Emacs-008-边栏行号显示
Emacs中,边栏行号显示比行号模式要直观多了。开启可以通过命令输入的方式开启,用到的命:linum-mode。这个命令也有点像开关的行为,重复输入会不断进行设置状态的翻转。
通过linum-mode开启的效果:

 

Emacs-008-边栏行号显示_Emacs

再次输入,出现的效果:

Emacs-008-边栏行号显示_开发环境_02

 
如果希望Emacs启动的时候就开启这个功能,需要在.emacs配置文件中加入以下配置:
(global-linum-mode t)
目前我个人的Emacs配置文件积累到如下状态:
(custom-set-variables
 ;; custom-set-variables was added by Custom.
 ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.
 )
(custom-set-faces
 ;; custom-set-faces was added by Custom.
 ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.
 '(default ((t (:family "Courier New" :foundry "outline" :slant normal :weight normal :height 98 :width normal)))))
;; Disable files backup function
(setq make-backup-files nil)
(setq line-number-mode t)
(global-linum-mode t)
