python3 gmail and conky [solved by using python2]

tawan · 2010-10-19 10:05:08

I have become quite dependent on conky displaying the contents of my gmail mailboxes and something seems to have broken since python3 came about.

Can anyone with python knowledge point me to how to get it working again?

Old code

## needs The urllib and feedparser Python libraries

import sys
import urllib3             # For BasicHTTPAuthentication
import feedparser         # For parsing the feed
from textwrap import wrap

_URL = "https://mail.google.com/gmail/feed/atom"

uname = sys.argv[1]
password = sys.argv[2]
maxlen = sys.argv[3]

urllib.FancyURLopener.prompt_user_passwd = lambda self, host, realm: (uname, password)
    
def auth():
    '''The method to do HTTPBasicAuthentication'''
    opener = urllib.FancyURLopener()
    f = opener.open(_URL)
    feed = f.read()
    return feed

def readmail(feed, maxlen):
    '''Parse the Atom feed and print a summary'''
    atom = feedparser.parse(feed)
    print '%s' % (len(atom.entries))

if __name__ == "__main__":
    f = auth()  # Do auth and then get the feed
    readmail(f, int(maxlen)) # Let the feed be chewed by feedparser

error

 File "theabovescript.py", line 26
    print '%s' % (len(atom.entries))
             ^
SyntaxError: invalid syntax

I think there is no substitution with % anymore, and print is now a function.

Try

print("{0}".format(len(atom.entries)))

or

print(len(atom.entries))

Edit: I would also suggest that the function 'readmail' returns the value instead of just printing it. 'maxlen' is not used either, or am I missing something?

def readmail(feed):
    '''Parse the Atom feed and print a summary'''
    atom = feedparser.parse(feed)
    return len(atom.entries)

and

print(readmail(f)) # Let the feed be chewed by feedparser

For python3

print '%s' % (len(atom.entries))

should be

print ('%s' % (len(atom.entries)))

However the script won't work anyway since urllib3 depends upon python2 not python3. So, you'd better update your conky to invoke python2 instead of python (which is python3)

doesn't work if you add on the first line in your script #!/usr/bin/python2 ?

tawan · 2010-10-19 12:32:55

So far still broken here. Thanks for the ideas.

After some more Gooogling it turns out the feedparser is broken under python3.

I did think the idea of running the script as python2 would work but no...

exactly what errors do you get when running your script in a terminal with python2?

conkyemail works if you run it with python2. You might be able to use that or find inspiration in the source. . .

great the above should get me up and running again thanks!

tawan · 2010-10-20 08:04:06

Fixed the original script

I added the shebang for python2 and also edited the bash script I use to call the script as python2 - thanks for all the ideas, truly solved now.

Let me know if anyone successfully ports this to python3. I've been trying, but it's not as easy as I expected

dlin · 2010-10-25 05:34:08

/usr/bin/2to3 -w foo.py # change the code to valid python3 usage.

I've managed to hack this together:

#!/usr/bin/env python
import urllib.request
import re

URL = "https://mail.google.com/gmail/feed/atom"

username = "username"
password = "********"

def find(term, lines):
    for line in lines:
        if re.search(term, line):
            return line

    print("?")
    exit(1)

def get_feed():
    auth_handler = urllib.request.HTTPBasicAuthHandler()
    auth_handler.add_password(realm = "New mail feed", uri = "https://mail.google.com/", user = username, passwd = password)
    opener = urllib.request.build_opener(auth_handler)

    urllib.request.install_opener(opener)

    try:
        feed = urllib.request.urlopen(URL).read()
    except urllib.error.URLError:
        print("?")
        exit(1)

    return feed

xml = get_feed()
xml = xml.decode()
linebyline = xml.splitlines()

count = find("<fullcount>", linebyline)
count = re.sub("^.*(\d+).*$", r"\1", count)
print(count)

Thanks for the above - my python2 script broke again recently, even with the hacks, so I've taken your python3 one and adapted to my needs
