Installation

Installs in your $GOPATH

go get github.com/makebyte/mutago

import (
"github.com/makebyte/mutago"
)

Note : The examples folder contains implementations of all the methods below.

Read methods

Open file

f, err := mutago.Open("file.mp3")
if err != nil {
// Handle error
}
defer f.Close() // Always good to close after using

Provides a list of available tags

tags := f.List() // List() Provides an array of tags in the file. 

Provides values of basic tags

/*
For basic tags such as song title, album name and artist there are seperate methods. 
(So that you don't need to know the ID3 tag identifier)
*/
title, err := f.Title()
album, err := f.Album()
artist, err := f.Artist()

Provides values of other tags

/*
For more advanced tags such as comments, year, lead singer, etc.
Use Get() method that fetches the ID3 tag's value, provided the tag identifier.
For a list of valid tags check id3.org.

Get() will return an error if the tag is invalid or doesn't exist in the file.
*/

text, err := f.Get("TXXX")
lead, err := f.Get("TPE1")

Write methods

/*
Yet to be built.

Will be added soon.
