Importing the code won't give you access to the req (request) instance.
The request object is not available from the macro body.
The authname is also available from the hdf instance.
Michael, you could try something this:
#----- Link.py ---
from trac.wiki.formatter import Formatter
import string
def execute(hdf, args, env):
(url, name) = map(string.strip, args.split(','))
return '<a href="%s?user=%s">%s</a>' % (url, hdf['trac.authname'], name)
#-----
Example:
[[Link(http://example.com, Example)]]
Of course, you probably need to deal with error cases (authname not
defined when user is not logged in, etc.)
Cheers,
Manu

Just looking at the error message from the python code -- without
knowing about macro development for trac -- the instance req is not
defined. You need to import it from somewhere, probably the trac module.
Try adding:
from trac.core import *
at the top of your file.
I got that from some code snip I found by following the help link of a
trac webpage.
Cheers,
Guenter
