Introspection Introspection

Posted in Programming and Technical, Ubuntu on March 6th, 2012 by doctormo

I’ve written a script which I can use to get information about gobject introspection modules for use in python. It’s written in python and allows you to look at actual function names, actual object names and what really is going on.

http://paste.ubuntu.com/872138/

This is mainly a problem because the documentation for Gtk with gi.repository is so poor and not clearly described that it makes it impossible to use without great force of will.

Hopefully this script can make the job easier for others, feel free to adapt it and post your remixes.

XBMC Librarian (New Addon)

Posted in Free and Open Source Software, Programming and Technical, Ubuntu on August 31st, 2011 by doctormo

Hello Community,

I’ve finished writing a new addon for xbmc (the tv media center for Ubuntu) called Librarian. She will take a look at your impressive video library and check for various inconsistencies and potential problems which you might want to look into. This 1.0 release includes the following features:

  • List Movie Files not Included in the Database
  • List Movies which have incorrect length, i.e. misidentified or corrupt (requires ffmpeg installed)
  • Lists TV Shop Episodes separately with both above features
  • Tells you which seasons and which episodes of each show you’re missing
  • Shows you which TV Show Paths are being ignored completely.

More checking can be added as good ideas come in, I’ve also written an addon module called xbmcdata which wraps sqlite3 the xbmc httpapi to give a consistant inside xbmc and outside testing/scripting interface. This makes addon development _much_ easier. For instance listing movies is now just a case of:

from xbmcdata import Movies

for movie in Movies():
    print "%s (%s)" % (unicode(movie), movie['Year'])

Please download the code here: http://divajutta.com/doctormo/doctormo-xbmc-addons.tar.gz and install in ~/.xbmc/addons/ then test, entry is available under ‘Programs’. Please report issues back to me with full logs from ~/.xbmc/temp/xbmc.log included.

Have fun.

Registration Form, Gtk Forms

Posted in Ubuntu on April 26th, 2011 by doctormo

The GtkMe python lib provides a form window which allows me to construct a multi-page form with data validation. I’m pleased with the results I’ve committed today that allow a new user to register themselves within the login screen.

class RegisterWindow(TranslatableFormWindow):
"""Display a create user window"""
name = 'register'
primary = False
fields = [ 'postcode', 'age', 'gender', 'passphrase', 'computeruse' ]
def __init__(self, *args, **kwargs):
self.realname = kwargs.pop('real_name')
TranslatableFormWindow.__init__(self, *args, **kwargs)
intro = self.widget('label').get_label()
self.widget('label').set_label(intro % self.realname)
def cancel(self, widget, event=None):
if isinstance(widget, Gtk.Button) or (event and \
event.key.keyval == Gdk.KEY_Escape):
self.destroy()
def get_data(self):
"""Return all the user entered data"""
result = self.field_data()
result['name'] = self.realname
return result
def pre_exit(self):
register_service.create_user(self.get_data())

While I’m not finished debugging it all, the idea is to be able to make Gtk apps which have a wizard style layout with minimum effort. Each page has validation checks (if you want) and standard signals which you can stick into glade and have next, back, cancel and destroy handled for you.

This code controls a 5 page registration window as so:

Thoughts?
