考场配置：

;;在配置后面会对语句逐一解释的(global-set-key (kbd "C-z") 'undo)
(global-set-key (kbd "RET") 'newline-and-indent)
(global-set-key [f9] 'compile-file)
(global-set-key [f10] 'eshell)

(setq default-cursor-type 'bar)
(setq default-tab-width 4)
(setq c-default-style "awk")
(set-frame-parameter (selected-frame) 'alpha (list 85 50))(setq default-frame-alist'((background-color . "black")(foreground-color . "grey")(cursor-color . "gold1"))

语句解释：

(global-set-key (kbd "C-z") 'undo)
(global-set-key (kbd "RET") 'newline-and-indent)
(global-set-key [f9] 'compile-file)
(global-set-key [f10] 'eshell)
(defun compile-file ()(interactive)(compile (format "g++ -o %s %s -g -lm -Wall"  (file-name-sans-extension (buffer-name))(buffer-name))))
;;快捷键第一行是撤销，第二行自动缩进，第三行编译，第四行进入eshell界面准备运行，后面一段是一键编译（按F9执行）。(cua-mode t)
;;Windows的复制粘贴键（在emacs上方菜单栏即options中有开关选项！(show-paren-mode t)
(global-linum-mode t)
;;括号匹配和显示行号(electric-pair-mode t)
;;这个真的敲级好用，一行配置直接打开（大中小）括号和引号的自动补全！！！(global-hl-line-mode 1)
;;显示当前行（使当前行颜色不同，便于区分）-(setq kill-ring-max 200)
;;设置撤销的缓存，可以开大点避免失误，这里博主开了200！(setq default-cursor-type 'bar)
;;光标为竖线（要防止光标闪烁，在菜单的options里有开关选项！）(setq default-tab-width 4)
;;默认tab宽度为 4(setq c-default-style "awk")
;;缩进风格（考场挂了QAQ(set-frame-parameter (selected-frame) 'alpha (list 85 50))
;;透明度（一边敲代码一边看题不用老是切换页面）
;;前一个数字表示你选中这个页面时的透明度，后一个数字是你没选中此页面时的透明度(setq default-frame-alist'((width . 200)(height . 43)(background-color . "black")(foreground-color . "grey")(cursor-color . "gold1")(tool-bar-lines . 0))
);;初始设置：宽度，高度，背景颜色，字体颜色，光标颜色，以及是否有菜单工具栏

注意事项：

1.## 不要弄太多配置，考场容易码错
2.## 一般考试会提前20分钟入场，这段时间可以码配置（如果管得比较松

平时码代码添加的一些小配置：

(setq frame-title-format "%b by xiao-wen")
;;改变emacs标题栏的标题（特爽）(set-face-foreground 'region "gold1")
(set-face-background 'region "gray15")
;;（区域）选择的背景和主题;;(set-face-foreground 'highlight "white")
(set-face-background 'highlight "gray15")
;; 设置语法高亮显示的背景和主题（第一个去分号使用(defun up-slightly () (interactive) (scroll-up 3))
(defun down-slightly () (interactive) (scroll-down 3))
(global-set-key [mouse-4] 'down-slightly)
(global-set-key [mouse-5] 'up-slightly)
;;上下滚动时不会太快（一次只上下移动三行，极舒服）(defun my-c-mode-auto-pair ()
(interactive)
(make-local-variable 'skeleton-pair-alist)
(setq skeleton-pair-alist '(
(\( ? _ ")")
(\[ ? _ "]")
(\' ? _ "'")
({ \n > _ \n ?} >)))
(setq skeleton-pair t)
(local-set-key (kbd "(") 'skeleton-pair-insert-maybe)
(local-set-key (kbd "'") 'skeleton-pair-insert-maybe)
(local-set-key (kbd "[") 'skeleton-pair-insert-maybe)
(local-set-key (kbd "{") 'skeleton-pair-insert-maybe))
(add-hook 'c-mode-hook 'my-c-mode-auto-pair)
(add-hook 'c++-mode-hook 'my-c-mode-auto-pair)
;;自动补全右边的部分.包括 "", '' , (), [] , {} 等等。
;;这里我只写了括号（大中小都有）和引号
;;较上面那个一行的配置来说（这个可以做到同时删去
;;但是考场应该用哪个，这就不用多说了吧(custom-set-variables'(column-number-mode t)'(cua-mode t nil (cua-base))'(display-time-mode t)'(inhibit-startup-screen t)'(show-paren-mode t)'(tool-bar-mode nil))
(custom-set-faces'(default ((t (:family "Ubuntu Mono" :foundry "unknown" :slant normal :weight normal :height 143 :width normal)))))
(auto-insert-mode)
(setq auto-insert-directory "~/.emacs.d/mytemplates/")
(setq auto-insert-query nil)
(define-auto-insert "\." "moban.cpp")
(electric-pair-mode t)
;;这个是部分emacs自带的（有时间字体的基础配置

其他：

;;(setq inhibit-startup-message t)
;;启动画面关闭;;(c-set-style "stroustrup")
;;(c-toggle-auto-state)
;;(c-toggle-hungry-state)
;;(setq c-basic-offset 4)
;;(imenu-add-menubar-index)
;;(which-function-mode)))
;;把C++语言风格设置为stroustrup风格，博主也不知道是啥东西

提醒一下：语句要去掉前面两个分号使用

以上代码直接复制到emacs配置可以正常运行！
