Simple program to merge iCal files.
I keep my life in Google. My wife keeps hers in iCloud. We wanted access to each others' calendars. But the useful bits of my calendar are spread across several different Google calendars and I wanted to combine them into a single iCal feed that my wife could subscribe to.
I was surprised to see that this didn't seem to exist as a service (or, at least, if it does, half an hour of Googling couldn't find it - I think Yahoo! Pipes would have done it). But half an hour of Perl hacking produced this simple program which uses the Text::vFile::asData module.
There's a very simple config file. Give your new combined calendar a title and a list of iCal URLs. Run the program like this:
$ mergecal config.json > combined.ics
Then put combined.ics somewhere on the web so iCloud (or whatever) can
see it.
