (match-end 1) "✘") nil)))
("^\\*+ \\(BLOCKED\\) "
(1 (progn (compose-region (match-beginning 1) (match-end 1) "✋") nil)))
("^\\*+ \\(DONE\\) "
(1 (progn (compose-region (match-beginning 1) (match-end 1) "✔") nil)))
;; Here is my approach for making the initial asterisks for listing items and
;; whatnot, appear as Unicode bullets ;; (without actually affecting the text
;; file or the behavior).
("^ +\\([-*]\\) "
(0 (prog1 () (compose-region (match-beginning 1) (match-end 1) "•")))))))
#+end_src
** Meetings
I've notice that while showing a screen while taking meeting notes, I don't always like showing other windows, so I created this function to remove distractions during a meeting.
#+begin_src emacs-lisp
(defun meeting-notes ()
"Call this after creating an org-mode heading for where the notes for the meeting
should be. After calling this function, call 'meeting-done' to reset the environment."
(interactive)
(outline-mark-subtree) ; Select org-mode section
(narrow-to-region (region-beginning) (region-end)) ; Show that region
(deactivate-mark)
(delete-other-windows) ; remove other windows
(text-scale-set 2) ; readable by others
(fringe-mode 0)
(message "When finished taking your notes, run meeting-done."))
#+end_src
Of course, I need an 'undo' feature when the meeting is over…
#+begin_src emacs-lisp
(defun meeting-done ()
"Attempt to 'undo' the effects of taking meeting notes."
(interactive)
(widen) ; Opposite of narrow-to-region
(text-scale-set 0) ; Reset the font size increase
(fringe-mode 1)
(winner-undo)) ; Put the windows back in place
#+end_src
** Searching
Came up with a great way to search a project for Org-specific files, and wrote [[https://howardism.org/Technical/Emacs/org-find-file.html][an essay]] describing the approach and the code. The idea is that I can call =find-file=, but the list of files is not only the filename, but the Org =#+title:= as well as any tags located in the file.
#+begin_src emacs-lisp
(use-package org-find-file
:straight nil
:config
(ha-leader "f o" '("load org" . org-find-file)))
#+end_src
Now that my paragraphs in an org file are on a single line, I could use =rg= (or some other =grep= program), but being able to use an /indexed search system/, like [[https://ss64.com/osx/mdfind.html][mdfind]] on Macos, or [[https://www.lesbonscomptes.com/recoll/][recoll]] on Linux, gives better results than line-oriented search systems. Let’s create operating-system functions the command line for searching:
#+begin_src emacs-lisp
(defun ha-search-notes--macos (phrase path)
"Return the indexed search system command on MACOS, mdfind.
Including the parameters using the PHRASE on the PATH(s)."
(let ((paths (if (listp path)
(mapconcat (lambda (p) (concat "-onlyin " p)) path " ")
(concat "-onlyin " path))))
(format "mdfind %s -interpret %s" paths phrase)))
(defun ha-search-notes--linux (phrase path)
"Return the indexed search system command on Linux, recoll.
Including the parameters using the PHRASE on the PATH(s)."
(format "recoll -t -a -b %s" phrase))
#+end_src
And let’s see how that works:
#+begin_src emacs-lisp :tangle no :results replace
(ha-search-notes--macos "crossway stream" "~/Notes")
#+end_src
This function calls the above-mentioned operating-system-specific functions, but returns the matching files as a /single string/ (where single quotes wrap each file, and all joined together, separated by spaces). This function also allows me to /not-match/ backup files and whatnot.
#+begin_src emacs-lisp
(defun ha-search-notes--files (phrase path)
"Return an escaped string of all files matching PHRASE.
On a Mac, the PATH limits the scope of the search."
(let ((command (if (ha-running-on-macos?)
(ha-search-notes--macos phrase path)
(ha-search-notes--linux phrase path))))
(->> command
(shell-command-to-list)
(--remove (s-matches? "~$" it))
(--remove (s-matches? "#" it))
(--map (format "'%s'" it))
(s-join " "))))
#+end_src
Let’s see it in action:
#+begin_src emacs-lisp :tangle no :results replace
(ha-search-notes--files "openstack grafana" '("~/Notes"))
#+end_src
Returns this string:
#+begin_example
"'/Users/howard.abrams/Notes/Sprint-2022-25.org' '/Users/howard.abrams/Notes/Sprint-2022-03.org' '/Users/howard.abrams/Notes/Sprint-2020-45.org' '/Users/howard.abrams/Notes/Sprint-2022-09.org' '/Users/howard.abrams/Notes/Sprint-2022-05.org' '/Users/howard.abrams/Notes/Sprint-2022-01.org' '/Users/howard.abrams/Notes/Sprint-2022-19.org'"
#+end_example
The =ha-search-notes= function prompts for the phrase to search, and then searches through the =org-directory= path, acquiring matching files, to feed to =grep= (and the [[help:grep][grep function]]) to display a list of matches that I can jump to.
#+begin_src emacs-lisp
(defun ha-search-notes (phrase &optional path)
"Search files in PATH for PHRASE and display in a grep mode buffer."
(interactive "sSearch notes for: ")
(let* ((command (if (ha-running-on-macos?) "ggrep" "grep"))
(regexp (string-replace " " "\\|" phrase))
(use-paths (or path (list org-directory org-journal-dir)))
(files (ha-search-notes--files phrase use-paths))
(cmd-line (format "%s -ni -m 1 '%s' %s" command regexp files)))
(grep cmd-line)))
#+end_src
Add a keybinding to the function:
#+begin_src emacs-lisp
(ha-leader "f n" '("find notes" . ha-search-notes))
#+end_src
** Misc
*** Babel Blocks
I use [[https://orgmode.org/worg/org-contrib/babel/intro.html][org-babel]] (obviously) and don’t need confirmation before evaluating a block:
#+name: ob-configuration
#+begin_src emacs-lisp :tangle no
(setq org-confirm-babel-evaluate nil
org-src-fontify-natively t
org-src-tab-acts-natively t
org-src-window-setup 'current-window)
#+end_src
Whenever I edit Emacs Lisp blocks from my tangle-able configuration files, I get a lot of superfluous warnings. Let's turn them off.
#+name: no-flycheck-in-org
#+begin_src emacs-lisp :tangle no
(defun disable-flycheck-in-org-src-block ()
(setq-local flycheck-disabled-checkers '(emacs-lisp-checkdoc)))
(add-hook 'org-src-mode-hook 'disable-flycheck-in-org-src-block)
#+end_src
And turn on ALL the languages:
#+name: ob-languages
#+begin_src emacs-lisp :tangle no
(org-babel-do-load-languages 'org-babel-load-languages
'((shell . t)
(js . t)
(emacs-lisp . t)
(clojure . t)
(python . t)
(ruby . t)
(dot . t)
(css . t)
(plantuml . t)))
#+end_src
The [[https://github.com/isamert/corg.el][corg project]] does completing feature for all the block header values. To do this, type ~M-Tab~ (not just regular ~Tab~).
#+begin_src emacs-lisp :results list :hlines yes
(use-package corg
:straight (:host github :repo "isamert/corg.el")
:hook (org-mode . 'corg-setup))
#+end_src
*** Searching Literate Files
A noweb definition, e.g. =<<something-something>>= could /jump/ to the =#name= definition.
Since [[https://github.com/BurntSushi/ripgrep][ripgrep]] is pretty fast, I’ll call it instead of attempting to build a [[https://stackoverflow.com/questions/41933837/understanding-the-ctags-file-format][CTAGS]] table. Oooh, the =rg= takes a =—json= option, which makes it easier to parse.
#+begin_src emacs-lisp :noweb no
(defun ha-org-noweb-block-jump (str pos)
"Go to a literate org file containing a symbol, STR.
The POS is ignored."
;; Sometimes I wrap a function name in `=' characters, and these should be removed:
(when (string-match (rx "<<" (group (one-or-more any)) ">>") str)
(setq str (match-string 1 str)))
(ignore-errors
(let* ((default-directory (project-root (project-current)))
(command (format "rg --ignore-case --json '#\\+name: +%s' *.org" str))
(results (thread-last command
shell-command-to-list
second
json-parse-string))
(file (thread-last results
(gethash "data")
(gethash "path")
(gethash "text")))
(line (thread-last results
(gethash "data")
(gethash "line_number"))))
(find-file file)
(goto-line line))))
(when (fboundp 'evil-goto-definition-functions)
(add-to-list 'evil-goto-definition-functions 'ha-org-noweb-block-jump))
#+end_src
*** REST Web Services
Emacs has two ways to query and investigate REST-oriented web services. The [[https://github.com/zweifisch/ob-http][ob-http]] adds HTTP calls to standard org blocks.
#+begin_src emacs-lisp
(use-package ob-http
:init
(add-to-list 'org-babel-load-languages '(http . t)))
#+end_src
And let’s see how it works:
#+begin_src http :pretty :results value replace :wrap src js :var user-agent="my-super-agent"
GET https://api.github.com/repos/zweifisch/ob-http/languages
Accept: application/json
User-Agent: ${user-agent}
#+end_src
#+results:
#+begin_src js
{
"Emacs Lisp": 15327,
"Shell": 139
}
#+end_src
Another approach is [[https://github.com/alf/ob-restclient.el][ob-restclient]], that may be based on the [[https://github.com/pashky/restclient.el][restclient]] project.
#+begin_src emacs-lisp
(use-package ob-restclient
:init
(add-to-list 'org-babel-load-languages '(restclient . t)))
#+end_src
And let’s try this:
#+begin_src restclient :results value replace :wrap src js :var user-agent="my-super-agent"
GET https://api.github.com/repos/zweifisch/ob-http/languages
Accept: application/vnd.github.moondragon+json
User-Agent: ${user-agent}
#+end_src
#+results:
#+begin_src js
{
"Emacs Lisp": 15327,
"Shell": 139
}
#+end_src
*** Graphviz
The [[https://graphviz.org/][graphviz project]] can be written in org blocks, and then rendered as an image:
#+name: ob-graphviz
#+begin_src emacs-lisp :tangle no
(add-to-list 'org-src-lang-modes '("dot" . "graphviz-dot"))
#+end_src
For example:
#+begin_src dot :file support/ha-org-graphviz-example.png :exports file :results replace file
digraph G {
graph [bgcolor=transparent];
edge [color=white];
node[style=filled];
A -> B -> E;
A -> D;
A -> C;
E -> F;
E -> H
D -> F;
A -> H;
E -> G;
}
#+end_src
#+attr_org: :width 400px
#+results:
[[file:support/ha-org-graphviz-example.png]]
*** PlantUML
Need to install and configure Emacs to work with [[https://plantuml.com/][PlantUML]]. Granted, this is easier now that [[http://orgmode.org/worg/org-contrib/babel][Org-Babel]] natively supports [[http://eschulte.github.io/babel-dev/DONE-integrate-plantuml-support.html][blocks of plantuml code]]. First, [[https://plantuml.com/download][download the Jar]].
#+begin_src sh
curl -o ~/bin/plantuml.jar https://github.com/plantuml/plantuml/releases/download/v1.2022.4/plantuml-1.2022.4.jar
#+end_src
After installing the [[https://github.com/skuro/plantuml-mode][plantuml-mode]], we need to reference the location:
#+begin_src emacs-lisp
(use-package plantuml-mode
:straight (:host github :repo "skuro/plantuml-mode")
:init
(setq org-plantuml-jar-path (expand-file-name "~/bin/plantuml.jar")))
#+end_src
With some [[file:snippets/org-mode/plantuml][YASnippets]], I have =<p= to start a general diagram, and afterwards (while still in the org-mode file), type one of the following to expand as an example:
- =activity= :: https://plantuml.com/activity-diagram-betastart
- =component= :: https://plantuml.com/component-diagram
- =deployment= :: https://plantuml.com/deployment-diagram
- =object= :: https://plantuml.com/object-diagram
- =sequence= :: https://plantuml.com/sequence-diagram
- =state= :: https://plantuml.com/state-diagram
- =timing= :: https://plantuml.com/timing-diagram
- =use-case= :: https://plantuml.com/use-case-diagram
You may be wondering how such trivial terms can be used as expansions in an org file. Well, the trick is that each snippets has a =condition= that calls the following predicate function, that make the snippets context aware:
#+begin_src emacs-lisp
(defun ha-org-nested-in-plantuml-block ()
"Predicate is true if point is inside a Plantuml Source code block in org-mode."
(equal "plantuml"
(plist-get (cadr (org-element-at-point)) :language)))
#+end_src
Here is a sequence diagram example to show how is looks/works:
#+begin_src plantuml :file ha-org-plantuml-example.png :exports file :results file
@startuml
!include https://raw.githubusercontent.com/ptrkcsk/one-dark-plantuml-theme/v1.0.0/theme.puml
' See details at https://plantuml.com/sequence-diagram
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response
Alice -> Bob: Another authentication Request
Alice <-- Bob: Another authentication Response
@enduml
#+end_src
#+attr_org: :width 800px
[[file:ha-org-plantuml-example.png]]
*** Pikchr
No, not Pikachu, but close. The [[https://pikchr.org/home/doc/trunk/homepage.md][Pikchr project]] is similar to Graphviz and Plantuml, but makes the boxes more positional and really allows one to place things more precisely. Yet another steep learning curve.
Not sure if anyone has made a /package/, so we need to download and build locally:
#+begin_src sh :dir ~/bin
curl -o ~/bin/pikchr.c https://pikchr.org/home/raw/9aac00a46506e993db45b740f7a7957f8f381b37001e196199dfc25642c44f06?at=pikchr.c
# gcc -c pikchr.c # to build the Pikchr library
gcc -DPIKCHR_SHELL -o ~/bin/pikchr ~/bin/pikchr.c -lm # to build the pikchr command-line tool
#+end_src
Of course, since we are dealing with Emacs, any good idea will be assimilated. Johann Klähn created [[https://github.com/kljohann/pikchr-mode][pikchr-mode]]:
#+begin_src emacs-lisp
(use-package pikchr-mode
:straight (:local-repo "~/src/pikchr-mode")
:custom
(pikchr-executable "~/bin/pikchr"))
#+end_src
Let’s see this in action:
#+begin_src pikchr :file ha-org-pikchr-01.svg :results file :exports both
bgcolor = 0x1d2021
fgcolor = 0xeeeeee
line; box "Hello," "World!"; arrow
#+end_src
Results in:
#+ATTR_HTML: :width 300 :style font-family:Sans,Arial
[[file:ha-org-pikchr-01.svg]]
And this example shows off the syntax colorization:
#+begin_src pikchr :file ha-org-pikchr-02.svg :results file :exports both
A: box "head" fit
B: box "tail" fit
C: box "something" with .sw at A.nw fit wid dist(A.w, B.e)
#+end_src
For the results:
#+ATTR_HTML: :width 300 :background white
[[file:ha-org-pikchr-02.svg]]
*** Mermaid
At work, I’ve been integrating [[https://mermaidjs.github.io/][Mermaid]] into our documentation, =foobar=.
Assuming we have installed the [[https://github.com/mermaid-js/mermaid-cli][Mermaid CLI]]:
#+BEGIN_SRC sh
npm install -g @mermaid-js/mermaid-cli
#+END_SRC
We edit the code with [[https://github.com/abrochard/mermaid-mode][mermaid-mode]]:
#+BEGIN_SRC emacs-lisp
(use-package mermaid-mode
:config
(setq mermaid-mmdc-location "/opt/homebrew/bin/mmdc"))
#+END_SRC
We can make Mermaid diagrams in Emacs Org files using [[https://github.com/arnm/ob-mermaid][ob-mermaid]]:
#+BEGIN_SRC emacs-lisp

*** Next Image
When I create images or other artifacts that I consider /part/ of the org document, I want to have them based on the org file, but with a prepended number. Keeping track of what numbers are now free is difficult, so for a /default/ let's figure it out:
#+begin_src emacs-lisp
(defun ha-org-next-image-number (&optional prefix)
(when (null prefix)
(if (null (buffer-file-name))
(setq prefix "cool-image")
(setq prefix (file-name-base (buffer-file-name)))))
(save-excursion
(goto-char (point-min))
(let ((largest 0)
(png-reg (rx (literal prefix) "-" (group (one-or-more digit)) (or ".png" ".svg"))))
(while (re-search-forward png-reg nil t)
(setq largest (max largest (string-to-number (match-string-no-properties 1)))))
(format "%s-%02d" prefix (1+ largest)))))

* Supporting Packages
** Exporters
Limit the number of exporters to the ones that I would use:
#+name: ox-exporters
#+begin_src emacs-lisp
(setq org-export-backends '(ascii html md texinfo odt))
#+end_src
I have a special version of tweaked [[file:elisp/ox-confluence.el][Confluence exporter]] for my org files:
#+begin_src emacs-lisp
(use-package ox-confluence
:after org
:straight nil ; Located in my "elisp" directory
:config
(ha-leader :keymaps 'org-mode-map
"o E" '("to confluence" . ox-export-to-confluence)))
#+end_src
And Graphviz configuration using [[https://github.com/ppareit/graphviz-dot-mode][graphviz-dot-mode]]:
#+begin_src emacs-lisp
(use-package graphviz-dot-mode
:mode "\\.dot\\'"
:init
(setq tab-width 4
graphviz-dot-indent-width 2
graphviz-dot-auto-indent-on-newline t
graphviz-dot-auto-indent-on-braces t
graphviz-dot-auto-indent-on-semi t))
#+end_src
*** HTML Style
I’m not afraid of HTML, but I like the idea of doing my HTML work in a Lisp-like way using the [[https://github.com/tonyaldon/jack][jack-html project]]:
#+begin_src emacs-lisp
(use-package jack
:straight (:host github :repo "tonyaldon/jack")
:commands (jack-html))
#+end_src
So the Lisp code:
#+begin_src emacs-lisp :tangle no
(jack-html '(:p "Hello there"))
#+end_src
Returns the string:
#+begin_example
<p>Hello there</p>
#+end_example
Splitting out HTML snippets is often a way that I can transfer org-formatted content to other applications.
#+name: html-exporting
#+begin_src emacs-lisp
(use-package jack
:after org
:config
(setq org-html-head-extra
(jack-html `((:link (@ :rel "stylesheet"

:LOGBOOK:

I've been working on my own [[http://www.howardism.org/Technical/Emacs/focused-work.html][approach to focused work]],
#+begin_src emacs-lisp

:straight (:type built-in)

(ha-leader

#+end_src
** Spell Checking
Let's hook some spell-checking into org files, and actually all text files. I’m making this particularly delicious.
*** abbrev
First, we turn on =abbrev-mode=. While this package comes with Emacs, check out [[https://masteringemacs.org/article/correcting-typos-misspellings-abbrev][Mickey Petersen's overview]] of using this package for auto-correcting typos.
#+begin_src emacs-lisp
(setq-default abbrev-mode t)
#+end_src
In general, /fill/ the list, by moving the point to the /end/ of some word, and type ~C-x a g~ (or, in /normal state/, type ~SPC x d~):
#+begin_src emacs-lisp
(ha-leader "x d" '("add abbrev" . kadd-global-abbrev))
#+end_src
The idea is that you can correct a typo /and remember/ it. Perhaps calling [[help:edit-abbrevs][edit-abbrevs]] to making any fixes to that list.
*** jinx
Once upon a time, I used [[https://www.emacswiki.org/emacs/FlySpell][flyspell]] mode to highlight the misspelled words, and the venerable [[https://www.emacswiki.org/emacs/InteractiveSpell][ispell]] for correcting. To be able to correct spelling mistakes /from a distance/, without navigation, I wrote a function that took advantage of Evil’s [[help:evil-prev-flyspell-error][evil-prev-flyspell-error]] to jump back to the last spelling mistake.
Now, I’m using [[https://github.com/minad/jinx][jinx]], as it is the /complete basket/. It spellchecks based on the fontlock face and uses an external [[https://github.com/AbiWord/enchant][enchant program]] (to make spell-checking fast and asynchronous). Like =flymake=, Jinx does on-the-fly spellchecking of code comments and strings.
I keep =jinx-correct= bound to ~C-;~ à la flyspell because it is so darn helpful. Supports checking documents with mixed languages.
Requires the =libenchant= from the [[https://abiword.github.io/enchant/][Enchant project]], so on MacOS, I install it via:
#+begin_src sh
brew install enchant
#+end_src
And on Linux:
#+begin_src sh
sudo apt install libenchant-2-dev
#+end_src
And the Emacs interface to that:
#+begin_src emacs-lisp
(use-package jinx
:hook (emacs-startup . global-jinx-mode)
:bind (("M-$" . jinx-correct-nearest)
("s-;" . jinx-correct-nearest))
:general
(:states '(normal insert) :keymaps 'text-mode-map
"M-s M-s" 'jinx-correct)
:config
(ha-leader
"s i" '("spellcheck buffer" . jinx-correct-all)
"S b" '("spellcheck buffer" . jinx-correct-all)))
#+end_src
Jinx works really good, as the mini-buffer allows you to use letters to filter the choice, and numbers (or Return) to select the choice. Selecting ~@~ adds the word to your personal dictionary, and ~*~ adds it to the /local words/ for the file (search for =jinx-local-words=). Also, it appears that calling =jinx-correct= goes back to the first incorrect spelling, letting you correct it, and then pops the point back. That is pretty slick.
It also, supposedly, fixes =camelCase= words. This doesn’t work in a text document. I appreciate that in org-mode files, text surrounded with = characters are no longer marked for misspellings.
Since this auto-correction needs to happen in /insert/ mode, I have bound a few keys, including ~CMD-s~ and ~M-s~ (twice) to fixing this spelling mistake, and jumping back to where I am.
*** Thesaurus
Of course I need a thesaurus, and I'm installing [[https://github.com/SavchenkoValeriy/emacs-powerthesaurus][powerthesaurus]]:
#+begin_src emacs-lisp
(use-package powerthesaurus
;; :bind ("s-t" . powerthesaurus-lookup-dwim)
:config
(ha-leader
"S t" '("thesaurus" . powerthesaurus-lookup-dwim)
"S s" '("synonyms" . powerthesaurus-lookup-synonyms-dwim)
"S a" '("antonyms" . powerthesaurus-lookup-antonyms-dwim)
"S r" '("related" . powerthesaurus-lookup-related-dwim)
"S S" '("sentence" . powerthesaurus-lookup-sentences-dwim)))
#+end_src
The key-bindings, keystrokes, and key-connections work well with ~M-T~ (notice the Shift), but to jump to specifics, we use a leader.
*** Definitions
Since the /definitions/ do not work, so let's use the [[https://github.com/abo-abo/define-word][define-word]] project:
#+begin_src emacs-lisp
(use-package define-word
;; :bind ("s-d" . define-word-at-point)
:config
(ha-leader :keymaps 'text-mode-map
"S D" '("define word" . define-word)))
#+end_src
After my enamoring of Noah Webster’s 1913 dictionary (originally due to reading [[https://janusworx.com/blog/thank-god-for-noah/][this essay]] by Mario Jason Braganza who referred to James Somers’ original [[https://jsomers.net/blog/dictionary][2014 blog entry]]), I easily followed the instructions from [[https://github.com/ponychicken/WebsterParser][WebsterParser]], a Github project, with the dictionary:
1. Download [[https://github.com/ponychicken/WebsterParser/releases/latest/download/websters-1913.dictionary.zip][the dictionary]] file.
2. Unzip the archive … have a *Finder* window open to the =.dictionary= file.
3. Open the =Dictionary.app= program.
4. Select the menu entry, *Dictionary –> File –> Open Dictionaries Folder*
5. Drag the downloaded =Websters-1913.dictionary= file into the folder
6. Select the menu entry, *Dictionary –> Dictionary –> Preferences*
7. Check the now last dictionary in the list
If you want to always see Webster’s results by default, go to the Dictionary app’s preferences and drag Webster’s to the top of the list.
Now that I’m mostly on version 28 and above of Emacs, we can take advantage of [[help:dictionary-search][dictionary-search]] for looking up dictionaries online, and out of all the word definitions packages for Emacs, this looks the best and is easiest to read:
#+begin_src emacs-lisp
(setq dictionary-server "dict.org")
(ha-leader "S d" '("define this" . dictionary-search))
#+end_src
Once in the dictionary buffer, acquiesce these keybindings:
- ~q~ close the dictionary buffer
- ~s~ ask for a new word to search
- ~d~ search the word at point
Also note that the dictionary has links to other pages, so ~n~ and ~TAB~ jumps to the next link and ~RET~ opens that link.
** Grammar and Prose Linting
Flagging cliches, weak phrasing and other poor grammar choices.
We are trying a lot of checkers, so we need to /chain/ them with a call to =flycheck-add-next-checker=:
=write-good= —> =proselint= —> =textlint= —> =languagetool=?
*** Writegood
The [[https://github.com/bnbeckwith/writegood-mode][writegood-mode]] is effective at highlighting passive and weasel words.
#+begin_src emacs-lisp
(use-package writegood-mode)
#+end_src
And it reports obnoxious messages.
Hrm::hook ((org-mode . writegood-mode)
(gfm-mode . writegood-mode)
(markdown-mode) . writegood-mode)
We install the =write-good= NPM:
#+begin_src shell
npm install -g write-good
#+end_src
And check that the following works:
#+begin_src sh :results output
write-good --text="So it is what it is."
#+end_src
Now, let’s connect it to flycheck:
#+begin_src emacs-lisp
(use-package flycheck
:config
(flycheck-define-checker write-good
"A checker for prose"
:command ("write-good" "--parse" source-inplace)
:standard-input nil
:error-patterns
((warning line-start (file-name) ":" line ":" column ":" (message) line-end))
:modes (markdown-mode org-mode text-mode))
(add-to-list 'flycheck-checkers 'write-good))
#+end_src
*** Proselint
With overlapping goals to =write-good=, the [[https://github.com/amperser/proselint/][proselint]] project, once installed, can check for some English phrasings. I like =write-good= better, but I want this available for its level of /pedantic-ness/.
#+begin_src sh
brew install proselint
#+end_src
And on Linux:
#+BEGIN_SRC sh
sudo apt install python3-proselint
#+END_SRC
Next, create a configuration file, =~/.config/proselint/config= file, to turn on/off checks:
#+begin_src js :tangle ~/.config/proselint/config.json :mkdirp yes
{
"checks": {
"typography.diacritical_marks": false,
"annotations.misc": false,
"consistency.spacing": false
}
}
#+end_src
And tell [[https://www.flycheck.org/][flycheck]] to use this:
#+begin_src emacs-lisp
(use-package flycheck
:config
(add-to-list 'flycheck-checkers 'proselint)
;; And create the chain of checkers so that both work:
(flycheck-add-next-checker 'write-good 'proselint))
#+end_src
*** Textlint
The [[https://textlint.github.io/][textlint]] project comes with =flycheck=, as long as there is an executable:
#+begin_src sh :results silent
sudo npm install -g textlint
# And all the rules
sudo npm install -g textlint-rule-alex
sudo npm install -g textlint-rule-diacritics
sudo npm install -g textlint-rule-en-max-word-count
sudo npm install -g textlint-rule-max-comma
sudo npm install -g textlint-rule-no-start-duplicated-conjunction
sudo npm install -g textlint-rule-period-in-list-item
sudo npm install -g textlint-rule-stop-words
sudo npm install -g textlint-rule-terminology
sudo npm install -g textlint-rule-unexpanded-acronym
#+end_src
I create a configuration file in my home directory:
#+begin_src js :tangle ~/.textlintrc
{
"filters": {},
"rules": {
"abbr-within-parentheses": false,
"alex": true,
"common-misspellings": false,
"diacritics": true,
"en-max-word-count": true,
"max-comma": true,
"no-start-duplicated-conjunction": true,
"period-in-list-item": true,
"stop-words": true,
"terminology": true,
"unexpanded-acronym": true,
"write-good": false
}
}
#+end_src
Add =textlint= to the /chain/ for Org files:
#+begin_src emacs-lisp
(use-package flycheck
:config
(setq flycheck-textlint-config (format "%s/.textlintrc" (getenv "HOME")))
(flycheck-add-next-checker 'proselint 'textlint t))
#+end_src
*** Language Tool
Another flycheck feature is to use [[http://languagetool.org][LanguageTool]] connection to [[https://github.com/emacs-languagetool/flycheck-languagetool][flycheck-languagetool]]:
#+BEGIN_SRC emacs-lisp :tangle no
(use-package flycheck-languagetool
:ensure t
:hook (text-mode . flycheck-languagetool-setup)
:init
(setq flycheck-languagetool-server-jar (expand-file-name "~/other/LanguageTool/languagetool-server.jar")
flycheck-languagetool-server-args (expand-file-name "~/.config/languagetool/config.properties")))
#+END_SRC
And connect it to the chain:
#+BEGIN_SRC emacs-lisp :tangle no
(use-package flycheck
:config (flycheck-add-next-checker 'textlint 'languagetool t)
;; May have to specify a Java on one of my Mac machines:
(when (file-exists-p "/opt/homebrew/opt/openjdk")
(add-to-list 'exec-path "/opt/homebrew/opt/openjdk/bin")))
#+END_SRC
This check complains about whitespace in Org files (duh), so let’s create a configuration file where we can disable that rule (and any other we can require):
#+BEGIN_SRC conf :tangle ~/.config/languagetool/config.properties :mkdirp ~/.config/languagetool
disabledRuleIds: WHITESPACE
#+END_SRC
Gotta admit that Language Tool doesn’t seem to help much. $ 100 ?
** Perfect Sentence
Chris Malorana’s [[https://www.youtube.com/watch?v=E-yk_V5TnNU][video tutorial]] demonstrates the ability to extrude a single sentence into another buffer, edit different versions of that sentence, and replace one version into the original buffer. For instance, how org-mode edits blocks.
Malorana based this idea on Jordan Peterson's writing app, [[https://essay.app/guide][Essay]]. Thought I might work on it, but I want my version more resilient and not as dependent on the context.
When we create a new buffer, we set the following /buffer-local/ variables, so we know where to return:
#+begin_src emacs-lisp
(defvar-local ha-sentence-buffer nil
"The name of the buffer to return when completed.")
(defvar-local ha-sentence-begin nil
"The beginning position in the original buffer to replace text.")
(defvar-local ha-sentence-end nil
"The ending position in the original buffer to replace text.")
#+end_src
My first thought is how to select the sentence. Sure, sometimes that should be the /region/, but we can also use the help:bounds-of-thing-at-point to define the start and the end of the current sentence:
#+begin_src emacs-lisp
(defun ha-sentence--select-region (type-of-thing &optional start end)
"Return a tuple of the start and end of the selected sentence."
(cond
((region-active-p) (cons (region-beginning) (region-end)))
((and start end) (cons start end))
(t (bounds-of-thing-at-point type-of-thing))))
#+end_src
In the original buffer, we want to edit a /sentence/, but in the editing buffer, a single sentence may expand to more than one, so we need to change whether we select a ='sentence= or a ='defun= (for a paragraph).
With this function, we can call [[help:cl-destructuring-bind][destructuring-bind]] to define what section we want to edit by assigning the =start= and =end= values. Now we create another buffer window, set the local variables, and insert the region/sentence we requested:
#+begin_src emacs-lisp
(defun ha-sentence-break (&optional start end)
"Break a sentence out and work it in a new buffer.
We base the chosen sentence chosen on the location of a point,
or the active region."
(interactive)
(cl-destructuring-bind (start . end)
(ha-sentence--select-region 'sentence start end)
(let ((orig-mode major-mode)
(orig-buffer (current-buffer))
(orig-sentence (buffer-substring-no-properties start end)))
(switch-to-buffer-other-window "**sentence-breakout**")
(funcall orig-mode)
(ha-sentence-buffer-mode)
;; Store some breadcrumbs so we can return where we left off:
(setq-local ha-sentence-buffer orig-buffer
ha-sentence-begin start
ha-sentence-end end)
(erase-buffer)
(insert orig-sentence)
;; Because we might want to duplicate the sentence in the
;; buffer, let's put it on the kill ring:
(kill-new orig-sentence))))
#+end_src
With the new buffer displayed, we show the sentence to edit, with the idea to write different versions of that sentence. When we have the version we like, we hit ~C-c C-c~ which calls [[help:ha-sentence-choose][ha-sentence-choose]] /to choose/ the version that replaces the old one. But what if, during the editing process, we create more than one sentence?
In that case, we need to select the text before hitting the ~C-c C-c~ sequence. The buffer-local variables tell us which buffer to return, and what text to replace.
#+begin_src emacs-lisp
(defun ha-sentence-choose (&optional start end)
"Choose a sentence and go back to the other window."
(interactive)
;; By default, our "region" is a paragraph using 'defun symbol of `thing-at-point'
;; It doesn't work on the last sentence if it doesn't include a
;; newline, so hackily, we insert one.
(save-excursion
(goto-char (point-max))
(insert "\n"))
(cl-destructuring-bind (start . end) (ha-sentence--select-region 'defun start end)
(let ((chosen-sentence (buffer-substring-no-properties start end))
(orig-buffer ha-sentence-buffer)
(orig-start ha-sentence-begin)
(orig-end ha-sentence-end))
(kill-buffer-and-window)
(switch-to-buffer orig-buffer)
(delete-region orig-start orig-end) ; Or call `kill-region' to put on clipboard?
(insert chosen-sentence))))
#+end_src
The [[help:kill-region][kill-region]] function takes the original text and places it on the [[help:kill-ring][kill-ring]] (the clipboard). But since we already copied that when we created the buffer, we call [[help:delete-region][delete-region]] instead. Especially since if we felt like we made a mistake, we could just undo the changes.
With my limited experience, I seldom enter completely difference sentences. Instead, I want to /copy/ the sentence and work on that. Let’s make a function to duplicate it.
#+begin_src emacs-lisp
(defun ha-sentence-duplicate ()
(interactive)

When creating this new editing buffer, we need keybindings that exist only for this buffer, in other words, a [[https://www.gnu.org/software/emacs/manual/html_node/elisp/Defining-Minor-Modes.html][minor mode]]:
#+begin_src emacs-lisp
(defvar ha-sentence-buffer-mode-map (make-sparse-keymap) "Keymap for `my-mode'.")
(define-key ha-sentence-buffer-mode-map (kbd "C-c C-c") #'ha-sentence-choose)
(define-key ha-sentence-buffer-mode-map (kbd "C-c C-k") #'kill-buffer-and-window)
(define-key ha-sentence-buffer-mode-map (kbd "C-c C-d") #'ha-sentence-duplicate)
(define-minor-mode ha-sentence-buffer-mode
"Toggle the Perfect Sentence mode.
Interactively with no argument, this command toggles the mode.
A positive prefix argument enables the mode, any other prefix
argument disables it. From Lisp, argument omitted or nil enables
the mode, `toggle' toggles the state.
When this mode is enabled, `C-c C-c' calls `ha-sentence-choose',
and `C-c C-k' cancels and buries the buffer."

Let’s bind a couple key sequences for Emacs mode:
#+begin_src emacs-lisp
(global-set-key (kbd "M-s b") 'ha-sentence-break)
#+end_src
I am making this global, as it may be nice in both org-mode and programming modes.
And something else while in Evil mode:
#+begin_src emacs-lisp
(ha-leader "x b" '("edit sentence" . ha-sentence-break))
#+end_src
Perhaps he might get around to turning [[https://git.chrismaiorana.com/?p=sentinel.git;a=blob;f=sentin.el;h=2738eff6ac2b0877576bafe88878683a7eff3125;hb=refs/heads/master][his code]] into a package. Features needed include:
- Adding an overlay to the original text, help:org-src--make-source-overlay
** Distraction-Free Writing
[[https://christopherfin.com/writing/emacs-writing.html][Christopher Fin's essay]] inspired me to clean my writing room.
*** Write-room
For a complete focused, /distraction-free/ environment, for writing or concentrating, I'm using [[https://github.com/joostkremers/writeroom-mode][Writeroom-mode]]:
#+begin_src emacs-lisp
(use-package writeroom-mode
:hook (writeroom-mode-disable . winner-undo)
:init
(ha-leader "t W" '("writeroom" . writeroom-mode))
(ha-leader :keymaps 'writeroom-mode-map
"=" '("adjust width" . writeroom-adjust-width)
"<" '("decrease width" . writeroom-decrease-width)
">" '("increase width" . writeroom-increase-width))
:bind (:map writeroom-mode-map
("C-M-<" . writeroom-decrease-width)
("C-M->" . writeroom-increase-width)
("C-M-=" . writeroom-adjust-width)))
#+end_src
*** Olivetti
The [[https://github.com/rnkn/olivetti][olivetti project]] sets wide margins and centers the text. It isn’t better than Writeroom, but, it works well with Logos (below).
#+begin_src emacs-lisp
(use-package olivetti
:init
(setq-default olivetti-body-width 100)
(ha-leader "t O" '("olivetti" . olivetti-mode))
:bind (:map olivetti-mode-map
("C-M-<" . olivetti-shrink)
("C-M->" . olivetti-expand)
("C-M-=" . olivetti-set-width)))
#+end_src
*** Logos
Trying out [[https://protesilaos.com/][Protesilaos Stavrou]]’s [[https://protesilaos.com/emacs/logos][logos project]] as a replacement for [[https://github.com/joostkremers/writeroom-mode][Writeroom-mode]]:
#+begin_src emacs-lisp
(use-package logos
:straight (:host gitlab :repo "protesilaos/logos")
:init
(setq logos-outlines-are-pages t
logos-outline-regexp-alist
`((emacs-lisp-mode . "^;;;+ ")
(org-mode . "^\\*+ +")
(t . ,(or outline-regexp logos--page-delimiter))))
;; These apply when enabling `logos-focus-mode' as buffer-local.
(setq-default logos-hide-mode-line t
logos-scroll-lock nil
logos-indicate-buffer-boundaries nil
logos-buffer-read-only nil
logos-olivetti t)
:config
(ha-leader "t L" '("logos" . logos-focus-mode))
(define-key global-map [remap narrow-to-region] #'logos-narrow-dwim)
:general
(:states 'normal
"g [" '("back page" . logos-backward-page-dwim)
"g ]" '("next page" . logos-forward-page-dwim)))
