Add watchers for clojure agent/atom/var/ref reference <2026-02-02 Mon>

I really like the below example from the clojure docs
- ref: https://clojuredocs.org/clojure.core/add-watch#example-549f17c0e4b09260f767ca7f

(def a (atom {}))

(add-watch a :watcher
           (fn [key atom old-state new-state]
             (prn "-- Atom Changed --")
             (prn "key" key)
             (prn "atom" atom)
             (prn "old-state" old-state)
             (prn "new-state" new-state)))

(reset! a {:foo "bar"})

;; "-- Atom Changed --"
;; "key" :watcher
;; "atom" #<Atom@4b020acf: {:foo "bar"}>
;; "old-state" {}
;; "new-state" {:foo "bar"}
;; {:foo "bar"}

Emacs Copy, Cut (Kill), Paste (Yank) Trick

Assume you want to copy or cut part of a paragraph, but not the entire thing.
Go to the start of the text you want to select and press C-space twice.
Then, move to the end of the text you want to operate on and press C-w to cut (kill) or M-w to copy.
This method works in reverse as well, which is quite interesting.
Normally, I select the text I want and then press the copy or cut command, but this approach changes the way you do it completely.

CSS before trick

If you need to add any whitespace before text use the below logic

h2 {
  text-decoration: underline;
}

h2.space::after {
  content: " ";
  white-space: pre;
}
