From 9b2f7635fd5f697f711638581d58cc05fa6306ac Mon Sep 17 00:00:00 2001 From: Andrey Subbota Date: Wed, 3 Dec 2025 14:10:50 +0100 Subject: [PATCH 01/45] Add API Model Layer for OpenAPI 3.x support Introduce version-agnostic DTO classes that serve as the foundation for supporting multiple OpenAPI versions (2.0, 3.0, 3.1). New classes added: - ApiModel::Spec - Root specification container - ApiModel::Info - API metadata - ApiModel::Server - Server definitions (OAS3) - ApiModel::PathItem - Path with operations - ApiModel::Operation - HTTP operation definitions - ApiModel::Parameter - Query/path/header parameters - ApiModel::RequestBody - Request body for OAS3 - ApiModel::Response - Response definitions - ApiModel::MediaType - Content-type wrappers - ApiModel::Schema - JSON Schema representation - ApiModel::SecurityScheme - Security definitions - ApiModel::Tag - Operation grouping - ApiModel::Components - Schema/security container Each class includes to_h and to_swagger2_h methods for version-specific output generation. --- lib/grape-swagger/api_model.rb | 23 +++ lib/grape-swagger/api_model/components.rb | 63 ++++++++ lib/grape-swagger/api_model/info.rb | 51 +++++++ lib/grape-swagger/api_model/media_type.rb | 27 ++++ lib/grape-swagger/api_model/operation.rb | 74 ++++++++++ lib/grape-swagger/api_model/parameter.rb | 134 ++++++++++++++++++ lib/grape-swagger/api_model/path_item.rb | 58 ++++++++ lib/grape-swagger/api_model/request_body.rb | 55 +++++++ lib/grape-swagger/api_model/response.rb | 105 ++++++++++++++ lib/grape-swagger/api_model/schema.rb | 104 ++++++++++++++ .../api_model/security_scheme.rb | 112 +++++++++++++++ lib/grape-swagger/api_model/server.rb | 46 ++++++ lib/grape-swagger/api_model/spec.rb | 101 +++++++++++++ lib/grape-swagger/api_model/tag.rb | 38 +++++ 14 files changed, 991 insertions(+) create mode 100644 lib/grape-swagger/api_model.rb create mode 100644 lib/grape-swagger/api_model/components.rb create mode 100644 lib/grape-swagger/api_model/info.rb create mode 100644 lib/grape-swagger/api_model/media_type.rb create mode 100644 lib/grape-swagger/api_model/operation.rb create mode 100644 lib/grape-swagger/api_model/parameter.rb create mode 100644 lib/grape-swagger/api_model/path_item.rb create mode 100644 lib/grape-swagger/api_model/request_body.rb create mode 100644 lib/grape-swagger/api_model/response.rb create mode 100644 lib/grape-swagger/api_model/schema.rb create mode 100644 lib/grape-swagger/api_model/security_scheme.rb create mode 100644 lib/grape-swagger/api_model/server.rb create mode 100644 lib/grape-swagger/api_model/spec.rb create mode 100644 lib/grape-swagger/api_model/tag.rb diff --git a/lib/grape-swagger/api_model.rb b/lib/grape-swagger/api_model.rb new file mode 100644 index 00000000..9761edd9 --- /dev/null +++ b/lib/grape-swagger/api_model.rb @@ -0,0 +1,23 @@ +# frozen_string_literal: true + +require_relative 'api_model/schema' +require_relative 'api_model/info' +require_relative 'api_model/server' +require_relative 'api_model/media_type' +require_relative 'api_model/parameter' +require_relative 'api_model/request_body' +require_relative 'api_model/response' +require_relative 'api_model/operation' +require_relative 'api_model/path_item' +require_relative 'api_model/security_scheme' +require_relative 'api_model/tag' +require_relative 'api_model/components' +require_relative 'api_model/spec' + +module GrapeSwagger + module ApiModel + # Version-agnostic API model for OpenAPI/Swagger specifications. + # This layer provides a unified representation that can be exported + # to Swagger 2.0, OpenAPI 3.0, or OpenAPI 3.1 formats. + end +end diff --git a/lib/grape-swagger/api_model/components.rb b/lib/grape-swagger/api_model/components.rb new file mode 100644 index 00000000..e7d05d66 --- /dev/null +++ b/lib/grape-swagger/api_model/components.rb @@ -0,0 +1,63 @@ +# frozen_string_literal: true + +module GrapeSwagger + module ApiModel + # Components container (OAS3) / Definitions container (Swagger 2.0). + class Components + attr_accessor :schemas, :responses, :parameters, :examples, + :request_bodies, :headers, :security_schemes, + :links, :callbacks, :extensions + + def initialize + @schemas = {} + @responses = {} + @parameters = {} + @examples = {} + @request_bodies = {} + @headers = {} + @security_schemes = {} + @links = {} + @callbacks = {} + @extensions = {} + end + + def add_schema(name, schema) + @schemas[name] = schema + end + + def add_security_scheme(name, scheme) + @security_schemes[name] = scheme + end + + def empty?

This enables clean conversion between spec formats. New builders: - SchemaBuilder - Creates Schema objects from type definitions - ParameterBuilder - Builds Parameter objects from route params - ResponseBuilder - Creates Response objects from route responses - OperationBuilder - Builds Operation objects from route definitions - SpecBuilder - Main entry point, builds complete Spec from Swagger hash The SpecBuilder.build_from_swagger_hash method enables gradual migration by converting existing Swagger 2.0 output to the API Model. --- lib/grape-swagger/model_builder.rb | 14 + .../model_builder/operation_builder.rb | 127 +++++++ .../model_builder/parameter_builder.rb | 88 +++++ .../model_builder/response_builder.rb | 88 +++++ .../model_builder/schema_builder.rb | 202 +++++++++++ .../model_builder/spec_builder.rb | 318 ++++++++++++++++++ 6 files changed, 837 insertions(+) create mode 100644 lib/grape-swagger/model_builder.rb create mode 100644 lib/grape-swagger/model_builder/operation_builder.rb create mode 100644 lib/grape-swagger/model_builder/parameter_builder.rb create mode 100644 lib/grape-swagger/model_builder/response_builder.rb create mode 100644 lib/grape-swagger/model_builder/schema_builder.rb create mode 100644 lib/grape-swagger/model_builder/spec_builder.rb diff --git a/lib/grape-swagger/model_builder.rb b/lib/grape-swagger/model_builder.rb new file mode 100644 index 00000000..d93e1af2 --- /dev/null +++ b/lib/grape-swagger/model_builder.rb @@ -0,0 +1,14 @@ +# frozen_string_literal: true + +require_relative 'model_builder/schema_builder' +require_relative 'model_builder/parameter_builder' +require_relative 'model_builder/response_builder' +require_relative 'model_builder/operation_builder' +require_relative 'model_builder/spec_builder' + +module GrapeSwagger + module ModelBuilder + # Model builders convert Grape routes and Swagger hashes to ApiModel objects. + # This provides a clean abstraction layer for generating different output formats. + end +end diff --git a/lib/grape-swagger/model_builder/operation_builder.rb b/lib/grape-swagger/model_builder/operation_builder.rb new file mode 100644 index 00000000..03cb26a4 --- /dev/null +++ b/lib/grape-swagger/model_builder/operation_builder.rb @@ -0,0 +1,127 @@ +# frozen_string_literal: true + +module GrapeSwagger + module ModelBuilder + # Builds ApiModel::Operation objects from Grape route definitions. + class OperationBuilder + def initialize(schema_builder, definitions = {}) + @schema_builder = schema_builder + @parameter_builder = ParameterBuilder.new(schema_builder) + @response_builder = ResponseBuilder.new(schema_builder, definitions) + @definitions = definitions + end + + # Build an operation from route and parsed parameters/responses + def build(method:, params:, responses:, route_options:, content_types: {}) + operation = ApiModel::Operation.new + + # Basic info + operation.operation_id = route_options[:operation_id] + operation.summary = route_options[:summary] + operation.description = route_options[:description] + operation.deprecated = route_options[:deprecated] if route_options.key?(:deprecated) + operation.tags = Array(route_options[:tags]) if route_options[:tags] + + # Content types (Swagger 2.0 style) + operation.produces = content_types[:produces] if content_types[:produces] + operation.consumes = content_types[:consumes] if content_types[:consumes] + + # Security + operation.security = route_options[:security] if route_options[:security] + + # Build parameters + build_parameters(operation, params, content_types[:consumes]) + + # Build responses + build_responses(operation, responses, content_types[:produces]) + + # Copy extension fields + route_options.each do |key, value| + operation.extensions[key] = value if key.to_s.start_with?('x-') + end + + operation + end + + private + + def build_parameters(operation, params, consumes) + return unless params&.any?

New exporters: - Base - Abstract base class with common utilities - Swagger2 - Produces Swagger 2.0 output (validates refactor) - OAS30 - Produces OpenAPI 3.0 output with: - requestBody instead of body parameters - components/schemas instead of definitions - servers array instead of host/basePath/schemes - Schema wrapper for parameters - Content wrapper for responses - nullable: true for nullable fields - OAS31 - Extends OAS30 with: - type: ["string", "null"] instead of nullable keyword - License identifier support (SPDX) Factory method GrapeSwagger::Exporter.for_version(version) returns the appropriate exporter class. --- lib/grape-swagger/exporter.rb | 52 ++++ lib/grape-swagger/exporter/base.rb | 70 +++++ lib/grape-swagger/exporter/oas30.rb | 397 +++++++++++++++++++++++++

Fix rubocop offenses on added files - Fix duplicate method definition for Parameter#required - Replace case statements with hash lookups to avoid duplicate branches - Fix unused method arguments - Fix line length issues - Move constants outside private section - Apply auto-corrections for style offenses Remaining offenses are Metrics-related (complexity, method length) which require more significant refactoring. --- lib/grape-swagger/api_model/parameter.rb | 23 ++++--- lib/grape-swagger/api_model/request_body.rb | 4 +- lib/grape-swagger/api_model/response.rb | 4 +-

[PATCH 20/45] Refactor complex methods to fix Metrics rubocop offenses Extract helper methods from large to_h and export_* methods to reduce cyclomatic complexity, ABC size, and method length: - api_model/schema.rb: Split to_h into add_*_fields helpers - api_model/operation.rb: Split to_h and to_swagger2_h - api_model/components.rb: Split to_h into add_*_components - api_model/parameter.rb: Split to_swagger2_h - api_model/spec.rb: Split to_swagger2_h - exporter/oas30.rb: Refactor export_schema into build_schema_output - exporter/oas31.rb: Leverage OAS30 helpers, add 3.1-specific methods - exporter/swagger2.rb: Refactor export, export_parameter, export_schema - model_builder/schema_builder.rb: Split build_from_param - model_builder/spec_builder.rb: Split build_operation, build_response - doc_methods.rb: Auto-correct style offenses --- lib/grape-swagger/api_model/components.rb | 28 ++- lib/grape-swagger/api_model/operation.rb | 46 ++--

[PATCH 22/45] Add P2 OAS3 features: additional_properties, discriminator, links, callbacks Additional Properties: - Add OAS3 test for additional_properties with various types - Fix additionalProperties $ref conversion from #/definitions to #/components/schemas Discriminator: - Add discriminator parsing in SchemaBuilder - Add comprehensive tests for discriminator with allOf inheritance - Support both string and object discriminator formats Links and Callbacks: - Add callbacks export in operation - Add links and callbacks in components export - Update components_empty? to check for links/callbacks - Add comprehensive tests for response links and operation callbacks All 727 tests pass. --- lib/grape-swagger/exporter/oas30.rb | 30 ++- .../model_builder/schema_builder.rb

00:00:00 2001 From: Andrey Subbota Date: Thu, 4 Dec 2025 04:04:28 +0100 Subject: [PATCH 23/45] Add nullable handling and port additional OAS3 specs Nullable handling: - Add document_nullable to ParseParams to extract nullable from documentation - Add nullable to MoveParams.property_keys for definition preservation - Add nullable to SchemaBuilder.apply_param_constraints for schema flow - OAS 3.0: outputs nullable: true - OAS 3.1: outputs type: ["string", "null"] New OAS3 specs ported from Swagger 2.0: - param_type_spec.rb: query, path, header params with schema wrapper - extensions_spec.rb: x- extensions at root and operation level - detail_spec.rb: summary and description handling - status_codes_spec.rb: HTTP status code handling - nullable_handling_spec.rb: nullable

Update this documentation From 9eef83a21aeb0faa2cd847ae7af317c3d8ef096d Mon Sep 17 00:00:00 2001 From: Andrey Subbota Date: Thu, 4 Dec 2025 12:51:00 +0100 Subject: [PATCH 25/45] Enable DirectSpecBuilder for OAS3 generation with nested entity support Switch OAS3 generation from conversion-based approach to direct building from Grape routes. This preserves all route options and fixes nested entity handling. Key changes: - Route OAS3 requests through DirectSpecBuilder instead of converting from Swagger 2.0 output - Pass DirectSpecBuilder instance to model parsers so nested entities can call expose_params_from_model for proper registration - Add schema_ref_with_description using allOf pattern for refs with descriptions - Handle canonical_name in additionalProperties export All 771 tests pass (293 OAS3 + 220 Swagger 2.0 + issue specs). --- lib/grape-swagger/doc_methods.rb | 33 +- lib/grape-swagger/exporter/oas30.rb | 21 +- lib/grape-swagger/model_builder.rb | 1 + .../model_builder/direct_spec_builder.rb | 1038 +++++++++++++++++ 4 files changed, 1087 insertions(+), 6 deletions(-) create mode 100644 lib/grape-swagger/model_builder/direct_spec_builder.rb diff --git a/lib/grape-swagger/doc_methods.rb b/lib/grape-swagger/doc_methods.rb index 838abd2d..64cc6aa9 100644 --- a/lib/grape-swagger/doc_methods.rb +++ b/lib/grape-swagger/doc_methods.rb @@ -48,7 +48,16 @@ module DocMethods FORMATTER_METHOD = %i[format default_format default_error_formatter].freeze def self.output_path_definitions(combi_routes, endpoint, target_class, options) - # Generate Swagger 2.0 output (always, as base) + if options[:openapi_version] + # Build OpenAPI 3.x directly from Grape routes (no information loss) + build_openapi3_directly(combi_routes, endpoint, target_class, options) + else + # Generate Swagger 2.0 output (original flow) + build_swagger2_output(combi_routes, endpoint, target_class, options) + end + end + + def self.build_swagger2_output(combi_routes, endpoint, target_class, options) output = endpoint.swagger_object( target_class, endpoint.request, @@ -62,12 +71,28 @@ def self.output_path_definitions(combi_routes, endpoint, target_class, options) output[:paths] = paths unless paths.blank?

-### Data Flow - -**When `openapi_version: '3.0'` or `'3.1'` is set:** -1. **FromRoutes** builder creates OpenAPI::Document directly from Grape routes -2. **Exporter** (OAS30/OAS31) converts OpenAPI::Document → OpenAPI output - -**When no `openapi_version` is set (default):** -1. **Grape Endpoint** generates Swagger 2.0 hash (existing behavior unchanged) - ---- - -## Quick Start - -### Basic Usage - -```ruby -class MyAPI < Grape::API - format :json - - desc 'Get all users' - get '/users' do - User.all - end - - # Enable OpenAPI 3.0 - add_swagger_documentation(openapi_version: '3.0') -end -``` - -### Output Comparison - -**Swagger 2.0:** -```json -{ - "swagger": "2.0", - "info": { "title": "API", "version": "1.0" }, - "host": "api.example.com", - "basePath": "/v1", - "paths": { ... }, - "definitions": { ... } -} -``` - -**OpenAPI 3.0:** -```json -{ - "openapi": "3.0.3", - "info": { "title": "API", "version": "1.0" }, - "servers": [{ "url": "https://api.example.com/v1" }], - "paths": { ... }, - "components": { "schemas": { ... } } -} -``` - ---- - -## Key Differences from Swagger 2.0 - -| Aspect | Swagger 2.0 | OpenAPI 3.x | -|--------|-------------|-------------| -| Version | `swagger: '2.0'` | `openapi: '3.0.3'` / `'3.1.0'` | -| Body params | `in: body` parameter | `requestBody` object | -| Form params | `in: formData` | `requestBody` with `multipart/form-data` | -| File upload | `type: file` | `type: string, format: binary` | -| Content types | global `produces`/`consumes` | per-operation `content` | -| Schema refs | `#/definitions/X` | `#/components/schemas/X` | -| Host | `host`, `basePath`, `schemes` | `servers: [{url: "..."}]` | -| Security defs | `securityDefinitions` | `components/securitySchemes` | -| Param types | inline `type`, `format` | wrapped in `schema` | -| Nullable (3.0) | N/A | `nullable: true` | -| Nullable (3.1) | N/A | `type: ["string", "null"]` | - ---- - -## Implementation Details - -### Request Body Transformation - -Swagger 2.0 body parameters are automatically converted to OAS3 requestBody: - -```ruby -# Grape params -params do - requires :name, type: String - requires :email, type: String -end -post '/users' do - # ... -end -``` - -**Swagger 2.0 output:** -```json -{ - "parameters": [{ - "in": "body", - "name": "postUsers", - "schema": { "$ref": "#/definitions/postUsers" } - }] -} -``` - -**OpenAPI 3.0 output:** -```json -{ - "requestBody": { - "required": true, - "content": { - "application/json": { - "schema": { "$ref": "#/components/schemas/postUsers" } - } - } - } -} -``` - -### Parameter Schema Wrapping - -OAS3 requires parameters to have a `schema` wrapper: - -**Swagger 2.0:** -```json -{ "name": "id", "in": "path", "type": "integer", "format": "int32" } -``` - -**OpenAPI 3.0:** -```json -{ "name": "id", "in": "path", "schema": { "type": "integer", "format": "int32" } } -``` - -### Nullable Handling - -```ruby -params do - optional :nickname, type: String, documentation: { nullable: true } -end -``` - -**OAS 3.0:** `{ "type": "string", "nullable": true }` - -**OAS 3.1:** `{ "type": ["string", "null"] }` -

---- - -## OpenAPI Model Layer - -The OpenAPI Model layer provides version-agnostic data structures: - -### OpenAPI::Document - -Root container for the entire specification: - -```ruby -spec = GrapeSwagger::OpenAPI::Document.new -spec.info.title = "My API" -spec.info.version = "1.0" -spec.add_server(GrapeSwagger::OpenAPI::Server.new(url: "https://api.example.com")) -spec.add_path("/users", path_item) -spec.components.add_schema("User", user_schema) -``` - -### OpenAPI::Schema - -Represents JSON Schema, used for request/response bodies and parameters: - -```ruby -schema = GrapeSwagger::OpenAPI::Schema.new( - type: 'object', - nullable: true, - description: 'A user object' -) -schema.add_property('name', GrapeSwagger::OpenAPI::Schema.new(type: 'string')) -schema.add_property('email', GrapeSwagger::OpenAPI::Schema.new(type: 'string')) -schema.mark_required('name') -schema.mark_required('email') -``` - -### OpenAPI::Operation - -Represents an HTTP operation: - -```ruby -operation = GrapeSwagger::OpenAPI::Operation.new -operation.operation_id = "getUsers" -operation.summary = "List all users" -operation.tags = ["Users"] -operation.add_parameter(param) -operation.request_body = request_body -operation.add_response(200, success_response) -``` - ---- - -## Exporters - -### Base Exporter - -Provides common functionality for all exporters: - -```ruby -class GrapeSwagger::Exporter::Base - def initialize(spec) - @spec = spec # OpenAPI::Document instance - end - - def export - raise NotImplementedError - end -end -``` - -### OAS30 Exporter - -Converts OpenAPI::Document to OpenAPI 3.0 format: - -- Outputs `openapi: '3.0.3'` -- Converts `#/definitions/` → `#/components/schemas/` -- Wraps parameters in `schema` -- Converts body params → `requestBody` -- Uses `nullable: true` for nullable types - -### OAS31 Exporter - -Extends OAS30 with 3.1-specific features: - -- Outputs `openapi: '3.1.0'` -- Uses `type: ["string", "null"]` instead of `nullable: true` -- Supports `license.identifier` (SPDX) -- Supports `webhooks` -- Supports `jsonSchemaDialect` - ---- - -## Builders - -### FromRoutes (Primary for OAS 3.x) - -Builds OpenAPI::Document directly from Grape routes without going through Swagger 2.0 format. This is the recommended approach for OAS 3.x as it preserves all route options and properly handles nested entities. - -```ruby -builder = GrapeSwagger::OpenAPI::Builder::FromRoutes.new( - endpoint, target_class, request, options -) -spec = builder.build(namespace_routes) -``` - -Key features: -- Direct route introspection (no information loss) -- Proper nested entity handling via model parsers -- Full support for requestBody, components, servers -- Handles Array[Entity] types and inline schemas -- Recursive exposure of $ref nested entities - -### FromHash (Conversion-based) - -Converts existing Swagger 2.0 hash to OpenAPI::Document. Used when converting legacy specs: - -```ruby -builder = GrapeSwagger::OpenAPI::Builder::FromHash.new(options) -spec = builder.build_from_swagger_hash(swagger_hash) -``` - -Handles: -- Info object construction -- Server building from host/basePath/schemes -- Path and operation building -- Definition → components/schemas conversion -- Security scheme conversion - -### SchemaBuilder - -Builds Schema objects from various inputs: - -```ruby -builder = GrapeSwagger::OpenAPI::Builder::SchemaBuilder.new(definitions) - -# From type -schema = builder.build(String, nullable: true) - -# From param hash -schema = builder.build_from_param({ type: 'string', nullable: true }) - -# From definition hash -schema = builder.build_from_definition({ type: 'object', properties: {...} }) -``` - ---- - -## OAS 3.0 vs 3.1 Differences - -### Nullable Handling - -**OAS 3.0:** -```ruby -def nullable_keyword? - true # Use nullable: true -end -``` - -**OAS 3.1:** -```ruby -def nullable_keyword? - false # Use type array: ["string", "null"] -end -``` - -### License Identifier - -OAS 3.1 supports SPDX license identifiers: - -```ruby -add_swagger_documentation( - openapi_version: '3.1', - info: { - license: { - name: 'MIT', - identifier: 'MIT' # SPDX identifier (3.1 only) - } - } -) -``` - -### Webhooks (OAS 3.1) - -```ruby -spec.add_webhook('newUser', webhook_path_item) -``` - -Output: -```json -{ - "webhooks": { - "newUser": { - "post": { ... } - } - } -} -``` - -### JSON Schema Dialect (OAS 3.1) - -```ruby -spec.json_schema_dialect = 'https://json-schema.org/draft/2020-12/schema' -``` - ---- - -## Test Coverage - -### Test Files - -``` -spec/openapi_v3/ -├── openapi_version_spec.rb # Version configuration -├── integration_spec.rb # Full API integration tests -├── type_format_spec.rb # Type/format mappings -├── form_data_spec.rb # Form data handling -├── file_upload_spec.rb # File upload handling -├── params_array_spec.rb # Array parameter handling -├── param_type_spec.rb # Query/path/header params -├── param_type_body_nested_spec.rb # Nested body params -├── response_models_spec.rb # Response model handling -├── composition_schemas_spec.rb # allOf/oneOf/anyOf -├── additional_properties_spec.rb # additionalProperties -├── discriminator_spec.rb # Discriminator support -├── links_callbacks_spec.rb # Links and callbacks -├── extensions_spec.rb # x- extensions -├── detail_spec.rb # Summary/description -├── status_codes_spec.rb # HTTP status codes -├── null_type_spec.rb # Null type handling -├── nullable_fields_spec.rb # Nullable fields -├── nullable_handling_spec.rb # Nullable integration -└── oas31_features_spec.rb # OAS 3.1 specific features -``` - -### Test Counts - -- **Total tests**: 771 -- **OAS3 tests**: 293 -- **All passing**: Yes - -### Running Tests - -```bash -# All tests -bundle exec rspec - -# OAS3 tests only -bundle exec rspec spec/openapi_v3/ - -# Specific feature -bundle exec rspec spec/openapi_v3/nullable_handling_spec.rb -``` - ---- - -## Backward Compatibility - -The implementation maintains 100% backward compatibility: - -1. **Default behavior unchanged** - Without `openapi_version`, Swagger 2.0 is generated -2. **All existing tests pass** - No changes to Swagger 2.0 output -3. **Same configuration options** - All existing options work with OAS3 -4. **Model parsers unchanged** - grape-entity, representable, etc. work as before - ---- - -## Future Enhancements - -Potential areas for future development: - -1. **Dry-types/Dry-validation support** - New model parser gem (e.g., `grape-swagger-dry`) -2. **Reusable components** - responses, parameters, requestBodies in components -3. **XML support** - Schema XML properties -4. **Complex parameter serialization** - `content` instead of `schema` -5. **OpenAPI 3.2** - When specification is finalized - ---- - -## Contributing - -When adding new OAS3 features: - -1.
