谢谢。
您的代码中存在实现错误。根据markdown的文档，您应该定义要为自定义Extension提供的参数。
如果你还没有任何配置，你应该使用下面的东西：
def makeExtension(configs={}):
return MathJaxExtension(**configs)
完整的实现应该是这样的：
import markdown
import cgi
class MathJaxPattern(markdown.inlinepatterns.Pattern):
def __init__(self, md):
markdown.inlinepatterns.Pattern.__init__(
self, r'(?<!\)($$?)(.+?)2', md)
def handleMatch(self, m):
# Pass the math code through, unmodified except for basic entity
# substitutions.
# Stored in htmlStash so it doesn't get further processed by Markdown.
text = cgi.escape(m.group(2) + m.group(3) + m.group(2))
return self.markdown.htmlStash.store(text)
class MathJaxExtension(markdown.Extension):
def __init__(self, **kwargs):
self.config = {'option1' : ['value1', 'description1'],
'option2' : ['value2', 'description2'] }
super(MathJaxExtension, self).__init__(**kwargs)
def extendMarkdown(self, md, md_globals):
# Needs to come before escape matching because is pretty important
# in LaTeX
md.inlinePatterns.add('mathjax', MathJaxPattern(md), '<escape')
def makeExtension(configs={}):
return MathJaxExtension(**configs)
