Elisp: Cut Copy Paste to/from kill-ring
Kill Region to Kill Ring
;; delete text between buffer positions and push to kill-ring (kill-region 247 528)
Note: User's kill-ring content should not change unexpectedly. Emacs lisp function should not use the kill-ring as temp storage of text. If your command is specifically designed to put text to the kill-ring so that user can paste it later, then good. Else, just save text to a variable for your elisp program's use.
(setq x (buffer-substring-no-properties pos1 pos2))
Copy Region to Kill Ring
;; push text between buffer positions to kill-ring (copy-region-as-kill 1 100)
String to Kill Ring
If you already have a string, use
;; push a string into kill-ring (kill-new "cute cat")
Append String to Kill Ring
;; append string to the latest in kill-ring (kill-append "cute cat" nil) ;; if second arg is t, do prepend
Paste from Kill Ring
;; paste from kill-ring (yank)
Mark a Region
To mark a region, do
(push-mark positon). The current cursor positon to positon will become the new region.
To make the region active, use
(setq mark-active t).
(defun my-select-text-in-quote () "Select text between the nearest left and right quotes." (interactive) (let ($pos ($skipChars "^\"")) (skip-chars-backward $skipChars) (setq $pos (point)) (skip-chars-forward $skipChars) (push-mark $pos) (setq mark-active t)))
