Fetches the most recent intellij idea x version if not yet installed, to use in daily anacron job or simliar. Very basic functionality, very specific to my setup. But should be easy to adopt.

new-idea.py

#!/usr/bin/env python3

import re
from urllib import request
import os

WEBSITE = "http://confluence.jetbrains.net/display/IDEADEV/IDEA+X+EAP"
MATCH = r".*(http://download\.jetbrains\.com/idea/ideaIU-(\d+\.\d+)\.tar\.gz).*"

with request.urlopen(WEBSITE) as h:
    for line in [x.decode() for x in h.readlines()]:
        m = re.match(MATCH, line)
        if m:
            url = m.groups()[0]
            version = m.groups()[1]

if not os.path.exists('/opt/idea-IU-%s' % version):
    print('Idea will be upgraded to version %s:' % version)
    os.system('wget -qO - %s | sudo tar xzf - -C /opt' % url)
    os.system('sudo rm /opt/idea')
    os.system('sudo ln -s /opt/idea-IU-%s /opt/idea' % version)
