setWeblocThumb

This is a small command-line program for OS X that assigns custom icons to Web Internet Location (.webloc) files, displaying a thumbnail of the web page that they point to.

This is what the icons look like:

Usage

Here's the usage info of this program (run it without any arguments to see this):

usage: setWeblocThumb [options] <path>

  a thumbnail of the web page that they point to.

  <path> may point to a .webloc file or a directory
  that contains .webloc files.

  [options:]

  -f  sets icons also for files that already have a
      custom icon (they are ignored by default).

  -ni doesn't load the site's favicon image and add it to
      the generated icon.

Automating It

If you'd like to have this program run automatically whenever you add .webloc files somewhere (e.g. by dragging them from your web browser windows), I suggest using a launch agent. An example launchd configuration file is provided with the distribution package, which asks the system to run setWeblocThumb every time the Desktop folder is modified (e.g. if some files are added there). Below are some directions on how to take it into use:

1. Make a copy of the provided example launch agent configuration file into the LaunchAgents folder in your Library:

   	
   $ mkdir -p ~/Library/LaunchAgents
   $ cp "example launchAgents/org.hasseg.setWeblocThumb.desktop.plist" ~/Library/LaunchAgents/.
   	

2. Edit this file and verify that the paths are correct (i.e. replace your_username with your actual username, or change the paths completely):
   

   	
   <?xml version="1.0" encoding="UTF-8"?>
   <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" 
    "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
   <plist version="1.0">
   <dict>
   	<key>Label</key>
   	<string>org.hasseg.setWeblocThumb.desktop</string>
   	<key>ProgramArguments</key>
   	<array>
   		<string>/usr/local/bin/setWeblocThumb</string>
   		<string>/Users/your_username/Desktop</string>
   	</array>
   	<key>WatchPaths</key>
   	<array>
   		<string>/Users/your_username/Desktop</string>
   	</array>
   </dict>
   </plist>
   	

3. Tell launchd to load this launch agent:

   	
   $ launchctl load ~/Library/LaunchAgents/org.hasseg.setWeblocThumb.desktop.plist
   	

To learn more about launchd, launchctl and launch agents, please refer to Apple's documentation.

Also note that you can achieve similar functionality (i.e. run setWeblocThumb every time files are added to a particular folder) by other means as well, such as folder actions and the Hazel application. I use launchd simply because folder actions don't quite work for me (on Mac OS 10.5.7) and I don't own a license to Hazel.

setWeblocThumb is written in Objective-C and C, using the OS X Cocoa and Carbon APIs. It is licensed under the Apache License version 2.0 and requires Mac OS 10.5 (Leopard) or later.
