227+---
228+
229+* Major changes:

279+
280+* Minor changes:
281+ * Use Swagger formats for `Int32`, `Int64`, `Float`, `Double`, `Day` and `ZonedTime` (see [#32](https://github.com/GetShopTV/swagger2/pull/32));

295+ * Introduce `SwaggerItems` GADT, replacing `Items` and `SchemaItems` in `ParamSchema` (see [#24](https://github.com/GetShopTV/swagger2/pull/24));
296+ * Move type, format and items fields to `ParamSchema` (former `SchemaComon`);
297+ * Prepend reference path automatically (see [commit 49d1fad](https://github.com/GetShopTV/swagger2/commit/49d1fadd2100644e70c442667180d0d73e107a5f))
298+ and thus remove `"#/definitions/"` from user code, leaving much clearer `Reference "Name"`;
299+ * Change `Data.Swagger.Schema` (see [#19](https://github.com/GetShopTV/swagger2/pull/19)):
300+ * Change the only method of `ToSchema` to `declareNamedSchema` which should produce a `NamedSchema`
301+ along with a list of schema definitions used to produce it;
302+ * Add `declareSchema`, `declareSchemaRef`;
303+ * Replace `genericTo*` helpers with `genericDeclare*` helpers;
304+ * Add `paramSchemaTo[Named]Schema` helpers to facilitate code reuse for primitive schemas;
305+ * Add helpers for inlining `Schema` references dynamically (see [#23](https://github.com/GetShopTV/swagger2/pull/23));
306+ * Add `ToParamSchema` class (see [#17](https://github.com/GetShopTV/swagger2/pull/17)) with
307+ * generic default implementation and
308+ * instances for some base types compliant with `http-api-data` instances;
309+ * Add `Data.Swagger.Declare` module with
310+ * `DeclareT` monad transformer;
311+ * `MonadDeclare` type class;
312+ * various helpers;

314+ * `Parameter` -> `Param`;
315+ * `ParameterSchema` -> `ParamAnySchema`;
316+ * `ParameterOtherSchema` -> `ParamOtherSchema`;
317+ * `ParameterLocation` -> `ParamLocation`;
318+ * `SchemaCommon` -> `ParamSchema`;
319+ * `parameter*` fields renamed to `param*` fields;
320+ * `schemaCommon*` fields renamed to `paramSchema*` fields;
321+ * `HasSchemaCommon` -> `HasParamSchema`.
322+
323+* Minor changes:
324+ * Replace TH-generated JSON instances with `Generic`-based (see [#25](https://github.com/GetShopTV/swagger2/pull/25));
325+ * Drop `template-haskell` dependency;
326+ * Omit empty array/object properties from `toJSON` output ([#22](https://github.com/GetShopTV/swagger2/pull/22));
327+ * Remove `minLength` property from schemas for `time` types;
328+ * Move `SchemaOptions` to `Data.Swagger.SchemaOptions`;
329+ * Remove `useReferences` from `SchemaOptions` (see [#23](https://github.com/GetShopTV/swagger2/pull/23));
330+ * Place all internal submodules under `Data.Swagger.Internal`;
331+ * Better documentation (see [#26](https://github.com/GetShopTV/swagger2/pull/26)).
332+
333+0.4.1
334+---
335+* Fixes:
336+ * Use `PackageImports` for `Data.HashSet` to avoid test failure on stackage (see [#15](https://github.com/GetShopTV/swagger2/issues/15));
337+ * Add an upper version bound for `aeson` due to `aeson-0.10.0.0` bug (see [bos/aeson#293](https://github.com/bos/aeson/issues/293));
338+ * Switch to Cabal-based multi GHC Travis config.
339+
340+0.4
341+---
342+* Remove `Swagger`/`swagger` prefixes;
343+* Add `ToSchema` type class with default generic implementation;
344+* Add configurable generic `ToSchema` helpers;
345+* Add `doctest` test suite;
346+* Fixes:
347+ * Fix `HasSchemaCommon` instance for `Schema`;

349+ not necessarily an integer;
350+ * Fix all warnings.
351+
352+0.3
353+---
354+* Fixes:
355+ * Fix `SwaggerMonoid Text` instance;
356+ * Wrap `Bool` in `Maybe` everywhere;
357+ * These changes make all `Data.Swagger` `Monoid` instances obey monoid laws
358+ (previously right identity law was broken by some instances).
359+
360+0.2
361+---
362+* Add `Data.Swagger.Lens`;
363+* Support references;
364+* Fixes:
365+ * Fix `FromJSON SwaggerHost` instance;

8+OpenAPI 3.0 data model.
9+
10+The original OpenAPI 3.0 specification is available at http://swagger.io/specification/.
11+
12+This package is heavily based on excellent work on Swagger 2.0 at
13+https://github.com/GetShopTV/swagger2.
14+
15+## Usage
16+
17+This library is intended to be used for decoding and encoding OpenApi 3.0.3 specifications as well as manipulating them.
18+
19+Please refer to [haddock documentation](http://hackage.haskell.org/package/openapi3).
20+
21+Some examples can be found in [`examples/` directory](/examples).
22+
23+## Trying out
24+
25+All generated swagger specifications can be interactively viewed on [Swagger Editor](http://editor.swagger.io/).
26+
27+Ready-to-use specification can be served as JSON and interactive API documentation
28+can be displayed using [Swagger UI](https://github.com/swagger-api/swagger-ui).
29+
30+Many Swagger tools, including server and client code generation for many languages, can be found on
31+[Swagger's Tools and Integrations page](http://swagger.io/open-source-integrations/).
32+
33+## Contributing
34+
35+We are happy to receive bug reports, fixes, documentation enhancements, and other improvements.
36+
37+Please report bugs via the [github issue tracker](https://github.com/biocad/openapi3/issues).

6+-- Swagger™ is a project used to describe and document RESTful APIs.
7+--
8+-- The Swagger specification defines a set of files required to describe such an API.
9+-- These files can then be used by the Swagger-UI project to display the API
10+-- and Swagger-Codegen to generate clients in various languages.
11+-- Additional utilities can also take advantage of the resulting files, such as testing tools.

146+-- $howto
147+--
148+-- This section explains how to use this library to work with Swagger specification.
149+
150+-- $monoids
151+--
152+-- Virtually all types representing Swagger specification have @'Monoid'@ instances.
153+-- The @'Monoid'@ type class provides two methods — @'mempty'@ and @'mappend'@.
154+--
155+-- In this library you can use @'mempty'@ for a default/empty value. For instance:
156+--
157+-- >>> BSL.putStrLn $ encodePretty (mempty :: OpenApi)
158+-- {
159+-- "components": {},
160+-- "info": {
161+-- "title": "",
162+-- "version": ""
163+-- },
164+-- "openapi": "3.0.0",
165+-- "paths": {}
166+-- }
167+--
168+-- As you can see some spec properties (e.g. @"version"@) are there even when the spec is empty.
169+-- That is because these properties are actually required ones.
170+--
171+-- You /should/ always override the default (empty) value for these properties,
172+-- although it is not strictly necessary:
173+--
174+-- >>> BSL.putStrLn $ encodePretty mempty { _infoTitle = "Todo API", _infoVersion = "1.0" }
175+-- {
176+-- "title": "Todo API",
177+-- "version": "1.0"
178+-- }
179+--
180+-- You can merge two values using @'mappend'@ or its infix version @('<>')@:
181+--
182+-- >>> BSL.putStrLn $ encodePretty $ mempty { _infoTitle = "Todo API" } <> mempty { _infoVersion = "1.0" }
183+-- {
184+-- "title": "Todo API",
185+-- "version": "1.0"
186+-- }
187+
188+--
189+-- This can be useful for combining specifications of endpoints into a whole API specification:
190+--
191+-- @
192+-- \-\- /account subAPI specification
193+-- accountAPI :: OpenApi
194+--
195+-- \-\- /task subAPI specification
196+-- taskAPI :: OpenApi
197+--
198+-- \-\- while API specification is just a combination
199+-- \-\- of subAPIs' specifications
200+-- api :: OpenApi
201+-- api = accountAPI <> taskAPI
202+-- @
203+
204+-- $lens
205+--
206+-- Note: if you're working with the <https://hackage.haskell.org/package/optics optics> library, take a look at "Data.OpenApi.Optics".
207+--
208+-- Since @'Swagger'@ has a fairly complex structure, lenses and prisms are used
209+-- to work comfortably with it. In combination with @'Monoid'@ instances, lenses
210+-- make it fairly simple to construct/modify any part of the specification:
211+--
212+-- >>> :{
213+-- BSL.putStrLn $ encodePretty $ (mempty :: OpenApi)
214+-- & components . schemas .~ [ ("User", mempty & type_ ?~ OpenApiString) ]
215+-- & paths .~
216+-- [ ("/user", mempty & get ?~ (mempty
217+-- & at 200 ?~ ("OK" & _Inline.content.at "application/json" ?~ (mempty & schema ?~ Ref (Reference "User")))
218+-- & at 404 ?~ "User info not found")) ]
219+-- :}
220+-- {
221+-- "components": {
222+-- "schemas": {
223+-- "User": {
224+-- "type": "string"
225+-- }
226+-- }
227+-- },
228+-- "info": {
229+-- "title": "",
230+-- "version": ""
231+-- },
232+-- "openapi": "3.0.0",
233+-- "paths": {
234+-- "/user": {
235+-- "get": {
236+-- "responses": {
237+-- "200": {
238+-- "content": {
239+-- "application/json": {
240+-- "schema": {
241+-- "$ref": "#/components/schemas/User"
242+-- }
243+-- }
244+-- },
245+-- "description": "OK"
246+-- },
247+-- "404": {
248+-- "description": "User info not found"
249+-- }
250+-- }
251+-- }
252+-- }
253+-- }
254+-- }
255+--
256+-- In the snippet above we declare an API with a single path @/user@. This path provides method @GET@
257+-- which produces @application/json@ output. It should respond with code @200@ and body specified
258+-- by schema @User@ which is defined in @'definitions'@ property of swagger specification.
259+-- Alternatively it may respond with code @404@ meaning that user info is not found.
260+--
261+-- For convenience, @swagger2@ uses /classy field lenses/. It means that
262+-- field accessor names can be overloaded for different types. One such
263+-- common field is @'description'@. Many components of a Swagger specification
264+-- can have descriptions, and you can use the same name for them:
265+--
266+-- >>> BSL.putStrLn $ encodePretty $ (mempty :: Response) & description .~ "No content"
267+-- {
268+-- "description": "No content"
269+-- }
270+-- >>> :{
271+-- BSL.putStrLn $ encodePretty $ (mempty :: Schema)
272+-- & type_ ?~ OpenApiBoolean
273+-- & description ?~ "To be or not to be"
274+-- :}
275+-- {
276+-- "description": "To be or not to be",
277+-- "type": "boolean"
278+-- }
279+--
280+-- Additionally, to simplify working with @'Response'@, both @'Operation'@ and @'Responses'@
281+-- have direct access to it via @'at' code@. Example:
282+--
283+-- >>> :{
284+-- BSL.putStrLn $ encodePretty $ (mempty :: Operation)
285+-- & at 404 ?~ "Not found"
286+-- :}
287+-- {
288+-- "responses": {
289+-- "404": {
290+-- "description": "Not found"
291+-- }
292+-- }
293+-- }
294+--
295+-- You might've noticed that @'type_'@ has an extra underscore in its name
296+-- compared to, say, @'description'@ field accessor.
297+-- This is because @type@ is a keyword in Haskell.
298+-- A few other field accessors are modified in this way:
299+--
300+-- - @'in_'@, @'type_'@, @'default_'@ (as keywords);
301+-- - @'maximum_'@, @'minimum_'@, @'head_'@ (as conflicting with @Prelude@);
302+-- - @'enum_'@ (as conflicting with @Control.Lens@).
303+
304+-- $schema
305+--
306+-- @'ParamSchema'@ and @'Schema'@ are the two core types for data model specification.
307+--
308+-- @'ParamSchema' t@ specifies all the common properties, available for every data schema.
309+-- The @t@ parameter imposes some restrictions on @type@ and @items@ properties (see @'OpenApiType'@ and @'OpenApiItems'@).
310+--
311+-- @'Schema'@ is used for request and response bodies and allows specifying objects
312+-- with properties in addition to what @'ParamSchema'@ provides.
313+--
314+-- In most cases you will have a Haskell data type for which you would like to
315+-- define a corresponding schema. To facilitate this use case
316+-- @swagger2@ provides two classes for schema encoding.
317+-- Both these classes provide means to encode /types/ as Swagger /schemas/.
318+--
319+-- @'ToParamSchema'@ is intended to be used for primitive API endpoint parameters,
320+-- such as query parameters, headers and URL path pieces.
321+-- Its corresponding value-encoding class is @'ToHttpApiData'@ (from @http-api-data@ package).
322+--
323+-- @'ToSchema'@ is used for request and response bodies and mostly differ from
324+-- primitive parameters by allowing objects/mappings in addition to primitive types and arrays.
325+-- Its corresponding value-encoding class is @'ToJSON'@ (from @aeson@ package).
326+--
327+-- While lenses and prisms make it easy to define schemas, it might be that you don't need to:
328+-- @'ToSchema'@ and @'ToParamSchema'@ classes both have default @'Generic'@-based implementations!
329+--
330+-- @'ToSchema'@ default implementation is also aligned with @'ToJSON'@ default implementation with
331+-- the only difference being for sum encoding. @'ToJSON'@ defaults sum encoding to @'defaultTaggedObject'@,
332+-- while @'ToSchema'@ defaults to something which corresponds to @'ObjectWithSingleField'@. This is due to
333+-- @'defaultTaggedObject'@ behavior being hard to specify in Swagger.
334+--
335+-- Here's an example showing @'ToJSON'@–@'ToSchema'@ correspondance:
336+--
337+-- >>> data Person = Person { name :: String, age :: Integer } deriving Generic
338+-- >>> instance ToJSON Person
339+-- >>> instance ToSchema Person
340+-- >>> BSL.putStrLn $ encodePretty (Person "David" 28)
341+-- {
342+-- "age": 28,
343+-- "name": "David"
344+-- }
345+-- >>> BSL.putStrLn $ encodePretty $ toSchema (Proxy :: Proxy Person)
346+-- {
347+-- "properties": {
348+-- "age": {
349+-- "type": "integer"
350+-- },
351+-- "name": {
352+-- "type": "string"
353+-- }
354+-- },
355+-- "required": [
356+-- "name",
357+-- "age"
358+-- ],
359+-- "type": "object"
360+-- }
361+--
362+-- This package implements OpenAPI 3.0 spec, which supports @oneOf@ in schemas, allowing any sum types
363+-- to be faithfully represented. All sum encodings supported by @aeson@ are supported here as well, with
364+-- an exception of 'Data.Aeson.TwoElemArray', since OpenAPI spec does not support heterogeneous arrays.
365+--
366+-- An example with 'Data.Aeson.TaggedObject' encoding:
367+--
368+-- >>> data Error = ErrorNoUser { userId :: Int } | ErrorAccessDenied { requiredPermission :: String } deriving Generic
369+-- >>> instance ToJSON Error
370+-- >>> instance ToSchema Error
371+-- >>> BSL.putStrLn $ encodePretty $ toSchema (Proxy :: Proxy Error)
372+-- {
373+-- "oneOf": [
374+-- {
375+-- "properties": {
376+-- "tag": {
377+-- "enum": [
378+-- "ErrorNoUser"
379+-- ],
380+-- "type": "string"
381+-- },
382+-- "userId": {
383+-- "maximum": 9223372036854775807,
384+-- "minimum": -9223372036854775808,
385+-- "type": "integer"
386+-- }
387+-- },
388+-- "required": [
389+-- "userId",
390+-- "tag"
391+-- ],
392+-- "type": "object"
393+-- },
394+-- {
395+-- "properties": {
396+-- "requiredPermission": {
397+-- "type": "string"
398+-- },
399+-- "tag": {
400+-- "enum": [
401+-- "ErrorAccessDenied"
402+-- ],
403+-- "type": "string"
404+-- }
405+-- },
406+-- "required": [
407+-- "requiredPermission",
408+-- "tag"
409+-- ],
410+-- "type": "object"
411+-- }
412+-- ],
413+-- "type": "object"
414+-- }
415+
416+-- $manipulation
417+-- Sometimes you have to work with an imported or generated @'Swagger'@.
418+-- For instance, <servant-swagger http://hackage.haskell.org/package/servant-swagger> generates basic @'Swagger'@
419+-- for a type-level servant API.
420+--
421+-- Lenses and prisms can be used to manipulate such specification to add additional information, tags, extra responses, etc.
422+-- To facilitate common needs, @"Data.OpenApi.Operation"@ module provides useful helpers.
423+
424+-- $validation
425+-- While @'ToParamSchema'@ and @'ToSchema'@ provide means to easily obtain schemas for Haskell types,
426+-- there is no static mechanism to ensure those instances correspond to the @'ToHttpApiData'@ or @'ToJSON'@ instances.
427+--
428+-- @"Data.OpenApi.Schema.Validation"@ addresses @'ToJSON'@/@'ToSchema'@ validation.

82+-- {

87+-- Additionally, to simplify working with @'Response'@, both @'Operation'@ and
88+-- @'Responses'@ have direct access to it via @'Optics.Core.At.at'@. Example:

42+-- $howto
43+--
44+-- This module provides helpful functions for JSON validation.
45+-- These functions are meant to be used in test suites for your application
46+-- to ensure that JSON respresentation for your data corresponds to
47+-- schemas you're using for the Swagger specification.
48+--
49+-- It is recommended to use validation functions as QuickCheck properties
50+-- (see <http://hackage.haskell.org/package/QuickCheck>).
51+
52+-- $examples
53+--
54+-- >>> validateToJSON "hello"
55+-- []
56+--
57+-- >>> validateToJSON False
58+-- []
59+--
60+-- >>> newtype Nat = Nat Integer deriving Generic
61+-- >>> instance ToJSON Nat where toJSON (Nat n) = toJSON n
62+-- >>> instance ToSchema Nat where declareNamedSchema proxy = genericDeclareNamedSchema defaultSchemaOptions proxy & mapped.minimum_ ?~ 0
63+-- >>> validateToJSON (Nat 10)
64+-- []
65+-- >>> validateToJSON (Nat (-5))
66+-- ["value -5.0 falls below minimum (should be >=0.0)"]
67+
68+-- $maybe
69+--
70+-- Because @'Maybe' a@ has the same schema as @a@, validation
71+-- generally fails for @null@ JSON:
72+--
73+-- >>> validateToJSON (Nothing :: Maybe String)
74+-- ["expected JSON value of type OpenApiString"]
75+-- >>> validateToJSON ([Just "hello", Nothing] :: [Maybe String])
76+-- ["expected JSON value of type OpenApiString"]
77+-- >>> validateToJSON (123, Nothing :: Maybe String)
78+-- ["expected JSON value of type OpenApiString"]
79+--
80+-- However, when @'Maybe' a@ is a type of a record field,
81+-- validation takes @'required'@ property of the @'Schema'@
82+-- into account:
83+--
84+-- >>> data Person = Person { name :: String, age :: Maybe Int } deriving Generic
85+-- >>> instance ToJSON Person
86+-- >>> instance ToSchema Person
87+-- >>> validateToJSON (Person "Nick" (Just 24))
88+-- []
89+-- >>> validateToJSON (Person "Nick" Nothing)
