        gojsontagstringer [flags] -type T files... # Must be a single package
For more information, see:
        https://pkg.go.dev/github.com/sgtsquiggs/gojsontagstringer

Examples

Local Files

Given file car.go:

package car

type Car struct {
	Make  string `json:"make"`
	Model string `json:"model"`
}

Then executing command:

$ gojsontagstringer -type Car car.go

Resulting with file car_jsontags.go:

// Code generated by "gojsontagstringer -type Car car.go"; DO NOT EDIT.

package car

const (
	CarMakeJson  = "make"
	CarModelJson = "model"
)

3rd Party Library

Assumes that the 3rd party package is available to the module in the current working directory.

Executing command:

$ gojsontagstringer -type BoolValue google.golang.org/protobuf/types/known/wrapperspb

Resulting with file boolvalue_jsontags.go:

// Code generated by "gojsontagstringer -type BoolValue google.golang.org/protobuf/types/known/wrapperspb"; DO NOT EDIT.

package local_package

const (
	BoolValueValueJson = "value"
)
