NAME

       OpenGuides::Template - Do Template Toolkit related stuff for OpenGuides applications.

DESCRIPTION

       Does all the Template Toolkit stuff for OpenGuides.  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 OpenGuides::Config;
         use OpenGuides::Utils;
         use OpenGuides::Template;

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

         print OpenGuides::Template->output( wiki     => $wiki,
                                             config   => $config,
                                             template => "node.tt",
                                             vars     => { foo => "bar" }
         );

METHODS

       output
             print OpenGuides::Template->output( wiki         => $wiki,
                                                 config       => $config,
                                                 template     => "node.tt",
                                                 content_type => "text/html",
                                                 cookies      => $cookie,
                                                 vars         => {foo => "bar"},
                                                 noheaders    => 1
             );

           Returns everything you need to send to STDOUT, including the Content-Type: header. Croaks unless
           "template" is supplied.

           The config object and variables supplied in "vars" are passed through to the template specified.
           Additional Template Toolkit variables are automatically set and passed through as well, as described
           below.  Note: variables set in "vars" will over-ride any variables of the same name in the config
           object or the user cookies.

           •   "openguides_version"

           •   "site_name"

           •   "cgi_url"

           •   "full_cgi_url"

           •   "enable_page_deletion" (gets set to true or false - defaults to false)

           •   "contact_email"

           •   "stylesheet"

           •   "home_link"

           •   "formatting_rules_link" (unless "omit_formatting_link" is set in user cookie)

           •   "navbar_on_home_page"

           •   "home_name"

           •   "gmaps_api_key"

           •   "licence_name"

           •   "licence_url"

           •   "licence_info_url"

           •   "prefs" (the preferences from the user cookie)

           If "node" is supplied:

           •   "node_name"

           •   "node_param" (the node name escaped for use in URLs)

           Content-Type: defaults to "text/html" and is omitted if the "content_type" arg is explicitly set to
           the blank string.

           However, what you more often need is the "noheaders" option, which suppresses all HTTP headers, not
           just the Content-Type.

           The HTTP response code may be explictly set with the "http_status" arg.

       extract_metadata_vars
             my %node_data = $wiki->retrieve_node( "Home Page" );

             my %metadata_vars = OpenGuides::Template->extract_metadata_vars(
                                     wiki     => $wiki,
                                     config   => $config,
                                     metadata => $node_data{metadata}
                                 );

             # -- or --

             my %metadata_vars = OpenGuides::Template->extract_metadata_vars(
                                     wiki     => $wiki,
                                     config   => $config,
                                     cgi_obj  => $q
                                 );

             # -- then --

             print OpenGuides::Template->output(
                       wiki     => $wiki,
                       config   => $config,
                       template => "node.tt",
                       vars     => { foo => "bar",
                                     %metadata_vars }
                   );

           Picks out things like categories, locales, phone number etc from EITHER the metadata hash returned by
           Wiki::Toolkit OR the query parameters in a CGI object, and packages them nicely for passing to
           templates or storing in Wiki::Toolkit datastore.  If you supply both "metadata" and "cgi_obj" then
           "metadata" will take precedence, but don't do that.

           The variables "dist_field", "coord_field_1", "coord_field_1_name", "coord_field_1_value",
           "coord_field_2", "coord_field_2_name", and "coord_field_2_value", which are used to create various
           forms, will only be set if either "metadata" is supplied or "set_coord_field_vars" is true, to
           prevent these values from being stored in the database on a node commit.
