RE: [Mailman-Developers] Protecting email addresses from spam harvesters

[Damien Morton]

Hmm, Ill have a bash at it. 

Its better than no protection at all, and its easy enough to do.


A function that resolves entities isnt hard to write though, heres one:

rentity = re.compile(r"&(\w+);")
rhashentity = re.compile(r"&#(\d+);")

from htmlentitydefs import entitydefs

#escapes entities of the form 'ϧ' and '&aaa;' into ascii strings
def unentity(s):
    s = rentity.sub(lambda m: entitydefs.get(m.group(1), m.group()), s)
    s = rhashentity.sub(lambda m: chr(int(m.group(1))), s)

It's a shame you cant define your own entities in html.
