emacs - 如何在本地模式中取消设置 map 中的键绑定(bind)？

Question

我已经为修改 Emacs 自动完成行为的函数设置了键绑定(bind):

;; 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 only< 中禁用此键绑定(bind)/strong>.

我尝试过以下方法:

;; 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，这不会在本地取消设置键绑定(bind)(即仅在org-mode中)。相反，它会从 ac-menu-map 各处删除按键绑定(bind)。

解决问题的另一种方法是检查 ac-complete-with-space 模式。如果org-mode，则调用self-insert-command，否则遵循您当前的逻辑。
