Default is the opposite value of $public. * @type bool $publicly_queryable Whether queries can be performed on the front end for the post type * as part of parse_request().

Default is value of $public. * @type bool|string $show_in_menu Where to show the post type in the admin menu. To work, $show_ui * must be true. If true, the post type is shown in its own top level * menu. If false, no menu is shown.

Core features include 'title', * 'editor', 'comments', 'revisions', 'trackbacks', 'author', 'excerpt', * 'page-attributes', 'thumbnail', 'custom-fields', and 'post-formats'. * Additionally, the 'revisions' feature dictates whether the post type * will store revisions, the 'autosave' feature dictates whether the post type * will be autosaved, and the 'comments' feature dictates whether the * comments count will show on the edit screen. For backward compatibility reasons, * adding 'editor' support implies 'autosave' support too. A feature can also be * specified as an array of arguments to provide additional information * about supporting that feature. * Example: `array( 'my_feature', array( 'field' => 'value' ) )`. * If false, no features will be added. * Default is an array containing 'title' and 'editor'. * @type callable $register_meta_box_cb Provide a callback function that sets up the meta boxes for the * edit form. Do remove_meta_box() and add_meta_box() calls in the * callback. Default null. * @type string[] $taxonomies An array of taxonomy identifiers that will be registered for the * post type.

Default true. * @type int $ep_mask Endpoint mask to assign. If not specified and permalink_epmask is set, * inherits from $permalink_epmask. If not specified and permalink_epmask * is not set, defaults to EP_PERMALINK. * } * @type string|bool $query_var Sets the query_var key for this post type. Defaults to $post_type * key.

This could be used to check whether you need * to initialize an option during installation of a plugin, however that * can be done better by using add_option() which will not overwrite * existing options. * * Not initializing an option and using boolean `false` as a return value * is a bad practice as it triggers an additional database query. * * The type of the returned value can be different from the type that was passed * when saving or updating the option. If the option value was serialized, * then it will be unserialized when it is returned. In this case the type will * be the same. For example, storing a non-scalar value like an array will * return the same array. * * In most cases non-string scalar and null values will be converted and returned * as string equivalents. * * Exceptions: * * 1. When the option has not been saved in the database, the `$default_value` value * is returned if provided. If not, boolean `false` is returned. * 2.
