rails 资源汇总

1. RbConfig

    ruby的配置文件，安装后就存在, 在安装目录内，可以查看ruby详细的配置信息

    路径示例： C:\Ruby187\lib\ruby\1.8\i386-mingw32\rbconfig

             

    内容示例：

# This file was created by mkconfig.rb when ruby was built.  Any# changes made to this file will be lost the next time ruby is built.module Config  RUBY_VERSION == "1.8.7" or    raise "ruby lib version (1.8.7) doesn't match executable version (#{RUBY_VERSION})"  TOPDIR = File.dirname(__FILE__).chomp!("/lib/ruby/1.8/i386-mingw32")  DESTDIR = TOPDIR && TOPDIR[/\A[a-z]:/i] || '' unless defined? DESTDIR  CONFIG = {}  CONFIG["DESTDIR"] = DESTDIR  CONFIG["PATCHLEVEL"] = "334"  

2. ruby自身带的帮助文件

   ruby安装目录doc下含有一些常用的帮助文件外，还含有booktoruby.pdf一本书，值得一看。
