打算把twisted移植到D语言上

twisted是一个优秀的python网络开发库，以前用它做过一个视频服务器，感觉它的接口应该比ACE更适合D一些。

twisted虽然是用python所写，但借助于Zope的interface模拟，很大程度上改善了动态语言开发的无接口约束的缺点。

由于它有一整套规范化的接口，所以应该先把它的接口转化过来，方便编写测试。简单看了一下TwistedCore，这个是twisted最基本的部分，先把twisted.internet转化过来吧。

python反射支持得不错，ZopeInterface也做了一些工作，所以可以利用它帮我完成一部分工作。我写了个脚本来转化这些接口：

from twisted.internet import interfaces;

def convert_interface(interface):
    result = "/**\n\t" + interface.__doc__ + "\n*/\n"
    result += "interface %s {\n" % interface.getName()
    for name, method in interface.namesAndDescriptions():
        result += "\t/**\n\t\t" + method.__doc__ + "\n\t*/\n"
        result += ("\tvoid %s%s;\n" % (name, method.getSignatureString()))
    result += "}\n\n\n\n"
    return result

output = "/**\n" + interfaces.__doc__ + "\n*/\n\n\n\n"

for interface in [x for x in dir(interfaces) if x[0] == "I"]:
    output += convert_interface(getattr(interfaces, interface))

print output

执行，输出结果如下：

辛苦了几个晚上转换了一些文件，发现很不值得，要转换的东西太多了。自己从头写了个简单的select实现，1个小时就可以有个雏形，加入timer支持也很容易，只要把timer排序，再设置好select超时即可。
