According to the shlex documentation:
Return a token. If tokens have been stacked using push_token(),
pop a token off the stack. Otherwise, read one from the input
stream. If reading encounters an immediate end-of-file, an empty
string is returned.
This suggests, for example,
token = mylexer.get_token()
if not token:
or, more tidily,
for token in iter(mylexer.get_token, ''):
These work for me. Is your shlex not working this way?
