  对于Visual Studio的宏,大家应该很熟悉了,这是一篇关于JBuilder实现类似Visual Studio的宏扩展功能,我们就通过对一段代码是否注释掉作为简单例子。大家可以实现自己的一些扩展,算是抛玉引砖了。

  对于Visual Studio的宏,大家应该很熟悉了,这是一篇关于JBuilder实现类似Visual Studio的宏扩展功能,我们就通过对一段代码是否注释掉作为简单例子。大家可以实现自己的一些扩展,算是抛玉引砖了。
  
  支持环境: Jbuilder 4.0 - JBuilder 7.0
  
  使用JBuilder编译时需要在 Project ---> Project Properties ---> Required Libaries中加上Jbuilder下的 Open Tool SDK,编译成功后将生成的class打包成一个JavaCommentSwitch.jar文件,其中包含这样一个文件META-INF\Manifest.mf,该文件内容如下:
  
  Manifest-Version: 1.0
  
  OpenTools-UI: JavaCommentSwitch
  
  不需要什么详细的讲解,代码如下:
