gPodder Configuration Editor

I've had the idea of implementing some kind of about:config-like configuration editor for gPodder for some time now. Not only does it give a nice live view of the current configuration settings, it also makes it possible to edit some configuration values that were previously only available by editing ~/.config/gpodder/gpodder.conf by hand.

Apart from that, we might be able to strip down the preferences dialog to only the really important settings and leave everything else in the "advanced" configuration editor :) I think the interface is quite nice and even looks nicer than the real about:config editor. As with Mozilla's about:config editor, this also marks the settings that have been modified from their default value in bold.

Episode selector dialog for gPodder

Today after University, I decided to hack a feature into gPodder that I have thought about for a while - the episode selector dialog. It should be used in several user interaction situations where a simple binary question is not specific enough ("delete old episodes?" vs "which of these old episodes do you really want to remove?"). So I set out implementing this neat little feature and when I looked at the watch and decided that I had to leave for math classes, most of the episodes selector has been implemented, with quite some fancy features and options. I used the last two hours to look through the my working copy diff to fix some obvious omissions, but as of now, the code of the new episode selector is already in SVN. I've attached some screenshots so you can see how it looks.

Thanks to lambda expressions, PyGTK coolness and getattr, i.e. accessing attributes by name, this dialog is now quite customizable and the code is still readable and (compared to what other languages would have yielded), small. If you are using gPodder, be sure to check out the current SVN trunk head.

One feature I used several times was enumerate() - you give an iterable as parameter, and get a generator that yields tuples with two elements - a zero-based index and the values you would normally get from the iterables directly. So, instead of writing code like this:

index = 0
for item in items:
    print 'item %d is %s' % ( index, item )
    index += 1

you can simply write

for index, item in enumerate( items):
    print 'item %d is %s' % ( index, item )

which isn't only nicer, but you save two lines and the code is IMHO more readable (you instantly recognize "index" as being related to the for loop in the second code snippet).

Simplifying gPodder website navigation

Today, I've updated the gPodder website (navigation) to be more usable and easier to navigate. I've added stock Gnome icons and moved some previously top-level items into the "documentation" menu item or elsewhere. This makes navigation easier and the design also looks a bit more modern, have a look:

You can find the new gPodder website at the usual location: http://gpodder.berlios.de/. Oh, and by the way: I've just released a new version (0.9.5) today, so if you're using gPodder, be sure to check out the new release.

Subscribing to podcasts in gPodder

Until today, gPodder users were presented the same dialog for adding and editing "channels" (i.e. podcast subscriptions). When adding a channel, only the URL was needed, so all other UI elements were simply hidden in the dialog. As adding a channel only involves entering one URL, and as our new, shiny channel navigator adds some free space in the lower left corner of the window, I decided to re-work the GUI, inspired by Tasks's main window. Here's the difference:

Of course, with this change, I also had the chance to revise the channel edit dialog a bit (remember, it's the same dialog, used for both adding and editing). Apart from stripping out unneeded code and re-factoring the code, I've tried to make the dialog a bit more pleasant to use. For one, I've removed the cancel button and changed the "OK" button into a "Close" button.

I hope you like the changes and it makes using gPodder a little bit more pleasant. Time to roll another release some time soon..

gPodder gets new channel navigator

My PyGTK pet project, gPodder is currently receiving a bit of a face-lift for its main window. After Carlos Moffat has raised some concern about the usability when being subscribed to many channels and suggested a "sidebar".

So, I first added some unread episodes information to the channel drop down list, so one can easily see where new episodes are to be found. Two e-mails later, I thought I should improve this a bit more and added a gtk.TreeView and a gtk.HPaned onto the Podcasts tab, displaying the top gtk.ComboBox's contents (thanks to the reusability of Gtk's TreeModel structures) in the left pane.

The next step was adding a bit more design to the whole UI, and while fixing many bugs that cropped up while testing the new interface (and cleaning up the source code, for example unifying the new episodes algorithm into a single function), I finally had a nice-looking interface that gives the user much more information about the subscribed channels and new episodes. By using the channel's iTunes cover image (if available) as icon, a user can easily recognize specific podcast channels if the list is huge. Adding a bit of the channel's description below its title also gives a better overview over one's channels. The number in the sidebar tells us how many new podcast episodes are available for the channel. Here's how it looks currently:

The code should be available in gPodder's Subversion repository in the upcoming days after I've cleaned up the commit a bit. Enjoy :)
