Perl Term::ReadLine::Gnu Signal Handling Difficultiesby sgt_b2002 (Initiate)
|on Nov 12, 2012 at 20:00 UTC||Need Help??|
sgt_b2002 has asked for the
wisdom of the Perl Monks concerning the following question:
I'm using Term::ReadLine::Gnu and have run into a problem with signal handling. Given the script below and a TERM signal sent to the script, the handler for the TERM signal is not triggered until after the enter key is pressed. Using Term::ReadLine:Perl this does not occur.
I've read that Term::ReadLine::Gnu has its own internal signal handlers, but frankly I'm at a loss as to how to work with them.
I've reviewed the Gnu_Variables and tried setting the rl_catch_signals variable to 0, but that didn't help. Ideally, I'd like to work with the Gnu signal handlers, but I'll settle for disabling them too.
To be absolutely specific, I need the TERM handler to trigger after the signal is received instead of waiting for the enter key to be pressed.
Any help or advice is very much appreciated!
