eval-after-load使用模式挂钩和使用模式挂钩为东西设置东西之间有区别吗?
我已经看到了在define-key主要模式挂钩中使用的一些代码,以及define-key在eval-after-load表单中使用的其他一些代码。
更新:
为了更好地理解,这是将eval-after-load和mode挂钩与org-mode一起使用的示例。该代码可以运行之前 (load "org")或(require 'org)或(package-initialize)。
;; The following two lines of code set some org-mode options.
;; Usually, these can be outside (eval-after-load ...) and work.
;; In cases that doesn't work, try using setq-default or set-variable
;; and putting them in (eval-after-load ...), if the
;; doc for the variables don't say what to do.
;; Or use Customize interface.
(setq org-hide-leading-stars t)
(setq org-return-follows-link t)
;; "org" because C-h f org-mode RET says that org-mode is defined in org.el
(eval-after-load "org"
'(progn
;; Establishing your own keybindings for org-mode.
;; Variable org-mode-map is available only after org.el or org.elc is loaded.
(define-key org-mode-map (kbd "<C-M-return>") 'org-insert-heading-respect-content)
(define-key org-mode-map (kbd "<M-right>") nil) ; erasing a keybinding.
(define-key org-mode-map (kbd "<M-left>") nil) ; erasing a keybinding.
(defun my-org-mode-hook ()
;; The following two lines of code is run from the mode hook.
;; These are for buffer-specific things.
;; In this setup, you want to enable flyspell-mode
;; and run org-reveal for every org buffer.
(flyspell-mode 1)
(org-reveal))
(add-hook 'org-mode-hook 'my-org-mode-hook)))
eval-after-load进行实际评估nxml-mode,而这个技巧有用!
