;; EVIL
;; The `evil' package provides Vim emulation within Emacs, allowing
;; users to edit text in a modal way, similar to how Vim
;; operates. This setup configures `evil-mode' to enhance the editing

;; EVIL COLLECTION

;; EVIL SURROUND
;; The `evil-surround' package provides text object surround
;; functionality for `evil-mode'. This allows for easily adding,
;; changing, or deleting surrounding characters such as parentheses,
;; quotes, and more.
;;
;; With this you can change 'hello there' with ci'" to have
;; "hello there" and cs"<p> to get <p>hello there</p>.
;; More examples here:
;; - https://github.com/emacs-evil/evil-surround?tab=readme-ov-file#examples

;; EVIL MATCHIT
;; The `evil-matchit' package extends `evil-mode' by enabling
;; text object matching for structures such as parentheses, HTML
;; tags, and other paired delimiters. This makes it easier to
;; navigate and manipulate code blocks.
;; Just use % for jumping between matching structures to check it out.
