wnck FTW!

well, yesterday’s hack turned out to be pretty useless.  effectively it just converted hamster into zeitgeist journal (or gnome activity monitor)  – which is okay until you start using an app which isn’t a zeitgeist data provider or which doesn’t happen to emit a signal for the activity you’re performing.

so, i thought i’d have a go at converting hamster into creeper instead.  thanks to creeper for showing me how it’s done.  i’ve called this cree.py 😉

#!/usr/bin/python

# a python version of creeper (a vala app) to monitor active windows
# actually turns hamster into creeper

# because the mainloop appears to catch exceptions
from traceback import print_exc
import hamster.client
class hamster_handler(hamster.client.Storage):
   def __init__(self):
      self.nc = None
      hamster.client.Storage.__init__(self)
      
   def add_fact(self, fact):
      # FIXME insert clever rules here
      fact = fact.replace(",", ";") # don't accidentally create descriptions
      fact = fact.replace("@", "(a)") # don't accidentally create categories
      hamster.client.Storage.add_fact(self, fact)

   def handler(self, scr, prev = None):
      try:
         if prev and self.nc != None: prev.disconnect(self.nc)
         win = scr.get_active_window()
         if win:
            self.add_fact(win.get_name())
            self.nc = win.connect("name_changed", self.name_handler)
      except KeyboardInterrupt: raise
      except:
         print_exc()
        
   def name_handler(self, win):
      try:
         self.add_fact(win.get_name())
      except KeyboardInterrupt: raise
      except:
         print_exc()

hh = hamster_handler()
from gobject import MainLoop
ml = MainLoop()
from wnck import screen_get_default
sc = screen_get_default()
sc.connect("active_window_changed", hh.handler)
sc.connect("window_stacking_changed", hh.handler)
hh.handler(sc)
ml.run()

this is working pretty well for me so far .. on fedora 14.  just tried on 13 and the hamster python library is too old i think.  ah well – yet another reason to upgrade!

python, hamster and zeitgeist FTW!

update: note that this turned out not to be all that useful – tracking active windows into hamster turned out better.

in response to gnome bug 639018 and my general desire to track automatically what i’ve done, i’ve made a python script which connects to the zeitgeist activity monitor and copies its messages to the hamster time tracker.  it goes like this:

#!/usr/bin/python

# monitor zeitgeist and do stuff
from zeitgeist.client import ZeitgeistClient
from zeitgeist.datamodel import TimeRange, Event
from gobject import MainLoop

import hamster.client
class hamster_handler(hamster.client.Storage):
   def handler(self, tr, ev):
      # because the mainloop appears to catch exceptions
      from traceback import print_exc
      from urlparse import urlparse
      try:
         # FIXME insert clever rules here
         app = urlparse(ev[0].actor).netloc
         desk = open("/usr/share/applications/" + app)
         comments = filter(lambda x: x.startswith("Comment[en_GB]="), desk)
         comment = comments[0].split("=")[1].strip()
         self.add_fact(comment + " - " + ev[0].subjects[0].text)
      except:
         print_exc()

hh = hamster_handler()
ml = MainLoop()
ZeitgeistClient().install_monitor(
    TimeRange.from_now(),
    [Event()],
    hh.handler,
    hh.handler)
ml.run()

It never ends until it’s killed so you’ll probably want to run it in the background – i’ve added it to my session ‘startup applications’.  if it doesn’t appear to be working then run it from the command line instead – you should see some error messages if it’s failing to update hamster.

on my fedora 14 system i only get updates for local text files, images and videos opened in gedit, EoG and totem.  on ubuntu i imagine you’ll get a lot more updates.  OTOH, on ubuntu the script will probably need some tweaking for the hard-coded paths and locale.

under surveillance

i’ve decided not to link this to my hamster-to-empathy updater – i don’t really want to broadcast a stream of every little thing i do .. particularly if my IM accounts include twitter and facebook status feeds.  🙂
