A while back I switched from Quicksilver to Launchbar. (Mainly, Quicksilver was too slow on my iBook.) The thing I missed most from Quicksilver was its Backpack plugin. So I wanted a way to recreate it on Launchbar, except Launchbar doesn’t have plugins.

Here’s how I did it. I wrote a Perl script that uses the Backpack API to get a list of all my Backpack pages and their URLs. The script writes out a .webloc file for each page. Then I add that folder of .webloc files to Launchbar. I use the Macaroni prefpane to make sure the script runs every day; you could also make it a cronjob to run every hour or whatever you like.

This is the worst kind of quick-and-dirty Perl script. In short, I hope it doesn’t make your Mac burst into flames, but no promises. It’s been working great for me for a week.

P.S.: I assume it’ll work just as well for Butler or Overflow or Stacks or other launchers.
