I submitted a patch for python (changing email.Utils->email.utils in
urllib, with similar patches for urllib2 and smtplib). But I agree
that a recipe for py2app would be very good, since some people will
run py2app against 2.5.
The following recipe seems to work, but I don't know if it's really
the right way to go. It is based on extrapolating from the current
recipes. None of them seem to do the same job and I've not found any
docs on writing recipes:
def check(cmd, mf):
m = mf.findNode('email')
if m is None or m.filename is None:
return None
oldNames = [
'base64MIME',
'Charset',
'Encoders',
'Errors',
'Generator',
'Header',
'Iterators',
'Message',
'MIMEAudio',
'MIMEBase',
'MIMEImage',
'MIMEMessage',
'MIMEMultipart',
'MIMENonMultipart',
'MIMEText',
'Parser',
'quopriMIME',
'Utils',
'message_from_string',
'message_from_file',
]
oldModules = ["email." + name for name in oldNames]
return dict(
modules = oldModules,
)
