## Usage

### Start using it

1. Add comments to your API source code, [See Declarative Comments Format](https://swaggo.github.io/swaggo.io/declarative_comments_format/).
2. Download [Swag](https://github.com/swaggo/swag) for Go by using:

```sh
$ go install github.com/swaggo/swag/cmd/swag@latest

# if you find swag cli not work, you can try to install swag cli from source
git clone git@github.com:swaggo/swag.git
cd swag
# tag variable should match with github.com/swaggo/swag in go.mod
# here we use v1.8.10
git checkout -b ${tag} tags/${tag}
go install ./cmd/swag
```

3. Run the [Swag](https://github.com/swaggo/swag) in your Go project root folder which contains `main.go` file, [Swag](https://github.com/swaggo/swag) will parse comments and generate required files(`docs` folder and `docs/doc.go`).

```sh
$ swag init
```

4. Download [swagger for Iris](https://github.com/iris-contrib/swagger) by using:

```sh
$ go get github.com/iris-contrib/swagger/v12@master
```

And import following in your code:

```go
import "github.com/iris-contrib/swagger" // swagger middleware for Iris
import "github.com/iris-contrib/swagger/swaggerFiles" // swagger embed files

```

### Example Code:

```go
package main

import (
"github.com/kataras/iris/v12"

"github.com/iris-contrib/swagger"
"github.com/iris-contrib/swagger/swaggerFiles"

_ "github.com/your_username/your_project/docs"
// docs folder should be generated by Swag CLI (swag init),
// you have to import it.
)

// @title Swagger Example API
// @version 1.0
// @description This is a sample server Petstore server.
// @termsOfService http://swagger.io/terms/

// @contact.name API Support
// @contact.url http://www.swagger.io/support
// @contact.email support@swagger.io

// @license.name Apache 2.0
// @license.url http://www.apache.org/licenses/LICENSE-2.0.html

// @host localhost:8080
// @BasePath /v2
func main() {
app := iris.New()

swaggerUI := swagger.Handler(swaggerFiles.Handler,
swagger.URL("/swagger/doc.json"),
swagger.DeepLinking(true),
swagger.Prefix("/swagger"),
)

// Register on http://localhost:8080/swagger
app.Get("/swagger", swaggerUI)
// And the wildcard one for index.html, *.js, *.css and e.t.c.
app.Get("/swagger/{any:path}", swaggerUI)

app.Listen(":8080")
}
```

5. Run it, and navigate through , you should see the Swagger 2.0 API documentation page.

6. If you want to disable swagger when some environment variable is set, use `DisablingHandler` instead of `Handler`.

```go
swagger.DisablingHandler(swaggerFiles.Handler, "THE_OS_VARIABLE_NAME_HERE", configurators ...Configurator)
```

7. If you want to change swagger-ui theme, you can add `swagger.SetTheme(swagger.Monokai)` when init `swaggerUI`
```go
swaggerUI := swagger.Handler(swaggerFiles.Handler,
swagger.URL("/swagger/doc.json"),
swagger.DeepLinking(true),
swagger.Prefix("/swagger"),
// ref: https://github.com/ostranme/swagger-ui-themes
// current we support 7 themes
// theme is a optional config, if you not set, it will use default theme
swagger.SetTheme(swagger.Monokai),
)
```
