Rspec
Upon loading up the new release of OSX 10.5 (Leopard), I was very frustrated to find that Growl notifications no longer work when using
Autotest. Apparently growlnotify, the command line app which makes the magic happen, isn’t compatible. Read on to see how I got this work
It turns out that there is another way to get notifications into Growl other than the the (broken) growlnotify. That technique is to use Applescript.
Applescript allows you to do all sorts of neat things to applications in OSX but it is an arcane and hard to understand beast (at least in my
opinion – feel free to flame me 
). Based on a sample from the Growl website I was able to cobble together a working solution which
restores all the growlnotify goodness we have come to expect from Autotest. The first thing is to write the Applescript which talks to Growl.
Here is what I came up with (as modified from the Growl website)
— growlNotify.applescript
–
— Created by Mike Hagedorn on 2007-10-31.
— Copyright (c) 2007 Silverchair Solutions. All rights reserved. http://www.silverchairsolutions.com
— based on script from the growl website
— works around the fact that growlnotify doesnt work on leopard
— pass in like osascript growlNotify.applescript
<message> <image><br />
on run argv<br />
set rspec<em>title to item 1 of argv<br />
set rspec</em>message to item 2 of argv<br />
set rspec<em>image to item 3 of argv</p>
<p> tell application “GrowlHelperApp”<br />
— Make a list of all the notification types<br />
— that this script will ever send:<br />
set the allNotificationsList to ¬<br />
{”RSpec Notification” }</p>
<p> — Make a list of the notifications<br />
— that will be enabled by default.<br />
— Those not enabled by default can be enabled later<br />
— in the ‘Applications’ tab of the growl prefpane.<br />
set the enabledNotificationsList to ¬<br />
{”RSpec Notification”}</p>
<p> — Register our script with growl.<br />
— You can optionally (as here) set a default icon<br />
— for this script’s notifications.<br />
register as application “Growl-RSpec AppleScript Notifications” ¬<br />
all notifications allNotificationsList ¬<br />
default notifications enabledNotificationsList ¬<br />
icon of application “Script Editor”</p>
<p> — Send a Notification…<br />
notify with name “RSpec Notification” ¬<br />
title rspec</em>title ¬<br />
description rspec<em>message ¬<br />
application name “Growl-RSpec AppleScript Notifications” ¬<br />
image from location rspec</em>image</p>
<p> end tell</p>
<p> end run</p>
<p>Put this file somewhere where you can find it (I used ~/Library/Scripts/growlNotify.applescript) then modify the .autotest file you have in your home directory<br />
to not call growlnotify, but the new method you just crafted (i.e. the applescript). Here is what mine looks like</p>
<p> #<br />
# .autotest<br />

<p>Hey, the html mangled both of the scripts, and I never really used such a complex .autotest script, but the applescript works flawlessly after some character replacement. I put it in pasties:</p>
<p>growlnotify.scpt – <a href="http://pastie.caboo.se/112911" rel="nofollow">http://pastie.caboo.se/112911</a>

<p>Thanks for the tip, Mike? I wanted to ask if you did a clean install or an upgrade to 10.5? Growlnotify did not work for me after my upgrade but I quickly found out that the upgrade had dropped my /usr/local/bin path out of my $PATH…</p>

<p>Hi, I came up with another solution, a 1 line wrapper, no applescript… please tell me if it does not cover your needs, I may be missing your point here, or some aspects of it <img src='http://www.silverchairsolutions.com/blog/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>
<ul>
<li><p>In the growl prefs pane, network tab, activate incoming connections</p></li>
<li><p>rename /usr/local/bin/growlnotify to /usr/local/bin/growlnotify.wrapped</p></li>
<li><p>create /usr/local/bin/growlnotify as a shell script containing “exec /usr/local/bin/growlnotify.wrapped -H localhost ${1+$@}”</p></li>
</ul>
<p>This forces growlnotify to use the network to communicate with growl. (The script could also check that it is not already invoked with the “-H” option, I just did not need to care, maybe you would.)</p>
<p>Cheers</p>
