Finally, iCalTV 0.5 is finished. A lot of code has been rewritten, and some great stuff added.
Because I opened iCal all the time to check stuff during development, it took me a while to realize iCal does in fact not update subscribed-to calendars unless you start the program and trigger it manually, or start it and wait for a couple of minutes. For this reason, I rewrote the code quite a lot, to post events to iCal using AppleScript instead.
Rid of the security restrictions on subscribed calendars, I could also add support for running scripts as reminders. This allows cool stuff like Growl notifications and spoken reminders through OS X's speech synthesis. I also added support for multiple reminders.
For most of my favorite shows, I now hear e.g. "Morden i Midsomer on SVT1 in five minutes" along with a pretty, sticky Growl notification. A sticky notification does not hide automatically after a few seconds, so that I don't miss them if I'm temporarily elsewhere. Then one minute before the show starts, I get another spoken alert and a non-sticky Growl notification. It's quite lovely!
