Re: eval-ling code in another process

Then how do I know if $? is the custom exception I have been looking for? All I get is WEXITSTATUS($?)=255 for any 'die' signal.

Consider replacing `die "Something informative";` [download] with `warn "Something informative"; exit $customCodeToDetectInParent;` [download] -- use JAPH; print JAPH::asString();	[reply] [d/l] [select]

die only writes its "exception" to the standard error stream, so you'll need to capture that output. In Unix you can do this using a piped open like `open my $fh, 'othercommand 2>&1 \|';` and then reading $fh. Or you could even do my $response = `othercommand 2>&1`; and parse out the result. Not sure if that works in Windows. You could also try IPC::Open3. I don't think Win32::Process will let you capture that.	[reply] [d/l] [select]
