emacs的ruby-mode

想在emacs里面安装ruby-mode, 具体步骤如下：

 

1. 把ruby安装包/misc下面的el文件都拷贝到emacs的site-lisp目录下。

cp ruby/misc/*.el /usr/share/emacs/site-lisp/

 

2. 编辑.emacs文件，将下面代码加进去。

(autoload 'ruby-mode "ruby-mode"
  "Mode for editing ruby source files" t)
(setq auto-mode-alist
      (append '(("\\.rb$" . ruby-mode)) auto-mode-alist))
(setq interpreter-mode-alist (append '(("ruby" . ruby-mode))
                                     interpreter-mode-alist))
(autoload 'run-ruby "inf-ruby"
  "Run an inferior Ruby process")
(autoload 'inf-ruby-keys "inf-ruby"
  "Set local key defs for inf-ruby in ruby-mode")
(add-hook 'ruby-mode-hook
          '(lambda ()
             (inf-ruby-keys)))
