## Upgrading Grape-swagger

### Upgrading to >= 0.25.2

Avoids ambiguous documentation of array parameters,
by enforcing correct usage of both possibilities:

1. Array of primitive types
  ```ruby
  params do
    requires :foo, type: Array[String]
  end
  ```

2. Array of objects
  ```ruby
  params do
    requires :put_params, type: Array do
      requires :op, type: String
      requires :path, type: String
      requires :value, type: String
    end
  end
```

### Upgrading to >= 0.25.0

The global tag set now only includes tags for documented routes. This behaviour has impact in particular for calling the documtation of a specific route.

### Upgrading to >= 0.21.0

With grape >= 0.21.0, `grape-entity` support moved to separate gem `grape-swagger-entity`, if you use grape entity, update your Gemfile:

```ruby
gem 'grape-swagger'
gem 'grape-swagger-entity'
```

`add_swagger_documentation` has changed from
``` ruby
  add_swagger_documentation \
    api_version: '0.0.1'
```
to

``` ruby
  add_swagger_documentation \
    doc_version: '0.0.1'
```

The API version self, would be set by grape, see -> [spec for #403](https://github.com/ruby-grape/grape-swagger/blob/master/spec/issues/403_versions_spec.rb).



### Upgrading to >= 0.10.2

With grape >= 0.12.0, support for `notes` is replaced by passing a block `detail` option specified. For future compatibility, update your code:

```ruby
desc 'Get all kittens!', notes: 'this will expose all the kittens'
```

to

``` ruby
 desc 'Get all kittens!' do
  detail 'this will expose all the kittens'
end
```
Be aware of https://github.com/ruby-grape/grape/issues/920, currently grape accepts either an option hash OR a block for `desc`.

### Upgrading to >= 0.9.0

#### Grape-Swagger-Rails

If you're using [grape-swagger-rails](https://github.com/ruby-grape/grape-swagger-rails), remove the `.json` extension from `GrapeSwaggerRails.options.url`.

For example, change

```ruby
GrapeSwaggerRails.options.url = '/api/v1/swagger_doc.json'
```

to

```ruby
GrapeSwaggerRails.options.url = '/api/v1/swagger_doc'
```

See [#187](https://github.com/ruby-grape/grape-swagger/issues/187) for more information.

#### Grape 0.10.0

If your API uses Grape 0.10.0 or newer with a single `format :json` directive, add `hide_format: true` to `add_swagger_documentation`. Otherwise nested routes will render with `.json` links to your API documentation, which will fail with a 404 Not Found.

### Upgrading to >= 0.8.0

#### Changes in Configuration

The following options have been added, removed or have been changed in the grape-swagger interface:

* `markdown: true/false` => `markdown: GrapeSwagger::Markdown::KramdownAdapter`

#### Markdown

You can now configure a markdown adapter. This was originally changed because of performance issues with Kramdown and the `markdown` option no longer takes a boolean argument. Built-in adapters include Kramdown and Redcarpet.

##### Kramdown

To configure the markdown with Kramdown, add the kramdown gem to your Gemfile:

`gem 'kramdown'`

Configure grape-swagger as follows:

```ruby
add_swagger_documentation (
    markdown: GrapeSwagger::Markdown::KramdownAdapter
)
```

#### Redcarpet

To configure markdown with Redcarpet, add the redcarpet and the rouge gem to your Gemfile. Note that Redcarpet does not work with JRuby.

```ruby
gem 'redcarpet'
gem 'rouge'
```

Configure grape-swagger as follows:

```ruby
add_swagger_documentation (
    markdown: GrapeSwagger::Markdown::RedcarpetAdapter
)
```

See [#142](https://github.com/ruby-grape/grape-swagger/pull/142) and documentation section [Markdown in Notes](https://github.com/ruby-grape/grape-swagger#markdown-in-notes) for more information.
