# id3v2

Implementation of ID3 v2.3 and v2.4 in native Go.

## Installation

```
go get -u github.com/bogem/id3v2/v2
```

## Documentation

https://pkg.go.dev/github.com/bogem/id3v2/v2

## Usage example

```go
package main

import (
"fmt"
"log"

"github.com/bogem/id3v2/v2"
)

func main() {
tag, err := id3v2.Open("file.mp3", id3v2.Options{Parse: true})
if err != nil {
log.Fatal("Error while opening mp3 file: ", err)
}
defer tag.Close()

// Read tags
fmt.Println(tag.Artist())
fmt.Println(tag.Title())

// Set tags
tag.SetArtist("Aphex Twin")
tag.SetTitle("Xtal")

comment := id3v2.CommentFrame{
Encoding: id3v2.EncodingUTF8,
Language: "eng",
Description: "My opinion",
Text: "I like this song!",
}
tag.AddCommentFrame(comment)

// Write tag to file.mp3
if err = tag.Save(); err != nil {
log.Fatal("Error while saving a tag: ", err)
}
}
```

## Read multiple frames

```go
pictures := tag.GetFrames(tag.CommonID("Attached picture"))
for _, f := range pictures {
pic, ok := f.(id3v2.PictureFrame)
if !ok {
log.Fatal("Couldn't assert picture frame")
}

// Do something with picture frame
fmt.Println(pic.Description)
}
```

## Encodings

For example, if you want to set comment frame with custom encoding,
you may do the following:

```go
comment := id3v2.CommentFrame{
Encoding: id3v2.EncodingUTF16,
Language: "ger",
Description: "Tier",
Text: "Der Löwe",
}
tag.AddCommentFrame(comment)
```

`Text` field will be automatically encoded with UTF-16BE with BOM and written to w.

UTF-8 is default for v2.4, ISO-8859-1 - for v2.3.
