在emacs的配置文件(~./.emacs.d/init.el)文件里添加以下内容:python
(add-to-list 'load-path "/usr/share/emacs/site-lisp")
(require 'linum)
(global-linum-mode t)linux
首先应该先检查字体配置, 而后检查是否开启eamcs的xft的USE标示符.c++
安装 font-cursor-misc 或 font-adobe-75dpi ,重启计算机测试(好像大部分是由于缺乏这个语言包的问题)正则表达式
安装:markdown
1). [ebuild N ] media-fonts/font-adobe-75dpi-1.0.0 USE="X nls" 0 kB 2). [ebuild N ] x11-apps/bdftopcf-1.0.2 USE="-debug" 0 kB 3). [ebuild N ] media-fonts/font-alias-1.0.1 USE="-debug" 0 kB 4). [ebuild N ] media-fonts/font-util-1.1.1 USE="-debug" 0 kB
(setq frame-title-format ("%S" (buffer-file-name "%f" (dired-directory dired-directory "%b"))))
app
(setq frame-title-format "XX@%b"),其中XX为本身的电脑名,或本身可任意取名,甚至能够不须要。ide
从 Emacs 24 开始,Emacs 对扩展包进行统一管理,极大程度上简化了扩展包的搜索与安装过程。打开 Emacs,而后执行 M-x list-packages ,若是网速足够快,应该很快就能看到 Emacs 官方提供的扩展包列表。工具
待软件包列表出现后,执行 C-s M-r ^ +company ,回车便可让光标跳到 company 扩展包信息所在的文本行,继而敲击 i 键(表示要安装该扩展包),再敲击 x 键(表示执行安装过程),稍等片刻,Emacs 会自动从下载 company 扩展包并安装至 $HOME/.emacs.d 目录。测试
提示:C-s 是开启 Emacs 查找模式, M-r 是将查找模式切换为正则表达式查找模式,而 C-s(ctrl +s) M-r(Alt + r) ^ + company 是用于匹配『位于行首且由多个空格与 company 字符串构成的字符串』的正则表达式。字体
若是之后要删除 company 扩展,步骤与安装步骤相似,只是将 i 键替换为 d 键(表示删除)。company 安装完毕后,在 Emacs 配置文件中作如下配置:
;; 代码补全
(add-hook 'c-mode-hook 'company-mode)
(add-hook 'c++-mode-hook 'company-mode)。
对于pcl的代码提示功能,只须要安装 company的关于C/C++的头文件便可.(目前是这样的)
在linux下,若emacs启动较慢,可经过hostname查看本身主机的名字,而后打开/etc/hosts文件,将其中localhost改成本身主机名
