emacs配置文件中比较好用的函数

(声明:这些函数非本人原创,是本人从各处收集的,后期还会更新)

1.在当前行之前,之后插入新行(类似与vim在normal模式下的a和o键)

出处(http://whattheemacsd.com/)

;;C-return 在当前行上新开一行;;C-S-return 在当前行下新开一行(defun open-line-below ()  (interactive)  (end-of-line)  (newline)  (indent-for-tab-command))(defun open-line-above ()  (interactive)  (beginning-of-line)  (newline)  (forward-line -1)  (indent-for-tab-command))(global-set-key (kbd "<C-return>") 'open-line-below)(global-set-key (kbd "<C-S-return>") 'open-line-above)

C即ctrl键,S即shift键盘;

使用elisp语言定义了两个函数,open-line-below和open-line-above.

open-line-below是在当前行之下插入新行,open-line-above实在当前行之上插入新行

将这两个函数分别映射到了<C-return>和<C-S-return>两个快捷键上.

2.emacs全屏

(interactive)  (x-send-client-message nil 0 nil "_NET_WM_STATE" 32                         ;; if first parameter is '1', can't toggle fullscreen status                         '(1 "_NET_WM_STATE_FULLSCREEN" 0)))(defun fullscreen-toggle ()  "Toggle fullscreen status."  (interactive)  (x-send-client-message nil 0 nil "_NET_WM_STATE" 32                         ;; if first parameter is '2', can toggle fullscreen status                         '(2 "_NET_WM_STATE_FULLSCREEN" 0)))(provide 'fullscreen);;; fullscreen.el ends here

将上面这段代码复制下来，保存为fullscreen.el,在.emacs中加入fullscreen.el的路径，在.emacs加入以下代码：

(require 'fullscreen)(global-set-key [f11] 'fullscreen-toggle)

绑定到了快捷键F11上，按一次最大化，再按一次又恢复了，很方便

3.重命名当前缓冲区

;;快捷键 C-x C-r重命名当前缓冲区(defun rename-current-buffer-file ()  "Renames current buffer and file it is visiting."  (interactive)  (let ((name (buffer-name))        (filename (buffer-file-name)))    (if (not (and filename (file-exists-p filename)))        (error "Buffer '%s' is not visiting a file!" name)      (let ((new-name (read-file-name "New name: " filename)))        (if (get-buffer new-name)            (error "A buffer named '%s' already exists!" new-name)          (rename-file filename new-name 1)          (rename-buffer new-name)          (set-visited-file-name new-name)          (set-buffer-modified-p nil)          (message "File '%s' successfully renamed to '%s'"                   name (file-name-nondirectory new-name)))))))(global-set-key (kbd "C-x C-r") 'rename-current-buffer-file)

快捷键绑定到了ctrl-x ctrl-r上
