NAME

    WWW::YaCyBlacklist - a Perl module to parse and execute YaCy blacklists

VERSION

    version 0.7.0

SYNOPSIS

        use WWW::YaCyBlacklist;
    
        my $ycb = WWW::YaCyBlacklist->new( { 'use_regex' => 1 } );
        $ycb->read_from_array(
            'test1.co/fullpath',
            'test2.co/.*',
        );
        $ycb->read_from_files(
            '/path/to/1.black',
            '/path/to/2.black',
        );
    
        print "Match!" if $ycb->check_url( 'http://test1.co/fullpath' );
        my @urls = (
            'https://www.perlmonks.org/',
            'https://metacpan.org/',
        );
        my @matches = $ycb->find_matches( @urls );
        my @nonmatches = $ycb->find_non_matches( @urls );
    
        $ycb->sortorder( 1 );
        $ycb->sorting( 'alphabetical' );
        $ycb->filename( '/path/to/new.black' );
        $ycb->store_list( );

METHODS

 new(%options)

 use_regex => 0|1 (default 1)

    Can only be set in the constructor and never be changed any later. If
    false, the pattern will not get checked if the host part is a regular
    expression (but the patterns remain in the list).

 filename => '/path/to/file.black' (default ycb.black)

    This is the file printed by store_list

 sortorder => 0|1 (default 0)

    0 ascending, 1 descending Configures sort_list

 sorting => 'alphabetical|length|origorder|random|reverse_host' (default
 'origorder)

    Configures sort_list

 void read_from_array( @patterns )

    Reads a list of YaCy blacklist patterns.

 void read_from_files( @files )

    Reads a list of YaCy blacklist files.

 int length( )

    Returns the number of patterns in the current list.

 bool check_url( $URL )

    1 if the URL was matched by any pattern, 0 otherwise.

 @URLS_OUT find_matches( @URLS_IN )

    Returns all URLs which was matches by the current list.

 @URLS_OUT find_non_matches( @URLS_IN )

    Returns all URLs which was not matches by the current list.

 void delete_pattern( $pattern )

    Removes a pattern from the current list.

 @patterns sort_list( )

    Returns a list of patterns configured by sorting and sortorder.

 void store_list( )

    Prints the current list to a file. Executes sort_list( ).

OPERATIONAL NOTES

    WWW::YaCyBlacklist checks the path part including the leading separator
    /. This protects against regexp compiling errors with leading
    quantifiers. So do not something like host.tld/^path although YaCy
    allows this.

    check_url( ) alway returns true if the protocol of the URL is not
    https? or ftps?.

BUGS

    YaCy does not allow host patterns with two ore more stars at the time
    being. WWW::YaCyBlacklist does not check for this but simply executes.
    This is rather a YaCy bug.
