;;; Commentary:
;; This packages provides two commands, `avy-embark-collect-choose' and
;; `avy-embark-collect-act', that use avy to jump to an Embark Collect
;; entry and choose it or act on it, respectively.
;;; Code:
(require 'avy)
(require 'embark)
(eval-when-compile (require 'subr-x))
(defun avy-embark-collect--candidates ()
"Collect all visible Embark collect candidates."
(let (candidates)
(avy-dowindows current-prefix-arg ; avy-dowindows binds wnd! 🤯
(when (derived-mode-p 'embark-collect-mode)
(dolist (pair (avy--find-visible-regions
(window-start) (window-end wnd t)))
(save-excursion
(goto-char (car pair))
(when (button-at (point))
(push (cons (point) wnd) candidates))
(while (and (condition-case nil (forward-button 1)
(error nil))
(< (point) (cdr pair)))
(push (cons (point) wnd) candidates))))))
(nreverse candidates)))
(defun avy-embark-collect--act (pt)
"Act on the completion at PT."
