**A parser for URNs**.

> As seen on [RFC 2141](https://datatracker.ietf.org/doc/html/rfc2141), [RFC 7643](https://datatracker.ietf.org/doc/html/rfc7643#section-10), and on [RFC 8141](https://datatracker.ietf.org/doc/html/rfc8141).

[API documentation](https://godoc.org/github.com/leodido/go-urn).

Starting with version 1.3 this library also supports [RFC 7643 SCIM URNs](https://datatracker.ietf.org/doc/html/rfc7643#section-10).

Starting with version 1.4 this library also supports [RFC 8141 URNs (2017)](https://datatracker.ietf.org/doc/html/rfc8141).

## Installation

```
go get github.com/leodido/go-urn
```

## Features

1. RFC 2141 URNs parsing (default)
2. RFC 8141 URNs parsing (supersedes RFC 2141)
3. RFC 7643 SCIM URNs parsing
4. Normalization as per RFCs
5. Lexical equivalence as per RFCs
6. Precise, fine-grained errors

## Performances

This implementation results to be really fast.

Usually below 400 ns on my machine<sup>[1](#mymachine)</sup>.

Notice it also performs, while parsing:

1. fine-grained and informative erroring
2. specific-string normalization

## Example

For more examples take a look at the [examples file](examples_test.go).

```go
package main

import (
	"fmt"
	"github.com/leodido/go-urn"
)

func main() {
	var uid = "URN:foo:a123,456"

// Parse the input string as a RFC 2141 URN only
	u, e := urn.NewMachine().Parse(uid)
	if e != nil {
		fmt.Errorf(err)

return
	}

fmt.Println(u.ID)
	fmt.Println(u.SS)

// Output:
	// foo
	// a123,456
}
```

```go
package main

import (
	"fmt"
	"github.com/leodido/go-urn"
)

func main() {
	var uid = "URN:foo:a123,456"

// Parse the input string as a RFC 2141 URN only
	u, ok := urn.Parse([]byte(uid))
	if !ok {
		panic("error parsing urn")
	}

fmt.Println(u.ID)
	fmt.Println(u.SS)

// Output:
	// foo
	// a123,456
}
```

```go
package main

import (
	"fmt"
	"github.com/leodido/go-urn"
)

func main() {
	input := "urn:ietf:params:scim:api:messages:2.0:ListResponse"

// Parsing the input string as a RFC 7643 SCIM URN
	u, ok := urn.Parse([]byte(input), urn.WithParsingMode(urn.RFC7643Only))
	if !ok {
		panic("error parsing urn")
	}

fmt.Println(u.IsSCIM())
	scim := u.SCIM()
	fmt.Println(scim.Type.String())
	fmt.Println(scim.Name)
	fmt.Println(scim.Other)

// Output:
	// true
	// api
	// messages
	// 2.0:ListResponse
}
