V8 的 Python 封裝：PyV8

PyV8 是Google V8 引擎的 Python 語言封裝，這是 Python 和 JavaScript 對象之間的橋，支持在 Python 腳本中調用 V8 引擎。

>>> import PyV8
>>> ctxt = PyV8.JSContext()          # create a context with an implicit global object
>>> ctxt.enter()                     # enter the context (also support with statement)
>>> ctxt.eval("1+2")                 # evalute the javascript expression
3                                    # return a native python int
>>> class Global(PyV8.JSClass):      # define a compatible javascript class
...   def hello(self):               # define a method
...     print "Hello World"    
...
>>> ctxt2 = PyV8.JSContext(Global()) # create another context with the global object
>>> ctxt2.enter()                    
>>> ctxt2.eval("hello()")            # call the global object from javascript
Hello World                          # the output from python script
