Partial - generating partial structs for golang

Define a single struct, and then split it into multiple.

Installation

go install github.com/moevis/partial

Usage

Using tag "partial" and "+/-" to include or exclude field. For example, if you have a models.go file like following code.

package models

//go:generate partial -type=Person $GOFILE

type Person struct {
  // define a struct naming PersonWithName with a single field - "Name"
  Name     string `partial:"PersonWithName,PersonWithNameAndAge"`
  Age      int    `partial:"PersonWithNameAndAge"`
  // define a struct without Password field
  Password string `partial:"-NoPasswordPerson"`
}

Run command:

go generate

And then you will get three files in the same folder of models.go:

personwithname.go
personwithnameandage.go
nopasswordperson.go

Content of personwithname.go

package models

type PersonWithName struct {
  Name string
}

Content of personwithnameandage.go

package models

//go:generate partial -type=Person $GOFILE

type Person struct {
  // define a struct naming PersonWithName with a single field - "Name"
  Name     string `partial:"PersonWithName,PersonWithNameAndAge"`
  Age      int    `partial:"PersonWithNameAndAge"`
}
