Go Tag

The gotag command adds tags to existing go structs in go files.

Run with -help for usage information.

Example

Input: sample.go

package main

type Foo struct {
	Foo string `json:"-"`
	Bar map[int]interface{}
	baz int

	Nax struct {
		Hello string
	}
}

Execution:

$ gotag -offset sample.go:#50 -tag json -suffix ",omitempty"

Will result sample.go to change to:

package main

type Foo struct {
    Foo string              `json:"-"`
    Bar map[int]interface{} `json:"Bar,omitempty"`
    baz int

    Nax struct {
        Hello string
    } `json:"Nax,omitempty"`
}
