show working code will be little bit hard because I'm listening to sockets... but here is sth. that should at least show what I'm trying to do:
# $term is the socket
# $text contains all received and unscanned text
# $scanned contains all scanned text
my $time = gettimeofday();
# sth. to read?
if (read($term, $rec, 0xFFFF))
# collect what have been read
$text .= $rec;
# expression found?
if ($text =~ s/(.*)($expect)//s)
$scanned .= $1;
$scanned .= "MATCH";
$scanned .= $2;
# shorten string for speed up
elsif (length($text) >= 20)
$scanned .= "CUTTED";
$scanned .= substr($text, 0, length($text) - 20 + 1);
$text = substr($text, length($text) - 20 + 1);
if (gettimeofday() - $time > $timeout)
$scanned .= "TIMEOUT";
It seems that the "elsif (length($text) >= 20)" makes things faster but doesn't do exactly what I want because in this way I can lose possible matchings :(
