Question

我尝试在我的Windows机器上编译Pyparsing，但遇到以下错误：

python setup.py build_ext --inplace
running build_ext
cythoning pyparsing.pyx to pyparsing.c

Error compiling Cython file:
------------------------------------------------------------
...
       If C{include} is set to true, the matched expression is also parsed (the
skipped text
       and matched expression are returned as a 2-element list).  The C{ignore}
       argument is used to define grammars (typically quoted strings and comment
s) that
       might contain false matches.

我使用Microsoft Visual C ++ 2008 Express版进行了编译，使用的Pyparsing模块是最新版本。请问，有没有人知道如何使这项工作？

先生，我按照你的说法做了，但仍然有编译时警告：


    python setup.py build_ext --inplace
    running build_ext
    cythoning pyparsing.pyx to pyparsing.c
    warning: pyparsing.pyx:413:8: Unreachable code

    \Desktop\pyparsing\pyparsing.pyd;2

警告实际上在第4行：警告：pyparsing.pyx：413：8：无法访问的代码。然后我将该行改为：


    def __getattr__( self, name ):
            if True: #name not in self.__slots__:
                if name in self.__tokdict:
                    if name not in self.__accumNames:
                        return self.__tokdict[name][-1][0]
                    else:
                        return ParseResults([ v[0] for v in self.__tokdict[name] ])
                else:
                    return ""
            else:
                return None

然后重新编译它。我注意到的一件事是，即使我发出警告和编辑，它们都成功编译，但是当我尝试使用以下代码进行测试时：


    from pyparsing import Word, alphas
    greet = Word(alphas) + ',' + Word(alphas) + '!'
    greeting = greet.parseString('Hello, World!')
    print greeting

我收到以下错误：


    Traceback (most recent call last):
      File "C:\nwaomachux\build_pyparsing\checkout.py", line 1, in 
        from pyparsing import Word, alphas
      File "pyparsing.pyx", line 3414, in init pyparsing (pyparsing.c:100064)
    AttributeError: 'builtin_function_or_method' object has no attribute 'ANY_VALUE'

我会进一步更改文件并将其发送给您检查，但我只有几个小时的Pyparsing，所以我还没有掌握完整的源代码。

我不知道将 withAttribute.ANY_VALUE = object（）移动到 def withAttribute（ args， *）开头的效果是什么attrDict）：功能表示。请问，它有什么问题？感谢。

我怀疑问题是使用'include'作为命名参数，因为include是保留的C关键字。尝试将此__init__例程编辑为：

def __init__( self, other, include_=False, ignore=None, failOn=None ):
    super( SkipTo, self ).__init__( other )
    self.ignoreExpr = ignore
    self.mayReturnEmpty = True
    self.mayIndexError = False
    self.includeMatch = include_
    self.asList = False
    if failOn is not None and isinstance(failOn, basestring):
        self.failOn = Literal(failOn)
    else:
        self.failOn = failOn
    self.errmsg = "No match found for "+_ustr(self.expr)

也就是说，只需在参数列表中以及引用它的一行中为参数名称添加“_”。这将使您的Cython编译的pyparsing与标准版本略有不同，但我没有看到大量使用此参数。

祝你好运，请发布pyparsing wiki Home page discussion您的Cython-izing经验，以及有关如何加快您的pyparsing过程的任何信息。

如何在WIndows上使用Cython编译Pyparsing？
