Hi, whats the right way to precompile a regular expression that gets used multiple
times without changing.
I don't think I can use /o, because the specific line of code which performs the
pattern match is used to check various patterns against various values at various
times. None the less, the patterns themselves don't change, once established, and it
seems I should be able to save a precompiled regular expression in a variable and use
it when it's time to match the corresponding pattern.
The code as it stands looks like this:
if( defined($addr) and $addr =~ /$self->{_rule}/i ) {
$retval = $self->{_confidence};
}
which is an object method used with multiple object instances each having its own
value for $self->{_rule}, which is why I can't use /o.
Any help very much appreciated, and yes I am now rereading the documentation.
