This would eventually allow F-F-O-R to overcome some of File::Find::Rule inherent limitations, which are caused due to its reliance on File::Find. The interface of F-F-Object-Rule still remains pretty much backwards compatible to that of F-F-Rule, but some stuff (like "->start()" and "->match()") have become much saner.

Rather than having to use plugin filters, I'd rather just write my own if necessary. So I wrote File::Next. use File::Next; my $iter = File::Next::files( { file_filter => sub { /\.pl$/ }, descend_filter => sub { $_ ne '.svn' }, }, '.', '../SomeDir' ); while ( my $file = $iter->() ) { print "$file\n"; } Like your previous example, that finds all .pl files under . and ../SomeDir, without looking into the .svn directories.

use File::Next;

my $iter =
File::Next::files( {
file_filter => sub { /\.pl$/ },
descend_filter => sub { $_ ne '.svn' },
}, '.', '../SomeDir' );

while ( my $file = $iter->() ) {
print "$file\n";
}

Like your previous example, that finds all .pl files under . and ../SomeDir, without looking into the .svn directories.
