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:

           ·   dbtype - one of "postgres", "mysql" and "sqlite"

           ·   dbname

           ·   indexing_directory - for the Search::InvertedIndex, Plucene, or "Lucy" files to go
               in

       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.
