  32 {{{#!ExportFile file=example.py
  33 #format python
  34 def format(self, formatter):
  35     self.pagename = formatter.page.page_name
  36     self.quoted_pagename = wikiutil.quoteWikinameURL(self.pagename)
  37     attachment_path = AttachFile.getAttachDir(self.request, self.pagename, create=1)
  38 }}}
