Overview

Package swipe is a code generation tool that automates the creation of repetitively used code. Configuration parameters are presented in Swipe as parameters of the Golang function, using explicit initialization instead of global variables or reflections.

Swipe generates code using an option: a function that calls functions that define the generation parameters. Using Swipe, you describe the generation parameters in the option, and then Swipe generates the code.

1. The "function as an option" approach is used to configure generation.

2. All code that is not associated with the generation parameters will not be copied to the generated file.

3. Function with a `swipe.Build` option inserted in the body. `swipe.Build` will not be transferred to the generated code.

If you want the generate code, you can run:

swipe ./pkg/...

Full example:

 // +build swipe

 package jsonrpc

 import (
	  "github.com/swipe-io/swipe/v2/fixtures/service"

	  . "github.com/swipe-io/swipe/v2/pkg/swipe"
 )

 func Swipe() {
	Build(
		Service(
			(*service.Interface)(nil),
			Transport("http",
				ClientEnable(),
				Openapi(
					OpenapiOutput("/../../docs"),
					OpenapiVersion("1.0.0"),
				),
			),
			Logging(),
			Instrumenting(),
		),
	  )
 }
