• Initiate script from Quicksilver
• Grab URL from the front-most window in Safari
• Submit URL to URL shortening service (previously xrl.us, but more recently bit.ly)
• Copy shortened URL to system clipboard (for pasting into Twitterific)
• Notify of process completion via Growl

I’ve tried a number of different workflows including bookmarklets and the like, but this one works best for me (read: I honestly don’t care what you think of this flow or what you do instead… this is what I prefer).

Recently I discovered a new URL shortening service, tr.im, and decided to give them a try. However, unlike most services, tr.im doesn’t simply return the shortened URL. Instead it returns either an XML or JSON structure that includes the shortened URL along with some other data. Quickly realizing that AppleScript doesn’t handle JSON very well, I decided that this would be a good opportunity to start learning Python. The result was the following Python script:

http://willnorris.com/svn/homedir/packages/tools/local/bin/trimURL

It follows the same flow as mentioned above, making use of a couple of Python modules (which are required for running this script): simplejson and appscript. Put this script in a directory that Quicksilver scans (I think the Terminal Quicksilver plugin is also required). If you want to authenticate to tr.im, add your username and password to your ~/.netrc file. I also set the script’s file icon to be the tr.im icon, so it will be displayed in the Growl notification.

[Update: I discovered my previous solution didn’t persist between restarts of Quicksilver, so here is a working solution] It’s pretty simple…

• First make sure you have the “Extra Scripts” plugin installed
• open your Quicksilver Preferences and go to your catalog.
• Add a new “File & Folder Scanner” and point it to ~/Library/Application Support/Quicksilver/PlugIns/Extra Scripts.qsplugin/Contents/Resources/ExtraScripts
• Set “Include Contents: Folder Contents” and “Depth: infinite”

After reading the comments in this hint at macosxhints.com, I discovered this little bit of applescript.

tell application "ScreenSaverEngine" to activate

You’ll want to add this to a Quicksilver trigger so you can it from the keyboard (I use Cmd-Opt-Shift-L because that was the default in locktight and I’m kinda used to it)

I originally used MenuTunes, and most recently Synergy to provide global “hotkeys” to do some simple things like play/pause iTunes, skip to next or previous track, and display some information about the current track. Quicksilver’s triggers are ideal for this — it allows you to create keyboard shortcuts to perform any Quicksilver action. This let me setup keys for play/pause and next/previous track.

Additionally I setup the iTunes Quicksilver plugin to display track notifications and to send those notifications to Growl, however the plugin only displays notifications when something happens like the track changes. I want to be able to display track info at any time so I whipped up this simple Applescript, saved it to my scripts folder, and assigned it to a Quicksilver trigger. This will display the exact same as the built-in iTunes notification in Quicksilver with the addition of track time, current position, and ratings stars. It’s a very simple matter of displaying more or less info for the track.
