OK, since I started us down a dead-end path, here's some goodies that
DO work.
Create a new stack. Put the handlers below in the stack script.
Now create one large scrolling field.
Now run this in your message box, a lengthy shell task (finding all
html files in your Applications directory):
## RUN find /Applications/ -name '*.html as an asynchronous task and
stream the data back
put async_shell("find /Applications/ -name '*.html'") into tProcessID
repeat while async_process_alive(tProcessID)
put async_shell_get_data(tProcessID) into fld 1
wait 1 second with messages
end repeat
put async_shell_get_data(tProcessID) into fld 1
It could use a little polishing, but it works! Asynchronous shell tasks
on MacOS X...!
#######
global _async_shell_counter, _async_shell_map
function async_shell tCmd
if (_async_shell_counter is empty) then put 1 into
_async_shell_counter
else add 1 to _async_shell_counter
put specialFolderPath("temporary") into tFilePath
if (last char of tFilePath <> "/") then put "/" after tFilePath
put ("revTmp"&_async_shell_counter&".out") after tFilePath
put tCmd&" &> "&tFilePath&" & echo $!" into tCmd
put shell(tCmd) into tProcessID
put tFilePath into _async_shell_map[tProcessID]
return tProcessID
end async_shell
function async_process_alive tProcessID
put shell(("ps -p"&&tProcessID)) into tProcessList
return (offset(tProcessID, tProcessList) > 0)
end async_process_alive
function async_shell_get_data tProcessID
return url ("file:"&_async_shell_map[tProcessID])
end async_shell_get_data
Ugh. I just tried this and it doesn't work in Rev- although it's the
standard way to deal with this sort of task in a terminal.
I'm guessing that Rev refuses to return until the process is
completely terminated- and opens a whole new shell environment every
time you call shell(). How rude!
Now picking for a workaround... sorry for the false alarm.

Agh, sorry- I obviously missed the point of the thread.
Add an ampersand after your command:
get shell("mycommand > mylogfile.log &")
Voila, a "backgrounded" process that returns immediately.
Oh cool. I will go try it. I have a use for this. :)
