import pprint
from trac.wiki.macros import WikiMacroBase
from tracusermanager.profile.api import UserProfileManager
from genshi.core import Markup
from trac.wiki import Formatter
import StringIO
class JMNEInstitution(WikiMacroBase):
# This is no args MACRO
def expand_macro(self, formatter, name, text):
env = self.env
upm = UserProfileManager(env)
profile_fields = upm.get_user_profile_fields()
pprint.pprint(profile_fields)
result = ""
if "institution" in profile_fields:
for perinst in profile_fields["institution"]["options"]:
result += "* %s\n"%perinst
out = StringIO.StringIO()
Formatter(self.env, formatter.context).format(result, out)
return Markup(out.getvalue())
先贴一段代码。
扩展Trac的Macro不是很复杂，首先，需要把这些脚本放到trac项目的plugins中。Trac会加载这里的脚本。

我们只要实现接口expand_macro即可。另外，我们可以在里面使用wiki。
