tag help

For read tags use

tag read -in "path/to/file"
# example output
version: id3v2.4
description         : subtitle
track number        : 12/12
author              : Kitten
catalog number      : catalogcat
bmp                 : 777
conductor           : catconductor
copyright           : 2019
album               : CatAlbum
comment             : catcomment

for save meta information use

tag read -in "path/to/file" -out "path/to/outputfile.json"

Now supported only json output file

How to use

tags, err := tag.ReadFile("song.mp3")
if err != nil {
return err
}
fmt.Println(tags.GetTitle())

tag.ReadFile or tag.Read return interface Metadata:

package tag

type Metadata interface {
	GetMetadata
	SetMetadata
	DeleteMetadata
	SaveMetadata
}

type GetMetadata interface {
	GetAllTagNames() []string
	GetVersion() Version
	GetFileData() []byte // all another file data

	GetTitle() (string, error)
	GetArtist() (string, error)
	GetAlbum() (string, error)
	GetYear() (int, error)
	GetComment() (string, error)
	GetGenre() (string, error)
	GetAlbumArtist() (string, error)
	GetDate() (time.Time, error)
	GetArranger() (string, error)
	GetAuthor() (string, error)
	GetBMP() (int, error)
	GetCatalogNumber() (int, error)
	GetCompilation() (string, error)
	GetComposer() (string, error)
	GetConductor() (string, error)
	GetCopyright() (string, error)
	GetDescription() (string, error)
	GetDiscNumber() (int, int, error) // number, total
	GetEncodedBy() (string, error)
	GetTrackNumber() (int, int, error) // number, total
	GetPicture() (image.Image, error)
}

type SetMetadata interface {
	SetTitle(title string) error
	SetArtist(artist string) error
	SetAlbum(album string) error
	SetYear(year int) error
	SetComment(comment string) error
	SetGenre(genre string) error
	SetAlbumArtist(albumArtist string) error
	SetDate(date time.Time) error
	SetArranger(arranger string) error
	SetAuthor(author string) error
	SetBMP(bmp int) error
	SetCatalogNumber(catalogNumber int) error
	SetCompilation(compilation string) error
	SetComposer(composer string) error
	SetConductor(conductor string) error
	SetCopyright(copyright string) error
	SetDescription(description string) error
	SetDiscNumber(number int, total int) error
	SetEncodedBy(encodedBy string) error
	SetTrackNumber(number int, total int) error
	SetPicture(picture image.Image) error
}

type DeleteMetadata interface {
	DeleteAll() error

	DeleteTitle() error
	DeleteArtist() error
	DeleteAlbum() error
	DeleteYear() error
	DeleteComment() error
	DeleteGenre() error
	DeleteAlbumArtist() error
	DeleteDate() error
	DeleteArranger() error
	DeleteAuthor() error
	DeleteBMP() error
	DeleteCatalogNumber() error
	DeleteCompilation() error
	DeleteComposer() error
	DeleteConductor() error
	DeleteCopyright() error
	DeleteDescription() error
	DeleteDiscNumber() error
	DeleteEncodedBy() error
	DeleteTrackNumber() error
	DeletePicture() error
}

type SaveMetadata interface {
	SaveFile(path string) error
	Save(input io.WriteSeeker) error
}

Also you can read defined format. For Example:

package main

import (
	"fmt"
	"github.com/ghenry22/tag"
	"os"
)

func Read() error {
	file, err := os.Open("path/to/file")
	if err != nil {
		return err
	}
	defer file.Close()

	id3v2, err := tag.ReadID3v24(file)
	if err != nil {
		return err
	}

	// Get tag value by name
	value, err := id3v2.GetString("TIT2")
	if err != nil {
		return err
	}
	fmt.Println("title: " + value)

	// Set tag value
	err = id3v2.SetString("TIT2", "Title")
	if err != nil {
		return err
	}

	// User defined tags
	value, err = id3v2.GetStringTXXX("MYTAG")
	if err != nil {
		return err
	}
	fmt.Println("my tag: " + value)

	// Set user tag
	err = id3v2.SetStringTXXX("MYTAG222", "Dogs")
	if err != nil {
		return err
	}

	// Save changes
	err = id3v2.SaveFile("path/to/file")
	if err != nil {
		return err
	}
}

Functions

func ByteToInt 

func ByteToInt(data []byte) int

Convert byte to int.

func ByteToIntSynchsafe 

func ByteToIntSynchsafe(data []byte) int

ByteToIntSynchsafe - Convert byte to int In some parts of the tag it is inconvenient to use the unsychronisation scheme because the size of unsynchronised data is not known in advance, which is particularly problematic with size descriptors. The solution in ID3v2 is to use synchsafe integers, in which there can never be any false synchs. Synchsafe integers are integers that keep its highest bit (bit 7) zeroed, making seven bits out of eight available. Thus a 32 bit synchsafe integer can store 28 bits of information.

func DecodeString 

func DecodeString(b []byte, encoding string) (string, error)

func DecodeUTF16 

func DecodeUTF16(b []byte) (string, error)

Decode UTF-16 Little Endian to UTF-8.

func DecodeUTF16BE 

func DecodeUTF16BE(b []byte) (string, error)

Decode UTF-16 Big Endian To UTF-8.

func GetBit 

func GetBit(data byte, index byte) byte

Return bit value Index starts from 0 bits order [7,6,5,4,3,2,1,0].

func GetEncoding 

func GetEncoding(code byte) string

func GetMap 

func GetMap(metadata Metadata) map[string]interface{}

nolint:gocyclo

func GetString 

func GetString(b []byte) (string, error)

func IntToByteSynchsafe 

func IntToByteSynchsafe(data int) []byte

func SetBit 

func SetBit(data *byte, bit bool, index byte)

func SetString 

func SetString(value string) []byte

func SplitBytesWithTextDescription 

func SplitBytesWithTextDescription(data []byte, encoding string) [][]byte

func TextEncoding 

func TextEncoding(b []byte) string

TextEncoding - Text Encoding for text frame header First byte determinate text encoding. If ISO-8859-1 is used this byte should be $00, if Unicode is used it should be $01 Return text encoding. E.g. "utf8", "utf16", etc.
