TODO Character equivalence classes

TODO Match newlines with SPC SPC

TODO Leap from window

TODO Only leap to visible targets

Currently, we take care to only search from the point to the beg/end of the window, but we don't account for concealed text, e.g. folded org subtrees.

evil-snipe achieves this by, in their search function, checking if the target is invisible, and skipping the match, if so.

(defun evil-snipe--seek-re (data scope count)
  (let ((regex (mapconcat #'cdr data ""))
        result)
    (when (and evil-snipe-skip-leading-whitespace
               (looking-at-p "[ \t]+")
               (string-match-p "^[ \t]+" (mapconcat #'car data "")))
      (setq regex (concat regex "[^ \t]")))
    (when (setq result (re-search-forward regex scope t count))
      ; ↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓
      (if (or (invisible-p (match-beginning 0))  ; ←
              (invisible-p (1- (match-end 0))))  ; ←
          (evil-snipe--seek-re data scope count) ; ←
      ; ↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑
        result))))

TODO Avoid leaping to target directly under point

Currently, if the point is on a, that very ab pair will be given as a potential target.

TODO Clarify terminology

• "Auto-jump" really means "call evil-leap-action automatically."
• "Jump to target" really means "call evil-leap-action on target."

TODO Comparison with evil-snipe

Weird.
