in reply to Stopping hanging commands (evals) within debugger

Just wrap your string eval in a block eval in which you set a %SIG{ INT } = sub{ die; }; ie:

eval { local $SIG{ INT } = sub{die}; eval $_code };

If you also want to be able to break out of long-running opcodes, you'd have to look at setting local $ENV{ PERL_SIGNALS } = 'unsafe';.

    Excellent, testscript works fine! =)

    $|=1; $_code=' sleep 1, print for (1..100)'; eval { local $SIG{ INT } = sub{die;}; eval $_code }; print "after interrupt"; eval $_code; # again w/o wrapper

    I'll post again when I got it integrated within the debugger!

    Cheers Rolf
