TypeLib for Python COM Server?

[billtut at microsoft.com.bbs]

Don't rely on the 1000 thing. You should specifically declare the dispid's
in the Python class.

Hi,

there is no general support for typelib generation. But as I know all
propertiues and methods of a Python COM Server start with the dispid 1000.

So writing the IDL File by hand is no problem. Just take the same GUIDs,
Names and the right DispID. So here is a little example :

Python File :

_reg_clsid_ = "{5B24BFC0-EF45-11d3-9B5F-0090274354BC}"
_reg_libname_ = "PythonComInterpreter Typelib"

class PythonComInterpreter:
    """Interface PythonComInterpreter"""

    _public_methods_ = ['Exec','Eval']

    _reg_progid_     = "PythonComInterpreter"
    _reg_verprogid_  = "PythonComInterpreter.1"
    _reg_clsid_      =  '{281AC1E3-E3D2-11D3-9B37-00902722BDE1}'
    _reg_desc_       = "PythonComInterpreterClass"
    _reg_class_spec_ = "PythonComInterpreter.PythonComInterpreter"

 
    def __init__(self):
        self.Dict = {}
        self.Dict["__name__"] = "__main__"
        self.Dict["__builtins__"] = __builtins__
        self.Dict["__doc__"] = ""

    def Exec(self, Cmd):
        exec str(Cmd) in self.Dict

    def Eval(self, Cmd):
        return eval(str(Cmd),self.Dict)


if __name__ == '__main__':
  print 'Registering Python COM Server ...'
  import win32com.Server.register
  win32com.Server.register.UseCommandLine(PythonComInterpreter)
  print 'Registering finished'

        methods:
            [id(1000), helpstring("Executes a Pythonstatement")]
            VARIANT Exec([in] BSTR cmd);
            [id(1001), helpstring("Evals a Pythonstatement")]
            VARIANT Eval([in] BSTR cmd);
    };
};
