NAME

Net::DHCP::Windows::Netsh::Parse - Parses the output from 'netsh dhcp server dump'

VERSION

Version 0.1.0

SYNOPSIS

    use Net::DHCP::Windows::Netsh::Parse;

    my $parser=Net::DHCP::Windows::Netsh::Parse->new;
    
    eval{
        $parser->parse( $dump );
    };
    if ( $@ ){
        print "It failed with... ".$@."\n";
    }
    
    # no white space
    my $json=$parser->json(0);
    
    # now with useful white space
    $json=$parser->json(0);

METHODS

new

This initiates the object.

No arguments are taken.

    my $parser=Net::DHCP::Windows::Netsh::Parse->new;

parse

This parses a dump from netsh.

Only one option is taken and that is a string.

Nothing is returned. It will die if it fails to parse.

    eval{
        $parser->parse( $dump );
    };
    if ( $@ ){
        print "It failed with... ".$@."\n";
    }

hash_ref

This returns the current hash reference for the parsed data.

    my $hash_ref=$parser->hash_ref;

json

This returns the parsed data as JSON.

One option is taken and that is either a 0/1 for if it should be made nice and pretty.

    # no white space
    my $json=$parser->json(0);
    
    # now with useful white space
    $json=$parser->json(0);

DATA STRUCTURE

The structure of it is as below for both the return hash ref or JSON.

   $hostname=>{$scope}=>{
                         $options=>{
                                     $option_id=>[]
                                    },
                         mask=>subnet mask,
                         desc=>description,
                        }

The $option_id will always be numeric, except for one special case, which is range. That option contains a array of ranges that the scope in question uses with in that subnet. Each item the array represents one range. The format is as below for the string.

    $start_ip $end_ip

Hostname will always have \\ removed, so \\winboot becomes just winboot.

$scope is going to be the base address of the subnet.

INTERNAL FUNCTIONS

add_options

This adds a option for a scope.

    $hostname = Hostname of the DHCP server.
    $scope = scope name
    $option = DHCP option integer
    $values = array ref of values

    $parser->( $hostname, $scope, $option, \@values );

add_scope

This adds a new scope.

    $hostname = Hostname of the DHCP server.
    $scope = scope name
    $mask = subnet mask for the scope
    $desc = description

    $parser->( $hostname, $scope, $mask, $desc );
