entcpkg example
An example of using entc (ent codegen) as package rather than an executable.
In this example, we have a file named entc.go under the ./ent directory, that holds the
configuration for the codegen:
// +build ignore
package main
import (
"log"
"github.com/facebookincubator/ent/entc"
"github.com/facebookincubator/ent/entc/gen"
"github.com/facebookincubator/ent/schema/field"
)
func main() {
err := entc.Generate("./schema", &gen.Config{
Header: `
// Copyright (c) Facebook, Inc. and its affiliates. All Rights Reserved.
// This source code is licensed under the Apache 2.0 license found
// in the LICENSE file in the root directory of this source tree.
// Code generated (@generated) by entc, DO NOT EDIT.
`,
IDType: &field.TypeInfo{Type: field.TypeInt},
})
if err != nil {
log.Fatal("running ent codegen:", err)
}
}
As you can see, the file is tagged with // +build ignore in order to not include it
in the ent package. In order to run the codegen, run the file itself (using go run)
or run go generate ./ent. The generate.go file holds the go run command:
package ent
//go:generate go run entc.go
The generate.go file is preferred if you have many generate pragmas in your project.
