Question

我为修改Emacs auto-complete的行为的函数设置了一个键绑定：

;; ISSUE: when I type the whole candidate string and then press [SPC], 
;; Emacs will insert two spaces.
(define-key ac-menu-map (kbd "SPC")
  (defun ac-complete-with-space ()
    "Select the candidate and append a space. Save your time for typing space."
    (interactive)
    (ac-complete)
    ;; FIXME: this auto-inserts two spaces.
    (insert " ")
    ))

...我想在ac-menu-map org-mode 中禁用此键绑定。

我尝试了以下内容：

;; Avoid always selecting unwanted first candidate with auto-complete 
;; when writing in org-mode.
(add-hook 'org-mode-hook
          (lambda ()
            ;; (define-key ac-menu-map (kbd "SPC") nil)
            ;; (define-key ac-menu-map (kbd "SPC") 'self-insert-command)
            ;; (setq-local ac-menu-map (delq (kbd "SPC") ac-menu-map))
            ))

不幸的是，这并没有取消本地键绑定（即仅在org-mode中）。相反，它会从ac-menu-map到处删除密钥绑定。

Answer 1

解决问题的另一种方法是检查ac-complete-with-space模式。如果是org-mode，请致电self-insert-command，否则请按照您当前的逻辑进行操作。

Answer 2

(defun ac-complete-with-space ()
  "Select the candidate and append a space. save your time for typing space."
  (interactive)
  (ac-complete)
  (insert " ")
  )

;; NOTE: ac-completing-map is the parent map of ac-menu-map.
(define-key ac-completing-map (kbd "SPC") 'ac-complete-with-space)
(add-hook 'org-mode-hook
          (lambda ()
            (define-key ac-menu-map (kbd "SPC") 'self-insert-command)))

如何在地图中将地图中的键绑定取消设置为模式？
