(Emacs+Org-Mode) Close Magit-Process Related Buffers When They Become Obselete

My old Magit setup left a bunch of buffers around that I didn’t need anymore. Here is the posted solution to close them automatically:

(defun help/magit-kill-buffers ()
  "Restore window configuration and kill all Magit buffers.
Attribution: URL `https://manuel-uberti.github.io/emacs/2018/02/17/magit-bury-buffer/'"
  (interactive)
  (let ((buffers (magit-mode-get-buffers)))
    (magit-restore-window-configuration)
    (mapc #'kill-buffer buffers)))
(bind-key "q" #'help/magit-kill-buffers magit-status-mode-map)

bash: update_terminal_cwd: command not found resolution

When you run Bash under shell in Emacs on macOS then update_terminal_cwd is never defined and after every command you get the error message bash: update_terminal_cwd: command not found making the shell unusable.

The simplest solution is to define update_terminal_cwd when it isn’t defined.

Here is the code:

if [ -z “$(type -t update_terminal_cwd)” ] || [ “$(type -t update_terminal_cwd)” != “function” ]; then
update_terminal_cwd() {
true
}
fi

(Emacs+Org-Mode) Personal Grammar Reminder Affect vs Effect

I always forget a few grammar rules and can’t seem to get them remembered so I wrote an Elisp snippet to help me remember. Langtool catches this but it isn’t worth waiting. It seems silly to me to write a reminder, but, I bet hundreds of us Emacs users face this. The definition is my own, and includes my opinion about how not to use both words!

(defun affect-vs-effect-explanation ()
  "Definition and example of the most frequent use of Affect vs. Effect."
  (interactive)
  (let* ((title "Affect Versus Effect")
         (sep (make-string (length title) ?=))
         (buf (get-buffer-create (concat "*" title "*"))))
    (switch-to-buffer buf)
    (insert (concat title "\n"))
    (insert (concat sep "\n\n"))
    (insert "Affect is a verb. It means \"to have influence upon\". In the present tense
affect is followed by a noun in the form of \"X affects Y\". For example
\"Choosing between tabs or spaces for indentation affects our happiness.\"
In the past tense it is followed by a preposition before the noun.
For example \"Most people are deeply affected by the their choice between
using tabs or spaces for indentation.\"
Effect is a noun. It is an outcome or result of a verb. For example
\"Choosing spaces for indentation had a positive effect on her happiness.\"
There are other definitions for affect and effect and you probably
shouldn't use them.")
