Ruby转Exe -- Exerb研究

1. Exerb简介

Exerb是一个将ruby脚本程序(.rb)转换成Windows应用程序(.exe)的软件。目前最新版本4.1.0，下载地址：http://downloads.sourceforge.jp/exerb/23470/exerb-4.1.0.zip。

2.安装

把下载的zip文件解压，进入exerb目录，运行ruby setup.rb。这时exerb和mkexy命令将会加入ruby/bin目录中。

3.ruby -> exe

先来个最简单的

hello.rb

1. puts 'Exerb'

运行exerb hello.rb，生成一个hello.exe文件，OK。

下面写个GUI程序，使用wxRuby类库。

hello_wx.rb

1. require 'wxruby'
2. include Wx
3. class MyFrame < Frame
4.    def initialize(title)
5.      super(nil, -1, title)
6.      Button.new(self, -1, "Hello, I'm a Button")
7.    end
8. end
11. class MyApp < App
12.    def on_init
13.      frame = MyFrame.new('Simple wxRuby App')
14.      frame.show
15.    end
16. end
18. a = MyApp.new
19. a.main_loop

exerb hello_wx.rb，生成hello_wx.exe，却不能运行。因为exe并没有把程序所需的类库打包进来，这时候就得执行mkexy命令。

mkexy hello_wx.rb，生成hello_wx.exy文件

hello_wx.exy

该文件把hello_wx.rb所需的类库文件都包含进来了。

运行exerb hello_wx.exy，这时候生成的hello_wx.exe是可以执行的，问题是打开文件的同时会打开一个控制台窗口，要解决这个问题，就得修改hello_wx.exy文件，把cui改成gui。

1. general:
2.   startup: hello_wx.rb
3.   core: gui #cui
4.   kcode: none

再次运行exerb hello_wx.exy，生成一个红宝石图标的exe文件，OK！

另外，exy文件中还可以设置图标和版本信息。不再赘述。配置属性如下：

1. resource:
2. icon:
3. - width : 16
4. height: 16
5. color : 4
6. file : your_ico.ico
7. - width : 32
