Ruby怎样自定义命令

1 首先在ruby根路径下面的bin目录建立2个文件: yanzilee9292和yanzilee9292.bat。

 

yanzilee9292.bat文件:

 

@ECHO OFF
IF NOT "%~f0" == "~f0" GOTO :WinNT
GOTO :EOF
:WinNT
@"ruby.exe" "%~dpn0" %*

 

 yanzilee9292文件:

 

#!C:/Ruby192/bin/ruby.exe
#
# This file was generated by RubyGems.
#
# The application 'ruby-debug-ide19' is installed as part of a gem, and
# this file is here to facilitate running it.
#

require 'rubygems'

puts "yanzilee9292 test"

load ARGV.shift

 

 

2 编写一个文件test.rb来测试

 

puts "testing"
 

 

3 用自定义命令运行test.rb

D:\test>yanzilee9292 test.rb

yanzilee9292 test
testing 

 

 

可以看出, 本质上还是用的ruby命令来运行。 通过ruby语言的灵活的特性, 可以扩展很多类的方法来实现一个自定义的gem, 比如rspec,rdebug...
