Re: [MacPerl] Unix daemons in Perl on MacOS?

[Enrique Terrazas <terrazas@pangloss.ucsf.EDU>]

hello,

while not a MacPerl only solution, how about a stay open applescript that
calls a MacPerl script?  The example is a script that sleeps for 5 seconds,
then does something.  A stay open applescript can call a perl script every
5 seconds.  For user feedback, Mac::PerlAnswer is ok, but there is no built
in timeout for the dialog.  As of OS9, the applescript display dialog has
an option "giving up after" x seconds, which can be called using Mac::Glue.
 Just a thought.
