/**
* Abilities API: core functions for registering and managing abilities.
*
* The Abilities API provides a unified, extensible framework for registering
* and executing discrete capabilities within WordPress. An "ability" is a
* self-contained unit of functionality with defined inputs, outputs, permissions,
* and execution logic.
*
* ## Overview
*
* The Abilities API enables developers to:
*
* - Register custom abilities with standardized interfaces.
* - Define permission checks and execution callbacks.
* - Organize abilities into logical categories.
* - Validate inputs and outputs using JSON Schema.
* - Expose abilities to clients such as the REST API.
*
* ## Working with Abilities
*
* Abilities must be registered on the `wp_abilities_api_init` action hook.
* Attempting to register an ability outside of this hook will fail and
* trigger a `_doing_it_wrong()` notice.
* Example:
*
* function my_plugin_register_abilities(): void {
* wp_register_ability(
* 'my-plugin/export-users',
* array(
* 'label' => __( 'Export Users', 'my-plugin' ),
* 'description' => __( 'Exports user data to CSV format.', 'my-plugin' ),
* 'category' => 'data-export',
* 'execute_callback' => 'my_plugin_export_users',
* 'permission_callback' => function(): bool {
* return current_user_can( 'export' );
* },
* 'input_schema' => array(
* 'type' => 'string',
* 'enum' => array( 'subscriber', 'contributor', 'author', 'editor', 'administrator' ),
* 'description' => __( 'Limits the export to users with this role.', 'my-plugin' ),
* 'required' => false,
* ),
* 'output_schema' => array(
* 'type' => 'string',
* 'description' => __( 'User data in CSV format.', 'my-plugin' ),
* 'required' => true,
* ),
* 'meta' => array(
* 'public' => true,
* ),
* )
* );
* }
* add_action( 'wp_abilities_api_init', 'my_plugin_register_abilities' );
*
* Once registered, abilities can be checked, retrieved, and managed:
*
* // Checks if an ability is registered, and prints its label.
* if ( wp_has_ability( 'my-plugin/export-users' ) ) {
* $ability = wp_get_ability( 'my-plugin/export-users' );
*
* echo $ability->get_label();
* }
*
* // Gets all registered abilities.
* $all_abilities = wp_get_abilities();
*
* // Unregisters when no longer needed.
* wp_unregister_ability( 'my-plugin/export-users' );
*
* ## Best Practices
*
* - Always register abilities on the `wp_abilities_api_init` hook.
* - Use namespaced ability names to prevent conflicts.
* - Implement robust permission checks in permission callbacks.
* - Provide an `input_schema` to ensure data integrity and document expected inputs.
* - Define an `output_schema` to describe return values and validate responses.
* - Return `WP_Error` objects for failures rather than throwing exceptions.
* - Use internationalization functions for all user-facing strings.

/**
* Registers a new ability using the Abilities API. It requires three steps:
*
* 1. Hook into the `wp_abilities_api_init` action.
* 2. Call `wp_register_ability()` with a namespaced name and configuration.
* 3. Provide execute and permission callbacks.
*
* Example:
*
* function my_plugin_register_abilities(): void {
* wp_register_ability(
* 'my-plugin/analyze-text',
* array(
* 'label' => __( 'Analyze Text', 'my-plugin' ),
* 'description' => __( 'Performs sentiment analysis on provided text.', 'my-plugin' ),
* 'category' => 'text-processing',
* 'input_schema' => array(
* 'type' => 'string',
* 'description' => __( 'The text to be analyzed.', 'my-plugin' ),
* 'minLength' => 10,
* 'required' => true,
* ),
* 'output_schema' => array(
* 'type' => 'string',
* 'enum' => array( 'positive', 'negative', 'neutral' ),
* 'description' => __( 'The sentiment result: positive, negative, or neutral.', 'my-plugin' ),
* 'required' => true,
* ),
* 'execute_callback' => 'my_plugin_analyze_text',
* 'permission_callback' => 'my_plugin_can_analyze_text',
* 'meta' => array(
* 'annotations' => array(
* 'readonly' => true,
* ),
* 'public' => true,
* ),
* )
* );
* }
* add_action( 'wp_abilities_api_init', 'my_plugin_register_abilities' );
*
* ### Naming Conventions
*
* Ability names must follow these rules:
*
* - Include a namespace prefix (e.g., `my-plugin/my-ability`).
* - Use only lowercase alphanumeric characters, dashes, and forward slashes.
* - Use descriptive, action-oriented names (e.g., `process-payment`, `generate-report`).
*
* ### Categories
*
* Abilities must be organized into categories. Ability categories provide better
* discoverability and must be registered before the abilities that reference them:
*
* function my_plugin_register_categories(): void {
* wp_register_ability_category(
* 'text-processing',
* array(
* 'label' => __( 'Text Processing', 'my-plugin' ),
* 'description' => __( 'Abilities for analyzing and transforming text.', 'my-plugin' ),
* )
* );
* }
* add_action( 'wp_abilities_api_categories_init', 'my_plugin_register_categories' );
*
* ### Input and Output Schemas
*
* Schemas define the expected structure, type, and constraints for ability inputs
* and outputs using JSON Schema syntax. They serve two critical purposes: automatic
* validation of data passed to and returned from abilities, and self-documenting
* API contracts for developers.
*
* WordPress implements a validator based on a subset of the JSON Schema Version 4
* specification (https://json-schema.org/specification-links.html#draft-4).
* For details on supported JSON Schema properties and syntax, see the
* related WordPress REST API Schema documentation:
* https://developer.wordpress.org/rest-api/extending-the-rest-api/schema/#json-schema-basics
*
* Defining schemas is mandatory when there is a value to pass or return.
* They ensure data integrity, improve developer experience, and enable
* better documentation:
*
* 'input_schema' => array(
* 'type' => 'string',
* 'description' => __( 'The text to be analyzed.', 'my-plugin' ),
* 'minLength' => 10,
* 'required' => true,
* ),
* 'output_schema' => array(
* 'type' => 'string',
* 'enum' => array( 'positive', 'negative', 'neutral' ),
* 'description' => __( 'The sentiment result: positive, negative, or neutral.', 'my-plugin' ),
* 'required' => true,
* ),
*
* ### Callbacks
*
* #### Execute Callback
*
* The execute callback performs the ability's core functionality. It receives
* optional input data and returns either a result or `WP_Error` on failure.
*
* function my_plugin_analyze_text( string $input ): string|WP_Error {
* $score = My_Plugin::perform_sentiment_analysis( $input );
* if ( is_wp_error( $score ) ) {
* return $score;
* }
* return My_Plugin::interpret_sentiment_score( $score );
* }
*
* #### Permission Callback
*
* The permission callback determines whether the ability can be executed.
* It receives the same input as the execute callback and must return a
* boolean or `WP_Error`. Common use cases include checking user capabilities,
* validating API keys, or verifying system state:
*
* function my_plugin_can_analyze_text( string $input ): bool|WP_Error {
* return current_user_can( 'edit_posts' );
* }
*
* ### Client Exposure
*
* Set the high-level `public` flag to make an ability available to clients
* such as the REST API, MCP, or AI agents:
*
* 'meta' => array(
* 'public' => true,
* ),
*
* The `public` flag seeds the default for each per-channel flag. For the REST
* API it seeds `show_in_rest`, which lets the ability be invoked via HTTP
* requests. Set a per-channel flag directly to override that default. For
* example, keep a public ability out of the REST API:
*
* 'meta' => array(
* 'public' => true,
* 'show_in_rest' => false,
* ),
*
* @since 6.9.0
*
* @see WP_Abilities_Registry::register()
* @see wp_register_ability_category()
* @see wp_unregister_ability()
*
* @param string $name The name of the ability. Must be a namespaced string containing
* a prefix, e.g., `my-plugin/my-ability`. Can only contain lowercase
* alphanumeric characters, dashes, and forward slashes.
* @param array<string, mixed> $args {
* An associative array of arguments for configuring the ability.
*
* @type string $label Required. The human-readable label for the ability.
* @type string $description Required. A detailed description of what the ability does
* and when it should be used.
* @type string $category Required. The ability category slug this ability belongs to.
* The ability category must be registered via `wp_register_ability_category()`
* before registering the ability.
* @type callable $execute_callback Required. A callback function to execute when the ability is invoked.
* Receives optional mixed input data and must return either a result
* value (any type) or a `WP_Error` object on failure.
* @type callable $permission_callback Required. A callback function to check permissions before execution.
* Receives optional mixed input data (same as `execute_callback`) and
* must return `true`/`false` for simple checks, or `WP_Error` for
* detailed error responses.
* @type array<string, mixed> $input_schema Optional. JSON Schema definition for validating the ability's input.
* Must be a valid JSON Schema object defining the structure and
* constraints for input data. Used for automatic validation and
* API documentation.
* @type array<string, mixed> $output_schema Optional. JSON Schema definition for the ability's output.
* Describes the structure of successful return values from
* `execute_callback`. Used for documentation and validation.
* @type array<string, mixed> $meta {
* Optional. Additional metadata for the ability.
*
* @type array<string, bool|null> $annotations {
* Optional. Semantic annotations describing the ability's behavioral characteristics.
* These annotations are hints for tooling and documentation.
*
* @type bool|null $readonly Optional. If true, the ability does not modify its environment.
* @type bool|null $destructive Optional. If true, the ability may perform destructive updates to its environment.
* If false, the ability performs only additive updates.
* @type bool|null $idempotent Optional. If true, calling the ability repeatedly with the same arguments
* will have no additional effect on its environment.
* }
* @type bool $public Optional. Whether the ability is meant to be available to
* clients such as the REST API, MCP, or AI agents. Seeds
* the default for per-channel flags like `$show_in_rest`.
* Defaults to false.
* @type bool $show_in_rest Optional. Whether to expose this ability in the REST API.
* When true, the ability can be invoked via HTTP requests.
* Default is the value of `$public` when set, false otherwise.
* }
* @type string $ability_class Optional. Fully-qualified custom class name to instantiate
* instead of the default `WP_Ability` class. The custom class
* must extend `WP_Ability`. Useful for advanced customization
* of ability behavior.
* }
* @return WP_Ability|null The registered ability instance on success, `null` on failure.

/**
* Retrieves registered abilities, optionally filtered by the given arguments.
*
* When called without arguments, returns all registered abilities. When called

*
* Filtering pipeline (executed in order):
*
* 1. Declarative filters (`category`, `namespace`, `meta`) — per-item, AND logic between
* arg types.
* 2. `item_include_callback` — per-item, caller-scoped. Return true to include, false to exclude.
* 3. `wp_get_abilities_item_include` filter — per-item, ecosystem-scoped. Plugins can enforce
* universal inclusion rules regardless of what the caller passed.
* 4. `result_callback` — on the full matched array, caller-scoped. Sort, slice, or reshape.
* 5. `wp_get_abilities_result` filter — on the full array, ecosystem-scoped.
*
* Steps 1–3 run inside a single loop over the registry — no extra iteration.
*
* Examples:
*
* // All abilities (unchanged behaviour).
* $abilities = wp_get_abilities();
*
* // Filter by category.
* $abilities = wp_get_abilities( array( 'category' => 'content' ) );
*
* // Filter by namespace.
* $abilities = wp_get_abilities( array( 'namespace' => 'woocommerce' ) );
*
* // Filter by meta.
* $abilities = wp_get_abilities( array( 'meta' => array( 'show_in_rest' => true ) ) );
*
* // Combine filters (AND logic between arg types).
* $abilities = wp_get_abilities( array(
* 'category' => 'content',
* 'namespace' => 'core',
* 'meta' => array( 'show_in_rest' => true ),
* ) );
*
* // Caller-scoped per-item callback.
* $abilities = wp_get_abilities( array(
* 'item_include_callback' => function ( WP_Ability $ability ) {
* return current_user_can( 'manage_options' );
* },
* ) );
*
* // Caller-scoped result callback (sort + paginate).
* $abilities = wp_get_abilities( array(
* 'result_callback' => function ( array $abilities ) {
* usort( $abilities, fn( $a, $b ) => strcasecmp( $a->get_label(), $b->get_label() ) );
* return array_slice( $abilities, 0, 10 );
* },
* ) );
*
* The pipeline always runs, even when called with no arguments. This ensures that the
* `wp_get_abilities_item_include` and `wp_get_abilities_result` filters always fire,
* giving plugins a reliable place to enforce universal inclusion or shaping rules.
* For raw, unfiltered registry data that bypasses the filter pipeline entirely, use
* {@see WP_Abilities_Registry::get_all_registered()} directly.
*
* @since 6.9.0
* @since 7.1.0 Added the `$args` parameter for filtering support.

* @see WP_Abilities_Registry::get_all_registered()
*
* @param array $args {
* Optional. Arguments to filter the returned abilities. Default empty array (returns all).
*
* @type string $category Filter by category slug. Only abilities whose category
* exactly matches the given slug are included.
* @type string $namespace Filter by ability namespace prefix. Pass the namespace
* without a trailing slash, e.g. `'woocommerce'` matches
* `'woocommerce/create-order'`.
* @type array $meta Filter by meta key/value pairs. All conditions must
* match (AND logic). Supports nested arrays for structured
* meta, e.g. `array( 'mcp' => array( 'public' => true ) )`.
* @type callable $item_include_callback Optional. A callback invoked per ability after declarative
* filters. Receives a WP_Ability instance, returns bool.
* Return true to include, false to exclude.
* @type callable $result_callback Optional. A callback invoked once on the full matched
* array. Receives WP_Ability[], must return WP_Ability[].
* Use for sorting, slicing, or reshaping the result.
* }

* keyed by ability name. Returns an empty array if no abilities are
* registered, the registry is unavailable, or no abilities match the

People searching for gerçek canlı casino usually mean live-dealer roulette, blackjack, baccarat, or game-show tables streamed from a studio with a real dealer, rather than an RNG-only game. To assess authenticity, verify the operator’s licence directly with the regulator, check the named game provider and studio, look for clear rules and table limits, inspect withdrawal terms, and confirm that the service is legal in your jurisdiction; a foreign licence does not automatically make an operator legal in Türkiye.

Oferty określane jako zagraniczne kasyna bonus bez depozytu mogą obejmować darmowe spiny lub niewielkie środki promocyjne przyznawane po rejestracji i weryfikacji konta. Przed skorzystaniem z promocji należy dokładnie sprawdzić wymagania obrotu, maksymalną wypłatę, czas ważności bonusu oraz ograniczenia dla użytkowników z Polski. Zagraniczna licencja nie legalizuje automatycznie działalności hazardowej w Polsce, dlatego warto zweryfikować operatora w oficjalnych źródłach i grać odpowiedzialnie .
