;;; Text objects
|
||
|
||
;; Text objects are defined with `evil-define-text-object'. In Visual
|
||
;; state, they modify the current selection; in Operator-Pending
|
||
;; state, they return a pair of buffer positions. Outer text objects
|
||
;; are bound in the keymap `evil-outer-text-objects-map', and inner
|
||
;; text objects are bound in `evil-inner-text-objects-map'.
|
||
;;
|
||
;; Common text objects like words, WORDS, paragraphs and sentences are
|
||
;; defined via a corresponding move-function. This function must have
|
||
;; the following properties:
|
||
;;
|
||
;; 1. Take exactly one argument, the count.
|
||
;; 2. When the count is positive, move point forward to the first
|
||
;; character after the end of the next count-th object.
|
||
;; 3. When the count is negative, move point backward to the first
|
||
;; character of the count-th previous object.
|
||
;; 4. If point is placed on the first character of an object, the
|
||
;; backward motion does NOT count that object.
|
||
;; 5. If point is placed on the last character of an object, the
|
||
;; forward motion DOES count that object.
|
||
;; 6. The return value is "count left", i.e., in forward direction
|
||
;; count is decreased by one for each successful move and in
|
||
;; backward direction count is increased by one for each
|
||
;; successful move, returning the final value of count.
|
||
;; Therefore, if the complete move is successful, the return
|
||
;; value is 0.
|
||
;;
|
||
;; A useful macro in this regard is `evil-motion-loop', which quits
|
||
;; when point does not move further and returns the count difference.
|
||
;; It also provides a "unit value" of 1 or -1 for use in each
|
||
;; iteration. For example, a hypothetical "foo-bar" move could be
|
||
;; written as such:
|
||
;;
|
||
;; (defun foo-bar (count)
|
||
;; (evil-motion-loop (var count)
|
||
;; (forward-foo var) ; `var' is 1 or -1 depending on COUNT
|
||
;; (forward-bar var)))
|
||
;;
|
||
;; If "forward-foo" and "-bar" didn't accept negative arguments,
|
||
;; we could choose their backward equivalents by inspecting `var':
|
||
;;
|
||
;; (defun foo-bar (count)
|
||
;; (evil-motion-loop (var count)
|
||
;; (cond
|
||
;; ((< var 0)
|
||
;; (backward-foo 1)
|
||
;; (backward-bar 1))
|
||
;; (t
|
||
;; (forward-foo 1)
|
||
;; (forward-bar 1)))))
|
||
;;
|
||
;; After a forward motion, point has to be placed on the first
|
||
;; character after some object, unless no motion was possible at all.
|
||
;; Similarly, after a backward motion, point has to be placed on the
|
||
;; first character of some object. This implies that point should
|
||
;; NEVER be moved to eob or bob, unless an object ends or begins at
|
||
;; eob or bob. (Usually, Emacs motions always move as far as possible.
|
||
;; But we want to use the motion-function to identify certain objects
|
||
;; in the buffer, and thus exact movement to object boundaries is
|
||
;; required.)
