Waiting for an Application to launch

I use an AppleScript to implement “Open Terminal Here” functionality on my Macs, and just now I noticed on the Intel machine it had stopped working properly if Terminal wasn’t already running. For some reason, on PPC it still sends the message through, but on x86 it doesn’t. So, I had to use the following code to get it to work if Terminal wasn’t already running, which can be generalised to any application: repeat while "Terminal" is not in name of processes delay 0.5 end repeat The whole script, which can be saved as an application bundle, set to not show in dock, and then placed in the Toolbar:
1 -- when the toolbar script icon is clicked
2 --
3 on run
4 tell application "Finder"
5 activate
6 try
7 set this_folder to (the target of the front window) as alias
8 --display dialog POSIX path of this_folder
9 on error
10 set this_folder to startup disk as alias
11 end try
12 my process_item(this_folder)
13 end tell
14 end run
15
16
17
18 -- This handler processes folders dropped onto the toolbar script icon
19 --
20 on open these_items
21 repeat with i from 1 to the count of these_items
22 set this_item to item i of these_items
23 my process_item(this_item)
24 end repeat
25 end open
26
27
28 -- this subroutine processes does the actual work
29 --
30 on process_item(this_item)
31 tell application "System Events"
32 try
33 get process "Terminal"
34
35 tell application "Terminal"
36 activate
37 do script "cd " & (quoted form of POSIX path of this_item)
38 end tell
39 on error -- Terminal Not running, launch and run in first window.
40 launch application "Terminal"
41 -- May need to wait until Terminal finishes launching
42 repeat while "Terminal" is not in name of processes
43 delay 0.5
44 end repeat
45 tell application "Terminal"
46 activate
47 -- So we don't create a new window: in window 1
48 do script "cd " & (quoted form of POSIX path of this_item) in window 1
49 end tell
50 end try
51 end tell
52 end process_item
