NAME

OpenGuides::Utils - General utility methods for OpenGuides scripts.

DESCRIPTION

Provides general utility methods for OpenGuides scripts. Distributed and installed as part of the OpenGuides project, not intended for independent installation. This documentation is probably only useful to OpenGuides developers.

SYNOPSIS

use OpenGuide::Config;
use OpenGuides::Utils;

my $config = OpenGuides::Config->new( file => "wiki.conf" );
my $wiki = OpenGuides::Utils->make_wiki_object( config => $config );

METHODS

make_wiki_object
my $config = OpenGuides::Config->new( file => "wiki.conf" );
my $wiki = OpenGuides::Utils->make_wiki_object( config => $config );

Croaks unless an OpenGuides::Config object is supplied. Returns a Wiki::Toolkit object made from the given config file on success, croaks if any other error occurs.

The config file needs to define at least the following variables:

get_wgs84_coords

Returns coordinate data suitable for use with Google Maps (and other GIS systems that assume WGS-84 data).

my ($wgs84_long, $wgs84_lat) = OpenGuides::Utils->get_wgs84_coords(
                                    longitude => $longitude,
                                    latitude => $latitude,
                                    config => $config
                               );
get_wgs84_min_max

Given a set of WGS84 coordinate data, returns the minimum, maximum, and centre latitude and longitude.

%data = OpenGuides::Utils->get_wgs84_min_max(
    nodes => [
               { wgs84_lat => 51.1, wgs84_long => 1.1 },
               { wgs84_lat => 51.2, wgs84_long => 1.2 },
             ]
);
print "Top right-hand corner is $data{max_lat}, $data{max_long}";
print "Centre point is $data{centre_lat}, $data{centre_long}";

The hashes in the nodes argument can include other key/value pairs; these will just be ignored.

Returns false if it can't find any valid geodata in the nodes.

get_index_page_description
$tt_vars{page_description} =
    OpenGuides::Utils->get_index_page_description(
        format => "map",
        criteria => [ type => "locale", value => "croydon" ],
);

Returns a sentence that can be used as a summary of what's shown on an index page.

detect_redirect
$redir = OpenGuides::Utils->detect_redirect( content => "foo" );

Checks the content of a node to see if the node is a redirect to another node. If so, returns the name of the node that this one redirects to. If not, returns false.

(Also returns false if no content is provided.)

validate_edit
my $fails = OpenGuides::Utils->validate_edit(
    id       => $node,
    cgi_obj  => $q
);

Checks supplied content for general validity. If anything is invalid, returns an array ref of errors to report to the user.

parse_change_comment
my $change_comment = parse_change_comment($string, $base_url);

Given a base URL (for example, http://example.com/wiki.cgi?), takes a string, replaces [[page]] and [[page|titled link]] with

<a href="http://example.com/wiki.cgi?page">page</a>

and

<a href="http://example.com/wiki.cgi?page">titled link</a>

respectively, and returns it. This is a limited subset of wiki markup suitable for use in page change comments.

send_email
eval { OpenGuides::Utils->send_email(
        config        => $config,
        subject       => "Subject",
        body          => "Test body",
        admin         => 1,
        nobcc         => 1,
        return_output => 1
) };

if ($@) {
    print "Error mailing admin: $@\n";
} else {
    print "Mailed admin\n";
}

Send out email. If admin is true, the email will be sent to the site admin. If to is defined, email will be sent to addresses in that arrayref. If nobcc is true, there will be no Bcc to the admin.

subject and body are mandatory arguments.

Debugging: if return_output is true, the message will be returned as a string instead of being sent by email.

in_moderate_whitelist
if (OpenGuides::Utils->in_moderate_whitelist( '127.0.0.1' )) {
    # skip moderation and apply new verson to published site
}

Admins can supply a comma separated list of IP addresses or CIDR-notation subnets indicating the hosts which can bypass enforced moderation. Any values which cannot be parsed by NetAddr::IP will be ignored.
