## 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 get -u github.com/swaggo/swag/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 [gin-swagger](https://github.com/swaggo/gin-swagger) by using:
```sh
$ go get -u github.com/swaggo/gin-swagger
$ go get -u github.com/swaggo/files
```
And import following in your code:
```go
import "github.com/swaggo/gin-swagger" // gin-swagger middleware
import "github.com/swaggo/files" // swagger embed files
```
### Canonical example:
```go
package main
import (
"github.com/gin-gonic/gin"
swaggerFiles "github.com/swaggo/files"
"github.com/swaggo/gin-swagger"
_ "github.com/swaggo/gin-swagger/example/basic/docs" // docs is generated by Swag CLI, 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 petstore.swagger.io
// @BasePath /v2
func main() {
r := gin.New()
url := ginSwagger.URL("http://localhost:8080/swagger/doc.json") // The url pointing to API definition
r.GET("/swagger/*any", ginSwagger.WrapHandler(swaggerFiles.Handler, url))
r.Run()
}
```
5. Run it, and browser to http://localhost:8080/swagger/index.html, you can see Swagger 2.0 Api documents.
![swagger_index.html](https://user-images.githubusercontent.com/8943871/60704329-b7ab0680-9f36-11e9-9184-5c638c05e9c5.png)
6. If you want to disable swagger when some environment variable is set, use `DisablingWrapHandler`
### Example with disabling:
```go
package main
import (
"github.com/gin-gonic/gin"
swaggerFiles "github.com/swaggo/files"
"github.com/swaggo/gin-swagger"
_ "github.com/swaggo/gin-swagger/example/basic/docs" // docs is generated by Swag CLI, 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 petstore.swagger.io
// @BasePath /v2
func main() {
r := gin.New()
// use ginSwagger middleware to
r.GET("/swagger/*any", ginSwagger.DisablingWrapHandler(swaggerFiles.Handler, "NAME_OF_ENV_VARIABLE"))
r.Run()
}
```
Then, if you set envioment variable `NAME_OF_ENV_VARIABLE` to anything, `/swagger/*any`
will respond 404, just like when route unspecified.
