+# structtag [![GoDoc](http://img.shields.io/badge/go-documentation-blue.svg?style=flat-square)](http://godoc.org/github.com/fatih/structtag) [![Build Status](https://travis-ci.org/fatih/structtag.svg?branch=master)](https://travis-ci.org/fatih/structtag)
+
+structtag provides an easy way of parsing and manipulating struct tag fields.
+Please vendor the library as it might change in future versions.
+
+# Install
+
+```bash
+go get github.com/fatih/structtag
+```
+
+# Example
+
+```go
+package main
+
+import (
+	"fmt"
+	"reflect"
+	"sort"
+
+	"github.com/fatih/structtag"
+)
+
+func main() {
+	type t struct {
+		t string `json:"foo,omitempty,string" xml:"foo"`
+	}
+
+	// get field tag
+	tag := reflect.TypeOf(t{}).Field(0).Tag
+
+	// ... and start using structtag by parsing the tag
+	tags, err := structtag.Parse(string(tag))
+	if err != nil {
+		panic(err)
+	}
+
+	// iterate over all tags
+	for _, t := range tags.Tags() {
+		fmt.Printf("tag: %+v\n", t)
+	}
+
+	// get a single tag
+	jsonTag, err := tags.Get("json")
+	if err != nil {
+		panic(err)
+	}
+	fmt.Println(jsonTag)         // Output: json:"foo,omitempty,string"
+	fmt.Println(jsonTag.Key)     // Output: json
+	fmt.Println(jsonTag.Name)    // Output: foo
+	fmt.Println(jsonTag.Options) // Output: [omitempty string]
+
+	// change existing tag
+	jsonTag.Name = "foo_bar"
+	jsonTag.Options = nil
+	tags.Set(jsonTag)
+
+	// add new tag
+	tags.Set(&structtag.Tag{
+		Key:     "hcl",
+		Name:    "foo",
+		Options: []string{"squash"},
+	})
+
+	// print the tags
+	fmt.Println(tags) // Output: json:"foo_bar" xml:"foo" hcl:"foo,squash"
+
+	// sort tags according to keys
+	sort.Sort(tags)
+	fmt.Println(tags) // Output: hcl:"foo,squash" json:"foo_bar" xml:"foo"
+}
+```
