读-福瑞哈哥-的POE学习笔记

http://bbs.chinaunix.net/thread-908855-1-1.html

wheel部分有个小例子，代码不贴了。

其中有几行：

1. ? ? ? ? # 告诉ReadLine监控终端
   ?
2. ? ? ? ? $console->get( 'input your message,bye to quit: ');
   ?
3. ? ? ? ? $heap->{console} = $console;
   ?

原以为$console->get仅仅是终端输出，所以在copy脚本的时候就删掉了。结果怎么调代码都不回显，server端也收不到东西。

cpan上关于这个get函数的说明：

get

get() causes POE::Wheel::ReadLine to display a prompt and then wait for input. Input is not noticed unless get() has enabled the wheel's internal I/O watcher.

After get() is called,the next line of input or exception on the console will trigger an InputEvent with the appropriate parameters. POE::Wheel::ReadLine will then enter an inactive state until get() is called again.

Calls to get() without an argument will preserve the current prompt. Calling get() with an argument before a whole line of input is received will change the prompt on the fly.

悲催啊。。。。。
