use the 'preprocess ' option.
Your other option is to mess with signals (see
perlsig, %SIG)
#!/usr/bin/perl -w
use strict;
use File::Find;
# scrap codeee
find( { wanted => \&wanted,
# preprocess => \&preprocess,
}, '/' );
BEGIN { use vars qw( $maxHit $Hit); $maxHit = 10; }
BEGIN { $SIG{__DIE__} = sub {
my @d = @_;
if($d[-1] eq "dying max $maxHit") {
warn "hit the max $maxHit";
return();
} else {
warn(@_);
exit(1);
}
};
}
sub wanted {
my $file = $_;
print "$file\n";
$Hit++;
die "dying max $maxHit" if($Hit >= $maxHit)
}
## something like this
sub preprocess {
my @list = @_;
my $diff = $maxHit - $Hit;
warn "pre processing( $Hit, $maxHit, ".scalar(@list)." )";
if($Hit > $maxHit ) {
return ();
}elsif( @list > $diff ) {
warn "splicing";use Data::Dumper;
@list = splice(@list,0,$diff);
warn Dumper \@list;
}
return @list;
}
update: you better stick with the eval ( see
Kanjis node above). I've been too signal happy lately ;)
update: please note that the preprocess option is not available everywhere (best upgrade File::Find)
I also feel that there ought to exist File::Find::breakout, which would basically stop find from executing anymore (return? ;)
UPDATE:
after hastily posting this, which i still think is good idea, a couple of smart asses point out goto. Yeah well i'm not 0 for 2 so far ;)(dammit! sometimes solutions you know but don't love escape you)
