OpenGuides::JSON(3pm) User Contributed Perl Documentation OpenGuides::JSON(3pm) emit_json Renders the given node as JSON output_as_json Renders the given arbitary data as JSON NAME
OpenGuides::JSON - An OpenGuides plugin to output JSON. DESCRIPTION
Does all the JSON 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 Wiki::Toolkit; use OpenGuides::Config; use OpenGuides::JSON; my $wiki = Wiki::Toolkit->new( ... ); my $config = OpenGuides::Config->new( file => "wiki.conf" ); my $json_writer = OpenGuides::JSON->new( wiki => $wiki, config => $config ); # JSON version of a node. print "Content-Type: application/javascript "; print $json_writer->emit_json( node => "Masala Zone, N1 0NU" ); # Ten most recent changes. print "Content-Type: application/javascript "; print "Last-Modified: " . $self->json_timestamp( items => 10 ) . " "; print $json_writer->make_recentchanges_json( items => 10 ); METHODS
new my $json_writer = OpenGuides::JSON->new( wiki => $wiki, config => $config ); "wiki" must be a Wiki::Toolkit object and "config" must be an OpenGuides::Config object. Both arguments mandatory. emit_json $wiki->write_node( "Masala Zone, N1 0NU", "Quick and tasty Indian food", $checksum, { comment => "New page", username => "Kake", locale => "Islington" } ); print "Content-Type: application/javascript "; print $json_writer->emit_json( node => "Masala Zone, N1 0NU" ); Note: Some of the fields emitted by the JSON generator are taken from the node metadata. The form of this metadata is not mandated by Wiki::Toolkit. Your wiki application should make sure to store some or all of the following metadata when calling "write_node": postcode - The postcode or zip code of the place discussed by the node. Defaults to the empty string. city - The name of the city that the node is in. If not supplied, then the value of "default_city" in the config object supplied to "new", if available, otherwise the empty string. country - The name of the country that the node is in. If not supplied, then the value of "default_country" in the config object supplied to "new" will be used, if available, otherwise the empty string. username - An identifier for the person who made the latest edit to the node. This person will be listed as a contributor (Dublin Core). Defaults to empty string. locale - The value of this can be a scalar or an arrayref, since some places have a plausible claim to being in more than one locale. Each of these is put in as a "Neighbourhood" attribute. phone - Only one number supported at the moment. No validation. website - No validation. opening_hours_text - A freeform text field. json_maker Returns a raw Wiki::Toolkit::Plugin::JSON object created with the values you invoked this module with. make_recentchanges_json # Ten most recent changes. print "Content-Type: application/javascript "; print "Last-Modified: " . $json_writer->json_timestamp( items => 10 ) . " "; print $json_writer->make_recentchanges_json( items => 10 ); # All the changes made by bob in the past week, ignoring minor edits. my %args = ( days => 7, ignore_minor_edits => 1, filter_on_metadata => { username => "bob" }, ); print "Content-Type: application/javascript "; print "Last-Modified: " . $json_writer->json_timestamp( %args ) . " "; print $json_writer->make_recentchanges_json( %args ); json_timestamp print "Last-Modified: " . $json_writer->json_timestamp( %args ) . " "; Returns the timestamp of the RSS feed in POSIX::strftime style ("Tue, 29 Feb 2000 12:34:56 GMT"), which is equivalent to the timestamp of the most recent item in the feed. Takes the same arguments as make_recentchanges_json(). You will most likely need this to print a Last-Modified HTTP header so user-agents can determine whether they need to reload the feed or not.
