func RewriteTag 

func RewriteTag(config RewriteTagConfig) (string, error)

RewriteTag overwrites json tag by convert function and return formatted source code

Example 
file := pathutils.Abs("testdata/rewritejsontag.go")
config := RewriteTagConfig{
	File:        file,
	Omitempty:   true,
	ConvertFunc: strcase.ToLowerCamel,

}
result, err := RewriteTag(config)
if err != nil {
	panic(err)
}
fmt.Println(result)

Output:

package main

type base struct {
	Index string `json:"index,omitempty"`
	Type  string `json:"type,omitempty"`
}

type struct1 struct {
	base
	Name       string `json:"name,omitempty"`
	StructType int    `json:"structType,omitempty" dd:"awesomtag"`
