 Posted: Fri Mar 04, 2005 3:59 am Post subject: Nifty GMail Checker Script |
 |
|
Hey,
So I just wrote a python based GMail checker that uses pyosd (python bindings to xosd - X onscreen display lib) and feedparser (RSS/Atom parser) to grab GMail atom feeds and tell me what's in my inbox. The results are displayed on the overlay on my screen, and the font and color and stuff are customizable.
Anybody want to use it? Give feedback? One thing I couldn't do was figure out a way to send the password securely. At the moment, I just have the program using wget and http authentication to snag the Atom feed before my program parses it. Feedparser is supposed to provide a mechanism that sends passwords, but it either didn't work or else it just didn't work with GMail.
Libs needed:
feedparser - www.feedparser.org (not in portage yet)
pyosd - emerge pyosd
wget - emerge wget
Here's the program - notice how it's templateable:
| Code: |
#!/usr/bin/python
TODO = \
"""
- Make authentication secure.
- Use feedparser for auth.
- Improve date format options.
- Enforce width on all lines, including non $$>'ed lines.

That's a pretty cool script. Mind if I use it? I cut it down to a single function that simply returns how many unread emails you have.
| Code: |
#!/usr/bin/python
import feedparser, os
from tempfile import *
def checkmail ( user, password ) :
parameters = {
'url' : "http://gmail.google.com/gmail/feed/atom/",
'user' : user,
'password' : password
}
#Make a tempfile
feedFile = NamedTemporaryFile('w+b',-1,'.xml','pox')
#Grab the feed
os.system("wget -q -O " + feedFile.name + " --http-user=" + parameters['user'] + " --http-passwd=" + parameters['password'] + " " + parameters['url'])
#Parse the feed
feed = feedparser.parse(feedFile.name)
messages = len(feed.entries)
return messages

Excellent - I need to give gdesklets a try again. I installed it once, and it looked cool, but ran really slowly. However, my computer's been running a lot more quickly since I installed 2.6.10 kernel.
Also, something I need to do with this code (and maybe you can help me) is use feedparser's built in support for grabbing password protected xml feeds from the web. The wget thing is just a workaround, even if everyone and their brother has wget. Like I said in the first post, I tried using feedparser to do all of the work, but after I followed the instructions in the feedparser docs explicitly, things still didn't work. I probably just need to contact the feedparser guy.

Ya but I've never had any luck using pop notification applets. This way of checking by xml is quick and works without a hitch.

FWIW, the much simpler notifier I wrote a couple months ago uses libgmail and is probably more secure.
But this atom feed and pyosd stuff is pretty nifty. |

Okay i redid this script in php for the fun of it, plus this thread was a bit dated when i found it and didnt work for me:
| Code: |
#!/usr/local/bin/php -q
<?php
$username = ""; //username goes here no @gmail.com needed
$password = ""; // pasword goes here obviously
$data = exec("wget -O - --http-user=$username --http-passwd=$password https://mail.google.com/mail/feed/atom/ 2> /dev/null");
preg_match('#<fullcount[^>]*>(.*?)<\/fullcount>#i',$data,$matches);
echo $matches[1];
?>
|
All it does is tell me how many unread messages i have, i use it in conky

Love how to redirect the errors into nothingness. Maybe that should go to a log or something?
