Gogen is lightweight resourceful code generator library written entirely in Go. It is based on resource definitions, pipes and executable configuration files.
To start with Gogen, we'll need resources(models, api schemes, blueprints, ...) and generators that should be used to generate results. We'll then mix everything in one or more configuration files, that will allow us to generate code.
Let's start by creating config.go file with already existing resources and generators.
package main
import (
"github.com/gophergala2016/gogen"
"github.com/gophergala2016/gogen/generator"
"github.com/gophergala2016/gogen/model"
)
func main() {
// Define adds resources for the generators, this way
// we are adding the user model that is already defined
// for us to the generator resources
gogen.Define(model.User)
// set output for the generator that is generating models
generator.Model.SetOutputDir("./model")
// Pipe is set of generators. More pipes can go in parallel
// and everything in pipe is executed in serie. This allows
// generators to have dependencies on each other
//
// This is creating our pipe with the ModelGenerator in it
gogen.Pipe(
generator.Model,
)
// start the generator
if err := gogen.Generate(); err != nil {
panic(err)
}
}This configuration file will create new folder model in the current working directory, with generated user model file.
